Summary

Section 162-11(D) of the Monroe Township Code in Gloucester County, New Jersey, requires each dwelling unit going through a certificate of occupancy inspection to have at least one smoke detector and one carbon monoxide detector, approved, listed and labeled, installed consistent with its listing.

§ 162-11. Inspections of dwelling units and certificates of occupancy. ... D. Smoke detectors and carbon monoxide detectors required. In addition to the requirements for a certificate of occupancy hereinabove set forth, it shall also be required that each such dwelling unit have installed therein a minimum of one smoke detector and one carbon monoxide detector approved, listed and labeled "smoke detector" and "carbon monoxide detector," sensing visible or invisible particles of combustion, installed in a manner and location consistent with its listing. When activated, the detector(s) shall provide an alarm suitable to warn the occupants within the building.

Full Breakdown

Section 162-11(D) of the Monroe Township Code adds a detector requirement on top of the certificate of occupancy inspection. Each such dwelling unit must have installed in it a minimum of one smoke detector and one carbon monoxide detector. The devices must be approved, listed and labeled as a "smoke detector" and a "carbon monoxide detector," they must sense visible or invisible particles of combustion, and they must be installed in a manner and location consistent with the listing. When activated, the detector or detectors must provide an alarm suitable to warn the occupants within the building.

The rule rides on the certificate of occupancy process in § 162-11. Subsection A(1) requires a certificate of occupancy for human habitation of all existing dwelling units in the Township of Monroe before a change in occupancy of any unit, and subsection A(2) requires all rental units to be inspected annually to retain their certificate of occupancy. The Housing Official and/or Code Enforcement Officer has 10 working days from a fully completed application and fee to make the required inspections, and § 162-11(G) makes compliance with subsection D a condition of issuing the certificate.

If the unit fails, the official notifies the applicant in writing within the same 10 working days and specifies each violation. The applicant then notifies the Housing Officer and/or Code Enforcement Officer in writing and submits a reinspection fee of $25, and reinspection follows within five working days of receiving the notice and fee. That cycle repeats until every violation is corrected and the certificate issues.

Two neighboring rules support the same safety goal. Section 162-26(G) requires each rental facility to contain a fire extinguisher on every floor or portion used as a rental facility, kept in a designated location where it can operate without delay. Section 162-11(P) adopts the most recent New Jersey State Housing Code, the International Fire Code, the International Property Maintenance Code and Chapter 162 as performance standards.

Violations & Fines

A missing detector blocks the certificate of occupancy until corrected. Violating Chapter 162 is punishable under § 162-30 by a fine of not to exceed $1,000, up to 90 days in the county jail, or both, and each day is a separate offense. Under § 162-19, the inspecting officer's notice gives 10 days to correct before the certificate can be revoked and occupancy prohibited.
