Sour Lake's housing stock reflects a small Southeast Texas town shaped by the oil era. Single-family homes on town lots make up the core, with a mix of older houses and newer construction, and manufactured housing present on the surrounding acreage. The market is modest in scale and generally owner-occupied, serving local families and workers tied to the Beaumont–Port Arthur economy. Rural parcels at the town's edges offer more space for those seeking a country setting.

Sour Lake is experienced as a single community rather than distinct neighborhoods, with a compact center of homes, churches, and businesses along its main streets. The old springs area and the oil-era development both left their mark on the town's layout. The edges of the city give way quickly to the piney woods and rural land of Hardin County. Its scale is intimate, and the town's historic identity is reflected in its surviving landmarks.

Life in Sour Lake is quiet and small-town, set within the larger Beaumont–Port Arthur region. Community life centers on schools, churches, and local events, and the town's history — both the mineral springs and the oil boom — remains a source of local pride. Beaumont, within driving distance, provides employment, shopping, medical care, and entertainment, while Sour Lake itself offers a slower, close-knit pace in the Southeast Texas piney woods.

Sour Lake is served by the Hardin-Jefferson Independent School District, which educates students from the city and the surrounding area. The district is a central part of community life, with school activities and athletics drawing broad participation, and it serves a wide swath of Hardin and Jefferson counties. Nearby Beaumont and the surrounding region offer additional educational and higher-education options.

Sour Lake sits along a state highway corridor in Hardin County, connecting the city to Beaumont and the Beaumont–Port Arthur metropolitan area. The region's U.S. highways and interstate network are within reach, tying the area to Houston and the Golden Triangle. Personal vehicles are essential, and the town has no fixed-route transit. The surrounding roads serve the piney woods and rural communities of the county.

Recreation in Sour Lake draws on the town's history and the surrounding Southeast Texas landscape. The area's oil heritage is preserved in local museums and historical sites, and the nearby forests, lakes, and the Big Thicket preserve area offer fishing, hunting, and outdoor activities within reach. Community life centers on school athletics and local parks. Beaumont and the Golden Triangle add cultural and recreational amenities nearby.
