How Washington County’s Permit System Applies to Grant
If you want to metal detect in Grant, you must obtain a Washington County permit, which applies specifically to designated swim beaches.

When detecting, you’re required to stay within the permitted beach areas and follow all county-imposed conditions, including depth and time restrictions.
Washington County Permit Requirements
Since Grant is located within Washington County, its permit requirements directly govern metal detecting activity in the township’s county-managed parks and designated swim beaches.
Your permit application must be submitted before you deploy any detection techniques at authorized locations.
Washington County enforces these three core requirements:
- Metal detecting is restricted to designated swim beaches only.
- Activity hours are limited to 6am–8pm, with a maximum six-inch digging depth.
- No sharp tools, trenches, or holes are permitted during recovery.
You’re also liable for any damage you cause while detecting.

Permits remain valid from Memorial Day through Labor Day, keeping your detecting season clearly defined and legally protected.
Grant’s Designated Swim Beaches
Washington County’s permit system only authorizes metal detecting at designated swim beaches, so knowing which locations in Grant actually qualify under that framework determines where you can legally detect.
Grant sits within Washington County, but not every waterfront or park automatically qualifies as a permitted swim beach under county swim beach regulations. You must confirm that your specific target location carries an official designated swim beach status before applying for your permit.
Once you’ve verified eligibility, follow standard detecting safety tips: stay within the six-inch depth limit, avoid sharp digging tools, and never leave open holes or trenches.
Your permit remains valid only from Memorial Day through Labor Day, restricting your window to summer months. Operating outside designated beaches or beyond permitted hours exposes you to fines up to $500.
Seasonal Permit Validity Dates
Once you’ve secured your Washington County permit, you’ll need to understand that it carries a strict seasonal window: Memorial Day through Labor Day only.
Detecting outside this window violates your permit terms and exposes you to fines. Monitor seasonal permit changes annually, as Washington County may update terms.
Key restrictions governing your permit window:
- Active dates: Your permit authorizes detecting only between Memorial Day and Labor Day at designated swim beaches.
- Operating hours: You’re restricted to 6am–8pm daily throughout the valid season.
- Permit application process: Submit your application before Memorial Day to avoid losing early-season detecting days.
You’re responsible for knowing your permit’s exact dates.
Expired permits provide zero legal protection during off-season detecting activities.
