Mechanical Permit

Mechanical Permits ensure that projects comply with the minimum standards that help safeguard life or limb, public health, property and welfare. No part of heating, ventilating, air conditioning or refrigeration systems shall be installed, altered, replaced or repaired unless a Mechanical Permit has been obtained for the work.

Based on your desired scope of work, a mechanical permit may be a Simple "No-Plan" Mechanical Permit or a Plan (required) Mechanical Permit. See Information Bulletin 103 to determine whether the scope of work qualifies for a Simple “No-Plan” Mechanical Permit.

Simple "No-Plan" Mechanical Permit

Homeowners, property owners and licensed contractors can obtain a Simple No-plan Mechanical Permit for minor installations for all non-historically or potentially designated properties only, including:

  • Installations of forced-air units (FAU) or air conditioner units (A/C)
  • Installations of exhaust fans
  • Replacement of furnaces
