An Index to Identify and Classify the Spectrum of U.S. Peri-Urban Informal Subdivisions

This paper proposes a replicable, data-driven index to identify informal subdivisions and measure levels of peri-urban housing informality. Dallas (Texas) and Catawba (North Carolina) county assessment data, a review of the literature, and insights from qualitative research in North Texas yielded variables which were reduced to two factors through exploratory factor analysis. We identified 128 and fifty-three highly informal subdivisions in Dallas and Catawba counties, respectively. This work highlights the pervasiveness of peripheral informal subdivisions and helps guide planners’ efforts to locate and assist the most precarious subdivisions.

THE FORMAL PRODUCTION OF INFORMAL HOUSING FOR THE RICH: Informality Pathways in the Eastern Hills of Bogotá

AbstractHousing informality in wealthy contexts is an overlooked phenomenon, particularly in the global South. This article addresses the role of public institutions in the production of housing informality among the wealthy. For this purpose, it analyses the operation of public institutions in relation to the proliferation of luxurious villas in the eastern hills of Bogotá. Three villas were selected as archetypes of informal urbanization among the elite in the eastern hills, and their stories—or informality pathways—were reconstructed through interviews, maps and policy documents. The article aims to unveil how public institutions have contributed to the creation of informal spaces, often in collusion with private entities. Specifically, public institutions demonstrated conflicting internal agencies and multi‐level fragmentation, resulting in flexible regulations tailored to fit the construction practices of the elite. These characteristics were instrumental in establishing spaces of exception for the wealthy in the eastern hills of Bogotá and will likely be mirrored in other informal settlements in the global South.

The effect of dwelling size on the mental health and quality of life of female caregivers living in informal tiny homes in Hong Kong

BackgroundAlthough the adverse impact of substandard informal housing has been widely documented, most studies concentrated on developing societies, thereby leaving informal housing in developed regions underexplored. This study examines Hong Kong, where limited dwelling size is a distinctive feature that characterises informal housing, to explore the impact of housing informality on mental health, with a particular focus on dwelling size. It centers on subdivided units (SDUs), which are tiny compartments partitioned from a large domestic quarter, to understand how housing informality and housing size affect the mental well-being of female caregivers, who typically bear the brunt of the housework.MethodsIn partnership with nongovernment organisations in three SDU-abundant districts, this mixed-methods study conducted a survey on 413 female caregivers aged 18—65 and qualitative research combining ethnographic observations and in-depth interviews on 36 families living in SDUs in Hong Kong between 2021 and 2023. The mental health outcomes and health-related quality of life (HRQoL) of the participants were assessed by using the Depression, Anxiety, and Stress Scale-21 and a EuroQol-5 Dimension-5 Level questionnaire.ResultsDepression, anxiety and stress were prevalent across the female caregivers living in SDUs (12.4%), as well as a significantly lower HRQoL compared with that of the general population (0.882 vs. 0.919). Findings showed that a total floor area smaller than 13.0 m2 was associated with increased likelihood of experiencing anxiety and depression and reduced HRQoL. Cramped living space adversely affected the caregivers’ well-being through the 1) physical, 2) relational and 3) personal aspects of home experiences. Negative experiences at home can cause housework burnout, exacerbate family conflicts and lead to feelings of repression and low self-efficacy.ConclusionsThis study contributes to the understanding of the consequences of housing informality in diverse geographical contexts and illuminates the effect of dwelling size by identifying the mechanisms through which housing size can affect the mental well-being of residents, which may vary depending on their family status. The findings yield important policy implications, including the need to establish a minimum space standard for subdivided residential dwellings and ensure equitable access to community spaces for deprived families.

Three theses on informal housing in Europe

This editorial introduction to the Special Issue ‘The rules, institutions and politics of housing informality in Europe’ argues for a more holistic interpretation to housing informality in Europe as a critical heuristic for re-thinking the dynamics of informality in the global North. In so doing, it offers three modest theses. First, housing informality is an endogenous phenomenon in the development of European cities, closely connected to the logics of capitalist modernity and currently located at the intersection of new patterns of forced migration and an ever-intensifying housing crisis. Second, housing informality is (also) a by-product of direct forms of public support, toleration and legitimation, as well as the consequence of deliberate (in)action by the State. This results in a clear public politics of informal space, in the framework of which informal housing is an instrument of governmentality in the hands of ruling elites. Third, housing informality is normatively ambiguous. In fact, informal dwelling practices create an archipelago of institutional micro-geographies at the city scale, that generate, in turn, heterogeneous spheres of urban citizenship rights. This selective spatial autonomy can be inhabited as much by processes of rights expansion, emancipation and solidarity as well as by practices of right-restriction, exploitation and precarization.

