Downtown SF, CA Real Estate & Homes for Sale
On the MLS, Downtown San Francisco is the grid of apartment and condo buildings between Nob Hill and Union Square, roughly Polk to Stockton Street. Much of it was rebuilt after 1906 as apartment buildings and apartment hotels in a National Register historic district, and owners have BART, Muni Metro and cable cars nearby.

On the SFAR MLS, “Downtown” (subdistrict 8A) is not the office core: it is the grid of apartment and condo buildings between Nob Hill and Union Square, roughly Polk Street to Stockton and Sacramento or California Street to O’Farrell, that many people call Lower Nob Hill. The Union Square shopping blocks carry their own Assessor code, 8I, and the high-rise office district is coded to the Financial District. If you are searching for a downtown home, those three codes describe very different buildings.
The 8A blocks sit below Nob Hill, north of the Tenderloin, east of Van Ness/Civic Center and west of the Financial District. The SF District 8 guide places them alongside the other eight subdistricts.

Which downtown the MLS means
The Assessor’s roll uses the same letter codes as the MLS. Mapped from parcel points, 8A covers about Polk Street east to Stockton and about Sacramento Street south to O’Farrell; Bush, Sutter, Post and Geary are its main cross streets. Parcels just north of it are mostly Nob Hill (8C), and the blocks below O’Farrell are mostly Tenderloin (8J).
Union Square, the Assessor’s 8I, takes the blocks from about Taylor Street east to Kearny and Montgomery, between Market and Bush. Ask how a listing was coded if a Union Square address matters to you; our District 8 overview notes that 8I does not appear as a separate neighborhood on the SFAR map it used.
Built after 1906: apartment buildings and apartment hotels
Much of 8A is apartment buildings and apartment hotels from the decades after the 1906 earthquake and fire. The Lower Nob Hill Apartment Hotel Historic District, listed on the National Register on July 31, 1991, covers much of that rebuild: Planning’s record gives a period of 1906 to 1940 and counts 296 contributors among 337 resources.
If a building contributes to the National Register district, ask Planning how the listing affects a specific project before you plan exterior work.
For the older stock, the inspection list starts with structure and systems: elevators, boilers and risers, windows, fire escapes and any seismic strengthening. Our guide to older San Francisco buildings covers the wood-frame side of that history.
Ownership forms on the 8A roll
Compare the particular property’s lot dimensions, permitted living area, construction history and ownership form using current records. Assessment classifications do not certify legal use or current listing availability.
The condo guide covers association documents and financing, and the BMR homes guide explains the resale-restricted units.
Zoning, special use districts and Union Square’s conservation district
Planning’s special use district layer shows the North of Market Residential SUD (subareas 1 and 2) reaching into parts of these blocks, the Nob Hill SUD along the northern edge and a site-specific 901 Bush Street SUD. Planning Code section 249.5 says the North of Market district aims to protect housing near downtown and to limit tourist hotels; hotels and motels are not permitted uses there, and demolishing a building with dwelling units needs conditional use approval.
The Kearny-Market-Mason-Sutter Conservation District, adopted under Article 11 in 1985, covers 323 properties, 252 of them contributors, and shapes how storefronts and facades there can change. The General Plan’s Downtown Area Plan also calls for expanding housing in and next to downtown while preserving residential hotels.
Seismic, balcony and residential hotel rules for older buildings
Three sets of rules come up often in 8A sales:
- Soft-story retrofit. The city’s mandatory program targets older wood-frame apartment buildings: five or more units, at least three stories (two if over a basement or underfloor space), and a construction permit applied for before January 1, 1978. Buildings that are not wood-frame fall outside it, so confirm the construction type from the permit record. Our seismic retrofit guide explains the work.
- Balcony and stair inspections. Apartment buildings with three or more units fall under Health and Safety Code section 17973 (SB 721): at least 15 percent of each type of wood-supported balcony, deck, stair or walkway inspected by January 1, 2026 and every six years after. Condo buildings follow Civil Code section 5551 instead. See our SB 721 guide.
- Residential hotels. Under Chapter 41 of the Administrative Code, adopted in 1981, an owner who plans to sell a residential hotel must complete a Residential Hotel Status Report that DBI’s Housing Inspection Services verifies, and the buyer must receive it before the sale.
On the ground itself, point checks against the state liquefaction map at Jones and Sutter and at Powell and Geary, by Union Square, were both outside the mapped zone. Check the parcel on our hazard maps guide before relying on that.
Getting around from Lower Nob Hill and Union Square
Powell St. station, under Market Street, serves BART and Muni Metro, and the Central Subway’s Union Square/Market Street station connects to it; SFMTA says the T Third began full service through the subway on January 7, 2023. Both Powell Street cable car lines start at Powell and Market and climb through the eastern 8A blocks, and the California line runs along the northern edge.
The 2 Sutter runs between Steuart and Market and California and Presidio, and the 38 Geary between the Salesforce Transit Center and the outer Richmond. Muni lines here follow published route lists; check SFMTA for current service.
Selling a home in Downtown
Buyers compare buildings before units: age and construction type, elevator and boiler condition, the reserve study and any special assessments, and whether a co-op board or a BMR restriction applies. A unit in a 1910s building with a recent retrofit and a well-funded reserve can compete with a newer one, but only if the records are ready.
- Condos: the Civil Code section 4525 package (budget documents, assessment statement, minutes on request and the latest balcony inspection report), plus the reserve study.
- Co-ops: the board’s application requirements, the building’s financial statements and the transfer rules.
- Apartment buildings: the rent roll, lease copies, Rent Board history, soft-story status and the SB 721 report.
- Residential hotels: the verified Residential Hotel Status Report under Chapter 41.
The city’s 3R report, water and energy rules and transfer tax are on our San Francisco seller requirements page; investors can also use the San Francisco multifamily page. The market report on this page shows current figures for the 8A code.
Questions people ask
Is “Downtown” on the MLS the same as the Financial District?
No. The MLS’s Downtown subdistrict, 8A, is the residential grid between Nob Hill and Union Square. The office core north of Market is subdistrict 8B, Financial District / Barbary Coast.
Is Lower Nob Hill part of Downtown on the MLS?
Mostly yes. The blocks below Nob Hill’s crest, from about Sacramento or California Street south to O’Farrell, are coded 8A by the Assessor, which uses the MLS letters.
Can you buy a home near Union Square?
Verify the particular property’s current records and dimensions; a neighborhood statistic is not a substitute for a parcel-specific answer.
What is the Lower Nob Hill Apartment Hotel Historic District?
A National Register district listed in 1991 that covers 337 resources from the post-1906 rebuild, 296 of them contributors. Ask Planning how listing affects a specific project.
Do I need a special report to sell a residential hotel?
Yes. Chapter 41 requires a Residential Hotel Status Report, verified by DBI’s Housing Inspection Services, before a residential hotel is sold or its title transferred.
Which BART station is closest?
Powell St., under Market Street at the foot of the Powell Street cable car lines. Montgomery St. is closer to the eastern edge of Union Square.

