How Much Does It Cost to Own a Home in San Diego?

When people ask how much it costs to own a home in San Diego, the conversation usually starts with home prices. That's understandable. In July 2026, the median home sale price across San Diego County was approximately $937,000, according to Redfin.

But purchase price and cost of ownership are two different things.

Once you own the property, your housing budget may include a mortgage payment, property taxes, homeowners insurance, utilities, maintenance and repairs, HOA dues, landscaping, and other property-specific expenses. Some arrive every month. Others might only appear once or twice a year—or unexpectedly several years down the road.

And there isn't one useful "average monthly cost" that applies to every San Diego homeowner. A condo in Mission Valley, an older detached home in Kensington or Talmadge, a coastal property, and a newer home in a planned community can have very different expenses even if two happen to sell for similar prices.

Here's what actually goes into the cost of owning a home in San Diego.

1. Your Mortgage Payment

For homeowners who finance their purchase, the mortgage will typically make up the largest portion of the recurring housing expense.

The payment depends on the purchase price, amount financed, down payment, interest rate, loan term and type of financing. Depending on the loan, mortgage insurance or other costs may also be part of the monthly payment.

That means two people purchasing homes for exactly the same price could have very different monthly mortgage payments.

Interest rates also change, which is why a monthly payment estimate found online today shouldn't be treated as a permanent benchmark for what a future San Diego buyer will pay. Buyers considering a purchase should work with a qualified mortgage professional to understand the financing options and costs that apply to their circumstances.

2. California Property Taxes

Property taxes are another significant piece of the ownership equation, and California's system deserves a little context.

Under Proposition 13, taxable real property is generally subject to a 1% property-tax rate based on taxable assessed value, plus amounts associated with voter-approved indebtedness. After a change in ownership, property is generally reassessed based on its market value at the time of the change, subject to applicable exclusions.

That does not mean every homeowner's total property-tax bill simply equals 1% of what they paid for the house. Additional taxes, assessments and direct charges may appear on a particular property's bill.

California can also issue a supplemental assessment after a qualifying change in ownership or completed new construction to account for the difference between the property's prior assessed value and its newly established value for the applicable portion of the fiscal year.

For a buyer, looking at the existing owner's tax bill alone may therefore provide an incomplete picture of what their own future property taxes could look like.

3. Homeowners Insurance

Homeowners insurance should also be evaluated for the specific property rather than estimated from a generic San Diego average.

Premiums and available coverage can vary based on the property, insurer, coverage selected, deductible, construction characteristics and other underwriting factors. Some properties may present different insurance considerations than others.

For buyers, that makes obtaining property-specific insurance information during the purchasing process particularly useful. A quote for one house isn't necessarily a good estimate for the house down the street.

The important budgeting lesson is simply to include insurance in the ownership calculation rather than focusing exclusively on principal and interest.

4. HOA Dues

San Diego has everything from detached homes without an association to condos, townhomes and planned communities with monthly HOA dues.

What those dues cover can differ substantially. Depending on the association, dues may contribute toward common-area maintenance, landscaping, amenities, building exteriors, certain utilities, insurance for common property, reserves, management or other shared expenses.

This is why comparing two properties based solely on their HOA amount can be misleading.

A detached home with no HOA may leave the homeowner individually responsible for expenses that an association handles collectively at another property. Conversely, a property with HOA dues adds a recurring expense that needs to fit into the homeowner's monthly budget.

Buyers should understand both how much the dues are and what they're paying for.

5. Electricity, Gas, Water and Other Utilities

Utilities are another category where averages only tell you so much.

The size and age of the home, number of occupants, appliances, heating and cooling systems, insulation, solar equipment, landscaping, electric vehicles, personal habits and even the property's location can influence usage.

Electricity costs can also depend on the applicable rate structure. SDG&E has residential time-of-use rate plans in which pricing varies depending on when electricity is consumed, and available plans and rates can change.

A larger inland property with significant cooling needs may therefore have a very different utility profile from a smaller coastal condo—even if both fall under the broad category of "living in San Diego."

6. Maintenance and Repairs

This is probably the easiest cost to forget because there isn't a maintenance bill waiting in your mailbox every month.

A home is made up of components with different lifespans. Roofs, water heaters, HVAC equipment, appliances, plumbing fixtures, exterior finishes, windows, electrical components and countless smaller items can eventually require maintenance, repair or replacement.

The cost won't be identical every year. One year may involve little beyond routine upkeep; another could bring a major repair.

The age and condition of the property matter as well. An older home in an established San Diego neighborhood may have different maintenance considerations from newer construction, while coastal exposure, landscaping, construction materials and previous improvements can create their own variables.

Rather than pretending there's one perfect maintenance percentage for every homeowner, it's more useful to recognize that maintenance is part of the cost of ownership even when nothing currently needs repair.

7. Landscaping and Exterior Upkeep

For detached homes in particular, the property doesn't stop at the front door.

Landscaping, irrigation systems, tree care, exterior painting, fencing, drainage, pest control and other outdoor maintenance can all become part of homeownership. A larger lot may create very different ongoing responsibilities from a townhome or condo with common-area maintenance.

This is another place where HOA and non-HOA properties can be difficult to compare at first glance. One homeowner may write a monthly check to an association while another pays individual vendors or handles maintenance themselves throughout the year.

Either way, those expenses are part of owning the property.

8. The Big Expenses That Don't Happen Every Month

Some of the most significant homeownership costs are the easiest to ignore precisely because they aren't monthly.

A roof may last for years before needing major attention. The same goes for a water heater, HVAC system, exterior work, major appliances or other components.

Those aren't reasons to be afraid of owning a home. They're simply part of understanding what ownership actually means.

A realistic homeownership budget therefore looks beyond what is due this month and leaves room for future expenses that may eventually arrive.

Why Two $900,000 San Diego Homes Can Cost Very Different Amounts to Own

This is where the numbers become much more useful.

Imagine two San Diego homes selling at roughly the same price. One is a condo with an HOA that handles exterior building maintenance and some common expenses. The other is a detached house without an HOA where the owner is responsible for the roof, exterior, landscaping and other maintenance.

Their purchase prices may look similar while their ongoing expenses are structured completely differently.

Or compare an older home in Kensington or Talmadge with newer construction elsewhere in the county. Even at comparable prices, property taxes and assessments, HOA obligations, utility characteristics, insurance costs, landscaping and maintenance expectations may differ.

That's why asking “What does this particular home cost to own?” is much more useful than asking for one average number for all of San Diego.

Look Beyond the Listing Price

San Diego homeownership isn't inexpensive, but understanding the full picture makes it much easier to compare properties realistically.

When evaluating a home, look beyond the mortgage payment. Consider the property's taxes and assessments, obtain insurance information, review HOA dues and what they cover, think about utilities, understand the major systems you're taking responsibility for, and leave room for routine maintenance and future repairs.

A listing price tells you what it may cost to buy the property.

Understanding everything else tells you what it may cost to own it.
