New Single Family Homes in Ottawa

New single-family homes in Ottawa are concentrated in the city's suburban growth corridors: Barrhaven, Kanata, Stittsville, Riverside South, and Orléans. Major builders — including Minto, Mattamy, Richcraft, and Caivan — offer a range of detached models from 1,800 to 3,500+ sq ft, with pricing typically starting in the mid-$500Ks and extending past $1M for executive-class homes. Ottawa's new detached homes are built to modern Ontario energy codes, featuring superior insulation, high-efficiency HVAC systems, and triple-pane windows that reduce utility costs year-round. Most new communities offer 30–40 ft lot frontages, with wider lots available at a premium. When purchasing a new detached home, key decisions include lot selection (orientation, proximity to parks or commercial areas), structural upgrades (finished basement, additional bathroom rough-ins), and finish selections at the design centre. Builder pricing is transparent — there are no competing offers — but the total cost often exceeds the base price by $50,000–$150,000 once upgrades, lot premiums, and development charges are factored in. Having your own REALTOR® at the sales centre ensures your interests are represented in contract negotiations.
