Minneapolis Zoning Codes Explained: UN1 Through UN4

Minneapolis rewrote its zoning code as part of the Minneapolis 2040 Comprehensive Plan — one of the most aggressive upzoning efforts any major U.S. city has undertaken. The old RS1/RS2/R1/R2/R3 categories were replaced with a new system built around density and mixed use.

If you're buying, developing, or just trying to understand what a piece of Minneapolis land can do, the Urban Neighborhood (UN) zone it falls in is one of the most important numbers to know.

The Urban Neighborhood Tiers

UN1 — Low-Density Urban Neighborhood

The entry-level residential zone. Allows single-family homes, duplexes, and small-scale attached housing.

What you can typically build:

• Single-family homes
• Duplexes and twin homes
• Small accessory dwelling units (ADUs)

Typical height: Up to 2.5–3 stories
Typical uses: Established single-family neighborhoods transitioning slowly to include more units

UN1 is the most restrictive Urban Neighborhood zone, but even here the 2040 Plan eliminated single-family-only zoning. Every UN1 lot can legally support a duplex. This was a significant shift from the old code.

UN2 — Urban Neighborhood 2

A step up in density. Allows 3–4 unit buildings and somewhat taller structures.

What you can typically build:

• Triplexes and fourplexes
• Small apartment buildings (3–6 units)
• Rowhouses and townhomes

Typical height: Up to 3–4 stories
Typical uses: Transitional neighborhoods, denser residential corridors

In my experience, UN2 is where a lot of the interesting infill opportunity lives right now. The underlying land values haven't fully caught up to the new entitlement, and a well-located UN2 lot near transit or amenities can support a project that would have required a variance five years ago.

UN3 — Urban Neighborhood 3

Medium-density residential. This is where you start seeing real apartment-scale development.

What you can typically build:

• Apartment buildings (no unit cap)
• Mixed-use buildings with residential above ground-floor commercial
• Live-work units

Typical height: Up to 4–6 stories
Typical uses: Denser urban neighborhoods, nodes around commercial corridors

UN3 is common along the main commercial corridors — Hennepin, Lyndale, Lake Street, Central Ave. If you find a vacant or underutilized lot zoned UN3, it's worth a serious look at the development math.

UN4 — Urban Neighborhood 4

The highest-density residential zone outside downtown. Designed for significant apartment and mixed-use development.

What you can typically build:

• Large apartment buildings
• Mixed-use with substantial commercial components
• Higher-density attached housing of all types

Typical height: Up to 6+ stories (varies by specific overlay)
Typical uses: High-activity nodes, areas near light rail stations, downtown-adjacent neighborhoods

UN4 is relatively rare and clustered around the most active transit and commercial areas. When you find a UN4 parcel at a reasonable basis, the development potential is substantial.

Beyond Urban Neighborhood: Other Codes You'll See

The UN series covers most of Minneapolis's residential land, but you'll also encounter:

CC1–CC4 (Community Corridor) — Commercial corridors with density based on intensity. CC3 and CC4 allow tall mixed-use. Think Nicollet Mall area, areas near light rail.

DT1–DT2 (Downtown) — Downtown and near-downtown zones with the least restrictions on height and use. High complexity, high capital requirements.

OR (Office-Residential) — Mixed office and residential, common in transitional areas near hospitals or universities.

I1–I3 (Industrial) — Light to heavy industrial. Increasingly attractive for adaptive reuse as manufacturing leaves urban areas.

BFC (Business/Flex Corridor) — Commercial and mixed-use along specific named corridors. Density varies by suffix (BFC20 through BFC100).

How to Check the Zone for Any Property

The fastest way is to look up the address on ParcelLens — it shows the current Minneapolis zoning code and a plain-English description of what it allows. The city's own zoning map is accurate but harder to navigate, especially on mobile.

If you're doing volume research across a neighborhood or corridor, the city also publishes GIS data that you can query.

What Zoning Doesn't Tell You

Zone tells you what's allowed, not what will pencil. A UN3 lot that allows 20 units might only support 8 if it's 4,000 square feet. And a property in a historic overlay district may face additional design review even for by-right projects.

The other thing zoning doesn't capture: what the neighbors will say. By-right development in Minneapolis doesn't require neighborhood approval, but understanding the local context still matters for your exit.
