  1. Confirm the authority

    Identify the current preservation office or review body for the exact property.

  2. Ask what documentation is required

    Obtain the applicable standards, application, photographs, drawings, product details, and review sequence.

  3. Compare repair and replacement

    Show the condition evidence and why each proposed scope retains or changes significant features.
