Quick answer

Bathroom remodeling in Compton needs a City permit once fixtures or concealed pipes are replaced or moved, while tile, cabinets and counter tops sit on the City's exemption list. About half of Compton homes date from 1940 to 1959, so expect old plumbing, and a presale inspection can flag unpermitted bathroom work at sale.

Compton's bathrooms were mostly built for smaller households than the ones using them now. The City's Housing Element says half of all housing was built between 1940 and 1959 and that the average household has 4.17 people against 2.96 across Los Angeles County, so one hall bath often serves a crowd. The Census Bureau's 2024 estimates put 61.1 percent of the City's roughly 23,600 homes before 1960 and 44.6 percent of households as renters.

This page covers the presale inspection that follows a Compton house to market, what the old plumbing behind the tile tends to be, where the City's code draws the permit line, and how work hours and one-bath households shape a schedule. Prices, tub-to-shower options and the phase timeline are on our bathroom remodeling page, and the Compton overview lists the other trades we manage in the city.

Bathroom Remodeling rules in Compton

What Compton's code and Building and Safety forms say about bathroom work

Where bathroom remodeling permits come from in Compton: City of Compton Building and Safety Department.

  • The Chapter 15 plumbing exemptions cover stopping leaks and clearing stoppages and the removal and reinstallation of water closets when the repair does not replace or rearrange valves, pipes or fixtures. Replacing or relocating fixtures or concealed pipe is new work needing a permit. The City's amended exemption list also exempts tiling and cabinets.

Will a bathroom remodel pass Compton's presale inspection?

Compton is one of the cities that inspects a house before it changes hands. Municipal Code Sections 14-2.3 and 14-2.4 require a Report of Residential Building Records before a residential building is sold or exchanged, and the City's Form B-004 says the inspector looks at all interior and exterior space, including rooms, closets, garage and sheds. A bathroom redone without a permit can show up in that report as a correction.

The report is valid for six months. The buyer and seller then choose between a full compliance release, where every correction is finished and permits may be needed to legalize earlier work, and an AS-IS release that the buyer signs and has notarized. If violations are not handled within 30 days after closing, notices run up to 60 days and then a substandard notice goes on the property title. The report and the release carry their own City fees, so ask the department for the current figures.

The practical lesson is to pull the permit when the work calls for one, because a closed permit with a final inspection is the paper trail a future buyer's agent will ask about. Our guide to checking a contractor's license covers the other half, which is knowing who pulled it.

Older plumbing

Bathroom renovation in a 1940s or 1950s Compton bungalow: what is behind the tile?

Nobody can say until the wall is open, but the age of the housing sets the odds. The Housing Element notes that housing more than 30 years old typically needs major rehabilitation such as a new roof, foundation work and plumbing, and it names rehabilitation of the stock a priority need. A Compton hall bath from the 1950s may still have its original drain, a shower pan built decades ago and supply lines of the same era.

Two items deserve an answer before demolition. The U.S. Environmental Protection Agency's lead-safe renovation rule requires certified firms for paid work that disturbs paint in homes built before 1978, and the Census Bureau counts 77.8 percent of Compton's homes as built before 1980, so assume it applies unless the build year says otherwise. Then agree on a unit price for rotted subfloor or a failed drain line in the proposal, so a discovery changes the total by a known amount instead of starting an argument.

  • Can the firm show its EPA lead-safe certificate before demolition starts?
  • Will the subfloor around the toilet and the tub edge be opened and probed?
  • What per-unit price covers replacing soft framing or a failed drain line?

Permit line

Does a Compton bathroom remodel need a permit? What the City's exemption list says

We found no do-I-need-a-permit page on the City's site, so the answer comes from the amended Section 105.2 in Chapter 15 of the Municipal Code on ecode360. For a bathroom it exempts tiling, cabinets, counter tops and similar finish work, stopping leaks and clearing stoppages, and removing and reinstalling a water closet when no valves, pipes or fixtures are replaced or rearranged.

