Frequently Asked Questions

How tall can a single-family house be in Littleton's NC district?
Up to 35 feet, under Table 10-3-2.2.1, Residential Lot and Building Standards, adopted under Section 10-3-2.2 of the Unified Land Use Code. The same table also sets a 6,000-square-foot minimum lot area and a 50-foot minimum lot width for that use.
Can a residential building in Littleton's Corridor Mixed district be taller than 35 feet?
Yes. Table 10-3-2.2.1 allows a multiplex in the CM district up to 45 feet, and a multi-family building up to 55 or 65 feet where the project qualifies for the density and height bonus under Section 10-1-3.4, Sustainable Building Design.
Do these height limits apply to an existing house I'm remodeling in Littleton?
Not necessarily. Table 10-3-2.2.1 governs new residential development in the NC and CM districts. Construction or additions to existing homes in pre-established CM neighborhoods instead follow the Contextual Development standards in Section 10-4-3.2.C or the Neighborhood Conservation standards in Section 10-4-3.2.F.
