Did the permit count fall, or did the record change?

Permit counts jump and drop for reasons that have nothing to do with demand: a city changes how it files or dates a record, or the wording and coverage shift. Here is a four-question check to run before you trust a big move in a permit chart.

Every step is explained below, with the official source for each fact.

Step by step

  1. Check how big the move is

    • Counts of a few dozen permits swing from quarter to quarter. A change of 50% or more is the point where it is worth asking why.
    • Our example: Austin commercial permits that mention EV chargers went from 32 in Q3 2025 to 16 in Q3 2026 (-50%). The monthly totals of all Austin commercial permits stayed in the same range (about 920 to 1,500 a month), so the drop is not simply fewer permits overall.
    • Fewer than 20 permits in the earlier quarter is too few to turn into a percentage. We show the counts and no percentage.
    Watch out: A partial month looks like a drop. Leave out the current, unfinished month.

  2. Ask whether the city changed how it records the permit

    • Cities change the date a record carries (applied, issued, finalled), the portal it lives in, and which permit types it counts. Any of these can move counts without any change on the street.
    • Open the city's own data page and read the field descriptions for the date you are counting. If the description changed, or the portal moved, treat the drop as a reporting change until shown otherwise.
    • Austin's open dataset, Issued Construction Permits, lists building, electrical, mechanical, plumbing and driveway/sidewalk permits by the date each was issued. Our Trends count uses its commercial permits only. The dataset page notes no change to its definition, and we have not found the cause of the EV-charger drop either.
    Watch out: Do not compare two cities head to head. They count and date permits differently.

  3. Check whether the wording or coverage changed

    • Counts like "EV charger permits" depend on the words in each record. If staff start describing the same job differently, or a permit type drops out of the dataset, the count falls and the work does not.
    • Pull ten records from each quarter and compare how the job is described. If the words differ, compare with care or skip the comparison.
    Watch out: A keyword count is a count of records that mention a word. It is not the number of chargers installed.

  4. If nothing above explains it, say what you know and no more

    • Only after the first three checks come up empty is a drop worth treating as a possible market shift, and even then it is one data point from one city.
    • When the reason is unknown, say "we don't know why yet." That is the honest answer, and it is what we publish.

Honest effort and what goes wrong

About fifteen minutes per chart once you know where the city documents its fields. Most of it is reading the city's data notes and ten sample records from each period.
