Quick Answers About Clovis, CA ADUs
Market Context
Clovis has a median home value of $390,000. Adding an ADU typically increases that by 27% — approximately $105,300 in added equity. A 1-bedroom ADU in Clovis rents for approximately $1,365/month in the Fresno County rental market , yielding a 6.8% cap rate on the investment. Occupancy averages 95% in this market.
Top Clovis neighborhoods for ADU investment include Old Town Clovis, Tarpey Village, Sierra Bicentennial Park area, Harlan Ranch, Quail Lakes. Older single-family lots near downtown with strong rental demand and walkable amenities, ideal for ADUs. Large lots and established single-family homes increase potential for detached ADUs.
Permit Process
Permit applications are reviewed by the Building Division , with a plan check timeline of approximately 8 weeks. Permit fees in Clovis range from $3,500 to $12,000 depending on project scope. Design review: Yes - in historic districts only
Clovis's Building Division routes most ADU plans through their in-house structural review because of the Seismic Design Category D requirements here, and that review often kicks back projects for additional shear wall or foundation anchoring details that a standard prefab ADU package doesn't include out of the box. Older Clovis neighborhoods near Old Town and Sunnyside frequently have undersized electrical panels, so PG&E's service upgrade queue — not the city — becomes the real bottleneck, sometimes adding two to three months if a transformer upgrade is needed. Also, since Fresno County treats detached ADUs on septic-served lots as an added bedroom load, you'll likely need a septic capacity letter from the county Environmental Health department before Clovis will even log your permit as complete.
"In my experience with Clovis submittals, that $350/sqft figure and even the 8-week timeline are really state-level estimates rather than local truth, so I'd get two or three actual contractor quotes and call the Clovis Building Division directly before penciling in a budget or start date. What the data also doesn't show is that an 8-week plan check assumes a clean, complete drawing set — in my 11 years I've seen incomplete submittals push that timeline out by a month or more. — Charlotte Pemberton, Senior ADU Design Consultant"

Property Eligibility
Is My Clovis, CA Property Eligible for an ADU?
Clovis homeowners benefit from California's state ADU law — one of the most permissive frameworks in the country since 2020. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Clovis under California state law. No owner-occupancy requirement in Clovis — you can rent both units as investment properties. Ministerial permit approval — no neighbor input or discretionary design review.
Multi-Family Property
Up to 2 detached ADUs plus JADUs (Junior ADUs) within the existing main structure are permitted under California state law. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 16% of Clovis homes are in an HOA. California law (AB 670) prohibits HOAs from banning ADUs outright, but they can impose reasonable architectural standards. Our drawings include HOA submission formatting.
Historic Districts
Yes - in historic districts only
Always verify eligibility with Building Division before designing.

Clovis ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Clovis construction costs, median rental rates, and property value uplift data. Adjust the inputs to model your specific project.
Your Project
Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 27% uplift (California ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.

We turn your backyard into a rental unit. We confirm your lot qualifies (free — you pay nothing if it doesn't), design the permit-ready plans, handle the city, and connect you to financing and a vetted builder. $6,000 flat — about what an architect charges just to start. Yours would rent around $1,365/mo.
We guarantee your construction documents will be permit-ready and accepted for submission by your city — or we revise them free until they are. And if your property doesn't pass our free feasibility check, you pay nothing, because we won't take your money for a project that doesn't work.
We won't even take your money unless your property qualifies.
