What Can a Handyman Do in San Francisco, California?

In San Francisco (San Francisco County), most “handyman” work is regulated at the STATE level through California’s Contractors State License Board (CSLB). California has a narrow handyman exemption for jobs where the TOTAL price is $500 or less (labor + materials); above that amount—or if you split a larger job into smaller invoices—you generally need a CSLB contractor license. Separately, San Francisco requires a local business registration (Business Registration Certificate) and you may still need building permits for many common repairs even if you’re under the $500 exemption.

In CA, jobs under $500 typically don't require a contractor license. Always verify with your local licensing authority.

✅ What You Can Do Without a License

Jobs $500 or less total (labor + materials) when the work would otherwise be “contracting,” as long as you do NOT split a larger project into smaller invoices
Interior painting and touch-up painting (where no lead abatement licensing is triggered and permits aren’t required)
Minor drywall patching/repair and interior trim/baseboard repairs (non-structural)
Hanging pictures, shelves, curtain rods, TV mounts (non-structural mounting; avoid cutting into fire-rated assemblies in multifamily without approvals)
Replacing door hardware (knobs, deadbolts), installing weatherstripping, minor door adjustments
Basic caulking and grout repair; replacing showerheads/faucet aerators (if no plumbing alterations and local permit rules aren’t triggered)
Assembling prefabricated furniture, installing blinds, baby gates, and other non-permanent fixtures
Yard cleanup and minor exterior maintenance not involving structural work (note: some tree work can be separately regulated/insured)

⚠️ What Requires a License

Any job where the total contract price exceeds $500 (labor + materials), if the work is in a CSLB-regulated classification (most construction trades)
Electrical contracting (e.g., running new circuits, panel work, significant rewiring) — typically requires CSLB C-10 for the contractor
Plumbing contracting beyond trivial fixture swaps (e.g., moving supply/drain lines, water heater replacement often triggers permits) — typically requires CSLB C-36
HVAC system installation/repair/ducting beyond minor thermostat swaps — typically requires CSLB C-20; refrigerant handling requires EPA 608-certified technicians
Structural work (framing changes, shear walls, foundations), roofing, window/door replacements that affect structure or egress—typically require CSLB licensure and building permits
Fire/life-safety system work (sprinklers, fire alarms) and many multifamily/common-area repairs—often require specialized licensing and permits
Permitted work where the permit applicant must be a licensed contractor (common on electrical/plumbing/mechanical permits depending on scope and SF DBI rules)
Advertising/contracting as a licensed contractor when you are not licensed (misrepresentation can trigger CSLB enforcement)

State Licensing Rules (CA)

Even when exempt from CSLB licensure, you must still follow permitting laws and other regulations (building permits, lead-safe rules, OSHA, etc.). If the job is over $500 total, a CSLB license is generally required for contracting. Advertising as a contractor for work over the exemption can also trigger CSLB issues.

Permit vs. Contractor License — What's the Difference?

A contractor LICENSE (CSLB) is a state credential to legally contract for and perform construction work above the handyman exemption and within regulated trades. A PERMIT is project-specific approval (usually issued by the local building department) to ensure code compliance for a particular job. You can be exempt from CSLB licensing and still need a city permit/inspection for the work.

Important Notes for San Francisco, California Handymen

CSLB enforcement in California is active: the $500 threshold is strict and includes materials; splitting contracts to stay under $500 is prohibited.
Insurance is not a substitute for licensing, but it is critical: carry general liability; if you have employees, workers’ compensation insurance is required by California law (and CSLB has workers’ comp rules for licensees).
Permits/inspections are common in San Francisco, especially in multifamily buildings; doing unpermitted work can lead to stop-work orders, fines, and difficulty getting paid.
If you sell/install taxable products (some materials), you may need California CDTFA registration; if you hire helpers, you may need EDD employer registration.
If working in older housing, lead-based paint rules may apply (federal EPA RRP requirements for pre-1978 housing when disturbing painted surfaces).

Your Next Steps to Operating Legally in San Francisco

Step 1: Decide if you will stay strictly under the $500/job exemption or pursue a CSLB contractor license for larger projects
Step 2: Register your business entity (LLC recommended) with the CA Secretary of State (LLC filing fee $70) and file the Statement of Information ($20)
Step 3: Register your business with San Francisco (Business Registration Certificate through the Treasurer & Tax Collector; fee varies by gross receipts)
Step 4: Obtain general liability insurance; if you will have employees, set up workers’ comp and EDD employer accounts
Step 5: If you need CSLB licensure, prepare for application ($450) + initial license fee ($200) + required bond ($25,000) and testing/qualifying steps
