Large lots along Highway 94
Jamul is an unincorporated part of San Diego's East County, around 16 miles from downtown San Diego in a straight line, with 6,179 residents in the 2020 Census. County land-use plans here are dominated by semi-rural residential and rural lands, with large lots of 10 to 80 acres and a few small village residential areas. State Route 94 (Campo Road) is the main road, Lyons Valley Road, Jamul Drive and Proctor Valley Road branch off it, and Otay Lakes, Jamul Creek and the Hollywood Casino at Jamul Indian Village are local landmarks.
Otay Water District
The Otay Water District lists Jamul among the communities in its service area of about 125 square miles in southeastern San Diego County. Otay's water is imported, bought from the Metropolitan Water District and the San Diego County Water Authority, with Helix Water District also listed as a supplier, and some desalinated seawater from the Carlsbad Desalination Plant reaches its system. Otay posts its annual water quality report on its website.
Backflow rules that reach homes
Otay requires an approved backflow assembly on every non-residential connection and on residential services it rates as low or high hazard. Single-family homes with fire sprinkler systems generally need an above-grade double check valve assembly unless specific criteria are met. Assemblies go on the customer's side of the service connection and must be tested at least once a year from the installation date, and again after any repair, replacement or relocation, by a District-approved certified tester at the owner's expense. Noncompliance can bring fines or a shutoff. Otay's Backflow Department is at (619) 670-2263.
Housing
The median Jamul home was built around 1985, and about 38.9 percent of units predate 1980. Water heater replacement, leak repair and supply line upgrades are common needs across both age groups.
Gas or propane
SDG&E is the gas and electric utility for the county, though some backcountry homes use propane or are all-electric. Smell natural gas? Get outside, then call 911 and SDG&E at 1-800-611-7343. If your home uses propane, leave and call 911 and your propane supplier.
Permits and sewer
Because Jamul is unincorporated, building, plumbing and water heater permits go through the County of San Diego Planning & Development Services. Jamul's sewer arrangements were not confirmed in our research, so confirm how your property's wastewater is handled before drain or sewer work.
How Jamul compares with San Diego
City of San Diego homes deal with the city for water, sewer, backflow and permits. Jamul deals with Otay for water and backflow and the County for permits, on much larger lots.
