Before You Build in Union City, NJ: Permit & Rule Checklist (2026)

Fence permits are required in Union City under Chapter 223 (Land Development Ordinance) and NJ UCC. A zoning permit must accompany the building permit application. Applications are processed by the Zoning Officer at Union City City Hall.

Union City fence height limits are governed by Chapter 223 (Land Development Ordinance, amended 2019). General residential limits follow NJ standards: front yard fences typically 3–4 feet maximum; rear and side yard fences up to 6 feet. Contact Union City Zoning Officer for district-specific limits.

New Jersey law requires the finished side of a fence to face neighboring properties. Union City's Land Development Ordinance requires notification to adjacent owners and a property survey before fence installation. Shared boundary disputes are handled by Union City Municipal Court.

Swimming pools in Union City must comply with N.J.A.C. 5:23 (NJ UCC) requiring a minimum 4-foot fence with self-closing, self-latching gate around all pools deeper than 24 inches. Given Union City's micro-lot sizes, in-ground pools are rare but must meet these standards.

All pool installations in Union City require building permits under Chapter 426. NJ UCC (N.J.A.C. 5:23) electrical safety, barrier, and inspection requirements apply. Given Union City's extreme density, pool safety compliance is critical.

Above-ground pools in Union City require permits if deeper than 24 inches under N.J.A.C. 5:23. NJ barrier requirements apply. Given Union City's extremely small lot sizes, above-ground pools are largely impractical.

Garage conversions in Union City require building permits and zoning approval under Chapter 223 and Chapter 426. Conversions to ADUs are covered by the 2024 NJ ADU mandate. Certificate of Occupancy required before occupying converted space.

Union City allows ADUs under the 2024 NJ ADU mandate (N.J.S.A. 52:27D-123.16, effective 2025) and Chapter 223 (LDO). ADUs are permitted by right on lots with single or two-family homes. Chapter 223 provides local ADU implementation standards including building permits and Certificate of Occupancy.

Carports in Union City are regulated as accessory structures under Chapter 223 (Land Development), originally adopted Nov. 4, 2019, and the New Jersey Uniform Construction Code (N.J.A.C. 5:23). Permitted accessory buildings must have a building footprint of less than 1,000 square feet and may not be placed where not allowed by the underlying zoning district; a zoning permit and a UCC building permit are required. Given Union City's extreme density and tiny lot sizes - among the highest densities in the United States - free-standing carports are very rarely feasible.

Sheds in Union City require zoning and building permits under Chapter 223 (LDO) and Chapter 426. Given Union City's extremely small lot sizes, sheds are rarely feasible. Sheds must comply with setback requirements and may not be placed in front yards.

Fire pits are impractical to the point of prohibition in Union City. NJ UCC setback requirements (15–25 feet from structures) cannot be met in Union City's micro-lot urban environment. The Fire Department must be consulted for any outdoor fire installation.

Outdoor burning is effectively prohibited in Union City. NJ Uniform Fire Code (N.J.A.C. 5:70) bans open burning for waste disposal. Union City's extreme urban density makes any outdoor burning impractical and dangerous.

Union City regulates trimming of trees in the public right-of-way under Chapter 223 and applicable tree ordinances. Street tree trimming requires a permit. Private trees on private property may be trimmed without a city permit.

Union City water is supplied by Jersey City Municipal Utilities Authority (MUA) and United Water/Suez. NJDEP drought declarations may trigger mandatory restrictions on lawn watering and other outdoor water use. No permanent restrictions under normal conditions.

Removing street trees or trees in Union City's public right-of-way requires a permit from the city. Private tree removal on private property generally has fewer requirements. Construction projects must address any tree impacts in permit applications.
