Title 24 Compliance in Contra Costa County

Contra Costa County is anchored by Martinez and includes communities across 2 distinct California energy climate zones. Every conditioned-space building permit issued within the county — whether through an incorporated city's building department or the county's own permitting office for unincorporated areas — requires a signed Title 24 Energy Compliance Report.

Mixed Marine conditions, characterized by coastal fog and moderate summers with cooling-dominant afternoons, shape the specific insulation, glazing, and HVAC efficiency targets used in every report we prepare for Contra Costa County projects.

Frequently Asked Questions

Can I use a Title 24 report from another consultant if I just need it updated?
+

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.

What format will my report be delivered in?
+

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.

What happens if my plans change after I receive my report?
+

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.

What information do you need to prepare my 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.

What is a Title 24 Energy Report?
+

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.
