Once a building permit is issued construction will need to begin within six months from the date of issuance. Construction cannot be suspended for a period of more than six months, and must be completed within a period of three years. If these conditions are not met, the permit will expire.
For a project on which construction has been ongoing, the property owner may renew a permit, prior to expiry, for an extended period of up to 12 months. Only one renewal is permitted. The completion of additional forms and fees may be required.
