To request a Certificate of Appropriateness (COA) review, submit a COA application form. Information on the review process and submittal requirements are listed on the application form, located on the Certificate of Appropriateness web page.
A COA application can be submitted before a building permit is applied for, or at the same time. For larger projects, it is recommended to obtain COA approval before preparing construction drawings for building permit.
In most cases, a COA can be obtained within the same time frame as a building permit. This is usually two to three weeks, depending on the nature of the proposed work.
