Client, address and contractor details are intentionally omitted.
Project Overview
This anonymized case study describes one residential garage conversion in the Los Angeles area, completed in September 2026. Converting a garage to conditioned living space typically requires energy compliance documentation with the permit application. The client, contractor, street address and other identifying details are not published.
Information Reviewed
Apex reviewed dimensioned plans and project information covering:
- The building envelope
- Doors and windows
- HVAC
- Water heating
The plans and project files are private and are not reproduced here.
Compliance Process
Applicable residential compliance modeling was completed with CBECC-Res, the state-approved compliance software used for residential Title 24 projects. The compliance documentation followed the applicable CHEERS registration workflow. For a general description of how Apex approaches every report, see How Apex Prepares a Title 24 Report.
Deliverables
The completed energy compliance package was delivered for permit submittal. This page describes the documentation work only; it does not report a permit decision, an inspection result or a project turnaround time.
HERS and Field Verification
Apex prepares compliance documentation; it does not perform HERS field verification or inspections. When a project's design relies on measures that require field verification, that testing is performed by an independent certified HERS rater and documented on a CF3R. Apex can coordinate with or refer a project to a rater — see HERS Rater Coordination — and the rater's fees are billed separately. For how the CF1R, CF2R and CF3R fit together, read What Is a CF1R Report?.
What Similar Projects Should Prepare
For a garage conversion, having the following ready helps a report move without back-and-forth:
- The project address and the city issuing the permit
- Dimensioned plans of the converted area
- Building-envelope details, including insulation values
- Window and door information
- Proposed heating, cooling and water-heating equipment
Standard turnaround is 3–5 business days after complete project information and plans are received. Garage conversion reports start at $250 — see pricing. Learn more about garage conversion Title 24 reports and CF1R reports, or request a quote.
