Fast, Reliable ADU Builders Across Home Gardens
If you’re searching for ADU Builders who understand how Home Gardens works, you’ve found the right crew. We’re Lodgewick ADU Builders, the ADU company of the Kingswell family, and we’ve been building accessory dwelling units, garage conversions, and home additions in Home Gardens since our founding in 2010. The big thing to know about Home Gardens: this is unincorporated Riverside County territory. No city hall. No municipal permit counter. Every ADU permit routes through Riverside County Building & Safety, and that one fact trips up more homeowners and out-of-area contractors than anything else. Call (254) 602-5618 and you’ll get a live person, not a voicemail loop, 24 hours a day.
Why Lodgewick ADU Builders Is Home Gardens’s Preferred ADU Builders Company
Home Gardens homeowners call us because we already know the county pathway. We don’t send you to the City of Corona’s permit counter just to get turned away and redirected to Riverside. We open the county’s FAST online portal and route through the unincorporated-area ADU pre-app checklist from the first submittal. No wasted weeks. No surprises at plan review.
Every Home Gardens project runs under The Kingswell Guarantee. That means a written price before any work starts, a defined arrival window, a clean job site, and a written guarantee delivered on the project before we drive the first nail. If the work isn’t right within 365 days, we come back and make it right. Free. That’s the 365-Day Done Right Promise, and it’s in writing on every Home Gardens job.
Our crews are background-checked and uniformed, so you always know who’s on your property. Russ Delmar leads our ADU team, and he’s walked dozens of Home Gardens lots with their 1950s detached garages, 100-amp panels, and undersized main service. When Russ says the electrical upgrade has to happen before the ADU can be energized, he’s not guessing. He’s seen it a hundred times.
ADU Contractor in Home Gardens
An ADU Contractor in Home Gardens does a lot more than frame walls and hang drywall. The contractor is the person who pulls the Riverside County permit, schedules the county inspections, coordinates the electrical service upgrade, and makes sure the county’s unincorporated-area ADU checklist gets satisfied at every step. In Home Gardens, the contractor also has to plan for summer heat that regularly tops 100°F, which means a dedicated mini-split cooling scope is not a luxury add-on. It’s required for the unit to pass plan review and remain rentable in July and August.
Electrical and Permit Coordination
Most post-WWII Home Gardens homes carry 100-amp electrical panels. An ADU with a mini-split, an induction range, and lighting won’t fit on that service. We coordinate the main panel upgrade with the ADU build so the county inspector approves both at once. One submittal, one inspection sequence, one written price.
Garage Conversion Labor
A detached one-car garage from 1958 is the most common conversion target in Home Gardens. The framing, the slab, the original door openings, and the electrical all get scrutinized at county plan review. We handle that entire scope as the general contractor, so you’re not chasing three separate trades.
ADU Design in Home Gardens
ADU Design in Home Gardens starts with two things the standard plan sets don’t address: the county’s unincorporated-area setback and lot-coverage rules, and the valley heat that makes thermal performance a make-or-break issue. A stock ADU plan drawn for a coastal city or an incorporated Riverside suburb will stall at Riverside County plan review. We design from the county’s ADU ordinance language from the first sketch, so the plan set matches the checklist instead of fighting it.
Thermal and HVAC Design
Summer highs above 100°F with limited coastal breeze relief mean the ADU needs its own cooling system. We specify dedicated ducted mini-splits sized per square foot and orientation, because a unit that leans on the main house’s HVAC becomes unrentable in July. Thermal design in Home Gardens is not optional. It’s the difference between a tenant who renews and a unit that sits empty.
Material Selection for Valley Conditions
We spec materials for the western Inland Empire valley floor: hot-dip galvanized or stainless fasteners, sealed slab-to-plate joints, James Hardie siding, and aluminum or vinyl window frames rated for high-heat sun exposure. The cheap inland spec fails here. We don’t install it.
