Key considerations for North York
Toronto allows one secondary suite inside the home and one detached garden or laneway suite per lot.
ADU feasibility depends on lot size, coverage, setbacks, and lane access availability.
Minor variance applications are sometimes needed when lot constraints prevent full as-of-right compliance.
Construction costs, permit fees, and development charges (where applicable) vary by municipality and unit type.
