Harbor City's housing stock is a mix of established single-family homes, apartments, and multi-family buildings reflecting its post-war growth as part of the Los Angeles Harbor area. Many homes date to the mid-20th century, and the neighborhood's density is typical of the South Bay's urban neighborhoods. The variety of housing types, from older bungalows to apartment complexes, supports a diverse population and a range of housing options across the community.

Harbor City is bounded by the Harbor Freeway to the east and the neighboring communities of Wilmington, Lomita, and Torrance. It is not divided into sharply named sub-districts; rather, it functions as a continuous residential fabric organized around Western Avenue and the regional park. The neighborhood's character varies from older, denser blocks to quieter single-family streets, with the Palos Verdes Peninsula rising to the south.

Harbor City offers an urban-suburban lifestyle typical of the South Bay. Ken Malloy Harbor Regional Park is a daily gathering place for walking, picnicking, and recreation around Machado Lake, and the neighborhood's commercial corridors along Western Avenue provide shopping and dining. Community life is diverse and family-oriented, anchored by schools, parks, and local businesses. Residents benefit from proximity to the port, the beaches, and the amenities of the wider South Bay.

Harbor City's students attend Los Angeles Unified School District campuses, including Nathaniel Narbonne High School, which serves the Harbor City area and the neighboring city of Lomita, along with several elementary and middle schools in the neighborhood. The area includes two high schools and several other campuses. Nearby Los Angeles Harbor College, in Wilmington, provides community college education and transfer pathways for local residents.

Harbor City sits between the Harbor Freeway (110) and the San Diego Freeway (405), two of the region's principal freeways, providing access to the Port of Los Angeles, Long Beach, and the broader Los Angeles basin. Western Avenue serves as a major surface arterial, and Los Angeles County Metro bus routes connect the neighborhood to the region's transit network. The location makes Harbor City convenient for commuters throughout the South Bay and Harbor area.

Ken Malloy Harbor Regional Park is the neighborhood's recreational centerpiece. The 231-acre park features 45-acre Machado Lake, a freshwater bayou wetland, walking paths, and a golf course, and serves as an important habitat for birds and wildlife. The park hosts community programs and educational field trips. Nearby regional amenities include the beaches of the South Bay, the Palos Verdes Peninsula's trails, and the recreational facilities of neighboring Torrance and Wilmington.
