Atwater's housing stock is dominated by single-family homes, many built during the mid-century era when Castle Air Force Base drove local growth. The city also contains a mix of older central-neighborhood homes, apartments, and newer subdivisions on its expanding edges. Homes are typically modest in scale, set on standard lots, and reflect the practical, no-frills character of the San Joaquin Valley. The presence of rental housing and a range of home sizes makes the city accessible to first-time buyers, military and aviation workers, and families, with more spacious parcels available on the rural outskirts.

Atwater's neighborhoods range from its historic central blocks, laid out when the city was an agricultural railroad community, to the residential areas that grew up around Castle Air Force Base. Castle Gardens is a family-oriented neighborhood known for its proximity to schools such as Bellevue Elementary and Peggy Heller School. Newer subdivisions have been built on the city's edges, while the area around the former base, now Castle Airport, hosts a mix of aviation, logistics, and employment uses. Overall, the city has a spread-out, low-rise residential feel with clearly defined commercial corridors.

Atwater offers a grounded, family-oriented Central Valley lifestyle. Community life revolves around local schools, neighborhood parks, and small businesses along the city's commercial corridors, with the larger amenities of Merced only minutes away. The city's military heritage remains a point of local pride, visible in the Castle Air Museum and the redevelopment of the former base. Residents value the town's small-city feel and its practical access to the wider region, from Fresno to Sacramento, while enjoying a lower-key pace than California's coastal metros.

Public education in Atwater is provided by two districts: the Atwater Elementary School District for grades K-8 and the Merced Union High School District for grades 9-12. Elementary schools such as Bellevue and Peggy Heller School serve the city's neighborhoods, while older students attend area high schools in the Merced Union system. For higher education, Merced College and the University of California, Merced are both nearby, giving residents access to community college programs and a major research university without leaving the county.

State Route 99 is Atwater's principal transportation corridor, carrying traffic north toward Modesto and Sacramento and south toward Merced, Fresno, and points beyond. The Atwater-Merced Expressway helps route commuter and freight traffic through the growing area, and the city sits within a short drive of Merced's Amtrak station on the San Joaquin corridor. Commuters heading to UC Merced, the county government offices in Merced, or jobs along the Highway 99 industrial spine find the city's central location convenient, with regional airports in Fresno, Stockton, and the Bay Area for longer trips.

The Castle Air Museum is Atwater's signature attraction, displaying dozens of historic military aircraft on the grounds of the former air base and drawing aviation enthusiasts from across the region. The city maintains neighborhood parks and community facilities, while nearby Merced offers additional recreation, including Lake Yosemite in the eastern part of the county. Atwater's Central Valley location also makes it a convenient staging point for trips to Yosemite National Park and the Sierra Nevada, reachable by highway from Merced.
