What This Site Does
Irrigation Permit Guide is a free reference resource for U.S. homeowners and contractors who need to understand residential irrigation system permit requirements. We cover all 50 states, with dedicated guides for backflow prevention, contractor licensing, homeowner exemptions, permit costs, and annual testing requirements.
Before installing, expanding, or modifying a lawn sprinkler or drip irrigation system, most homeowners need to answer three questions: Is a permit required? Who can legally do the work? What backflow device is required? This site exists to answer those questions clearly, without requiring a phone call to a government office just to find out where to start.
Why We Built This
Searching for irrigation permit information online returns a fragmented mix of county PDFs, contractor blog posts, Reddit threads, and outdated municipal FAQs. No single resource mapped the landscape clearly across all states. We built Irrigation Permit Guide to change that — one well-researched state guide at a time.
Our approach is to go deeper than the first page of Google results. We read state statutes, water utility cross-connection control programs, and state agency guidance documents to build guides that reflect what the rules actually say — not just a generic yes/no answer.
Editorial Standards
Every state guide on this site is researched against primary sources: state statutes, agency rules (TCEQ, FDACS, IEPA, and equivalent bodies), and water utility cross-connection control program documents. We cite the governing body for each state's rules so you can verify the information directly.
We update guides when rules change. If you find an inaccuracy — a regulation that has changed, a local rule we missed, or a detail that needs correction — please contact us. We take corrections seriously and update promptly.
What We Are Not
Irrigation Permit Guide is an informational resource, not a legal or professional advisory service. Nothing on this site constitutes legal advice, plumbing advice, or professional engineering guidance. Always verify current rules with your local building department and water utility before starting any work. Permit requirements change, and local rules sometimes differ from state baselines.
