ADU Company in Crestline, CA
Kitchen remodeling in Crestline usually means opening up a cramped mountain cabin kitchen that still has its original 1970s layout, and doing it on a sloped lot where every material delivery has to climb a winding road. We’re Sunburst ADU Builders, and we’ve served Crestline since 2018, handling full ADU construction plus the kitchen and bath work that turns a new unit into a rentable home. If you’re planning an ADU here or just need your existing kitchen rebuilt for modern use, call (855) 676-6807 for a free estimate. The mountain conditions change how every job is priced and planned, and we’ll walk you through that before you commit.
Why Crestline Homes Are Different
Crestline sits inside the San Bernardino National Forest, and most of its housing stock is older mountain cabins and mid-century vacation homes built on steep, irregular lots. Many of these properties still run on septic systems with limited utility capacity, so an ADU or a kitchen remodel often starts by working around an existing small footprint rather than assuming a flat, fully serviced suburban lot. That changes everything from where we place a new structure to how we route plumbing and electrical.
The bigger factor is fire. Crestline is inside a Cal Fire Very High Fire Hazard Severity Zone, which means most ADU projects here trigger defensible-space and emergency-access review through San Bernardino County. Snow load matters too. Roofs need to handle real freeze-thaw cycles, and ice-dam protection is not optional. These constraints don’t exist for a flat-lot project in San Bernardino or Riverside, and a builder who has only done lowland work will stumble on them. We plan for fire-hardening, snow-rated roofs, and mountain access from the first site visit, because that’s what a Crestline job actually involves.
Our Main Crestline Services
Two services drive most of the calls we get from Crestline homeowners: full ADU construction and bathroom remodeling for older cabins and new units alike. Here’s what each one looks like on a mountain lot.
ADU Builders in Crestline
Adding an ADU in Crestline means navigating San Bernardino County’s mountain ADU ordinance, which can allow a legal nonconforming cabin lot to add a unit that would never get approved in a flat suburban zone. The catch is that nearly every project also triggers fire-safety review, defensible-space planning, and often septic or utility upgrades. We work across prefab, modular, and custom builds so the unit you choose actually fits your sloped lot instead of forcing a one-size-fits-all plan onto terrain that won’t cooperate. ADU Builders in Crestline covers the full process.
Bathroom Remodeling in Crestline
Most older Crestline cabins have bathrooms that were built when a 5-foot tub and a single vanity were considered plenty. Water pressure from aging mountain plumbing and moisture from cold winters make these rooms wear out faster than lowland bathrooms. We rebuild them with ventilation and waterproofing rated for a freeze-thaw climate, and we can tie the work into a larger ADU project or handle the bathroom on its own. Bathroom Remodeling in Crestline explains what that process looks like.

Kitchen Remodeling in Crestline
Kitchen remodeling in Crestline is usually about fixing a room that was never designed for how people cook now. The original cabin kitchens in this area are small, often dark, and built around whatever the septic and electrical systems could handle forty or fifty years ago. Add in mountain winters where a poorly insulated wall sweats and freeze-thaw cycles stress every pipe, and you get kitchens that need real rebuilding rather than cosmetic updates. We handle the full Kitchen Remodeling scope: layout changes, new cabinetry, counters, flooring, lighting, and the plumbing and electrical work that makes it all function. Because we also build ADUs, we can coordinate your kitchen work with an attached or detached unit so both projects share one permit timeline and one contractor instead of two competing schedules.
Full Kitchen Remodel
Signs you need it
The layout hasn’t changed in decades, cabinet doors sag, counter space is so tight you prep food on the stovetop, and the room can’t handle a modern refrigerator or range without a rewiring job.
What it costs in Crestline
A full kitchen remodel in Crestline typically runs $45,000 to $90,000 depending on cabinet grade, countertop material, appliance level, and whether we’re moving plumbing or load-bearing walls.
How we do it
We start with a site visit to check the existing electric panel, plumbing runs, and floor structure, then design a layout around your lot’s constraints, pull county permits, and build in phases so the kitchen is down for as little time as possible.
Kitchen Update
Signs you need it
The cabinets and structure are basically fine but the surfaces, lighting, sink, and appliances are dated or worn, and you want a refresh without changing the footprint.
What it costs in Crestline
A mid-range kitchen update in Crestline typically runs $20,000 to $45,000, covering new doors or refacing, counters, a sink and faucet, lighting, and basic electrical upgrades.
How we do it
We swap finishes and fixtures, upgrade the lighting and outlets to current code, and replace worn surfaces first, keeping the existing cabinet boxes and layout when they still work.

Mountain access and fire-safety requirements can push materials and labor higher than a comparable flat-lot job in the valley, which is why we give written line-item quotes before work starts. Estimates are free, and the price we quote is the price you pay unless you change the scope in writing.
How long does a kitchen remodel take in Crestline?
A full kitchen remodel in Crestline usually takes 6 to 10 weeks from demo to final inspection. Weather delays on deliveries up the mountain and county inspection scheduling account for most of the variance. Call (855) 676-6807 to get a timeline for your specific project.
Can I remodel a kitchen while adding an ADU in Crestline?
Yes, and doing both under one contract often saves money because we share mobilization, dump fees, and permitting overhead. We coordinate the two scopes so your primary kitchen and the new unit’s kitchen finish around the same time.

We build and finish ADUs from Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed conversions, and we stock common trim, panel, and hardware parts locally so small fixes don’t wait on a factory shipment.

What Crestline Customers Say
"Every invoice was tied to a completed milestone, so I always knew what I was paying for."
— Henry Kim"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Hector Torres"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."
— Jodi Reed
