Setback

A setback is the minimum distance a structure must be located from a property line, set by local zoning code. Setbacks vary by zoning district and structure type — front, side, and rear setbacks are usually different. ADUs in California are allowed at 4-foot side and rear setbacks under state law, regardless of local zoning.

Why this matters for renovation projects

Setback shows up on permits, contracts, or estimates that Renology covers across LA, San Diego, San Francisco, Seattle, Portland, and Denver. Most homeowners encounter the term once a project is already mid-flight, when there is no time to learn its mechanics without slowing the contractor. Knowing what it means before signing the contract is the difference between a clean project and an avoidable surprise. For how Renology calibrates cost ranges against permit valuations and contractor invoices, see the methodology.
