Well permits, explained state by state
Five different regulatory models cover the 50 states. Knowing which one you're in tells you who files, what it costs, and how long you'll wait.
"Do I need a permit to drill a well?" has fifty answers, but they cluster into five models. We verified all of them against state statutes and agency portals in July 2026 — the live version powers our permits index.
Model A — state permit with a real online portal
One agency issues the permit statewide, and the application is genuinely submitted online: New Jersey (DEP, and only the licensed driller may e-file), Delaware ($250), South Carolina ($70 notice with 48-hour review), Wyoming ($50), Washington (notice of intent, $200+), Oregon (start cards, electronic-only since 2024), Minnesota ($325 notification), Wisconsin ($50.50), Idaho, Utah, Arizona. If you're in one of these, the paperwork is fast and trackable.
Model B — state filing, paper or email
The state issues it, but you're mailing or emailing documents: Colorado (~$100, up to 49 days), New Mexico ($125 at a district office), Hawaii ($300 and up to 90 days for commission action), Nevada, Alabama, Tennessee ($75 notice).
Model C — your county or town runs it
The state sets standards; the local health department issues the permit. North Carolina (all 100 counties, 30-day statutory clock, $340–$800), California (each county its own enforcing agency), Ohio, Michigan, Illinois, Iowa (the owner applies), Virginia, West Virginia, Maryland, Connecticut and Massachusetts (town by town). Fees, forms and whether you can apply online vary by county — that's exactly what our county pages cover.
Model D — districts, not states or counties
Florida's five water management districts permit every well and all take applications online — often approved in days. In Texas there's no state pre-drill permit for exempt domestic wells, but roughly a hundred groundwater conservation districts require registration or authorization before drilling inside their boundaries.
Model E — no pre-drill permit at all
Pennsylvania, Alaska, Oklahoma, Kentucky, Arkansas, Missouri, Montana, the Dakotas, most of New England and others: the state licenses the driller and requires a completion report or registration after construction — sometimes within tight deadlines (Rhode Island: 10 days). "No permit" never means "no paperwork."
Who's allowed to file
This is the part that surprises homeowners: in several states the licensed driller is the only lawful submitter (New Jersey's rule is explicit; Oregon's start card is the constructor's duty). Elsewhere the owner or the owner's agent signs (Virginia), or the owner applies directly (Iowa, West Virginia, Colorado). Your driller deals with this constantly — a good one will name the authority, the fee and the clock in the quote.
