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
Begin with the slope and the wall. How far the ground drops across the intended footprint determines whether this is a simple platform or an elevated structure with real bracing and guard requirements, and it is the single biggest driver of what the project costs. What the ledger will attach to matters just as much, and on an older house that has to be uncovered rather than assumed. If the property is in one of the newer subdivisions, pull the plat as well, since recorded easements frequently run exactly where a deck would naturally go.
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
District review is the record most likely to apply, and it applies by address. On a designated property in the mill-and-rail core, a structure visible from the street can attract review touching material, railing style and proportion rather than merely size. The floodplain resource matters where a parcel is mapped, since that can govern whether and how a structure may be placed at all -- a siting question best answered before design rather than after. Stormwater requirements reach a deck lightly, though footing excavation is still ground disturbance.