Replacing or relocating fixtures or concealed pipe is treated as new plumbing work needing a permit and an inspection. The list also says its exemptions never authorize work that violates a code, and as we read it, it does not address a tub-to-shower conversion or a new shower pan, so those are questions for Building and Safety at (310) 605-5509 rather than guesses. Form B-006 adds that electrical, plumbing and mechanical permits are required in addition to the building permit when they apply.

A permit has a clock. Under Section 105.5 it becomes invalid if work does not start within 365 days of issuance or is suspended or abandoned for 180 days, and the building official can grant written extensions of up to 180 days each.

How should a Compton shower be waterproofed, wired and vented?

Waterproofing is the layer behind the tile, not the tile itself. A rebuilt shower gets a sloped mortar bed or a foam pan, a continuous membrane lapped up the walls and over the curb, and a flood test with the drain plugged before any tile goes on. Ask for photographs of the test, because they are the record of what sits under the finish.

On the energy side, the City's residential plan check form (B-006) places Compton in Climate Zone 8 and lists Seismic Zone D with a 110 mph wind design. Bathroom exhaust and lighting rules live in Title 24, and the California Energy Commission's summary of the 2025 residential mandatory measures calls for demand-controlled or continuous local exhaust and a vacancy sensor on at least one bathroom light. Chapter 15 adopts the 2019 California codes by reference while the City's forms cite 2022 and 2025 editions, so we confirm with plan check which edition governs your permit before the fan and switches are specified.

Where does a family of five shower during a Compton bathroom remodel?

The Housing Element reports 21.6 percent of Compton households as overcrowded against 11.2 percent countywide, so a one-bath house with several people in it is common, and the weeks without a shower are a household problem rather than a footnote. Put the water shut-off days on a calendar, decide where everyone washes, and ask the plumber to restore water at the end of days when the work allows it.

Section 7-12.22 limits construction work to 7:00 a.m. to 7:00 p.m. Monday through Saturday, lists no Sunday hours, and allows an exception only for urgent necessity under a Building Official permit of no more than three days at a time. Permits are filed and inspections requested through the City's Citizen Serve portal, and Form B-016 says only a contractor or broker with an active City business license can use it. The Building and Safety Department page lists counter hours of Monday through Thursday, 7:00 a.m. to 6:00 p.m., with no Friday hours shown, so the rough plumbing inspection and the shower pan test are the dates to protect.

Rentals and permits

Bathroom remodeling in a Compton rental, and who may pull the permit

About 44.6 percent of Compton households rent, and 11.1 percent of homes sit in buildings of five or more units, so many bathroom jobs belong to a landlord. Form B-020 spells out who can apply. A contractor brings a state license card, photo ID, workers' compensation proof and a current Compton business license, and signs the application in person or sends an agent with a notarized authorization. An owner-builder brings a grant deed, photo ID and a current City business license, plus a rental license if the property is rented.

We found no Compton rule on tenant notice or temporary housing for plumbing work, and this page does not cover landlord and tenant law, so check state law and ask the City before demolition. For a unit with one bathroom, agree in writing which days it is out of service and who provides an alternative.

As MDG Builders, CSLB #1040337, we design, permit and supervise, while the plumber, tile setter and electrician are licensed specialty subcontractors whose license numbers and certificates of insurance are yours on request. Our post on how general contractors use subcontractors shows how the crews, the permit and the contract fit together.

Fee schedules and forms change, so ask the counter for the version in force on the day you file.

