A garage conversion in Redlands typically costs $85,000 to $160,000 for a full ADU with kitchen and bath, and takes four to seven months from permit submittal to final inspection. Detached garage conversions on the city’s older citrus-era lots usually run toward the higher end because of foundation and historic-review work that homeowners don’t see coming. If you’re off West Palm Avenue, in South Redlands, or up near the University Grove area, we know what plan check will flag before you spend a dollar on framing. Call (361) 315-4177 and we’ll walk the garage with you and put a written price in your hands.
We’re Garage Conversion Contractor specialists serving every corner of Redlands, and we’ve converted enough detached, alley-loaded garages here to know exactly where the surprises hide.
Why Fielding ADU Builders Is Redlands’s Preferred Garage Conversion Contractor Company

Redlands homeowners come to us after another contractor has already burned them. They’ve had a bid that doubled at framing, a permit board that stayed empty for months, or a crew that stopped answering the phone. We run a different operation inside the Garrison Partners family. The price goes in writing before any work starts. The crew shows up background-checked and in uniform. And the work is backed by The Garrison Standard: a 365-day written guarantee. If something fails inside that year, we return and make it right at no charge.
Reed Calloway leads our team, and he runs every Redlands project the way The Garrison Code lays it out: show up in the window, price in writing, build by the book, leave it clean, stand behind it for a year. No exceptions. That’s why homeowners from the historic districts down to the Canyon Road corridor call us first when they start researching a garage conversion.
Dispatch and scheduling for Redlands are coordinated from our Inland Empire office in the Riverside-San Bernardino metro, which means our crews are minutes from your job site, not an hour away. You aren’t waiting on a crew from Los Angeles or San Diego. When plan check needs a revision or an inspection gets scheduled, we can be there.
Garage Conversion ADU in Redlands
A Garage Conversion ADU in Redlands turns an existing attached or detached garage into a fully permitted accessory dwelling unit with its own kitchen, bath, entrance, and address. This is the route most Redlands homeowners take when they want rental income or a long-term place for family, because the shell already exists and the savings versus new construction are real. A Garage Conversion ADU here runs $110,000 to $160,000 depending on foundation condition, historic overlay requirements, and whether the garage is attached or detached. The price includes architectural drawings, structural engineering, permit fees, construction, and final inspection.
Attached Garage Conversion
An attached garage shares at least one wall with the main house, which usually means fewer surprises with utilities and footings. But the shared wall becomes a fire-rated assembly under current code, and that’s not optional. We frame it, insulate it, and drywall it to the standard the Redlands building department requires before we touch finish work.
Detached Garage Conversion
Detached garages on Redlands’ older lots are where we find the real cost drivers. Slabs from the 1930s through the 1950s were often poured without continuous footings, and they crack or settle. Plan check will flag it. We add stem-wall pads or full under-slab footings where the engineer directs, then build up from a foundation that will actually hold.
Garage Apartment Conversion in Redlands

A Garage Apartment Conversion in Redlands is the lighter version of a full ADU: a studio or one-bedroom living space inside the existing garage envelope with a kitchenette and bath, often without a separate mailing address. Homeowners choose this when they want a private guest suite or home office, not a rental unit. Budget $85,000 to $120,000 for a well-finished Garage Apartment Conversion in Redlands, with the final number driven by whether the existing slab passes inspection and how much of the original garage door opening must be rebuilt.
Garage to Bedroom
Converting a Redlands garage to a dedicated bedroom means meeting egress and light requirements that older garages were never designed for. You need a proper egress window or door, not just a stud wall where the garage door used to be. We handle the window design, the fire-rated wall at the old door opening, and the HVAC tie-in so the room is actually comfortable in a Redlands summer.
Garage to Living Space
This is the broadest scope: a bonus room, media room, playroom, or workshop-grade space that isn’t a bedroom and doesn’t need its own kitchen. It costs less, usually $65,000 to $95,000 in Redlands, because you’re not adding plumbing or a second egress path. The garage door still has to go, and the replacement wall still has to meet insulation and fire code.
Trusted Brands We Service in Redlands
We work with the prefab and modular platforms Redlands homeowners are already researching, including Abodu, Cover, Dvele, and Mighty Buildings. If your garage conversion pairs with a modular ADU or a conventional build, we have the drawings and the install experience to make it work. On conventional jobs we use James Hardie siding and Tuff Shed-style structures where they fit the lot and the budget. We keep the common hardware and assemblies for these systems in stock so a Redlands job doesn’t stall waiting on a shipment from out of state.
Common Garage Conversion Contractor Problems We See in Redlands Homes
- Failing slabs and missing footings. Redlands’ pre-1940s detached garages were often built directly on grade with no stem wall. Once we open the slab, we frequently find shifting or cracking that plan check won’t pass. The fix is a poured footing or stem-wall pad, and it adds real cost and a week or two to the calendar.
- Historic overlay surprises. A garage on a citrus-era bungalow in the older core of Redlands can trigger historic-preservation review before the building department will release permits. Owners who skip that check end up stalled mid-framing. We confirm the overlay status before we draw anything.
- Garage door opening shortcuts. Filling the garage door with a stud wall isn’t enough in Redlands. Current code requires an insulated, fire-rated assembly at that opening, and the driveway approach has to satisfy parking and drainage rules. Cheap bids skip this and get red-tagged at inspection.
- Utility distance problems. Detached garages at the back of deep Redlands lots can be 40 or 50 feet from the nearest sewer and power connection. Trenching that distance through mature landscaping and old tree roots adds cost beyond what a quick square-footage estimate shows.

FAQs About Garage Conversion Contractor in Redlands
A detached garage conversion in Redlands requires a full ADU permit when the finished space includes a kitchen, bath, and sleeping area with its own entrance. A simpler living space without a kitchen can often proceed under a standard residential building permit, but the city determines the classification during plan check, not before. Call (361) 315-4177 and we’ll confirm which path applies to your garage.
A full Garage Conversion ADU in Redlands takes four to seven months, measured from permit submittal to final inspection. The spread comes down to how quickly plan check processes revisions, whether historic review applies, and whether the existing slab and footings need foundation work before framing can start. We give you a written calendar with the written price.
Yes, and it can add several weeks to the front of the project. Garages on citrus-era bungalows inside Redlands’ older historic overlays may need preservation review before building permits are issued, and the review can restrict exterior changes like door placement, window style, and roofline. We confirm the overlay status before any drawings are submitted so you aren’t waiting on a revision you didn’t know you’d need.
Sometimes, but not always. Older Redlands slabs were often poured without continuous footings, and if plan check flags settlement or cracking, the slab has to be cut and a stem wall or full footing poured underneath. We assess the slab during the estimate so the written price accounts for the most likely outcome, not the best case.
The three things that move the price after demolition are foundation work hidden under the slab, historic-design-review conditions that change the exterior, and utility trenching distances from the main house to a detached garage at the back of the lot. Our written price accounts for what we can see and measure before we open walls. When something hidden emerges, we stop, show you the condition, and agree on a change order in writing before any additional work proceeds.
