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

Here is how I would think about this. A San Francisco home search almost always opens with a number typed into a filter box. Two if it is a couple. Three if there are kids. Four if the plan is to stay put for a long while. That number sets a budget before anyone has priced it out loud, so this issue prices it. What does each rung of the ladder actually cost? Then there is a second question, and it is the one that decides whether you overpay. Keep the floor area the same, and is another bedroom worth paying for?

Start with the short version, drawn from 4,804 closed sales over the last 12 months. A third bedroom in a house runs about $469,000, and a fourth runs about $831,000. The part worth pausing on is where that money goes. Very little of it pays for a bedroom. Most of it pays for the square feet the bedroom happens to sit in.

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

Take the 12 months ending September 1, 2026. The median two-bedroom single-family house sold at $1,400,000, on 485 sales. Three bedrooms landed at $1,869,000, on 894. Four bedrooms at $2,700,000, on 607. Above that the group gets smaller and much less uniform, running from in-law warrens in the Excelsior to mansions in Pacific Heights. Five or more bedrooms came in around a median $3,305,000 on 264 sales.

Look at those as steps rather than as prices. Moving from two bedrooms to three costs another $469,000, a climb of 33.5%. The step from three to four is $831,000, or 44.5%, close to double the one below it in dollar terms. So the rungs are not evenly spaced. They spread out the higher you go.

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

Condos and townhouses have their own ladder, and its bottom rung sits much lower. One bedroom: $730,000 on 823 sales. Two: $1,350,000 on 1,089. Three: $1,900,000 on 507. Four: $2,525,000, though on a thin 74 sales, so I would read that top rung as directional only. The big jump in condo country is the second bedroom, $620,000 and an 85% climb, largely because the one-bedroom rung starts so low. After that the steps settle down, $550,000 for the third and about $625,000 for the fourth.

Downtown shows the same pattern in sharper form. The second bedroom there is a $647,500 step. Median one-bedroom $702,500, median two-bedroom $1,350,000, on 338 and 329 sales, across SoMa, South Beach, Mission Bay, Yerba Buena and Van Ness/Civic Center.

Are you paying for the bedroom or for the floor area?

Here is the fact that reorganizes everything above it. Per square foot, the three rungs cost the same. $1,132 per square foot at two bedrooms. $1,125 at three. $1,138 at four. What separates them is not rooms. It is floor area, with median sizes of 1,214, 1,710 and 2,412 square feet. My read: a buyer is paying roughly $1,130 a foot for a bigger house, and the bedroom count is mostly the shorthand a listing uses to tell you how big it is.

So the team took size off the table and looked band by band. Same square footage, one extra bedroom, what did it sell for?

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.

If you have ever put up a wall to create a bedroom, this part may be uncomfortable. Hold house size steady above 1,400 square feet and the fourth bedroom stops paying. At matched square footage, four-bedroom houses sold for less than three-bedroom houses: $1,610,000 against $1,759,000 in the 1,400 to 1,800 band, $2,050,000 against $2,160,000 from 1,800 to 2,200, and $2,850,000 against $3,000,000 from 2,200 to 2,800. Those bands carry 59, 137 and 197 four-bedroom sales, so this is not one odd month. Lower down, between 1,000 and 1,400 square feet, the third bedroom was a wash, $1,370,000 against $1,369,000. Interpretation rather than fact: four bedrooms squeezed into 1,600 square feet is four small rooms, and the market appears to pay for rooms people can live in.

Condos behave differently, and only at one rung. +$142,500 is what a second bedroom added at 700 to 1,000 square feet, and +$370,000 at 1,000 to 1,300, on 372 and 178 sales in the smaller band and 82 and 437 in the larger one. That premium holds even with size fixed. A 1,100-square-foot one-bedroom and a 1,100-square-foot two-bedroom are simply not the same product, and the pool of buyers for the second one is far deeper. The third bedroom is a different story. It added nothing between 1,000 and 1,300 square feet, $42,500 between 1,300 and 1,700, and only began earning its keep above 1,700, at roughly $152,500.

Which districts charge the least for a third bedroom, and which charge the most?

Geography changes this answer a great deal. Cheapest is $88,000 in District 10. Bayview and the Excelsior have fairly uniform housing stock, and the extra room there is often a basement conversion. Dearest among the rated districts is $579,000 in District 5, which covers Noe, the Castro and the Haight. District 7 sits near $1.5 million, though so few two-bedroom houses trade there that the rung goes unrated. Out west the ladder stays flat. In the Sunset, District 2, a third bedroom ran $251,000 and a fourth $343,000, on 104, 187 and 96 sales. Cross into the Richmond, District 1, and those same rungs cost more than twice as much. Sample sizes and a reliability label sit on every cell of the full table under By the numbers.

Which bedroom count sells fastest?

Houses hardly notice the difference. Whether a house had two, three or four bedrooms, the median time to sell was 12 days, and 82% to 87% of each group closed above asking. Only the five-plus group takes longer, at 14 days, with 63.6% over asking. My read is that the very top of the market tends to negotiate instead of bid.

Condos are where the clock splits, and it splits at the second bedroom. One-bedrooms took a median 29 days, with 35.1% selling over asking. Two-bedrooms took 15 days, with 52.0% over. Three-bedrooms, 13 days and 64.7%. That makes the one-bedroom condo the slowest and softest product in this issue. Read the other way, that softness is where the second bedroom premium comes from.

