Custom Home Construction in Waterloo
Waterloo Council voted in December 2024 to allow four units and four storeys in low-rise residential areas. A custom home rebuild can now reach 10 m, or 13.5 m for a four-unit building. Owners in Westmount and Beechwood now compare a large single house, a house with an ARU and coach house, or a purpose-built fourplex.

Worth knowing first
Sandy moraine soils under west Waterloo lots
Much of west Waterloo sits on the Waterloo Moraine, sandy ground that recharges the Region’s wells. Those soils drain well, but a deep excavation beside a neighbouring house can need shoring. Open sites on the Waterloo Moraine erode quickly, so erosion control goes in before digging starts. The same area lies inside Waterloo Region wellhead protection areas. Storing fuel oil and some chemicals is prohibited or regulated there, and certain geothermal systems may need Region review before the City issues a permit. For a typical gas or heat-pump house, the design barely changes. We check the Region’s mapping and order a soils report before foundations are final.
The scope, pricing tiers and 5-step process are the same everywhere we work. See Custom Home Construction ›
Frequently asked questions
Custom Homes in Waterloo: three local questions
Up to 10 m for most residential buildings and 13.5 m for a building with four units, under the zoning Council approved in December 2024. Setbacks, lot coverage and parking still apply, and they usually limit the building before height does. Going beyond the limits needs a minor variance. On narrow lots near Uptown Waterloo, side-yard setbacks and the 7 m driveway cap decide the footprint.
Parking, setbacks and access, in most low-rise zones. The lot must fit three parking spaces, the setbacks and a walkway to each unit, and a new four-unit building can reach 13.5 m. It pays City, Region and school board development charges on units that aren’t exempt, with a possible credit for the demolished house. Each rented unit then needs its own Waterloo rental licence.
Both the demolition and the new building need one. The MacGregor-Albert district plan guides height, setbacks, porches, rooflines and materials so new houses sit well on the older street. Removing a house that contributes to the district’s character is hard to justify. Meet the City’s heritage planner before paying for full drawings. A design that follows the MacGregor-Albert plan from the first sketch moves faster.
