Oakland is a major Bay Area city with dense residential, ADU, and multifamily development.
Oakland sits in Climate Zone 3 — one of California's mildest zones with cool marine influence year-round. Title 24 requirements here emphasize heating efficiency more than cooling, with solar PV and heat pump requirements still applying under the 2025 code.
Oakland projects go through the City of Oakland Planning and Building Department. We format every report for Oakland submission.
We prepare Title 24 reports for all project types in Oakland:
- 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 Berkeley, Fremont, Hayward, San Leandro, and all of the East Bay.
Title 24 Projects in Oakland
Oakland has one of the oldest housing stocks in the Bay Area. Victorians, Craftsman bungalows and early twentieth-century homes fill the flatland neighborhoods, many of them converted to or built as two- to four-unit buildings, while the Oakland Hills hold mid-century and newer homes on steep lots. That history makes remodels, basement and attic conversions, ADUs and small multifamily projects far more common than ground-up tract construction.
Older Oakland houses often have uninsulated walls, raised floors over a crawlspace, original single-pane windows and a gas furnace with ducts under the house. In a heating-focused climate like this one, those conditions carry weight when an addition or conversion is modeled together with the existing building. Replacing a furnace with a heat pump, or converting an unfinished basement into living space, are typical triggers. Our HVAC replacement Title 24 and ADU Title 24 report pages explain what we need.
Hillside lots may also fall under wildfire-area construction rules. Those come from Chapter 7A of the California Building Code, not the energy code, and are reviewed separately from your Title 24 report.
