Title 24 Reports for Darwin Permits
Darwin sits in Inyo County, where building activity ranges from small residential remodels to ground-up new construction.
As part of Climate Zone 14 (Mountain / High Desert), Darwin projects are modeled against significant seasonal swings between hot summer days and freezing winter nights — which is why a report written for a different zone won't transfer directly.
All of our Darwin Title 24 reports are formatted for direct submittal to your local building department, whether through an online permit portal or in-person plan check. Contact us to confirm the exact department name and submittal process for your specific project address.

Climate Zone 14 — What It Means for Your Darwin Project
Climate Zone 14 is characterized by significant seasonal swings between hot summer days and freezing winter nights. Title 24 compliance software accounts for these conditions automatically, setting the specific insulation, window, and HVAC efficiency targets your Darwin project needs to meet.
Climate zone shown is an estimate based on Darwin's proximity to the nearest California Energy Commission reference station. We confirm the exact zone for your project's specific address before preparing your report — or check it yourself using the CEC's official lookup tool.
