What is the Type B Inspection process in a Multi-Dwelling Structure (3 units or more)

In multi-dwelling structures, the bedrooms to be rented to overnight guests must also have a smoke detector that is interconnected with a smoke detector in an adjacent hallway and be located on a floor of a dwelling unit equipped with a functioning carbon monoxide alarm. Interconnected smoke detectors may be hardwired or may function wirelessly. As part of the Conditional Use land use review process the property owner or their authorized agent must verify through self certification that the bedrooms meet these requirements. If you do not currently have hardwired interconnected smoke detectors in your dwelling unit (a requirement for newly constructed units) you may wish to work with the property owner to install battery operated wireless interconnectable smoke detectors. These devices are readily available at home improvement stores and the devices should be installed according to the manufacturer’s instructions. Battery operated or plug in carbon monoxide alarms are also readily available at home improvement stores and the devices should be installed according to the manufacturer’s instructions.

There are also additional requirements for Type B Accessory Short-Term Rentals that are proposed in building subject to Chapter 13 of the Uniform Building Code. To learn more about these requirements, please see Are Accessory Short term rentals allowed in multi-dwelling structures subject to Chapter 13 of the Uniform Building Code?
