Summary
In unincorporated Story County, renovating or repurposing a building on the National Register of Historic Places, or a structure designated a local landmark contributing to a historic district, is a conditional use requiring Board of Adjustment approval under the Land Development Regulations. The work may not destroy or obscure the building's essential architectural features, which must instead be enhanced to the extent feasible and prudent.
9. Adaptive Reuse. The renovation and remodeling of structures on the National Register of Historic Places for adaptive reuse may not destroy or obscure essential architectural features. In addition, such architectural features must be enhanced to the extent that it is feasible and prudent to do so.
Full Breakdown
Table 90-1 of the Land Development Regulations (Chapter 90, Conditional Uses) lists "adaptive reuse of abandoned schools, churches or buildings or other structures listed on the National Register of Historic Places or those designated as local landmarks that contribute to a historic district" as a use marked "CS": a conditional use to which supplemental standards apply, across the A-1, A-2, A-R, R-1, R-2, RMH, C-LI, HI and GBC zoning districts. 08(9) supplies that supplemental standard: renovation and remodeling of a National Register structure for adaptive reuse may not destroy or obscure essential architectural features, and those features must be enhanced to the extent it is feasible and prudent to do so.
02, a conditional use permit is issued only after the Board of Adjustment reviews and approves the submitted application and plan; the permit is issued in the applicant's name, incorporates the approved plan by reference, and is recorded with the County Recorder, and all development must proceed strictly as approved. Enforcement of the Land Development Regulations (Chapters 85 through 92, which includes Chapter 90) runs through Chapter 93: the Planning and Development Office investigates a reported violation, and if one exists issues a written Notice of Violation giving 30 days to correct or submit an approved compliance schedule.
The notice can be appealed to the Board of Adjustment within 30 days. 00 for each repeat offense, with each day a violation continues after the compliance date treated as a separate offense.
Violations & Fines
Reusing a National Register or landmark-designated structure without the required conditional use permit, or altering it in a way that destroys or obscures essential architectural features, is enforced under Chapter 93. The Planning and Development Office investigates and issues a Notice of Violation allowing 30 days to correct or propose a compliance schedule, appealable to the Board of Adjustment within 30 days. An unresolved violation becomes a County infraction carrying a civil penalty up to $750.00 for a first offense and up to $1,000.00 for each repeat offense, with each continuing day a separate offense (Iowa Code Section 331.307[1]).
