Bathroom Remodelingin Redondo Beach, CA
Bathroom remodeling in Redondo Beach needs a City permit once walls, plumbing, electrical or ventilation change, and a homeowner cannot pull a permit on a job valued over $50,000. With 67.4 percent of homes built before 1980 and a third of units in buildings of five or more, expect hidden pipes and association approvals.
Redondo Beach was a resort town before it was a suburb. Hotel Redondo opened in 1890, voters chose cityhood in 1892, and the population climbed from 13,092 in 1940 to 54,772 in 1965. The 2024 American Community Survey puts the median home at a 1973 build year, so the typical bathroom here is about half a century old.
This page covers who has to approve a condo or rental bath, what sits behind 1970s tile, how the 2025 codes treat ventilation, where a permit starts and stops, what the Coastal Zone adds near the water, and when a bath becomes an addition. Price tiers and the phase timeline are on our bathroom remodeling page, and the rest of our work in the city is on the Redondo Beach overview.
What Redondo Beach Building and Safety says about bathroom work
Where bathroom remodeling permits come from in Redondo Beach: City of Redondo Beach Community Development Department, Building and Safety Division.
- A bathroom remodel that alters walls, plumbing, electrical or ventilation needs a permit under RBMC 9-1.02, with plumbing permits under the City's Plumbing Code chapter (RBMC Title 9, Chapter 5) and electrical permits under Chapter 3.
- The City deleted its local 'light, ventilation, and sanitation' section (RBMC 9-1.07 was repealed), so bathroom ventilation and sanitation requirements come from the state codes as adopted in RBMC 9-1.01 and 9-22.01, while the residential remodel valuation is 65 percent of new construction cost (RBMC 9-1.03).
- The county charges sewer connection fees when sewer demand increases, such as adding a building or changing use (Construction Project Resource Guide), which can apply when a bathroom addition comes with new dwelling space or an ADU.
- The forms page lists a Los Angeles County lead poisoning prevention handout, which is the handout to ask for when demolishing old bathroom finishes (9.9 percent of Redondo Beach housing units were built in 1949 or earlier), but the PDF was not read.
- A JADU created inside a single-family home must have exterior access independent of the existing dwelling and be no larger than 500 square feet, which governs a bathroom added as part of a JADU (RBMC 10-2.1506(b)(2)).
Bathroom renovation in a Redondo Beach condo or rental: who approves it first?
Redondo Beach is not mostly single-family houses. The 2024 census survey counts 40.0 percent of its 30,753 housing units as detached homes, 32.5 percent as units in buildings of five or more, and 46.6 percent of households as renters. A bath job here often starts with a management office or a landlord, and only then with the City.
Three approvals tend to stack. The association or owner signs off on scope and work days, the City permit covers plumbing, electrical and any wall changes, and the contractor needs a City business license before a permit issues. The City also says a homeowner cannot pull a permit for a project valued over $50,000 or one involving two or more units, so a contractor of record is the usual route.
Get the building's rules in writing before demolition: elevator or stair access, dumpster location, water shut-off notice and quiet hours. They can be tighter than the City's hours, and they decide whether a three-week job is realistic.
- Does the association want a plan set, a certificate of insurance or a deposit?
- Which days can water be shut off for the stack, and who warns neighbors?
- Does a tenant live in the unit, and where do they shower?
What is behind the tile in a 1960s or 1970s Redondo Beach bathroom?
The largest share of the City's housing, 25.2 percent, went up in the 1970s, with 16.7 percent in the 1960s and 15.5 percent in the 1950s, so 67.4 percent of units predate 1980. Nobody sees the supply lines, the drain or the subfloor until demolition, which is why a quote for an older bath should say what happens when something turns up.
A rebuilt shower is a system: a sloped pan, backer board and one continuous membrane that runs up the walls and over the curb, flood tested before tile. Soft framing at the tub or the toilet flange is replaced at a unit price agreed in the proposal. In a house built before 1978, federal EPA rules require lead-safe practices when paid firms disturb paint, and the Building Division's forms page lists a Los Angeles County lead poisoning handout worth asking for.
Older still is the Original Townsite in South Redondo, a National Register district where houses and small apartment buildings date from the 1890s to the 1930s. On a landmark, an interior feature identified at designation can need a Certificate of Appropriateness to alter, so ask Planning what was recorded for your house before the tile comes off.
- Is the subfloor around the toilet opened and inspected?
- Is the membrane named, and is the flood test photographed?
- What unit price applies to rotted framing or an old drain line?
