Why this is common in San Diego
Because San Diego's water supply tends to run very hard, water heaters in the area can be more prone to sediment and scale accumulation inside the tank, which may reduce efficiency and shorten the unit's effective lifespan over time. This is compounded by the city's older housing stock, where original water heater installations in many homes may be nearing or beyond typical replacement age.
Together, hard water and aging equipment are common contributors to water heater problems in the area. California's water heater seismic strapping requirement (Health and Safety Code Section 19211, implemented locally via the California Plumbing Code) is a state-specific installation detail that doesn't exist in most other markets.
Paired with San Diego's very hard water and older housing stock, water heaters here may need both structural attention (strapping) and maintenance attention (sediment/scale buildup) less commonly seen together in newer-construction or softer-water regions.
What San Diego homeowners should know
San Diego's municipal water supply is classified as very hard, and much of the housing stock is older -- a combination that can mean both maintenance and structural attention for a water heater.
More detail
San Diego's municipal water supply is classified as very hard, generally in the 216-284 ppm range, largely due to the imported Colorado River water that supplies much of the region. Hard water can allow mineral sediment to settle and build up inside a water heater tank over time; enough buildup can insulate the tank from its heat source, reduce efficiency, and in some cases contribute to premature tank failure.
Combined with San Diego's older housing stock — many homes were built decades ago, with a median build year around 1979 — some water heaters may be due for inspection, flushing, or replacement sooner than homeowners expect. California also has a distinctive statewide requirement most other states don't: water heaters must be braced, anchored, or strapped to resist earthquake displacement, per California Health and Safety Code Section 19211 and the California Plumbing Code.
Homeowners considering a repair or replacement may want to ask their plumbing provider about both the water heater's age/condition and its current seismic strapping status.

What affects the cost in San Diego
Water heater repair costs in San Diego depend on what's failing. Common component repairs — a burnt-out heating element or thermostat, a faulty thermocouple, or a leaking temperature-and-pressure relief valve — typically run $150–$350 in parts and labor. If the tank itself has failed or is near the end of its service life, full replacement (a standard 40–50 gallon tank, installed) generally runs $1,200–$2,500, with tankless or high-efficiency units running higher.