The rungs spread further apart this year

The gain scaled with the size of the house. Four-bedrooms rose 20.2% year over year, from $2,247,000 to $2,700,000. Three-bedrooms rose 16.0%, from about $1,611,000 to $1,869,000. Two-bedrooms rose 7.7%, from $1,300,000 to $1,400,000. That is the house-market heat this series has followed since Issue #13, and it now reads as space opening between the rungs. Condos moved far less, with one-bedrooms up 3.2% to $730,000 and two-bedrooms up 8.1% to $1,350,000.

Using this in practice

If you are buying, here is what I would suggest. Start with square footage and neighborhood, then look hard at the floor plan, and let the bedroom count be a filter rather than the thing you are paying for. A well-laid-out 1,700-square-foot three-bedroom tends to beat a chopped-up 1,700-square-foot four-bedroom on price, on light and on resale, and the closed sales already reflect that. Condos flip the logic once. If a two-bedroom is within reach, the second bedroom appears to hold its value and it sells in about half the time, so it may be worth stretching a little. If it is not within reach, I would rather you not force it.

If you are selling a house, I would not build a wall to manufacture a bedroom. A converted dining room turns a three-bedroom into a four-bedroom that still sells like a three-bedroom of that size, only now without a dining room. The same budget spent on the rooms you already have tends to do more. If you are selling a one-bedroom condo, plan for a 29-day market and for a buyer pool that mostly does not bid above asking. I would lead with the square footage and the outdoor space, since those are what your buyers weigh you against when they look at two-bedrooms.

Whatever the situation, I would pull the numbers for your own bedroom count on your own block before fixing a budget or a list price. Citywide medians give you the shape of the market. Your block is what you actually buy and sell in.

Frequently asked questions

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

Across the 12 months ending September 1, 2026, the citywide median was $1,869,000, drawn from 894 sales at a median size of 1,710 square feet. District by district the range is wide. District 10, covering Bayview and the Excelsior, came in at $1,123,000. District 7, the Marina and Pacific Heights, came in at $4,215,000.

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

The citywide gap is about $831,000, which is $2,700,000 set against $1,869,000, a step of 44%. Most of that is floor area rather than the room itself, since the median four-bedroom measures 2,412 square feet against 1,710 for a three-bedroom. Hold size constant and the picture reverses. In every band from 1,400 square feet up, four-bedroom houses sold for less than three-bedroom houses.

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

Over the 12 months ending September 1, 2026, the median came to $1,350,000, on 1,089 sales and a median size of 1,232 square feet. For context on either side, one-bedrooms had a median of $730,000 and three-bedrooms $1,900,000.

Does adding a bedroom increase home value in San Francisco?

Only when it brings floor area or a better layout with it. In houses the price per square foot barely moves across two, three and four bedrooms, around $1,130, and a fourth bedroom carved out of an unchanged footprint actually sold $110,000 to $150,000 below a three-bedroom of the same size. Condos are the one exception, and only at the second bedroom, which added $142,500 to $370,000 at matched size. A third added very little until roughly 1,700 square feet.

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

Two bedrooms, clearly. Take the last 12 months: 35% of one-bedroom condos cleared asking, and the median one needed 29 days to sell. For two-bedrooms it was 52% over asking at a median 15 days. Houses beat both, selling in a median 12 days at two, three or four bedrooms.

AI Corridor Scoreboard

The condos near the new AI offices are the softest corner of the market right now. One reading on them per issue, so you can follow the turn while it happens rather than after.

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.

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

Exact medians for the last 12 months. Houses: $1,400,000 at two bedrooms, $1,869,000 at three, $2,700,000 at four, $3,305,000 at five or more. Condos: $730,000 at one, $1,350,000 at two, $1,900,000 at three. Stated as steps, a third bedroom in a house adds roughly $469,000 and a fourth roughly $831,000, close to double.
Bedrooms are not what the money buys. Price per square foot holds nearly flat across two, three and four bedroom houses, $1,132, $1,125 and $1,138, or about $1,130 either way. What changes is size, at a median 1,214, 1,710 and 2,412 square feet. That is the ladder being climbed.
Above 1,400 square feet, a three-bedroom outsold a four-bedroom of the same size in every band. In the 1,400 to 1,800 range that was $1.76M for three bedrooms against $1.61M for four, and from 2,200 to 2,800, $3.00M against $2.85M. So at fixed size the fourth bedroom reads as a discount, not a premium.
One exception runs the other way. A second bedroom in a condo pays for itself even at matched size, worth $142,500 more between 700 and 1,000 square feet and $370,000 more between 1,000 and 1,300. Past that, a third adds nothing until roughly 1,700 square feet. The same split shows up in speed: one-bedrooms took a median 29 days against 15 for two-bedrooms, and 35% sold over asking against 52%.
District spread on the third bedroom runs from $88,000 in District 10 up to $579,000 in District 5 and about $1.5M in District 7. The rungs also spread apart over the year, with two-bedroom houses up 7.7%, three-bedrooms up 16.0% and four-bedrooms up 20.2%. The larger the home, the larger the gain.

Every San Francisco neighborhood has its own median price, sale-to-list and market time, with a bedroom filter, inside the market explorer. I would start there, with your bedroom count and your neighborhood, before landing on a budget, whether that is Russian Hill, the Excelsior or Crocker Amazon.

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.
