Safety check
An inspector looks at gas connections, venting, strapping and relief valve discharge on your water heater. Those are the parts that matter most if something goes wrong.

Quick answer
In Newport Beach, a plumbing permit is required to replace or repair a water heater and to replace any fixture that breaks a trap seal, such as a sink, lavatory, toilet or garbage disposal. Replacing a washer, dryer, stove or built-in refrigerator does not need one. Water heater and sewer line replacement permits do not trigger the SB 407 rule to replace all older fixtures.

Which plumbing jobs need a permit in Newport Beach
The City's Building Division has a written plumbing code policy on direct replacements. A plumbing permit is required for all plumbing fixture replacements that need a trap seal to be broken, such as sinks, lavatories, water closets and garbage disposers. Water heater replacements also require a plumbing permit. Appliances like washers, dryers, stoves and built-in refrigerators do not need a permit when you replace them.
The City's water heater checklist goes further and says a permit is required for replacement or repair of water heaters, citing the California Plumbing Code.
| Work | Permit? | Notes |
|---|---|---|
| Water heater replacement or repair | Yes | Tank or tankless, gas or electric |
| Toilet replacement | Yes | Breaks a trap seal |
| Kitchen or bathroom sink replacement | Yes | Breaks a trap seal |
| Garbage disposal replacement | Yes | Named in the City policy |
| Whole-house repipe | Yes | The City publishes a copper repipe checklist |
| Sewer line replacement | Yes | Does not trigger SB 407 fixture upgrades |
| New or altered gas piping | Generally yes | Ask the Building Division about your scope |
| Washer, dryer, stove or built-in refrigerator replacement | No | Appliance swap only |
What the inspector checks on a water heater
The City publishes a water heater checklist based on the California Plumbing Code and California Mechanical Code. These are the items that most often decide whether an install passes.
- A full-bore, ball-type shutoff valve on the cold water supply
- Pipe unions within 12 inches of the unit
- Seismic bracing to the state standard
- For attic installs, access of at least 22 by 30 inches
- For attic installs, a light fixture and an electrical receptacle at the water heater
- Correct venting, gas connection and temperature and pressure relief discharge
The checklist says it is a general guide and does not cover every code requirement. Older installs often need small upgrades to pass, such as a new shutoff valve, new strapping, a drip pan or an expansion tank where the plumbing is a closed system. A good plumber prices those into the quote instead of surprising you after the inspection.
SB 407 and the low-flow fixture rule
California's SB 407 requires older, high-flow plumbing fixtures to be replaced with compliant low-flow fixtures in certain situations. Newport Beach applies it to residential building permits: for covered projects, every fixture in the dwelling unit must be replaced with fixtures that meet the maximum flow rates.
The City also lists permitted repairs that do not trigger SB 407. That list includes water heater replacement and sewer line replacement, along with electrical service change outs, HVAC change outs, reroofs, siding or stucco, site work, window replacement and other repairs as determined by the Building Official.
So a water heater swap or a sewer replacement will not force you to replace every toilet and showerhead in the house. A larger remodel or addition can. We tell you up front if your project is likely to trigger it.
How plumbing permits get pulled
Newport Beach runs an online permitting portal called CiViC, available 24 hours a day. It handles express permits for simple single-scope projects at single-family homes and duplexes, along with additions, remodels, pools, docks and solar. The City notes that express permits are not for remodels or projects that need multiple permits or plan review.
For most plumbing jobs, the licensed contractor doing the work applies for the permit, schedules the inspection and meets the inspector. If someone asks you to pull a permit in your own name for work they will do, ask why. An owner-builder permit puts the responsibility for the work on you.
Scope the job
The plumber confirms what needs replacing and whether a permit applies.
Permit is issued
The contractor applies with the City and posts or keeps the permit card on site.
Work is done to code
Strapping, valves, venting and connections are installed to the checklist.
Inspection
A City inspector checks the work. Corrections, if any, are fixed and reinspected.
Final
The permit is finaled and becomes part of the property's permit history.
How to look up a home's permit history
Before you buy, sell or hire a plumber for an older home, check what work was permitted.
The City keeps permit records in two places, depending on whether the work is finished:
- Completed work: the Archived Permit History by Address database on the City's ecms.newportbeachca.gov records site, in the BuildingPermits collection.
- Open permits: the City's Search for Open Permits by Address tool. It only covers activity since the Building Division started using its current permit software.
There is an important exception. Permits transferred from the County of Orange for Newport Coast, Bay Knolls and Santa Ana Heights are kept in a separate database that is not online. Those records have to be requested at the Building Division on the second floor of City Hall. The City links a Newport Coast Jurisdiction List to check whether an address was transferred.
Building plans are not posted online. Under California Health and Safety Code sections 19850 to 19853, copying plans requires permission from the property owner and any licensed architect or engineer who stamped them. The City also offers an optional Residential Building Records Report, often used when ownership transfers.
Permits for bigger plumbing jobs
Repipes
The City publishes a separate checklist for copper water line repipes. Among other items, it calls for structural members weakened by cutting or notching to be reinforced or replaced to meet the California Building Code, and for the water heater to be braced to the minimum state standard. In other words, a repipe inspection looks at how the walls and framing were left, not just at the pipe.
Sewer line replacement
Replacing a sewer lateral needs a permit, and the City lists it among the repairs that do not trigger SB 407. If the work reaches into the street or alley, or if your parcel is served by IRWD or Costa Mesa Sanitary District, that agency may have its own requirements. Costa Mesa Sanitary District, for example, requires a sewer plan for projects that rebuild a lateral and requires a contractor to video inspect an existing lateral that will be reused. Ask your sewer agency before work starts. Our who to call guide lists each agency.
Backwater valves
The California Plumbing Code requires a backwater valve for fixtures on a floor lower than the next upstream sewer manhole cover, and requires cleanouts on drains that pass through the valve to be labeled. Adding one to an existing home involves cutting into the lateral, so plan on a permit. See flood repairs and backwater valves.
What to do if you find unpermitted plumbing work
It is common to find a water heater or bathroom in an older Newport Beach home with no permit on file. That does not always mean the work is bad. It does mean nobody inspected it.
- Check the records first. Search both the archived permit history and the open permits tool. For Newport Coast, Bay Knolls and Santa Ana Heights, older county records have to be requested at the Building Division.
- Look at the safety items. On a water heater, check for seismic bracing, a relief valve line that runs to an approved location, a proper vent connection and a gas shutoff.
- Talk to the Building Division. Call (949) 644-3200 to ask how the City handles permitting existing work for your situation.
- Get a licensed plumber's opinion. A plumber can tell you what would need to change to pass an inspection today.
Why a permit is worth it
Clean records
Permit history follows the house. Buyers, inspectors and insurers can see that the work was done and finaled.
A contractor test
Licensed plumbers pull permits as a matter of routine. Someone offering to skip the permit to save you money is telling you something about how they work.
California also limits unlicensed work. Since January 1, 2025, the minor work exemption for unlicensed people is $1,000, and it does not apply to any job that needs a permit. Because water heater and fixture replacements need a permit in Newport Beach, they need a licensed contractor. Our license check guide explains how to verify one.
