Call (559) 354-0579 for a free, written estimate. Our crew knows Kerman’s streets, its older lots, and exactly what city reviewers ask for.
Kerman is a farm town, and that shapes how additions work here. Lots on the older grid, many from the 1950s through the 1980s, sit wide and flat with detached garages set back farther than you’d see in Fresno. Newer subdivisions north of town have their own HOA rules that can overrule the city’s already-light design review. We work both worlds, and we file every submittal ourselves so the review clock never starts without you.
The team at Home Addition Contractor in Kerman serves the whole city, from the neighborhoods off Madera Avenue to the newer subdivisions east of Highway 145. When you call, a live person answers. Always. That’s the Kingswell way, and it’s been that way since 2010.
Why Lodgewick ADU Fresno Is Kerman’s Preferred Home Addition Contractor Company
Kerman homeowners tell us the same thing over and over: the last contractor gave them a number, then the price moved. Ours doesn’t. We hand you a written price before any work starts, and that number doesn’t change at the door. That’s not marketing. It’s The Kingswell Guarantee, and it comes in writing on every project, including your home addition in Kerman.
Russ Delmar leads our crew, and he’s the one who answers for the work if something isn’t right. Not a call center. Not a revolving door of project managers. When we say we’ll show up in a defined arrival window, we mean a real block of time, not “sometime Tuesday.” And if the work fails within the 365-Day Done Right Promise period, we come back and make it right, free. That promise is written into every Kerman contract.
We’ve done enough work in Kerman to know that the city’s staff-level reviewers move fast when the submittal is clean. That’s the thing we bring to the table. We know what they flag, what they approve, and how to sequence the job so you’re not sitting with a half-gutted garage waiting on a plan check.
Our crew is background-checked and uniformed. You’ll know exactly who is on your property, and they’ll leave the job site cleaner than they found it. That’s The Kingswell Way: say the price before the work, show up in the window given, put the guarantee in writing, and come back if it fails.

Garage Addition Contractors in Kerman
Garage Addition Contractors in Kerman work on a specific kind of project: turning a detached garage, usually built in the 1960s or 1970s, into year-round living space. In Kerman, a garage conversion typically runs $95,000 to $160,000, and the spread comes down to what’s hiding in the slab and the electrical panel. Most of these older garages were never built for habitation, so the work involves footings, insulation, drywall, HVAC, and bringing the service up to code.
A lodge is a small house on a larger property, and that’s exactly what a converted Kerman garage becomes. We see homeowners do this for aging parents, grown kids, or rental income from the nearby agricultural workforce. The city’s ADU rules make Kerman one of the easiest places in Fresno County to pull this off, and our ADU Builders - Kerman team knows them inside and out.
Footings and Slab Remediation
The single most common issue we find in Kerman garage conversions is a slab with no perimeter footing. These garages were poured as a flat pad, and adding walls or converting to living space requires cutting the slab edge and pouring a thickened-edge footing. We do that in-house, so the city’s plan checker sees a complete drainage and structural package the first time, not a revision request.
Electrical Service Upgrades
Kerman garages from the 1960s often carry 60-amp aluminum subpanels that can’t handle a new kitchen or bathroom. Upgrading to 100 amps or more is usually part of the job, and we price it into the written estimate up front. No surprise line item when the panel gets opened.
Bathroom Addition Contractor in Kerman
A Bathroom Addition Contractor in Kerman handles two distinct projects: adding a full bath to a home that has too few, or building the bathroom inside a new ADU or garage conversion. A three-piece bathroom addition in Kerman generally runs $38,000 to $65,000 when tied to an existing home, and $28,000 to $45,000 when it’s part of a garage conversion where plumbing walls are already open. The final number depends on whether the home sits on a raised foundation or slab, and how far the new drain line has to run.
Kerman’s flat terrain and heavy clay soil mean drain lines have to be graded carefully. A bathroom on the far side of a detached garage needs a longer run, and sometimes a pump. We plan that before the first trench is cut.
