The City of Littleton itself centers on its historic downtown along Main Street and the South Platte River corridor, with older homes near downtown and neighborhoods of 1950s through 1970s ranches, split-levels and two-stories spreading outward. But the Littleton name on mail reaches well beyond the city: large unincorporated areas to the west and southwest in Jefferson County, and areas to the south in Douglas and Arapahoe counties, use Littleton addresses too.

In everyday life that hardly matters. After an unattended death, an injury or a crime, it can matter a great deal. Law enforcement may be the city police or a county sheriff's office. The coroner depends on the county. Permits for repairs come from the city or the county, depending on where the property actually sits. Families arriving from out of state, trying to manage a parent's home, are often surprised by this.

Common questions

If a parent lived in an assisted living apartment, who arranges cleanup?
Usually the community's management works with the family. Ask what the residency agreement says about cleaning and repairs and who pays for them.
