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 things about the property set the shape of this project. How far the ground falls across the footprint decides whether you are building a low platform or an elevated structure, and the taller it gets the more the guards, the bracing and the attachment back to the house govern the cost. What that attachment can actually fasten to is the second, and on an older cottage it needs to be uncovered and inspected rather than assumed. Note the canopy overhead too, since heavy shade decides which decking materials are worth considering.
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 most likely to matter, and it applies by address rather than by the look of a street. On a designated textile-era property, a structure visible from the front can attract review reaching material, railing style and proportion rather than merely size. The stormwater side reaches a deck less directly, since it adds little impervious surface, but excavation for footings is ground disturbance and a recorded easement crossing the back of a lot can rule out the obvious location before any design work begins. Pull the plat first.
