Title 24 HERS, Permits & Final Inspections in Westminster, CA
CHEERS-certified HERS / ECC Rating, mechanical / electrical / plumbing permit expediting, and final inspections in Westminster, CA. HERS (Home Energy Rating System) is the field-verification side of Title 24 — California’s Building Energy Efficiency Standards, Title 24, Part 6 of the California Code of Regulations — renamed ECC (Energy Code Compliance) by the California Energy Commission under the 2025 code. Same-day field results. We file through the city’s Westminster Build portal and run the 92683 tracts weekly — from Little Saigon’s Bolsa Avenue corridor to the neighborhoods off Beach Boulevard.
One ZIP — 92683 — covers the whole city.
Essentially every Westminster permit we handle is in 92683, the single ZIP code spanning the city. Westminster incorporated in 1957 and built out fast: most of its housing is 1950s-to-1970s single-family tracts, which keeps HVAC change-outs, duct replacements, and water-heater swaps at the top of our job list here. The city is also home to Little Saigon, the commercial corridor along Bolsa Avenue, where tenant improvements add nonresidential Title 24 scopes — NRCC documentation, the nonresidential certificates of compliance — to the residential mix. One caution: Midway City, the unincorporated pocket inside Westminster (ZIP 92655), is permitted by the County of Orange, not the city — we verify the jurisdiction before anything is filed.

What we do in Westminster
- Title 24 HERS / ECC Rating testing — duct leakage, refrigerant charge, cooling coil airflow, fan efficacy. CF1R / CF2R / CF3R — the Title 24 certificates of compliance, installation, and verification — prepared and registered with CHEERS at no additional charge.
- Permit expediting — mechanical, electrical, plumbing. Filed through Westminster Build, by email, or at the counter, whichever fits the scope. Plan-check corrections handled end to end.
- Final inspections & closeout — we schedule the final with the City of Westminster and the homeowner, confirm both are available, brief the homeowner on what the inspector will want to see, and hand off the HERS test and permit packet. When roof or attic access is needed, we drop a single-story ladder in the morning and pick it up that afternoon.
Climate Zone 8 — right at the coastal boundary
Westminster sits in California Climate Zone 8, the inland Orange County zone — but only barely. Coastal Climate Zone 6 begins one city over in Huntington Beach and Seal Beach, and the boundary matters: CZ 8’s hotter cooling-design conditions are why the prescriptive path requires refrigerant charge verification on altered air conditioners here, a measure CZ 6 doesn’t demand. The California Energy Commission assigns the zone by project address on its climate zone map, so we confirm yours before quoting. The 2025 Building Energy Efficiency Standards took effect January 1, 2026 and apply to permit applications submitted on or after that date — earlier applications stay on the 2022 code.
Frequently asked — Westminster
Is a HERS / ECC test required for my Westminster project?
If the permitted work touches an energy system, usually yes. In Climate Zone 8 that means duct leakage testing and refrigerant charge verification on most HVAC change-outs, and multiple verified measures on new construction and ADUs. Projects with permit applications dated on or after January 1, 2026 fall under the 2025 Energy Code, which extends refrigerant charge verification to heat pumps in all 16 climate zones. The required tests are listed on your project’s CF1R — send it to us and we’ll quote exactly what’s needed.
What is Westminster Build, and do I have to use it?
Westminster Build is the city’s digital permit portal — applications, plan-check status, and fees all run through it, and it’s the fastest path for standard mechanical, electrical, and plumbing permits. The Building Division also takes email and in-person submittals at City Hall. We file through Westminster Build for our clients, track the plan check, and book the city inspection once the work is done.
My address says Westminster, but City Hall can’t find my permit. Why?
You may be in Midway City — the unincorporated pocket inside Westminster’s boundaries. Midway City addresses (ZIP 92655) are permitted by the County of Orange, not the City of Westminster, so applications and inspections go through OC Development Services. We work in both jurisdictions and can tell you which one your parcel belongs to before anything gets filed.
How fast can ERE turn around a test in Westminster?
Booking lead time is typically 2 to 5 business days — Westminster sits on the west Orange County route we run weekly, alongside Garden Grove, Cypress, and Huntington Beach. Field results arrive the same day as the test, and the CF3R is registered with CHEERS at no extra charge.
