Indiana Code Title 36. Local Government § 36-7-11.1-10

Sec. 10. (a) If the commission determines that the proposed construction, reconstruction, alteration, or demolition will be appropriate, the secretary of the commission shall forthwith issue to the applicant a certificate of appropriateness.

(b) The commission may impose any reasonable conditions, consistent with the historic preservation plan, upon the issuance of a certificate of appropriateness, including the requirement of executing and recording covenants or filing a maintenance or performance bond.  If the commission determines that a certificate of appropriateness should not be issued, the commission shall forthwith place upon its records the reasons for the determination and may include recommendations respecting the proposed construction, reconstruction, alteration, or demolition.  The secretary of the commission shall forthwith notify the applicant of the determination transmitting to the applicant an attested copy of the reasons and recommendations, if any, of the commission.

(c) A final determination of the commission upon an application for certificate of appropriateness is subject to judicial review in the same manner and subject to the same limitations as a final decision of a board of zoning appeals under IC 36-7-4.  However, notwithstanding IC 36-7-4-1609, upon notice of the filing of the petition for judicial review, all proceedings and work on the subject premises are automatically stayed.
