Flood zone by address
ParcelSheet reads FEMA's National Flood Hazard Layer at the lot: the zone, whether it is a high risk area where lenders ask for flood insurance, and the base flood elevation where FEMA lists one. FEMA's countywide study for Burlington County has 192 FIRM panels, the newest effective August 2019; coastal V zones, where waves add to the flood, are mapped along its shore.
The official panel and any Letter of Map Amendment are at FEMA's Map Service Center. An elevation certificate for a Burlington house comes from a licensed surveyor and is often on file with the county or city building office.
Property lines
The parcel outline, parcel number and mapped size come from the New Jersey statewide parcel map (NJ Office of GIS cadastral layer with the MOD-IV tax list), so a Burlington lot shows the same lines the municipal tax maps draw. Burlington County covers about 511,547 acres of land and 13,488 acres of water.
Mapped lines are approximate. The Burlington County Board of Taxation keeps the parcel record (Burlington County website); every county's office is on the state's county boards of taxation list; a licensed surveyor sets the true corners.
Zoning
In New Jersey zoning is set by each municipality, not by the county. ParcelSheet shows the use code on the lot's parcel record and the municipality it sits in; the municipal zoning office has the district, the uses it allows and the lot size it needs. The Burlington County website lists the county's municipalities.
ADU and guest houses
The New Jersey Municipal Land Use Law (N.J.S.A. 40:55D) lets each municipality allow an accessory dwelling unit on a lot with a house. Whether a Burlington lot can add one depends on its district; the municipal zoning office has the rule. ParcelSheet shows the mapped lot size and the ground's slope, the first two things the question turns on.
Septic and soil
ParcelSheet reads the USDA soil survey at the lot: the soil's name, its septic absorption rating and whether it is prime farmland. Burlington County is soil survey area NJ005, Burlington County, New Jersey, last updated August 2026, on Web Soil Survey.
A new or changed septic system in Burlington County needs a permit from the Burlington County health department under the NJDEP septic rules (N.J.A.C. 7:9A), which tests the soil on the lot itself.
Setbacks
Setbacks in Burlington County come from the zoning district: the front, side and rear distances a house must keep. ParcelSheet does not draw setback lines; the municipal zoning office gives them for the lot's district.
