DCA periodically reviews, amends and/or updates the state minimum standard codes. If a local government chooses to locally enforce any of these codes, it must enforce the latest editions and the amendments adopted by DCA.
The Building Department was created to administer and enforce building, heating, ventilation, air conditioning, electrical, plumbing, sanitation, sign codes and standards, to provide minimum standards for the protection of life, limb, health, environment, public safety and welfare, and for the conservation of energy in the design and construction of buildings and structures.
The large cast consists mainly of actors who are little known for their other roles, as well as numerous real-life Baltimore and Maryland figures in guest and recurring roles. Simon has said that despite its framing as a crime drama, the show is "really about the American city, and about how we live together. It's about how institutions have an effect on individuals. Whether one is a cop, a longshoreman, a drug dealer, a politician, a judge or a lawyer, all are ultimately compromised and must contend with whatever institution to which they are committed."
Central to the show's aim for realism was the creation of truthful characters. Simon has stated that most of them are composites of real-life Baltimore figures. For instance, Donnie Andrews served as the main inspiration of Omar Little. Martin O'Malley served as "one of the inspirations" for Tommy Carcetti. The show often cast non-professional actors in minor roles, distinguishing itself from other television series by showing the "faces and voices of the real city" it depicts. The writing also uses contemporary slang to enhance the immersive viewing experience.
In a final montage, McNulty gazes over the city; Freamon enjoys retirement; Templeton wins a Pulitzer; Carcetti becomes Governor; Haynes is sidelined to the copy desk and replaced by Fletcher; Campbell appoints Valchek as commissioner; Carcetti appoints Rawls as Superintendent of the Maryland State Police; Dukie continues to use heroin; Pearlman becomes a judge and Daniels a defense attorney; Bubbles is allowed upstairs where he enjoys a family dinner; Chris serves his life sentence alongside Wee-Bey; the drug trade continues; and the people of Baltimore go on with their lives. 2b1af7f3a8
