Ogden, UT Zoning Overlays & Bonuses: Downtown Design Guide (2026)

Section 15-34-7 of Ogden's Downtown Commercial Zones chapter places the 25th Street Historic District under mandatory design review: external alterations or additions to any structure there, including new construction, additions, signs, awnings and facade renovation, must be reviewed by the Landmarks Commission using the standards and guidelines of City Code Title 17, the city's Landmarks title. That review runs alongside, not instead of, ordinary building-permit review. The section also caps how existing historic buildings can grow: a rooftop addition or new story is barred unless the applicant documents that removed floors are being restored to the original building's historic size, scale and design, or meets a stricter test where the addition is set back from the front building face and is invisible from pedestrian level, both from directly across the street and from the same-side sidewalk 300 feet in either direction (any vacant lot on that side is assumed to hold a hypothetical 25-foot building for the sightline check).

Landmarks review in the district sits inside the C-9 "Nine Rails Creative District" framework, where section 15-34-8 separately requires new multifamily or 2,000-square-foot-plus commercial projects to fund public art equal to at least 1% of building valuation. Title 17 is administered by the Landmarks Commission created under section 17-1-3, with enforcement and penalty authority set out in section 17-1-8.
