1144 Mapleton Avenue sits where Mapleton Hill meets downtown Boulder, just west of Broadway, where tree-lined residential streets meet the city's liveliest blocks. Pearl Street's restaurants, shops, galleries, and cafes are just a few blocks to the south. Mapleton Avenue runs west toward the Mount Sanitas trailhead, with the mountains forming a constant backdrop to daily life. Mapleton Hill is one of Boulder's oldest and most recognizable neighborhoods. It's known for its historic homes, established gardens, and close connection to both downtown and the foothills. This is a vacant, unimproved lot. With no existing structure to work around, it offers a clean starting point for a custom in-town home in one of the most established and admired parts of the city, an opportunity seldom found this close to downtown. Whether envisioned as a personal residence or an investment, the site invites a home defined by thoughtful design and lasting quality. Frontage on Mapleton Avenue paired with convenient rear alley access offers options for how a future home, garage, and outdoor space might be arranged across the site. A completed survey and feasibility study are available, giving buyers, architects, and builders a meaningful head start on planning and due diligence. The lot sits within the Mapleton Hill Historic District, among homes whose architecture has shaped the character of these streets for more than a century. This lot offers the chance to build something new within the fabric of historic Boulder, designed around its owner's vision rather than adapted from someone else's plans. Mornings can begin on the Sanitas trails and evenings can end over dinner on Pearl Street, with a quiet, tree-lined street to come home to in between. It's an opportunity to put down roots in the heart of downtown Boulder, on your own terms.

Mapleton Hill, located between Broadway and 9th Street, is a historic and residential Boulder neighborhood with tree-lined streets and landmark Victorian-era architecture. The neighborhood’s character concentrates around the Mapleton Avenue and Broadway corner, where café patios and small storefronts meet the steady rhythm of campus-bound traffic. Community pillars include the Boulder Theater, the Boulder Museum of Contemporary Art, and the Boulder Public Library’s Main Branch. Brick sidewalks and deep front porches set a classic streetscape, while views toward the Flatirons frame many blocks. North Boulder Park and nearby trailheads shape an outdoors-forward routine without leaving town. Pearl Street’s pedestrian energy sits just downhill, balancing quiet blocks with a lively cultural calendar.
