What does UMX zoning mean?
The Urban Mixed-Use district (UMX) is a mixed-use zoning classification in the City of Madison Zoning Code (Chapter 28). Properties in this district are subject to density, height, lot coverage, and use restrictions specific to UMX.
Development potential in UMX
The minimum lot area per dwelling unit is 600 sq ft. On a typical 5,000 sq ft lot, this allows up to 8 units by density alone. An FAR limit of 5 may further constrain total floor area.
Maximum building height: 130 feet (10 stories). Maximum lot coverage: 85% — the total footprint of all buildings cannot exceed this share of the lot.
ADU eligibility in UMX
No — UMX is not on the list of ADU-eligible zoning districts.
