Local land use policies can shape the sustainability of urban systems, but integrated land use at the local level is challenging since it requires the coordination of multiple semi-independent agencies within cities to effectively address collective actions problems and overcome functional divisions. Although this problem is widely acknowledged, systematic examination of what factors are related to internal coordination of land use functions is lacking. This research investigates what influences the extent to which cities coordinate across functional areas to promote integrative land use decision making. I address this question by first describing a conceptual framework drawing from institutional collective action (ICA) perspectives to understand internal city collaboration across policy functions. I then advance explanations linking institutions and community characteristics to the degree of coordination in municipal land use. Using a 2015 survey of 1124 U.S. cities, I test the hypothesized relationships based on the functional institutional collective action framework. The findings reveal that political institutions, city operation of utilities, elected officials support, and fiscal capacity increase coordination. In conclusion the implications of the findings for theory and land use planning research are discussed.
