Market Notes, Issue #22: What a Bedroom Costs | Level Up Market Intel with David Juarez

Here is how people actually shop. The first decision anyone makes is a number in a dropdown. A couple picks two. A family picks three. A family that means to stay picks four. Nobody says out loud what that number costs, and the filter certainly does not tell them. So this issue prices every rung, and then it presses on the part that decides whether you overpay. Freeze the floor area, add a bedroom, and does the market pay you back for it?

The short version, built on 4,804 closed sales from the last 12 months: a third bedroom in a house runs about $469,000 and a fourth about $831,000. Very little of that money is the room. You are buying the floor area it sits on.

How much does a 2, 3 or 4 bedroom house cost in San Francisco?

Take the 12 months that ended September 1, 2026. A two-bedroom single-family house closed at a median $1,400,000 across 485 sales. Three bedrooms: $1,869,000 on 894. Four: $2,700,000 on 607. The five-plus group is smaller and far less uniform, running from in-law warrens in the Excelsior to Pacific Heights mansions, and it landed at a median near $3,305,000 on 264 sales.

Now read that as steps rather than levels. Going from two bedrooms to three costs $469,000, a 33.5% climb. Going from three to four costs $831,000, a 44.5% climb and nearly twice the previous step in dollars. The rungs are not evenly spaced. They spread out the higher you go.

The bedroom ladder: median sold price by bedroom count Closed sales September 2, 2025 through September 1, 2026. The step between rungs is computed from the exact medians before rounding. Houses with five or more bedrooms and condos with four are shown for scale. San Francisco MLS via POTM Command.

How much does a 1, 2 or 3 bedroom condo cost?

Condo country has its own ladder, and the steep rung comes early. The second bedroom is a $620,000 move and an 85% climb, which reads that dramatic mainly because the bottom rung sits so low. Prices in order: $730,000 at one bedroom on 823 sales, $1,350,000 at two on 1,089, $1,900,000 at three on 507, and $2,525,000 at four on a thin 74. After the second, the steps shorten, $550,000 for the third and roughly $625,000 for the fourth.

The corridor makes the same point with a harder edge. Across SoMa, South Beach, Mission Bay, Yerba Buena and Van Ness/Civic Center, the median one-bedroom closed at $702,500 on 338 sales and the median two-bedroom at $1,350,000 on 329. Call that $647,500 for one more room.

Are you buying a bedroom or buying square feet?

One number rearranges everything above it. Put the three rungs on a per-foot basis and they collapse into each other. Two-bedroom houses: $1,132 per square foot. Three-bedroom: $1,125. Four-bedroom: $1,138. What separates the rungs is not price at all, it is floor area, at median sizes of 1,214, 1,710 and 2,412 square feet. My read is that nobody here is buying a bedroom. They are buying roughly $1,130 a foot of house, and the bedroom count is the shorthand a listing uses for how much of it there is.

So here is the test worth running. Among homes of the same size, what did the buyer pay for the one carrying an extra bedroom?

Same square feet, one more bedroom Median sold price by bedroom count inside each size band, houses above and condos below, same 12 months. A slice under 10 sales is not plotted. The reading at right is the step from the middle bedroom count to the next one up, except where noted. San Francisco MLS via POTM Command.

Houses give an answer that is hard to hear if you have ever framed a wall to make a bedroom. In the 1,000 to 1,400 square foot band, two bedrooms and three brought the same money, $1,370,000 and $1,369,000. Above 1,400 square feet the three-bedroom becomes the sweet spot, and the four-bedroom of identical size sold for less. At 1,400 to 1,800 square feet it was $1,610,000 against $1,759,000. At 1,800 to 2,200, $2,050,000 against $2,160,000. At 2,200 to 2,800, $2,850,000 against $3,000,000. Those four-bedroom medians rest on 59, 137 and 197 sales. Put four bedrooms inside 1,600 square feet and you own four small rooms, and buyers pay for rooms they can live in.

Condos invert that, though only at one rung. There the second bedroom pays for itself with size held constant: +$142,500 in the 700 to 1,000 square foot band and +$370,000 from 1,000 to 1,300, on 372 and 178 sales in the smaller band and 82 and 437 in the larger. The reason is buyer pool. A one-bedroom at 1,100 square feet and a two-bedroom at 1,100 square feet are two different products shown to two different pools, and the second pool is far deeper. The third bedroom is a different story. It adds nothing between 1,000 and 1,300 square feet, $42,500 between 1,300 and 1,700, and only starts earning its keep, about $152,500, above 1,700.

Which districts charge the most for a third bedroom?

