City Ordinance Compliance Requirements
Metal detecting in Mountain House requires maneuvering through both local city ordinances and the oversight of the Mountain House Code Compliance Division, which issues permits and reviews compliance with local ordinances and Master Restrictions.
Before you head out with your detector, you’ll need to review Mountain House city ordinances specific to metal detecting activity. Local regulations vary by jurisdiction, so don’t assume rules from neighboring areas apply here.
The Code Compliance Division serves as your primary point of contact for permit issuance and ordinance interpretation. You’re also responsible for documenting your location and planned activity when submitting permit applications.

Once you’re in the field, activity tracking becomes equally important. Record each site you visit, the items you find, and any holes you dig and refill. If you recover artifacts over 50 years old, your records must reflect that you reported them to the appropriate authorities.

Where Metal Detecting Is Legal in Mountain House Parks
Metal detecting in Mountain House parks is legal in a handful of designated areas, including beach zones, developed park lawns, and shallow saltwater areas. These zones give you room to apply various metal detecting techniques while staying within legal boundaries.
However, not every park welcomes detectorists. Contra Loma Regional Park prohibits metal detecting in all zones, so you’ll want to confirm access before visiting any specific location.
Not all parks allow metal detecting — Contra Loma Regional Park bans it entirely, so always verify access beforehand.
State parks are generally off-limits, particularly where historical artifacts or protected cultural resources exist. Natural parkland areas, wilderness zones, and regional preserves are completely restricted.
You’re permitted to collect modern coins and money from public lands, but anything over 100 years old must stay in place. Always verify local regulations with park authorities before you begin your search.
Parks and Zones That Are Off-Limits in Mountain House

Knowing where you can detect is only half the picture — understanding the restricted zones keeps you out of legal trouble. Several off limits areas apply throughout California’s park system, and Mountain House is no exception.
Natural parkland areas, wilderness zones, and regional preserves prohibit metal detecting entirely. Archaeological and historic sites — including old cabins, mining areas, and gravesites — are completely off-limits.
Contra Loma Regional Park enforces a full prohibition across all its zones. State parks generally restrict access unless a specific permit authorizes use.
Private property, including hotel beaches, is another restricted zone you must avoid. California law also prohibits digging or disturbing vegetation statewide.
Before you head out, verify current local ordinances with Mountain House authorities to confirm which specific areas remain inaccessible.
Digging Rules and Depth Limits You Must Follow
Even if you’ve secured the proper permits, you still need to follow strict digging rules before you break ground. California law prohibits digging holes or disturbing vegetation statewide, but park authorities generally allow small, clean holes that comply with posted regulations.
Among the most critical metal detecting tips: always refill and restore any hole you dig, leave no visible trace, and never uproot plant life.
Your digging techniques must stay shallow — depth limitations confine all detecting activity to surface-level and shallow water areas. Deeper excavations immediately cross into illegal territory.
Time restrictions may also apply depending on the season and specific park location. Violating these rules risks permit revocation and legal consequences, so treat every dig site with precision and responsibility.
What You Can Legally Keep After a Find in Mountain House Parks

Once you’ve made a find in Mountain House parks, California law draws a clear line between what you can pocket and what you must surrender. Modern coins and currency from public lands are yours to keep.
However, artifact reporting becomes mandatory when you uncover items over 50 years old — those belong to the state. Anything exceeding 100 years old can’t be legally removed, period.
Within East Bay Regional Parks, you must hand recovered items over to a Park Supervisor or Public Safety Officer.
Metal detecting ethics aren’t just courtesy — they’re legally enforced here. Violating artifact reporting obligations exposes you to criminal liability under California Penal Code Section 485.
Know the rules before you dig, and you’ll keep your freedom intact.
What California Law Says About Old Artifacts Found While Metal Detecting
California law treats old artifacts as protected property, not personal treasure. Once you uncover something in the ground, artifact age determines your legal responsibilities immediately.
Items over 50 years old are considered state property, meaning you must report them to authorities rather than pocket them. If something exceeds 100 years old, you can’t legally remove or collect it under any circumstances.
California Penal Code Section 485 reinforces this obligation by requiring you to surrender valuable found items to law enforcement. Within East Bay Regional Parks specifically, you must turn discoveries over to Park Supervisors or Public Safety Officers.
Modern coins remain the exception—you’re free to keep those. Understanding these boundaries before you dig protects you from serious legal consequences that could end your detecting privileges entirely.
What to Bring and Document Before Your First Hunt in Mountain House

Before your first metal detecting hunt in Mountain House, you’ll need to gather the right permits and documentation to stay compliant with local regulations.
Secure your East Bay Regional Park District permit through EBParks.org/Register or by calling 1-888-327-2757, option 2. Review Mountain House city ordinances and verify your target location isn’t a restricted zone.
Document your planned activity area, permitted dates, and contact information before heading out.
Best practices include carrying your permit on your person at all times and photographing your search area before and after detecting.
Pack your metal detecting gear alongside a finds pouch, a small hand trowel for compliant shallow digging, and a notebook to log any discoveries.
Proper documentation protects your legal standing and keeps your hunt legitimate.
