Get your free estimateFast, Reliable ADU Builders Across Clovis
Most Clovis homeowners call us with the same question: what will an ADU actually cost, and how long until it’s done? Here’s the straight answer. A detached backyard ADU in Clovis runs roughly $220 – $350 per square foot all-in, meaning a 600-square-foot one-bedroom typically lands between $130,000 and $210,000. Prefab or modular units generally come in at the lower end. Garage conversions run $80,000 – $140,000. That’s the honest range for Clovis’s market right now, and we put every number in writing before any work starts. Call (559) 354-0579 and we’ll walk you through a real estimate for your lot.
The Clovis ADU boom isn’t an accident. The city has leaned into accessory dwelling units with pre-approved plans and a streamlined permitting process that moves faster than what homeowners across the line in Fresno deal with. That means less waiting and fewer surprises. Our crews drive Clovis streets every week, from the newer developments around Harlan Ranch to the established neighborhoods off Gettysburg and Peach. Russ Delmar leads our ADU team with fifteen years of residential construction experience, and he’s the one who reviews your site plan before a single permit gets pulled.
Why Lodgewick ADU Fresno Is Clovis’s Preferred ADU Builders Company
We’re the ADU Builders team Clovis homeowners call when they want the work scoped correctly the first time. The Kingswell family built this company in 2010 on a simple idea: write the price down before the work starts, show up when you say you will, and come back if anything isn’t right. That’s not marketing language. It’s The Kingswell Guarantee, and it’s on paper for every Clovis project we take.
Local homeowners tell us what went wrong with the last contractor. A price that changed at the door. A crew that vanished for two weeks. A finish that cracked after one summer. Clovis summers are brutal on bad construction, and we’ve seen the results: stucco that separates at the seams, undersized HVAC units that can’t hold 75 degrees in July, and insulation so thin the power bill doubles. Those failures are exactly what our 365-Day Done Right Promise exists to prevent. If the work isn’t right, we come back and make it right. That’s in writing.
Serving Clovis means knowing the tile roofs, the stucco exteriors, the big lots from the 1990s onward, and the alley-loaded subdivisions on the east side. It means knowing which plan checker at the building department asks for the extra energy calc. It means understanding that your neighbors off Willow and Nees don’t want a construction site parked in front of their house for six months. We coordinate from the Fresno Central Valley office, but our crews are in Clovis daily.
Backyard ADU in Clovis
A backyard ADU in Clovis is a detached living unit built in the rear yard of an existing single-family home, and it’s the most popular ADU type in this city for good reason: most Clovis lots are large enough to accommodate a 500-to-800-square-foot structure without sacrificing much usable yard. Homeowners in areas like the Buchanan High School corridor or the neighborhoods around Sierra Vista Mall often have 7,000 to 10,000 square foot lots, which gives real room to work with.
Expect a detached backyard ADU in Clovis to run $220 – $300 per square foot for standard construction, with prefab installations from manufacturers like Abodu or Cover landing closer to $180 – $250 per square foot installed. A 600-square-foot one-bedroom with a kitchen and bath typically falls between $130,000 and $180,000 depending on finishes, foundation type, and utility routing.
Detached ADU Siting and Access
Where the ADU sits on your lot changes everything about cost and schedule. A unit built in the open rear yard with street access for equipment is the simplest scenario. A unit tucked behind the house with no side yard access requires different material handling, which adds labor hours. We flag this in the written estimate so you’re not surprised later.
Foundation and Utility Runs
Clovis soil generally drains well and doesn’t present the expansive clay problems you see in other Central Valley cities, but we still compact and test every pad. Trenching for water, sewer, and electrical from the main house to the ADU is typically $8,000 – $15,000 depending on distance and whether we hit hardpan. We show that line item separately in every Clovis quote.
ADU Construction in Clovis
ADU construction in Clovis means building a permitted, code-compliant secondary dwelling on your existing property, whether it’s detached, attached, or a garage conversion. The process here moves faster than in neighboring Fresno because Clovis maintains pre-approved ADU plans and a permit review path designed for accessory dwellings. That’s a real advantage, and it translates to starting construction weeks sooner and carrying fewer months of architectural fees.