Nothing in this issue moves the price of a third bedroom more than location does. The low end is $88,000 in District 10, Bayview and the Excelsior, where the stock is uniform and the extra room is usually a basement conversion. The high end is $579,000 in District 5, Noe, the Castro and the Haight, with District 7 near $1.5 million, where the two-bedroom house is so rare the rung is not rated. The Sunset, District 2, stays close to flat: $251,000 for the third bedroom and $343,000 for the fourth, on 104, 187 and 96 sales. The Richmond, District 1, charges more than twice as much at the same two steps. Every cell, with its sample size and reliability, sits in By the numbers.

Does the bedroom count change how fast a home sells?

The clock does not care how many bedrooms a house has. Whether it was two, three or four, the median sale went in 12 days, and between 82% and 87% of each group closed above asking. The exception sits at the very top: five bedrooms or more slows to 14 days and 63.6% over asking, because that is where buyers negotiate instead of bidding.

Condos behave differently, and the break comes at the second bedroom. One-bedrooms took a median 29 days with 35.1% closing over asking. Two-bedrooms took 15 days with 52.0% over. Three-bedrooms, 13 days and 64.7%. Set that next to the premium the second bedroom earned and it is one finding seen from two sides: the one-bedroom condo is the softest, slowest product on these pages.

This year the rungs pulled apart

A year ago the same window produced a flatter ladder. Every rung moved up, but not by the same amount, and the size of the gain tracked the size of the house. Two bedrooms: $1,300,000 to $1,400,000, up 7.7%. Three: about $1,611,000 to $1,869,000, up 16.0%. Four: $2,247,000 to $2,700,000, up 20.2%. That is the house-market heat this series has followed since Issue #13, arriving here as daylight between the rungs. Condos barely participated, one-bedrooms up 3.2% to $730,000 and two-bedrooms up 8.1% to $1,350,000.

What I would do with it

Buyers, start somewhere other than the dropdown. Sort by square footage and by neighborhood, walk the floor plan, and let the bedroom count be a filter rather than the thing you are paying for. A well-laid-out three-bedroom at 1,700 square feet beats a chopped-up four-bedroom at 1,700 square feet on price, on light and on resale, and the closed sales already say so. Condo country is the one place that math turns over. If a two-bedroom is within reach, that room holds its value and sells in roughly half the time, and my recommendation is to stretch for it.

Sellers with a house: leave the walls alone. Converting the dining room produces a four-bedroom that sells like a three-bedroom of the same size, minus a dining room. Put that budget into the rooms you already have. Sellers with a one-bedroom condo have a different job. Price for a 29-day market and for a buyer pool that mostly will not go above asking, then lead with square footage and outdoor space, because those are what you are being weighed against by buyers who would rather have the second bedroom.

None of this replaces the work on your own street. Pull your bedroom count in your own neighborhood before a budget or a list price gets set. A citywide ladder is a map, and a map is not the ground. No two properties are alike.

Frequently asked questions

How much does a 3 bedroom house cost in San Francisco?

$1,869,000 is the median, drawn from 894 sales in the 12 months ending September 1, 2026, at a typical 1,710 square feet. Where you look changes it: District 10, Bayview and the Excelsior, sits at $1,123,000, while District 7, the Marina and Pacific Heights, sits at $4,215,000.

How much more does a 4 bedroom house cost than a 3 bedroom?

Roughly $831,000 more, a 44% step: $2,700,000 against $1,869,000 at the citywide median. Size explains most of it, since a median four-bedroom measures 2,412 square feet and a median three-bedroom 1,710. Hold the size constant and the step reverses. In every band above 1,400 square feet, a four-bedroom house sold for less than a three-bedroom.

How much does a 2 bedroom condo cost in San Francisco?

$1,350,000 was the median across 1,089 sales in the 12 months ending September 1, 2026, at a typical size of 1,232 square feet. For context on either side of it: one bedroom at $730,000, three bedrooms at $1,900,000.

Does adding a bedroom increase home value in San Francisco?

Only when it brings square footage with it or genuinely improves the plan. Houses at two, three and four bedrooms all traded near $1,130 per square foot, and a fourth bedroom carved out of that same footage sold $110,000 to $150,000 below a three-bedroom of matching size. Condos are the exception at the second bedroom, worth $142,500 to $370,000 at equal size, while the third adds little until about 1,700 square feet.

Which sells faster, a 1 bedroom or a 2 bedroom condo?

The two-bedroom, by a wide margin. Its median sale took 15 days, with 52% closing over asking. A one-bedroom needed 29 days, and only 35% got above the asking price. Every house in the study, whatever its bedroom count, went in a median 12 days over the same 12 months.

