Home Improvement Contractors in San Francisco, CA

The median home in the city of San Francisco was built in 1946, older than the U.S. median of 1980 and older than the California median of 1976.¹ Older housing stock means a contractor's first job is finding what is behind the finish - wiring, plumbing and roof decking - before a price is final. The stock is old by national standards: 76% of San Francisco's housing units were built before 1980 (U.S. 50%), and only 8% since 2010.¹ Pre-1940 houses often have unlined chimneys, plaster walls and balloon framing, which change the scope of almost every trade.

Owner-occupied homes in San Francisco are older than rentals: a median build year of 1941 against 1953.¹ Where owner-occupied homes skew older, a repair-versus-replace conversation is the usual starting point rather than a like-for-like swap. Most housing units in San Francisco are not detached houses: 49% are in buildings of five or more units and only 18% are detached single-family homes.¹ With most units in multi-family buildings, condo and HOA approvals sit alongside the permit for interior work.
