DBI files the shared foundation permits under both lot 002 and lot 002A, so the raw query returns each twice; duplicates are collapsed here. The 1995–96 run is repeated underpinning and stem-wall foundation work along the north side of the building. One structure spanning two contiguous lots. Lot 002A is classed 'Single Struct on Multi Lot' and reports 0 building area — the building is carried on lot 002. Both parcels' assessor property_location reads 129 24th Avenue. Building measurements are from lot 002. No sale recorded on the current roll for either parcel.
One building, two lots and two numbers
The city treats 129 and 131 as a single structure on two parcels. The 131 lot is classed “Single Struct on Multi Lot” and reports zero building area — the building is carried entirely on the 129 lot — and both parcels' assessor records give the location as 129 24th Avenue. This site documents them as one building, which is why the page is titled with the range.
The guide's account
A published guide records 129 as Ansel Adams's childhood home, giving his birth on 20 February 1902, and 131 as a later property with a studio it says was destroyed in a sinkhole. The city data does not separate the two numbers into two buildings, so the guide's account of two houses is set out here rather than adopted.
