Questions to ask about your lot

What can I build on my lot?

The municipality's zoning by-law restricts what land may be used for and what buildings may be erected. Read the by-law for your lot before you commit to a plan, or ask us to.

Planning Act, R.S.O. 1990, c. P.13, s. 34(1)

What if my plan doesn't fit the by-law?

You can apply to the committee of adjustment for a minor variance. It decides whether the change is desirable and whether the by-law's general intent and purpose are maintained.

Planning Act, R.S.O. 1990, c. P.13, s. 45(1)

How long does the permit take?

For a house, the city issues or refuses a complete application within 10 days. For other classes of building it is 15, 20 or 30 days. Weekends and holidays don't count.

Ontario Building Code, O. Reg. 332/12, Division C, Article 1.3.1.3 and Table 1.3.1.3

Do I need a permit for an addition?

Yes. Nobody may construct a building without one, and constructing includes extension and material alteration. See the permit step.

Building Code Act, 1992, S.O. 1992, c. 23, ss. 1(1) and 8(1)

Start with your lot.

Leave a number or an email and say what you would like to build. The first conversation is about the house you have, what you want from it, and what the by-law allows on the lot.
