Building Permit Frequently Asked Questions

Answers to Frequently Asked Questions

1.  Why is a building permit required?

 Building permits are necessary to ensure zoning requirements (contained in municipal by-laws), and building safety standards (contained in the Ontario Building Code) are satisfied in order to maintain or improve the health, fire and structural standards for the general safety of the public. The Ontario Building Code is a provincial regulation administered by the Building and Development Branch of the Ministry of Municipal Affairs and Housing. Under the Building Code Act, local governments are given authority for the enforcement of the Ontario Building Code within their jurisdiction.

2.  When is a building permit required? (Types of projects)

Under the Ontario Building Code Act, a building permit is required for the construction of any structure exceeding an area of 10 m2. (~108 ft2.).

A building permit is required for new construction, additions, alterations, renovations, relocations, demolitions, and repairs or rehabilitation of a building or structure. Some minor repairs do not require a permit. Listed below are some typical projects and whether or not they require a permit. Heating Ventilating and Air Conditioning permits (HVAC), and/or plumbing permits may also be required as a separate permit but are usually reviewed as part of the overall building permit. It is the responsibility of the owner to obtain a building permit. The approved drawings should be kept on the building site and be readily accessible at all times.

Examples of projects that require a building permit:

  • Finished Basements
  • Accessory Apartments 
  • Decks (regardless of size if attached to house)
  • Accessory Building (shed, gazebo, cabana, carport,      garage, farm building, poly hoop, etc...)
  • Additions (regardless of size)
  • Construction of attached and detached garages
  • Enlarging an exterior opening and any new interior opening in loadbearing      wall

3.  What can result from not obtaining a building permit?

 

It is unlawful to commence construction without a building permit!

If the work does not comply with the Ontario Building Code requirements,

  •  Costly repairs may be required to gain compliance
  •  Removal of work done not in compliance may be required
  •  The building permit application fee may be increased
  •  Legal action may be initiated by the Building Department to gain compliance

If you are still not certain whether or not your project requires a building permit, contact the Building Section of the Planning and Development Department. Our staff will be able to assist you in making that determination.

4. What types of drawings are required?

 Plans must contain sufficient information to enable staff to determine whether the proposed work conforms to all applicable regulations.  For specific residential projects see our Guide to Permit drawings section for required drawing. 

Site plans, five (5) copies required, must be referenced to a current plan of survey, certified by a registered Ontario Land Surveyor. A copy of each survey must be submitted with the permit application for most projects. Site plans showing outlines and dimensions of the property, driveways, and existing and proposed buildings may be accepted.

Where required by the Ontario Building Code, drawings must be prepared, sealed and signed by an Architect, Professional Engineer, or both. Two copies of all plans are required for each application.

 

 

5. How do I apply for a building permit?

The owner or his/her authorized agent must file an application, in writing. Proper drawings and specifications must accompany every application. Incomplete applications/drawings will not be accepted.

6. Who will review permit plans?

Permit plans will be reviewed by staff for compliance with the Zoning By-law, Ontario Building Code and other related standards and by-laws. Development Engineering staff will review the proposal with respect to grading and drainage. Where applicable, the Fire Department will examine the plans for compliance with fire safety provisions contained in the Ontario Building Code, the Ontario Fire Code (where applicable) and related standards.

7. Who obtains the approvals from other agencies?
