Buying a condo in San Francisco is less about the unit than the building behind it. As of Q3 2026, the citywide median residential close price is $1.75M over the past year, near $1,193 per square foot (MLS). The figure that catches buyers, though, is the health of the homeowners association, which becomes your responsibility the day you close.
Unless otherwise noted, all market figures in this guide are from MLS data. Most buyers I work with start by comparing list prices, and that is the wrong first move. Two condos at the same price per square foot can carry very different monthly costs and very different resale prospects once you look at the association behind each one. One building runs lean and well-funded. The next has thin reserves, a special assessment on the horizon, and a financing problem that will follow you to resale. The list price does not tell you which is which.
I'm Chris Chour, founder and broker of EON Real Estate, and most of my work is single-family and condo transactions in San Francisco's higher-priced neighborhoods. The question I get most from first-time condo buyers is some version of "is this a good price?" The honest answer is that price is the easy part. What actually separates a clean purchase from a painful one is a short list of building-level checks that never show up in the photos. This guide walks through those checks in the order they matter, then grounds them in what the current market is doing.
How buying a condo in San Francisco actually works
A condo purchase in San Francisco is really two purchases stacked together. You buy the interior of your unit, and you buy a share of a homeowners association that owns everything else: the roof, the elevators, the lobby, the plumbing risers, the seismic structure. Your monthly HOA dues fund that shared ownership, and the association's finances become your finances the day you close.
That structure is why the same dollar figure can mean two very different deals. When a condo lists, the price reflects the interior. The building behind it can be strong or fragile, and only the disclosure package tells you which. So the sequence I recommend runs building first, then unit, then price. Buyers who reverse that order fall in love with a kitchen and inherit a reserve shortfall.
The building also changes how you finance the purchase. When a lender writes a loan on a house, it underwrites you and the property. When it writes a loan on a condo, it underwrites you and the unit alongside the association. Lenders assess whether a project meets their guidelines on owner-occupancy levels, reserve funding, single-entity ownership concentration, commercial space, along with any active litigation. A building that clears those tests is what the industry calls warrantable, and it qualifies for standard financing at standard rates. A building that fails one of them is non-warrantable, which can shrink your lender options, raise your rate, or push you toward a larger down payment. None of that is visible from the listing. All of it is knowable before you write an offer.
The last piece is the tax and carrying cost. A condo is assessed and taxed the same way a single-family home is: annual property tax on the assessed value, reassessed when you buy. I break the mechanics down in how San Francisco property tax works, and the short version for budgeting is that your true monthly cost is the mortgage plus property tax plus HOA dues plus insurance. The mortgage is usually the number buyers anchor to. The other three quietly reshape what you can actually afford.
The decision tree: what to check before you write an offer
Every condo we help a buyer evaluate runs through the same four questions. Work them in this order, because a failure high on the list can end the conversation before price ever matters.
1. Is the HOA financially healthy?
Start with the association's budget, reserve study, plus its current reserve balance. A well-run building funds its reserves so that a new roof or an elevator modernization is already planned and paid into, not billed to owners as a surprise. A special assessment is a one-time charge the association levies on top of regular dues to cover a shortfall, and it can range from modest to substantial per unit. The disclosure package should show you the reserve level, the planned major projects, and the history of dues increases. Thin reserves plus deferred maintenance is the combination that produces a special assessment, and you want to know that before you own a share of the bill.
2. Will the building finance cleanly?
Ask your lender to review the project early, not after your offer is accepted. This is where warrantability lives. If the building carries a high share of renters, a single owner controls many units, reserves are underfunded, or a lawsuit is pending, your loan terms can change or your lender can walk. A cash buyer can look past this. A financed buyer cannot, and finding out during escrow is the expensive way to learn it.
3. Is there disclosed litigation?
Recent listings in a building sometimes disclose HOA litigation, which affects both lender warrantability and price. Do not treat a disclosure as a verdict on the building, and do not assume the absence of a disclosure is a guarantee. Confirm the building's current litigation and warrantability status with your lender before you write, because it can change your financing and your negotiating position at the table.
4. Condo, TIC, or co-op?
San Francisco sells several forms of shared ownership, and they are not interchangeable. A true condominium gives you a deeded, separately financed unit. A TIC, or tenancy in common, is a shared deed where co-owners hold fractional interests, often on a single shared or fractional loan, which trades a lower purchase price for more financing and partnership complexity. A co-op means you own shares in a corporation that owns the building rather than the unit itself. Each carries a different financing path and a different resale pool. Make sure you know which one you are actually buying, because the sign out front says condo far more often than the title does.
