How long does a Title 24 Report take?

For a typical ADU, a registered Title 24 report (the CF1R) is prepared and registered within a few business days, and because we produce it alongside your MEP plans, it is ready on the same schedule as your MEP set — the standard 5-business-day turnaround — rather than adding a separate wait. Faster turnaround is available when your permit timeline is tight.

What drives the timeline

• Project type. A garage conversion under alteration rules is generally simpler than a new detached ADU carrying full envelope, HVAC, water-heating, and potential solar requirements.
• Compliance path. A straightforward prescriptive design moves quickly; a performance-path model balancing trade-offs across the whole building takes more analysis.
• Information readiness. The biggest variable is having a finalized floor plan and a confirmed project address — the address sets your climate zone (one of 16) and the applicable code cycle, and changes to the layout after the report is built require it to be reworked.
• Registration. The CF1R must be registered with an approved data registry before submittal; an unregistered printout is frequently rejected at intake, so registration is part of the delivery, not an afterthought.

Turnaround options

These turnaround tiers apply to the whole coordinated package, so choosing Priority or Express moves both your MEP plans and the Title 24 report onto the faster schedule together.

Where it fits your permit timeline

1. Finalize the ADU floor plan and confirm the project address (this fixes the climate zone and code cycle).
2. We prepare the CF1R and the coordinated MEP plans together so equipment efficiencies match.
3. You submit the registered CF1R with the full permit package.
4. During construction, contractors complete the CF2R, and a HERS rater completes the CF3R where required.

How to keep your schedule on track

The fastest projects share a few habits. Lock the floor plan before the report is started — late layout changes are the most common cause of rework, because moving a wall, a window, or the water heater can change the energy model. Confirm the project address up front so the climate zone and code cycle are correct from the start. And decide your service level early: if your permit window is tight, Priority or Express moves the whole package, not just one piece.

Preparing the report with the MEP plans is what keeps the timeline tight — there's no second vendor to wait on, and the energy report and construction sheets are consistent from day one.

Keep in mind that the report's turnaround is separate from your city's review timeline — once submitted, plan check takes additional time, and some jurisdictions have extra intake steps. The applicable code cycle and local amendments vary — confirm with your local building department.
