Irvington, NJ Fire Regulations: Smoke Detectors (2026)

Under § 355-15B of the Township Code, no owner of a covered residential property may rent, lease or otherwise deliver up a dwelling unit for occupancy until the Director of the Department of Housing Services, or a designee, has issued a temporary or permanent certificate of habitability. To get one, the property must pass inspection by a code enforcement officer. Section 355-15F defines a 'substantial violation,' the category of defect that blocks that certificate, as anything that renders a dwelling unit hazardous to health or safety, and it lists 'lack of smoke detectors' by name alongside exposed or deteriorated electrical wiring, inoperable plumbing, lack of a second means of egress, lack of security locks, and severely cracked ceilings.

An owner must apply for the certificate at least five business days before a unit is due to be occupied, and pay $98 per dwelling unit ($47 for a reinspection). If an inspection turns up a substantial violation such as missing smoke detectors after occupancy has already begun, the Director issues only a temporary certificate, conditioned on the owner fixing the problem within 15 days. Separately, anyone installing or replacing a smoke detector itself needs an electrical construction permit from the Township's Construction Code Agency; the flat fee for a one- or two-family dwelling is $50 under § 240-3E(g).
