4 building permits issued at
this address, worth $178,000 of declared work and
$11,287 in fees paid to the city.
Gathering these permits into one address is One Public Budget's doing.
The city publishes one permit at a time and never says two are at the same place. We
match them on the house number and street — the county's spelling where it publishes
one, the permit's where it does not — so unit numbers and street-type spellings do not
split one address into several. Every figure below is the city's, exactly as printed;
only the grouping and the totals are ours.
Starting the 3D view…
OpenStreetMap records no building outline here, so what is drawn is the lot
itself, from the county's parcel map. That does not mean the lot is
empty — it means nobody has mapped a building on it.
Nothing in this view points at a part of the building. Arcadia's
permit listing says what work was permitted and at what address; it does not say
where on the property the work happened, so One Public Budget does not place it.
declared job value — the figure the applicant stated the work was worth, which is
what the city prints. Not an assessment, not a sale price, and not what the work
finally cost.

What this page does not tell you
Whether any of this work was finished, inspected, or is still going on. The city's
monthly listing records that a permit was issued and nothing after that. There is also
no record here of any application that was refused or is still waiting — Arcadia does
not publish those as data. And these are only the months One Public Budget has ingested;
work permitted before or after them is not on this page. Nor is this page a claim that
the city treats these permits as one project — it is One Public Budget observing that
they name the same address.
