Freehold Township by the numbers

The U.S. Census ACS 2020-2024 5-year estimates count 35,651 residents in Freehold Township, with a median home built in 1984. About 84 percent of homes are owner-occupied and 62 percent are single-family detached. Heating splits as follows: 83 percent utility gas, 1 percent bottled gas (propane), and 4 percent fuel oil.

The lower detached share means a good number of township homes are attached or multi-unit. A detached house can usually take a standby unit on a pad beside the house. In an attached community with shared walls, the placement options are narrower, and an association may have its own rules, so check with the association as well as the township.

With 83 percent of homes on utility gas, natural gas is the starting assumption for most township houses. The 4 percent on fuel oil and the 1 percent on propane are the homes where a different fuel plan is needed.

Freehold Borough is a different kind of place

The census numbers for Freehold Borough are different enough to deserve their own paragraph. The borough has 12,507 residents and a median home built in 1960, according to the same ACS 2020-2024 5-year estimates. Only about 54 percent of homes are owner-occupied, and 54 percent are single-family detached. About 76 percent heat with utility gas, 4 percent with bottled gas (propane), and 4 percent with fuel oil.

A median build year of 1960 may mean older wiring and panels, and with an owner-occupancy rate of 54 percent, close to half of homes are renter-occupied. A landlord who wants backup power for a small multi-unit building faces a different calculation than a homeowner, and a tenant should not assume that a generator can be installed without the owner's approval.

Smaller lots tighten placement. A unit has to sit at least 5 feet from windows, doors, and openings, and that can rule out much of the side yard on a narrow property. The site plan comes first, and the equipment follows from it.

Two construction offices, two applications

Freehold Township's Construction Department is at 1 Municipal Plaza, Freehold 07728. Its generator permit list includes building, electrical, plumbing, and fire subcode forms, plus a zoning application. That is more forms than many homeowners expect for one machine, because a generator touches wiring, fuel piping, and the building itself.

Freehold Borough's Building & Construction Office is at 30 Mechanic Street, Freehold 07728. It is a separate office from the township's, with its own staff, process, and local rules. A project in the borough is filed with the borough, and a project in the township is filed with the township. Neither office handles the other's permits.

The state code requires a permit before work starts, and a home standby generator has to be sized to a load calculation or use automatic load management. Bring the calculation, a one-line diagram, and the spec sheets for the generator and transfer switch. Gas piping typically needs a riser diagram and a pressure test.

Isaias and what it meant for Freehold

On August 4, 2020, Tropical Storm Isaias put about 701,018 JCP&L customers in the dark at the peak. Statewide, the most damage was in Monmouth, Morris, and Union counties, and full restoration came about August 11, according to the NJ BPU staff report of November 2020.

That is county context, not a Freehold-specific measurement, and it is the right way to describe it. Freehold is in Monmouth County, and a storm of that size reached the county broadly. For a homeowner it is a reason to plan for a multi-day outage rather than a short one.

Natural gas, propane, and getting the fuel right

Natural gas here comes from New Jersey Natural Gas, which wants its generator inquiry form submitted before a gas generator is bought. Pressure, meter capacity, and run length from the meter all feed into that inquiry.

For a house without gas service, propane is the alternative. For an existing one- or two-family home, a new LP vapor installation under 2,001 gallons water capacity falls under the local Mechanical Subcode, per DCA Bulletin 09-1 as revised in July 2026, citing N.J.A.C. 5:23-3.4(d). The local office has jurisdiction for containers of 2,000 gallons aggregate or less. Tank size sets runtime, so it is worth deciding with the load calculation in hand.

As a general sizing example, a well pump has a startup surge above its running load. Whether a particular house has a well is a question for the house, and the calculation should be built from what is actually there.

Cost, maintenance, and a safe connection

Generac's air-cooled home standby line runs from 10 to 28 kW, and the company says permits, gas, and site preparation take weeks while the installation itself takes hours. HomeGuide puts annual maintenance at $200 to $650. Those are published national ranges, not a quote from us.

A free on-site assessment with a written load calculation gives a number for a specific house, in either Freehold.

Questions to settle before a Freehold project starts

Four questions cover most of the planning. Which municipality is the house in, the township or the borough? Is the fuel natural gas or propane? What is the written load calculation, and does it count the largest motors? Where on the lot can the unit sit while staying clear of windows, doors, and openings?

Answering those first makes the permit applications straightforward, whether they go to 1 Municipal Plaza or 30 Mechanic Street. It also keeps the estimate honest, because the gas run, the pad, and the transfer switch are priced from facts about the house instead of assumptions.
