Check any Boston parcel’s zoning in 60 seconds, free

Before you can price a deal, file for relief or sketch a scheme, you need three things: what the zoning allows, what’s on the lot today, and how the ZBA has ruled nearby. In Boston that usually means three separate city websites. Stratum puts them on one map.

Type an address and Stratum finds the parcel. The Zoning tab shows the district and subdistrict, and lines up what the code allows against what exists: lot size, frontage, front, side and rear setbacks, height, stories and FAR. Existing values are approximate, measured from City of Boston map data. The Precedents tab lists nearby ZBA decisions with the date, the outcome, the relief requested and a link to each case. Those decisions also show on the map as green (approved) and red (denied) dots around your site.

You can try it on up to three properties with no account. Sign up free to save results and projects. Try it now