Conversions: The emerging informalisation of housing in the Global North

Housing informality in the Global North is becoming an increasingly important topic amongst planners. In this paper, we build on recent debates on informality and planning to highlight forms of housing informality that emerge at the intersection of affordability crises, and capitalism’s new extractivist frontiers through digital platforms. Using the lens of conversions, we show how the flexible transformation of building uses, from commercial to residential (and vice versa) by landlords create new and emerging forms of informality and subsequent planning challenges. These conversions present three specific characteristics: platform-led rapidity, regulatory grey areas, and professional intermediation. These are being extended through corporate and institutional alignments with for-profit motives of rent extraction, and by rapid real estate investment dynamics. Such conversions do not involve material of physical alterations to the built form and thus remain invisible. They exist flexibly in the grey areas of the law, and as a consequence, the rights of tenants, users and those of the wider community become weaker. We focus on examples of property guardianship and digital platforms-enabled home-sharing in England to illustrate our argument, and propose emphasising conversions as dynamic processes to draw attention to their implications for planning theory and practice.

An Overlooked Phenomenon? Reflecting on Elite Housing Informality and its Potential Sustainability Implications

Urban informality is one of the most hotly debated concepts in the fields of geography and urban studies. However, one narrative that has assumed hegemony and dominated conventional scholarship is the view that it is peculiar to the urban poor or subaltern group. In this paper, I contend that little to no empirical attention has been paid to an essential piece of the conceptual mosaic of informality. I reflect on housing informality by elites or upper-income urbanites and highlight its associated Janus-faced governance approach. I argue that the deliberate disregard and legitimization of elite informal developments pose crucial sustainability implications.

BOATS AS HOUSING IN OXFORD, UK: Trajectories of Informality in a High‐Income Context

AbstractIn this article I aim to shed light on boat dwelling as an increasingly popular housing practice in the UK. I investigate the changing nature of this practice in times of housing crisis and of the connection between formal and informal approaches, and discuss how decentralized urban actors influence and safeguard their visions of housing. My investigation concentrates on three intertwined strategies boaters in Oxford use to deal with growing regularization and commodification pressures: (non)compliance, formalization and staying under the radar. My findings challenge several assumptions about housing informality in the global North and document the diverse trajectories that informal processes may take. My analysis reveals that informal and semi‐formal solutions are not simply ‘tolerated’ or ‘overlooked’ by the state, but co‐produced by urban dwellers through a repertoire of everyday actions and ad hoc advocacy approaches. The construction of specific trajectories of informal housing emerges at the interface of complex agendas and attitudes that go beyond the generalized roles attributed to the key urban sectors.

Toward a fine-grained understanding of informality: Subjective meanings, perceptions, and expectations in informal housing trajectories

This article focuses on the role of subjective meanings in the production of informal housing. It argues that, although individual and family meanings, aspirations, perceptions, and expectations have usually been overlooked in studies on urban informality, their analysis is fundamental for a sophisticated understanding of the genesis, features, and developing trajectories of informal housing. To this end, the article investigates the informalization process of temporary self-promoted housing units (the so-called casette, i.e. “little houses”) built in the aftermath of the 2009 earthquake in the city of L’Aquila, Italy. Although it is exceptional, the phenomenon of the casette illuminates several traits of other informal housing practices. Thus, it offers two interrelated conceptual insights for a deeper, fine-grained understanding of the varied ontologies of housing informality. First, it illustrates the concurrence of simultaneous drivers, differing in nature (e.g. subjective and objective, structural and agency-related, micro and macro) at the root of the production of informal space, where a key role is also played by inhabitants’ meanings, aspirations, perceptions, and expectations. Second, it shows that informality is not a fixed and unambiguous state. On the contrary, it is a field traversed by intertwined forces in a perpetual state of tension, so that a housing unit can move through different shades of (il)legality entailing varied combinations of subjective and objective drivers.

