  • erect, install, extend, alter or repair a building
  • demolish all or part of a building
  • perform construction or alterations that result in a material change to a building or an accessory structure 
Planning to build or renovate?

If you are planning on doing any construction or demolition work, you must understand and follow the process, procedures and requirements. By doing this you will:

  • save time and money
  • avoid receiving an Order to Comply due to unauthorized work
Check on the status of your building permit application

You can find out the status of your Building Permit using the online online Building Permit search. You can use this tool 24 hours a day, seven days a week.

Homeowners or contractors can find out if their Building Permit application:

  • is approved
Who's responsible for scheduling a building inspection?

The Building Permit holder, who can be the owner or contractor, is responsible for:

  • calling to arrange inspections at the required inspection stages
  • ensuring construction meets the Ontario Building Code.

Contractors can also schedule building inspections on the permit holder’s behalf. Make sure you set up your inspections on time to avoid delays.

How much will a Building Permit cost?

Building Permit fees are determined by Hamilton’s Building Permit By-law 08-161. 

Permit fees shall be calculated based on the formula of Permit Fee= SI x A, unless otherwise specified. Where SI = Service lndex for the applicable Classification of the by-law of the work proposed, and A = floor area in m2 of work involved.

Do I need a permit to build a fence?

You do not need a Building Permit to construct a fence unless you are installing a swimming pool or replacing an existing pool enclosure (fence).

Hamilton’s Fence By-law No.10-142 provides the requirements for fences on residential, commercial and industrial zoned properties.
