Adding square footage to a Selma home usually costs between $85,000 and $240,000 depending on whether you’re bumping out a room, converting a garage, or going up with a second story. Most Selma homeowners call us because their family has outgrown the house but they don’t want to leave the neighborhood they love. We’re Sutton ADU Fresno, and our Home Addition Contractor team has walked through enough pre-1980 Selma garages to know exactly what’s behind those old walls before we ever write a quote. If you’re planning an addition anywhere in Selma, call (559) 785-0627 for a free estimate with a written price locked in before work starts.
Key Takeaways:
- Selma home additions typically run $85,000 – $240,000, with garage conversions on the lower end and second-story additions on the higher end.
- Pre-1980 Selma garages often sit on pier-and-beam foundations that need engineered footings before conversion, a cost neighbors in Fresno don’t always face.
- Every Sutton project includes a written price, a 365-Day Done Right Promise, and a photo-badged crew whose name you know before they arrive.
Why Sutton ADU Fresno Is Selma’s Preferred Home Addition Contractor Company
Selma homeowners call us because they want to know who’s walking onto their property before the door opens. That’s the Threshold Standard at work: every technician is background-checked, identity-verified, uniformed, and photo-badged. We send you the name and photo of whoever’s coming before they arrive. Not as a courtesy. As a rule.
Miles Hartwell leads our Selma projects, and he’s the one who walks your lot, inspects your existing structure, and puts the written price in your hand. Founded in 2006, Sutton ADU Builders has spent nearly two decades learning what older Central Valley homes actually need once walls come open. In Selma specifically, that means knowing which 1940s garages have knob-and-tube wiring, which alleys have setback issues, and which lots can support a second story without fighting the city.
We serve Selma from our Fresno-based Central Valley office, with crews dispatched locally. When you call (559) 785-0627, a live person answers, not a voicemail tree. That matters when you’re mid-project and need an answer right now.
Second Story Addition Contractor in Selma
A Second Story Addition Contractor in Selma handles the structural, electrical, and roofing work that turns a single-story ranch into a two-story home. This is the right move when your lot is too narrow to build out, which is common on Selma’s standard 50′ x 100′ parcels. Going up costs more per square foot than a bump-out, usually $120,000 – $240,000 before site work, because it requires engineering the existing first-floor walls and foundation to carry the new load.
What the engineering actually involves
Before we quote a second-story addition in Selma, we check the existing foundation, wall framing, and roof structure. Many mid-century Selma homes were built to hold a single story and a light roof. Adding a second floor often means adding shear walls, upgrading footing pads, and sometimes sistering the existing floor joists. We write all of this into the contract as line items, not as a vague “contingency” you find out about later.
How this works on a narrow Selma lot
When you can’t build sideways, up is the only answer. On a 50′ x 100′ lot near downtown Selma’s historic grid, setbacks leave little room for a ground-floor addition along the sides. A second story keeps your yard, keeps your garage, and gives you the bedrooms you need without eating the lot. The trade-off is more engineering and a longer permit review. We handle both.
Garage Addition Contractors in Selma
Garage Addition Contractors in Selma deal with one recurring reality: older detached garages here were never built to ADU or addition standards. In Selma, many pre-1980 garages sit on non-conforming pier-and-beam foundations, which, unlike the slab-on-grade garages common in neighboring Fowler or Kingsburg, must be upgraded to engineered footings before a conversion passes inspection. That’s an expense most quotes conveniently leave out. We don’t.
What a garage addition costs in Selma
A basic garage-to-living-space conversion in Selma runs $85,000 – $150,000, but the foundation upgrade alone can add $8,000 – $20,000 if the piers are undersized or the beams have rotted. We inspect first, then write the allowance into your contract. You know the number before we start, not after we open the floor.
The alley-loading factor
Many Selma lots have rear alley access, which is great for parking the cars but rough on utility routing. Converting a detached garage means separating utilities from the main house and often running new service lines from the alley side. If the alley wall has failed waterproofing, which we see often on 1940s garages, that repair gets documented and priced before we touch it, never after.
