Many owners are unable to find economically feasible repair strategies. While commercial tenants avoid 5 hazardous buildings, residential tenants are often even less willing to pay a premium for strengthened premises. Consequently, more expensive repair options in that context can become unviable. Owners unable to find economically 6 viable repair strategies for heritage buildings are also forbidden from tearing them down. 3 RESEARCH NOTE Barring those more systematic changes, there are other measures Council could undertake that would mitigate the burden it imposes on the owners of heritage buildings. We detail these at the end of this report. The Final Report of the Canterbury Earthquakes Royal Commission argued that securing dangerous buildings “should not be impeded by the consent process and that life safety should be a paramount consideration for all buildings, regardless of heritage status.”3 Deloitte explored some potential Under such an approach the public They recommended specifically that policy responses in their submission benefit derived from the heritage where demolition or protective works on Wellington’s Long Term Plan (www. status is funded by the public.