Mapping and Assessment of Housing Informality Using Object-Based Image Analysis: A Review

Research on the detection of informal settlements has increased in the past three decades owing to the availability of high- to very-high-spatial-resolution satellite imagery. The achievement of development goals, such as the Sustainable Development Goals, requires access to up-to-date information on informal settlements. This review provides an overview of studies that used object-based image analysis (OBIA) techniques to detect informal settlements using remotely sensed data. This paper focuses on three main aspects: image processing steps followed when detecting informal settlements using OBIA; informal settlement indicators and image-based proxies used to detect informal settlements; and a review of studies that extracted and analyzed informal settlement land use objects. The success of OBIA in detecting informal settlements depends on the understanding and selection of informal settlement indicators and image-based proxies used during image classification. To meet the local ontology of informal settlements, the transfer of OBIA mapping techniques requires the fine-tuning of the rulesets. Machine learning OBIA techniques using image proxies derived from multiple sensors increase the opportunities for detecting informal settlements on the city or national level.

HOUSING INFORMALITY IN THE GLOBAL SOUTH: Insights from a Policy Comparison between Accra and Buenos Aires

AbstractInformal settlement growth in various countries has led to distinctive actions that enhance low‐income populations’ accessibility to adequate, safe and affordable housing and basic services. This trend indicates the need for comparative studies between countries and cities to understand the factors that lead to policy learning opportunities. We conducted an experimental comparison between Accra, Ghana, and Buenos Aires, Argentina, to understand, first, how policies on informal settlements have been formed, and secondly, what inquiries should be made to address housing informality in the global South. A comparison shows that these cities/countries have shared moments of neoliberalization and that their poor residents have experienced similar struggles regarding housing availability and the pursuit of extensive governmental interventions. Therefore, their experiences are worth examining. Our comparison indicates that first, Buenos Aires/Argentina has adopted more inclusive policies regarding informal dwellers than Accra/Ghana, and secondly, that diversifying housing solutions are an inevitable dynamic in cities/countries experiencing a surge in housing pressure across classes, races and geographies. In this article we articulate how the governments of these countries have dealt with these challenges and conceptualize the coproduction needs of housing informality in developing countries. We encourage policymakers facing informality in the South to respond to the questions we raise about facilitating policy learning.

“They're just trying to survive”: The relationship between social vulnerability, informal housing, and environmental risks in Loíza, Puerto Rico, USA

Socially vulnerable households across the earth tend to live in informal settlements, which also are likely to be in areas that might experience flooding. Given that since the 1980s there have been more frequent and devastating hurricanes, this study asks what is the relationship between informal housing, social vulnerability, and environmental hazards in the context of a US territory? Although most research on this topic has concentrated in the Global South, there are no studies within the US disaster management system on these environmental justice topics—primarily because housing informality is heavily under studied in the US and the Global North. With the purpose of understanding the connection we conducted qualitative analysis using 30 interviews with stakeholders working on different facets of disaster recovery and mitigation in Loíza, Puerto Rico, a US territory. Loíza is a low-income Afro-Caribbean town along the coast, where about half of the homes are located within the 100-year FEMA flood maps. The findings suggest that changes need to be made regarding how local and federal government entities approach informal housing when providing assistance after the 2017 Hurricanes Irma and Maria. It is also important for planners and other decision makers to educate communities and provide recovery funding after a major disaster so that long-term risks could be reduce without displacing the local population.

Illegal short-term rentals, regulatory enforcement and informal practices in the age of digital platforms

This article analyses the challenges of controlling short-term rentals (STR) in an era of intermediation by digital platforms, focusing on the process of regulatory enforcement. Drawing on evidence from large European cities, it investigates how public authorities identify and tackle STR deemed illegal, how operators of illegal STR seek to escape detection, and the relationships between city governments and digital platforms in the process of regulatory enforcement. The article shows what digitalisation and ‘platformisation’ do to the possibility of (local) state regulation of housing informality and illegality in the European context. As platforms have been reluctant to release individualised STR listings to local authorities, the latter have had to rely on imperfect, ‘DIY’ methods of data gathering in the physical and digital worlds, in the context of attempts to regulate STR for public interest objectives such as the protection of the long-term residential stock.

Wandering in the gray: The pricing of housing restricted by land use regulation in Beijing, China

Many informalities exist in the provision of affordable housing in transitional economies such as China. China’s diverse profile of informal housing demands a broader definition of informality that includes both the absence/presence and degree of property rights. In this study, we investigate the distinct phenomenon of residential housing built on commercial use land, termed commercial land (CL) housing. CL housing is characterized by incomplete property rights because it violates regulated land uses, which is further exacerbated by policies aimed at enforcing the land use regulation. The changes in the degree of property rights of CL housing provide a natural experiment to improve understanding of the dynamics of the informal housing market in China. Drawing on a large database of housing transactions in the city of Beijing, our results suggest that on average, CL housing is priced 30% lower than formal commodity housing, increasing to over 60% in situations with a lower level of property rights. The loss in value of CL housing due to government regulation amounts to 11,483 RMB (equivalent to US $1771) per square meter. We also find evidence that CL housing facilitates investment, which may have declined as a result of the regulated CL market. Overall, our findings are of theoretical and empirical significance for understanding informal housing development in China, involving complex and dynamic property rights and requiring government regulation to address housing informality.

