Frequently Asked Questions
A Title 24 Energy Report is a California-mandated compliance document that demonstrates a building project meets the energy efficiency standards in Title 24, Part 6 of the California Code of Regulations. It's prepared using state-approved software and is required for most building permits involving conditioned space.
ADU and garage conversion projects make up a large share of the Title 24 reports we prepare for El Portal, followed by room additions and HVAC/window remodels.
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 El Portal report we prepare.
