Connecticut General Statutes Title 7. Municipalities § 7-147f. Considerations in determining appropriateness. Solar energy systems

(a) If the commission determines that the proposed erection, alteration or parking will be appropriate, it shall issue a certificate of appropriateness. In passing on appropriateness as to exterior architectural features, buildings or structures, the commission shall consider, in addition to other pertinent factors, the type and style of exterior windows, doors, light fixtures, signs, above-ground utility structures, mechanical appurtenances and the type and texture of building materials. In passing upon appropriateness as to exterior architectural features the commission shall also consider, in addition to any other pertinent factors, the historical and architectural value and significance, architectural style, scale, general design, arrangement, texture and material of the architectural features involved and the relationship thereof to the exterior architectural style and pertinent features of other buildings and structures in the immediate neighborhood. No application for a certificate of appropriateness for an exterior architectural feature, such as a solar energy system, designed for the utilization of renewable resources shall be denied unless the commission finds that the feature cannot be installed without substantially impairing the historic character and appearance of the district. A certificate of appropriateness for such a feature may include stipulations requiring design modifications and limitations on the location of the feature which do not significantly impair its effectiveness. In passing upon appropriateness as to parking, the commission shall take into consideration the size of such parking area, the visibility of cars parked therein, the closeness of such area to adjacent buildings and other similar factors.

(b) In its deliberations, the historic district commission shall act only for the purpose of controlling the erection or alteration of buildings, structures or parking which are incongruous with the historic or architectural aspects of the district. The commission shall not consider interior arrangement or use. However, the commission may recommend adaptive reuse of any buildings or structures within the district compatible with the historic architectural aspects of the district.
