Title 24 compliance in Hillsborough, California

All new residential and commercial construction in Hillsborough must comply with Title 24, the California Building Energy Efficiency Standards. That covers HERS verification for new homes and major renovations, ECC verification for applicable projects, and acceptance testing for mechanical systems.

Title 24 raters in Hillsborough are certified professionals who perform field inspections to verify that a building’s energy systems, including HVAC, insulation, windows and lighting, meet California’s requirements. Without a certified rater’s sign-off, a building permit cannot be finalised.

Whether you’re a contractor, builder or homeowner, lining up a qualified local rater early saves time and avoids the kind of delay that only shows up the week your inspection is scheduled.
