Homes and electricians in Trenton: the local numbers
Housing in Trenton
- Trenton has about 34,513 homes (housing units).
- The typical (median) home was built in 1953, 17 years older than the New Jersey median of 1970.
- 79% of homes were built before 1980 and 60% before 1960; 5% were built in 2010 or later.
- The median value of an owner-occupied home is $160,700.
- 38% of occupied homes are owner-occupied and 62% are rented.
- 16% of homes are single-family detached houses.
- The most common heating fuel is natural gas from a utility (64% of homes), followed by electricity (26%).
- The median home has 5.1 rooms.
- Median gross rent is $1,294 a month.
- That makes Trenton's housing among the older stock in the country: the typical U.S. home was built in 1980.
- Home values run 65% below the New Jersey median of $454,400.
- Most occupied homes here are rented (62%), so tenants should get their landlord's approval before hiring anyone for repairs or alterations.
- Apartments, condos and attached homes make up most of the housing: only 16% of homes are detached houses, so many jobs involve building rules, shared walls or a condo board.
60% of Trenton's homes were built before 1960. Homes of that age may still have knob-and-tube or ungrounded two-prong wiring and service panels too small for modern loads such as EV chargers and heat pumps, so a panel and wiring check is worth doing before adding circuits.
Gas heat is the norm in Trenton (64% of homes), so switching to an electric heat pump usually starts with checking whether the panel has room for new 240-volt circuits.

Who regulates this trade
New Jersey Board of Examiners of Electrical Contractors
Verify a licence on the official register →Insurance and workers' compensation
$500,000 per occurrence general liability minimum for home improvement contractors registered with the state. Workers' compensation is mandatory for all employers.
Mechanic's lien protection
New Jersey mechanics liens must be filed within 120 days after the last day of work or delivery of materials. The lien remains valid for 2 years from filing but must be enforced through a court action within that period. Unlike many states, New Jersey does not require a preliminary notice, but the lien must be notarized and include a property description verified by the county clerk.
What catches homeowners out in New Jersey
New Jersey requires all home improvement contractors to register with the Division of Consumer Affairs — this is separate from trade-specific licensing. However, plumbing, electrical, and HVAC work require additional trade licenses from the appropriate boards. The state's Consumer Fraud Act provides strong protections for homeowners, allowing you to sue for triple damages if a contractor engages in fraudulent practices. Always verify registration at the NJ Consumer Affairs website before signing a contract.
