§ 170-8. Maintenance; removal of dangerous conditions.

A. 

Every owner or other person in charge of a landmark building or structure or a building or structure in an historic district shall keep in good repair all of the exterior portions of such improvements and all interior portions thereof which, if not so maintained, may cause or tend to cause the exterior portions of such improvements to deteriorate, decay or become damaged or otherwise to fall into a state of disrepair.

B. 

In any case where the Building Official shall order or direct the construction, removal, alteration or demolition of any improvement on a landmark site or in an historic district for the purpose of remedying conditions determined to be dangerous to life, health or property, nothing contained herein shall be construed to make it unlawful for any person, without prior issuance of a certificate of appropriateness, to comply with such order or direction. The Building Official shall give the Historical and Landmark Review Board notice of any such proposed order or direction, and the Board shall have the power to require that the work not materially change the exterior appearance where the danger of life, health or property may be abated without detracting from the exterior appearance.

C. 

Nothing in this chapter shall be construed to prevent the ordinary maintenance or repair of any exterior architectural feature of any structure, whether a landmark or within an historic district or otherwise, which does not involve a change in design, material, color or outer appearance thereof.
