How to read a San Diego report

What the city publishes, what the region publishes, and why this city's counts carry a date the others do not.

Two publishers, two dialects

The parcel half of a San Diego report is read live from SANDAG, the regional agency that publishes the county's spatial data: the address register, the parcel with its assessed values and its last recorded document, the zoning, the community plan, the hazard layers, the parks and the transit stops. Ask for an address and those are current at that instant.

The block half is different. The city publishes police incidents, 311 requests and development permits as files with no query interface at all, so this report downloads them, holds a copy and counts against it. Every one of those sections prints the day its copy was taken. Its own guide is next door.

One number the register gives you free

San Diego's address register carries the assessor's parcel number in a column beside the address. Los Angeles and Oakland both need a point-in-polygon lookup to cross from a city record to a county one, and each has its own way of failing. Here there is nothing to bridge.

What a comparison claims

An area count carries a ratio against the city's own average: this many records fell inside your radius, against the number you would expect if the whole city's records were spread evenly. It is arithmetic about a dataset, not a judgment about a place. Somewhere busy reads high on almost everything, because more of everything happens there.

Because the whole city is held in memory for these streams, the denominator is exact for the same window as the numerator rather than a cached approximation of it. That is the one thing files do better than a portal.

Counts run 5 September 2026.

Why this city's numbers say when they were takenSan Diego publishes its whole transactional record as files with no way to query them. So this report holds a copy, and tells you how old it is.What a San Diego assessment actually isAnchored to the last sale, capped at about two per cent a year, and published as one roll rather than a run of years. Why a seller's bill says nothing about a buyer's.What San Diego files every dayFive lists from the city's permit file, keyed on the day an approval was issued rather than the day it was asked for.
