The following tables specify the activity status of activities in the Historic Heritage overlay. Where there is a conflict between the activity table in the underlying zone and the activity table within the scheduled historic heritage place overlay, the activity table in the latter takes precedence.

There are additional activity controls below in activity table 2 and 3, for scheduled historic heritage places subject to archaeological controls or controls for historic heritage areas. If a rule in table 2 is more onerous than the same activity rule in activity table 1, it takes precedence over the rule in activity table 1. Where there is a conflict between the activity table for a scheduled historic heritage area table 3 and the activity table for an individually scheduled historic heritage place table 1, the latter takes precedence.

Where the extent of place entry for a scheduled historic heritage place is annotated with a # in the schedule, no geographic extent has been delineated for the place. In these cases the rules in activity tables 1 and 2 apply to all land or water within 50m of any feature identified in the schedule of historic heritage places with a #, refer to appendix 9 and the planning maps.

The controls in activity table 1 apply to building interiors unless specifically identified in the exclusions column in the schedule of historic heritage places.

Refer to the Historic Heritage overlay - objectives and policies description for explanations of following terms: conservation, demolition or destruction, dismantle, setting, place, maintenance, fabric, features and restoration.

1. The maintenance and repair of buildings and structures identified in the schedule of historic heritage places (excluding features identified in the exclusions column) must:

c. not involve the use of scaffolding affixed to the building or structure

d. not result in a change to the design, texture, or form of the fabric

e. not result in a change to the extent, floor levels, location of internal walls, form, proportion and scale of the building or structure
