Edison FAQ
What is Edison's lot coverage limit?
It depends on your zoning district under Chapter 37. Each district sets a maximum building coverage in the bulk schedule. Accessory structures in residential zones are further capped at 10% of the lot or 35% of the rear yard, whichever is less, under §37-48.
Does a new patio or driveway count toward coverage in Edison?
Impervious paving such as driveways and patios counts toward impervious coverage limits where the zone applies one, and may trigger NJ DEP stormwater rules (N.J.A.C. 7:8) if the project adds more than 0.25 acre of impervious surface. Smaller residential projects may still need local stormwater review.
Who checks lot coverage in Edison?
The Edison Construction Department reviews the plot plan at building-permit application and confirms compliance with Chapter 37 bulk standards before issuing the permit. Final inspection verifies that built coverage matches the approved plot plan.
