An alley or alleyway is a narrow service road usually located between properties to provide access things such as back gardens, rear entrances, fire exits, and storage areas. Alleys are normally found in urban areas and often run between the rear sides of buildings such as houses, and commercial premises.

If a narrow street is prohibited for motor vehicles, consider using highway=footway or highway=pedestrian.

Medieval ways

In some (e.g. medieval European) settlements alleys may be the very narrow streets which run in-between buildings, providing public through-access. These may be mapped using service=alley.

Alley Streets

Alley streets are a road classification found in Baltimore, Maryland, USA[1], and potentially other places. Alley streets are alleys by definition, i.e., they serve the rear of buildings, but are named. Most named alley streets have addresses assigned to them, often small homes or carriage-houses that have been converted into homes, due to Next Generation 911 (NG911) standards that require local governments to sign any public street with addresses. Alley streets may have sidewalks but they are small and designed to house trash cans or steps down from homes. Alley streets do not typically have on-street parking, which distinguishes them from residential streets.
