Summary
Naperville requires owners of vacant residential lots to grade for drainage and establish turf within one year of nearby build-out, or 30 days after a razing, and bans standing water and debris at all times.
RESIDENTIAL VACANT LOT: Any residentially zoned lot absent an occupancy permit issued by the City of Naperville... At no time shall standing water, trash, litter, compost, carcasses, broken concrete, broken asphalt, other debris, or other items that result in the degradation of the property or surrounding properties be located on any vacant lot.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 101).
Full Breakdown
Under § 5-1H-4, a residential vacant lot is any residentially zoned lot without a City occupancy permit. Once 100% of adjoining lots or 90% of a subdivision phase is occupied, but no sooner than five years after final plat approval, the owner has one year to grade the lot for positive drainage and establish turf; a lot created by razing a structure gets just 30 days unless a building permit is active and construction has started. Standing water, trash, litter, compost, carcasses, and broken concrete or asphalt are prohibited at all times, and sidewalks must be installed under § 5-2B-5.
Violations & Fines
A vacant lot left ungraded, without turf, or holding standing water or debris violates § 5-1H-4; owners may seek a variance from the Building Review Board under § 2-4-4, but the duty is retroactive to lots that existed at adoption.