Reimagining (informal) housing futures in uncertain times

In an incisive piece in this Journal, Michele Lancione argues that the only way to envision new housing futures is to pay attention to places where housing precarity is lived and felt. We respond to such a discursive call by drawing on a wide-range of particular empirics—from our pedagogical engagement with housing informality in Melbourne to in-situ ethnographic empirical work in Manila and Dhaka—to elaborate three aspects of reimagining informal housing practices: a) informal housing as a site for grounding teaching and learning pedagogy; b) informal housing as a space for reflexive research; and c) informal housing as a mode of futuring. Our reflective insights, which put three cities with vastly different socio-political histories in conversation, also answer a growing call from critical urban scholars to abandon the usual comparison of similar cities and to overcome the division between global North and global South cities, offering ideas that stress mutual learning across this divide.

Rethinking Public Housing Through Squatting. The Case of Housing Rights Movements in Rome

This article analyses the contribution of housing squats and Housing Rights Movements (HRMs) in Rome in envisioning a new model of public estates that could respond to the surge and complexification of the post-2008 housing crisis. The first part of the article fleshes out the theoretical and methodological framework for investigating the peculiarities of housing squats in comparison to other forms of housing informality and urban squatting. In the second part, it analyses the development and composition of housing struggles since the post-Second World War. It then details the new demographics of the housing crisis in Rome to provide a framework for the innovation in the HRMs' confrontational politics and demands towards a more comprehensive notion of the 'right to the city'. Their emphasis upon the role of city developers and real estate agents, and the opposition towards the exclusionary nature of contemporary social welfare, have in fact redirected squatting actions towards different urban vacancies that are repurposed for habitation. I conclude by suggesting that these practices prefigure a new model of public housing estates that is economically, environmentally sustainable and socially inclusive, whereby it pivots around use value and commoning.

“Unforgotten” informal communities and the COVID-19 pandemic: Sitio San Roque under Metro Manila’s lockdown

PurposeThis paper aims to offer Sitio San Roque, an informal settlement in the Philippines as a case study to explore long-term "forgetful" urban development planning in the Philippines, and the renewed visibility of the urban poor under COVID-19 lockdown. It connects scholarship on informality to issues of housing and political rights in Metro Manila to further investigate how vulnerable communities in the Global South are faring in the pandemic.Design/methodology/approachThis is an exploration of Sitio San Roque, an informal settler community in Metropolitan "Metro" Manila, Philippines. This paper refers to recent journalistic reports pertaining to the community's ongoing evictions and arrests while under Metro Manila's "enhanced community quarantine." Furthermore, it converses with literature from disciplines including health-care policy, urban studies and recent studies on COVID-19 and vulnerable communities to critically discuss the plight of the urban poor in the pandemic-stricken Metro Manila.FindingsThe urban poor and members of informal communities such as Sitio San Roque are especially vulnerable to contracting COVID-19 because of precarious livelihoods and housing instability. The creation of informality in Metro Manila can be traced to political tensions, economic agendas and development planning since the time of Marcos' administration and also to global restructuring during the 1990s. However, also important to note is that under Metro Manila's lockdown, informal settlers are further disenfranchised and stigmatized via ongoing demolitions and evictions, as well as by processes of policing and criminalization by the state. The use of military and police personnel as a way to enforce lockdown in the metropolis further impedes on the rights of informal settlers and the urban poor.Originality/valueRecent scholarship and reports discuss the challenges for informal communities and the urban poor in navigating the COVID-19 pandemic, mainly due to their housing conditions and loss of economic stability. This paper contributes to a critical understanding of these issues by adding the dimensions of political and housing rights. It refers to the case study of members of Sitio San Roque, who have experienced continuous threats of demolitions and arrests by state police for protesting the lack of government aid under lockdown. Both military approaches of governance and housing informality work in tandem to expose the vulnerabilities of the urban poor in Metro Manila's pandemic. Finally, this paper extends on urban studies scholar Gavin Shatkin's concept of “forgetful planning” (2004) by applying his discussions to the current context. Informal settlers have long been “forgotten” by the state's development plans, but are now remembered and deemed more visible in Metro Manila's ECQ.

