Garage Conversion Contractor in Highland - Design, Permits and Build Under One Contract

Fast, Reliable Garage Conversion Contractor Across Highland

A garage conversion in Highland typically costs between $85,000 and $145,000 for a full permitted ADU, and most projects take 10 to 16 weeks from permit submission to final inspection. That’s the honest range we give homeowners before we ever set foot on the property. If you live north of Base Line or up toward Panorama, your number may sit higher because of fire-zone construction requirements most contractors don’t catch until after you’ve already signed. We do. Call (254) 602-5618 and we’ll walk your parcel through the CAL FIRE map before we quote a single dollar.

Why Lodgewick ADU Builders Is Highland’s Preferred Garage Conversion Contractor Company

Homeowners in Highland call us after they’ve been through the wringer with someone else. The story is usually the same: a bid that looked clean, then a change order that landed mid-demo when the walls came open and the 100-amp panel couldn’t carry the load. Our crews work differently. Russ Delmar runs our Highland projects, and he insists every job starts with an inspection of what’s actually inside the walls, not what’s visible from the driveway. That’s the Kingswell Way: say the price before the work, show up in the window given, leave the place cleaner than found, put the guarantee in writing, come back if it fails.

We’re part of the Kingswell family of home-service companies, founded in 2010. Every project operates under the 365-Day Done Right Promise. If the work isn’t right, we come back and make it right. That commitment is in writing on every job, not just spoken. And when you call, a live person answers. Not a voicemail tree. Not a chatbot. A person who knows Highland and can pull up your file.

Our dispatch and scheduling are coordinated from the brand’s Inland Empire office, but the crews working on your garage live and work right here in the San Bernardino foothill communities. That local presence matters when a Santa Ana wind event hits mid-project, or when a permit office flags something that needs a same-week response. We’re not routing crews from two counties away.

Garage Conversion ADU in Highland

A Garage Conversion ADU in Highland is the fastest path to a permitted, rentable living unit on your existing lot, and it’s the work our Garage Conversion Contractor team does most often on the 1960s-to-1980s ranch homes that fill Highland’s residential core. You already own the structure. The slab is there, the walls are there, the roof is there. The job is turning that shell into a legal dwelling: insulation, drywall, electrical, plumbing, a kitchenette, a bathroom, a separate entrance. In Highland, a conversion ADU can run $85,000 to $125,000 for a standard single-car garage, depending on what the existing systems can support.

What the conversion actually involves

Most Highland homeowners think a garage conversion is mostly cosmetic. It isn’t. The real work happens behind the drywall: running new circuits, adding a subpanel or upgrading the main panel, trenching for sewer and water, and often replacing the slab edge where decades of irrigation runoff have rotted the sill plate. A garage built in 1972 off Panorama Drive had all of that waiting behind the stucco. We scoped it, priced it, and got it approved in writing before demo continued.

When the fire zone changes everything

If your parcel sits in a Very High Fire Hazard Severity Zone, which is common on streets climbing toward the foothills north of Base Line, the permit office will require Chapter 7A ignition-resistant construction: ember-resistant vents, Class A roofing, fire-rated siding. That single designation can add $15,000 to $25,000 to a detached garage conversion budget. We pull the CAL FIRE FHSZ map lookup before we draw plans, so you know your real number on day one, not at permit intake.

Garage Apartment Conversion in Highland

A Garage Apartment Conversion in Highland is what many homeowners actually mean when they say “garage ADU”: a self-contained living space with its own kitchen, bath, and entrance, built for a parent, an adult child, or a tenant. In Highland’s ranch-home neighborhoods, where lots often run 6,000 to 10,000-plus square feet, these conversions make particular sense. The structure is already set back from the main house, which gives you natural privacy and a separate address. Expect $95,000 to $145,000 for a full apartment conversion with a kitchen and a dedicated bathroom, depending on plumbing runs and panel capacity.

Plumbing and panel reality

Those 1960s and 1970s Highland homes were built with galvanized supply lines and 100-amp panels, and both of those become the decisive numbers in a garage apartment conversion. Gray water from a new bathroom requires its own branch line and vent, and a loaded 100-amp panel won’t carry an electric range, a mini-split, and a water heater along with the main house. We write panel upgrades and partial re-pipes into the contract as line items, priced before demo starts.

Getting the utilities right the first time

Highland’s foothill microclimate throws one more variable at garage apartment projects: hard freezes. Exposed water lines and rooftop mini-split condensers see wider temperature swings up toward Panorama and the upper tract developments than the valley floor gets. That’s why we insulate and route supply lines inside conditioned envelope walls wherever possible, and why we specify cold-climate mini-splits when the unit sits above about 1,300 feet of elevation.

Trusted Brands We Service in Highland

We work daily with the ADU and panelized-building brands Highland homeowners ask about most, including Abodu, Cover, Dvele, and James Hardie. If you’ve already researched a prefab or panelized garage apartment and want someone local to handle the site work, the foundation, the utilities, and the finish, we’re your crew. For fire-zone parcels, we recommend James Hardie ignition-resistant siding and ember-resistant vent assemblies that meet Chapter 7A without looking industrial. We keep common brand-specific components and trim in stock for Highland jobs, which saves you a week or more on lead times. You get one point of contact for the brand work and the site work, and one written guarantee covering both.

Common Garage Conversion Contractor Problems We See in Highland Homes

• The 100-amp panel that’s already maxed out. Nearly every 1960s-to-1980s Highland ranch we open has a loaded panel with no room for the circuits a conversion ADU needs. We verify capacity during our first inspection and price the panel upgrade as a written line item before any contract is signed.
• The fire hazard zone that surfaces at permit intake. Parcels north of Base Line can be mapped VHFHSZ only when the permit office runs the address. That triggers Chapter 7A materials and a $15,000 to $25,000 add. We look up the CAL FIRE designation before we draw.
• Cloth-wrapped or aluminum branch wiring. Highland homes built before about 1975 often carry wiring that won’t pass a modern load calculation for an ADU. We scope partial rewiring during the inspection phase and put it in the written quote, not a mid-job surprise.
• Sill plate rot from irrigation runoff. Decades of sprinklers aimed at the garage’s stucco edge create rot at the sill plate and floor edge, and Highland’s freeze-thaw swings make it worse. We check the slab-to-stucco junction on every job and price any sill replacement before you sign.
