Every ADU Type, One Flat Fee
🏠 Detached ADU
New standalone structure. Follows new construction compliance — all-electric, heat pump water heating, full envelope per 2025 Energy Code. CF1R registered in CHEERS.
🔗 Attached ADU
Addition connected to the primary home. Follows the alteration compliance path, scoped to the new square footage being added.
🚗 Garage Conversion
Converting an existing garage into living space. We determine the right compliance pathway based on what systems are being added or changed.
🛌 Junior ADU (JADU)
Carved out of the existing home’s footprint. Narrower compliance scope since it shares the primary residence’s envelope and systems.
📋 Additions & Alterations
Remodels affecting insulation, windows, or HVAC. We scope the report correctly and confirm compliance before you submit for permits.
🏠 Space Conversions
Basement, attic, or unconditioned space converted to living area. Compliance varies by what’s shared with the main structure — we’ll confirm the scope.
Why ADU Compliance Is Different
A lot of Title 24 providers treat all ADUs the same. They shouldn’t. The compliance path varies significantly depending on whether the ADU is new construction or an alteration, detached or attached, and what mechanical systems it shares with the main home.
Getting this wrong means your report gets flagged at the building department. We scope every ADU project correctly before running calculations.

✓ 2025 Energy Code applied (increased efficiency standards across the board)

ADU Title 24 — Common Questions
Does every ADU require a Title 24 report?
Yes. In California, a Title 24 CF1R energy compliance report is required for building permits on all ADU types — detached, attached, garage conversion, and JADU. The scope of the report varies by project type.
What documents do I need to submit?
Floor plan with dimensions, site plan showing orientation (north arrow), window schedule (sizes and locations), and wall/roof assembly details. If you have a full plan set, that works too. We review everything before starting.
Does a JADU need the same report as a detached ADU?
No. A JADU (Junior ADU) carved out of existing conditioned space typically has a narrower compliance scope since it shares the primary residence’s envelope and mechanical systems. We confirm the exact scope for every project.
Do garage conversions require all-electric systems?
It depends on what’s being added. If the conversion adds new HVAC or water heating, the 2025 Energy Code may require all-electric equipment. We review your plans and confirm what applies before generating the report.
