Historic District Lighting Requirements

Certificate of Appropriateness

In Carmel's historic districts, property owners must obtain a Certificate of Appropriateness (COA) before making changes to light fixtures. This requirement applies to any "conspicuous change in the exterior appearance" of historic buildings or their appurtenances, including light fixtures.

Preservation of Character

The Commission evaluates whether proposed changes to lighting will preserve the historical and architectural character of the building or structure. This evaluation includes consideration of:

• Texture and materials of the fixtures
• Color compatibility with the historic structure
• Style and detailing alignment with architectural elements
• Visual compatibility with similar architectural features in the historic district

Maintaining Architectural Integrity

Light fixtures are considered important elements that contribute to a building's historical character. The regulations explicitly state that light fixtures "may be moved, reconstructed, altered, or maintained only in a manner that will preserve the historical and architectural character of the building."

General Exterior Lighting Standards

Preventing Light Trespass

One of Carmel's most straightforward lighting regulations states: "Any lights used for exterior illumination shall be directed away from adjoining public and private property." This requirement helps prevent light trespass and respects neighboring property owners' right to darkness.
