What zoning decides
Every city or county divides land into zoning districts, such as R-1 for single-family homes. The zoning code sets what you can build on your lot, how big, how tall and where.
Zoning is separate from the building code: zoning decides what and where, the building code decides how it is built safely.
Key terms
- Setback – minimum distance from a property line to the building.
- Lot coverage – share of the lot covered by buildings, often 30–50 %.
- Floor area ratio (FAR) – total floor area divided by lot area.
- Easement – a strip others may use, for example for utilities; usually no building.
- Variance – permission to deviate from the zoning code, decided at a public hearing.
How to find your rules
Look up your parcel on the city or county GIS map to find its zoning district, then read that district in the zoning code. Check your deed and HOA covenants too – they can be stricter than zoning.
Frequently asked questions
What if my design breaks a setback?
You can redesign or apply for a variance. Variances need a hearing and are granted only for real hardships, so plan inside the setbacks when you can.
Codes and zoning vary by state, county and city. Always check with your local building department and HOA before you build.
