Welcome to 15 Hazelwood Crescent SW, a beautifully maintained and extensively upgraded 5 bedroom bungalow in the sought after community of Haysboro. This home combines classic bungalow charm with numerous modern improvements, including newer triple pane windows throughout with Hunter Douglas blinds, 200 amp electrical service, extensive electrical upgrades and permitted work to the kitchen and basement. The main floor features beautifully refinished hardwood floors, a spacious living room, dining area and updated kitchen with permitted electrical work completed in 2025, pot lights, updated lighting and a new microwave/hood fan. Additional updates include a new front door, interior doors, permitted upstairs washer and dryer installation, gas line work and newer attic insulation added in 2022 for improved comfort and efficiency. The fully developed basement adds significant living space with two bedrooms, a 3 piece bathroom, separate laundry, separate entrance and large egress windows in each bedroom. Recent renovations include new insulation, drywall, flooring, basement sink and extensive soundproofing with 6 inch Rockwool insulation, resilient channel and soundproofing materials. The basement is currently configured as an illegal suite and is not being represented as a legal or income generating suite. The property is zoned R-CG, where a Secondary Suite is a permitted use under the current City of Calgary Land Use Bylaw, subject to all applicable development, building, safety and permitting requirements. R-CG zoning also provides future flexibility, with Backyard Suite listed as a discretionary use under the current City of Calgary Land Use Bylaw. This may provide potential for a future detached backyard living space, such as a carriage house, subject to Development Authority approval and applicable City requirements. Buyers are encouraged to conduct their own due diligence regarding future development opportunities. The massive south facing backyard is a standout feature, offering sunshine throughout the day along with a large raised deck, stone patio, firepit, garden beds and plenty of grass for kids and pets. Mature lilac trees line the property, while the fully fenced yard provides excellent privacy and access to the single detached garage. The main level also offers excellent flexibility for working from home or operating a business. The property currently operates under an active home massage practitioner licence, with potential to apply for a Home Occupation Class 2 permit or pursue other approved business uses, subject to City approval. Ideally located near Southland LRT, shopping, schools, parks and amenities, with convenient access to downtown. With five bedrooms, extensive upgrades, a large south facing lot, detached garage, versatile basement and future development potential, this is a fantastic opportunity in Haysboro.
