Research a Property
Before you apply for a permit, find out which County codes apply to your project and location. Start by checking permit jurisdiction*, then check zone, water sources, gopher soils and more (see checklist). Use the County's free online resources below, or hire experts.  Knowing where to site a project to minimize regulated environmental impacts could save you time and money.  Also, you'll want to know which professional reports, plans or drawings might be required.
