Austin Build + Connect (AB+C) has a public permit search that does not require registration, but confirm that the property was inside the City of Austin for the period you are researching. Start with the City’s jurisdiction verification instructions, then use AB+C Public Search. Keep each permit or case number you find; Austin’s manual warns that a related-folder list may not show every case at the same address.
Reviewed October 15, 2026 against the City of Austin’s AB+C page, current online manual, and addressing-verification page. Those sources describe the available inputs and visible record sections. This guide does not assume buttons, defaults, or result fields beyond what the City currently documents.
Check jurisdiction and annexation before opening AB+C
An Austin postal address is not enough to establish that the City issued a permit. The City’s jurisdiction map instructions say the Property Profile can show the parcel ID, jurisdiction, county, buildings and units, and annexation history. That information matters when a property lies near city limits, has units with separate identifiers, or entered the City after construction.
- Choose “Find my Jurisdiction” in the City map described on the addressing-verification page.
- Select the offered address match and open Property Profile.
- Record the jurisdiction, county, parcel ID, and any building, unit, or Place ID/RSN that identifies the correct property.
- Review annexation history when the work may predate the property’s entry into Austin.
- If another government had jurisdiction at the relevant time, search that custodian instead of expecting AB+C to supply the full history.
Choose the AB+C tab that matches the identifier in hand
Austin’s AB+C Manual documents two public-search methods. The first accepts a permit number, Folder RSN, ROW ID, or case number. The second searches by property, project name, types, and date range. Registration is not required for either public-search route.
| You have | Use | Why |
|---|---|---|
| Permit or case number | Identifier tab | It reopens one known record without relying on address matching |
| Folder RSN | Identifier tab | It identifies a permit or case folder; it is not the property’s Place ID |
| Only an address | Property search | Check the linked address against the City-recognized property |
| Project name or work period | Project/type/date search | It can narrow a large result set when the address has many cases |
Use the Property search for the verified address and check the linked property in each result. If a highway address does not match, compare it with the City’s documented examples and abbreviations before narrowing the date range. Avoid assuming an unsupported wildcard format.
Open the detail page and follow the project outward
The manual identifies separate permit-detail areas for general information, permit-specific information, linked property, associated people, fees, process notes, and public attachments. For a history check, concentrate on the property, work description, permit type and number, dates, status, process notes, inspections, and publicly shareable documents.
- Confirm that the linked address and building or unit details match the property being reviewed. Keep its Place ID separate from the permit’s FolderRSN.
- Separate a plan-review number from the resulting building or trade permit number.
- Read “Processes and Notes” for review steps and unresolved comments that a summary status may not explain.
- Open public attachments only when they belong to the same permit or plan-review record.
- Review associated building, electrical, mechanical, plumbing, demolition, right-of-way, or other records when the project generated separate filings.
Do not treat Related Folder as a complete address history
Austin’s manual says related folders are applications and permits directly related to one another, commonly a building permit and associated trade permits. It also says not all cases at the same location, or even with the same address, will be displayed. That makes the related list a project clue, not a substitute for a fresh property search.
After following the related records, return to the property search and test the address across the relevant work period and permit types. Keep unrelated projects separate. A remodel, demolition, solar installation, accessory structure, and right-of-way case may share an address without belonging to one permit chain.
Translate Austin status evidence cautiously
An active permit is not a final approval, and a closed permit should still be read with its final inspection and process history. The AB+C manual specifically directs users to Public Search for closed permits after a final inspection. Even then, the record describes the City’s workflow for the listed scope; it does not confirm that the present building matches every approved plan or that no other work occurred.
- An application or plan review is not an issued construction permit.
- An issued permit does not prove that the work was performed or passed inspection.
- A passed inspection applies to the listed inspection event, not automatically to every trade.
- A closed record does not fill gaps from before annexation or records kept by another jurisdiction.
- A public attachment is evidence for the record it belongs to, not a certification of current site conditions.
Application-to-issue gaps are not City review times
Keep the application and issue dates separate when building an address history. Austin’s Issued Construction Permits dataset defines the application date as potentially coming from the original plan-review submission. Subtracting it from the issue date measures a recorded calendar-day gap, not time spent actively reviewing a building permit.
Our October 13, 2026 check of 323 residential addition-and-remodel building permits issued from July 1 through September 30, 2026 found a 60-day median gap, with the middle half between 33.5 and 114 days. That is in line with the 75-day median for the same work class in 2023–2024 shown in the analysis below. The data can’t say whether a long gap was spent in City review, waiting on the applicant, or idle.
Two building permits can share one parent plan-review ID. BP records 2026-089043 and 2026-089044, for example, have separate Project IDs (13735767 and 13735768) but the same plan-review ID (13718238), and both were issued 31 days after application. Search each BP separately, then compare their shared parent record, and use the permit-status guide to keep issuance, inspections, and closeout separate.
