Texas County Appraisal Records - Owner, Address & Value Search

Every Texas county has an appraisal district that values all taxable property and publishes its certified roll as a free public bulk download. This actor turns those rolls into a charged-per-record lookup and screening tool for the four largest counties - Harris (Houston), Dallas, Tarrant (Fort Worth) and Travis (Austin) - selected with the county input.

Each record carries the owner name and mailing address, the situs (property) address, the land / improvement / total / assessed values, the year built, the legal description, the neighborhood code, the class code and the exemptions - wherever that county publishes it.

Built for: real-estate due diligence, title and ownership research, absentee-owner and farm-and-ranch identification, exemption and homestead screening, comparable-value analysis, and county-wide value/ownership analytics.

What it covers

4,353,771 parcels across four counties (free public data; each refreshed by the county):

County	District	Parcels
Harris (Houston)	HCAD	1,628,377
Dallas	DCAD	827,412
Tarrant (Fort Worth)	TAD	1,404,658
Travis (Austin)	TCAD	493,324

Fields are the union across counties - every request returns the same schema, with a field left empty where a county does not publish it:

Field	Harris	Dallas	Tarrant	Travis
Owner name + mailing address	yes	yes	yes	yes
Situs address / city / ZIP	yes	yes	yes (address/city ~55%, ZIP ~48% in source)	yes (city often blank in source)
Land / improvement / total value	yes	yes	yes	yes
Assessed value	yes	-	yes	yes
Year built	yes	yes	yes	yes
Legal description	yes	yes	yes	yes
Neighborhood code	yes	yes	yes	yes
School district	yes	yes	-	-
Exemptions	-	yes	yes	yes

Typical questions

• "Who owns this parcel, and at what mailing address?"
• "Show every parcel on Lamar Blvd in Austin valued over $10 million."
• "Find homestead-exempt homes built after 2015 in Dallas."
• "Which owners hold property in Fort Worth?"
• "How are Harris County parcels distributed by city, class and value?"

Inputs

Input	What it does
county	which appraisal roll - harris / dallas / tarrant / travis (default harris)
accountNumber	exact account / parcel number (leading zeros ignored) -> that parcel
ownerName	owner name substring, case-insensitive
city / zipCode	situs location
propertyType	coarse class label (Residential, Commercial, Vacant Land, Mineral, ) or the raw class code
schoolDistrict	school district substring (Harris and Dallas)
stateClass	the county's raw class code, exact (A1, F1, C1, RES, COM, R )
yearBuiltFrom / yearBuiltTo	build-year window (only returns parcels that record a year)
valueMin / valueMax	total-value range
hasExemption	only parcels with (or without) a recorded exemption
aggregate / groupBy	one summary row per group - city / ZIP / property type / year built
maxResults	cap records (default 200). The aggregate mode returns every group in full and is not cut by this cap.

Default run = a tiny aggregate (property-type mix for Harris) - fast and safe for the daily auto-test, never a surprise full dump.

Example inputs

Look up one parcel (Harris) -

{ "county": "harris", "accountNumber": "0010020000001" }

Owners named Leonard in Dallas -

{ "county": "dallas", "ownerName": "LEONARD", "maxResults": 10 }

Fort Worth parcels valued at $500,000 or more -

{ "county": "tarrant", "city": "FORT WORTH", "valueMin": 500000, "maxResults": 10 }

The property-type mix (Tarrant) -

{ "county": "tarrant", "aggregate": true, "groupBy": "propertyType", "maxResults": 10 }

Low cost

From $0.00005 per record, down to $0.00003 at Gold - billed only for the rows you use, and each record is metered individually.

None of these rolls has a query server behind it: HCAD is a 212 MB zip, DCAD a 198 MB zip of 18 cross-referenced CSVs, TAD a 748 MB zip whose main table is a 13.9 GB fixed-width file, TCAD a 557 MB zip of the same fixed-width family. There is no way to ask a county for "just the Lamar Blvd parcels over $10M". Rather than make every lookup pay for a multi-gigabyte download, each roll is mirrored and normalized once, and a run streams only its county's shard through the filter in a single pass. Every mirror is integrity-checked (parcel-count floor, key-column coverage, class vocabulary), so a degraded or restructured source fails loudly instead of returning bad rows.

county=tarrant, aggregate=true, groupBy=situsCity (top):

(blank)         627,610
FORT WORTH      337,332
ARLINGTON       122,880

The blank group is real: Tarrant's mineral and personal-property accounts carry no situs city.
