Lawrenceville is the historic village at the center of Lawrence Township in Mercer County, and most people use the two names interchangeably. The Lawrence Historical Society records that the township was formed in 1697 as Maidenhead and renamed Lawrence on January 24, 1816, for Captain James Lawrence, a naval hero of the War of 1812. The Academy of Maidenhead, founded in 1810, is today's Lawrenceville School. Most of the township is in the 08648 ZIP code, and its northern part falls in 08540.
The village is one of New Jersey's earliest protected streetscapes. The Lawrence Township Historic District was listed on the National Register in 1972, covering Lawrenceville and the land to its north on both sides of Route 206, with Colonial, Federal and mid-nineteenth-century revival buildings, and the historical society notes it was one of the first registered historic districts in the state. Many of the houses of Maidenhead's early settlers still stand in the village. The township has a Historic Preservation Committee that reviews applications affecting landmarks and districts, so if your house is in the district, ask the township whether your exterior work needs to go before it.
Away from the village, Lawrence Township is mostly later housing. Averaged over 2020 to 2024, the Census Bureau's American Community Survey counts about 12,900 homes in the township; the 1980s were the busiest decade, with 23 percent of them, and about half, 51 percent, were built before 1980. In the Lawrenceville area itself, the survey puts 61 percent of homes in the 1980s alongside the much older village houses. If your home is in a townhome or condominium association, check its rules on exterior colors and scheduling first.
On the older houses in and around the village, exterior painting starts with real prep: scraping failing paint, spot-priming bare wood and pointing out soft sills and trim before color goes on, with breathable primers on old clapboard. Inside, original trim gets a bonding primer over old oil paint. Those older houses also bring in the federal lead rule. On a house built before 1978, scraping or sanding more than six square feet of paint in a room, or twenty square feet on the outside, is paid work the EPA's Renovation, Repair and Painting rule reserves for certified firms. NJ Painting Co. is not EPA Lead-Safe Certified, so where a house needs that, the work has to go to a certified contractor, and our estimate will say so plainly.
In the 1980s neighborhoods, the requests run toward cabinet refinishing, whole-home interior repaints and the first proper repaint of builder trim. We use Benjamin Moore and Sherwin-Williams products chosen for the surface, and every estimate in Lawrence Township is free and written.
