Adding square footage to a Clovis home usually costs between $180 and $420 per square foot, depending on whether you’re building out, building up, or converting existing space. A bump-out addition in a 1990s tract home off Shepherd Avenue might run $45,000 to $85,000, while a full second story in the same neighborhood often lands between $140,000 and $260,000. Those are real numbers we quote every week, and we put them in writing before any work begins. Call (559) 206-2363 to schedule a free estimate with our Home Addition Contractor team serving Clovis.
We know Clovis homes differently than a contractor who drives up from Fresno for a bid. The 1990s-2000s tract stock, the east-side subdivisions built on former farmland, the older pockets near Old Town with their smaller setbacks. None of it surprises us anymore. What surprises homeowners is what opening a wall actually reveals. We handle that with a process built for transparency.
Why Benson ADU Fresno Is Clovis’s Preferred Home Addition Contractor Company
Homeowners across Clovis call us because we answer the phone, show up in uniform, and hand over a written price instead of a verbal guess. Troy Eastman leads our Clovis projects with a simple rule: if something on a job changes, the price change goes to you in writing before we touch it. No scope creep billed after the fact. That discipline matters most in older Clovis homes, where one opened wall can rewrite the budget if nobody planned for it.
Our local reputation is built on handling those surprises well. We’ve worked in the Harlan Ranch area, the neighborhoods around Buchanan High School, and the older blocks west of Clovis Avenue. Each zone has its own building quirks. We know which tract home years used aluminum wiring, which subdivisions sit on expansive clay soil that shifts footings, and which original stucco jobs have failing window flashings. That local knowledge goes into every estimate we write.
Dispatch and scheduling for our Clovis crews are coordinated from our Fresno, Central Valley office. Homeowners here get a live arrival time, background-checked technicians on site, and before-and-after photos of the work. You’ll know who is walking onto your property and exactly what they’ll do that day.
Second Story Addition Contractor in Clovis
A second story addition contractor in Clovis takes on the most structurally demanding type of residential expansion: lifting the roof, reinforcing the existing frame, and building upward on a home that was never designed for a second level. Homeowners in northeast Clovis pursue this when their lot won’t support a wide first-floor addition, or when a growing family needs bedrooms without giving up the backyard. The trade-off is cost and complexity. Expect $140,000 to $260,000 for a full second story on a typical 1990s tract home, with the structural retrofit driving much of the price.
Structural Concerns With 1990s Tract Homes
Most homes built in Clovis during the 1990s and 2000s used the minimum framing required at the time. That means undersized headers, 2×4 exterior walls on some builds, and footings sized for a single story. Adding a second level requires an engineer to evaluate what the existing foundation and frame can actually carry. We handle that evaluation before any pricing is finalized, not after demolition starts.
What the Permit Triggers
Here’s what nobody tells you at the kitchen table estimate: opening your framing for a second story triggers a permit review against today’s Title 24 energy code and current structural amendments in Clovis. The original home met the standards of its build year. The addition must meet 2026 standards. That covers insulation, window efficiency, smoke and carbon monoxide placement, and in many cases upgraded electrical panels. We write these improvements into your contract as line items so the price doesn’t shift mid-project.
Garage Addition Contractors in Clovis
Garage addition contractors in Clovis build living space where a car used to park. That might mean a new attached garage with a room above it, or converting an existing garage into a bedroom suite, rental unit, or workshop. For lots in the 7,000 to 10,000 sq ft range that dominate east Clovis, a garage addition often works where a detached ADU Builders - Clovis project won’t fit under the setback rules. Typical garage additions here run $40,000 to $95,000 depending on whether you’re converting, extending, or building from the slab up.
Garage Conversions in Older Areas
Near Old Town Clovis, lots are tighter and homes are older. We see 1980s builds with original garage slabs that slope toward the house, single-layer foundations, and electrical panels that predate AFCI requirements. Converting these garages means bringing the space up to current code: insulation, proper egress windows if it becomes a bedroom, and dedicated circuits. It’s doable, but you want a contractor who has done it before.
