A setback is the minimum distance your local zoning code requires between a structure and a property line. Together, the front, rear, and side setbacks define the building envelope — the area of your lot where construction is allowed.

Why do setback requirements vary so much?

Every city and county writes its own zoning code, and within one city the requirements change by zoning district, structure type, structure size and height, and lot conditions like corner lots, easements, and overlay districts. For some project types, such as ADUs, state laws can also override local rules.

How do I find the setback requirements for my property?

Find your parcel's zoning designation using your city or county GIS map or planning department, then read the dimensional standards for that district in the municipal code — or call the planning department and ask for your address. Always confirm the final numbers with your local zoning or permit office before building.

Do fences have setbacks?

Many codes allow fences on or near the property line, but permitted fence height is usually lower in front yards than in side and rear yards, and corner lots often have visibility rules near intersections. Some jurisdictions require taller fences to be set back or permitted.

Do pools have their own setbacks?

Yes. Pools commonly have setbacks measured from the water's edge, separate setbacks for pool equipment, required distances from the house, septic systems, and utility lines, plus barrier and fencing requirements driven by safety codes.

Property Setbacks Explained

Setbacks are the minimum distances your local zoning code requires between a structure and your property lines. They vary by jurisdiction, zoning district, and structure type — this guide explains what setbacks are, why they vary, how to confirm them with your local zoning office, and what to check for ADUs, sheds, decks, fences, pergolas, and pools.