What bathroom remodeling costs around Compton

Our bathroom remodeling page puts a refresh at about $9,000 to $18,000, a mid-range remodel with the same layout at $25,000 to $40,000, and a primary or upscale bath at $50,000 to $85,000 and up. Those tiers lean on Remodeling magazine's 2025 Cost vs. Value report for Los Angeles, which lists a midrange bath remodel at $27,143, because no Compton price study turned up, and the bathroom cost guide names every source. We found no building permit fee schedule for Compton, so no permit amount is printed here. Nearby Carson, Lynwood, Paramount and Gardena run their own building departments and have no page here yet, but you can compare how Long Beach, Downey and Los Angeles handle the same job. Households that outgrow one bath often look next at a room addition, an ADU or new windows.

FAQ

Compton bathroom remodel questions, answered

Do I need a permit to remodel a bathroom in Compton?

Usually yes once fixtures or concealed pipes are replaced or moved. Compton's amended exemption list covers tiling, cabinets, counter tops, stopping leaks and clearing stoppages, but replacing or relocating fixtures or concealed pipe is new plumbing work needing a permit and inspection. The City has no plain permit page, so confirm your scope with Building and Safety at (310) 605-5509.

Do I need a permit to change a toilet in Compton?

Often no for a plain swap, but confirm it. The exemption list covers removing and reinstalling a water closet when no valves, pipes or fixtures are replaced or rearranged, which a like-for-like swap on the existing connection may fit. A new toilet location or new pipe is plumbing work that needs a permit. Call the department before the plumber books a day.

How much does a bathroom remodel cost in Compton, California?

Plan on about $9,000 to $18,000 for a refresh and $25,000 to $40,000 for a mid-range remodel in the same layout, with a primary or upscale bath from about $50,000 to $85,000 and up. These are Los Angeles based figures because we found no Compton study. Hidden framing or pipe repair is priced per unit so a surprise changes the total by a known amount.

How much is a permit to remodel a bathroom in Compton?

We could not verify a figure, so we print none. We found a published Planning fee schedule but no building permit fee schedule for Compton, and the City's forms say plumbing, electrical and mechanical permits can be required in addition to the building permit. Ask the counter for the amounts that apply to your scope, and put them in the written proposal.

How long does a bathroom remodel take in Compton?

Plan on about two to six weeks for design and selections, then roughly three to six weeks on site, plus the permit wait. Demolition and rough plumbing, waterproofing and curing, tile and fixtures, and the shower glass fill that time. Long-lead tile and glass usually cause more delay than the crew does.

Where do you shower when your only bathroom is being remodeled?

Borrow a second bathroom, a gym membership or a relative's shower, since the room cannot be used for weeks. The water stays off from demolition until the new shower is tiled and sealed. With Compton's average household of 4.17 people, a written calendar of shut-off days matters, and a missed inspection can add days since the counter keeps Monday to Thursday hours.

Can a handyman do a bathroom remodel in Compton?

Only for very small jobs. California caps unlicensed minor work at $1,000 in total, counting labor and materials, and the cap does not apply once a permit is needed. Compton permit applicants must be a licensed contractor with a City business license or an owner-builder who signs in person. Look up any license on the CSLB website before paying a deposit.

Is a bathroom renovation worth it in Compton?

Usually at mid-range, less so at the top end. Remodeling magazine's 2025 Cost vs. Value report for Los Angeles shows a midrange bath recouping about 89.6 percent at resale and an upscale one about 42.3 percent. Those are Los Angeles figures, and Compton's presale inspection means permitted work is easier to sell than unpermitted work.

Should I test for lead before a bathroom renovation in an older Compton house?

A test helps, but the rule applies either way. Federal rules require a certified, lead-safe firm for paid work that disturbs paint in homes built before 1978, and about 77.8 percent of Compton's homes predate 1980. Ask for the firm's certificate and a dust containment plan before demolition starts.

What hours can a bathroom contractor work in Compton?

Section 7-12.22 allows construction work from 7:00 a.m. to 7:00 p.m. Monday through Saturday and lists no Sunday hours. The only exception is urgent necessity under a Building Official permit of no more than three days at a time. A condo or HOA may set stricter hours, so ask the management office before booking trades.
