Terms of use

This is a calculation aid. It is not a zoning determination, a permit review, a survey, or legal, architectural or engineering advice, and it does not replace review by the municipal zoning officer or a licensed professional.
The numbers may be out of date, incomplete or wrong. Towns amend their zoning, and some towns here were entered from older schedules, as each town's page says. No one guarantees that any requirement shown is current or correct.
You are responsible for checking. Before you design, apply for a permit, buy property or build, confirm every requirement against the municipality's current code and with its zoning officer.
Not everything is checked. Each town's page lists what it leaves out. Other rules, such as easements, deed restrictions, environmental limits and historic review, can also affect a project.
No warranty. The site and its tables are provided as is, without warranties of any kind, express or implied.
Limit of liability. To the fullest extent the law allows, the operator of this site is not liable for any loss, cost, delay or damage that comes from using or relying on the site or its tables. If liability cannot be excluded, it is limited to the amount you paid for access.
No affiliation. This site is not affiliated with, or endorsed by, any municipality.
Agreement. By using this site, or by buying or unlocking the full table, you agree to these terms.

Privacy

What you type stays in your browser. The numbers and addresses you enter are saved only in this browser, so they are there when you come back. They are not sent to this site.
The address lookup is the exception. If you press "Find my lot and zone", the address you typed goes to the State of New Jersey's public parcel service, and the lot's map position to the regional zoning map run by the North Jersey Transportation Planning Authority.
Your license key. When you unlock the table, the key is checked with Gumroad and kept in this browser. "Remove the key from this browser" deletes it. Payments are handled by Gumroad; this site never sees your card.
Visits. The host keeps standard server logs, and Vercel Web Analytics counts page views (which pages, the referring site, country and device type). It also counts steps on this site: which town was checked, how far the check got, and whether the buy or "ask us to add" button was pressed. The address you type is never included. It uses no cookies and stores no personal information. This site sets no advertising or tracking cookies.
