New Homes in Ottawa Under $600,000

Under $600,000, Ottawa's new construction market opens up to include starter detached homes, premium townhomes with upgraded finishes, and semi-detached properties in established communities. Builders like Minto, Richcraft, and Tamarack offer single-family homes in this range in communities such as Riverside South, Barrhaven, and Stittsville — typically 1,800–2,200 sq ft with three to four bedrooms, main-floor laundry, and energy-efficient builds that meet modern Ontario Building Code standards. This price point is particularly popular with growing families upgrading from condos or townhomes. Lot sizes in newer communities tend to be compact (30–35 ft frontages), but builders compensate with efficient floor plans and open-concept living spaces. When buying a new detached home under $600K, pay close attention to lot premiums (corner lots, backing onto green space), included vs. upgraded finishes, and the builder's track record on closing timelines. Ottawa's Tarion warranty provides deposit protection and structural coverage, but your REALTOR® should review the purchase agreement's delay and cancellation clauses before you sign.
