What do plumbers charge per hour?
We could not find a published, verifiable price survey for San Diego County alone, so the figures below are national ranges. HomeGuide's 2026 plumber cost guide puts the typical plumber hourly rate at $45 to $150, with an average of $75 before trip fees and materials. It lists service call fees of $50 to $200, usually covering the first hour, and a flat fee of $200 to $250 for standard services or the first hour of work at companies that price that way. Treat these as a floor for coastal Southern California rather than a local quote, and ask each company how it bills before anyone arrives.
How much more do nights and weekends cost?
The same guide says weekend, after-hours and holiday work is commonly billed at double or triple time, and weekday nights at time and a half or more. It puts emergency work at roughly $125 to $170 per hour, and late-night rates at some companies at $195 to $260 per hour. If the problem can be contained by closing a valve, waiting for regular hours can cut the bill substantially. Our emergency plumber guide explains how to stop the water first.

What does a water heater replacement cost?
HomeGuide's water heater installation guide, updated January 2026, puts a standard tank water heater at $600 to $3,100 installed and a tankless unit at $1,400 to $5,600 installed, nationally. An expansion tank adds $100 to $400, and gas line or electrical permit fees run $50 to $200 in its national figures. In San Diego, also budget for seismic strapping, which state law requires on every water heater; our earthquake strapping guide explains the rules, and the water heater guide covers tank versus tankless.
What do City of San Diego plumbing permits cost?
Permit fees are one cost you can verify locally. The City of San Diego's Information Bulletin 103 sets plumbing permit fees per item. Selected residential figures:
| Permit item | City of San Diego fee |
|---|---|
| Water heater | $122.97 each |
| Water softener | $87.68 first, $52.39 each additional |
| Backflow preventer, domestic | $87.68 first, $52.39 each additional |
| Water or waste pipe repair or replacement, residential | $264.25 per dwelling unit |
| Gas system leak repair | $264.25 per 5 outlets |
Other cities in the county, such as Chula Vista, Escondido and Oceanside, set their own fees, so check with the local building department. A quote that leaves out the permit, or a contractor who suggests skipping it, is a warning sign.
How should you pay?
California law limits what a contractor can collect before work starts. CSLB's consumer guide Terms of Agreement says the down payment on a home improvement contract cannot exceed $1,000 or 10 percent of the contract price, whichever is less, with no exception for special order materials. Payments may not run ahead of the work completed, and any price change needs a written change order. Jobs over $500 in labor and materials need a written contract.
How do you compare quotes?
- Ask whether the price is flat rate or time and materials, and what the service call fee covers.
- Get the fixture or water heater brand and model in writing.
- Confirm who pulls the permit and whether the fee is included.
- Ask what happens if walls or slab need to be opened, and who patches them.
- Check the license number in the CSLB license check before you sign.
Our hiring guide covers the license check step by step.

Frequently asked questions
Why are there no San Diego-specific plumber prices here?
We only publish numbers we can source. National cost guides like HomeGuide publish ranges for the whole country, not San Diego County, and we found no verifiable local survey. Expect local quotes to vary, and use two or three written bids to see what the market in your part of the county actually charges.
How much is a water heater permit in San Diego?
In the City of San Diego, Information Bulletin 103 lists a residential water heater permit at $122.97 per heater. Cities like Chula Vista, Escondido, El Cajon and Oceanside have their own building departments and fee schedules, so ask the contractor which fee applies and whether it is included in the quote.
Can a plumber charge a large deposit for a water heater?
Not on a home improvement contract. CSLB says the down payment cannot exceed $1,000 or 10 percent of the contract price, whichever is less, and there is no exception for special order materials. Only contractors with a blanket performance and payment bond on file with CSLB may ask for more.
Is after-hours plumbing always more expensive?
Usually. HomeGuide's national guide says weekend, after-hours and holiday work is often billed at double or triple time, and weekday nights at time and a half or more. Shutting off the water and waiting for regular hours, when the problem allows it, is one of the easiest ways to lower the cost.
