Document the condition
Note location, timing, weather relationship, changes over time, and any previous work. Photos and simple measurements can improve the first conversation.
Read the local context
Two checks shape the project before any design work. What the footings will sit in -- clay heaves and holds water, sand offers less lateral resistance, and near the fall line you can encounter either on the same lot -- so the soil should be established rather than assumed from the neighborhood. And what the ledger will attach to, which on an older in-town house needs to be uncovered and looked at. Note the pine canopy overhead too, since heavy shade and dropped needles decide which decking materials are worth considering here.
Ask what will be hidden
A good deck scope coordinates layout, setbacks, permits, foundations, framing, ledger flashing, stairs, guards, and material movement. The written scope should explain the preparation and verification that will no longer be visible at completion.
Compare complete scopes
Look for protection, access, materials, permits, testing, cleanup, restoration, exclusions, warranties, and change-order rules.
What official local sources add
Designation is the record that reaches a deck. On a designated property, a structure visible from the street can attract review touching material, railing style and proportion rather than merely size, and that applies to a defined set of parcels rather than to a neighborhood's general appearance -- so the answer is address-specific. The stormwater and drainage side matters through the ground instead: excavation for footings is site disturbance, and a recorded easement crossing the back of a lot can rule out the obvious location before any design work begins.