Slab-On-Grade Bath Additions
Most Kerman homes built from the 1950s onward sit on slabs, so adding a bath means saw-cutting concrete to reach the drain line. It’s noisy work, but it’s predictable. We map the existing plumbing before we cut, and we keep the dust contained with proper barriers. Your home stays livable.
Bath Inside a Garage Conversion
When the bath is part of a garage conversion, the plumbing rough-in happens while the walls are open, which keeps costs lower than a standalone bath addition. We coordinate the venting and wet-wall placement with the city’s plan check so the submittal clears without a correction cycle.
Trusted Brands We Service in Kerman
We work with established ADU brands and materials that hold up in Kerman’s hot, dry summers and occasional winter tule fog. That includes Dvele and Cover for prefabricated units where the lot and budget fit, and James Hardie fiber cement siding for exterior finishes that don’t warp or fade in triple-digit heat. We also stock the fasteners, flashing, and touch-up materials for these systems locally, so a warranty follow-up in Kerman doesn’t mean waiting on a shipment from out of state. If something fails inside the guarantee window, we’re back on your street with the right parts.
Common Home Addition Contractor Problems We See in Kerman Homes
- Unpermitted 1960s garage additions. We’ve walked onto Kerman properties where a garage was extended decades ago without permits, and the original slab has no footing. That means the whole structure has to be remediated before the new addition can tie in, which adds cost and time but keeps your home legal.
- Submittals bounced for missing drainage swales. Kerman’s flat terrain means stormwater needs somewhere to go. City plan check regularly flags site plans that don’t show swales or grading, and that one item can cost weeks in review time.
- Rear-yard setback violations from older garages. A 1962 detached garage on Madera Avenue we converted sat 3 feet off the rear property line, not the 4 feet the city requires for an ADU. Had we missed that on the site plan, the submittal would have been rejected before review even started.
- HOA color and materials conflicts in newer subdivisions. Kerman’s newer developments, like those off Church Avenue, have their own architectural standards that can restrict exterior finishes beyond what the city requires. We check both rulebooks before you buy materials.

FAQs About Home Addition Contractor in Kerman
No. Standard ADU additions on Kerman R-1 lots go through staff-level review, not a separate architectural committee. As long as the site plan shows setbacks, drainage, and materials clearly, approval typically clears in 10 – 14 business days. That’s faster than Fresno or Clovis, where design review can add weeks. Call (559) 354-0579 and we’ll file a submittal that doesn’t bounce.
Kerman’s staff-level reviewers accept fiber cement lap siding like James Hardie in light, low-reflectance colors, stucco in earth tones, and composite or asphalt shingle roofing in darker neutrals. Dark stucco with a metal roof can trigger a solar reflectance condition in R-1 zones, which means a re-color before final approval. We check your exterior selection against current city guidance before you buy materials, so you don’t get a conditional approval that forces a change.
Plan check adds 10 – 14 business days for a complete submittal on a standard garage conversion. We file the submittal ourselves, including site plans, structural calcs, and drainage drawings. Corrections usually come from missing items, not design objections, so a clean submittal is the difference between a two-week review and a two-month stall. We know what Kerman’s reviewers ask for, and we front-load it.
Yes. We sequence the job so demolition doesn’t start until the city has cleared the permit. For a project with unpermitted work, that means we survey, draw, and submit first, then schedule the foundation remediation and framing to start only after approval is back. Your home isn’t left with a gutted garage and a fence around it while the city deliberates. Call (559) 354-0579 and we’ll walk the property and give you the real timeline.
No. Kerman does not currently assess impact fees on ADUs under 750 square feet, which is one reason this city is among the easiest places in Fresno County to add a rental unit. The absence of impact fees saves you $4,000 – $12,000 compared to neighboring cities and removes a step from the permit process, so your schedule doesn’t slow down waiting on a fee calculation. We confirm fee schedules at submittal so there are no surprises later.
