Residential units authorized per 1,000 existing housing units
How much residential construction is underway in this town, relative to the housing that already exists?
12 of 18 towns publish a figure today · measured 2026-09-02 · every figure carries its source, its date and the test that decided what counted.
What the two ends mean
10 = the most construction underway. 1 = the most settled housing stock. Neither end is better than the other.
What this number is not a judgment about: it counts permits already issued against housing already standing. It says nothing about what the homes here are worth, what they will be worth, what the existing housing is like, or who lives in it.
A 10 means the town has at least a published amount of something — a threshold set in advance and the same for every town. It does not mean best. Several of these run opposite to each other: the town with the most restaurants per resident will almost never be the town with the biggest lots. Read the number, not the band. How this is measured, and what it does not measure.

Why a town shows no figureThe inclusion test requires all twelve months in each of the three years, so no three-year average is published here and none is estimated. The figure the survey publishes for a short-reporting year is part imputed; using it would be a measurement taken by a method other than the one the methodology specifies. The cell fills the next annual pass in which all three years report twelve months.
Every figure above is in the same unit: units authorized per 1,000 existing housing units. Nothing in a row describes any other town.
The published ruler
Nine edges, in units authorized per 1,000 existing housing units, set in advance and identical for every town. The band is arithmetic: one plus the number of edges the measurement reaches or clears. A measurement sitting exactly on an edge belongs to the higher band. Anyone can recompute our band from the figure on this page and the edges below.
5 · 10 · 15 · 20 · 30 · 40 · 50 · 65 · 80
Edge-table version v1.1 · basis B+O (P = physical or structural anchor, B = external benchmark, O = observed regional range) · re-measured on the A-tier cadence · pulled by the index-automation role, which owns the pull and never the result.
Part of this ruler was set from the range observed across Middle Tennessee rather than from a physical anchor or a published external benchmark, and that observation base was partial when the edges were set. Under the methodology's edge-governance rule an edge can change only as a published version bump that re-bands every town at once — never a per-town edit, never within twelve months of the last change in this category, and never while a town's measurement here is pending. The methodology separately schedules a single, announced re-set of observed-range edges after the first complete eighteen-town pass, and names the categories that carry it; this one is not among them today. If that ever changes, it is announced here before any band moves.
What was counted
Residential units authorized by building permit inside the municipality, summed across the four unit-size classes the Census Building Permits Survey publishes (1-unit, 2-unit, 3–4-unit, 5-or-more-unit) in its place-level annual file, for 2023, 2024 and 2025; averaged over the three years; divided by the place's housing units from the American Community Survey 5-year table B25001, latest released vintage; multiplied by 1,000. A place-year counts only where the survey's months-reported field is 12. Where any of the three years reports fewer than twelve months, the cell is not published and no figure is estimated in its place.

Where this measure could go wrong, and what we did about it
Growth language is where this category leaks. Everything published here is past tense: permits already issued, housing already built. No forward-looking statement of any kind attaches to this number, no expectation about prices, and the share of housing built 2010 or later is never paired with a description of the housing that already stands or of anyone living in it. The new-versus-old housing contrast has carried coded meaning for seventy years; the compliance gate blocks the euphemisms by name, and this category measures new supply and contrasts it with nothing. No builder is named, compared or ranked here.
There is a published list of what this index refuses to measure, and why, with somewhere useful to go instead for each one. Read what we do not measure, and why.
For Will, Mindy and John
Saying this out loud
One rule carries this whole card: say the number, not the placing. Everything else follows from it.
Not: a sentence that names a winner, in any wording — including “has the most.”
“Brentwood permitted about eight new units for every thousand it already has, averaged over the last three years. Gallatin’s figure is about sixty-nine. Which of those is the number you care about?”
Two figures with their unit, and a question. No superlative, no ordering, no verdict — and it ends with the client talking.
- ·Name the tradeoff in the same breath. A town in the middle of construction and a town whose housing is mostly already built are two different facts, not a better and a worse.
- ·Never add bands across categories, out loud, for anyone, including as a joke. The units are not commensurable; the sum means nothing and sounds like a verdict.
- ·Never repeat an ordering off a category page as a recommendation. The page lets a reader sort one column of one unit; that does not license us to read the result back to them.
- ·If the question is “which one is the best?” — answer “that depends on which of these you want most of, and here is how they trade off.” Never answer the question as asked.
- ·If the question is which town has the most of something — the question our own category pages invite — give two or three towns’ numbers, in order of nothing, and let the client decide which matters to them.
- ·Never volunteer, and never confirm, anything this index does not measure. Point to the methodology page, which names every exclusion and where to go instead.

Working out where you fit
These eighteen measures trade off against each other by design. If you would rather answer eight questions than read eighteen columns, the quiz walks the same tradeoffs and shows its reasoning.
