Zoning, building permits and septic rules in Mannington Township, New Jersey

Mannington Township, New Jersey sets its own zoning through its land development ordinance, Chapter 701. Building code enforcement is not run by the township: the township handed it to the New Jersey Department of Community Affairs2. Septic permits for homes in Salem County come from the county health department's Environmental Division3.

Does Mannington Township, NJ have zoning?

Yes. Mannington Township divides its land into zoning districts under Chapter 70 of its code, the land development ordinance1. The districts include agricultural (A), rural residential (RR), medium-density and high-density residential, commercial and industrial, and a conservation district; boundaries are drawn on the township's zoning maps8. Salem County itself does not zone, so the township ordinance is the one that governs a parcel here9.

Which district a lot sits in decides lot size, setbacks and height, so confirm the district with the Zoning Officer before you buy. The township's Chapter 70 also regulates subdivision of land10, and a minimum dwelling size applies in new construction, set by a schedule we could not review11.

What lot size, setbacks and height limits apply in Mannington Township?

The general district tables were not available to us, so ask the Zoning Officer for the schedule for your district. What we can confirm covers older vacant lots only.

A vacant, lawfully created Agricultural-district lot of at least 60,000 square feet that existed unchanged on November 1, 2007 can take a single-family house with 200 feet of width and depth12. Yards on such a lot are 50 feet front, 25 feet side and 50 feet rear for the house13, with coverage capped at 15 percent for buildings14 and height at 35 feet for the house15.

A comparable Rural Residential lot of at least 2 acres from the same date needs 200 feet of width and depth16, 25 feet side yards for the house17 and no more than 10 percent building coverage18.

Do you need a building permit in Mannington Township, and who issues it?

Yes, New Jersey requires a construction permit for any new construction and for structural, plumbing, mechanical and electrical work on existing buildings4. In Mannington Township, the township does not run its own construction office: its code transfers enforcement of the state Uniform Construction Code to the New Jersey Department of Community Affairs2. The township's website lists a state-run construction code office with a main number of 609-567-365319.

The zoning step is separate. The township's Zoning Officer takes zoning permit applications for $50 with a plot plan showing distances from property lines and other structures, and certificates of occupancy are handled at the same office5. State rules say no construction permit issues until required local approvals are in place20. We could not confirm how the state office handles inspections in Mannington; ask the number above.

How do septic permits work in Mannington Township?

Septic permits for Mannington Township addresses come from Salem County, not the township. County inspectors review applications and issue permits for septic systems, and they inspect installations21. The county reviews applications under state standards3.

New Jersey law bars any building permit until the board of health certifies the proposed water supply and sewage facilities22, so septic approval comes early in the sequence. A tank or field cannot be covered until a health representative inspects it23. Soil matters in Salem County: only about 0.1% of the county's soils rate as not limited for a conventional drain field, so expect a site evaluation and possibly an engineered system24. A new private well needs an NJDEP permit before the county well application6.

Can you live in an RV or tiny home in Mannington Township?

We could not confirm. The township code has a trailers chapter and a campgrounds section that we have not been able to review, so do not assume either way. Ask the Zoning Officer, whose office takes zoning permit applications5, before you move any RV, tiny home or manufactured home onto a lot.

One statewide point applies to manufactured homes: HUD-code manufactured homes are limited to use group R-5, single-family dwellings25.

Building a home in Mannington Township: the steps, in order

  1. Ask the Zoning Officer which district the lot is in and whether it qualifies under the older-lot rules5.
  2. Apply to the Salem County Environmental Division for septic approval, and for a well if there is no public water21.
  3. Submit the zoning permit application with a plot plan5.
  4. Apply for the construction permit through the state-run code office; a complete application must be released or denied within 20 business days26.
  5. Call for the required footing, framing and other inspections as work proceeds27.
  6. Owner-builders file an affidavit with the construction official before a certificate of occupancy can issue7.
  7. Get the certificate of occupancy5.

What stays with Salem County, and what to check before you buy in Mannington Township

Salem County reviews subdivisions and site plans in addition to township approval28. Septic and well permits stay with the county health department21. A driveway onto a Salem County road needs a County Road Access Application29. For rules on land outside the township, see the Salem County page.

Before buying, check three things. Ask the Zoning Officer about the district and any pending change, because a township ordinance proposed to remove the conservation district was introduced but we could not confirm its adoption8. Ask about flood hazard areas, which the township code covers but we could not review. And note Salem County's effective property tax rate is about 3%30.

Watch-outs

  • A proposed ordinance (26-07) to remove the conservation district was only reported as introduced, and we could not confirm that it was adopted, so confirm the current districts with the Zoning Officer8.
  • The lot-size, setback, coverage and height figures above apply only to older vacant lots, not every lot in the district12.
  • The Zoning Officer's posted hours are Wednesday mornings, so plan ahead5.
  • We could not confirm township rules on RVs, tiny homes, accessory dwellings, driveways within the township, flood hazard areas or fees; call the Zoning Officer5.
