Short answer: California Climate Zone 16 covers the mountains. The California Energy Commission assigns 228 ZIP codes to it, across 211 places including South Lake Tahoe, Truckee, Bishop, San Bernardino and Santa Clarita. Use the table below or the ZIP code lookup to confirm a project's zone.
Title 24 climate zones are assigned by the California Energy Commission (CEC) by ZIP code, not by city limits. That is why a large city can appear in more than one zone, and why 5 of the places below also have ZIP codes in another zone.

Why the Exact Zone Matters for Your Report
Title 24 is one statewide energy code, but the energy budget your design is compared against is calibrated to the climate zone, and several prescriptive requirements change by zone. If your ZIP code is split between zones, we confirm the zone from the project address before modeling. See Climate Zone 16 Title 24 requirements and how Title 24 calculations work.
Find Your Zone
Browse our city Title 24 pages for local information, or send your project address and we'll confirm the climate zone and prepare your report. See also: how climate zones affect a Title 24 report and the Climate Zone 16 overview.