What 23,171 recent Austin building permits show about expired repairs
We downloaded every Austin building permit (permit type BP) issued in 2023 and 2024 from the city’s open data set (Austin Open Data, Issued Construction Permits, pulled October 23, 2026) and checked what status each one shows now. That is 23,171 permits; 22,760 remain after removing withdrawn, void, and cancelled records. Trade permits (electrical, plumbing, mechanical) are counted separately in the city’s data and are not included. The numbers below are our own calculation from the city’s records, not figures published by the Development Services Department.
| Permit (city class and work class) | Permits issued 2023–24 | Days from application to issue (median) | Slowest 10% took at least | Now “Expired” |
|---|---|---|---|---|
| Residential repair | 4,860 | 2 | 91 days | 21% |
| Residential addition and remodel | 2,709 | 75 | 343 days | 11% |
| Residential new | 5,948 | 74 | 439 days | 8% |
| Residential demolition | 1,220 | 36 | 367 days | 15% |
| Commercial remodel | 5,436 | 63 | 373 days | 16% |
| All building permits | 23,171 | 54 | 406 days | 15% |
Three things stand out for anyone checking an Austin house before buying.
- Quick repair permits are the ones that end up Expired. Residential repair permits were typically issued within two days, yet 21% of them (993 of 4,747) now show “Expired” instead of “Final.” For repair permits issued in 2023, the share is 24%. Additions and remodels, which typically took weeks to issue, expired about half as often (11%).
- Foundation and window work dominate the repair list. Of the residential repair permits, 2,217 describe window replacement and 1,162 describe foundation repair. About one in five foundation repairs (243, or 21%) and 17% of window jobs ended as Expired. On a house with a recorded foundation repair, ask for the final inspection for that permit.
- Austin’s status field does move to Expired. Fewer than 1% of the 2023–24 residential repair permits still show “Active.” That differs from Los Angeles, where old permits often keep saying “Issued” (see our Los Angeles permit analysis). In Austin, an Expired label on a past repair is a common, readable signal that no final was recorded, and that is the record to ask the seller about.
Limits of this count: the data set lists issued permits only, so applications still in review are not counted, and the application date may come from the original plan-review submission, as the section above explains. Valuation fields are often blank for repair permits, so we did not break results down by project cost. Work descriptions are free text, so the foundation and window counts are keyword matches. Statuses are the city’s current status field as published on the pull date.

Austin trade permits and certificates of occupancy in 2024
Building permits are only part of an Austin address history. Electrical (EP), mechanical (MP) and plumbing (PP) work each get a separate permit, often under the same project, so one remodel can leave four records at the address. Of the 7,064 residential building permits Austin issued in 2024, 82.7% reached Final by October 2026 and 12.1% had expired. Repair permits expired most often, at 17.4%.
- Electrical (EP): 12,049 residential permits issued in 2024, 91.4% Final, 7.3% expired.
- Plumbing (PP): 12,373 issued, 89.6% Final, 9.3% expired.
- Mechanical (MP): 7,481 issued, 80.2% Final, 18.7% expired.
Mechanical permits cover HVAC work, and their 18.7% expiration rate was the highest of any residential permit type in 2024. If a house has a newer AC unit or furnace and its MP reads Expired, that work never recorded a final inspection. The seller or the HVAC contractor can ask DSD to reactivate it with the city’s extension, withdrawal and reactivation form.
Certificates of occupancy issued after August 9, 2019 appear in AB+C Public Search, and 93% of the 2024 new-home building permits are flagged in the data as requiring one. Older COs are requested through the city’s certificate of occupancy request form. Complaint cases at an address are searched separately in Citizen Connect.
These 2024 counts are our calculation from the same Issued Construction Permits data, pulled October 24, 2026: residential permits issued January 1 to December 31, 2024, excluding withdrawn and void records.
When the address produces no useful permit
Return to Property Profile and verify the selected address, unit, RSN, jurisdiction, county, and annexation date. Then search a known permit, case, or plan-review number. Broaden the work period only through the documented date search, and check whether the project might be filed under a different permit type or a separate trade record. If the address has a Work Without Permit complaint, our analysis of 1,017 Austin work-without-permit complaints shows how those cases usually end and how often a permit followed.
If the property was outside Austin when the work occurred, contact the government that had permitting authority then. If City jurisdiction is correct but the record generation is unclear, give Austin 3-1-1 or the responsible department the address, RSN or parcel ID, approximate work date, project description, and any identifier already found. Ask for the correct public-record route rather than asking staff to endorse a no-result conclusion.
Build one Austin timeline from the returned folders
Use a simple chronology: jurisdiction and annexation evidence; City-recognized address and RSN; application or plan review; issued permits; related trade permits; inspections; corrections; final or closed event; public attachments; checked date. The permit-status guide can help keep process terms separate, while the address-not-found guide provides a broader recovery checklist.
End the review with two lists: what the City record demonstrates for the matched project, and what it cannot answer because of jurisdiction, annexation, record linkage, or missing documents. That split is more useful than compressing several AB+C folders into one “permitted” or “not permitted” label.
If a permit shows an open 611 or 610 inspection, that’s an Austin Water item; our Austin Water tap and meter records guide explains how UPO closes it.
