Dallas Building Permit Leads: 1,500 Permits a Week from Dallas Open Data (Solar, Roofing, Plumbing, New Homes)

The City of Dallas publishes every issued building permit on dallasopendata.com (Socrata dataset e7gq-4sah). Between Oct 21 and Oct 28, 2026 it issued 1,499 permits:

Each permit includes the work description (for example "Installation of roof mounted PV solar panels / 22 modules / 9.020 kW"), street address, ZIP code, square footage and issue date.

One gotcha: text dates

Dallas stores issued_date as text in MM/DD/YY format, so a normal SoQL date range (issued_date > '2026-10-21') silently returns the wrong rows. Query the exact date strings instead:

import datetime as dt, requests days = [(dt.date(2026,10,28)-dt.timedelta(d)).strftime("%m/%d/%y") for d in range(8)] where = "issued_date in(" + ",".join(f"'{d}'" for d in days) + ")" rows = requests.get("https://www.dallasopendata.com/resource/e7gq-4sah.json", params={"$where": where, "$limit": 5000}).json() print(len(rows), rows[0]["permit_type"], rows[0]["work_description"][:80]) 

For longer windows, split the request into chunks of about 31 dates.

Finding solar, roofing and HVAC jobs

Filter on the work description:

import re solar = [r for r in rows if re.search(r"\b(PV|solar)\b", r.get("work_description",""), re.I)] roof = [r for r in rows if re.search(r"re-?roof|shingle", r.get("work_description",""), re.I)] 

Note: Dallas leaves the contractor and valuation fields blank on most recent permits. Use this feed for the address, work type and timing (for example, homeowners who just pulled a re-roof or new-construction permit), not to look up a contractor.
