Title 24 HERS, Permits & Final Inspections in Santa Ana
CHEERS-certified HERS / ECC Rating, mechanical/electrical/plumbing permit expediting, and final inspections in Santa Ana. Same-day field results. We work with the City of Santa Ana Building & Safety division weekly - from downtown's 92701 core to Floral Park's historic streets to the 92705 foothills shared with unincorporated North Tustin.
Santa Ana is one of our highest-volume Orange County cities.
Santa Ana is ERE's #8 city by permit volume - roughly 2.2% of every permit we've pulled. The work is split across very different neighborhoods: dense downtown blocks in 92701, the central historic district around Floral Park (92706), and the eastern foothills in 92705 that share a ZIP with unincorporated North Tustin and Lemon Heights. Add south Santa Ana (92707) and southwest (92704), and we're on the 5, 22, and 55 weekly. Santa Ana sits on our daily Orange County route alongside Tustin, Orange, and Garden Grove.
Working with the City of Santa Ana Building & Safety
- Department: City of Santa Ana Building & Safety
- Address: 20 Civic Center Plaza, Santa Ana, CA 92701
- Phone: (714) 647-5800
- Submission methods: Online Portal, In-Person Counter
- Counter hours (typical): Monday to Thursday 8:00 AM to 3:00 PM, Wednesday 8:00 AM to 2:00 PM (shorter on Wed), alternating Fridays 8:00 AM to 3:00 PM. Santa Ana keeps a tighter counter window than most OC cities - always confirm current hours on the city's portal before showing up.
We pull mechanical, electrical, and plumbing permits, run plan-check correction cycles, and coordinate the final inspection with the city inspector and the homeowner. Santa Ana takes online submittals for most MEP work, with the counter as the backup for projects that need a person in the room. For 92705 addresses outside city limits we coordinate with OC Development Services instead.
What we do in Santa Ana
- Title 24 HERS / ECC Rating testing - duct leakage, refrigerant charge, cooling coil airflow, fan efficacy. CF1R / CF2R / CF3R prepared and registered with CHEERS, at no additional charge.
- Permit expediting - mechanical, electrical, plumbing. Online portal or counter, whichever the city wants for the scope. Plan-check corrections handled.
- Final inspections & closeout - we set up the final with the City of Santa Ana 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 - what it means for your test
Santa Ana sits in California Climate Zone 8 - the inland Orange County zone. The exact zone is set by the California Energy Commission and depends on the project address. Climate zone affects which Title 24 prescriptive paths apply and which HERS / ECC measures your project needs to verify. CZ 8 has slightly stricter cooling-side requirements than the coastal CZ 6 you'll find a few miles west in Costa Mesa or Huntington Beach, so duct leakage and refrigerant charge verification carry extra weight here. We confirm the zone for your specific address before quoting.
Frequently asked - Santa Ana
When does Title 24 require HERS / ECC testing for a Santa Ana project?
For most permitted work that touches energy systems, yes. HVAC alterations - replacing a coil, condenser, furnace, or more than 40 feet of ducting - typically require duct leakage testing and refrigerant charge verification. New construction and ADUs almost always require multiple HERS measures. Window replacements, insulation upgrades, and water-heater swaps may trigger HERS depending on scope and your climate zone. Santa Ana Building & Safety plan check will tell you what's required when they review your permit; we can also confirm before you submit.
Do you also work in cities adjacent to Santa Ana, and what about 92705?
Yes. Tustin, Orange, Garden Grove, Fountain Valley, Costa Mesa, Westminster, and Irvine are all part of our regular Orange County coverage - separate building departments, but we know each one. The 92705 ZIP is shared between Santa Ana proper and unincorporated Orange County (North Tustin, Lemon Heights, Cowan Heights edges). If your project address falls in unincorporated 92705, the jurisdiction is OC Development Services rather than the City of Santa Ana - we handle both. Tell us the street address when you request a quote and we'll confirm which jurisdiction you're in.
What's the typical permit-to-closeout timeline in Santa Ana?
For a standard MEP permit (HVAC change-out, electrical service upgrade, water heater swap), figure roughly 1 to 2 weeks from submittal to permit issuance via Santa Ana's online portal - often faster on simple scopes. The HERS / ECC test happens once installation is done, with same-day field results. Final inspection scheduling adds another 2 to 10 business days depending on inspector availability. Most simple projects close out within 4 to 6 weeks total. ADUs and additions take longer because of plan check. Santa Ana counter hours are shorter than most Orange County cities, so we plan around that.
How fast can ERE finish a HERS test in Santa Ana?
Same-day field results in your inbox the day of the test, and CF3R registered with CHEERS. Booking lead time is typically less than a week - Santa Ana is on our daily Orange County route and we can usually slot in a test within 2 to 5 business days.
