Anaheim is Orange County’s largest city by population and runs one of the busiest building permit programs in Southern California. The Anaheim Building Division at 200 S. Anaheim Blvd. requires a Title 24 energy compliance report (CF1R) for most permit types. The Building Division confirmed the 2025 California Building Standards Code is in effect for all projects submitted on or after January 1, 2026. Furthermore, Anaheim has adopted the 2025 code with local amendments for residential and non-residential construction.
Anaheim’s permit market spans a unique mix of uses. The Resort District, major hotel and hospitality permits are common. In west and south Anaheim, residential ADU and new construction permits are high volume. In the Canyon Industrial Area, commercial warehouse and manufacturing permits are active. Each project type has its own Title 24 requirements and forms.

Anaheim Title 24 Climate Zone 8
Anaheim is in California Title 24 Climate Zone 8. Zone 8 covers inland Orange County and differs meaningfully from the coastal Zone 6 cities like Huntington Beach and Newport Beach. Because of its inland location, Anaheim experiences hotter summers and higher cooling loads. In turn, Zone 8 requires more from HVAC systems, insulation, and windows than Zone 6.
In practical terms, a new home in Anaheim needs higher ceiling insulation and a larger solar PV system than a comparable home in coastal Orange County. Additionally, the Zone 8 HVAC sizing formula accounts for the higher peak cooling loads. For this reason, coordinating your mechanical and window selections with the Title 24 energy model early in design saves time and avoids plan check corrections.
Zone 8 compliance requirements for Anaheim projects:
Ceiling insulation minimum R-38 | Wall insulation R-15 or R-13+4ci | Window U-factor ≤ 0.30 | Window SHGC ≤ 0.23 | Solar PV sized to Zone 8 capacity factor | Heat pump baseline for space and water heating. We confirm your exact zone by project address before starting any report. The California Energy Commission climate zone tool provides the official zone map. See also our full California Title 24 climate zones guide.

CF1R Reports and HERS Testing in Anaheim
Anaheim’s Building 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 current to the 2025 code. The CF1R must be registered with an approved HERS provider before plan check submittal at the Anaheim Building Division counter.
| CF1RCertificate of Compliance — submitted with the Anaheim Building Division permit application | CF2RCertificate of Installation — signed by the installing contractor in the field | CF3RCertificate of Verification — signed by a HERS Rater before Anaheim final inspection |
HERS Testing in Anaheim
A certified HERS Rater must verify specific energy systems in Anaheim homes before the certificate of occupancy is issued. Common HERS measures in Anaheim Zone 8 projects include duct leakage testing, heat pump refrigerant charge verification, and mechanical ventilation flow rate testing. Your CF1R identifies exactly which measures apply to your project.
Title 24 Services for Anaheim Projects
New Home Construction in Anaheim
New single-family homes in Anaheim 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 sized to the Zone 8 formula and battery readiness wiring also apply. We prepare the complete CF1R package formatted for Anaheim Building Division submittal. See our residential new construction service page for full details.
Title 24 ADU, Granny Flat, and In-Law Unit Reports in Anaheim
Anaheim has strong ADU permit activity across its residential neighborhoods. 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 — new construction or alteration — changes based on how Anaheim classifies your specific project. We confirm the right approach before starting your report. See our Title 24 ADU service page for more information.
ADU exception for small Anaheim units: ADUs under 500 sq ft may qualify for a water heating compliance exception under the 2025 code. An electric tankless heater may qualify instead of a heat pump water heater. We confirm eligibility when you submit your plans.
Room Additions in Anaheim
A room addition in Anaheim that adds conditioned floor area triggers Title 24 compliance. Under the 2025 code, all new walls, ceilings, and windows must meet Zone 8 insulation and fenestration values. Any new HVAC or ducts in the scope must also meet the 2025 efficiency and leakage standards. See our room addition service page and alteration service page for details.
Remodels and Alterations in Anaheim
Not every Anaheim remodel triggers a Title 24 report. However, many do. Common triggers include HVAC replacement, window replacement, water heater replacement, and significant lighting changes. If you are unsure whether your Anaheim project needs a report, submit your project details and we will confirm before you pay.
