3711 15 Street SW is a high-density multifamily development site located in the sought-after inner-city community of Altadore, Calgary. The freehold parcel measures approximately 1,155 m² (12,433 SF) and has been re-zoned to M-C2, with a development permit approved for a 31-unit apartment building. The property has been cleared and prepared for construction, significantly reducing entitlement and pre-development risk. The site is positioned within one of Calgary’s most established and supply-constrained residential neighborhoods, benefiting from proximity to Marda Loop retail amenities, established transit routes, and strong historical rental demand. The offering is well suited for developers or build-to-hold investors, with the vendor highlighting potential CMHC-insured financing strategies for long-term rental execution.
