Fast, Reliable Garage Conversion Contractor Across Bloomington
Turning an existing garage into living space in Bloomington usually costs between $85,000 and $150,000 depending on the size of the garage and what the county inspection turns up once walls are open. We’ve worked on conversions across Bloomington for years, which matters here more than most places. Why? Bloomington is unincorporated San Bernardino County, so every permit runs through County Land Use Services rather than a city hall. That single fact changes how your conversion gets approved, how long it takes, and which surprises are most likely to surface. Call (254) 602-5618 and we’ll walk you through exactly what your garage needs before we ever pick up a hammer.
Why Lodgewick ADU Builders Is Bloomington’s Preferred Garage Conversion Contractor Company
Bloomington homeowners who have been through a bad remodel before tend to ask the same questions: will the price actually hold, will someone show up when they said they would, and will anyone come back if the work fails six months later. Those are exactly the questions our Garage Conversion Contractor team is built around. Every project starts with a written price before any work begins. Every project ends with the 365-Day Done Right Promise in writing; if something isn’t right within a year, we return and fix it at no charge. That’s The Kingswell Way, and it isn’t a marketing line. It’s the actual contract.
We run background-checked, uniformed crews on every Bloomington job. When someone knocks on your door to start the framing or electrical work, you know who they are and why they’re there. We answer the phone with a live person 24 hours a day, because nobody wants to leave a voicemail about a county inspection that just failed and hope someone calls back eventually. The team is led by Russ Delmar, and every Bloomington conversion gets his direct attention on the permit path, the pricing, and what happens when the walls come open.
Garage Conversion ADU in Bloomington
Garage Conversion ADU work in Bloomington means converting an attached or detached garage into a legal accessory dwelling unit, a self-contained living space with its own kitchen, bath, and entrance. The process is different here, because Bloomington has no city building department. Your ADU permit is issued by San Bernardino County Land Use Services, and on the large legacy parcels common in this area, a zoning conformance check on RL or AG zoning may need to clear before the permit can even be pulled. A standard garage-conversion quote in Bloomington runs from $85,000 for a small attached garage up to $150,000 for a detached two-car structure with a full kitchen and bath.
The county path from permit to pass
The county sequence matters because it shapes the entire budget. We check the parcel zoning first, then submit plans to Land Use Services, then pull the permit. On oversized lots that still carry Rural Living or Agricultural zoning, that first check can add two to three weeks that a neighboring Rialto or Fontana project would skip entirely. We price that timeline into the schedule up front, so nobody is surprised when the county takes its time.
What the conversion actually includes
A typical Bloomington garage ADU involves new subfloor and flooring, drywall or paneling, electrical, plumbing for a kitchenette and bath, insulation sized for inland valley heat, and a mini-split HVAC system. Older garages built in the 1950s and 1960s often need a service panel upgrade from 60 or 100 amps to 200 amps before the county will sign off. We put that line item in the written estimate, not as a surprise change order after demo.
Garage Apartment Conversion in Bloomington
Garage Apartment Conversion in Bloomington takes a detached garage, often a leftover from the area’s agricultural past, and creates a full rental or in-law apartment above or alongside the original footprint. It’s one of the most common projects on Bloomington’s oversized lots, where the home may sit on 15,000 to 20,000 square feet and the garage has been used for storage or as a workshop for decades. A garage apartment conversion in this market typically lands between $110,000 and $160,000, with the higher end reflecting full second-story additions or extensive structural work on older outbuildings.
Large lots, large possibilities
What makes Bloomington different from Rialto or Fontana is land. Many parcels here are large enough that lot-size restrictions never even enter the conversation. A detached garage conversion has room to expand, add a separate entrance, and still leave plenty of yard space between the main house and the new unit. That’s a real advantage for homeowners who want rental income or a private space for aging parents.
Ag-era garages need a structural eye
Garages built during Bloomington’s semi-rural era weren’t always built to living-space standards. We regularly find undersized framing, slabs with no vapor barrier, and electrical service that was fine for a workbench and a few lights but nowhere near enough for a stove, HVAC, and a bathroom. The county inspection will catch these issues. We prefer to catch them first and price them in writing before the first wall comes down.
Trusted Brands We Service in Bloomington
We work hands-on with leading ADU systems like Abodu, Cover, Mighty Buildings, and Dvele, matching the right approach to each Bloomington lot, budget, and timeline. Some homeowners want a prefab path that gets a permit-ready design fast; others need a fully custom conversion of an existing garage that can’t fit a factory-built module. We walk both routes honestly, and we don’t push a system just because it’s easier for us. Hardie siding and similar James Hardie materials also come up often on Bloomington conversions where the exterior needs to handle years of inland sun and heat. Call (254) 602-5618 and we’ll tell you what fits your garage.
Common Garage Conversion Contractor Problems We See in Bloomington Homes
- Cloth-wrapped wiring and undersized panels. Houses from the 1950s and 1960s around Bloomington frequently still have 60 to 100 amp service with original cloth-insulated wiring, and the county won’t energize a new ADU on that. Upgrading to 200 amps with a new panel is a standard part of our proposals, priced clearly up front.
- Rotted bottom plates behind old workbenches. Water seeps in at the slab edge over decades, and nobody sees it until the workbench comes out. We’re used to finding soft framing along the bottom of older Bloomington garage walls, and we sister or replace it before any drywall goes in.
- Slabs with no waterproofing. Garage slabs were poured to park a car on, not to live on. Without a vapor barrier and membrane, moisture wicks up and ruins flooring within a year. We install the barrier and membrane before finish work begins, which is another truth-in-pricing conversation we have with every homeowner up front.
- Zoning conformance issues on legacy parcels. If your Bloomington lot still carries RL or AG zoning, you can’t just start building. The parcel has to clear a county zoning conformance check first. We’ve seen conversions stall for months because nobody ran that check before demo started. We run it first, every time.

FAQs About Garage Conversion Contractor in Bloomington
San Bernardino County Land Use Services issues every ADU permit in Bloomington, because the community is unincorporated and has no city building department. On parcels with legacy RL or AG zoning, a zoning conformance check must clear before the permit is pulled. Call (254) 602-5618 and we’ll verify your parcel’s zoning before anything else happens.
The honest answer is that most Bloomington contractors quote the garage they can see, not the walls they haven’t opened yet. Then the county inspection flags the 60 amp panel, the rotted bottom plate, or the missing vapor barrier, and the price jumps. We solved that problem by writing allowances into the contract for the known issues common to 1950s and 1960s garages here, and any surprise gets priced and signed off in writing before we touch it.
Almost never, if it’s a typical Bloomington ag-era garage with 60 to 100 amp service. The county requires a modern panel sized for the ADU’s load, which means 200 amps in most cases. We include the upgrade in the written estimate so it doesn’t show up as a change order later.
We size the mini-split for peak inland valley heat and over-insulate the attic and walls beyond the minimum the county requires. A garage that stays comfortable in July is a garage you’ll actually use year-round. The HVAC line item in our Bloomington proposals reflects real summer conditions, not a coastal spec sheet.
We inspect first, write allowances for what Bloomington garages typically hide, and any genuinely unexpected condition gets a written addendum with a firm price before we proceed. The county inspector sees the same conditions we do, and our job is to make sure none of it blindsides you after the drywall is ordered. That’s the Kingswell Way, and it’s in every contract.
