Martin County, FL Parking Rules: RV & Boat Parking (2026)

Sec. h treats RV, boat trailer and similar recreational-vehicle storage as an accessory use permitted alongside a residence in the county's Category 'A,' 'B' and 'C' zoning districts, which cover the standard single-family and residential zones. The list of equipment the rule covers is specific: boat trailers, camping trailers, travel trailers, motorized dwellings (motorhomes), tent trailers and horse vans. Two conditions apply. First, none of that equipment may be used for living, sleeping or other occupancy while it is parked on the lot, so a resident cannot let a relative live in a parked travel trailer or motorhome.

Second, any of that equipment longer than 25 feet cannot be parked or stored within the lot's side or rear setback area; it has to sit within the buildable envelope of the lot, typically the driveway or front yard area outside the setback. A related provision, Sec. i, separately allows storage of one commercial vehicle or trailer up to one-ton cargo capacity if it belongs to the resident and is garaged or screened from view of neighbors and the street, though public-safety and emergency-service vehicles are exempt from that screening rule.

Both provisions sit within the broader accessory-use standard, Sec. B, which requires that no accessory use or structure be established on a lot before all permits for the principal residence have been issued.
