Council approves MU3 workforce-housing zoning with pledge to codify unit-replacement protections

Charleston City Council on March 24 approved a new MU3 zoning district intended to encourage mixed-use developments that combine market-rate and affordable housing.

Former Council Member Jackson urged the council to add a clear, codified special condition guaranteeing a one-to-one replacement of public-housing units when properties are rezoned as part of Project 3500. "We need an additional special condition clause in this ordinance that defines and codifies the exact one-to-one units replacement guarantee for every PHA property when it's rezoned," Jackson said.

Staff answered technical questions about parking eligibility and whether AMI levels and mixed-income dispersal rules are controlled by the amendment or by the base zoning code. Mr. Martin and Christopher Morgan explained that provisions addressing scattered and mixed-income housing exist in the city's base zoning code and that the draft MU3 amendments amend the base language rather than recreate all base-code provisions.

Council members agreed to incorporate language clarifying replacement commitments and to finalize guiding principles for Project 3500 between first and second reading. Councilman D'Alessandro described the MU3 district as a potential national model for mixed-use workforce housing, stressing design and resident protections.

The ordinance was approved on voice vote with the council directing staff to codify unit-replacement protections and confirm AMI levels consistent with HUD RAD guidance where relevant. Additional implementation details on unit mix and review authority will be handled through follow-up ordinance language and administrative guidance.
