Confirm lot coverage, setbacks, height limits, and use permissions for accessory units in the local zoning code and the city planning office before submitting construction plans. For general planning and zoning procedures consult the City of Miami Planning office Planning Department[1]. For permit filing and building plan review use the Building Department resources Building Department[2].
