Pool & Spa permits · Maryland

Where Maryland builds pools, permit by permit.

A pool permit is a commitment already made, and it arrives with decking, fencing, and electrical filings around it. Tradewinds observes them in county permit records, tied to the property behind each filing.

Active pool permits

The clearest signal: a pool permit filed this week means work is starting on that parcel now.

🪜

Decking and hardscape

Pool builds pull deck and patio filings on the same parcel, usually within the same season.

🔒

Barrier and fence work

Code requires a barrier, so a fence permit on a pool parcel is a scheduled, non-optional job.

Pool electrical

Bonding, pumps, and heaters mean a licensed electrical filing that names another firm on the same job.

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.
