San Bernardino anchors its namesake county in the Inland Empire, with active residential and ADU development.
San Bernardino is in Climate Zone 10 in the heart of the Inland Empire. The zone’s extreme summer heat makes HVAC efficiency and insulation critical in every Title 24 energy report.
San Bernardino permits are reviewed by the City of San Bernardino Community and Economic Development Department. We format reports for local submission.
We prepare Title 24 reports for all project types in San Bernardino:
- New single-family home construction
- Room additions of any size
- ADUs and Junior ADUs including garage conversions
- Remodels and alterations affecting insulation, windows, or mechanical systems
- Multifamily duplexes, triplexes, and fourplexes
- HVAC replacement projects
- Window replacement projects
We also serve all surrounding San Bernardino County communities and cities throughout California.
Title 24 Projects in San Bernardino
San Bernardino's housing is mostly older than the newer Inland Empire suburbs around it. Central neighborhoods have early and mid twentieth-century homes, postwar tracts fill much of the city, and the northern neighborhoods climb toward the foothills of the San Bernardino Mountains. Many lots are large enough for a second unit, which makes ADUs and garage conversions a practical way to add housing on existing property.
Older houses bring predictable Title 24 challenges in a hot inland climate: wall and floor insulation that is thin or missing, single-pane windows, evaporative coolers or aging package units, and ducts in unconditioned attics. When an addition is modeled along with the existing house, or when equipment is replaced, those conditions influence what is needed to comply. Replacing old cooling equipment with a heat pump is one of the most frequent projects, and our HVAC replacement Title 24 page explains what that involves. For backyard units, see ADU Title 24 reports.
Homes in the foothill areas may also fall under wildfire-area construction rules in Chapter 7A of the California Building Code, which are separate from the energy report.
