Frequently Asked Questions (FAQ)

I reside in North San Gabriel under the County unincorporate area. The property's lot size is about 55ft x 150ft. It's a one-story house. I would like to tear it down completely, and build a two-story with about 2500 sq ft. Please advice the contact information and the proper procedures on how to acquire the construction approval from the County.
