Renting in Saint John
Saint John’s Minimum Property Standards Program inspects rented residential apartments for health, safety and comfort. Minimum standards and vacant building concerns are reported to the City through online complaint forms, and the One Stop Development Shop handles them. The City’s housing catalogue page also describes garden suites and multi-unit limits by area.
Use the minimum standards program
The City describes the program as inspecting rented residential apartments to ensure they meet minimum requirements for health, safety and comfort, under New Brunswick Regulation 84-86. Owners complete a submission package and send it to the One-Stop Development Shop at City Hall or by email. Ask the City if you are unsure whether a unit needs to be submitted. Keep a copy of the package and the date you sent it.
Know how complaints and vacant buildings are handled
The City accepts online minimum standards complaints about safety concerns in rental properties and does not accept anonymous complaints. A separate vacant building form covers unoccupied buildings that have become a hazard to public safety. If a property of yours sits empty between tenancies, note its condition and the dates you inspected it. A City team member follows up with the person who submitted a complaint.
Check the lot before adding a suite
The City’s housing design catalogue says garden suites have been permitted on most lots since 2014, with exceptions when zoning requirements cannot be met. It also states that lots in the Primary Development Area allow up to four residential units, subject to setback, lot size and parking requirements. Every lot differs, so confirm yours with the City before advertising a new unit. Save the written answer in your property file.
