Why Climate Zone 3 Matters Here

Half Moon Bay's designation as Climate Zone 3 reflects mild, marine-influenced conditions with minimal temperature swings, a factor our energy models account for when calculating your compliance margin.

Estimated from proximity to the nearest CEC reference station — we confirm the exact zone for your project's address before preparing your report.

Frequently Asked Questions

Do you handle both prescriptive and performance compliance paths?
+

Yes. We evaluate every project against both paths and recommend whichever gets you to compliance with the least cost and complexity — sometimes prescriptive is simpler, sometimes performance modeling unlocks more design flexibility.

Do ADU projects in Half Moon Bay require HERS verification?
+

It depends on the compliance path used in your energy model. Certain prescriptive credits — duct sealing, refrigerant charge verification, air leakage testing — trigger a HERS verification requirement. We flag these clearly in every Half Moon Bay report we prepare.

Is a Title 24 report the same as a HERS rating?
+

No. The Title 24 report (CF1R) is the energy design document submitted with your permit. HERS verification is a separate field inspection process — required only for certain compliance credits — performed by a certified HERS rater during construction.
