Build Siren watches building, mechanical, electrical and plumbing permits filed every day with Southeast Michigan building departments, then delivers the ones that match your trade — with the exact project address, the permit description, the estimated value where it is on file, the contractor or homeowner named on the filing, and a Premium / Strong / Usable lead score.
Pick your trade to see the permit types we track, how leads are scored, and the Metro Detroit cities we cover.

Why permit leads beat shared leads
Shared lead services sell the same homeowner’s contact form to four or five contractors who then race to the bottom on price. A building permit is different: it is a public record that a specific project at a specific address is really happening, it names who is involved, and most of your competitors never see it. Build Siren does the monitoring so you can spend that time bidding.
