Get your free estimateFast, Reliable ADU Builders Across Selma
Adding an ADU in Selma usually means one of two things: converting a detached garage from the 1920s through 1950s, or building new on a standard 50′ x 100′ lot with rear alley access. Either way, you need a builder who knows what Selma’s older housing stock actually hides behind those stucco walls. We’re ADU Builders who work the historic grid districts off Rose Avenue, McCall Avenue, and Floral Avenue weekly. The foundations, the wiring, the setbacks – we’ve seen it all, and we’ll tell you the truth about what it costs before you sign anything. Call (559) 785-0627 for a free estimate and a written price, no vague ranges and no surprises later.
Why Sutton ADU Fresno Is Selma’s Preferred ADU Builders Company

Selma homeowners tell us the same thing over and over: other builders gave them a handshake and a ballpark, then the change orders started. That doesn’t happen on a Sutton project. You get a written price locked before the first tool is lifted, governed by the Threshold Standard – the same standard that requires every crew member to be background-checked, identity-verified, and photo-badged. Their name and photo come to you before they arrive at your door. Not a crew of strangers. A named, verified person in a marked uniform.
Our founder, Miles Hartwell, built Sutton ADU Fresno around one idea: a homeowner should never have to wonder who’s walking up the driveway. Selma customers get exactly that, plus the 365-Day Done Right Promise – a written guarantee covering workmanship for one full calendar year from completion. If something isn’t right, we make it right. No haggling, no forms, no fee for the second visit. That’s not a verbal assurance. It’s stamped on your contract.
Scheduling and dispatch run through our Fresno, Central Valley office, but crews serve Selma directly and know the local inspection quirks, the soil conditions, and the way older garages on Mountain View Avenue or Young Street tend to be framed. That local knowledge matters when a permit triggers code upgrades you didn’t know were coming.
JADU in Selma
A JADU in Selma is a Junior Accessory Dwelling Unit – a separate living space created within the walls of an existing single-family home, typically 500 square feet or smaller, with its own entrance, kitchenette, and bathroom. For Selma homeowners with an underused attached room, a daylight basement, or an oversized attached garage bay, a JADU is often the fastest and least expensive path to a rental unit or a private space for an aging parent. Because it uses the existing footprint, you skip much of the site work and foundation engineering that a detached ADU demands.
Most JADUs in Selma run $80,000 – $150,000, depending on whether the space already has plumbing rough-ins, adequate electrical service, and a legal egress window. If the walls are full of knob-and-tube and the panel is a 60-amp relic from the Eisenhower era, expect the number to climb – and expect us to tell you that before you sign, not after the drywall comes down.
Code triggers in older Selma homes
Opening walls in a 1940s Selma house almost always triggers a series of code upgrades: AFCI/GFCI circuits, hardwired smoke and CO detectors, and sometimes a full service panel swap from 60 or 100 amps to 200. We write an allowance for these into the contract, not a blank space. You’ll see the line item. You’ll know the range. No surprises.
Keeping the main house untouched
A JADU lets you add livable square footage and rental income without moving walls in the rest of the home. The main house stays occupied, the front yard stays intact, and the project stays contained. For homeowners in Selma’s historic grid who want income without a second structure, this is often the move.
ADU Plans in Selma

