How do you pull property lead lists in Harris County, Texas?
Harris County investors can pull two free lead lists: 2025 tax-delinquent parcels from a public ArcGIS Online layer at arcgis.com, and City of Houston building code enforcement violations from data.houstontx.gov. Both are free, with owner or parcel details on every record.
How do I pull tax delinquent records step by step?
The Delinquent Parcels 2025 layer on ArcGIS Online maps Harris County parcels carrying delinquent 2025 property taxes, with owner and account details attached to every parcel.
Open the Delinquent Parcels 2025 page
Navigate to the public Delinquent Parcels 2025 map layer on ArcGIS Online. It maps Harris County parcels carrying delinquent property taxes for 2025, with the owner and account details attached to every parcel — public, no sign-in required.
Open the points layer
Under Layers, click Delinquent_Parcels_Points. That opens the layer's own page listing every field available — account number, owner name, site address, city, ZIP, and the tax year owed. (You can also click the Data tab at the top to browse the rows directly.)
Open the search form
Scroll to the bottom of the layer page and click the Query link to open a simple search form over the delinquent parcel records.
Pull the records
In the Where box type 1=1 (all records), and in Out Fields type acct_num, owner_name_1, site_str_num, site_str_name, site_str_sfx, site_city, site_zip, tax_year. To work one area at a time, use a Where like site_zip = '77026' instead. Set Format to HTML and click Query (GET) — results come back as a readable list.
Record the data
For each lead, capture the account number (the Harris County parcel/tax account ID), owner name, the site address (street number, street name, suffix), city, ZIP, and the tax year owed. Verify the current balance for any account with a free search on the Harris County Tax Office site — owners with years of unpaid taxes are prime candidates for an offer before the county forces a tax sale.
How do I pull code violations records step by step?
The City of Houston's Department of Neighborhoods publishes its code enforcement cases — dangerous buildings, nuisances, and property maintenance violations — on the city's official open data portal at data.houstontx.gov.
Go to the City of Houston Open Data Portal
Navigate to data.houstontx.gov. This is the City of Houston's official open data site.
Open the Building Code Enforcement Violations dataset
Search for City of Houston Building Code Enforcement Violations (DON) or go straight to the dataset page. These are code enforcement cases from the Department of Neighborhoods — dangerous buildings, nuisances, and property maintenance violations.
Open the violations table
Under Data and Resources, click the resource named All Code Enforcement Violations in FORMS Since 2014 to open its preview table (over 375,000 rows). Each column has a filter box under its header.
Filter by status and sort by date
Use the filter box under the Project_Status column to keep only active cases (statuses like Open or In Violation rather than Closed). Then click the RecordCreateDate column header to sort the newest cases to the top, and filter Zip if you work specific ZIP codes.
Download the data
Click the Download button on the resource page to save the file (it is provided as an Excel spreadsheet). Open it in Excel or Google Sheets and apply the same status and date filters there if you prefer.
Record the Data
For each case, capture the NPPRJID (case number), Violation_Category, Project_Status, Merged_Situs (property address) with Zip, the HCAD number (parcel ID), and RecordCreateDate (when the case opened). Plug the HCAD number into the Harris County Appraisal District site to pull the owner's name and mailing address.
