Jamacha is a largely residential neighborhood, with mostly single-family houses, mixed with some multi-family development, Townhomes, and two apartment complexes. There is also some small-scale commercial development in the neighborhood on Imperial Ave, Lisbon St., 69th St., and the corner of Cardiff St. and Jamacha Rd. ==Geography==

The Skyline-Paradise Hills Community as a whole make up approximately 4,500 acres. The Jamacha consists predominantly of low-density single-family homes spread across the hilly area. The major geographic features are the Jamacha Valley that runs on an east-west axis in the community and give rise to Chollas Creek that flows into San Diego Bay. The San Diego Natural History Museum published geologic mapping indicates that Jamacha is underlain by both the Pliocene-age San Diego Formation and the Eocene-age Mission Valley Formation. Both of these formations are known to be rich in fossils and have produced important paleontological resources, and it has been determined that there are 12 recorded fossil collections within a one-mile radius of Jamacha. ==Demographics==