ADU Plans in Selma are the stamped architectural and structural drawings the city requires before you pull a permit – and on a mid-century lot with rear alley access and strict setback rules, those plans are not optional paperwork. They define how the structure sits on the lot, how utilities are separated, where the egress windows go, and how the foundation ties into the existing grade. In Selma’s historic grid districts, where many pre-1950 garages sit on non-conforming pier-and-beam foundations, the plan set also tells the foundation engineer exactly what’s needed to meet current seismic and frost-depth requirements.
Full ADU plan sets for a Selma project typically run $8,000 – $15,000, including structural engineering and city review. That’s not a markup; it’s the cost of drawings that won’t get kicked back by the Selma building department. We handle the entire plan process in-house or through engineers we’ve worked with on dozens of Selma sites – no homeowner left to chase a stamp on their own.
Setback and alley-loading realities
Selma’s standard 50′ x 100′ lots with rear alley access often force alley-loaded designs, where the ADU’s primary entrance and utility connections face the alley rather than the street. That changes where the water line stubs, how the gas meter is placed, and how the fire department will access the unit. Our plan sets account for all of it before the first trench is dug.
Frost, seismic, and soil
Selma’s occasional winter frost and Central Valley seismic requirements mean your foundation depth and reinforcement details have to be right on paper before concrete is poured. We specify footing depth, rebar schedule, and anchoring on every plan. The city checks. We make sure it passes.
Trusted Brands We Service in Selma
We install and service ADUs from Cover, Dvele, and Mighty Buildings across Selma. Each brand has different strengths: Dvele for high-performance panels, Mighty Buildings for fast panelized walls, Cover for precision-built modules. When a Selma homeowner asks which one fits their lot and budget, we give an honest answer based on your setback rules, your soil, and what you plan to do with the unit – not which brand pays a bigger kickback. We also work with James Hardie exterior systems for custom builds, and we keep the most common Selma-specific parts and materials staged locally so a project doesn’t stall waiting on a truck from Sacramento.
Common ADU Builders Problems We See in Selma Homes
- Non-conforming pier-and-beam foundations. In Selma’s historic grid districts, many pre-1950 detached garages sit on shallow pier-and-beam footings that don’t meet current frost-depth or seismic requirements. Unlike Fowler or Kingsburg, where slab-on-grade was common by the 1960s, Selma’s older garages almost always need a full foundation upgrade before conversion.
- Knob-and-tube wiring spliced into modern Romex. We find this in at least half the older Selma garages we open up. It’s not just a code issue – it’s a fire risk. A permit and a proper rewire are mandatory, not optional.
- Rafters notched and weakened by decades of DIY attic access. Older Selma garages frequently have roof framing that was structurally compromised long before we arrived. Sistering rafters or replacing sheathing adds real cost – and it’s exactly the kind of thing a vague estimate leaves out.
- Low ceiling heights that trip fire separation and egress rules. Many 1950s Selma garages have 7’6″ or 8′ ceilings that won’t clear the city’s minimum for habitable space. A plan that assumes standard height gets rejected, which is why we measure and verify before we draw.
Pricing for ADU Builders in Selma, CA
Let’s talk real numbers for Selma. A detached ADU conversion from a mid-century garage runs $220,000 – $380,000 when the foundation needs a full upgrade – which it usually does in the historic grid. A ground-up detached ADU on a standard 50′ x 100′ Selma lot runs $250,000 – $450,000 depending on size, finishes, and utility trenching. A JADU inside the existing home runs $80,000 – $150,000. Those are honest ranges based on what we’ve built here, not national averages. The single biggest cost driver in Selma is the foundation work on older garages, and second is the panel and rewiring upgrade. We write both into your contract as explicit allowances with dollar ranges you approve before we ever open a wall. Call (559) 785-0627 for a free estimate and a written price – not a ballpark, not a handshake.

FAQs About ADU Builders in Selma
Most 1930s – 1950s Selma garages sit on pier-and-beam foundations with inadequate footing depth for current frost and seismic codes, so a full foundation upgrade – typically $30,000 – $60,000 – is the norm, not the exception. Unlike Fowler or Kingsburg where slab-on-grade arrived earlier, Selma’s older stock almost always triggers this. We write an allowance for it into your contract so the number doesn’t hit you after demo. Call (559) 785-0627 for a site-specific foundation assessment.
In many cases, yes – on Selma’s standard 50′ x 100′ lots with rear alley access, the city’s setback and utility separation requirements often push the ADU entrance and service connections toward the alley rather than the street. This changes where water, gas, and power stubs go, and it’s why we verify the exact requirements for your specific lot before we draw plans. Call (559) 785-0627 and we’ll walk your property with the current Selma setback rules in hand.
Expect a full rewire if knob-and-tube is present (mandatory, not optional), a panel upgrade to at least 200 amps, hardwired smoke and CO detectors, and possibly structural repairs to rafters or sheathing. On a 1948 Rose Avenue garage, we found knob-and-tube spliced into modern Romex and rafters notched to half their depth – both were fixed, documented, and approved in writing before the next phase. Call (559) 785-0627 for a free inspection of what your garage is actually hiding.
Yes – a garage-to-JADU conversion stays entirely within the existing detached structure, so the main house remains occupied and untouched throughout the project. This is the fastest, least disruptive path to a rental unit on a Selma lot, and it avoids most site work. Expect $80,000 – $150,000 depending on foundation condition and electrical scope. Call (559) 785-0627 to get a written price for your specific garage.
We stop, document it with photos and a written scope, and present you a fixed price for the repair before we do anything else. There’s no silent scope creep – the 365-Day Done Right Promise and the Threshold Standard mean the fix is priced and approved in writing first. Often we’re replacing failed sheathing, sistering rafters, and adding a James Hardie rainscreen assembly, exactly as we did on that Rose Avenue garage. Call (559) 785-0627 for a free estimate.
Adding an ADU in Selma shouldn’t mean opening your home to strangers or to a contract full of blank spaces. Call (559) 785-0627 and we’ll send a named, photo-badged technician to walk your property, measure your garage, and give you a written price – free, clear, and locked before the first tool is lifted.
