Construction of a storm shelter requires an accessory structure permit. Electrical or plumbing construction work in conjunction with storm shelter construction requires separate permit(s).
A storm shelter is defined as an enclosed accessory structure designed to protect occupants from violent weather events. A maximum of two accessory structures are allowed per lot or property.
Storm shelters may be placed in the garage or above ground or underground in the side or rear yard. If located in a side yard, a storm shelter shall not extend closer to the front property line than the front of the house. A storm shelter must be set back 6 feet from side and rear property lines. For corner lots, a storm shelter must be set back 15 feet from the side yard lot line adjacent to a street.
For underground storm shelters installed in existing garage concrete foundations, an engineered foundation plan must be provided.
