Why Lodgewick ADU Fresno Is Fresno’s Preferred Garage Conversion Contractor Company

We started in 2010 as part of the Kingswell family of home-service companies, and the Fresno office works exclusively in the Central Valley. Russ Delmar leads our Fresno crew, and he’s walked more post-war ranch houses and open-acreage lots in this market than most contractors will see in a decade. When a homeowner off Herndon Avenue asks whether their 1970s attached garage can support a second-story addition, our team knows exactly what the city’s building department will flag before we even open the plans.
Everything we commit to goes on paper before work starts. That’s The Kingswell Guarantee: a written price, a defined arrival window, a clean job site, and a written guarantee on every build. If something isn’t done right within 365 days, we come back and make it right. No charge. That promise is delivered in writing on every project, before a single nail is driven. Fresno homeowners who’ve been burned by contractors who vanish after final payment tell us that guarantee is why they chose us.
Our crews are background-checked and uniformed, so you always know who’s on your property. And when you call with a question mid-build, a live person answers. Russ or a member of his team, 24 hours a day, 7 days a week. That matters when you’re living through a conversion and something comes up at 6 a.m. before the crew arrives.
Garage Apartment Conversion in Fresno
A Garage Conversion Contractor takes an existing garage shell and turns it into a legal, livable apartment: insulation, drywall, plumbing, electrical, a bathroom, a kitchenette, and separate access. In Fresno, this is one of the fastest ways to add rental income or a place for aging parents, because the structure already exists and the roof is already tied to the house or standing on its own. What most homeowners don’t realize is how much of the final cost gets decided by what’s under the slab and behind the walls. A 1960s garage in the Tower District may hide knob-and-tube remnants that trigger a full rewire, while a detached garage on two acres near Ashlan Avenue may need a new septic leach field before the county will even look at the building plans.
Heavy-Up and Panel Work
Most Fresno garages were originally wired for a light bulb and maybe a garage-door opener. Turning one into an apartment means a subpanel, dedicated circuits for a kitchen and bath, and often a 200-amp main panel upgrade at the house. Older Fresno homes from the 1950s and 1960s frequently still run on 100-amp service, and that upgrade alone can add $4,000 to $7,000 before any finish work begins.
Separation and Egress
A legal garage apartment in Fresno needs its own exterior door, an egress-compliant bedroom window, and fire separation between the unit and any remaining garage space or the main house. On city lots, that’s usually straightforward. On county acreage, fire separation requirements can conflict with septic setbacks, which is exactly where our scoping work saves homeowners from surprise redesign fees.
Garage Conversion Permit in Fresno

A Garage Conversion Permit in Fresno is not a flat-fee form; it’s a plan review that differs sharply between the City of Fresno and unincorporated Fresno County. City permits for a standard attached conversion typically run $3,500 to $6,500 in fees, while county permits on acreage lots routinely range from $6,000 to $11,000 once Environmental Health reviews are included. The single most expensive mistake we see on acreage is a homeowner or out-of-area contractor assuming city rules apply. They don’t. Fresno County requires septic and private well setback approval before building permits are issued, and that review can force a complete redesign of where the bathroom sits in your future ADU.
Environmental Health Review
Fresno County Environmental Health requires 100 feet of separation between any septic system and a private drinking water well. If your existing well sits 40 or 60 feet from the garage, the bathroom can’t go where you thought it would. Sometimes the fix is a new leach field on the far side of the lot. Sometimes it’s a holding tank upgrade. Either way, it’s a five-figure scope item that should be identified during quoting, not discovered after demolition.
Setback and Grading Approvals
County projects often need a grading and drainage plan submitted alongside the building plans. On open lots, that usually means a civil engineer’s stamp, compacted fill specifications, and a drainage swale or retention basin detail. We pull permits and submit plans on every project, and we walk each homeowner through what the county is asking for and why. No change orders at the door. The price we put in writing is the price we build to.
Trusted Brands We Service in Fresno
We work regularly with materials and systems from James Hardie, whose fiber-cement siding handles Fresno’s 110°F summers without warping, and from Cover and Abodu when a homeowner wants a panelized or prefab component to cut framing time. For detached conversions on acreage, we also have hands-on familiarity with Dvele and Mighty Buildings envelope systems that arrive pre-insulated. Because we stock common trim, flashing, and hardie-backer locally for Fresno customers, material lead times stay short even when supply chains tighten in the Valley.
Common Garage Conversion Contractor Problems We See in Fresno Homes
- Septic and well setback surprises. A garage on unincorporated county land looks like an easy conversion until Environmental Health measures the distance from the well cap to the proposed bathroom and rejects the layout. We scope this before quoting.
- Underbuilt slabs and footings. Many Fresno garages built between the 1950s and 1980s sit on 3-inch slabs with no stem walls. Adding living space means cutting and pouring new footings, which a lowball bidder conveniently leaves out of the estimate.
- Heat-driven material failure. Standard studs and trusses left exposed during a Fresno summer will warp and crack before drywall goes up. We plan material delivery and staging around the heat, not against it.
- Access constraints on acreage. A long, narrow driveway that handles a pickup truck won’t support a concrete pump or a 30-yard roll-off. We grade compacted gravel access paths before heavy equipment ever arrives.
Pricing for Garage Conversion Contractor in Fresno, CA
On a city lot in Fresno, an attached garage conversion to a one-bedroom ADU runs $85,000 to $145,000 depending on panel upgrades, bathroom location, and finish level. Detached conversions on acreage typically run $120,000 to $190,000, and the difference is almost always site work: septic redesign, well setbacks, grading, compacted fill, and longer hauls for materials and concrete. A garage apartment with a full kitchen and separate entry trends toward the top of each range. A simple garage-to-bedroom conversion with a half bath trends toward the bottom.

FAQs About Garage Conversion Contractor in Fresno
They can add $10,000 to $30,000 and several weeks of review before construction starts. Fresno County Environmental Health requires 100 feet of separation between a septic system and a private well, and if your garage sits closer than that to either, the bathroom layout has to move or the septic system has to be redesigned. Call (559) 354-0579 for an exact scope on your lot. Estimates are free.
Yes, in most cases. Unincorporated Fresno County typically requires a grading and drainage plan with the permit submittal, especially when the conversion changes the footprint of impervious surface or adds a new bathroom on septic. The plan usually needs a civil engineer’s stamp. We handle that submission as part of the job, and the cost is in the written price before work starts.
Because site work drives the cost. On acreage you’re usually paying for a septic review, possibly a new leach field, well setback compliance, compacted fill, a grading plan, and a longer haul for materials and concrete. A city lot conversion has none of those. The spread is typically $30,000 to $50,000. Call (559) 354-0579 and we’ll walk your property and tell you exactly which line items apply.
Yes. Fresno County enforces Title 24 energy standards, and in Climate Zone 13 that means a cool roof or equivalent heat-reflective roofing, plus attic insulation at R-38 or better. We scope roof and insulation to meet code the first time, so the conversion passes inspection without a redo. No surprises, no second trips on our dime.
We measure the distance between the garage, the shop, the well, and the septic system, then check whether any existing outbuilding already claims your allowed lot coverage or setbacks. On acreage, an existing shop sometimes affects where the conversion can expand or where a leach field can go. We factor all of that into the written price before you commit. Call (559) 354-0579 to schedule a site walk.
