Fast, Reliable Bathroom Remodeling Across Highland
Bathroom remodeling in Highland carries requirements most Inland Empire contractors never deal with: wildfire-zone venting rules, wind-load ratings on windows, and layered city-county permit review that can stall a project for months if you miss a step. We know exactly what Highland’s building department asks for, because we pull permits here every month. Sunburst ADU Builders handles the full remodel, from first inspection to final sign-off, with written line-item pricing so you see where every dollar goes. Call (855) 676-6807 to schedule a free estimate at your home, whether you’re off Base Line, up in East Highlands, or anywhere between.
Why Sunburst ADU Builders Is Highland’s Preferred Bathroom Remodeling Company
We are a Highland-based builder, not a franchise dispatching crews from Riverside or Ontario. That matters here, because Highland’s permit process runs through both city and county channels depending on whether your parcel falls in the unincorporated pockets, and a remodeler who doesn’t know the boundary can file the wrong paperwork on day one. We know which Highland parcels need San Bernardino County fire review and which go straight through the city’s counter process.
Homeowners in Highland have hired us for bathroom remodels on 1950s ranch homes near Highland Avenue, newer east-side tracts around Greenspot Road, and foothill parcels up toward the base of the mountains where WUI codes change the scope completely. Our work holds up in the Santa Ana wind season, not just on install day. Noel Carrasco leads every project from the first walkthrough, and he’s the person who walks the final inspection with the city, too. If the inspector flags something, we fix it that week, not a month later.
Our Bathroom Remodeling Services in Highland
Bathroom Remodeling
Hall baths, primary suites, guest baths, and kids’ baths in Highland homes built from the 1950s through the 2000s all fall under our scope. We tear out tile, reconfigure layouts, replace vanities, rewire circuits, and install new plumbing fixtures, keeping the work compliant with current code, not just what passed when the house was built. Most of the older homes near downtown Highland still have cast-iron drain lines and 60-amp panels, so we often run new circuits and replace trap arms while the walls are open.
ADU Bathroom Additions
Because we build ADUs across Highland, we’re unusually good at adding a bathroom inside a detached unit, whether it’s a garage conversion off Victoria Avenue or a new prefab structure in the backyard. The plumbing, venting, and waterproofing for an ADU bath has to be right the first time, because the unit gets inspected as habitable space, not as an accessory. We handle the rough-in, fixture set, and finish work as one continuous job, so the ADU bathroom is ready when the certificate of occupancy is issued.
Fire-Resistant Bathroom Upgrades
This is the piece most Highland homeowners don’t hear about from a general remodeler. If your parcel sits within the wildfire severity zone, which covers much of the foothill belt, your bathroom exhaust fan vent, window, and even certain wall assemblies have to meet WUI standards. We install ember-resistant vent covers, fire-rated Type X drywall where the code requires it, and dual-pane tempered windows rated for both wind load and radiant heat. We document everything, because insurance underwriters in Highland ask.
General Contractor
Sometimes a bathroom remodel in Highland turns into a broader project once we open the walls, whether it’s corroded galvanized supply lines from the orchard-era subdivision days or dry rot in a bathroom that shares a wall with the exterior. Because Sunburst operates as a full-scope builder, we don’t stop at the bathroom threshold. We can reframe, re-roof, re-side with James Hardie fiber-cement, or run a new electrical panel in the same permit set, which saves Highland homeowners from coordinating two contractors on overlapping work.

How Highland’s Building Code Changes the Scope
Highland sits in the foothills belt where the Santa Ana winds, wildfire risk, and the city’s aggressively pro-ADU posture collide. A bathroom remodel here often triggers questions that never come up on a flat central-city lot. The big one: does your parcel fall in a wildfire severity zone? If it does, San Bernardino County fire review applies to any remodel that alters exterior penetrations, which includes bathroom exhaust fans, windows, and skylights. That means ember-resistant venting, which the cheap quote skips because the contractor doesn’t know the local rule. It also means your new bathroom window may need a higher wind-load rating than the one it’s replacing, especially if the elevation faces the open wind corridor running down through the Highland Hills area.
We’ve also seen what happens when permit paperwork doesn’t line up. On a 1950s ranch in the Highland Hills area, we remodeled a hall bath where the original window faced the Santa Ana wind corridor; we upgraded to a dual-pane tempered unit with ember-resistant mesh and a Class A roof assembly, then documented the WUI compliance for the homeowner’s insurance. The inspection passed first time after we added a fire-rated vent and sealed penetrations. That’s the difference between a remodeler who does Highland work every week and one who enters the zip code into a GPS.