Full construction of a detached ADU in Clovis, from permit submission to final inspection, typically spans 5 to 8 months. Prefab installations can cut that to 3 to 5 months since the module is built offsite while site work proceeds. Custom builds with two stories, attached garages, or complex rooflines extend to 8 to 12 months. Russ Delmar walks every Clovis client through a realistic calendar before we sign anything.
Stucco and Tile Roof Matching
Most Clovis homes built since the 1990s wear stucco exteriors with concrete tile roofs. Matching those materials on a new ADU is not optional if the structure is visible from the street. We work with local stucco finishers who can match texture and color closely enough that neighbors can’t tell where the original house ends and the ADU begins. James Hardie siding is another option we recommend on east-side lots where fire resistance matters more.
Title 24 and Cooling Loads
Clovis regularly hits 100 degrees in July and August, and the city enforces California’s Title 24 energy standards strictly on new ADUs. We size the mini-split or HVAC system for the actual cooling load of the unit’s square footage, orientation, and glazing, not a rule-of-thumb number. Skimping here is the most common mistake we see on ADUs built by other contractors, and the result is a unit that can’t hold temperature after 2 p.m. in August.
Trusted Brands We Service in Clovis
For Clovis homeowners who want a faster path, we install and finish Clovis Abodu service and Cover prefab ADUs. These manufacturers produce quality modules in controlled factory conditions, which means fewer weather delays and tighter construction tolerances than many stick-built projects. For custom builds, we standardize on James Hardie siding for its fire resistance and durability in the Central Valley climate, and Dvele for high-performance prefab where budget allows. We stock common materials locally so Clovis projects don’t stall waiting on a shipment.
Common ADU Builders Problems We See in Clovis Homes
- Undersized cooling systems. A contractor installs a 1-ton mini-split on a 600-square-foot ADU with west-facing windows, and by August the unit runs all day and still hits 82 degrees inside. Title 24 compliance requires proper load calculations, and we do them on every Clovis build.
- Alley-access surprises. On east-side lots near Clovis East High School, builders price a rear-alley ADU like a standard backyard build, then discover the utility trenching and alley access for concrete trucks adds $12,000 – $20,000. We identify alley-load logistics before we quote.
- Pre-approved plan mismatch. A homeowner takes a Clovis pre-approved plan, makes custom changes, and no one clarifies which plan version actually applies. Plan check stalls for weeks, eating the streamlined timeline advantage. We manage plan revisions with the building department directly.
- Stucco and tile mismatch. The new ADU is finished in smooth stucco while the original house is a heavy knock-down texture, or the tile profile doesn’t match. It looks wrong from day one. We source matching materials from the same local suppliers that built the original homes.

A detached ADU in Clovis requires a building permit, a site plan review, and inspections at foundation, framing, rough electrical, rough plumbing, insulation, and final. Clovis offers pre-approved ADU plans that shorten plan check, but any custom changes must be reconciled with the city. We manage the full permit and inspection schedule on every Clovis build, and we don’t start work until permits are issued.
Clovis allows two-story ADUs up to the city’s height limits, typically around 16 to 25 feet depending on zoning and distance from property lines. Height limits, setbacks, and lot coverage rules vary by your specific parcel, so don’t assume a two-story unit will fit. We review your survey and zoning before recommending a floor plan, and we’ll tell you if a two-story design triggers extra engineering or fire-safety requirements on your lot.
Plan on 5 to 8 months for a standard stick-built detached ADU in Clovis, from permit submission to final inspection. Prefab units from Abodu or Cover typically run 3 to 5 months. Custom builds with two stories or complex rooflines run 8 to 12 months. Permitting in Clovis is faster than Fresno thanks to the city’s streamlined ADU process, but plan check typically adds 4 to 8 weeks. Call (559) 354-0579 and we’ll map a realistic schedule for your specific project.
The price you get from us before construction is the price you pay. That’s The Kingswell Guarantee in writing. What could change it: you decide mid-build to upgrade finishes, add square footage, or change the roofline. A pre-approved plan that gets modified after permit issue requires a revision and possible re-review. We flag every potential change and its cost before doing the work, in writing, every time. Call (559) 354-0579 for a free estimate and the guarantee in writing.
