What are the setback requirements in Saint Paul R1 zones?

In R1 One-Family Residential, Saint Paul requires a front setback of approximately 20 ft, interior side setbacks of 5 ft, and a rear setback of 25 ft. R2-R4 zones use similar front/rear numbers with slightly smaller side setbacks. Verify your exact zone on the Saint Paul zoning map before designing.

What is the maximum building height in Saint Paul residential zones?

Maximum building height in Saint Paul R1-R4 single-family zones is typically 30 ft, measured from average grade to the midpoint of a pitched roof. RT two-family districts use the same 30 ft cap, while RM multi-family districts allow up to 45 ft.

Are corner lots treated differently in Saint Paul?

Yes. Corner lots have two front yards — one along each street frontage — and must meet the front setback on both streets. The remaining two yards are treated as interior side and rear, though the rear yard is usually opposite the primary front.

Do state ADU rules override Saint Paul setback limits?

No. Minnesota has no statewide ADU preemption law as of 2026-05. Saint Paul's local zoning code (Chapter 65) is the sole source for ADU setback and dimensional standards. Confirm current rules with the Saint Paul Department of Safety and Inspections.

Saint Paul Setbacks & Height Limits — Residential Zones

Fact-checked against Saint Paul's current 1–6 Unit Housing zoning materials, last updated through 2026.

Saint Paul's lower-density residential zoning changed substantially in 2023. The previous page's R1–R4 table is obsolete.

The current lower-density residential districts are RL, H1, and H2, created or revised through the City's 1–6 Unit Housing zoning amendments that took effect November 26, 2023.

Current Base Standards

The City's current district pages provide:

Standard	RL	H1	H2
Minimum lot area per principal unit	9,000 sq ft	1,500 sq ft	1,000 sq ft
Minimum lot width	60 ft	30 ft	25 ft
Maximum principal units per lot	2	4	5
Maximum building height	35 ft	35 ft	39 ft; 36 ft for flat or shed roofs
Front setback	30 ft	10 ft	10 ft
Side setback	10 ft	5 ft	5 ft
Rear setback	10 ft	10 ft	10 ft
Maximum lot coverage	40%	45%	50%

The previous page instead described R1–R4 as the current low-density districts with a generic 20-ft front / 4–5-ft side / 25-ft rear / 30-ft height pattern. Those district names and dimensions are no longer current.

Front-Yard Context Rule

For H1 and H2, the City explains that the 10-ft district minimum can be increased on a substantially built-up block where adjoining principal buildings have larger front setbacks.

The current rule uses a midpoint formula between the district standard and the applicable adjoining setback.

Therefore, a 10-ft H1 or H2 front yard is not always the final required line.

Density Bonus

Saint Paul allows qualifying H1/H2 projects to receive additional principal units and other benefits through the City's density-bonus provisions.

For example:

H1 ordinarily allows up to four principal units, with up to two additional qualifying bonus units.
H2 ordinarily allows up to five principal units, with up to one additional qualifying bonus unit.

Projects using bonus provisions still must satisfy the other applicable dimensional and design standards unless the bonus rule expressly modifies them.

Accessory Buildings and ADUs

Accessory-building height and setbacks are governed separately by Chapter 63. ADUs do not count toward the H1/H2 maximum number of principal units, but they remain subject to the City's ADU and accessory-building standards.

Other Districts and Overlays

RM, Traditional Neighborhood, business, Ford, river-corridor, historic, and airport-related districts use different standards.

Do not apply the RL/H1/H2 table to a parcel in another zoning district.

How to Check a Property

Confirm whether the parcel is RL, H1, H2, or another district.
Use the current district page and Chapter 66.
Check the front-yard context rule.
Determine whether a density bonus applies.
Check accessory-building, ADU, historic, river-corridor, and airport rules separately.
Confirm parcel-specific questions with Saint Paul Planning.
