NJ UNIFORM CONSTRUCTION CODE · ASCE 7-16 / 7-22 · JERSEY SHORE
New Jersey Wind Load Requirements
Coastal and inland wind design under the NJ Uniform Construction Code — from the Jersey Shore high-wind belt to inland exposure, with solar-ready ASCE 7 provisions.
ADOPTED CODE · UCC
The Uniform Construction Code
New Jersey adopts the UCC statewide, administered by the Department of Community Affairs, referencing the IBC/IRC with state amendments and ASCE 7 for wind.

IFC 2021Basic vs Ultimate Wind Speed
What was formerly "Basic Wind Speed" is now the Ultimate Wind Speed used directly with LRFD. For ASD, reduction factors bring higher ultimate pressures back to outcomes consistent with prior methodology. Values are nominal design 3-second gust speeds at 33 ft above ground, Exposure C.
WIND ZONES · COAST VS INLAND
Jersey Shore High-Wind, Inland Lower
The DCA provides guidance on each municipality's orientation to the 100 mph wind speed line. Coastal exposure runs higher; inland values step down away from the shore.
Coastal — Jersey Shore
Higher wind speeds; within 1 mile of the coast carries the strongest exposure and debris triggers.
105–120 MPH RANGEInland — Away from Shore
Wind speeds step down west of the shore; recent maps shifted higher speeds farther offshore.
LOWER THAN COASTRisk Category × Coastal Wind Speed
| Risk Category | Description | Coastal Wind Speed |
|---|---|---|
| Category I | Low life/safety hazard | 105 mph contour shifted west |
| Category II | Residential, offices | Unchanged from previous maps |
| Category III | Schools, assisted living | Lower values than previous |
| Category IV | Essential facilities | Higher values than Cat III |
Windborne Debris Regions
Debris regions are areas within 1 mile of the coastal mean high water line where ultimate design wind speed is ≥ 130 mph, or any area where ultimate design wind speed is ≥ 140 mph. Updated maps moved higher speeds farther offshore, reducing debris-region requirements for many NJ coastal municipalities.

SOLAR PV · UCC BUILDING SUBCODE
Rooftop Solar Structural Requirements
Roof structures supporting PV must resist each governing condition under the UCC Building Subcode and ASCE 7.
Combined Loads
Uniform and concentrated roof loads with the PV system dead loads.
UCCWind Design
Per IBC Section 1609 wind provisions and ASCE 7.
§ 1609Seismic Design
Per IBC Section 1613 earthquake provisions.
§ 1613ASCE 7 Solar Panel Provisions
| Section | Application | Key Points |
|---|---|---|
| 29.4.3 | Low-slope roofs (≤ 7°) | Buildings of all heights with flat roofs |
| 29.4.4 | Parallel to roof surface | Gable or hip roofs with slopes < 7° |
| 29.4.5 | Ground-mount (ASCE 7-22) | Fixed-tilt systems |
Fire Code — NJ UCC Fire Subcode (2021 IFC, Chapter 12)
PV systems install per IBC/IRC as applicable; electrical portions comply with NFPA 70 (NEC); rooftop systems comply with Sections 1205.2 through 1205.4.3, including access and pathways for firefighter access.
RISK CATEGORIES · ASCE 7
How Risk Category Sets the Map
Higher risk categories read a longer-return-period wind speed map — higher design speed, higher loads. There is no fixed multiplier between categories.
Category I
Low life/safety hazard — 300-yr map.
LOWESTCategory II
Homes, offices — 700-yr standard map.
STANDARDCategory III
Schools, assisted living — 1,700-yr map.
SUBSTANTIALCategory IV
Essential facilities — 3,000-yr map.
HIGHESTPost-Sandy Resilience
After Hurricane Sandy struck the NJ coast in October 2012 — over $30 billion in damage — codes strengthened: elevated construction in flood zones, enhanced coastal wind resistance, continuous load paths from roof to foundation, and utility resilience standards including solar.
PERMITTING · PE SEAL
No Mandatory Wind Load Permit
New Jersey is one of 40 states where building departments do not require PE-sealed wind load calculations by law. Calculations may still be needed for insurance, manufacturer warranties, or engineering best practice — especially for coastal properties.
