Use group
The Resolution's categories of permitted activities
Use groups are the Zoning Resolution's classification of activities — dwellings, shops, offices, factories, and everything between — into numbered categories that districts then permit, permit with conditions, or exclude. Whether a given activity may lawfully occupy a given lot reads from these tables: find the use's group, then check the district's treatment of that group.
The classifications are periodically reorganized by text amendment, so the current text governs any real determination. For property analysis, use questions surface most often at conversion (does the new use belong to a permitted group?) and in enforcement records (a use violation usually means an activity outside the district's menu, or one operating without its required conditions).
