First, you should research the zoning regulations in your area.
Some big cities are relaxing laws on tiny homes to increase the housing supply, while many others still have stringent limitations on what can be built on private property.
Zoning regulations are often listed with a property’s address on a city’s zoning map. Do a fast Google search with your city’s name and the terms “zoning map” or “zoning office.
If you are still having trouble, you should contact the city’s planning and construction division.
