What a Bedroom Costs
Every search starts with a bedroom count, so here is the price of each rung: what a two, three and four bedroom home sold for over the last 12 months, in every district. Then the harder question. At the same square footage, is the extra bedroom worth anything at all?

Every home search in San Francisco begins the same way: a bedroom count typed into a filter. Two for a couple, three for a family, four for the family that intends to stay. So this issue answers the question the filter implies and nobody prices out loud. What does each bedroom cost? Then it asks the question that actually decides whether you overpay: at the same square footage, is the extra bedroom worth anything?
The short answer, from 4,804 closed sales over the last 12 months: the third bedroom in a house costs about $469,000 and the fourth about $831,000, and almost none of that money is the bedroom. It is the square feet the bedroom sits in.
How much does a 2, 3 or 4 bedroom house cost in San Francisco?
Over the 12 months ending September 1, 2026, the median two-bedroom single-family house sold for $1,400,000, the median three-bedroom for $1,869,000 and the median four-bedroom for $2,700,000, on 485, 894 and 607 sales. Five or more bedrooms, a smaller and stranger group that runs from Excelsior in-law warrens to Pacific Heights mansions, sold at a median of about $3,305,000 on 264 sales.
Read as steps: the third bedroom adds $469,000, a 33.5% climb. The fourth adds $831,000, a 44.5% climb, nearly twice the third in dollars. The ladder is not evenly spaced, and it gets steeper as you go up.
How much does a 1, 2 or 3 bedroom condo cost?
Condos and townhouses climb their own ladder from a lower first rung: $730,000 for one bedroom on 823 sales, $1,350,000 for two on 1,089 sales, $1,900,000 for three on 507, and $2,525,000 for four on a thin 74. The second bedroom is the big jump in condo country, $620,000 and an 85% climb, because the one-bedroom rung starts so low. The third adds $550,000, and the fourth about $625,000.
The corridor tells the same story in sharper relief. In SoMa, South Beach, Mission Bay, Yerba Buena and Van Ness/Civic Center, a one-bedroom sold at a median $702,500 and a two-bedroom at $1,350,000: the second bedroom there is a $647,500 step, on 338 and 329 sales.
Is the price the bedroom, or the square feet?
Here is the number that reorganizes the whole ladder. The median two-bedroom house sold for $1,132 per square foot. The median three-bedroom: $1,125. The median four-bedroom: $1,138. Three rungs of the ladder, one price per foot. What separates them is size: 1,214, 1,710 and 2,412 median square feet. Buyers are not paying for a bedroom. They are paying about $1,130 a foot for a bigger house, and the bedroom count is the shorthand the listing uses to say how big.
So we held the size fixed and asked the question directly. Inside each square-footage band, what did a home with one more bedroom sell for?
For houses, the answer is uncomfortable for anyone who has ever put up a wall to make a bedroom. At 1,000 to 1,400 square feet, two bedrooms and three sold for the same money, $1,370,000 and $1,369,000. From 1,400 square feet up, the three-bedroom is the sweet spot, and the four-bedroom of the same size sold for less: $1,610,000 against $1,759,000 at 1,400 to 1,800 square feet, $2,050,000 against $2,160,000 at 1,800 to 2,200, and $2,850,000 against $3,000,000 at 2,200 to 2,800, on 59, 137 and 197 four-bedroom sales. Four bedrooms in 1,600 square feet is four small rooms, and the market pays for the rooms it can live in.
Condos run the other way, but only for one bedroom. The second bedroom pays for itself even at the same size: +$142,500 at 700 to 1,000 square feet and +$370,000 at 1,000 to 1,300, on 372 and 178 sales at the smaller band and 82 and 437 at the larger. A 1,100-square-foot one-bedroom and a 1,100-square-foot two-bedroom are different products to the buyer pool, and the pool for the second one is much deeper. The third condo bedroom, though, adds nothing at 1,000 to 1,300 square feet, $42,500 at 1,300 to 1,700, and only earns its keep, about $152,500, above 1,700.
Where is the third bedroom cheapest, and where is it dearest?
The step from two bedrooms to three ranges from $88,000 in District 10, Bayview and the Excelsior, where the housing stock is uniform and the extra room is often a basement conversion, to $579,000 in District 5, Noe, the Castro and the Haight, and roughly $1.5 million in District 7, where the two-bedroom house barely exists and is not rated. The Sunset, District 2, is nearly as flat: $251,000 for the third bedroom and $343,000 for the fourth, on 104, 187 and 96 sales. The Richmond, District 1, is more than twice as steep at the same rungs. The full table is in By the numbers, with sample sizes and reliability on every cell.

