Examples of the Standards & Guidelines being applied or not
15
1. Conserve the heritage value of a historic place. Do not remove, replace, or substantially alter its intact or repairable character- defining elements. Do not move a part of a historic place if its current location is a character-defining element.

Pacific Heights Co-op 1985 today

6. Protect and, if necessary, stabilize a historic place until any subsequent intervention is undertaken. Protect and preserve archaeological resources in place. Where there is potential for disturbance of archaeological resources, take mitigation measures to limit damage and loss of information. Ceperley Bldg & BC Yukon Chamber of MinesTerminus Hotel
34
Archaeological sites Fraser Arms Hotel, Vancouver
35
7. Evaluate the existing condition of character-defining elements to determine the appropriate intervention needed. Use the gentlest means possible for any intervention. Respect heritage value when undertaking an intervention. BeforeAfter cleaning
36
8. Maintain character-defining elements on an on-going basis. Repair character-defining elements by reinforcing their materials using recognized conservation methods. Replace in kind any extensively deteriorated or missing parts of character-defining elements, where there are surviving prototypes. Princess Avenue, Strathcona
37
9. Make any intervention needed to preserve character-defining elements physically and visually compatible with the historic place, and identifiable upon close inspection. Document any intervention for future reference. Barclay Manor, West End
