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 Questions

How much does it cost to build an ADU in Clovis? +

What is the maximum ADU size allowed in Clovis? +
Clovis permits ADUs up to 1,200 sq ft. The maximum height is 16 ft. Side setbacks are 4 ft and rear setbacks are 4 ft. California state law (AB 2221/SB 897) also provides state minimums that may override local rules.

Do I need owner-occupancy to build an ADU in Clovis? +
No — Clovis does not require owner-occupancy for ADUs. You can rent both the main house and the ADU as investment properties.
What's the rental income potential for an ADU in Clovis? +
In Clovis, a 1-bedroom ADU rents for approximately $1,365/month. Studios average $1,195 and 2-bedroom units bring $1,655. With an occupancy rate of 95%, annual gross rent on a 1BR ADU would be approximately $15,561.
How much does it cost to get ADU drawings in Clovis? +

What drawings are included in the permit set? +
Our Standard package includes everything Clovis's building department requires: site plan, floor plans, elevations (all four sides), electrical plan, and energy compliance (Title 24). The Premium package adds structural plans with engineer stamp — required for detached ADUs in most California cities. All drawings are CA-code compliant and formatted for local submission.
Can I convert my garage to an ADU in Clovis? +
Yes. Garage conversions are one of the most cost-effective ADU options in Clovis. Conversion costs start around $145,000 — significantly less than new construction. The existing footprint counts toward ADU square footage limits. Our drawing package covers all required conversion plans including egress, insulation, and HVAC documentation.
What neighborhoods in Clovis are best for ADU investment? +
Old Town Clovis, Tarpey Village, Sierra Bicentennial Park area. Older single-family lots near downtown with strong rental demand and walkable amenities, ideal for ADUs.
Is Clovis ADU-friendly? +
Clovis is governed by California state ADU law, one of the most permissive in the country. Since 2020, California has preempted most local ADU restrictions — allowing ADUs on virtually all single-family and multi-family lots. Clovis allows ADUs up to 1,200 sq ft. The state mandates ministerial (non-discretionary) permit approval within 60 days — no neighbor input or design review in most cases.
How much will an ADU increase my property value in Clovis? +
ADUs in Clovis typically increase property values by 27%. On a $390,000 home, that's an estimated $105,300 in added value. Cap rates average 6.8% in Clovis.
Can I use my Clovis ADU as a short-term rental (Airbnb / VRBO)? +
Clovis restricts short-term rentals (under 30 days) in ADUs. The unit can be rented long-term — a 12-month lease is the most straightforward path. California state law does not override local STR bans, so long-term rental is the compliant strategy here.
Does Clovis's seismic zone affect ADU construction requirements? +
Clovis falls within Seismic Design Category Seismic Design Category D (ASCE 7/IBC) for typical sites in Clovis/Fresno area. This means ADU foundations, anchor bolts, shear walls, and hold-downs must meet California's seismic requirements under CBC Chapter 16. Our Premium package includes stamped structural drawings engineered for Clovis's seismic zone — required for detached ADUs and strongly recommended for garage conversions where the existing structure may not meet current seismic standards.
Where do I submit ADU plans in Clovis? +
Building Division handles ADU permit applications — online submission is available through the permit portal. Permit fees in Clovis range from $3,500 to $12,000 depending on project scope and valuation. Plan check typically takes 8 weeks. Our drawing sets are formatted specifically for Clovis's submittal requirements to minimize plan check cycles.