Which bedroom count sells fastest?
For houses, none of it matters to the clock: two, three and four bedroom houses all sold in a median 12 days, and 82% to 87% of each group sold over asking. The five-plus group is the one that slows, 14 days and 63.6% over asking, because the very top of the market negotiates.
Condos split at the second bedroom. The median one-bedroom took 29 days and 35.1% sold over asking. The median two-bedroom took 15 days and 52.0% sold over. The three-bedroom, 13 days and 64.7%. The one-bedroom condo is the slowest, softest product in this issue, which is the same fact as the second bedroom's premium seen from the other side.
The ladder got steeper this year
Against the identical window one year earlier, two-bedroom houses rose from $1,300,000 to $1,400,000, up 7.7%. Three-bedrooms rose from about $1,611,000 to $1,869,000, up 16.0%. Four-bedrooms rose from $2,247,000 to $2,700,000, up 20.2%. The bigger the house, the bigger the gain, which is the house-market heat this series has tracked since Issue #13 showing up as a widening gap between the rungs. Condos moved less: one-bedrooms up 3.2% to $730,000, two-bedrooms up 8.1% to $1,350,000.
How to use this
If you are buying: search by square footage and neighborhood, then judge the floor plan, and treat the bedroom count as a starting filter rather than the thing you are paying for. A well-laid 1,700-square-foot three-bedroom beats a chopped 1,700-square-foot four-bedroom on price, on light and on resale, and the market already prices it that way. In condo country the calculus flips once: if you can reach a two-bedroom, the second bedroom holds its value and sells in half the time, and that is worth stretching for.
If you are selling a house: do not add a wall to make a bedroom before listing. A converted dining room becomes a four-bedroom that sells like a three-bedroom of its size, minus the dining room. Spend the same money on the rooms you have. If you are selling a one-bedroom condo, price for a 29-day market and a buyer pool that mostly does not overbid, and make the square footage and the outdoor space the headline, because those are what the second-bedroom buyers are comparing you against.
And in every case, run your own bedroom count in your own neighborhood before you set a budget or a list price. The citywide ladder is a map. Your block is the territory.
Frequently asked questions

About $831,000 at the citywide median: $2,700,000 for four bedrooms against $1,869,000 for three, a 44% step. Most of that gap is size, since the median four-bedroom is 2,412 square feet against 1,710. At the same square footage, a four-bedroom house sold for less than a three-bedroom in every size band from 1,400 square feet up.
How much does a 2 bedroom condo cost in San Francisco?
The median two-bedroom condo or townhouse sold for $1,350,000 in the 12 months ending September 1, 2026, on 1,089 sales, at a median 1,232 square feet. A one-bedroom sold for $730,000 and a three-bedroom for $1,900,000.
Does adding a bedroom increase home value in San Francisco?
Only if it adds square footage or improves the floor plan. Two, three and four bedroom houses all sold at about $1,130 per square foot, and a fourth bedroom carved out of the same square footage sold for $110,000 to $150,000 less than a three-bedroom of the same size. In condos, a second bedroom did add value at the same size, $142,500 to $370,000, while a third added little below about 1,700 square feet.
Which sells faster, a 1 bedroom or a 2 bedroom condo?
Two bedrooms. Over the last 12 months the median one-bedroom condo took 29 days to sell and 35% sold over asking; the median two-bedroom took 15 days and 52% sold over asking. Houses of two, three and four bedrooms all sold in a median 12 days.

AI Corridor Scoreboard
One reading per issue on the city's softest segment, the condos near the new AI offices, so you can watch the turn as it happens.
| 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. |
- The ladder, last 12 months, exact medians: houses $1,400,000 with two bedrooms, $1,869,000 with three, $2,700,000 with four, $3,305,000 with five or more. Condos $730,000 with one, $1,350,000 with two, $1,900,000 with three. The third bedroom in a house adds about $469,000; the fourth adds about $831,000, nearly double.
- The money is square footage, not the bedroom: two, three and four bedroom houses all sell at about $1,130 per square foot ($1,132, $1,125, $1,138). Their median sizes are 1,214, 1,710 and 2,412 square feet, and that is the ladder you are actually climbing.
- At a fixed size, a fourth bedroom in a house is a discount, not a premium: $1.61M against $1.76M for three bedrooms at 1,400 to 1,800 square feet, and $2.85M against $3.00M at 2,200 to 2,800. A three-bedroom of the same size outsells it in every band from 1,400 square feet up.
- The exception is the second bedroom in a condo, which pays for itself even at the same size: +$142,500 at 700 to 1,000 square feet and +$370,000 at 1,000 to 1,300. The third condo bedroom adds nothing until about 1,700 square feet. A one-bedroom condo is also the slow product, 29 median days against 15 for two bedrooms, with 35% selling over asking against 52%.
- By district, the third bedroom ranges from +$88,000 in District 10 to +$579,000 in District 5 and about +$1.5M in District 7, and the ladder steepened this year: two-bedroom houses rose 7.7% year over year, three-bedrooms 16.0% and four-bedrooms 20.2%, so the bigger the home, the bigger the gain.

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.
