About this home
Fantastic opportunity! First time to market in many decades. Vacant, undeveloped building lot with street frontage to SW 143rd St in Burien. Generously sized at 10,474 sq ft and zoned R3, this property offers many possibilities for development. Multiple residential units, townhomes, DADU/ADUs, cottages, and more! The property qualifies for the transit proximity bonus. Buyer to verify all development info to their own satisfaction. To the east is a contiguous 13,790 sq ft lot, also for sale. Together, the parcels offer 24,264 sq ft and almost 150 ft of street frontage. See MLS#2585770 for the other parcel's listing. Preliminary feasibility report and development capacity analysis are provided, as well as recent topographical and boundary survey, and arborist's report. Feasibility analysis estimates that 12 units could be built on the two lots, weighing various factors delineated in the report. Public water, public sewer, electricity and gas are already in the east parcel as a livable single family residence is there. Fabulous location near the vibrant restaurants and shopping of Burien, with great public transit options and only 10 miles to downtown Seattle.
