Garage conversions in Beaumont typically run $85,000 to $165,000 for a full one-bedroom ADU, and most projects take 14 to 20 weeks including architectural review. If you live in Tournament Hills, Sundance, or anywhere else in Beaumont, you’ve probably wondered whether that underused two-car garage could become a rental unit or an in-law suite. It can, and we do this work every month across Beaumont. Our crews know the HOA rules, the Wildland-Urban Interface fire codes, and the rear-alley layouts that either help or complicate your plans. Call (831) 292-4191 and we’ll walk you through what your specific garage can become.
Why Lodgewick ADU Riverside Is Beaumont’s Preferred Garage Conversion Contractor Company
Lodgewick ADU Riverside is the ADU company of the Kingswell family, established in 2010. We specialize in Garage Conversion Contractor work across the Inland Empire, and Beaumont is one of the cities our crews serve regularly. Russ Delmar leads our team, and he insists on a simple rule: the homeowner gets a written price before any work starts. No price changes at the door. No “we discovered something” surprises unless it’s genuinely structural, and even then, you see the number in writing before we touch it.
What separates us from the contractors Beaumont homeowners have been burned by before is the paperwork. Every project carries 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 single project, before a single nail is driven. A live person answers our phones 24 hours a day, seven days a week, so when you call about your Beaumont garage conversion, you talk to a human who knows your file, not a voicemail loop.
Our technicians are background-checked and uniformed. When a crew shows up at your Beaumont home, you know exactly who is on your property. And every crew follows 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, and come back if it fails.
Garage Conversion ADU in Beaumont
A Garage Conversion ADU is the most common type of accessory dwelling unit we build in Beaumont, and it means taking your existing attached or detached garage and legally converting it into a self-contained living unit with its own entrance, kitchen, bathroom, and sleeping area. In Beaumont, this work usually falls between $90,000 and $140,000 depending on whether we’re working with an attached garage with existing plumbing access or a detached garage that needs a full sewer line run. For homeowners in Tract neighborhoods like Tournament Hills and Sundance, a Garage Conversion ADU often makes more financial sense than a ground-up build because the shell and foundation already exist.
Attached Garage Conversion for Rental Income
When your garage shares a wall with the main house, the conversion cost trends lower because you can tap existing electrical panels and water lines more directly. In Beaumont, many homeowners in the newer tract developments convert an attached two-car garage into a 500 to 550 square foot one-bedroom ADU. The HOA in Tournament Hills and Sundance typically approves this configuration when the new entrance faces the rear alley rather than the street, which is something we plan for from day one.
Detached Garage ADU with Separate Driveway
Beaumont’s older lots near downtown, and even some newer ones, had detached garages facing rear alleys. Those alleys are gold for ADU work. A detached garage conversion can get its own rear driveway, its own street number, and its own fenced yard without tripping HOA rules that prohibit front-yard accessory structures. We converted a detached garage in Sundance into a 540 square foot one-bedroom unit, reused the rear alley access for a private entrance, and added a small covered patio that the HOA signed off on because it was invisible from the street.
Garage Apartment Conversion in Beaumont
A Garage Apartment Conversion in Beaumont is essentially the same structural work as a Garage Conversion ADU, but the end use is different. These are often built for aging parents or returning adult children rather than renters. That changes the design conversation: wider doorways, zero-threshold showers, lower countertops, and sometimes a connecting door to the main house. In Beaumont, a Garage Apartment Conversion typically runs $85,000 to $135,000 depending on whether you need plumbing brought up through the slab and how much fire-rated separation the city requires between the apartment and the primary dwelling.
Garage to Living Space for Multigenerational Use
Beaumont’s rapid post-2000 housing boom created thousands of tract homes with large lots, and many of those original buyers are now three generations deep in the same house. A Garage to Living Space conversion gives grandma or the adult kids their own kitchen and bath without forcing a move. The existing structure may look simple, but we always check the foundation thickness first. Some original garage slabs in Beaumont measure thinner than current seismic code, which means a partial re-pour before framing starts. That is the kind of thing that stalls a cheap bid mid-project, and it is exactly the kind of thing we flag in writing before you sign.
Fire Code and WUI Compliance for Garage Apartments
Beaumont sits close enough to the foothills and canyons that the city enforces Wildland-Urban Interface codes, often called WUI codes, on accessory structures. For a garage apartment that means ignition-resistant vents, tempered glass on certain exposures, and exterior materials that meet fire-resistive standards. We build with James Hardie fiber-cement lap siding on most Beaumont garage apartments because it passes WUI review, holds paint color well, and comes in the neutral beige and tan palette that Tournament Hills and Sundance HOA boards approve. When we converted that Sundance garage, our crew had to reframe the original low roof section to bring it up to fire code, then color-match the siding to the HOA’s approved palette after architectural review gave the okay.
