I'm interested in interesting approaches local governments, particularly via zoning and land-use planning, are taking towards encouraging adaptive reuse of their existing building stock. What changes are you/they making in codes? Are you/they using incentives or credits? What are the goals and motives? Problems? What conditions are you dealing with?
I'm working on a case study of the City of Los Angeles' Adaptive Reuse Ordinance (ARO) which allowed historic commercial and light industrial buildings in the struggling central downtown business district to be converted to residential and residential/live-work/retail. The ARO encouraged preserving the existing built structures by relaxing seismic codes, mandating only that the existing amount of parking be maintained (exemption from existing city minimum parking requirements for housing units), and by providing a by-right process for permitting these types of buildings rather than requiring variances.
I've found quite a bit about LA's program, but I'd love to get some other perspectives or leads on the issue.