What a compliant quote in Highland includes that a cheap one leaves out:
- Ember-resistant vent covers on every bathroom exhaust fan termination
- Fire-rated sealant at all exterior wall penetrations
- Dual-pane tempered glass on windows in wind-exposed elevations
- Type X gypsum board in fire-rated assemblies where the review requires it
- Line-item documentation for the insurance file, including product ratings and inspection sign-offs
If a contractor’s quote doesn’t list these items, ask why. If they don’t know the answer, that’s your signal to call someone who does.
Trusted Brands We Service in Highland
Our Bathroom Remodeling team installs fixtures and materials from brands that hold up under Highland’s heat, wind, and ember exposure. We work with Cover, Dvele, and Mighty Buildings on ADU bathroom modules, but for stand-alone remodels in existing Highland homes, we spec based on what survives the climate, not what has the best marketing. When you call us for a bathroom remodel in Highland, we’ll walk you through material choices and what each one costs, so you’re comparing real numbers, not brochures.
Common Bathroom Remodeling Problems We See in Highland Homes
- Failed WUI inspections from non-compliant bathroom exhaust vents. We’ve fixed multiple Highland remodels where another contractor installed a standard plastic vent cover, and the county flagged it immediately. The fix is cheap if caught early, but if the insurance claim has already been filed after a fire event, an undocumented non-compliant vent can void coverage.
- Santa Ana wind pushing water through bathroom windows on exposed foothill elevations. Highland homes facing the wind corridor need windows rated for the actual wind load, not just the standard residential rating. We test the rough opening and check the original window’s rating before ordering a replacement, so we don’t put the wrong glass in a wall that takes the full force of a Santa Ana event.
- Cast-iron drain lines in 1950s-70s ranch homes off Base Line and Victoria. The original drains in Highland’s orchard-era subdivisions are often paper-thin by now. When we open a bathroom wall, we usually find the galvanized supply lines and cast-iron hubs are rusted enough that replacing them now is cheaper than a slab leak later.
- Slopes and grading complicating ADU bathroom rough-ins. A detached ADU bathroom on a sloped Highland lot can trigger grading and drainage review if the unit sits near a downhill slope. We handle that review before we pour any concrete, because discovering it mid-project doubles the plan-check timeline.
Pricing for Bathroom Remodeling in Highland, CA
A typical hall bathroom remodel in Highland runs $14,000 to $24,000 depending on layout changes, fixture grade, and the condition of existing plumbing. Adding a bathroom to an ADU typically lands between $18,000 and $35,000, driven by the rough-in scope and whether the unit sits on a slope that needs drainage review. Primary suites in higher-end Highland homes can push $30,000 to $55,000 when you add custom tile, a curbless shower, and a heated floor. WUI compliance materials add roughly $800 to $2,500, depending on how many penetrations and windows fall in the fire zone. That’s not optional if your parcel is in the severity zone. Call (855) 676-6807 for an exact quote, no charge.

FAQs – Bathroom Remodeling in Highland
Yes, if your parcel falls within a wildfire severity zone, which covers large parts of Highland’s foothill belt. The required items typically include ember-resistant exhaust fan vents, fire-rated sealant at exterior penetrations, and Type X drywall in fire-rated assemblies. We verify your zone before quoting, so the scope is right from day one. Call (855) 676-6807 to confirm your parcel’s status and get a free estimate.
Windows on elevations facing the Santa Ana wind corridor in Highland need a higher wind-load rating than what a standard residential window carries. We check the original window’s rating and the elevation’s exposure before ordering, then spec a dual-pane tempered unit that meets the code requirement. It’s a small line item that prevents leaks and breakage when the winds hit.
A compliant quote for a Highland bathroom remodel should list the specific WUI-rated materials, including vent covers, window ratings, and any fire-rated assemblies, with product names and test standards. After the work is done, we provide a documentation packet with the inspection sign-offs and material ratings, which your insurer can use to verify compliance. That packet matters if you ever file a claim.
Yes. If the ADU bathroom is part of a detached unit on a sloped lot in Highland, the bathroom’s plumbing and foundation may trigger grading and drainage review, especially if the unit sits near a downhill slope. We file the grading review at the start of the permit process, not after the floor plan is locked in, so the plan-check timeline doesn’t double.
Highland’s permit process splits between city and San Bernardino County review depending on whether your parcel is in the city proper or an unincorporated pocket, and WUI review applies to any remodel that alters exterior penetrations. A bathroom remodel that adds an exhaust fan, window, or skylight can trigger fire review in the severity zone. We file through the correct channel from the start, because re-filing after a rejection costs weeks.
