Bathroom Remodelingin San Bernardino, CA
Bathroom remodeling in San Bernardino needs a City permit when the job touches plumbing, wiring, framing or ventilation, while tile, paint, cabinets and countertops need none by themselves. About 62.6 percent of the city's homes predate 1980, so lead and asbestos questions come first. Plan check is in person at 201 North E Street.
San Bernardino's bathrooms are mostly older than the people remodeling them. The Census Bureau's 2024 one-year estimates count 68,594 homes here, and about 62.6 percent were built before 1980. The City's history page describes a Mormon colony buying the rancho in 1851 and a Santa Fe rail link in 1886 that carried the population from 6,150 in 1900 to 12,779 in 1910. The Housing Element credits railroad work, Norton Air Force Base and Kaiser Steel in Fontana for the postwar tracts in north central San Bernardino and Del Rosa. The median owner-occupied home is worth $461,400, plus or minus $16,338.
This page covers what needs a permit, what old walls can hold, rentals and multi-unit buildings, the foothill rules that reach vents and windows, historic questions and the schedule. Where we quote Municipal Code text, we read it in GoCodebook's third-party mirror because the City's code host blocked our tools, so confirm each rule with the Building & Safety Division. Price tiers are on our bathroom remodeling page, and the San Bernardino area page lists every trade we cover here.
What the San Bernardino permit counter looks at in a bathroom job
Where bathroom remodeling permits come from in San Bernardino: City of San Bernardino Community Development & Housing Department, Building & Safety Division.
- A bathroom remodel that only swaps finishes (tile, paint, cabinets, countertops) is permit-exempt, while plumbing and electrical work needs a permit (the City's Mechanical, Electrical or Plumbing Permit Application covers projects with only those trades) and structural changes need a building permit with plans; contractors need a state license and a current City business license.
Sources for these rules
What is behind the walls of a San Bernardino bathroom built before 1980?
Probably the original plumbing and plenty of old paint. The 2024 Census table counts 14,038 homes from the 1950s, 8,772 from the 1960s and 8,849 from the 1970s, and about 9 percent of all homes, 6,480, date from 1939 or earlier. The Housing Element adds that at least half of the stock is 50 years old or more, and City staff estimate that 7 to 10 percent of homes need major repair and up to 20 percent moderate repair. We found no City or state source that dates pipe or wiring types by decade, so nobody can say what your wall holds until it is open.
Two rules have firm dates. Federal lead rules cover any paid job that disturbs painted surfaces in a house built before 1978, and the Census table cannot split 1978 from 1979, so your own build year decides. South Coast AQMD Rule 1403 sets work practices for asbestos in renovation and demolition, and it treats a house differently from an apartment or condominium. Old floor tile, adhesive and wallboard are the usual suspects, which is why sampling comes before demolition.
- Is the firm EPA lead-safe certified when the house predates 1978?
- Who samples old tile adhesive and wallboard before anything is torn out?
- Who runs a camera through the drain before the floor is closed?
Do I need a permit for a bathroom remodel or renovation in San Bernardino?
Yes, once the work goes past finishes. The City's exempt list covers painting, tiling, carpeting, cabinets and countertops, and the City says the electrical, plumbing and structural work around them is not exempt. A new vanity and countertop are finish work. Moving a drain, turning a tub into a shower, adding a circuit or changing a wall is permit work, and a job that is only plumbing, electrical or mechanical can use the City's own Mechanical, Electrical or Plumbing Permit Application.
Plan check happens at the counter. The City does not take plans by mail, courier or email, and it accepts emailed permit applications only for single-family electrical re-wires, water re-pipes, panel upgrades and re-roofs, so a bath with a moved drain goes in person to 201 North E Street. A contractor must show a state license and a current City business license, and a homeowner may pull their own permit only when they live in the house and do the work personally. The City publishes no plan-check turnaround on the pages we read, so we do not promise one.
State law draws another line. AB 2622 lets an unlicensed person take work worth $1,000 or less only when no permit is required. Our license check guide shows how to confirm a license before any deposit.
What changes when the bathroom is in a rental, a duplex, a condo or a mobile home?
A lot, because San Bernardino rents. About 48.3 percent of occupied homes are renter-occupied (31,966 of 66,134), about 18.3 percent of units sit in buildings of five or more, and 6.1 percent, 4,197 units, are mobile homes, in what the Housing Element counts as 46 parks. In a multi-unit building the drain stack and walls may be shared, so the first question is who owns the pipe and who signs the permit.
