This information is the most common for how to obtain the necessary approval for your project and is not representative of all the conditions you may encounter.
WHO SHOULD APPLY?
Property owners may obtain permits in their own name, however, it is strongly recommended a properly licensed contractor pull the permits as the responsible party so the county can better assist in gaining compliance for defective work.
