Can I Build Fence in Fresno, CA? (2026)

Can I build an ADU on my Fresno property?

Yes. California state law requires Fresno to permit ADUs by-right on all residential lots. You can build a detached ADU up to 1,200 sqft or a Junior ADU (JADU) up to 500 sqft within your existing home. Fresno's Central Valley location means construction costs are often $80,000–$150,000 for a detached ADU — significantly less than Bay Area or LA. Apply through Fresno DARM at (559) 621-8000 or visit 2600 Fresno Street.

How does Fresno's extreme heat affect ADU construction requirements?

Fresno's Climate Zone 13 (San Joaquin Valley hot interior) is one of California's most demanding for energy compliance. Title 24 Part 6 requires enhanced insulation (ceiling R-38+, wall R-15+), low-SHGC windows to reduce solar heat gain, and high-efficiency HVAC systems. Cool roofs (minimum SRI 75 for steep slope) are required for new construction. Budget for these code-required upgrades in your ADU project — a well-insulated ADU in Fresno can reduce cooling costs by 30-40% compared to a minimally-insulated structure.

Does Fresno's air quality affect when I can do outdoor construction?

Yes. Fresno is in the San Joaquin Valley Air Pollution Control District (SJVAPCD) which regularly issues Spare the Air days and construction activity restrictions during high-pollution periods (typically summer ozone season and winter particulate matter season). Some grading and demolition activities require SJVAPCD permits or notification. Contractors working in Fresno must be aware of SJVAPCD Rule 9410 (Employer-Based Trip Reduction) and Rule 4102 (nuisance dust) during construction.

Is solar worth it in Fresno compared to coastal California?

Solar is often more economically compelling in Fresno than coastal California. Fresno receives approximately 290 sunny days per year with high solar irradiance (low coastal fog), so panels generate more power per installed watt. PG&E NEM 3.0 applies — export rates are reduced but self-consumption value is high given Fresno's large summer cooling loads. Fresno homes typically use 30-50% more electricity annually than Bay Area homes due to air conditioning, making solar payback periods shorter.

Can I sell food from my home kitchen in Fresno?

Yes, under California's Cottage Food Law (AB 1616). You can produce and sell non-potentially-hazardous homemade foods (baked goods, jams, candy, dried foods) without a commercial kitchen license. Class A permits allow direct sales with no revenue cap; Class B allows retail sales up to $75,000/year. Register with Fresno County Department of Public Health. Fresno has active farmers markets (Tower District, Vineyard Market, Fulton) where cottage food vendors can sell directly to customers.

Are there any Fresno flood zones I should know about before buying property?

Fresno has flood risk zones primarily near the San Joaquin River in the northwest, and along Dry Creek, Fresno Slough, and various drainage channels throughout the city. Use FEMA's Flood Map Service Center (msc.fema.gov) to check your specific parcel. The Fresno Metropolitan Flood Control District (FMFCD) manages over 260 miles of drainage channels in the Fresno-Clovis area. Properties in FEMA Special Flood Hazard Areas (SFHA) require flood insurance with federally-backed mortgages and elevation certification for new construction.

What is a JADU and how does it differ from a regular ADU in Fresno?

A Junior ADU (JADU) is a California-specific designation under Gov Code §66333 (Stats. 2024 Ch. 7 §20) allowing a small secondary unit of up to 500 sqft within the existing footprint of your single-family home or attached garage — no new structure required. A standard ADU can be a new detached structure up to 1,200 sqft, or a larger attached addition. JADUs are typically faster and cheaper to create since no new foundation or exterior shell is needed. JADUs can share a bathroom with the main home but must have an efficiency kitchen. On a single-family lot in Fresno, you can have one ADU AND one JADU simultaneously.
