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
Livonia blends 1950s-1960s ranch-subdivision yards -- Clements Circle, SMB Estates -- inside the Rouge River's Middle Branch watershed (Bell Branch, Tarabusi Creek, Newburgh Lake) with newer construction farther from the older core. A seasonal high water table, real freeze-thaw winters, and a housing stock now 60-plus years old in many neighborhoods reward careful footing and drainage planning before scope.
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
The Guide to Development is the practical document for this trade, because it is where site-plan and permitting expectations are actually spelled out -- and a deck is a permitted structure with setback, footing and guard requirements rather than a weekend project. Floodplain status through the FEMA mapping the city points to matters on the smaller number of parcels it reaches, where it can govern whether and how a structure may be placed at all. The Vision 21 plan itself operates above the level of an individual lot. What it does not cover is the constraint that decides most designs here: frost depth.
