As a Census-Designated Place, the Lazy Mountain Area is not a traditional village or town. It lies to the east of the nearest municipal area, Palmer. The area is part of the Matanuska-Susitna Borough, and as such is subject to borough control. The Lazy Mountain Community Council, which represents a similar but slightly smaller area than the Lazy Mountain CDP, provides feedback to the borough from some of the residents of the area. The Lazy Mountain Community Council submitted a Comprehensive Plan to the Borough Assembly, and it adopted by the Assembly in 2008.

The Lazy Mountain Recreation Area is a 360-acre site which has hiking, skiing, and equestrian trails. The parking area at the East end of Huntley Road provides access to the Morgan Horse, Lazy Moose and Lazy Mountain Trails.

The Lazy Mountain area is only accessible by road along the Old Glenn Highway, formerly Alaska Route 1. This section of the Glenn Highway was bypassed when the Glenn Highway was rerouted across the Knik and Matanuska Rivers and the Palmer Hay Flats in 1976. The Old Glenn Highway is now reached from the south at an interchange off of the Glenn Highway at milepost 29.6, or from Palmer where the Old Glenn becomes Arctic Avenue. The Old Glenn Highway is classified as a major collector South of Clark-Wolverine Road, and as a minor arterial from that point north into Palmer.

East Smith Road, which forms the southern boundary of the Lazy Mountain CDP, is considered a minor collector road for the first 1/2 mile from the Old Glenn Highway, as is Clark-Wolverine Road from the Old Glenn Highway all the way to where it becomes Wolverine Road, and on to N. McKenzie Drive
