Best Areas to Live in Longmont
Longmont's most frequently cited distinction runs between its historic Old Town/downtown core near the original Chicago-Colorado Colony townsite and newer development further from the city center -- a real, if less sharply documented in this research pass than some other cities in this dataset, geographic pattern worth understanding before choosing a specific area.

Learn moreHistoric Old Town and downtown Longmont
Longmont's historic core, near the original 1871 Chicago-Colorado Colony townsite along the St. Vrain River, retains older housing stock and a walkable downtown commercial district -- a genuinely distinct character from the city's newer development further east and southeast.
ZIP-code-level variation in home prices
This research pass found a real, disclosed price gap between ZIP codes: 80501 ran to a median of $480,000 in February 2026, while 80503 carries a higher effective property tax rate (0.59% vs. 0.57% in 80501), suggesting somewhat higher assessed home values in that ZIP -- a real, if not fully mapped-out-by-neighborhood-name, geographic price variation within the city.
Proximity to St. Vrain Creek is a real, disclosed consideration
Given Longmont's documented September 2013 flood history along St. Vrain Creek -- which affected areas both inside and outside the FEMA-mapped floodplain at the time -- proximity to the creek corridor is a genuine factor worth weighing alongside the more typical considerations of school-zone assignment and commute distance. See insurance-hazard-costs for the fuller flood-history detail.
