Municipal fees

When you build an ADU, there may be fees to support the costs of growth such as: Municipal development charges, Education development charges, and Cash-in-lieu of parkland dedication fees. Use our ADU Fee Estimator tool to get a quick estimate for your project.

‍

Site Services

Your property must have adequate water and wastewater capacity to support the new unit. ADUs must connect to municipal services, where available. Property owners are responsible for any costs for upgrading pipes to allow for an ADU. This includes both private property and within the right-of-way. To learn more, visit the Site Servicing: Installation, Replacement or Repair page.
