Description

Incredible opportunity to redevelop this 7,000 sq. ft. corner lot in prime San Mateo location. This property is being sold with the adjacent 3,000 sq. ft. vacant lot (See ML81866553). Unlimited possibilities for these two properties totaling 10,000 sq. ft. The current 1,700 sq. ft. home has been taken down to the studs due to fire damage and is ready to rebuild or combine the two lots to build a new home with ADU. This is truly a unique opportunity for an investor or contractor. Must check with the City of San Mateo for any building restrictions.
503 Alta Ave, San Mateo, CA 94403 is a 3 bedroom, 2 bathroom, 1,730 sqft single-family home in Country Club Heights, built in 1948. It is currently off market. The Trulia Estimate rent is $6,666/month.
