Examples include workshops, storage sheds, detached private garages, tool/garden sheds, playhouses and animal shelters. Zoning Requirements The County has a zoning code that divides the unincorporated areas of the county into "specific districts." In an attempt to maintain the design and character of your neighborhood, the code imposes certain minimum design standards, setbacks and regulations about allowable uses. When you apply for a building permit, the application will automatically be routed to the Planning Division for review. Please contact the Planning Division before you finalize your plans to make sure that the accessory building meets minimum zoning requirements and does not encroach on easements or required side, front, or rear yard areas. Building Permit Fees Fees are charged for each type of permit issued such as building, plumbing, electrical and mechanical. The permit fee is based on the valuation of the project, and calculated from fee tables established in the code. The fees provide for the checking of plans and adequate field inspection of the materials and methods of construction. Environmental Health Before the plans can be finalized, confirmation by Environmental Health is required to ensure that the accessory building does not encroach upon the existing sewage system or designated reserve area. If the plot plan lacks adequate detail and the septic system location cannot be verified through file review, a field inspection may be required and a fee charged.