Houses are rented here too. The City estimates 30 percent of its single-family homes are rentals, and an ordinance dated April 7, 2008 requires owners of rented houses, duplexes and triplexes to register and be inspected every two years for a $180 annual fee. Repairs made after an inspection notice still need a permit when they touch plumbing or electrical. The same program helps the City spot illegal rental units, and a legal second unit with its own bath goes through the San Bernardino ADU page path instead, while a wall pushed outward is covered on our San Bernardino room addition page.
Do the foothill fire rules reach a bathroom fan, a roof vent or a bath window?
Only on lots the overlays cover, and the City's text leaves a few questions open. In the foothill and very high fire zones, Municipal Code 15.10.080 bars roof-mounted turbine vents, prohibits paper-faced insulation in attics and ventilated spaces, and sets rules for vinyl window frames: welded corners, metal reinforcement in the interlock area, dual-pane glass with at least one tempered pane and AAMA lineal certification. A new exhaust duct that crosses a foothill attic, or a bath window changed during the job, touches those categories. The sections we read say nothing specific about a bath fan cap, so we ask the Building Division.
Which lots count is the harder question. The San Bernardino County Fire District adopted Ordinance 4489 on June 10, 2025 for Moderate, High and Very High zones in its Local Responsibility Areas, while Municipal Code 15.10.030 still points to a City very high zone map dated October 29, 2008. We could not tell which parcels each map covers, so the District's map viewer is where an address should be checked. Outside the foothills, Chapter 15.11 applies stricter fire-resistive standards to new tracts, new commercial buildings and blocks the Council designates after a fire. Bath windows are covered on our San Bernardino window page.
Does a 1920s or 1950s San Bernardino house need historic review for a bath remodel?
There is no historic overlay to apply. Chapter 19.18 of the Development Code, the Historic Preservation overlay, is still marked reserved for a future ordinance in the October 2019 edition, so we have no district rules to quote. What exists is Municipal Code 15.37, which requires a permit and a Planning Commission process before anyone demolishes a building 50 years old or older. It also calls for a historic resource evaluation report when the building appears on the City's 1991 reconnaissance survey, which covers structures built before December 31, 1941, or sits in a potential district that survey identified.
An interior bath remodel is not a demolition, and nothing we read treats it as one. A teardown of a small old house or the removal of a whole wing is different, so ask Planning before you design. We did not open the 1991 survey list, so we cannot say which addresses are on it.
How do high groundwater, liquefaction and a dry climate affect a new shower?
Ground conditions rarely decide a bath, but San Bernardino has some. Much of the city sits over the Bunker Hill Groundwater Basin, the 2024 Local Hazard Mitigation Plan puts downtown in the high liquefaction zone and calls almost the whole south susceptible, and Municipal Code 15.08 requires an engineer's liquefaction report for listed building types and for structural changes above 25 percent of the building area in mapped areas. The list we read names essential facilities, large assembly rooms, tall buildings and certain big occupancies, not houses, so a bath-only job should not trigger it. Ask the counter once the work reaches framing.
The sky adds little water. NOAA's 1991 to 2020 normals for Redlands, the nearest station with full data and about 9 miles away on higher ground, show 12.87 inches of rain a year and almost none in July or August, so the moisture a bath sees comes from the shower. In practice a watertight shower means a pan sloped to the drain, cement backer board and a single unbroken membrane that wraps the curb and climbs the walls. We ask for a flood test with photos before tile, which is our own practice and not a City rule.
How long does a bathroom remodel take in San Bernardino, and who does the work?
Our planning ranges are 2 to 6 weeks of design and selections, a few days of demolition and rough plumbing, 3 to 5 days of waterproofing and cure, 1 to 2 weeks of tile and fixtures and a few days for glass and the final inspection. A permit also has a clock: Municipal Code 15.04.050 treats a project with no inspection and no substantial progress shown to the Building Official in any 180-day period as abandoned and the permit as expired. Municipal Code 8.54.070 bars construction work before 7 a.m. and after 8 p.m., and 8.54.050 limits domestic power tools in residential zones to 8 a.m. through 8 p.m.
MDG Builders, CSLB #1040337, acts as the general contractor: it draws the layout, files the permit and schedules the trades, and it does not set tile with its own crew. A licensed plumber, tile setter and electrician do the field work, and each can show a license number and certificate of insurance on request. The subcontractor chain explained shows who does what, and California caps a down payment at $1,000 or 10 percent of the price, whichever is less.

