BASEMENT APARTMENT & SECONDARY SUITE QUESTIONS

Answers to common basement permit questions.

Does a basement apartment or secondary suite require a building permit? Creating a new unit or legalizing an existing one commonly involves building-permit and zoning requirements. The exact requirements depend on the property, existing conditions and municipality.

What drawings are commonly required for a basement apartment permit? The scope commonly includes existing and proposed floor plans, elevations, sections, construction details and information about exits, fire separations and building systems. The municipality determines the final requirements for each application.

Can an existing basement apartment be legalized? Potentially. Start with the property address, existing conditions and any municipal records or notices. Permit Works can review the available information and identify the likely drawings and consultant coordination needed.

Can every property support a basement apartment or secondary suite? Not necessarily. Eligibility depends on zoning, building type, existing conditions and other property-specific requirements. A property review should come before drawing work.

What should I send for a basement permit quote? Send the property address, describe whether the unit is new or existing, and attach any survey, plans, photos or municipal notice you already have.
