Title 24 Requirements in Sonoma County
Title 24 requirements apply to many Sonoma County projects involving new conditioned space or changes to a building’s energy features. Depending on the project, this may include new homes, ADUs, garage conversions, room additions, remodels, HVAC replacements, water-heating systems, insulation, windows and doors.
For projects requiring energy documentation, a permit-ready CF1R report is generally submitted with the building plans to demonstrate compliance with California’s Building Energy Efficiency Standards. The exact forms and calculations depend on the project scope, equipment and building design.
Apex Compliance Solutions reviews your plans, completes the required energy calculations and prepares the applicable Title 24 documentation for submission to the local building department.