Bathroom ventilation under the 2025 codes: what a Redondo Beach inspector expects
Redondo Beach repealed its own light, ventilation and sanitation section, RBMC 9-1.07, so ventilation comes from the state codes the City adopted, and the 2025 California Building Standards Code applies to every submittal from January 1, 2026. The Energy Commission's mandatory measures for 2025 call for local mechanical exhaust in a bathroom, demand controlled or continuous, and at least one bath light on an occupancy or vacancy sensor that shuts off automatically.
Moisture is a design problem here, not only a code item. The nearest NOAA station records 13.76 inches of rain a year and an average high of 70.6 F, and the coast and the salt air matter more to construction than the weather does. A mild climate still does not clear steam from a small room, so a fan sized for the room and ducted outside is the cheapest protection for new tile and paint.
Ask that the fan be named in the permit scope with its duct run to the exterior, and that the light switching be shown on the plans. A duct that ends in an attic collects moisture above the ceiling, and repairing that costs more than the fan.
Do you need a permit for a bathroom remodel in Redondo Beach? Where the line sits
RBMC 9-1.02 requires a permit to alter, repair or improve a building, with plumbing permits under Title 9 Chapter 5 and electrical permits under Chapter 3. A bath that changes walls, moves a drain, adds a circuit or alters ventilation is permit work. The City amended only three items of the state exempt list, so for plain swaps such as a toilet, a vanity or tile we found no Redondo Beach page saying exempt. Ask Building and Safety at (310) 318-0636 before the plumber books a day.
Applications go through the City's iWorQ portal, with Planning stamping the plans first when the job needs it. The City lists a first building review of up to three to four weeks, and small projects with enough detail are typically processed in one to two business days. Work before the permit issues costs double the permit fees, and a residential remodel is valued at 65 percent of new construction cost for fee purposes. Start at the Building and Safety Division page.
MDG Builders, CSLB #1040337, is a general contractor: we write the scope, pull the permits and run the schedule, and the plumber, tile setter and electrician are licensed specialty subcontractors whose license numbers and insurance certificates you can ask to see. For who answers to whom on site, see how general contractors use subcontractors.
Permit expiry has two answers in the City code: RBMC 9-1.06 says 12 months without a start, while RBMC 9-22.05.4 still says 180 days, so ask which one is printed on your permit.
Bathroom remodel near the water: does the Coastal Zone need a Coastal Development Permit?
Redondo Beach runs its own certified Local Coastal Program and issues its own Coastal Development Permits, which sets it apart from neighbors: the Coastal Commission's December 2019 report listed Hermosa Beach and Torrance as not certified. A sample of 178 points across the city, tested against a state copy of the 1977 boundary, put about 16 percent of the land in the Coastal Zone, along the western shoreline. That is a sample, and the City's map decides any address.
For a bath the news is mostly good. Improvements to an existing single-family home are exempt under RBMC 10-5.2208, and repair and maintenance that does not enlarge a structure is exempt too. The exemption narrows on a lot between the sea and the first public road, or within 300 feet of a beach, when a project adds 10 percent or more floor area, a story or height. A bath bump-out can cross that line, and so can replacing half or more of a residential structure.
Nobody should decide this alone. Anyone claiming an exemption must first get a determination from the Community Development Director, under RBMC 10-5.2206(b), and unpermitted coastal work blocks new applications until a permit covers it as well. Ask for the determination in writing.
Adding a second bathroom or half bath: when a bath turns into an addition
A new bathroom carved from a closet or hallway is a remodel. A new room built out from the house is an addition, and the City counts it that way. Any addition over 500 square feet of combined floor area, and any addition above the first story, goes through Administrative Design Review by the Community Development Director before Building and Safety takes plans.
Small bump-outs have limits of their own. A home on a narrow lot with nonconforming setbacks can be altered but not enlarged past today's zone rules under RBMC 10-2.2004, and an addition of 1,200 square feet or more triggers sprinklers throughout an existing house. The county also charges sewer connection fees when demand rises, which can apply when a bath comes with new living space.
A bath inside a junior ADU has its own size cap: a junior unit in a single-family home is limited to 500 square feet and needs its own exterior entry. If a second bath is the first step toward a backyard unit, read our pages on ADU construction in Redondo Beach and the room addition in Redondo Beach before anyone draws.
Where do you shower? Redondo Beach work hours and inspection days
Construction is allowed Monday to Friday from 7 a.m. to 6 p.m. and Saturday from 9 a.m. to 5 p.m., never on Sundays or on six holidays, under RBMC 9-1.12. The rule carves out minor repairs and routine maintenance of homes, but a gutted bath with a tile saw and a dumpster is better planned as regular construction.
