Chattanooga building permit search: the LDO web portal, ChattaData and records

Where to look for Chattanooga permits

The LDO permits work inside the City of Chattanooga. Unincorporated Hamilton County, East Ridge, Red Bank, Signal Mountain and the other towns run their own permit offices.

The LDO counter is at the Development Resource Center, 1250 Market Street, Suite 1000, open Monday to Friday 8am to 4pm, the City says.

How to look up the permits on a Chattanooga address

1. Open the LDO web portal and search for the street address or the permit number on your paperwork (residential electrical numbers look like E-24-1891). The City's page does not list the portal's search fields.
2. Or download All Permits and filter its address column to the street; the file also has the status and contractor company columns.
3. Expect several permits per job. A new house gets separate building, electrical, plumbing, mechanical and gas permits.
4. Check each permit's status (table below) and, where named, that the contractor matches the one on your contract.
5. If you cannot find it, call the LDO building or trade permit line above with the address.

What the statuses mean

The City's All Permits file has three status values:

There is no expired status, so a lapsed permit still reads Active. The file's completion date is empty, so we time a permit to the date its status last changed to Complete. Of the residential permits issued October 2024 to September 2025, 50.0% were Complete and 50.0% still open by our 18 October 2026 snapshot.

When the record is not online

The City takes Tennessee open records requests through the Chattanooga Open Records Center, linked from its Open Records page, where you can browse existing records or submit and track a request. The page cites Tenn. Code Ann. § 10-7-503: "any citizen of Tennessee has the right to personally inspect a public record" (read 24 October 2026). Name the address and the years you need.

What our Chattanooga pages add

Our Chattanooga page counts residential permits the City issued, October 2024 to September 2026:

ZIP 37421 had the most permits in the window, 2,864 (21%), then 37405 with 1,628; see Chattanooga permits by ZIP code. The permit statistics page has year and month counts, how long permits take has the time to Complete by kind of work, and browse permits lists the rows. To check a licence behind a firm name, see How to check a contractor's license in Tennessee.

What this does not tell you

We count residential permits only, and we have not matched contractor names to state licence records, so the firm list is a count of permits filed, not a rating. The file carries no job value, so we show no costs.
