Pine Valley's housing is overwhelmingly single-family and low-density, with mountain cabins, ranch-style homes, and larger custom houses on generous, often forested lots. Many properties include acreage, horse facilities, or space for workshops and recreational vehicles, and the community's unincorporated, fire-prone setting shapes lot sizes and building practices. Inventory is scattered across rural roads rather than in dense subdivisions, and the area appeals to buyers seeking privacy, forest, and a true mountain lifestyle within commuting distance of San Diego.

Pine Valley is a dispersed mountain community rather than a grid of named neighborhoods. Homes spread across wooded parcels and rural roads centered roughly on the Interstate 8 corridor and the community's small commercial core, which includes the post office and district offices. The Mountain Empire region around it encompasses other backcountry settlements such as Descanso, Guatay, and Campo, giving the area a shared rural identity. Cleveland National Forest surrounds the community on all sides.

Life in Pine Valley is defined by its mountain setting and rural pace. Residents enjoy cool summers, snow on occasion in winter, and the quiet of the forest, with deer, oak woodland, and open sky as everyday neighbors. The community is self-sufficient and outdoors-oriented, with hiking, camping, and four-wheeling close at hand. Errands and employment often mean a drive down Interstate 8 toward El Cajon or San Diego, while the community itself stays low-key and neighborly, anchored by its school district and volunteer services.

Pine Valley is served by the Mountain Empire Unified School District, which is headquartered in the community and operates campuses across the Mountain Empire backcountry. The district includes Pine Valley Charter School among its options and serves students from Pine Valley east toward Campo and the border region. Because the district covers a large, sparsely populated area, students may travel significant distances, and families should confirm school assignments and transportation directly with the district.

Interstate 8 is Pine Valley's principal connection, linking the community west to El Cajon and downtown San Diego and east through the mountains toward El Centro and the Imperial Valley. State Route 79 branches off nearby toward Julian and the northern backcountry. There is no public transit within the community, so travel is entirely car-dependent, with commuters driving the freeway corridor for work, shopping, and services. The freeway's mountain grades and seasonal conditions are a practical consideration for residents.

Recreation in Pine Valley is centered on the Cleveland National Forest, which surrounds the community and offers extensive hiking, camping, and backcountry access, including portions of the Pacific Crest Trail in the nearby Laguna Mountains. The area's forest roads support off-highway riding and mountain biking, and nearby Lake Morena and the region's reservoirs add fishing and boating. The cooler mountain setting makes the community a year-round base for outdoor pursuits ranging from birdwatching to snow play in winter.
