Permits in Larkspur are processed through Larkspur Building Department. We prepare reports formatted to match their submittal requirements, whether that's an online portal or in-person review.

What is a Title 24 Energy Report?
+

It's prepared using state-approved software and is required for most building permits involving conditioned space.
