Legal Basements & Secondary Suites

Renovation work intended to meet applicable Ontario Building Code and municipal requirements — with the design, drawings and permit coordination handled under one accountable contractor.

For homeowners and investors, a properly planned legal basement can add meaningful usable space — and, where permitted, an opportunity for rental income. Compire Construction & Renovation helps coordinate the full scope of work: basement layout planning, drafting, permit coordination, side entrances, egress window openings, fire separation, plumbing and electrical rough-ins, insulation, drywall and finishing.

We work with appropriate qualified professionals — designers, engineers and licensed trades where the project requires — and we coordinate the municipal permit and inspection process on your behalf. Every property and municipality is different, so we scope each project individually rather than applying a one-size-fits-all template.

Permit approval, zoning requirements and secondary-suite eligibility vary by municipality and property. Applicable work must be completed and/or reviewed by properly qualified or licensed professionals where required.
