North Brunswick in Numbers
Of the three Brunswick townships, North Brunswick is the smallest in land and the most crowded: about 12 square miles holding close to 3,650 people per square mile at the 2020 count, which is well above East Brunswick and roughly three times South Brunswick. It has also kept growing, from 43,905 residents in 2020 to an estimated 45,097 by mid-2025. A little over four households in ten rent their home here, a higher share than in East or South Brunswick, so a North Brunswick sale is fairly likely to involve a house with tenants in it.

Figures from the Census Bureau's QuickFacts profile of North Brunswick township.
A township median is a starting point and nothing more. A townhouse with a newer roof and a single-family ranch with a finished basement that never had a permit will be priced on their own facts. We see the property once and put a single number on paper, and that number already accounts for the certificates described below.
The Home Sale Certificate: Your Permit History, Checked
Before a North Brunswick home changes hands, the Building Division reviews its permit and inspection record and issues a Home Sale Certificate. The review asks three things: whether any construction permit is still open, whether every required inspection and final approval was completed, and whether work went ahead without the permit it required. The township is blunt about the most common trap: finishing a project does not close its permit. Until the final inspection is passed, the permit stays open and the certificate waits.
The owner signs the application in front of a notary, attesting that completed projects meet their permits and the Uniform Construction Code. The fee is $125 for a condo, townhouse or mobile home and $150 for a single-family house. The form asks whether a central air unit, furnace, boiler or water heater was replaced in the last ten years, and whether the home has a generator, radon system, addition, finished basement, fireplace or wood stove, pool, hot tub or a shed over 200 square feet, each with its permit number. Once issued, the certificate lasts 120 days, and one administrative extension of no more than 30 days is possible; if the house is still unsold at that point, the owner applies again.
Two details matter to sellers. Permits pulled during this process, and the approvals that follow, are passed to the Tax Assessor, so a finished basement or addition that was never on the books can produce an added assessment. And inspections are now booked in writing through the township's SDL portal, with part-time inspectors working set windows, so an old open permit can take a while to close.
The township accepts a waiver letter, on law-firm letterhead from the buyer's attorney, in which the buyer takes responsibility for obtaining the Home Sale Certificate and correcting any code problems after closing. Until the certificate issues, the buyer may only do the corrective work and cannot move in. That is how we usually buy a house with permit loose ends: the open items become our job, not a list of repairs you have to finish before you can close.
The Fire Marshal's Alarm Inspection
The second certificate comes from the Fire Marshal's Office (732-247-0922, ext. 453), which inspects the smoke and carbon monoxide alarms and issues a Certificate of Compliance. Its written requirements are specific. There must be a working smoke alarm on every level, basement included but not attics or crawl spaces, and one outside each sleeping area. Any battery-powered smoke alarm must be a sealed ten-year unit, and a hardwired system that already exists has to be kept, not swapped for battery units. A carbon monoxide alarm must sit within ten feet of every bedroom.
You pay when you apply, and the fee depends on how soon you need the visit: $50 with ten business days' notice, $100 for six to nine days and $150 for five. A two-family house adds $50, as does each extra unit in a larger building, and a missed appointment or re-inspection costs $25. The certificate is not transferable and expires 60 days after it is issued, so it has to be timed close to settlement. When you sell to us, we schedule it, buy any alarms that are missing and meet the inspector.
Property Taxes and the Collector's Office
Taxes are billed and collected by the Tax Collector in the Municipal Building at 710 Hermann Road (732-247-0922, ext. 460, weekdays 8:30 to 4). As in every New Jersey town, installments come due as each quarter opens, in February, May, August and November. The same office runs the township's yearly tax sale for unpaid taxes and other municipal charges and keeps the record of tax sale certificates held by the township or by outside investors, so it is the place that issues a redemption figure if a lien has been sold on your property.
On the state's 2025 figures, North Brunswick's general tax rate was 6.571 and its effective rate 2.352 per $100 of value. At closing, the title company pays any arrears or redemption amount from the price and prorates the current quarter between you and us. A lien does not stop a sale; our tax lien guide explains how the payoff works.
Water and Sewer: The Final Reading
Water and sewer service in North Brunswick is a township utility, billed monthly. The sewer charge is worked out from the water the meter records, and a fixed facility fee based on meter size sits on top. Payments go to the Utility Billing Office on the second floor of the Municipal Complex.
At a sale the township does not turn water off and on. It simply moves the account from one name to another, and that requires a final meter reading scheduled through the Water Services Office. The reading is taken from an AMI Neptune meter; if the house still has an older manual meter, the township will speed up a replacement so the transfer can go through. A reading requested off the regular cycle carries a $25 fee. To put the account in the buyer's name, the office needs the Closing Disclosure or settlement statement, or the first page of the recorded deed. We request the reading and send the paperwork.
Landlords should know one more rule: the township treats the owner as responsible for every water and sewer charge on the property, citing N.J.S.A. 40:14B-21, regardless of what the lease says, and it will not shut off service because a tenant stopped paying. If a tenant left a balance behind, it is cleared from what you receive at closing.
Selling a Rental in North Brunswick
Chapter 266 of the township code requires every rental property to be registered every three years. Registrations are due October 1 and expire on the third September 30 after filing. The fee is $30 per property, not per unit, and the filing needs a current liability insurance certificate and, where the law calls for it, a lead-safe certification. Code Enforcement inspects at first registration and at every change of tenant: $50 normally, $70 if the new tenants have already moved in or the registration has lapsed. Multi-family buildings are also inspected on a five-year cycle.
Tenants can stay put when we buy; each lease simply continues with us as landlord, and their security deposits plus interest transfer at closing with the written notice state law requires. A lapsed registration or a missed turnover inspection is something we can put right after we own the property. Our New Jersey rental sale guide covers the rest.
How a North Brunswick Sale With Us Goes
- You give us the address and the history: renovations, permits you remember, tenants, anything the township has sent you.
- One walk-through, then a written price, usually within 24 hours.
- After signing, we pull the permit file, file for the Home Sale Certificate or the waiver, book the Fire Marshal and order the final water reading.
- Settlement runs through a New Jersey title company or attorney: your loan, tax arrears and water account are paid out of the sale, and the deed can be signed at the office or wherever you are, before a notary.
Behind on the mortgage? A sale can still close before a sheriff's auction, and if you live in the home you have ten business days after signing to cancel; our foreclosure guide covers the timeline. The state flood risk disclosure is part of every New Jersey sale, and nothing on it rules out an offer from us. North Brunswick sits in Middlesex County, where all 25 municipalities are in our service area; nearby, we also buy in New Brunswick and South Brunswick.
For an estate, the letters a personal representative needs come from the Middlesex County Surrogate (phone 732-745-3055), whose office is in the county building on Bayard Street; our inherited house guide walks through the rest. Central Jersey Legal Services handles Middlesex County intake at (732) 249-7600 for owners and tenants who qualify, and older owners can ask the county's aging and disability office, upstairs in that same building, for guidance at 732-745-3295.
