Unofficial Zoning Map (updated 7/2012)

What is zoning?


Zoning is a series of ordinances adopted by the city council which set standards for the location, size of buildings, and for use of buildings and land throughout the city. It is the primary tool to implement the city’s comprehensive plan, the “COMPLAN,” and to provide for compatibility of neighboring land uses. The zoning ordinance consists of various districts. Each district has development standards such as permitted uses, building height, parking, setback, and minimum open space.

What are the various districts?

In the Littleton Zoning Ordinance we have the following districts. See the unofficial Zoning Map for more information.

What does “setback” mean?

“Setback” refers to the minimum distance a structure must be located away from all property lines. Be careful not to make the common mistake of assuming a property line is along a street, gutter or sidewalk.

Minimum setback requirements for a single family home (entire principal structure including attached garage, decks, etc.) in an R-2 zone district are 25 feet in the front, 20 feet in the rear, 5 feet on the north or west side, and 10 feet on the south or east side. (The applicable side setback depends on which way the house faces.) Any accessory structure (detached garage, shed etc.) also has setback requirements. Most properties also have utility easements upon which no structure can be placed, regardless of the setback. Check with the zoning office at 303-795-3748 for setbacks specific to your property.

Are there guidelines for fences?


Yes. In a residential district a fence can be a maximum of 6 feet high anywhere behind the front setback or next to a public right-of-way, a fence can be a maximum of four feet high and must be 50 percent open (for example, split rail, picket or chain link). Don’t forget, a permit is required from the building department before any fence can be erected.

What is a nonconforming use or structure?

A building, or a use of land, is nonconforming if it was lawfully operated within any zone district prior to the effective date of an ordinance or amendment that prohibits the building or use. A nonconforming use or building may continue to exist or operate on the property even after the original owner transfers the property. However, enlarging or terminating a nonconforming use will change this status.

What is a conditional use?

The City's Zoning Ordinance identifies certain uses within the city as conditional uses. These are uses permitted within certain zone districts, which may exist only upon the imposition of conditions to mitigate negative impacts on adjacent properties. Conditional uses include utility installations, childcare centers and private schools, radio transmission towers/wind generators, indoor amusements, commercial outdoor recreational uses, solid waste incinerators/transfer stations, off-site parking for commercial uses, commercial teen clubs, community correctional facilities, circuses and carnivals, and sale and leasing of used motor vehicles, animal boarding and care facilities. The Planning Board reviews and approves or denies conditional uses at a public hearing.

Am I within the city boundaries?

See city limits map. Please note that not all Littleton mailing addresses are within the city's jurisdiction.
