Already Known topic.Our definition of the class, 29 August 2026.

Snapshot taken 31 August 2026, based on 7 dated municipal records flagged as accessory dwelling unit in New York, spanning 6 municipalities. The topic moves; a later cut supersedes this page.

What this page is for one topic at state or national scope, told as a story: how it arrived, the shape of its movement, a dated snapshot of a moving record, and the door to a view of it that stays current. If it does not, write to us; that is what changes the next edition.

The story so far

The record starts in Madison County, 1 August 2023. Since then 6 New York towns have put the topic on a meeting record, the newest of them Elmira on 4 June 2026.

The last 90 days put 2 meetings on the record, more than double the 1 in the 90 days before.

It runs through the rooms where budgets and ordinances are made: Disease Surveillance Reports, Mayor&#39s Updates and Planning Board.

The shape of the movement

Dated meetings on the record at this scope, quarter by quarter, and the same 90-day count as a rolling line, whose right-hand point is that number. Counts of documents, never a reading of what they decided.

a rolling 90-day total, so the right-hand point is that same 90-day count. The busiest stretch was Dec 2025 to Feb 2026, with 2 meetings.

A snapshot of a moving record

Everything above is frozen at 31 August 2026; the topic is not. 36 more events on this topic carry no usable date and are counted, never dated. The counts follow where we read most: a town or a state absent here was not read at depth, and absence is not evidence the topic is absent there. A lighter-read state is not a ceiling; where you care about a region, pointing the system there is the first thing an account changes. How coverage is built, and its known limits: municipalalpha.com/methodology.

How we can tell you about it ongoing

We track this topic continuously; this page is one cut of it, taken 31 August 2026. An account turns the snapshot into a working view: every town and every document behind these counts, the thread on each matter as it develops, word of new meetings as they land on the record, your own states and topics side by side, and the data itself when you want it in a table. The towns above are the taste; what each is actually deciding, funding or stalling is the read an account carries.

Also at this scope: Accessory dwelling unit across the country. Counts and dates are computed from the documents on the record; the topic and its definition are ours. This page carries no subscriber content.
