Behind every zoning code is a story about who gets to live where, & why. That’s why we're proud to launch our Media Resources page—a one-stop hub for journalists looking to turn complex zoning info into digestible, data-driven narratives.

31.07.2025 16:37 — 👍 0 🔁 0 💬 0 📌 0This change required our full text-analysis team to manually extract “minimum-minimum” lot sizes, & “maximum-minimum” lot sizes across tens of thousands of individual zoning districts.
31.07.2025 16:37 — 👍 0 🔁 0 💬 1 📌 0Capturing all the possible variations of lot sizes, standardizing their unit conversions, & packaging them into legible graphics for every locality in the country is no small feat!
31.07.2025 16:37 — 👍 0 🔁 0 💬 1 📌 0If the range spans multiple categories, or involves complicated formulas or contextual rules that prevent calculation of a range, then it falls into the “Varies” category. In the map itself, you can locate these districts with the “Varies” checkbox under Advanced Filters.
See zoningatlas.org/atlas
Moreover, the donut now captures districts that vary *within categories.* If the range falls within one of our set categories, it is represented in that category. A district requiring 10,000 SF for elderly housing & 15,000 SF for affordable housing now falls into the “10,000 SF-19,999 SF” category.
31.07.2025 16:37 — 👍 0 🔁 0 💬 1 📌 0In all, the first donut omitted nearly 10,000 acres (8% of single-family land) with varied mandates. The second donut includes them—and, by extension, illuminates the Cape’s regulatory complexity.
31.07.2025 16:37 — 👍 0 🔁 0 💬 1 📌 0These graphics show a second big data visualization change for MLS rules.
In the first donut, there is no “Varies” category. That donut omits districts requiring different MLS rules depending on a lot’s location (eg. corner or interior), the type of housing (eg. affordable or elderly), or context.
The new SF method results in a donut showing that 77% (62%+15%) of single-family land requires a MLS over 40,000 SF. This is because so many Cape Cod towns set their MLS to 40,000 SF. We believe the latter figure better communicates how these towns zone.
31.07.2025 16:37 — 👍 0 🔁 0 💬 1 📌 0Compare before-and-after Zoning Snapshot “donuts” showing single-family MLS mandates in Barnstable County, MA (Cape Cod). The prior method resulted in a donut showing that 48% (36%+12%) of single-family land required a MLS over an acre.
31.07.2025 16:37 — 👍 0 🔁 0 💬 1 📌 0But we noticed something. Codes using SF tend to use round numbers, like 10,000, 20,000, & 40,000 SF, functioning as the “builder’s” quarter, half, & whole acre. Makes sense: 40,000 SF is 92% of an acre. But our map & Zoning Snapshots omitted 40,000-SF lots from one-acre calculations.
31.07.2025 16:37 — 👍 0 🔁 0 💬 1 📌 0First, here’s why we switched to SF:
Some zoning codes use SF to define MLS rules, some use acres, & some use both. Previously, we converted all units to *acres*. One acre—rooted in the English Imperial system of measure & defining the land a yoke of oxen can plow in a day 🐮—is equal to 43,560 SF.
