Accessory buildings are  secondary structures placed on residential properties. Depending on your zoning designation and property layout, you may be permitted to construct an accessory building on your property. All accessory buildings, even if they do not require a concrete foundation, are required to be permitted.

You can read the full guidelines for accessory buildings here.

— City Code of Ordinances

General Guidelines

Accessory buildings may not be placed in an easement or in a way that negatively impacts drainage. Depending on your zoning you can have one or two buildings; and in some zoning districts no accessory buildings are allowed.

What needs to be submitted:  

  1. Residential Building Permit Application
  2. A Site Plan - must show location of home, proposed location of building, and, if it applies, the location of septic spray heads and tank
  3. Description or picture of the building
  4. All contractor(s) must be registered (General contractor, electrician, air conditioning, and plumbing)
  5. Payment must also be received at time of submission

A single-family property may have an accessory building up to 1,000 square feet in size. Type A units (less than 160 square feet) can be on skids but anchored to withstand 90 mph winds.  Type B units and/or Type C units (greater than 160 sq. ft.) MUST be on a concrete slab with beams on all four corners as described in the City's Code of Ordinances.