AI Corridor Scoreboard

The softest corner of the city gets one reading in every issue. These are the condos near the new AI offices, tracked here so the turn is visible while it is happening rather than afterward.

Issue	Date	Reading	Call
#22 (this issue)	Sep 2, 2026	The steepest second bedroom in the city. Corridor one-bedrooms sold at a median $702,500 and two-bedrooms at $1,350,000 over the last 12 months, a $647,500 step on 338 and 329 sales, with both rungs still at or just under asking (99.7% and 99.6%) in 34 and 23 median days.	The corridor still negotiates, and the one-bedroom negotiates longest.
#21	Aug 30, 2026	Still the calm end of the map. South Beach at asking on 167 sales with 29.9% over; SoMa, Mission Bay and Van Ness / Civic Center at asking; Yerba Buena 1.7% below. Meanwhile 56.6% of condos citywide now clear asking, up from 36.4% a year ago.	The negotiator's end of the market, with the floor rising underneath it.

Show the 18 earlier readings

Issue	Date	Reading	Call
#20	Aug 25, 2026	Two markets, one label. Corridor towers still at or below asking over the past six months (South Beach at asking on 168 sales, Yerba Buena -2.2%) while low-dues flats citywide cleared 10%+ over in 59.9% of sales.	Check the dues before you plan the offer.
#19	Aug 18, 2026	Where cash buys the most and shouts the least. Corridor condos ran 41.7% cash in the past 12 months, the heaviest concentration this series tracks, yet cash and financed closed at the same price, 99.2% versus 99.3% of asking. Cash's whole edge here is the clock: 20 median days on market against 39 financed.	Financed buyers give up nothing on price here; they pay in patience.
#17	Aug 9, 2026	Zero, which is the cleanest reading this scoreboard has produced. Across 368 corridor condo closings so far in 2026, not one sold $1,000,000 over asking, and the typical one closed slightly under asking: South Beach 0.7% below on 183 sales, South of Market 1.0% below on 79, Yerba Buena 2.4% below on 53, Mission Bay exactly at asking on 53. In an issue about where the overbidding is, the corridor is where it is not.	Buyer opening holds, and this issue measures exactly how wide it is.
#16	Aug 6, 2026	Flat in every window, which this issue argues is the whole point. South Beach condos read 100.0% of asking at 30, 90 and 180 days and 99.0% over the trailing year. South of Market reads 99.4, 99.8, 99.6 and 99.0. Four windows, one answer. Every house lane in this issue moved when the window moved; the corridor did not, and a segment that reads the same no matter how you slice it is a segment that is not turning.	Buyer opening holds, and now it is measured four ways instead of one.
#15	Aug 2, 2026	Unchanged at the bottom of the same ladder. This issue extended the over-asking gradient into small multifamily, and the corridor still anchors the low end: right at asking, while two-unit buildings cleared 11.7% over and houses 23.8%. The ordering is by how much a property lives like a house, and a corridor tower is the furthest thing from one.	Buyer opening holds, and this issue explains why it persists.
#14	Jul 29, 2026	Read on supply this time, not price. Citywide condo and townhome months of supply fell from 3.9 to 1.7 in a year and active listings from 772 to 480, so even the calmest lane in the city now offers less to choose from. This issue did not re-measure corridor pricing.	Buyer opening holds on price; the shelf behind it is thinner.
#13	Jul 25, 2026	Graduated to the essay. Back at asking for the first time since 2022, after three springs about 1% below it, and the clock changed: median market time fell from 38 days to 19 and the share selling over asking roughly doubled, from the low twenties to the mid forties. Price at par, speed doubled.	Negotiating room intact; the window now narrows in speed, not price.
#12	Jul 21, 2026	Still the calm corner, and it proves the point. District 9 condos, SoMa, Mission Bay, and South Beach, sold right at list, about 100%, with only 31% over asking on 836 sales, while mid-priced houses cleared 123 to 127% of list. Condos rarely get listed low to start a war, so the overbid never appears.	Buyer leverage holds where the list-low tactic is not used.
#11	Jul 17, 2026	Unmoved by the house story. While overbidding ran one tier below the trophy core, the corridor and condo core cleared near asking, and the two flat lanes the field named as spillover candidates, Hayes Valley and Lower Pacific Heights, stayed calm in closed data.	Still the clearest buyer opening in the city.
#10	Jul 14, 2026	Still soft while the headline is elsewhere. June's million-over-asking story is a west-side and central house market, not the AI-corridor towers. District 9 condos, SoMa, Mission Bay and South Beach, ran about 10% below last year even as volume climbed. Activity returns to the corridor; pricing has not.	Still the clearest buyer opening in the city.
#09	Jul 10, 2026	Still the soft floor at the halfway mark. District 9 condos, SoMa, Mission Bay, and South Beach, sold near 100% of list with only about 36% over asking on roughly 290 sales this year, while citywide houses ran near 121% of list. The widest lane in the city stays open.	Clearest buyer opportunity holds into the second half.
#08	Jul 5, 2026	Still the soft floor even as the top books records. District 9 condos, SoMa, Mission Bay, and South Beach, sold near 100% of list with heavy cash and light competition, while $5M+ houses set a decade volume record at about 112% of list on roughly 64% cash. Cash without a crowd here.	Buyer opportunity intact where the crowds are not.
#06	Jun 25, 2026	Still the calm corner while the house middle runs hot. District 9 condos, SoMa, Mission Bay, and South Beach, sold right at list, about 100%, with only 35% over asking on 300 sales, against the $1.5M to $3M house band at 122 to 125% of list.	Buyer opportunity holds where the bidding wars are not.
#05	Jun 21, 2026	Cash, not heat. Corridor condos carry heavier cash than the citywide condo average, about 42% versus 37%, yet still sell near 98.7% of list with only about 20% over asking versus 45% citywide. Cash concentrates here; competition does not.	Negotiating room for financed buyers.
#04	Jun 17, 2026	Still the soft floor while houses raced ahead. Corridor near 98 to 99% of list versus 103.8% citywide and about 123% for single-family in the last 30 days.	Buyer opportunity holds; the gap to houses only widened.
#03	Jun 13, 2026	Still the bottom of the overbid table. Corridor sale-to-list at about 98 to 99% versus 103.6% citywide, trailing year.	Opportunity intact for negotiators.
#02	Jun 10, 2026	Turning at the edges. Citywide condos hit 101.4% of list in May; inventory fell to 584 from 905. The corridor towers remain the soft end.	Window narrowing, not closed.
#01	Jun 7, 2026	Soft. Only 37 to 43% of SoMa, Mission Bay, and downtown condos sold over asking.	Clearest buyer opportunity in the city.

