Modifying Townhouses

Modify or expand townhouses is limited by shared walls and lot size. Typically 1,500–2,500 square feet, interior renovations like open-concept layouts cost $5,000–$20,000. Finishing basements, common in Ontario, adds space ($15,000–$40,000) but requires moisture checks. Adding rooms is challenging due to small lots and HOA restrictions. Vertical expansion is rare ($50,000+). Compared to detached homes, townhouses offer less flexibility but more than condos. Buyers should verify zoning and HOA rules during tours, ensuring modifications suit needs in Ontario’s market.
