Office build-out contractors in San Francisco, CA

An office build-out fits a leased floor or suite to a company: partitions, conference rooms, ceilings, flooring, lighting, data and power, and HVAC changes.

Who pays is set in the lease. The landlord usually gives a TI allowance toward the work, and the tenant pays for anything above it, such as furniture and specialty finishes.

What to know before you hire

An office build-out is commercial work with several trades, so it needs a B (General Building) contractor. The electrical, HVAC and plumbing can be done by the B's own crew if it holds those classes, or by licensed subs.

Questions about office build-out contractors

Does an office remodel need a permit?

In San Francisco, commercial tenant improvements and office remodels can get over-the-counter review at the Permit Center with two sets of plans (SF DBI, checked Oct 18, 2026). Check your own city before you start.

Which contractor license does a commercial build-out need?

A B (General Building) license. The B definition covers any structure for people or property and does not split homes from businesses. A B-2 license is limited to existing residential wood-frame buildings, so a B-2 contractor cannot take a store or office build-out. Fire sprinkler work needs a C-16 license or a licensed C-16 subcontractor (CSLB, B&P Code 7057).

Does a commercial contractor need workers' comp?

Any contractor with employees must carry workers' comp. A contractor with no employees can file an exemption, and a card marked exempt means the contractor told CSLB it has no employees. Ask who will work on your site. From January 1, 2028 California requires a workers' comp certificate for every license, with a narrow joint-venture exception (CSLB, checked Oct 18, 2026).
