How San Diego's Hidden Homeownership Costs Compare to Other Major Cities — And Where We Actually Save Money

By Hedda ParashosSeptember 13, 2026

San Diego homeowners often assume they pay more than everyone else on every line item. A San Diego Union-Tribune study shows that's not the full picture — especially on utilities. Here's where San Diego holds its own, and where costs do run high.

San Diego homeowners pay less for electricity than residents in most major U.S. metros. The median electricity bill runs $1,918 per year in San Diego County, according to a San Diego Union-Tribune cost study — a number that surprises most people who assume every homeownership expense here runs above average. Understanding how San Diego's hidden homeownership costs compare to other major cities helps buyers price a purchase more accurately and helps current homeowners benchmark what they're spending.

Where San Diego Homeowners Actually Spend Less

Electricity is the clearest example. At $1,918 annually, San Diego County's median sits below what homeowners pay in cities like Phoenix, Houston, and Atlanta, where summer cooling loads push bills far higher. San Diego's climate does real work here: moderate temperatures mean air conditioning runs less, and that matters across a 12-month average.

Water costs also tend to be lower than in metros that face older infrastructure problems or drought surcharges at higher rates. And because San Diego lacks the freeze-thaw cycles common in Chicago, Boston, or New York, homeowners here typically spend less on annual maintenance items like pipe repairs, roof patching from ice damage, and foundation work tied to frost heave.

For buyers exploring La Jolla or coastal communities farther north, these utility and maintenance advantages can meaningfully offset what looks like a high purchase price on paper.

Where San Diego Costs Do Run Higher

Insurance is the honest counterpoint. Wildfire risk has pushed homeowners insurance premiums up across San Diego County, and some carriers have pulled back from the California market entirely. Buyers need to budget carefully and shop early — getting a quote before making an offer is a good habit, not an afterthought.

Property taxes follow Proposition 13 rules, so the rate itself (roughly 1.1% to 1.25% of assessed value) isn't out of line with other states. But because San Diego home values are high, the dollar amount on a tax bill for a $1.5 million La Jolla property is substantial in absolute terms. That's a distinction worth keeping clear: the rate is average, the base is not.

Homeowners who have held property here for years may find their assessed value is well below current market, which is one reason equity positions are strong for long-term owners. Find out what your home is worth →

What This Means For You

• Budget electricity at roughly $160 per month as a San Diego baseline — lower than many comparable metros.

• Get an insurance quote before finalizing any offer. Premiums vary significantly by ZIP code and proximity to fire-risk zones.

• On a tax bill, focus on the assessed value, not just the rate. New buyers pay taxes on the purchase price; long-term owners pay on a much lower assessed base.

• When comparing San Diego to other cities on total cost of ownership, include maintenance savings from the mild climate — that number adds up over five to ten years of ownership.

San Diego homeownership costs more upfront than most U.S. cities. But the full cost picture is more nuanced than the sticker price suggests. For buyers running the numbers on a purchase, or homeowners deciding whether to stay or sell, the utility and maintenance advantages are real inputs worth including in that math.

Frequently Asked Questions

Is San Diego's electricity cost really lower than other major cities?

Yes, based on the San Diego Union-Tribune study, the median electricity cost for San Diego County homeowners is $1,918 per year. That figure falls below what homeowners pay in high-cooling-demand cities like Phoenix or Houston, where summer air conditioning runs much longer.

How do San Diego property taxes compare to other states?

California's effective property tax rate, around 1.1% to 1.25% of assessed value, is not unusually high compared to states like New Jersey or Illinois. The difference in San Diego is that assessed values are high, so buyers at today's prices will pay a larger dollar amount than the rate alone implies. Long-term owners benefit from Proposition 13 limits on annual increases.

What homeownership costs should San Diego buyers budget for that often get overlooked?

Homeowners insurance is the most commonly underestimated line item right now, particularly for properties in or near wildfire-risk zones. HOA fees in coastal communities can also be substantial. Both costs vary enough by property and location that buyers should get actual quotes during escrow rather than relying on general estimates.