Inspections are requested in the portal by 3 p.m. for next-day service, run Monday to Thursday and on alternating Fridays, and inspectors leave for the field at 8:30 a.m. The rough plumbing inspection and the shower flood test must pass before tile covers anything, and stamped plans of at least 24 by 36 inches must be on site. Because City Hall closes every other Friday, the calendar has fewer inspection days than the work week, so book the plumbing visit early in the week.
In a one-bath house the calendar is the project. Write down the days the water is off, where the household showers and what a tenant gets, if there is one. With 46.6 percent of households renting, that written plan is routine in this city.
Condo and rental buildings often add their own hours and elevator rules on top of the City's, so confirm them before booking trades.

What bathroom remodeling costs around Redondo Beach
On our bathroom remodeling page the regional tiers run about $9,000 to $18,000 for a refresh, $25,000 to $40,000 for a midrange remodel in the same layout and $50,000 to $85,000 and up for a primary bath, based mainly on Remodeling magazine's 2025 Cost vs. Value report for Los Angeles. We found no Redondo Beach cost survey with a stated method, and one local contractor page that lists $19,260 to $42,800 for a 100 square foot bath has tiers that do not reconcile with its own per square foot rates, so we rate it low. Permit fees follow the City's valuation, not your contract, and are not priced here. The bathroom remodel cost guide lists the sources. A new bath window leads to window replacement in Redondo Beach, and a bath in a backyard unit to ADU construction in Redondo Beach.

| What it covers | Typical range |
|---|---|
| Refresh in the same layout: new vanity, toilet, fixtures, lighting, paint, limited tile | $9,000 to $18,000 |

Bathroom remodel permit, condo and Coastal Zone questions for Redondo Beach homes
Do I need a permit for a bathroom remodel in Redondo Beach?
Yes, once walls, plumbing, electrical or ventilation change. RBMC 9-1.02 requires a permit to alter or improve a building, with plumbing and electrical permits under their own chapters. We found no Redondo Beach page that lists tile, vanity or toilet swaps as exempt, so call Building and Safety at (310) 318-0636 before work starts. Starting without a permit costs double the permit fees.
Do I need a permit to change a toilet in my home?
Ask first, because we found no City page that exempts it. The City amended only three items of the state exempt list, and the rest of that list was not available to us. A like-for-like swap may be treated differently from one that moves the flange or adds a valve. Phone Building and Safety and tell them what the plumber will actually touch.
How much does a bathroom remodel cost in Redondo Beach?
Regional ranges run about $9,000 to $18,000 for a refresh, $25,000 to $40,000 for a midrange remodel and $50,000 to $85,000 and up for a primary bath, anchored on Remodeling magazine's 2025 Cost vs. Value report for Los Angeles. We found no Redondo Beach survey with a stated method, so a written proposal for your bath is the real price.
How long does a bathroom remodeling take?
Permit review can outlast the build. The City lists up to three to four weeks for a first building review, and small, complete projects are typically processed in one to two business days. The shower flood test must pass before tile goes on. Put the phases and the days the room is out of use into the proposal.
Where do I shower during a bathroom remodel in a one-bath house?
Make that a written plan before demolition. Agree which days the toilet and shower are out and where the household washes, whether a gym, a relative or a rental. Redondo Beach work hours, 7 a.m. to 6 p.m. on weekdays and 9 a.m. to 5 p.m. on Saturdays with no Sundays, set how many working days the room is down.
Does a bathroom remodel in the Redondo Beach Coastal Zone need a Coastal Development Permit?
Usually not for work inside an existing single-family home, but the City decides, not you. Improvements to an existing home and repair that does not enlarge it are exempt, with limits near the beach for added floor area, stories or height. Ask the Community Development Director for an exemption determination before the building permit.
Do I need a general contractor or a license to remodel a bathroom?
For work over $1,000 you need a licensed contractor, because California's unlicensed minor-work limit is $1,000 and the exemption is void when a permit is required. Bath work calls on plumbing (C-36), electrical (C-10) and tile (C-54) classifications. In Redondo Beach contractors also need a City business license, and homeowners cannot pull permits over $50,000.
Is a bathroom renovation different from a bathroom remodel for the permit?
No, because the City looks at what changes, not the word. A renovation that refreshes finishes in place and a remodel that moves fixtures both need a permit once plumbing, electrical, walls or ventilation change. The practical difference is scope: a renovation keeps the layout, and a moved drain or wall is the line to price carefully.
