Editing Brentwood, Maryland (section)

===20th century===
The community continued to grow in the early 20th century. A school was built, and the Brentwood Citizens' Association formed in 1903, a [[Methodism|Methodist]] church was constructed in 1904, a fire department was started in 1905, and was formed in 1903. [[Kerosene]] street lamps were added in 1917, and electric lights were installed in 1920. When incorporated, the town included the southerly part of the Holladay Addition, the Brentwood Company subdivision, and two smaller additions.<ref name="Denny" /> The houses built during this time consisted of small frame [[bungalow]]s. Growth continued through the 1940s and 1950s, fueled by an influx of government workers. In the 1950s, many older homes were replaced and empty lots were filled with small cottages and [[ranch-style house]]s.<ref name="Pearl" />

The majority of homes in Brentwood were built during and after World War II; young people coming to Washington, D.C., to support the war effort found a quiet place to raise their families. There are two small service-oriented commercial areas. A focal point is Bartlett Park named for Captain Bartlett who deeded the land to the town. The park is home to the Wohlfarth Building, which serves as the Town Hall.<ref name="mml" />
