Built for
Permitline is for the people who lose nights waiting on a phone call from the GC: structural and MEP engineers, fire sprinkler contractors, land surveyors, asbestos and environmental testers, roofing and window suppliers, and permit expediters. If your pipeline is a rolodex, this is the same thing as a rolodex — except it writes itself.
See new builds and renovations the night the source feed publishes them.

How it works
Each permit goes from public open data to your inbox on the next morning's digest.
Our pipeline pulls permit records from two live open-data feeds: the DC Department of Buildings and the Montgomery County Department of Permitting Services. No human curation — every record from each source makes the cut.
Each permit is mapped to a single schema and classified by work type and jurisdiction, so it shows up the same way regardless of which field the upstream feed uses.
The public site serves whatever the nightly pull landed. Browse and filter by work type and time window — no account required.
A daily digest of saved-search matches goes to confirmed subscribers. Every line links to the full record. We never contact permit applicants — only opted-in subscribers who asked for it, under CAN-SPAM.
Coverage
Two feeds are live: the DC Department of Buildings building-permits layer published through DC open data, and the Montgomery County Department of Permitting Services feed on dataMontgomery. Additional jurisdictions are planned. We do not buy lists, scrape private databases, or contact applicants. Every record on the site links back to a source permit ID so you can verify it with the issuing jurisdiction.
Browse the feed| Source | Jurisdiction | Records · cadence |

Each record carries a data-as-of timestamp. Montgomery County refreshes at 06:00 UTC and Washington DC at 07:00 UTC. Prince George's County, Fairfax, and Arlington are on the Phase 2 roadmap and are not ingested yet.
Phase 2 · Interest list
Phase 2 is on the roadmap, but not yet scheduled. To plan it sensibly we want to hear from the firms who would actually use it. Washington DC and Montgomery County are already live on the public feed; pick the counties you want Permitline to ingest next.
This is a planning signal, not a product waitlist — everything Permitline publishes today is already free and open to browse. We'll email you a link to confirm this signup, and that is the only message it triggers: it does not enroll you in the daily digest or add you to the subscriber list. To get the digest, subscribe separately.
Get started
Browse is free with no account required. Subscribers can save searches by work type and address text, and receive a daily digest of the matches. Digest sending is paused right now, so saved searches keep collecting matches but no email goes out yet. Every email includes an unsubscribe link and a physical address, per CAN-SPAM.
After you confirm, head to Saved searches to add filters by work type, DC ward, or address text. Pause, edit, or delete any of them at any time.

Permitline republishes public open-data records from the issuing jurisdictions. Records are provided "as-of" the date stamped on each entry and are not authoritative. Always verify scope, valuation where the jurisdiction publishes one (DC publishes none), contractor information, and status with the issuing jurisdiction (DC Department of Buildings or Montgomery County Department of Permitting Services, depending on the record) before bidding, quoting, or performing work. Permitline never contacts permit applicants; all marketing flows go only to opted-in subscribers, with unsubscribe and physical address per CAN-SPAM.
