Nassau County, FL Parking Rules: Commercial & Oversized Vehicles (2026)

05, 'Parking of heavy vehicles in residential districts,' flatly prohibits parking heavy vehicles, defined by example as tractors, trucks and school buses, in any residential zoning district. The section reaches beyond size alone by naming specific Florida license plate classifications, CV (commercial vehicle), GW (gross weight), KS and P, tying the ban to how the state itself classifies the vehicle's registration rather than leaving 'heavy vehicle' to interpretation on the ground. The only carve-outs are functional and temporary: a heavy vehicle may be present in a residential district while it is actually loading or unloading, or for the time normally needed to service a dwelling or another use or structure that is itself permitted in that residential district.

There is no provision allowing an owner to park a personal work truck or box truck overnight or long-term simply because it is titled to a resident; the exception is tied to the vehicle actively performing loading, unloading or service work, not to ownership or convenience. 01(A)), it does not vary by specific residential zone the way yard and height standards do.
