Frequently Asked Questions
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.
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 American Canyon report we prepare.
Standard turnaround is 24–48 hours from when we receive complete plans. Same-day rush service is available for an additional $95 on orders placed before 10am on business days.
