Safety comes first.
Do not enter or continue work in an unsafe structure. Fire, gas, electrical, structural, sewage, or immediate danger comes before preservation planning. Use emergency services and qualified professionals as appropriate.
Common questions
Clear answers to get started.
Confirm dates, rights, and requirements with the responsible agency or qualified professional.
Does old mean historic?
No. Age, a National Register listing, local zoning, an individual landmark, and other overlays are different.
What is a COA?
A Certificate of Appropriateness is the City’s historic-review approval for work within its authority. Ask OHP whether the specific project needs one.
Does every project go to a board?
No. Some work may receive staff review while other scopes can require board consideration. OHP confirms the route.
Is historic approval the same as a permit?
No. Historic review, zoning, building permits, utility approvals, and inspections can be separate.
What if work already started?
Pause additional work, preserve photos and documents, and contact OHP promptly for the correction route.
Next step
Check the property. Confirm the route. Approve before you build.
Use the free tool first. If you later want to discuss selling the property in its current condition, that conversation is optional and separate.
