Verification ## What we verified Fact Status Source 2 legal units corroborated the 2025 secured roll carries 2.0 units on APN 6639034 under property class F, Flats and Duplex; the live listing as we verified it on 2026-08-23 carries a units chip of 2 and a Duplex subtype; two full baths bound the count; and RH-2 zoning permits exactly two. units-concordance reads the record corroborated with no conflicts 3,100 sqft, 4 beds, 2 baths, built 1908 corroborated the 2026-08-25 feed row and the live listing (verified 2026-08-23) agree on all four, and the 2025 secured roll independently carries 3,100 square feet of property area and the 1908 build year. The city's historic-status record for this APN carries 1908 as well Ask $1,295,000, listed 2024-09-16, no price change since verified 2026-08-25 feed; the live listing's price agrees to the dollar and the listing's price history holds a single event, one listing and no cut, with no prior sale recorded Assessed $335,501 for the 2025 roll year: land $106,699, improvements $228,802 records DataSF secured roll, block 6639 lot 034, closed roll year 2025; the listing's own tax-assessment field carries the same $335,501 No reassessment step in nineteen consecutive roll years, 2007 through 2025 records DataSF secured rolls 2007-2025 read year by year for this APN: the total climbs from $250,430 to $335,501 on the Prop 13 inflation factor alone, dipping once in 2010 with that year's negative factor. The land share holds at 31.8% throughout. No change of ownership and no reassessable construction inside that window Seller's 2025 property tax $4,916 on the $335,501 roll, an effective 1.465% records tax history on the listing, three years on file: $4,624 on $322,474 in 2023, $4,749 on $328,923 in 2024, $4,916 on $335,501 in 2025. The modeled 1.183% ad valorem on that roll would be $3,969, leaving about $947 a year of direct charges the modeled line does not carry Show the other 12 checks Fact Status Source No measured FY 2025-26 secured tax bill unverified no SF Treasurer pull for account 6639-034 this pass. our archive of FY 2025-26 secured bills holds four and this parcel is not among them, so the tax line stays the modeled 1.183% consolidated rate and the CFD question is unread in either direction The property is tenant occupied stated the listing prose, which says the property is currently tenant occupied without naming a unit, a tenancy count or a rent. The page's total-actual-rent field is empty, which is an absence and never a claim of zero Two tenancies filed at this building in the Rent Board registry's 2026 cycle: a three-bedroom begun 2019 in the $7,000-and-up band, a one-bedroom begun 2022 in the $2,501-$2,750 band, both occupied by non-owners records registry tenancy biography, narrowed on block 6639 from seven clusters by unit count of 2 and a bedroom sum of 4 to a single building record. That record carries an 1890 build year against this parcel's 1908, so read the match as probable and short of settled; the registry files the tenancy and never the person One building permit on the parcel in the city's census, ever: a 2003 over-the-counter sidewalk repair at $0 declared cost verified DBI building-permit census (DataSF i98e-djp9, pulled 2026-08-24), re-counted here across all 1,294,263 rows for block 6639 lot 034. Permit M24554, filed and issued the same morning of 2003-08-12, description sidewalk repair Two DBI complaints on the parcel, both closed, both about a dwelling in the garage verified city-records overlay, block 6639 lot 034: complaint 200911141 filed 2009-06-22 alleging a possible illegal garage unit with garage and yard full of junk posing a fire hazard, abated 2009-07-07; complaint 201475871 filed 2014-05-30 alleging an unapproved unit at garage level with a gas cooktop and no ventilation, closed 2014-08-04. Both read Not Active Zoning RH-2 (two-family), 40-foot height limit, inside the Central Neighborhoods Large Residence special use district verified DataSF zoning, height-bulk and special-use joins on the parcel centroid: RH-2 under Planning Code 209.1, height district 40//40-R-4. Zoning on the listing's own facts panel reads RH2. The Large Residence district's provisions were not read for this record Not on the mandatory soft-story list; no notices of special restriction; no planning applications; no liquefaction, landslide, hazardous-soils or air-pollutant row; no Rent Board appeal or petition within thirty meters verified city-records overlay: each of those layers records looked=true for this parcel and returned zero rows, the hazard joins on the parcel centroid and the Rent Board joins by proximity Historic status CEQA category B: no evaluation, and 45 years or older records city historic-resource record for APN 6639034, data as of 2026-05-12. The code records that nobody has looked, and it is no kind of clearance No buyout disclosure has ever been filed for this address; nineteen sit within two hundred meters of it verified Buyout dataset held by the SF Rent Board (wmam-7g8d, 8,498 geocoded rows), joined here by parcel centroid. Nothing at 375 Day Street. Within two hundred meters, nineteen filings since 2015, ten of them carrying a completed agreement at $0, $14,828, $20,000 three times, $50,000, $55,000, $60,000, $107,920 and $142,517. The nearest is 381 Day Street, sixteen meters away, $50,000 for two tenants in 2019 15 listing photos analyzed; every frame is an exterior, a map or a street scene verified photo-capex stage v4 (2026-08-31), citation-checked by eye against the stored frames on 2026-08-30: frames 1, 3, 8 and 14 are the facade, a second facade angle, an aerial map graphic and a streetcar street view. The flag moved from five cited frames to frame 1 Land share of the roll is 31.8%, against the 40% regional default the model carried diverges 2025 secured roll ($106,699 land on $335,501) against the modeled 40% land share, which an earlier modeling pass carried because the assessor was recorded as not accessible that run. The split feeds depreciation only, and depreciation is inert under the pre-tax convention, so no modeled number moves The ask is $418 a square foot, under the 25th percentile of comparable local sales records $1,295,000 over 3,100 square feet. The 36-month sold sweep for 2-4 unit buildings in this ZIP holds 57 sales in the 2,015-4,185 square foot band at $466, $612 and $869 a foot across the quartiles 15 facts checked against a named source. 3 we could not settle. 11 open questions, written out in the underwrite. Assessor ## What the roll says Assessed value $335,501 Rate used 1.183% Tax bill at this ask $15,321/yr A bill on the roll belongs to the seller. A sale resets the assessment, so the figure above is what a buyer at this ask would owe. Community facilities district: unchecked: with no secured bill in hand, neither a Mello-Roos or CFD line nor the parcel's ordinary direct charges have been read either way. The roughly $947 a year implied by the listing's own totals is unnamed and unallocated. Standing ## Where this sat Underwritten in the San Francisco run of October 6, 2026. Next ## This is one row of the San Francisco board. The run of October 6, 2026 put every two-to-four-unit listing in San Francisco through the same comparison.
