Do I need a permit for accessory dwelling unit (adu) in Lake City?
Most likely yes. Accessory dwelling unit (adu) usually requires a permit in Georgia. Confirm the specifics with Lake City.
An ADU is a dwelling unit that must meet Georgia's mandatory residential, plumbing, electrical and energy codes. Georgia law applies those codes to all construction whether or not the local government enforces them. Georgia amends section R311.2.1 so that every new dwelling unit must have carbon monoxide alarms, not only homes with fuel-burning appliances or an attached garage. Georgia amendments do not require fire sprinklers in a one- or two-family dwelling, citing O.C.G.A. 8-2-4. A new accessory dwelling unit, detached or added on, is new residential construction. It normally needs a building permit with full plans, plus separate electrical, plumbing and mechanical permits, and zoning approval for a second unit on the lot. Utility connections (water, sewer or septic, and electric service) are usually reviewed as part of the permit, so ask about capacity and connection fees early.
