The following is detailed list of commonly requested applications, licences and permits related to building, development and roads in the City of Cambridge.

Addressing and renumbering

According to the Municipal Addressing By-law, the City may provide a change of address notice to the property owner, if needed.

A property owner can also request an address change by completing an address number change application and submitting an application fee.

Please note that the City may not approve all address number change requests.

Building permit
There are a number of different types of building permits issued by the City of Cambridge. You must apply for the appropriate permits before your project can begin.
Cross Connection Control/Backflow Prevention Device Testing

Cross connection control protects the quality of our drinking water through backflow prevention.

What is backflow and how would this occur?
Water is normally maintained at a significant pressure to enable water to flow from the tap, shower etc. If a water main bursts, pipes freeze or there is unexpectedly high demand on the water system, the pressure in the pipe may be reduced. During these types of events, the pressure may be reduced enough to reverse the intended flow of water and actually draw water out of nearby service connections. If these connections are affixed to chemical mixing facilities or any non-potable water supply, the possibility exists that dangerous backflow can occur resulting in contamination of our public water supply.
What is a backflow prevention device?
This is a device that prevents water from flowing backwards into a water supply line resulting in a contaminated water supply. There are degrees of protection ranging from a vacuum breaker on a garden hose line to reduced pressure zone backflow preventers commonly used in an industrial setting where chemicals are connected to water lines. What is used and where it is installed depends on the application and the threat level.
What do I as a property/building owner need to do?

By-law No. 146-03 requires that all building owners, except some residential properties equip their buildings with backflow prevention devices. These devices need to be installed and maintained/tested on a regular basis. This must be done by a backflow prevention device tester licensed by the City of Cambridge .

Please complete the contact information sheet and review instructions for annual testing.

Test reports must be submitted annually, and equipment surveys must be submitted every three years. 

At the design stage of a new building or addition a design level cross connection survey must be submitted with the building permit application.

What if I choose to not install a backflow device?
The by-law is clear that each building, except for some residential buildings require backflow prevention devices. Failure to equip the building and maintain these devices could result in having your water shut off, and/or a fine of up to $5,000.00.
Is there any fee or permit involved?

No. The annual testing and survey reports do not require a fee. However, if a new device needs to be installed it would require a building permit which would require a fee.

Please contact the Backflow Officer at (519) 621-0740 ext. 4514 for more information.

Pool, hot tub and pool enclosure permits

There are number of rules and regulations involved with installing a pool, hot tub or pool enclosure. View Section 2.1.11.2 of the City's Zoning By-law for regulations related to pool or hot tub locations.

Swimming pools and hot tubs

You need to apply for a permit to install a swimming pool or hot tub. To complete your permit application, you'll need the following:

  • A survey that shows the location of the pool or hot tub and its distance from other structures and property lines
  • A simple description of the pool or hot tub
  • A diagram of the type of fencing you will construct around the pool or hot tub
  • A method of payment for the applicable fees
  • A completed application form
Fences

You do not need a permit to install a fence, except around pools and hot tubs. However, you do need to follow the City's Fence By-law regulations for the height, location and types of fences allowed.

If a property owner wishes to install a fence that does not meet City regulations of the Fence By-law, we can review the case. If the case is valid, Cambridge Council may approve an amendment to the Fence By-law.

You must submit an amendment application along with a fee to the Director of Building & Enforcement Services. Keep in mind that not all applications are successful.

You may view a copy of the Fence Amendment Application.
