Verification

What we verified

Fact	Status	Source
4 units	corroborated	Four units appears in the seller’s own words: "Fantastic four unit property in ideal Peninsula location. Four large townhouse style units with two bedrooms and one and a half baths each." The public listing's structured subtype reads Quadruplex, Residential Income and its unit field reads 4, though those two count as one witness, because the field is parsed from the subtype string. Our units concordance returns corroborated with no conflict.
the arithmetic agrees with four two-bedroom flats	corroborated	Eight bedrooms across four units is two apiece, and one and a half baths per unit is six, which matches our listing feed. 4,767 square feet divides into four flats of about 1,192 square feet, which is townhouse scale. Four garage spaces is one per unit. Every figure the seller states is consistent with the mix the seller describes.
the building is residential, with no commercial component	corroborated	One parcel number, 011-262-300, on one county tax account, with no lettered sibling accounts in the portal address search. Third-party listing syndication reports the parcel zoned R30000. Last week this region published a row that turned out to be a mixed-use retail building, so we checked this one deliberately.
baths: our feed and the listing prose say six, the public listing's facts panel says eight	divergent	The seller's own sentence gives one and a half baths in each of four units, which comes to six. Our listing feed says six. The public listing's structured facts panel says eight, and did so in two independent verified readings a month apart, so it's a stable read and no parse slip. We carry six, because the prose is the seller's own statement of the mix and the arithmetic follows it. Bathrooms feed no number on this page.
ask $1,795,000	corroborated	Our 2026-09-24 listing feed and the same day's verified reading of the live listing agree to the dollar. The ask was $1,868,000 when we first published this building on 2026-09-10.
the parcel's tax bill	measured	The San Mateo County bill itself, read from the county's own tax portal on 2026-09-10 and held in our tax-bill archive. It closes to the penny: ad valorem $18,366.36 at 1.0718% on a net assessment of $1,713,600, plus $3,090.78 of fixed direct charges. Tax rate area 013032. Both installments cleared, 12/01/2025 and 04/08/2026. This is our first San Mateo County bill.
the listing is live	corroborated	Read as for sale on 2026-09-24 at $1,795,000, 56 days on market by the public listing's count. Beds, square footage and MLS number match our earlier reading exactly.
about $50,000 of recent work, and SB 721 compliance	single-source	Only the seller says so, and the listing gives no dates, no costs beyond the round figure, and no permit numbers. SB 721 is California's balcony and stairway inspection law, so a compliance claim implies somebody inspected the building, and that report is missing from the evidence.
