While strolling back from Chautauqua, consider stopping by 757 12th St - an approximately 6,116 sq ft building lot just three blocks from Chautauqua Park, nestled beneath the Flatirons on a quiet, mostly owner-occupied street. Established neighborhood with strong pride of ownership, lush foliage for privacy, and world-class hiking and biking trails, just minutes away. Level, buildable lot with alley access and utility hookups available. Water and sewer taps paid previously, cable TV available, partially fenced. The lot allows up to 3,323 sq ft of floor area and 2,273 sq ft of building coverage, with a 32.47 ft height limit. A basement, in addition to above-grade square footage, can be habitable with reasonable egress. Substantial entitlement work has been completed in the past. Previously approved plans (since voided for inactivity) called for a 2-story single-family home - 1,882 sq ft of interior living plus a 480 sq ft attached 2-car garage above grade, over a 1,418 sq ft finished basement - while preserving the existing 396 sq ft historic landmarked carriage house. The historic carriage house may have potential for ADU conversion (carrying historic designation; the lot itself does not), as previously confirmed by the city. Included in the sale: blueprints, soil reports, and the previously approved architectural plans. Boulder real estate has demonstrated strong appreciation, and, an opportunity in a location this hard to replicate, doesn't come along often. All information herein is deemed reliable but not guaranteed. Buyer and Buyer's Agent are responsible for independently verifying all information directly with the City of Boulder prior to closing.
