Townline

New tenant leads from change-of-occupancy and fit-out permits

A business moving into a space files permits before it opens: a change of use or occupancy, an interior fit-out, a new sign. You get each one with the street address, the type of work, the job value and the contractor when the town records them, so you can reach the new tenant before it opens.

How it’s used

How teams that sell to new businesses use it.

01

Direct mail to new tenants

Each week, mail every change-of-occupancy and fit-out address in your area, before the business opens.

02

Sell what a new space needs

Cleaning, security, telecom, furniture, signs, waste and insurance: a fit-out permit says a space is about to be occupied.

03

Map the week's move-ins

Permits come geocoded, so reps can plan visits street by street.

04

Time the visit

Where the town reports status changes, you see when the work is approved and when it is signed off, so you can reach out as the tenant moves in.

Delivery

Pull what changed, not the whole file.

Every dataset is a feed with a cursor, delivered by API. Run it hourly, daily or weekly, and never re-download yesterday’s records.

01
Changes, not dumps — Your first pull returns the backlog. After that, each pull returns only what's new or changed since the last one: new records, status changes, and new filings on a place you already have.
02
Search when you need it — Look up permits by county, town, trade, property type, status, date or keyword, sorted by date or valuation.
03
One key for your team — JSON over HTTPS, up to 1,000 records a call, limited to the areas you license.
