Fresno is the largest Central Valley city, where hot summers make cooling and insulation central to Title 24 compliance.
Fresno sits in Climate Zone 13 — one of California's most thermally demanding zones. Long hot summers regularly exceeding 100°F and cool Central Valley winters mean your Title 24 report must account for high-performance ceiling and wall insulation, high-efficiency HVAC, and carefully specified window U-factor and SHGC values. We model every Fresno project using CEC-approved software calibrated to Climate Zone 13.
Title 24 reports for Fresno city projects are submitted to the City of Fresno Development and Resource Management Department. Fresno County projects go through Fresno County. We serve both and format every report for the correct local jurisdiction.
We prepare Title 24 reports for all project types in Fresno:
- 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 Clovis, Madera, Visalia, Tulare, and all of the Central Valley.
Title 24 Projects in Fresno
Fresno's housing ranges from early twentieth-century bungalows in central neighborhoods such as the Tower District to newer subdivisions toward the north and the outer edges of the city. Rural residential parcels in unincorporated Fresno County add custom homes and larger outbuildings converted to living space.
In older central Fresno homes, the typical projects are room additions, ADUs behind existing houses and replacement of aging air conditioners and furnaces. These homes often have ducts in the attic and limited insulation, and when an addition is modeled together with the existing house, those conditions matter. In newer neighborhoods, work more often means a detached ADU, a JADU, or a switch to a heat pump. New single-family homes need a full performance model, including solar PV where it applies.
Because it is a cooling-dominated climate, small plan details carry weight here: the orientation of large windows, overhangs, the duct location and the cooling equipment efficiency. Listing them clearly on your plans avoids delays. The Title 24 requirements page walks through each area of the building.
