About 538 Mutual Street
Exceptional development opportunity in the heart of Castle Heights. Situated on a 60' x 111' lot and currently improved with a tenanted triplex providing holding income, this property offers compelling future redevelopment potential. A substantial rear concrete block building with high ceilings-larger than the existing residential structure-creates a rare opportunity for adaptive reuse or future development, subject to buyer due diligence and required approvals. Zoned N4B (buyer to verify), the property may support a variety of residential development concepts under Ottawa's evolving zoning framework. Located in a neighbourhood experiencing significant reinvestment and infill activity, this is an outstanding opportunity for builders, developers, and investors seeking both current income and long-term upside. AI renderings included for illustration purposes only. Buyers are advised to verify zoning, permitted uses, development potential, and all approvals required for their intended use.
3 bedrooms, 3 bathrooms, about 2,500 sq ft, works out to roughly $300 per square foot, the bed-to-bath ratio is generous. Chat with Zara if you'd like a deeper read on whether this detached fits your budget and timing.