Trusted Brands We Service in Beaumont
We work with established ADU brands and material suppliers that fit Beaumont’s specific code and climate demands. Cover and Dvele both produce panelized ADU systems that handle the cooling loads Beaumont’s hot, dry summers demand, and we’ve specified them on detached garage conversions where the original shell was too compromised to reuse. Mighty Buildings panels have worked well on rear-alley lots where access is tight and we need to stage material efficiently. For siding, James Hardie fiber cement is our default in the Wildland-Urban Interface zones around Beaumont because it passes fire review and holds up to Santa Ana wind season. When you call, we’ll match the right system to your lot, your HOA, and your budget.
Common Garage Conversion Contractor Problems We See in Beaumont Homes
Beaumont’s specific mix of HOA rules, fire codes, and newer tract housing stock creates predictable failure points. These are the ones we see most often, and the ones we plan around before your first deposit:
- HOA architectural review sent back for color or roof material. Tournament Hills and Sundance both maintain approved palettes. Submitting plans without checking the palette for your specific tract adds three to six weeks to the calendar. We file the submittal packet ourselves, and we get the color selection pre-approved before plans go to the city.
- Wildland-Urban Interface requirements catching people off guard. Ignition-resistant vents, tempered glass, and specific exterior sheathing are mandatory in much of Beaumont. These items add real cost and real construction time. We list them in your written price up front, not as a mid-job surprise.
- Original garage foundations thinner than current seismic code. We see this on garages built in the 1990s and early 2000s across Beaumont’s boom-era tracts. A slab that passed code in 1998 may not pass in 2026. We check this before we quote, so you know if a partial re-pour is coming.
- Rear alley access ignored during design. Many Beaumont properties, especially in Tournament Hills and Sundance, have rear alleys originally platted for garage access. Ignoring that alley means a front-facing entrance that the HOA rejects. We design around the alley from the first sketch.
Pricing for Garage Conversion Contractor in Beaumont, CA
A typical attached garage conversion in Beaumont runs $85,000 to $140,000. A detached garage conversion with a new rear entrance and separate utility runs runs $110,000 to $165,000. A smaller garage-to-bedroom or garage-to-living-space job, without a full kitchen, can come in at $70,000 to $95,000. What moves the number most is foundation thickness, plumbing distance to the sewer line, WUI-rated materials, and whether your HOA requires specific siding or roofing materials. We give you a written line-item price before any work starts, and if something on the estimate changes during construction, you see the revised number in writing and approve it first. Call (831) 292-4191 for your free estimate.

FAQs About Garage Conversion Contractor in Beaumont
Yes, and this is the step that stalls most Beaumont garage conversions. Tournament Hills has architectural review requirements that control exterior colors, rooflines, and where an ADU entrance can face. The palette is specific: neutral beiges, tans, and certain earth tones. We prepare the submittal packet for you, including the color samples and materials list, and we file it before the city sees your plans. Expect two to six weeks for HOA review depending on when the committee meets. Call (831) 292-4191 and we’ll walk you through exactly what your tract requires.
WUI codes require ignition-resistant vents, tempered glass on certain windows, and exterior siding that meets fire-resistive standards. In practice, that means we spec James Hardie fiber-cement siding on most Beaumont garage conversions, and we budget for ember-resistant venting on the soffit and gable areas. These items add roughly $8,000 to $15,000 to a typical conversion compared to a non-WUI area. It’s not optional. We’ve seen homeowners try to skip it and get red-tagged at framing inspection.
Yes, and in Sundance that rear alley is often the difference between approval and rejection. The HOA rules in Sundance prohibit front-yard accessory structures, but a rear-facing entrance off the existing alley is typically approved because it’s invisible from the street and doesn’t change the front elevation. We used exactly this approach on a Sundance attached garage conversion, adding a private rear entrance and a small covered patio that the architectural committee approved without revisions. If your lot has rear alley access, we’ll design around it from day one.
The most common stall is submitting plans without HOA architectural review, then getting sent back when the color or roof material doesn’t match the tract’s approved palette. That resubmittal alone can burn six to eight weeks. The second most common stall is a foundation that is thinner than current seismic code, which forces a full re-pour mid-construction. When a slab that passed code in 1998 fails inspection in 2026, the project stops until the new concrete cures. We check the foundation before quoting, and we file the HOA packet before the city review, so neither of these stalls applies to our clients.
Architectural review adds two to six weeks to a garage conversion in Beaumont, depending on the HOA’s meeting schedule and whether the first submittal includes everything the committee wants to see. The fastest reviews we see are in tracts where the submittal packet includes a pre-approved color sample, the roofline matches the tract standard, and the new entrance faces the rear alley. We schedule the build around that approval window so your project does not sit half-finished waiting on a committee. Call (831) 292-4191 for a timeline for your specific street.
