Selling in Clark Township
Clark sits in the southern corner of Union County, a township of about 16,400 people on a little over four square miles. It is a place where people stay. Owners occupy more than three homes in four, and more than one resident in five is 65 or over. Where a Clark house is still owned by the people who bought it decades ago, the sale often involves original kitchens, older roofs and heating systems, and a seller who would rather not manage a renovation before moving.

A median value of roughly $610,000 is a starting point, not a price. We look at what sold nearby, what the house needs, and how much time you want, and the figure we write down reflects all three.
Clark's Certificate of Resale
Before a residential, industrial or commercial property in Clark is sold, the township requires a Certificate of Resale. It is handled by the Construction Department, which can be reached at 732-428-8401 on weekdays from 8:30 to 4, and both the application and the fee are taken online. Homes have a second piece: the Smoke Detector Inspection form, also paid online, which covers the smoke and carbon monoxide alarm check New Jersey requires before a one- or two-family house is sold.
Two details shape the timing. First, a Certificate of Resale stays valid for 180 days from the day it is issued, so a sale that drags past six months may need a fresh one. Second, the department's inspectors work on Tuesdays and Thursdays, arriving at some point in a window that runs from 10 in the morning to 4 in the afternoon, and they will not promise an exact hour. For a seller who is still living in the house, or who has moved away and has to arrange access, that window matters.
When we are the buyer, the application, the access and the inspection day are ours to manage. If the inspector writes up something that needs correcting, such as missing alarms, a handrail or an unfinished permit, the correction is our cost, because we priced the house knowing it might come up. You do not need to fix anything before you accept our figure.
Tax Bills, Due Dates and the Bill You Hand Over
Clark mails its annual tax bills in July, and payment is due in four quarters: Feb. 1, May 1, Aug. 1 and Nov. 1. Payment must reach the tax office by the last day of a ten-day grace period, which slides to the next business day when it ends on a weekend or holiday; postmarks do not count. Late amounts carry 8% interest on the first $1,500 and 18% on anything above, and if unpaid taxes, sewer charges and interest reach $10,000 by the end of the year, a 6% penalty is added. The office notes that the collector has no power to forgive interest.
One local habit is worth knowing. When a property is sold, Clark asks the seller to give the tax bill to the buyer, because a new set of bills is not mailed when ownership changes. On a sale to us the title company works from the township's payoff figures, splits the current quarter by the day, and pays any arrears from the price, so nothing is left hanging on your name. In 2025 Clark's general tax rate was 2.269 and its effective rate 1.899, one of the lower effective rates in the county.
The Sewer Utility Bill
Clark runs its own sewer utility, and its charge is tied to water use. Homes pay a minimum of $280 for the first 100,000 gallons. To keep lawn and pool season from inflating the bill, the township takes the water used from November through April and doubles it to estimate the year, then charges 2.5 cents a gallon above 100,000. Bills go out once a year in February with two payment stubs, due March 15 and September 15. Any unpaid half is part of the payoff at closing, and final water readings come from the water company that serves the house.
Rentals, Vacancies and Estates
Clark landlords register every rental unit with the township each year. Units built before 1978 also need a lead-based paint inspection by a private firm; a passing unit receives a Lead-Safe Certificate good for three years, and it gets uploaded with the registration. Owners must carry liability insurance, generally $500,000 or more, or $300,000 where the owner lives in a building of up to four units, and file the certificate yearly. If your rental is behind on any of this, the sale can still go ahead: the tenants stay, their leases and deposits carry over to us, and we bring the registration current. Our page on selling a rental in New Jersey walks through it.
An empty house carries its own duty. Under Clark's Ordinance 23-07, an owner must register a property with the Township Clerk within 30 calendar days of it becoming vacant or abandoned, including after foreclosure, and renew the registration every year it stays empty. Families handling an estate often miss this while waiting on probate. The Union County Surrogate issues the letters an executor needs to sell, at the courthouse in Elizabeth or by appointment in Westfield, and children and grandchildren owe no inheritance tax. Our inherited house guide explains the order of steps.

Foreclosure Timing
A Clark house in foreclosure is auctioned by the Union County Sheriff, usually at 2 PM on a Wednesday at the Warinanco ice rink in Roselle. You can sell any time before that sale. If you sign with us while in foreclosure, state law gives you ten business days to cancel, so we build that period into the closing date. The full process is on our New Jersey foreclosure page.
