New Jersey Homebuilding Since 1990
Single-family building permits issued in New Jersey each year, from 35 years of U.S. Census Bureau records.
New Jersey homebuilding peaked in 1998 at 25,459 single-family permits, fell 75% to a low of 6,475 in 2011, and reached 12,820 in 2025 — about 50% of the peak. Sustained low permit volume tends to mean fewer active builders competing for work, which can affect both pricing and how long you wait for a contractor.
That volume ranks New Jersey 21st of 51 U.S. jurisdictions for single-family permits issued in 2025. See how all 51 states compare on recovery, cost, wages, and land →

Regional Overview
Building in New Jersey: Codes, Permits & Licensing
What to expect when permitting, designing, and licensing a build in New Jersey.
Median construction-trades pay in New Jersey is $35.32/hour, with carpenters at $30.77, electricians at $37.14, and plumbers at $37.61 — U.S. Bureau of Labor Statistics OEWS, May 2025.
Permit Process
New Jersey permitting runs through the municipality under the statewide New Jersey Uniform Construction Code, which applies consistently across the state's many local building departments. Coastal Shore towns typically add flood-zone review given hurricane and nor'easter exposure.
Codes & Requirements
New Jersey maintains a uniform statewide code with meaningful energy provisions, and coastal counties add elevated-foundation and flood-vent requirements in FEMA-designated flood zones, particularly along the Jersey Shore. Frost-depth foundation rules apply statewide given the state's real winters.

Climate Impact
New Jersey's humid subtropical-to-continental climate supports basement construction as common practice across most of the state, with coastal areas sometimes favoring elevated or crawlspace foundations for flood resilience instead. HVAC systems handle both a genuine heating season and humid summer cooling.
New Jersey averages 4,850 heating degree days and 992 cooling degree days a year, so heating drives the mechanical load. Combined, that is the 26th-highest heating-and-cooling demand of the 48 contiguous states — a direct input to how much HVAC capacity and insulation a build here needs. — NOAA Climate at a Glance, 2016-2025 average, base 65°F.

About Construction Costs in New Jersey (2026)
Based on our index of 876,000+ real building permits and the NAHB Cost of Constructing a Home study, building a new home in New Jersey costs an average of $247 per square foot for mid-range construction. A two-story design runs a little under that per square foot, putting a typical 2,000 sq ft two-story home at approximately $471,504 before land. New Jersey runs about 32% above the national average, primarily due to higher labor costs (labor index: 1.35×).
The range from basic ($348,612) to premium ($642,048) reflects the significant impact of finish quality. According to NAHB data, interior finishes alone account for 16–21% of total construction cost. Basic homes use builder-grade materials — laminate countertops, vinyl flooring, stock cabinetry — while premium homes feature custom cabinetry, stone countertops, high-end mechanical systems, and designer-level finishes.
Key local factors in New Jersey include the humid subtropical climate (affecting insulation requirements, foundation depth, and HVAC specifications per BLS regional construction indexes), a labor index of 1.35× the national average, and typical permitting costs of $5,500.
Note: all figures cover construction costs only — land is excluded. Land prices in New Jersey range from tens of thousands in rural areas to hundreds of thousands per lot in Newark and other major markets. As a reference point, FHFA research data (2015 (base-year-standardized pooled cross-section estimate, sample pooled across 2012-2022)) estimated average residential land value in New Jersey at roughly $666,100 per acre, with land typically representing about 41.6% of total property value — a useful order-of-magnitude gauge, not a current market quote (see methodology).
