Get the details down first
Note layout, sun patterns, drainage, and what's already built. Photos and rough measurements help from the start.
Read the local context
Rockford's yards range from tight, mature lots in river-adjacent neighborhoods like Haight Village to the broader, newer-subdivision yards ringing the city. The Rock River's flood record, a hard freeze-thaw winter cycle, and mature tree cover all shape footing depth, drainage, and material choices before a deck design is finalized.
Ask what won't be visible later
A sound scope walks through layout, setbacks, permitting, footing depth given the freeze-thaw cycle, ledger flashing, stairs and guards, and how materials get onto the site. A written scope should explain the prep and verification steps that disappear once the job looks finished.
Compare the whole scope
Check protection measures, access, materials, permits, testing, cleanup, restoration, exclusions, warranty, and change orders.
What official local sources add
This is the trade where Rockford's exemption is worth knowing precisely: detached accessory structures under 120 square feet — which includes small decks — are the main exception to the city's general permit requirement. That is roughly a ten-by-twelve footprint, so it is a real threshold that a modest deck can sit under and a family-sized one cannot. Note the word detached: a deck attached to the house is a different proposition, and anything above the threshold goes through residential plan review at Construction & Development Services like any other structure.
