A building permit is required prior to alterations made to the interior of an existing building. Alterations may include but are not limited to:
- Interior partitioning
- Adding usable floor area i.e.) mezzanine or second story
- Installing a new roof top unit (HVAC)
- Replacement or removal of a structural component
- Reconstruction due to damage from fire, flood or other cause
- Replacement of guardrails
- Any work involving fire separations
- Installation of a spray booth
When applying for permits to construct interior alterations within an existing commercial building, the following information must be submitted to process your application:
Three (3) complete sets of working (construction) drawings with all related details including:
- Key plan showing the entire building, the tenant location and adjacent tenants (if the building has more than one tenant)
- Description of the building including number of stories, building area (in square meters), construction type such as wood frame or masonry block.
- Floor plans showing all involved floor levels, clearly describing what is existing and any new revisions (Note: The floor plans must show all room uses, corridors, exits, elevators, etc.)
- All applicable architectural, structural, plumbing, heating, sprinkler and electrical changes.
- Existing building services such as sprinkler and fire alarm systems.
- The drawings must include dimension or be scaled, i.e. 1/8” = 1.0”.
- All of the work must be shown regardless of who is doing the work.
- A Site Plan may be required depending on the extent of the work.
- Barrier-Free access must be considered when making alterations to a building. The Barrier-Free Design Guide is available from the Safety Codes Council website by clicking here.
To provide an accurate review of your submittal, the information on your drawings should be detailed enough that any contractor could take those drawings and construct what is proposed.
A complete submission will enable a prompt review and processing of your permit.
