An unparalleled opportunity awaits in Old Town Superior! This build-ready lot in a quiet, established neighborhood offers the rare freedom of NO HOA, allowing you to design your dream home without restriction. A massive advantage for any builder, the water, sewer, and gas taps are already paid and on-site, saving significant time and expense. The lot is perfectly situated with easy access to Hwy 36 for commuting and is just steps from shops, restaurants, parks, and Downtown Superior. The valuable rear alley access provides off-street parking for an RV and a unique opportunity to build an Accessory Dwelling Unit (ADU) for rental income. Professionally cleared through Boulder County with a soil report available, this beautiful property—complete with its mature willow tree and heritage boulder—is a unique and valuable canvas.
