Denver Setbacks & Height Limits — Residential Zones

Fact-checked against the current Denver Zoning Code on September 20, 2026.

Denver does not use one citywide residential setback or height number. The Denver Zoning Code is form-based, so the applicable dimensions depend on the zone district, the building form, the zone-lot width, and sometimes the location of the building within the lot.

How Denver's Dimensional Rules Work

The zoning code regulates four main setback directions:

• Primary street — the street frontage designated as the primary street for the zone lot
• Side street — a second street frontage on a corner or multiple-frontage lot
• Side interior — an interior side zone-lot line
• Rear — the rear zone-lot line

For many residential building forms, the code also regulates maximum height separately in the front and rear portions of the lot and applies a sloping bulk plane from side lot lines.

E-SU-D Urban House Example

E-SU-D is a useful example because it is a common Urban Edge single-unit district, but these numbers should not be copied to a different zone or building form.

For the Urban House building form in E-SU-D, the current Article 4 standards include:

The previous version of this page treated 20 ft as a universal front setback. That is not accurate under the current Urban House table: for E-SU and other listed districts, the primary-street setback is calculated under the code's block-sensitive setback rules in Section 13.1.5.9.

The side setbacks also change with lot width. Under the Urban House table, side-interior setbacks are 3 ft on lots 30 ft wide or less; 3 ft minimum on one side with 10 ft combined on lots over 30 ft through 40 ft; 5 ft on lots over 40 ft and under 75 ft; and 10 ft on lots 75 ft or wider. Side-street setbacks likewise vary by lot width.

Height and Bulk Plane

For the Urban House form, Article 4 divides the lot depth into a front 65% and rear 35%:

• Base maximum height is 30 ft in the front 65% and 17 ft in the rear 35%.
• In the front 65%, the code permits a height increase of 1 ft for every 5 ft of zone-lot width over 50 ft, up to 35 ft.
• In the rear 35%, the code permits a height increase of 1 ft for every 3 ft of additional side setback, up to 19 ft.

The bulk plane is separate from those maximum-height limits. For the Urban House form, the current table uses vertical bulk-plane heights of 17 ft in the front 65% and 10 ft in the rear 35%, with a 45-degree slope from the side-interior and side-street zone-lot lines.

A design therefore has to satisfy both the absolute height limit and the bulk-plane envelope.

Other Residential Zones and Building Forms

Do not apply the E-SU-D Urban House values to every Denver house. Suburban, Urban, General Urban, Two Unit, Row House, Multi Unit, and detached accessory building forms have their own standards. Even within one form, the required side setbacks and permitted building coverage can change with lot width.

Detached garages, accessory structures, and accessory dwelling units also have separate building-form standards. For ADU-specific rules, use the Denver ADU rules page and confirm the applicable form in the current zoning code.

Exceptions, Projections, and Overlays

Required setbacks are not always identical to the distance from every roof edge, stair, porch, mechanical unit, or other feature. The Denver Zoning Code contains separate rules for permitted encroachments and exceptions.

Historic districts, design overlays, conservation overlays, and other special rules can also affect a project. A zoning-map lookup is only the first step; the project must be checked against the standards for the exact district and building form.

How to Check a Property

1. Find the parcel's current zone district using Denver's official zoning map.
2. Identify the building form that applies to the proposed project.
3. Open the corresponding neighborhood-context article in the Denver Zoning Code.
4. Read the height, siting, setback, bulk-plane, and accessory-structure rows for that form.
5. Check Section 13.1.5.9 when the table calls for a calculated primary-street setback.
6. Check overlays, landmark status, and any recorded or site-specific limitations before relying on the base table.