Trusted Brands We Service in Home Gardens
We work hands-on with leading prefab ADU manufacturers and materials suppliers that match Home Gardens lots, budgets, and timelines. That includes Abodu, Cover, and Dvele. If you’re considering a prefab or modular ADU on a Home Gardens lot, we can help you choose the right manufacturer for your setback, your soil, and your county permit pathway. We also specify James Hardie siding for the valley’s heat cycling and seasonal moisture, because that’s the material that holds up on a Home Gardens detached conversion. Fast turnaround on parts and materials for Home Gardens customers comes through our established supplier relationships, not a big-box shelf hunt.
Common ADU Builders Problems We See in Home Gardens Homes
- The Corona detour. Homeowners walk into the City of Corona’s permit counter, get turned away, and lose two or three weeks before landing at the Riverside County Planning and Building & Safety offices. Contractors who skip the county FAST portal and the unincorporated-area pre-app checklist stall the same way. We start in the right place from day one.
- The 100-amp panel gap. Most Home Gardens homes built between the late 1940s and the 1960s carry 100-amp main service. An ADU with independent cooling, lighting, and appliances won’t fit on that panel. The main service upgrade must be part of the original scope, not a change order later.
- Rusted garage framing from old moisture. Detached garages in Home Gardens have decades of seasonal moisture trapped in untreated lumber and drywall-grade fasteners. By the time we open the walls, the hardware is often corroded. We re-frame with galvanized steel studs and stainless fasteners so the shell doesn’t fail again.
- No dedicated cooling scope. A garage-conversion ADU left on the house’s existing HVAC can’t hold temperature in Home Gardens summers. Riverside County plan review flags it, and even if it slipped through, no tenant stays through July. Dedicated mini-split cooling is a design requirement here, not an upsell.
Pricing for ADU Builders in Home Gardens, CA
Real numbers, because you shouldn’t have to call just to get a ballpark. A detached ADU in Home Gardens typically runs $180,000 to $320,000 depending on size, finish level, and whether the lot needs significant site work.

FAQs About ADU Builders in Home Gardens
Riverside County. Home Gardens is an unincorporated community governed by Riverside County, not an incorporated city, so every ADU permit routes through Riverside County Building & Safety. You do not go to the City of Corona’s permit counter, and you do not use a municipal submittal. We open the county’s FAST online portal and route through the unincorporated-area ADU pre-app checklist from the first submittal, which keeps the project from stalling. Call (254) 602-5618 and we’ll walk you through the exact pathway for your lot.
A 100-amp panel will not carry a Home Gardens ADU with dedicated mini-split cooling, lighting, and appliances. You need a main service upgrade to 200 amps before the ADU can be energized. The upgrade typically adds $4,000 to $8,000 to the project, and Riverside County plan review will flag it if it’s missing from the original scope. We include it in the written price from the start.
Yes. A garage-conversion ADU in Home Gardens needs its own dedicated cooling system, sized for the square footage and the valley’s summer heat. Sharing the main house’s HVAC fails county plan review and leaves the unit unrentable when summer highs top 100°F. We specify dedicated ducted mini-splits on every Home Gardens garage conversion.
We specify hot-dip galvanized or stainless fasteners, sealed slab-to-plate joints, James Hardie siding, and aluminum or vinyl window frames rated for the western Inland Empire valley’s heat cycling and seasonal moisture. The standard big-box package uses drywall-grade screws and untreated framing, which rust and fail early on Home Gardens detached garages. We don’t install the cheap spec because it costs more within a decade. Call (254) 602-5618 for a written materials list specific to your project.
The post-WWII detached garages in Home Gardens were built as single-car storage, not living space. The original slab, framing, and electrical were never meant to support a dwelling. Riverside County’s unincorporated-area ADU checklist treats that existing slab and framing as a plan-review item, which means we have to verify and often upgrade the shell before we design the interior. The west-facing garage door openings also tend to carry untreated lumber and corroded fasteners from decades of seasonal moisture, so we re-frame with galvanized steel studs and stainless hardware. Call (254) 602-5618 and we’ll inspect your garage and give you a written scope of work.