Costs to plan for when buying in Downtown
In 8A the main ownership forms are condominium units and co-op units, and each carries a different monthly cost structure. A condo owner pays a separate property tax bill plus HOA dues. In a co-op, the building usually holds one tax bill and often an underlying mortgage, and each owner’s share is paid through monthly carrying charges, so ask for the co-op’s budget, the underlying loan terms and the share of each item assigned to the unit. Lenders treat the two differently; read HOA documents in California and our condo guide.
The City’s transfer tax is charged at recording at $2.50 per $500 up to $250,000, $3.40 per $500 above that and below $1 million, and $3.75 per $500 from $1 million to under $5 million (SF.gov: Transfer tax). A Transfer Tax Affidavit, completed in English even when no tax is due, and a Preliminary Change of Ownership Report go with the deed; an exemption claimed for a transfer into or out of an entity or trust needs written proof filed at recording. See our San Francisco transfer tax guide.
The tax bill adds parcel taxes and any special assessments to the 1% base (Treasurer: parcel taxes and special assessments), and a reassessable ownership change may produce a supplemental bill or refund (SF.gov: supplemental assessments). Ask the HOA or co-op board whether the building has a seismic, elevator or façade project ahead, because those usually arrive as special assessments. See San Francisco property tax.
Rent, conversion and use rules for Downtown buildings
Much of the housing here is in pre-1979 apartment buildings, and the City’s rules turn on that date. Units in buildings built on or before June 13, 1979 often have both rent increase limits and just-cause eviction protection; condos rented to a tenant who moved in on or after January 1, 1996 generally have eviction protection only (SF.gov: rental laws). Buying a unit that comes with a tenant is covered in buying tenant-occupied property.
Larger apartment buildings require their own eligibility analysis; a unit count alone does not establish a conversion right.
Condominium conversion needs a building-specific eligibility review. San Francisco Public Works has a separate two-unit residential conversion process and publishes distinct Expedited Conversion Program updates. A historical lottery limit or ECP description is not a standing right to convert. Before assigning value to conversion, have Public Works confirm the actual pathway, ownership and occupancy history, tenant protections, eviction/buyout restrictions and any unauthorized-unit issue.
Wood-frame buildings of five or more units with a soft first story and an original permit applied for before 1978 fall under the Mandatory Soft Story Retrofit Program; those with ground-floor commercial space are in Tier IV (SF soft story program). Buildings that are not wood-frame are outside that program, so ask the seller what construction type the building is and whether any seismic evaluation or retrofit has been done. Our downtown condo building comparison lists the questions.
Luxury homes and estates in Downtown
High-end homes in 8A and the Union Square blocks are units, not houses: large condominiums and co-op apartments in the apartment buildings and apartment hotels rebuilt after 1906, and newer condo buildings. RM-4 and RC-4 zoning, the most common codes here, are high-density districts, so the premium is in the unit, the building and the services, not in land. Many buildings contribute to the Lower Nob Hill Apartment Hotel Historic District on the National Register; ask Planning how the listing affects any exterior work you plan, and check each building on the Property Information Map.
The due diligence that matters most: the building’s structural system and any seismic work; elevators, boilers and risers; the reserve study and the master insurance policy; the co-op’s financial statements and the board’s approval process for buyers; and the transfer tax tier, which rises to $11.25 per $500 at $5 million (SF.gov: Transfer tax). For earthquake and high-value coverage, see earthquake insurance and insuring a high-value home.
Some owners prefer to sell without public marketing. Ask Diamond Real Estate Group which permitted private-marketing options fit your property, goals and the applicable MLS rules. Availability of any particular listing is not guaranteed. Related reading: private sales · San Francisco luxury condos · Nob Hill. We do not promise that any particular property is available.
Mandatory soft-story coverage also depends on construction type, the original permit date, stories above a partly above-grade basement/underfloor area, the soft-story condition and any qualifying prior strengthening. Confirm the actual DBI screening and compliance record.
