About This Tool

The Irrigation Permit Checker uses a state-by-state database of irrigation permit requirements to give you a quick orientation on what your project likely requires. Because permit requirements can vary at the city or county level within each state, this tool provides state-level guidance. Always confirm requirements with your local building department and water utility before starting work.