Takeaways

Stepping up a house costs about $469,000 for the third bedroom and close to double that, $831,000, for the fourth. Exact medians over the last 12 months: houses at $1,400,000, $1,869,000, $2,700,000 and $3,305,000 for two, three, four and five-plus bedrooms; condos at $730,000, $1,350,000 and $1,900,000 for one, two and three.
What you are climbing is a size ladder. Median houses run 1,214, 1,710 and 2,412 square feet at two, three and four bedrooms. Per foot the three rungs are indistinguishable, at $1,132, $1,125 and $1,138, or about $1,130 whichever one you pick.
Hold size constant and a fourth bedroom becomes a markdown rather than a premium. From 1,400 square feet up, the three-bedroom wins every band: $1.76M against $1.61M between 1,400 and 1,800 square feet, $3.00M against $2.85M between 2,200 and 2,800.
Condos break that rule once, at the second bedroom, which earns its price with size held still: +$142,500 in the 700 to 1,000 square foot band, +$370,000 from 1,000 to 1,300. A third brings nothing until roughly 1,700 square feet. The one-bedroom is also the slow lane, 29 median days and 35% over asking against 15 days and 52% for two bedrooms.
Geography sets the price of that third bedroom: +$88,000 in District 10, +$579,000 in District 5, about +$1.5M in District 7. The rungs also spread this year. Two-bedroom houses gained 7.7%, three-bedrooms 16.0%, four-bedrooms 20.2%. Bigger home, bigger gain.

Every San Francisco neighborhood carries its own median price, sale-to-list and market time, filterable by bedroom count, inside the market explorer. Run yours before you settle on a budget or a list price.

Methodology and sources

Source: POTM Command, governed MLS analytics, September 1, 2026 data, 62,689 governed closed sales since 2016. This issue reads closed sales from September 2, 2025 through September 1, 2026: 2,303 single-family houses and 2,501 condominiums and townhouses, every one with a reported bedroom count. Year-over-year figures use the identical window one year earlier. Every figure is an exact median, never an average; the step between rungs is computed from the exact medians before rounding. Bedroom counts are as reported to the MLS; a legal bedroom, a den and a converted garage room are whatever the listing agent called them, and square footage is as reported, missing on about 6% of sales, which the size bands exclude. Price per square foot is the median of each sale's own ratio. District medians at 20 or more sales are Strong, 10 to 19 Directional, under 10 not rated; the tables say which. Tenancy in common and 2-4 unit buildings are excluded throughout. General information, not a valuation of any specific home and not legal, lending or tax advice.
