Permit requirements vary depending on the type of permit being obtained. Generally, plans are not required to replace an electric service, water heater, furnace.
If the permit is for new windows, new siding, a re-roof or exterior remodel and the home is located in a Historic District Overlay, the Planning Division will require plans and/or other documentation to show that the proposed work will maintain the historic integrity of the house.
If a historic home is not located in a Historic Preservation District, you are not required to maintain the historic integrity of the house, however it is strongly encouraged.
Plans are required for additions and major remodels.
It depends on the location of the historic house. You’d need to contact your local planning department. Typically cities are more concerned about the aesthetics of exteriors than interiors. Before you remodel, I suggest you do lead testing and then hire an EPA lead safe certified contractor. Learn more about it here: http://www2.epa.gov/lead/renovation-repair-and-painting-program
It depends what you’re doing to the exterior and what the local building departments require. In some area’s there is no permit required to change siding in other area’s a permit is required. So check with your local building dept.
Also, if the home is Historic, then you need to consult with the local Historical Society. They will inform you what you can and can not do in order for the home to maintain it’s status.
