The weight referred to in most municipal codes is the vehicle GVWR. Confirm it with your municipal code. If your vehicle does not meet the criteria of a "commercial vehicle" as defined below, you should be o.k.
" Commercial motor vehicle, when applied to stopping/standing/parking, means a vehicle of a type required to be registered under the State Vehicle Code, and used or maintained for the transportation of persons for hire, compensation or profit, or designed, used or maintained primarily for the transportation of property. Passenger vehicles which are not used for the transportation of persons for hire, compensation or profit are not commercial vehicles."
