What the Milan code indicates by district
The table below shows how each district treats ADUs, alongside the lot and setback standards that govern a second unit. District boundaries and conditions vary, so treat this as a starting point and confirm the district that applies to your parcel.
| District | Min lot | Setbacks F / S / R | Max height | ADU |
|---|---|---|---|---|
| Very-Low-Density Agricultural | 5 ac | 85 / - / 50 ft | 35 ft | Special permit |
| Agricultural | 3 ac | 85 / - / 35 ft | 35 ft | Special permit |
| Low-Density Residential | 2 ac | 75 / 10 / 25 ft | 35 ft | Special permit |
| Hamlet | 1 ac | 20 / 0 / 25 ft | 35 ft | Special permit |
| Highway Business | 1 ac | 80 / 20 / 50 ft | 35 ft | Special permit |
| Land Conservation | 1 ac | 80 / - / 50 ft | — | No |
Very-Low-Density Agricultural — The schedule's side-yard column is headed "Minimum side yard (BOTH)", so the figure is the total across the two side yards, not the requirement on each. No minimum is published for the narrower of the two on its own, so the single-side figure is left empty rather than guessed; the combined figure is the requirement. Front yards are measured from the front lot line, or from the boundary of the road where the premises description extends into the road (Note 4). Roofs must have a pitch of at least 7 in 12 (Note 10).

No minimum is published for the narrower of the two on its own, so the single-side figure is left empty rather than guessed; the combined figure is the requirement. Front yards are measured from the front lot line, or from the boundary of the road where the premises description extends into the road (Note 4). Roofs must have a pitch of at least 7 in 12 (Note 10). The lot width applies except as elsewhere specified (Note 1).
Low-Density Residential — Table B publishes TWO complete columns for R2A, "Dwellings" and "Nondwellings". The base row here is the dwellings one. A non-dwelling use on the same land takes a 100 ft front yard, 60 ft of combined side yard and a 50 ft rear yard. The schedule's side-yard column is headed "Minimum side yard (BOTH)", so the figure is the total across the two side yards, not the requirement on each. Note 8 adds a floor on the narrower of the two: it may not be less than 1/3 of that total. Front yards are measured from the front lot line, or from the boundary of the road where the premises description extends into the road (Note 4). Roofs must have a pitch of at least 7 in 12 (Note 10). On a through lot the front yard requirement is observed on BOTH streets (Note 5).
Hamlet — The schedule's side-yard column is headed "Minimum side yard (BOTH)", so the figure is the total across the two side yards, not the requirement on each. HA is the one district that states both halves: the schedule prints "0/20", so one side yard may be zero provided the two together come to 20 ft. Front yards are measured from the front lot line, or from the boundary of the road where the premises description extends into the road (Note 4). Roofs must have a pitch of at least 7 in 12 (Note 10).
Highway Business — The schedule's side-yard column is headed "Minimum side yard (BOTH)", so the figure is the total across the two side yards, not the requirement on each. Note 8 adds a floor on the narrower of the two: it may not be less than 1/3 of that total. Lot width is 200 ft on an interior lot and 240 ft on a corner lot, measured at the front building line (Note 3). A group of establishments needs 5 acres and 400 ft of width rather than the single-lot figures. Parking is separately set back: no parking space may come within 20 ft of any property line (Note 9). Nothing may encroach into the front yard except a fence or wall no more than 6 ft high, or a sign no larger than 20 sq ft (Note 6). For a COMMERCIAL use the coverage calculation excludes impervious surfaces intended for pedestrian access, vehicle access, vehicle parking and loading (Note 11), so the 10% cap bites only on buildings. Light industrial uses — laboratory, research and non-nuisance manufacturing — take their bulk requirements from § 200-32 instead (Note 2). Front yards are measured from the front lot line, or from the boundary of the road where the premises description extends into the road (Note 4). Roofs must have a pitch of at least 7 in 12 (Note 10).
Land Conservation — The schedule's side-yard column is headed "Minimum side yard (BOTH)", so the figure is the total across the two side yards, not the requirement on each. No minimum is published for the narrower of the two on its own, so the single-side figure is left empty rather than guessed; the combined figure is the requirement. Table B publishes NO maximum height for LC — the height row simply stops at HB — so the height here is empty rather than assumed. No automobile parking area may encroach into the front, side or rear yards (Note 7). Front yards are measured from the front lot line, or from the boundary of the road where the premises description extends into the road (Note 4). Roofs must have a pitch of at least 7 in 12 (Note 10).
