Vehicle classification comes first
Section 17-159f includes non-self-propelled sleeping vehicles under 35 feet only when currently registered and ready for highway use. Vehicles 35 feet long or longer are treated as structures, not RVs. The pickup-camper, van and motorhome passenger-vehicle exception uses the wording “not more than 25 feet long or 11 feet high.” Those classes are excluded from this narrow trailer checker rather than silently changing that wording or resolving its interpretation.
Winter location and setbacks
From October 16 through April 14, covered RVs may not be stored between the street and the front line of a building or within one-half of the required minimum side or rear yard. Each actual side and rear setback must meet its own half-yard requirement. The required yards depend on the parcel’s legally applicable zoning; the checker does not substitute one universal footage. April 15 through October 15 is outside this seasonal placement calculation, not an automatic permission period.
One boat and one other RV
No more than one boat, with or without its trailer, and one other RV may be stored on a lot unless the additional vehicles are inside a totally enclosed and roofed structure. This is not a two-trailer allowance. The outdoor count includes the proposed trailer; wholly enclosed units use a separate route.
Narrow exceptions and vacant parcels
In R-50, R-75 and R-100, a unit may be closer to a side or rear line when the angle from predominant ground level at the property line to the top of the vehicle is no greater than 45 degrees. This exception is not automatically approved. If no residence exists on the parcel, no RV may be stored in any required yard setback. Vacant parcels, the angle exception, special districts, occupied use and utility work are outside the checker.
Who to contact for your setup
No motorhome/passenger-class interpretation, summer allowance, 45-degree exception, vacant parcel, street, sleeping, utility or development approval. Limited administrative screening only; not a permit or complete legal approval.
Use the Hopewell Township (Mercer County) parking checker to organize the starting conditions. The checker cannot approve a parcel, a variance or an unverified exception.
