Wayne, NJ Building Setbacks & Zoning: Lot Coverage Limits (2026)

Wayne Township Code § 134-32.2 H, amended 6-19-2013 by Ord. No. 22-2013, sets maximum impervious coverage in the R-45 very low density residential district at 40%. Subsection I adds a second cap for the front yard: impervious coverage area within the required front yard shall not exceed 35% of the total front yard area. For lots with more than one front yard, the total front yard areas shall not be combined for the purposes of calculating this provision, so a corner lot is tested separately on each street frontage.

What counts is set by the definition in § 134-2.2. Impervious coverage is the percentage of the plot or lot area covered by all impervious surfaces, including buildings and structures, parking areas, driveways, tennis courts, patios, decks, pools, walkways and retention and detention basins. Surfaces such as laid stones, slate or timber laid directly on the ground with open joints constitute 50% of impervious surface coverage. Surfaces such as gravel, loose stones, special paver stones with voids for grass, and timber decks with open joints constitute 25%.

Other limits sit alongside the 40% figure. Section 134-62.1 G caps the total lot coverage of all accessory buildings on a single-family lot at seven percent of the total lot area or 1,000 square feet, whichever is less, and § 134-62.1 F caps an accessory garage at 700 square feet. Section 134-62.1 B bars gravel driveways on new dwellings and requires asphalt, paving stone, brick paver, concrete or a similar surface. Residential driveways must stay a minimum of three feet from the side property lines.

The Residential B Cluster district uses a different formula in § 134-36.2 B(1)(c): 35% or 4,000 square feet, with deck areas included. A zoning permit from the Zoning Officer is required before building (§ 134-26.3 B).
