I'm designing a project that involves a historic building listed on [NATIONAL REGISTER/LOCAL LANDMARK]. Proposed work: [DESCRIBE]. Help me: 1) Identify which Secretary of Interior Standards apply to this work (Preservation/Rehabilitation/Restoration/Reconstruction), 2) Which of my proposed changes are likely to be approved vs. challenged, 3) How to document existing conditions for the SHPO submission, 4) Alternative design approaches that achieve my goals while meeting Standards, 5) What tax credits (federal 20%, state credits) might be available and their implications. My state: [STATE].
