Pool permits

A pool build brings deck and patio filings with it, on the same parcel, in a predictable sequence.

🏡

New construction

Builders leave decking and outdoor living to the buyer, so new-construction parcels file their outdoor permits in year one or two.

📐

Additions and sunrooms

An addition changes the back of a house, and the deck that met the old footprint gets rebuilt to meet the new one.

📈

Older homes at high value

Homes built before 2000 often carry dated decks or none at all, and replacement timing shows in permit and property records.

Built from county permit filings. Not every filing names a trade cleanly, and counties differ in what they publish, so these counts reflect our coverage as much as the work happening on the ground.
