Service Level during the Covid-19 Pandemic: The City of Cambridge Building Division is here to make sure homes, buildings and structures in our community meet the provincial building code and are built right. This means examining and inspecting building construction and interpreting and applying the Ontario Building code.
- The building division is reviewing and processing all building permit submissions.
- The building division is conducting site inspections for all construction projects.
Please note: Due to a record amount of applications being received currently, delays issuing permits within the standard timing can be expected. We apologize and are working hard to get back on track. Thank you for your patience during this time.
A Building Permit is your formal permission to begin construction, demolition, addition or renovation on your property. Building permits are required for your safety and the safety of those around you, ensuring your construction project is protected from structural failure, fire hazards from electrical and heating systems, and other health risks. They also provide a permanent record of the work performed and all inspections conducted to ensure the project is sound and safe.
Ontario's Building Code Matters
As part of the building permit process, Cambridge's Building Division staff must review your plans to ensure they comply with the Ontario Building Code, local Zoning Bylaws, and other Applicable Law.
Once your permit is issued site inspections must be performed by a city building official to ensure construction is completed in accordance with the approved plans and code requirements.

| Cross connection control |
The Cross Connection Control Program is in place to ensure the safety of our water supply through backflow prevention.
The City of Cambridge Water Use By-law #146-03 requires that all buildings (except some residential properties) be equipped with backflow prevention devices. These devices need to be maintained and tested regularly by a certified backflow prevention device tester licensed by the City of Cambridge.
Please follow the Instructions for Compliance to the Cross Connection Control/Backflow Prevention Program
* NEW - The Cross Connection Control Program at the City of Cambridge is going paperless!

| What is backflow and how would this occur? |
|
Backflow means a flowing back or reversal of the normal direction of water flow.
The water supply system is normally pressurized to make sure water flows into your building or plumbing system, but there are times that pressure may be reduced.
If the pressure drops enough that the flow of water reverses, unwanted substances could flow backwards and contaminate the public water supply.
|
| What is a Cross Connection? |
|
A cross-connection is any connection, whether permanent or not, between the public potable water system and a possible source of contamination.
Some examples of cross-connections are fire sprinkler and irrigation systems, or plumbing connections to equipment that uses water, such as beverage machines, dental chairs and dialysis equipment.
|
| What is a backflow prevention device? |
| Backflow preventers are mechanical devices that prevent water from flowing backwards into a 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. The type of device required and location it is installed depends on the application and the threat level. |

| Permits |
| A building permit is required for a new backflow preventer or new plumbing system. Visit the building permit page or contact building@cambridge.ca for more information. |
| What if I choose to not install a backflow device? |
|
The by-law mandates that every building, except for some residential buildings must be equipped with backflow prevention devices. Failure to install and maintain these devices could result in having your water shut off, and/or a fine.
