Verify the property against city records
Use the City’s historic district maps and contact its historic preservation staff about the exact address, including possible individual designation. Describe which face or roof feature can be seen from the street. A nearby project, even on the same block, is a poor substitute for a property-specific answer.
Describe what would physically change
Give the existing and proposed material, shape, size, finish and position. Use a street-level photo showing the full roof outline and a view of the affected detail from a safe location. Replacing deteriorated mortar to match and removing a visible chimney feature are different proposals. Keep competing options on separate sheets.
Put the city review before the purchase
The City describes a Certificate of Appropriateness for work changing the exterior appearance of a designated historic property. It also describes administrative review for certain maintenance, repairs and in-kind replacements. Ask staff which route applies, what documents they need, and which building review follows. Keep that response with the contractor’s written scope before ordering a custom component.
