We prepare every report using current state-approved compliance software, tailored to your project's specific climate zone and building department requirements.
Whether your project is in a major metro area or a small unincorporated community, the same statewide compliance standard applies — and our reports are formatted to meet the submittal requirements of building departments across all 58 California counties.

Standard turnaround is 3–5 business days after complete project information and plans are received. Rush service may be available depending on project scope.
We offer affordable Title 24 revisions whenever plans change before or after permit submittal. Send us the updated plans and a description of what changed, and we'll reissue a corrected report quickly.
In most cases, yes — we can review an existing report and prepare a revision rather than starting from scratch, which is typically faster and less expensive than a brand-new report.
At minimum we need the site address, a dimensioned floor plan, window schedule, proposed HVAC and water heating equipment, and insulation values. The more complete your plans, the faster we can turn around your report.
Your completed report is delivered as a signed PDF, formatted for direct upload to online permit portals or printing for in-person submittal — whichever your building department requires.