New Garage Additions in East Clovis
In the newer subdivisions east of Clovis Avenue, a detached garage addition is often the fastest structural expansion available. The slab is straightforward, the trusses are pre-engineered, and the design avoids the frame surgery that a second story requires. We still inspect the existing structure where the new garage ties in, because that’s where water intrusion and framing gaps show up years later.
Trusted Brands We Service in Clovis
We don’t ask Clovis homeowners to take our word about product quality. We build with brands you can research on your own, including Cover, Dvele, and Mighty Buildings for prefab panels and factory-built components. For additions that need speed and predictable pricing, prefab panels arrive engineered, measured, and ready for assembly, which shortens the on-site framing phase. For traditional site-built additions, we source James Hardie cladding and standard structural materials suited to Clovis’s dry, hot climate. You get options with named brands behind them, not a single take-it-or-leave-it product.
Common Home Addition Contractor Problems We See in Clovis Homes
- Aluminum wiring from 1980s builds. Homes near Old Town and the west side of Clovis often still have original aluminum branch circuits. Opening a wall means the inspector sees it, and code requires remediation before we can close the wall back up.
- Failed stucco waterproofing. Clovis’s dry climate hides slow water intrusion behind original stucco for years. Once we remove an exterior wall, rot from a failed window flashing or a cracked stucco seam becomes visible, and the framing repair gets added as a written change order.
- Undersized 2×4 framing that has bowed. Decades of 100°F summers take a toll on exterior walls built with minimum framing. In a 1990s tract home near the Clovis East High School area, our tech opened a den wall to enlarge it into a bedroom and found undersized 2×4 framing that had bowed, plus aluminum wiring from the original build. We wrote a change order for upgraded 2×6 framing and a new AFCI-protected circuit, then got homeowner approval in writing before proceeding.
- Short-cycling HVAC in oversized additions. When someone adds 500 sq ft and a contractor slaps in a bigger air conditioner without running a load calculation for Clovis’s 100°F design temperature, the system cools the space too fast, shuts off, and turns back on constantly. The humidity never gets pulled out, and the electric bill climbs. We size HVAC to the addition’s actual load, not a rule of thumb.

FAQs About Home Addition Contractor in Clovis
Expect the inspector to require bringing the opened area up to current Title 24 energy standards, which means upgraded insulation, efficient windows, and proper sealing. Depending on the build year, you may also need AFCI circuit breakers, improved smoke and carbon monoxide detection, and sometimes a panel upgrade. We write these into your contract before we open the wall, so they don’t arrive as a surprise line item later. Call (559) 206-2363 for a quote that accounts for these upgrades from day one.
We inspect the exposed framing the moment the wall comes off, not after demo is finished. If rot or failed waterproofing shows up, we photograph it, write a change order with a fixed dollar amount, and get your written approval before we repair it. You never owe for work you didn’t approve in writing. That’s how our Home Addition Contractor crew has handled every Clovis exterior wall removal we’ve done, and it’s the same process on yours.
The inspector will flag it, and code requires mitigation before we can close the wall. That typically means replacing the aluminum branch circuits feeding the area or installing proper aluminum-to-copper connections at every junction. We include an electrical allowance in our initial quote for older Clovis homes so that if we find aluminum wiring, the cost is already anticipated. Call (559) 206-2363 for an estimate with that allowance built in.
In most cases, yes, but it depends on what the existing footings and frame were actually built with. Many 1990s Clovis tract homes used 2×4 exterior walls and minimum-size footings that cannot carry a second floor without reinforcement. An engineer’s evaluation will tell you exactly what’s needed, and we won’t price a second story without that report. If the foundation needs upgrading, we’ll quote it as a separate line item in writing before anything starts.
We run a Manual J load calculation based on the addition’s square footage, window exposure, insulation, and Clovis’s design temperature, not a generic “one ton per 500 sq ft” guess. An oversized unit short-cycles, which drives up cooling costs and leaves humidity in the air. A properly sized unit runs longer cycles, pulls moisture out, and costs less to operate through a Clovis summer. It’s part of every addition we quote.
