Building permits, zoning and septic rules in Marlboro Township, New Jersey

Marlboro Township, New Jersey requires a building permit for most construction, issued by the Township's own Construction Division under the State Uniform Construction Code.12 The Township also writes and enforces its own zoning through its Zoning/Code Enforcement Division.3 Septic and well approvals sit with a health authority, which we could not confirm for Marlboro; ask the Township's construction office.

Do you need a building permit in Marlboro Township, NJ?

Yes in nearly every case. Marlboro Township's Construction Division states that building, remodeling or adding onto a house or business must follow the State Uniform Construction Code and generally requires a building permit.14 The Township runs its own Uniform Construction Code enforcing agency, so permits are issued in town rather than by Monmouth County.2 Permitted work is inspected in phases, and a final inspection is required when the job is complete.10 A new building also needs a certificate of occupancy from the construction official before anyone uses or lives in it.8

An owner may do their own work in all four trades and draw their own plans in the house they live in and own, if they provide a detailed drawing.7 A person building a new home must file an owner-builder affidavit with the construction official before a certificate of occupancy can be issued.11

Who issues building permits in Marlboro Township, and how do you reach them?

The Marlboro Township Construction Division issues building permits and does the inspections; call 732-536-0200.4 The Division asks you to visit or call during planning, before construction, so you learn whether you must also appear before the planning board or zoning board of adjustment.1 Building permits then go to the zoning office for approval after the Construction Division has reviewed them for completeness.5 Fees follow the Township's fee schedule: state rules set municipal plan-review fees between five percent and 25 percent of the construction-permit fee.12

Does Marlboro Township have zoning, and what does it mean for lot size and height?

Marlboro Township adopts and enforces its own zoning ordinances through its Division of Zoning/Code Enforcement, so zoning here is a township matter, not a county one.3 Zoning permits and approvals may be required depending on the use or construction, and some applications go to the Planning Board or Zoning Board of Adjustment.3 Subdivisions and site plans go through the Planning Board.13

Standards depend on the district. In the A/LC Agriculture/Land Conservation District, single-family dwellings are limited to 5% lot coverage and 35 feet in building height.1415 In the R-10AH Residential District, principal buildings may be 30 feet tall and accessory buildings 15 feet.16 Ask the Zoning Officer for the district, setbacks and minimum lot size that apply to your parcel.

How do septic permits work in Marlboro Township, NJ?

New Jersey requires the board of health with jurisdiction to certify a proposed septic system before any building permit can be issued or construction begun.6 The septic tank or field must also be inspected and cleared for covering by the board of health's representative before it is buried.17 Monmouth County's Office of Public Health handles septic approvals for its member municipalities, but not necessarily every town in the county.18 We could not confirm which health authority serves Marlboro Township, so ask the Township's construction office or call the Monmouth County Office of Public Health at 732-431-7456.19

Where public sewer is available and the existing system is no longer suitable, state rules can require connection.20

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

We could not confirm a Township rule on living in an RV, camping on private land or occupying a tiny home. Ask the Marlboro Township Zoning Officer before you buy, at 732-536-0200.5 Manufactured (HUD) homes are limited by state rule to single-family dwellings in use group R-5 and must meet federal installation standards.21 Any dwelling intended as a home also needs its own certificate of occupancy before use.8

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

  1. Call the Zoning Officer to confirm your district, setbacks and whether a variance or Planning Board review is needed.5
  2. Get septic and well approvals from the health authority with jurisdiction; they come before the building permit.6
  3. Apply to the Construction Division for the building permit; the zoning office then reviews it.45
  4. Build with inspections of each phase and a final inspection.10
  5. Obtain the certificate of occupancy before moving in.8

What stays with Monmouth County, and what should you check before you buy?

Monmouth County does not zone land; the type and intensity of use is set by municipal zoning.22 The county does review certain subdivisions and site plans affecting county roads and drainage, but one- and two-family residential site plans are exempt from that committee's review.23 A driveway onto a state highway needs a state access permit from NJDOT.24 Private wells need a state drilling permit and a municipal or county health permit.9

Costs: Monmouth County's effective property tax rate is 1.8% and the median bill is $10,001 per year.2526 For land outside Marlboro Township, see the Monmouth County page.

Watch-outs

  • Marlboro Township's rules on RV occupancy, accessory dwellings and tiny homes were not confirmed, so ask the Zoning Officer in writing before relying on any plan.5
  • The health authority that approves septic systems and wells in Marlboro Township was not confirmed; New Jersey requires that approval before a building permit issues.6
  • Owner-builder rules do not remove construction permits: the personal-use exception applies to builder registration, not permits or inspections.27
