(3) The commission shall determine whether the proposed construction, reconstruction, alteration, restoration, moving, or demolition of buildings, structures, or appurtenant fixtures involved will be appropriate to the preservation of the historic district for the purposes of this subchapter, or whether, notwithstanding that it may be inappropriate, owing to conditions especially affecting the structure involved, but not affecting the historic district generally, failure to issue a certificate of appropriateness will involve a substantial hardship, financial or otherwise, to the applicant, and whether the certificate may be issued without substantial detriment to the public welfare and without substantial derogation from the intent and purpose of this subchapter.
