Overview

Naming convention
letter-code
| residential | letter-numeric intensity-encoded (R-1 largest lot / lowest density → R-4 smallest lot / highest density; R-1S small-lot subvariant; RT-1/RT-2 townhouse variants) |
|---|---|
| commercial | letter-numeric intensity-encoded (C-1 neighborhood → C-3 highway) |
| industrial | letter-numeric intensity-encoded (I-1 light → I-2 general/heavy) |
Conventional euclidean zoning — not form-based, not hybrid-PD, not rewrite-in-flight, not no-zoning. District-code pattern is intensity-encoded letter-numeric (number indicates relative density / intensity, not lot-size-in-thousands). Not the INVERSE pattern. v1 classification (implicit euclidean) retained.

Qualifying condition
New Ulm city population 13,522 (2020 Census DP-1, carried forward from v1 profile). Threshold check per zoning/us/minnesota/preemptions.md: cities >=5,000 must allow duplexes and triplexes by-right in all SF zones. Arithmetic: 13,522 >= 5,000 → TIER A APPLIES. Metro Council tier check: New Ulm is in Brown County (southwest MN). Metropolitan Council jurisdiction covers only 7 counties: Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, Washington. Arithmetic: 'Brown' NOT IN {Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, Washington} → TIER B (quadplex) does NOT APPLY.
Effect
Duplexes and triplexes must be permitted by-right in all single-family residential zones (R-1, R-2, R-1S on New Ulm zoning map; possibly RT-1/RT-2 depending on classification). Minimum lot size for a duplex or triplex may not exceed the minimum lot size for a single-family home in the same zone. Off-street parking requirement capped at 1 space per unit (state cap).
