2. Develop a preservation plan: Once the survey and assessment are complete, a preservation plan should be developed. This plan should outline the specific actions and methods that will be used to preserve the building, including any necessary repairs or restoration work. It is important to consult with experts in historical preservation to ensure that the plan is comprehensive and effective. 3. Obtain necessary permits and approvals: Before any work can begin on a historical building, it is essential to obtain the necessary permits and approvals from local authorities. This may include zoning permits, building permits, and approvals from historical preservation boards. Failure to obtain the necessary permits can result in costly fines and delays in the preservation process.
