Buildings on the Market Street Mall, between Fourth and Ninth Streets, must have facade, sign, and renovation work approved by the city's Design Review Commission before a permit issues.

The distinguishing original qualities or character of a building, structure, or site and its environment, where still in existence, shall not be destroyed. The removal or alteration of any historic material or distinctive architectural features shall not take place without the consent of the design review commission.

Full Breakdown

The Market Street Mall improvement district covers all properties fronting the mall from Fourth to Ninth Streets. Licenses and Inspections inspects each building and reports required repairs; owners then get 180 days to submit facade, sign, and rehab designs to the Design Review Commission, which must approve them before a building permit can issue. Standards protect original architectural character and bar removing distinctive features without commission consent. Owners get two years to start and three years to finish mandated work, with a financial-hardship exception.

Violations & Fines

Failing to submit designs within 180 days (or 90 days after a resubmission request), or ignoring a commission order, is a separate offense for each day, fined not less than $25.00 nor more than $100.00 per day.

Frequently Asked Questions

Does this apply to interior changes?
No. It governs exterior facades, storefronts, upper floors, and signs facing the Market Street Mall; interior work and legal use classifications stay under the regular zoning code.
Can I skip commission review for basic upkeep?
Yes. Ordinary maintenance or repair that doesn't change design, material, color, or outward appearance is exempt from Design Review Commission approval under Sec. 42-523.
What if repairs are too expensive?
Owners can seek a financial-infeasibility exception, costs over 50% of market value (owner-occupied) or over five years' estimated rent (rented), and submit an alternate design instead.