Postcolonial narratives and the governance of informal housing in London

Housing informality has traditionally been associated with cities in the Global South. And yet, there is growing evidence that informal practices are also present in Northern cities, especially those traditionally considered ‘successful’ or ‘developed’ such as London, in which housing pressures are most acute. This paper, drawing on detailed policy analysis and qualitative in-depth interviews, uses the example of London to examine the rise of informal housing, the ways in which it is both represented and conceptualised as a ‘problem’ of governance to be tackled, and its institutionalisation into programmes of enforcement. It focuses on the emergence of a phenomenon known as ‘beds in sheds’, or the construction of informal housing in between existing buildings. By discussing a planning issue that is generally associated with the Global South in a Global North context, the paper engages with writings on postcolonial theory. It adopts a nexus approach to examine how the issue is embedded within particular configurations of social, political, economic and cultural circumstances. The evidence indicates that the ways in which the problem is framed and understood are underpinned by colonialist views that see migrants and their socio-ethnic communities as agents of informality, whose removal or sanction will ‘solve’ the problem. The paper concludes with reflections on broader debates on informality in urban studies.

Urban informality in the Global North: (il)legal status and housing strategies of Ghanaian migrants in New York City

Different legal statuses of migrants are known to affect housing opportunities in the destination cities. The research explores the housing journeys of Ghanaian migrants in the Bronx in New York City to understand the processes by which poor documented and undocumented migrants access housing, and explores the role of legal status in housing allocation. Relying on qualitative data collected through 55 in-depth interviews with migrants, the study argues that legal status does not necessarily determine Ghanaian migrants’ access to housing. Instead, the findings suggest that undocumented migrants report better housing outcomes compared to their documented counterparts. This is organised through urban informality enabled by social networks in the Bronx’s ethnic enclave. The paper argues that, rather than legal status, the strength of one’s social ties in the Ghanaian migrant community regulates access to housing. Complicit actors, including profit-seeking providers and indifferent public authorities, allow the informal processes of housing allocation to operate. The paper calls attention to the relationship between immigration status and housing informality in the Global North and sheds light on the hidden, informal sub-markets that migrants create and occupy.

The production of informal space: A critical atlas of housing informalities in Italy between public institutions and political strategies

The paper analyses the plurality of urban informal practices that characterize contemporary Italy in the sphere of housing, focusing on its complex connections with a variety of public institutions (e.g. laws, regulations, policies and practices). The paper discusses five cases of urban informality in Italy: the squatting of public housing in Milan; Roma camps in Rome; the borgate romane (large unauthorised neighbourhoods in the capital, which were built in the 1960s and 1970s and which have subsequently undergone a long and complex process of regularization); unauthorised construction, by the middle class, of second homes in coastal areas of Southern Italy; illegal subdivision of agricultural land as a standard mechanism for urban expansion in Casal di Principe, Naples.From these cases emerges a complex picture of hybrid institutions that shape and govern housing informalities. These hybrid institutions are composed of multifaceted networks of actors, policies, practices and rules that exist in tension with each other and contribute to favouring and shaping the production of informal space in different ways (e.g. through their action, inaction and structural features). Against the backdrop of this varied institutional framework, a selective tolerance driven mainly by politically-mediated interests emerges as the distinctive feature of the public approach to housing informality in Italy.The paper aims to develop an innovative research approach to informal housing in Italy by overcoming traditional boundaries between research ‘objects’ and by looking at political uses and forms of institutionalisation that are deployed across housing informalities. By doing so, it also contributes to the literature which analyses informality through the lenses of state theory. Simultaneously, it represents a call for international research to investigate the similarities in the patterns of housing informality – and their multifaceted politics – in Mediterranean welfare states.

Examining responses to informality in the Global South: A framework for community land trusts and informal settlements

Informality has been a predominant source of affordable housing for the urban poor in the Global South. Despite many efforts to eliminate and/or improve informal settlements, these communities still prevail as one of the only housing options for low-income households burdened by exclusion, dispossession, and stigma. This article evaluates the potential for and impediments to community land trusts (CLTs) as an alternative response to informality. We compare the CLT model to predominant policy responses to informality to understand it strengths and weaknesses. Based on this analysis, we propose a conceptual framework delineating the main conditions necessary to implement the CLT model within informal settlements in the Global South. This framework informs the work of communities, governments, practitioners, and researchers pursuing an alternative response to housing informality. This study expands the existing understanding about CLTs and their possibilities for application in the Global South.
