Bergen County, New Jersey has no countywide zoning or building department: each municipality administers its own zoning and construction permits under state law12. Covered work still requires a permit under New Jersey's Uniform Construction Code, and the current building subcode is the New Jersey edition of the 2024 International Building Code34. Where septic is used, the county health department reviews it5.

Do you need a building permit in Bergen County, New Jersey?
Yes, and who issues it depends on which Bergen County municipality contains the property, since New Jersey has no unincorporated county land and counties have no general building authority of their own113. The New Jersey Uniform Construction Code requires a permit before covered construction, enlargement, repair, renovation, alteration, reconstruction, demolition or change of use begins3. The current building subcode is the New Jersey edition of the 2024 International Building Code, adopted August 17, 20264. Hackensack's municipal department handles construction permit inspections as well as zoning and other land-use responsibilities, but another municipality will have its own office141.
Who issues building permits in Bergen County, and how do you reach them?
There is no single Bergen County building department: each municipality runs its own, so confirm the right office for your specific city, borough, town or township before you call anyone1. As one example, the City of Hackensack's Construction Official reviews and issues building permits for that city only, reachable at 65 Central Ave, Hackensack, NJ 07601, phone (201) 646-3920 ext. 2001, or email [email protected]15. Hackensack's Department of Building, Housing and Land Use is organized into building inspection, property maintenance and community development divisions, and also serves as the administrative arm of the city's planning and zoning boards15. If your land is in a different Bergen County municipality, search that municipality's own website for its construction official and zoning officer instead of using Hackensack's contact information1.
Does Bergen County have zoning?
Not at the county level. New Jersey's Municipal Land Use Law gives zoning power to municipalities rather than counties, so Bergen County itself has no zoning ordinance or zoning authority16. Hackensack's municipal department handles zoning, planning and construction permit inspections, but that fact applies only inside Hackensack and does not establish the rules in another Bergen County municipality14. Minimum lot size, minimum dwelling size, setbacks, lot coverage and building height are set district by district in each municipality's ordinance; New Jersey law authorizes local variation but sets no single statewide number for them91681718. A county-run pilot construction-code program exists in New Jersey, but it is limited to qualifying county-owned buildings or shared-service arrangements rather than private residential land generally13.
How do septic permits work in Bergen County?
Most of Bergen County is on public sewer, so septic systems are the exception rather than the rule here5. Where a property does use a septic system, the Bergen County Department of Health Services conducts the plan review and permitting under New Jersey's statewide septic rules rather than each municipality doing it separately519. Reach the department at One Bergen County Plaza, 4th Floor, Hackensack, NJ 07601-7076, or by phone at 201-634-260019. Before you assume a rural-feeling Bergen County parcel can use a standard septic system, check both with the county health department and with your municipality's construction official, since a building permit still needs municipal zoning sign-off even when septic itself is a county-level review1915.
Can you live in an RV or tiny home on your land in Bergen County?
We could not confirm a Bergen County or state rule that specifically addresses RV or tiny-home occupancy on ordinary residential land; because zoning is entirely municipal here, this is a question for your specific city, borough, town or township's zoning officer, not a countywide answer61. A manufactured (HUD) home in New Jersey is limited to single-family use, must meet federal installation standards, and is inspected by a HUD-approved third-party inspector rather than the local building department alone11. Short-term rentals are also a municipal matter: New Jersey lets a municipality license and tax short-term rentals of less than 175 consecutive days, with the occupancy tax generally capped at 3%, but whether short-term or RV-style stays are allowed at all still depends on your specific municipality's own ordinance20.
Building a home in Bergen County: the steps, in order
- Identify which Bergen County municipality your parcel is actually in, then find that municipality's own construction official and zoning officer; Hackensack's office here is only an example, not the countywide contact151.
- Confirm your specific zoning district's minimum lot size, setbacks, lot coverage and height limits with that municipality's zoning officer before you design anything218.
- If your lot is not on public sewer, contact the Bergen County Department of Health Services about septic plan review before you finalize a house design195.
- File your construction-permit application with your municipality's construction official; work cannot begin until all required state, county and local approvals are in place1522.
- Keep your application active: an unresolved permit application is deemed abandoned six months after filing unless it is being diligently pursued or a permit has already issued22.
- Schedule required inspections as construction proceeds; work must stop at set points, including before footings are poured and before framing is covered, so the code official can inspect23.
- Identify who controls the road at the parcel entrance. A proposed residential driveway on a Bergen County road carries a $250 road-access review fee when it is not subject to site-plan approval or exemption12. Access onto a State highway requires a separate NJDOT permit24.
What to check before you buy land in Bergen County
Confirm which Bergen County municipality governs the parcel and read that municipality's zoning ordinance, since the county sets no zoning, lot-size, setback or height rules16. Ask whether the lot has public sewer; if not, only about 11.7% of Bergen County's sampled soil has no severe limitation for a conventional septic drain field, so budget for a site-specific review and contact the Bergen County Department of Health Services early2519. Verify whether the entrance is on a municipal, county or State road: a qualifying proposed driveway on a county road has a $250 review fee, while State-highway access requires NJDOT approval1224. Bergen County's population density is about 4,114 people per square mile26. Typical property tax bills run about $10,001 a year at an effective rate near 1.7%, and the median home value is roughly $791,116272829.
Watch-outs
- Bergen County has no countywide zoning, building-permit or septic rule; every answer depends on which of Bergen's cities, boroughs, towns or townships your parcel is in, so confirm with that specific municipality before you rely on any county-level answer16.
- We could not confirm a Bergen County or state rule on living in an RV or tiny home on your own land; this is entirely a municipal zoning question here, so ask your specific municipality's zoning officer directly1.
- Only about 11.7% of Bergen County's sampled soil has no severe limitation for a conventional septic drain field, so if a parcel is not on public sewer, budget for an engineered system and get the Bergen County Department of Health Services involved early2519.
- A driveway onto a Bergen County road can trigger a separate $250 road-access review fee when the proposal is not covered by site-plan approval or exemption12.
