About this property
Opportunities like this rarely hit the market. 149 Lake Street occupies a premium, high-visibility corner at Lake & Beech St, entering downtown St. Catharines, and is now available with vacant possession. Quality commercial buildings in this location are tightly held, and when one becomes available, it does not stay available for long. Prominent, versatile and ready for its next owner, this two-storey mixed-use building offers 1975 square feet of functional space. The M1 zoning provides exceptional flexibility across commercial and residential uses, permitting professional office, retail, cafe, restaurant and similar uses, in addition to residential. It is an exceptional fit for professional owner-operators, accountants, lawyers, financial advisors, medical professionals and established local businesses, who are ready to invest in owning their own premises, rather than continuing to lease. For an investor, it offers conversion and income potential in a proven commercial location. Long home to an established professional insurance practice, the main floor is configured for office use, while the upper floor presents a compelling residential conversion opportunity above the commercial space. The lower level is protected by a $15,000 basement waterproofing system, installed proactively and complete with a new sump pump. Upgrades include: roof replacement in 2017, main plumbing stack replaced in 2026 and fencing dating to 2018. On-site parking handles five vehicles, with room for up to ten. The existing sign post stays for your business signage. Make this prime corner the new home of your business.