What bathroom remodeling costs around San Bernardino
Our bathroom remodeling page builds its tiers around a bath of about 35 square feet: roughly $9,000 to $18,000 for a refresh, $25,000 to $40,000 for a midrange remodel that keeps the layout, $50,000 to $85,000 and up for a primary bath and $60,000 to $120,000 for a bathroom added from nothing. Those tiers rest on Los Angeles sources because we found no San Bernardino survey. Remodeling magazine's 2025 Cost vs. Value report puts a midrange bath at $27,143 and an upscale one at $85,055 there, and Thumbtack's July 2026 page for that city runs from $8,495 to $26,582. Homes here have a median value of $461,400, so finishes may land nearer the middle tiers, but only a site visit settles it. The City's fee schedule is dated 07/2020 and shows a $118.35 minimum permit fee and a $60.00 issuance fee, so permit and plan check charges appear as separate lines in a written proposal. The bathroom cost guide explains what moves a bath between tiers. Nearby cities are on the Riverside, Corona, Jurupa Valley and Los Angeles bath pages.
| What it covers | Typical range |
|---|---|
| Refresh in the same layout: new vanity, toilet, fixtures, lighting, paint, limited tile | $9,000 to $18,000 |
| Mid-range full remodel in the same layout: new shower or tub, tile, vanity, fixtures, lighting and fan | $25,000 to $40,000 |
| Upscale or primary bath: stone, custom glass, freestanding tub, double vanity, heated floor | $50,000 to $85,000 and up |
| Adding a new bathroom | $60,000 to $120,000 |

San Bernardino bathroom remodel questions, answered
Do I need a permit for a shower remodel?
Usually, because a new shower involves the valve, the drain and the framing behind the tile. Re-tiling a shower you are not otherwise changing is finish work and needs no permit in San Bernardino. Converting a tub to a shower or moving the drain is permit work. If the house predates 1978, the firm you hire also needs EPA lead-safe certification before it touches painted trim or walls.
Do I need a permit for a bathroom remodel in San Bernardino?
Yes, when the work changes plumbing, wiring, framing or ventilation. The City exempts painting, tiling, cabinets and countertops, but not the systems behind them. Plans are filed in person at the Building & Safety counter on North E Street, and the City publishes no first-review turnaround, so the first visit with us includes a permit plan.
How much does a bathroom remodel cost in California?
Our tiers assume a 35 square foot bath: about $9,000 to $18,000 for a refresh, then $25,000 to $40,000 for a midrange remodel that keeps the layout, and $50,000 to $85,000 and up for a primary bath. They rest on Los Angeles sources, not a San Bernardino survey, so a written proposal after a site visit sets your price.
Can a handyman do a bathroom remodel?
Only a very small one. California lets an unlicensed person take work worth $1,000 or less, but not when a permit is required or when that person hires help. A San Bernardino shower conversion or drain move needs a permit and a contractor with a state license and City business license, so check the license on the CSLB website first.
What is the difference between a bathroom remodel and a bathroom renovation?
A renovation usually replaces fixtures and finishes where they stand, while a remodel moves the layout, pipes or wiring, though contractors use both words loosely. San Bernardino's permit line ignores the label and follows what you touch. Tile and a vanity swap are exempt finish work, but a relocated drain or a new circuit is permit work.
How long does a bathroom remodeling take?
Allow 2 to 6 weeks for design, then about a week of demolition and rough plumbing, a few days of waterproofing and cure, 1 to 2 weeks of tile and fixtures and a few days for glass and inspection. These are our planning ranges, since the City publishes no plan-check times. Waiting on tile or shower glass causes most delays.
Do bathroom remodels in older San Bernardino homes need lead-safe work?
Yes, if a paid contractor will disturb painted surfaces in a house built before 1978. About 62.6 percent of San Bernardino homes were built before 1980, and the Census cannot separate 1978 from 1979, so check your own build year. Owners working on their own homes are generally outside the EPA rule.
Is remodeling a bathroom worth it?
Remodeling magazine's 2025 Cost vs. Value report for Los Angeles shows a midrange bath recouping about 89.6 percent of its cost at resale, against about 42.3 percent for an upscale bath. That favors the middle tiers. We found no San Bernardino resale study, so treat the figures as a regional guide, not a forecast.
