Do I need a Building Permit?

The Ontario Building Code requires that you obtain a building permit before you start work on a new building or an addition or any significant alterations to an existing building. The Building Code sets out the minimum requirements for such work and is particularly concerned with your health and safety and that of other homeowners, building occupants, future owners and the community.

The Ontario Building Code is a regulation made under the Building Code Act. The Code is essentially a set of minimum provisions respecting the safety of buildings with reference to public health, fire protection and structural sufficiency. It is not intended to be a textbook on building design, advice on design should be sought from professional sources. Its primary purpose is the promotion of public safety through the application of appropriate uniform building standards. The provisions in this Code are intended to provide a minimum acceptable level of public safety and building integrity. They are not intended to be applied to voluntary installations unless specified in the Code.

NOTE: IT IS ILLEGAL to begin construction before a Building Permit has been issued by the Municipality. Violations are subject to prosecution.

Building Permits are required for but not limited to;

1) Any building over 10 square metres (108 square feet) or any additions to these including decks, docks and boathouses
2) Any dwelling unit or addition
3) Any material or structure change
4) Any wood burning appliance or chimney
5) Any plumbing or building with plumbing in it
6) Change the use of a structure
7) Replacing a deck
8) Tents - a tent or group of tents that is more than 60 sq. metres (645 square feet) in aggregate ground area
9) Solar panel installations on a building or structure

Before you start to prepare your drawings, you should check that your proposal will comply with the Township of Seguin's, Zoning By-law. The Zoning By-law specifies minimum setbacks from property lines, maximum lot coverage and other zoning standards that may limit your proposal. It's best to find out if these limits will affect your project before you start preparing your drawings.

If you are unsure if your project requires a Building Permit and for more information, please contact the Building Department.