Trusted Brands We Service in Selma
We install and convert structures from Abodu, Cover, and Dvele, and we’re fluent with James Hardie exterior systems for additions that need to blend with an existing stucco or wood-sided Selma home. If you’ve been researching a prefab ADU kit, we can tell you honestly which product line fits a 50′ x 100′ Selma lot with alley access and which ones won’t clear the setback. We stock the common flashings, fasteners, and Hardie trim profiles for Selma jobs, so material lead times stay short and turnaround stays predictable.
Common Home Addition Contractor Problems We See in Selma Homes
- Pier-and-beam foundations under 1920s – 1950s garages. These were built for tool storage, not living space. Most need engineered footings and new floor framing before a permit will be issued, and that cost needs to be in the contract from day one.
- Knob-and-tube wiring hidden in ceilings. Selma homes from the 1930s and 1940s often still have active knob-and-tube runs above finished ceilings. Opening those walls for an addition triggers a code requirement to remove it and upgrade the panel, which is why we write an electrical allowance into every pre-1980 Selma quote.
- Failed waterproofing on alley-side walls. The rear wall of a detached garage faces the alley and takes decades of splashback and irrigation overspray. By the time we open it, the sill plate is often rotten and the studs are punky, and no amount of new drywall fixes that.
- Rear alley setback and utility separation conflicts. Converting a detached garage in Selma means meeting current setback and utility separation rules that didn’t exist when the garage was built. We design around the alley, not against it, and submit drawings that pass on the first review more often than not.

FAQs About Home Addition Contractor in Selma
We inspect first, then write a written allowance into your contract for the specific code upgrades the permit will trigger, which in Selma usually means panel replacement, structural sistering of undersized framing, and sometimes foundation work. If we open a wall and find something the inspection missed, we document it, show you photos, and get written approval on the price before we touch it. Call (559) 785-0627 and we’ll walk your lot the same week.
Pre-1980 Selma garages frequently sit on non-conforming pier-and-beam foundations with undersized piers and rotted sills, which must be upgraded to engineered footings before the conversion can pass inspection. That upgrade typically adds $8,000 – $20,000 to the project, and it should be in your contract from the first quote, not discovered as a “surprise” after demo. Call (559) 785-0627 to get a real foundation inspection before you commit.
Yes, a second-story addition in Selma always requires a building permit and structural engineering, because the existing walls and foundation must be proven capable of carrying the new load. We prepare the drawings, pull the permit, and handle the inspections as part of every project, with the permit fees written into the contract. Call (559) 785-0627 for a free estimate that includes permit expectations.
Selma’s rear alley access means your converted garage must maintain the setback from the alley right-of-way and separate its utilities from the main house, which often means routing new service lines from the alley side and upgrading the existing weatherhead. We design around those rules from the start so your drawings pass review instead of bouncing back for redesign. Call (559) 785-0627 and we’ll explain exactly how your lot’s alley affects your build.
For Selma’s hot, dry summers and occasional winter frost, we recommend a heat pump with a properly sized ductless or mini-split system, plus dual-pane windows and blown-in or spray-foam insulation rated for the Central Valley’s temperature swings. These upgrades run $12,000 – $22,000 depending on the addition’s size, and they’re written into the quote as line items, not added later. Call (559) 785-0627 for a free estimate with those numbers in writing.
Get a Written Price Before You Open a Single Wall
The biggest difference between us and a typical addition contractor is that you’ll know the price and the people before the work starts. The Threshold Standard means a written price, a 365-Day Done Right Promise covering workmanship for a full calendar year, and a free second visit if any element fails. It means the person at your door is background-checked, identity-verified, and photo-badged, and you already know their name. In Selma, where older homes hide wiring and foundation surprises, that level of clarity is worth more than any discount. Call (559) 785-0627 to schedule your free estimate. We’ll inspect your garage, your lot, and your plans, and hand you a written price before a single tool is lifted.
