Fresno Title 24 Climate Zone 13
Fresno is in Climate Zone 13. This is the southern San Joaquin Valley with some of the most extreme summer heat in California. Temperatures regularly exceed 100 degrees from June through September. However, unlike Zones 10 and 15, Fresno also experiences significant winter cold. Temperatures can drop below freezing from December through February. Zone 13 compliance requires attention to both peak summer cooling and winter heating loads.
Fresno's air quality challenges influence local building policies. The San Joaquin Valley has some of the worst air quality in the United States. The San Joaquin Valley Air Pollution Control District actively pushes electrification. It works to reduce gas combustion in buildings. The 2025 code's heat pump baseline aligns with these regional air quality goals. We prepare all Fresno Title 24 reports using current CEC-approved software current to the 2025 code.
We confirm your exact climate zone by project address before starting any report. The California Energy Commission climate zone tool provides the official zone map. You can also view our full California Title 24 climate zones guide for zone-by-zone details.
We also serve nearby cities: Sacramento • Stockton • Bakersfield • Visalia • Clovis • Modesto. See our Fresno County page or the full cities index for all locations we cover.
CF1R Reports and HERS Testing in Fresno
City of Fresno Development and Resource Management Department, Building and Safety Division requires a CF1R Certificate of Compliance for all residential permits that trigger Title 24. Title 24 Calcs prepares the CF1R using current CEC-approved software. The software uses the 2025 code. We register it with an approved HERS provider before delivery. As a result, it is ready for permit submittal.
| CF1RCertificate of Compliance — submitted with the Fresno permit application | CF2RCertificate of Installation — signed by the installing contractor in the field | CF3RCertificate of Verification — signed by a HERS Rater before Fresno final inspection |
HERS testing is mandatory for specific energy systems. A certified HERS Rater must verify duct leakage, heat pump refrigerant charge, ventilation flow rates, and battery readiness. This verification is required before issuing a certificate of occupancy. Your CF1R identifies all applicable HERS measures for your Fresno project.
Title 24 Services for Fresno Projects
New Home Construction in Fresno
New single-family homes in Fresno need a Title 24 new construction report for every permit submitted on or after January 1, 2026. Heat pumps are the prescriptive baseline for space and water heating. Solar PV and battery readiness provisions also apply to most new homes. We prepare the complete CF1R package. We register it and deliver it ready for permit submittal.

Title 24 ADU, Granny Flat, and In-Law Unit Reports in Fresno
Fresno's residential neighborhoods — particularly in the Tower District, Sunnyside, and older central Fresno areas — have large lots suitable for detached ADU construction. Zone 13's extreme summer heat means ADU cooling systems and insulation are especially important. A Title 24 ADU report is required for every new ADU, JADU, granny flat, or in-law unit submitted on or after January 1, 2026. The compliance path depends on how the project is classified. Title 24 Calcs confirms the correct classification before starting your report. See our ADU Title 24 service page for more information.
Room Additions and Alterations in Fresno
Room additions that add conditioned floor area trigger Title 24 compliance. All new walls must meet Zone 13 insulation values. Ceilings and windows must also meet Zone 13 fenestration requirements. Additionally, HVAC replacement, window replacement, and water heater replacement may trigger a report. See our room addition service page and alteration service page for details. If you are unsure whether your Fresno project needs a report, submit your project details and we will confirm before you pay.
Title 24 Compliance for Fresno Remodels
Common triggers for Title 24 alteration reports in Fresno include HVAC replacement and window replacement to meet Zone 13 U-factor minimums. Heat pump water heater installation and significant lighting changes also trigger reports. These scopes of work require energy compliance documentation at plan check submittal.
Commercial Title 24 Reports in Fresno
Fresno's commercial market spans agricultural processing facilities, healthcare campuses, government buildings, retail centers, and the downtown revitalization corridor. Zone 13's dual heating and cooling demands affect commercial HVAC efficiency requirements differently than coastal California zones. We prepare NRCC-ENV, NRCC-MCH, and NRCC-LTI forms for all nonresidential project types throughout Fresno. The 2025 code requires solar PV for most new nonresidential buildings. It also requires ASHRAE Guideline 36 controls for VAV systems.
