What the County requires
The Building Permits & Inspection Division's FAQ (read 23 October 2026) lists "Water Heater" among typical projects that need a permit, and "Residential water heater" among permits that "can be automatically issued online". The County's residential exempt list (GI-21) exempts some water tanks on grade but says in brackets "not including water heaters".
| Water heater job | County rule |
|---|---|
| Like-for-like tank replacement | Permit required; issued online on payment |
| Tankless or heat-pump water heater | The online list does not separate them; a new gas line or circuit is separate list work ("Gas Line", "Electrical panel, circuit") |
| Solar water heater | Its own inspection code, 351 |
| New gas line to the heater | "Gas Line" is separately on the permit-required list |
This covers unincorporated areas only; Elk Grove, Citrus Heights, Rancho Cordova and the City of Sacramento issue their own permits.
Who can pull it
A CSLB-licensed plumber. California's plumbing classification is C-36 (CSLB Licensing Classifications); check it on Check a License. 86.6% of the 365 firms on County water heater permits matched an active CSLB license by name. Many of the busiest filers are HVAC and home-service companies, not plumbing shops; the license classification on CSLB tells you what they are licensed to do.
You, as an owner-builder, after signing the County's AP-16 notice; you become "the responsible party of record on the permit".
How to apply and get it inspected
- Apply and pay in Accela Citizen Access; the permit issues automatically.
- Install, then book code 350 Water Heater online, on 916-875-5296 or by text to 855-280-5383, by 5 p.m. for the next day (Scheduling Inspections).
- If gas piping changed, codes 347 Gas Piping and 352 Gas Pressure Test apply; the County's list notes 352 and 353 Gas Tag "are auto added together".
- Final: 399 Final Plumbing. Keep the signed job card; the FAQ says it is the Certificate of Occupancy for home projects.
Why so many water heater permits stay open
Water heater permits are the ones most often left without a final in the County: 71.7% finaled, against 84.1% for HVAC and 88.1% for roofing. The job takes a few hours and the crew leaves; nobody comes back for the inspection unless the firm books it.
| Measure | Sacramento County water heaters |
|---|---|
| Permits on homes, October 2023 to September 2026 | 3,553 |
| Firms | 365 |
| Firms with a permit in the last 12 months of the file | 211 |
| Usual filed value | $3,695 |
| Middle half of firms' usual value | $2,385 to $4,500 |
| Finaled (permits a year or more old) | 71.7% |
| Usual days from issue to final | 38 |
| 10th / 90th-percentile firm (10+ permits) | 45.0% / 91.6% |
| Busy firms under 70% finaled | 11 of 39 |
| Busiest / quietest month | February (index 137) / November (80) |
The spread between firms is wide: the 10th-percentile busy firm finaled 45.0% and the 90th 91.6%. The five busiest firms hold 44.6% of permits, so which one you call matters. Filings peak in February, when old tanks give out in the cold. Before the last payment, ask when the 350 inspection is booked; an open permit can surface when you sell.

What this does not tell you
Firms with under a year of permits show no finished share yet, so a new busy filer may look better or worse later. The County publishes no water heater fee on its building pages; Accela shows it before you pay. Swaps done without a permit are not in our numbers.
How we know this
Permit rules, the online-issue list, the exempt list and inspection codes are quoted from Sacramento County Building Permits & Inspection Division pages and its GI-21 and AP-16 documents, read 23 October 2026. Counts are Sacramento County permits on homes in unincorporated areas classified as water heater work, October 2023 to September 2026; "finaled" uses permits a year or more old, and days are issue to final.
Numbers come from Sacramento County building permits on single-family, duplex and townhouse homes in the unincorporated county (the County's Accela permit layer), data through October 18, 2026. Nobody paid to be on this page and nobody can.
