• When: August 26, 2024
• Address: 641 S Pearl St, Denver, CO 80209
• City: Denver
• State: CO
• Category: Spot Rezoning
• Subcategory: Residential Rezoning
• Size (SF): 6,250 square feet (0.14 acres)
• New Zoning: U-SU-B1 Detached Accessory Dwelling Unit (ADU)
• New Zoning Description: U-SU-B1 is a single-unit residential district that allows Urban House forms and permits a Detached Accessory Dwelling Unit (ADU) in the rear yard on zone lots of at least 4,500 square feet. The ADU form may be up to 1.5 stories or 24 feet in height and is intended to introduce modest residential density while maintaining the neighborhood character.
• Previous Zoning: U-SU-B (Single-Unit Residential)
• Previous Zoning Description: U-SU-B is a single-unit residential district that allows only an Urban House building form on a minimum zone lot of 4,500 square feet. It does not permit accessory dwelling units (ADUs).

The property at 641 South Pearl Street is currently zoned U-SU-B, which allows only single-unit residential use. The property owners seek to rezone it to U-SU-B1 to allow the construction of a Detached Accessory Dwelling Unit (ADU) in the rear yard. The subject property is located in Washington Park West and consists of a single-unit home built in 1890. The proposed rezoning aligns with the city's objectives to increase housing options while maintaining the neighborhood's character. The proposed ADU zoning will introduce modest residential density while preserving the primary building's form and scale.

Why it Matters

This rezoning will allow for the addition of an accessory dwelling unit (ADU), contributing to the city's goals for affordable housing and providing more housing options in a well-established, highly desirable neighborhood.
