Accessory Structure Permit

An Accessory Structure permit is required for construction of any improvements that serve a primary use located on the same piece of land as a main structure, but is intended for secondary use. For example, a house may have a detached garage or storage shed as accessory structures. Other examples of accessory structures include gazebos, generators, picnic pavilions, boathouses, storage sheds, and similar buildings. Accessory Structure permits are generally issued on the same day as application following review by a permit analyst. However, if the department determines that complete plans are required for your job, the plans are sent through a plan review process, which involves reviews to verify compliance with the  City's amendments to the International Building Code and the City’s zoning ordinance. You can look up your zoning here. Depending on the specifics of your project, this review may also include or require approvals from other entities (Historic Districts Landmark Commission, Vieux Carré Commission, City Planning Commission, etc.). A building permit will only be issued after the plan review process is completed and compliance with all applicable regulations is verified.


Same day in some situations, when review is required: Residential projects, 2-5 days; Commercial projects, 20-30 days.
