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

Fast, Reliable Garage Conversion Contractor Across Mentone

Garage conversions in Mentone typically take 8 to 14 weeks from permit submittal to final inspection, and most projects fall between $95,000 and $185,000 depending on whether the garage is attached, detached, or needs fire-resistive upgrades under Chapter 7A. If you’re on a half-acre lot off Highway 38 or near Crafton Avenue, you’re not dealing with Redlands or Highland city rules. You’re in unincorporated San Bernardino County territory, which changes the permit path, the material list, and the price. We know that because we’ve built here. Call (254) 602-5618 and you’ll get a live person, not a voicemail, any hour of the day.

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

We are the ADU company of the Kingswell family, building garage conversions and accessory dwelling units since 2010. Russ Delmar leads our team, and every project in Mentone operates under The Kingswell Guarantee: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee on every job. If something isn’t right within 365 days, we come back and make it right. That’s in writing, not a handshake.

Mentone homeowners tell us the same thing over and over: they called a contractor, got a rough verbal number, then watched the price climb once the permit hit the County. That doesn’t happen with us. We scope the septic evaluation, fire-rated assemblies, and panel upgrades before we quote. The number we hand you is the number you pay. Our Garage Conversion Contractor team has walked enough Mentone parcels to know which questions to ask before we ever set foot on the property.

Background-checked, uniformed technicians show up during the window we give you. We don’t leave a job site looking like a demolition zone. And when you call with a question about your build or your guarantee, a live person answers. Day or night. That’s the Kingswell Way.

Garage Apartment Conversion in Mentone

Garage Apartment Conversion in Mentone means turning an existing garage, usually mid-century ranch construction on a large semi-rural lot, into a self-contained living unit with its own kitchen, bath, and entrance. Around Mentone, this is one of the most practical ways to add rental income or space for family without building new from the slab up. It’s also the conversion type most affected by County rules here, because many detached garages sit far from the main house and require longer trenching, separate utility runs, and their own fire-rated assemblies.

Detached Garage Conversions on Half-Acre Lots

Mentone’s citrus-belt history left behind a lot of detached garages set back from the house. On a half-acre parcel, that’s actually an advantage: you have room to run utilities, stage materials, and keep the build away from your daily life. The tradeoff is cost. Longer electrical runs, separate water and sewer lines, and sometimes a new service panel add $15,000 to $40,000 over an attached conversion. We price all of that upfront.

Converting Mid-Century Garages to Living Space

Many Mentone garages were built in the 1950s and 60s with slab foundations and minimal framing. Some convert cleanly. Others need structural reinforcement, new roof sheathing, or complete re-insulation before drywall goes up. A straightforward garage-to-bedroom conversion here runs $65,000 to $110,000. A full garage apartment with kitchen and bath lands between $120,000 and $185,000. We’ll give you a written line-item quote so you can see exactly where the money goes.

Garage Conversion Permit in Mentone

Garage Conversion Permit in Mentone is not a city permit. Because Mentone is an unincorporated community, your ADU or garage conversion permit goes through San Bernardino County Land Use Services. That’s a different review path than Redlands, Yucaipa, or Highland, and it catches a lot of homeowners off guard. You don’t need a city stamp. You need County approval, and often a fire district review if your parcel sits within a High Fire Hazard Severity Zone.

County Review and Fire District Overlap

Hillside-adjacent parcels in Mentone commonly trigger Chapter 7A fire-resistive construction requirements. That means exterior walls, roofing, vents, and sometimes windows have to meet a fire-rated standard that lower-valley garage conversions never see. We handle the plan set coordination with the County and the fire district so you’re not bouncing between agencies. Expect the permit phase to add 4 to 8 weeks to the timeline, and budget $4,000 to $12,000 for plans and permit fees depending on your parcel’s fire zone.

Septic System Adequacy and the County

A large share of Mentone parcels still run on private septic systems. San Bernardino County requires a septic system adequacy evaluation before it will approve an ADU that adds new dwelling-unit load. That evaluation can take weeks, and if the tank or leach field can’t handle the additional load, you’re looking at $15,000 to $40,000 in upgrades before the garage conversion can move forward. We order the evaluation early so it never blindsides you mid-project.

Trusted Brands We Service in Mentone

We work with established ADU brands and materials that hold up in Mentone’s heat and fire-season wind. For a hillside parcel, we might spec James Hardie fiber-cement siding for its Class A fire rating. For a flat valley lot, a prefab unit from Abodu or Cover can shorten the timeline meaningfully. Dvele panels work well when a homeowner wants high-performance insulation for summers above 105°F. We match the system to your lot, your budget, and your timeline, and we explain the tradeoffs in plain English before you commit to anything.

Common Garage Conversion Contractor Problems We See in Mentone Homes

• Wrong jurisdiction assumption. Homeowners file with Redlands or Highland because that’s where their mail goes, then the application bounces back. We verify County jurisdiction on day one so the plan set isn’t redone mid-project.
• Septic evaluation skipped. A homeowner budgets for framing and drywall, then the County requires a septic adequacy evaluation that adds weeks and sometimes tens of thousands in upgrades. We scope it into the schedule and the price before anything gets demoed.
• Standard materials on a hillside parcel. A contractor specs standard stucco and Class C roofing on a parcel inside a High Fire Hazard Severity Zone, then fails fire district inspection. We use Chapter 7A-compliant assemblies from the first material takeoff.
• 100-amp panels that can’t carry the load. Mid-century ranch homes around Crafton Avenue and Mentone Boulevard often have 100-amp service and galvanized supply lines. Adding a dwelling unit usually means a service upgrade first, which is a real cost that a lot of contractors only mention after the walls are open.