San Francisco by the numbers
Here is the citywide backdrop every condo purchase sits inside. These are all-of-San-Francisco residential figures from the trailing 12 months, so treat them as the market's center of gravity rather than a condo-specific price. Condo pricing lands within this picture and swings widely by building, floor, view, and parking.
The San Francisco market in 2026
Read those two speed numbers together. A 12-day median days on market against a 16-day average tells you the middle of the market is moving quickly, while a slower tail pulls the average up. For a condo buyer, that means well-priced, cleanly financeable units go fast, and the ones that sit are usually sitting for a reason worth understanding: a pricing gap, a building issue, or a discounted floor plan. The $1,193 average price per square foot is the figure to sanity-check a specific unit against, because condos trade on price per square foot more cleanly than houses do. To turn that into a number for a building you are considering, multiply the building's own price per square foot by the interior size, then add the monthly HOA dues and property tax to reach a real cost of ownership. We can run that math on any specific listing.
What to consider before buying a San Francisco condo
This is the part I do not sugarcoat. A condo can be the right move and still carry tradeoffs a house does not, and naming them upfront is how you avoid a surprise later.
HOA dues rise, and they rise on someone else's schedule. Your mortgage payment is fixed. Your dues are not. An association can raise dues or levy a special assessment to fund a project you had no vote in timing. A building rich with amenities carries higher dues to pay for them, while a building with thin reserves carries the risk of a sudden assessment. Underwrite the dues trend, not just today's figure.
Warrantability can shrink your buyer pool at resale. The financing test that matters to you also matters to whoever buys from you later. A building that becomes non-warrantable is harder for the next buyer to finance, which narrows demand and can weigh on price. The tradeoff I flag most often is a lower entry price on a fragile building against a cleaner, more liquid resale on a well-run one.
Condos and houses appreciate differently. San Francisco's single-family homes and its condos do not always appreciate in step. That is not a reason to avoid condos. It is a reason to buy the building and the location with your eyes open on the carrying cost, rather than assuming a condo will track a house dollar for dollar.
How much does a condo cost in San Francisco in 2026?
As of Q3 2026, San Francisco's citywide median residential close price is $1.75M and the average is $2.18M, at about $1,193 per square foot over the trailing 12 months (MLS). Those are all-residential figures, so a condo can sit meaningfully below the median or well above it depending on the building, floor, view, and parking. The honest way to price a specific unit is to comp it against recent sales in that same building and size range.
How fast do San Francisco homes sell right now?
As of the trailing 12 months in 2026, the median San Francisco home closes in 12 days, with an average of 16 days on market (MLS). That pace tells a condo buyer that well-priced, cleanly financeable units clear quickly, so pre-approval and an early lender review of the building let you move without hesitating. Units that linger past the average usually carry a reason worth finding first.
Is a condo a good first purchase in San Francisco?
For many first-time buyers in 2026, a condo is the realistic entry point into a market whose citywide median residential price is $1.75M (MLS), because condos often price below single-family homes and shift maintenance to the association. The tradeoff is the HOA: lower upkeep effort, but dues and building risk you do not control. It is a good first purchase when the building is financially healthy and warrantable, and a costly one when it is not.
What should I check before buying a San Francisco condo?
Before writing an offer in 2026, check three things in order: the HOA's reserves, the building's lender warrantability, and any disclosed litigation. Read the reserve study, have your lender review the project early, and confirm the litigation status in writing. Only after those clear should price and unit condition drive your decision, because a building problem can undo an otherwise great price.
Should I buy a condo or a single-family home in San Francisco?
As of 2026, with a citywide median residential close price of $1.75M (MLS), the choice comes down to budget, effort, and control. A condo usually costs less at entry and hands maintenance to the association, at the price of shared decisions and dues you cannot fix. A house costs more and demands your own upkeep, but you control it fully. Reading the map of San Francisco neighborhoods helps match the choice to an area.
How competitive is the San Francisco market for buyers in 2026?
As of the trailing 12 months in 2026, homes are closing in a median of 12 days across roughly 1,000 residential sales in the sample window (MLS), a quick pace that rewards preparation. For condo buyers specifically, the competition concentrates on the clean, warrantable buildings. Getting your lender ahead of the building review is the edge, whether you are weighing a unit in Mission Bay or anywhere else in the city.
Talk to me about buying a condo
When you are ready to look at a specific building, I can pull the building-level comps, flag the warrantability and reserve questions worth asking, and tell you what a fair price looks like against recent sales in that same building. An hour on the disclosure package before an offer beats cleaning up a surprise during escrow. No pressure, and no obligation to list or buy anything to have that conversation.
