Apply for Your Building Permit Before You Build
Whether you're building something new or making improvements to an existing property, a building permit may be required before construction begins.
Building permits help ensure your project complies with the Ontario Building Code, municipal by-laws, and applicable safety standards, protecting both your investment and the people who use the building. Greenstone's building permits are managed through the Cloudpermit online system, allowing you to apply, track your application, and request inspections online.
Building without a permit can result in:
- Stop Work Orders
- Project delays
- Additional costs
- Enforcement action
- Complications when selling or insuring your property
Common projects that may require a building permit include:
- New homes and additions
- Garages, workshops, and sheds over the applicable size limits
- Decks, porches, and sunrooms
- Structural renovations
- Basement finishing (in many cases)
- Plumbing or heating modifications
- Demolition of buildings
- Commercial, industrial, and institutional construction
- Changes to the use of a building
