Rancho Penasquitos is a master-planned community within the City of San Diego. Located south of Rancho Bernardo, west of I-15 and north of the Los Penasquitos Canyon Preserve, Rancho Penasquitos residents appreciate its easy access to the rest of the county. The area is approximately 10,000 acres including Black Mountain Regional Park with 51 percent designated for residential development; 34 percent is designated for parks and open space; two percent is designated for commercial space. Black Mountain is the area's most visible landmark, rising to 1,500 feet above the region. The hills and canyons separate the area from the rest of the city and make it seem more countrylike than urban.
Homes are built on the mesas and hills and the majority are typical middle class suburban homes although some custom homes do exist in the area. Many homes have views. There are a few condominiums and townhomes. The neighborhoods are quiet, well-maintained with many families with kids.
