About This Property

Approved shovel-ready triplex development opportunity in St. Catharines! Calling all investors, builders, and savvy buyers. This is a rare opportunity to begin construction immediately with an approved triplex building permit already in hand, avoiding months of planning delays and significant soft costs. Completed plans provide for approximately 3,900-4,000 sq. ft. of total build, designed as three self-contained residential units featuring efficient layouts, multiple washrooms, and modern exterior elevations with strong rental appeal. Ideal for investors seeking long-term cash flow, a BRRRR strategy, builders looking for a ready-to-go project with approvals secured, or an owner-occupier looking to live in one unit while renting the other two for supplemental income. Situated in a desirable neighbourhood close to schools, Montessori and childcare centres, parks, public transit, shopping, and everyday amenities, with convenient access to downtown St. Catharines, Brock University, the Pen Centre, and major routes. A turnkey multi-unit development opportunity in a growing rental market.
