# Selling a trades business in the San Francisco Bay Area

> Selling an HVAC, plumbing, or electrical business in the nine-county Bay Area: the same 3×–10× multiples as the rest of the country, but shaped by a mandated heat-pump conversion wave beginning in 2027, California's taxation of capital gains as ordinary income, and CSLB licensing that does not transfer with the business.

## Key facts

- **California capital-gains treatment:** Taxed as ordinary income, up to 13.3% — on top of federal long-term capital gains up to 20% plus the 3.8% net investment income tax
- **Gas water heaters banned from sale:** January 2027
- **Gas furnaces banned from sale:** January 2029
- **CSLB license threshold:** $1,000 per job

## What is different about the Bay Area

Bay Area home-services businesses are valued on the same multiples as the rest
of the country — roughly 3× to 10× earnings — but higher ticket sizes and an
affluent customer base often mean stronger absolute earnings to apply them to.
Three local factors change the picture materially.

## The 2027–2031 electrification wave

The Bay Area Air District's zero-NOx rules effectively mandate heat-pump
replacements across most of the nine-county region:

- **Jan 2027: Gas water heaters banned from sale** — Residential tank water heaters (under 75,000 BTU/hr) must be zero-NOx — in practice, heat-pump electric.
- **Jan 2029: Gas furnaces banned from sale** — New residential and commercial furnaces must be zero-NOx. The big one for HVAC: a mandated shift to heat pumps.
- **Jan 2031: Larger commercial water heaters** — Commercial and multifamily units (75,000 BTU/hr to 2M) follow. Existing, working appliances are never force-replaced.

Existing, working appliances are never force-replaced; the rules govern new
sales and installations. For HVAC, plumbing, and electrical owners this is a
structural, government-backed demand tailwind, and buyers pay up for businesses
with the technician training and track record to capture it.

## California taxes

California has no special capital-gains rate — it taxes capital gains as
ordinary income at rates up to 13.3%. Combined with federal long-term
capital-gains tax and the net investment income tax, a large Bay Area sale can
face a combined rate well north of 30%. Structure and timing matter more here
than almost anywhere.

## CSLB licensing

California contractor licenses (C-20 HVAC, C-10 electrical, C-36 plumbing, and
others) attach to a qualifying individual, not to the business, and do not
transfer automatically. A sole qualifier who leaves at closing can leave the
buyer unable to operate legally the next day, so qualifying a backup early
protects the deal.

## Common questions

### How much is my Bay Area trades business worth?

Bay Area home-services businesses are valued on the same multiples as the rest of the country — roughly 3× to 10× earnings depending on trade, size, recurring revenue, and owner dependency — but the region's high ticket sizes and affluent customer base often mean stronger absolute earnings to apply them to. The biggest local swing factor right now is electrification readiness: HVAC, plumbing, and electrical businesses positioned for the heat-pump transition are selling into a mandated, multi-year demand wave. Use the estimator on this page for a starting range, then get a specific number from a buyer who understands the California market.

### Do the 2027 Bay Area gas-appliance rules affect my sale?

They can help it meaningfully. The Bay Area Air District's zero-NOx rules phase gas water heaters out of sale starting January 2027 and gas furnaces starting January 2029, effectively mandating heat-pump replacements across most of the nine-county region. For an HVAC, plumbing, or electrical owner, that's a structural, government-backed demand tailwind — and buyers pay up for businesses with the technician training, supplier relationships, and electrification track record to capture it. The rules apply to new installations, not forced removal of working appliances.

### How does California tax the sale of my business?

This is the single biggest local difference, and it's not in your favor: California does not have a special capital-gains rate — it taxes capital gains as ordinary income, at rates up to 13.3%. Stack that on federal long-term capital-gains tax (up to 20%) plus the 3.8% net investment income tax, and a large Bay Area sale can face a combined rate well north of 30%. Deal structure, timing, and planning matter more here than almost anywhere. Talk to an M&A-experienced California CPA before you sign — it routinely saves far more than it costs. Nothing here is tax advice.

### What happens to my CSLB license when I sell?

California contractor licenses (C-20 HVAC, C-10 electrical, C-36 plumbing, and so on) are tied to a qualifying individual (an RMO or RME) and don't automatically transfer with the business. If you're the sole qualifier, a buyer can't legally operate the day after closing — so qualifying a backup, or planning the license transition early, protects your deal. Note California now requires a license for any job of $1,000 or more, and several classifications have continuing-education requirements at renewal.

### Do you buy trades businesses across the whole Bay Area?

Yes — from San Francisco and the Peninsula through the South Bay and Silicon Valley, across the East Bay from Oakland to Livermore and Concord, and up into the North Bay in Marin, Sonoma, Napa, and Solano. We're long-term operators, not brokers or flippers: we buy good Bay Area trades businesses and keep running them, with the crew and the name intact. A first conversation is free and carries no obligation.
