Pittsburgh Setbacks & Height Limits — Residential Zones

Fact-checked against Pittsburgh Ordinance No. 10 of 2025 and current City Planning materials on September 21, 2026.

Pittsburgh's residential standards combine a use subdistrict such as R1D, R1A, R2, R3, or RM with a development subdistrict that controls lot size, setbacks, and height.

The previous page's one-table comparison of “R1D-H / R1A / R2” omitted this structure and used stale 35-ft height limits.

2025 Minimum-Lot-Size Amendment Is in Effect

Pittsburgh City Council adopted Bill 2025-1579 in May 2025. It became Ordinance No. 10, effective May 7, 2025.

The amendment reduced minimum lot sizes and revised Chapter 903 residential development-subdistrict standards citywide.

A saved pre-May-2025 lot-size table should not be used.

Height for R1D / R1A / R2 / R3

Under the adopted 2025 Chapter 903 text, the maximum principal-building height for R1D, R1A, R2, and R3 is generally:

40 ft, not to exceed 3 stories

across the residential development-subdistrict tables.

The previous page's blanket 35-ft R1D/R1A/R2 limit is therefore stale.

RM uses a different height framework and should be checked in the exact development subdistrict.

Setbacks Depend on Development Subdistrict

The setback table changes with development intensity.

Examples from the adopted 2025 text include:

Very Low Density

For R1D / R1A / R2 / R3:

• front: 30 ft;
• rear: 30 ft;
• exterior side: 30 ft;
• interior side: 5 ft;
• maximum height: 40 ft / 3 stories.

The current minimum lot size in this development subdistrict is 3,000 sq ft under the adopted amendment.

Very High Density

For R1D / R1A / R2 / R3:

• front: 5 ft;
• rear: 15 ft;
• exterior side: 5 ft;
• interior side: 5 ft;
• maximum height: 40 ft / 3 stories.

Other development subdistricts, including Moderate and High Density, use different dimensional values. Always use the complete zoning designation.

Contextual Setbacks and Contextual Height

Chapter 903 expressly allows qualifying new development to use Contextual Setbacks and Contextual Building Heights under §§925.06 and 925.07.

That can change the practical envelope from the base table on an established block.

Current ADU Proposal Is Not Yet the Same as Adopted Law

The previous page described local ADU rules such as “typically 3-ft side/rear setbacks and 20-ft height” as if they were already a settled current citywide standard.

Pittsburgh's current Housing Needs Assessment implementation page shows that the broader 2025–2026 legislation covering ADUs, parking, and affordable-housing bonuses remains in the legislative process as of this fact-check, with a City Council public hearing scheduled for September 23, 2026.

Do not treat the proposed ADU text as effective zoning until it is formally enacted.

See the Pittsburgh ADU rules page for the current status.

Hillside, Overlay, and Compatibility Rules

Environmental performance, residential compatibility, hillside, historic, riverfront, neighborhood overlay, and other rules can add standards beyond Chapter 903.

High- and very-high-density projects near protected residential property can face additional compatibility setbacks and height limits.

How to Check a Property

1. Confirm the full zoning designation, including use and development subdistrict.
2. Use current Chapter 903 as amended by Ordinance No. 10 of 2025.
3. Check whether contextual setbacks or contextual height apply.
4. Check compatibility, hillside, environmental, historic, and overlay rules.
5. Treat pending ADU legislation as proposed until enacted.
6. Confirm parcel-specific questions with Pittsburgh City Planning.
