How to Find the Best General Contractor in San Francisco
By SolidBay Construction SF | Updated 2026
San Francisco has thousands of contractors — ranging from exceptional to outright fraudulent. Here's how to find the right one for your project.
What to Look For
- Valid California CSLB license — verify at cslb.ca.gov
- General liability insurance ($1M+ per occurrence)
- Workers' compensation insurance
- Experience with SF permits and DBI inspections
- SF project references you can actually call
- Detailed written contracts with itemized scope
Red Flags to Avoid
- Asking for more than 10% or $1,000 as a deposit (illegal in California)
- No physical address or verifiable license
- Pushing to skip permits
- Vague contracts without itemized scope
- No insurance certificates
- Pressure to decide immediately
Why In-House Teams Matter in SF
SF's complex permitting environment means your contractor needs more than construction skills. A firm with in-house architects, structural engineers, and a permit expeditor saves significant time and money.
Questions to Ask Before Hiring
- How many SF projects have you completed in the last 2 years?
- Who pulls the permits — you or a subcontractor?
- Do you have an in-house expeditor?
- Can I speak with 3 recent SF clients?
- What's your process when unexpected conditions arise?
