Is this address in a Texas MUD or PID?
Type a Texas address to see the municipal utility districts, water control districts and public improvement districts that contain it, and which notice law applies. Free, no sign-up.
Covers 2,805 Texas water districts mapped by TCEQ and Fort Worth PIDs, as of Nov 7, 2026. Boundaries come from TCEQ and city records: they are approximate and not a survey. Tax rates and debt are self-reported by each district to the Texas Comptroller. PinSharing doesn't decide whether a notice is required for a sale; confirm with the district's own notice form (Water Code §49.453 requires districts to post it) or the appraisal district.
For title, escrow and listing software
The Texas special districts API returns every district at a point with its self-reported tax rate (with the year), outstanding debt, website, distance to the boundary and the notice statute, in one call. Answers you may keep, hard monthly caps, no overage bills.

What is a Texas MUD?
A municipal utility district is a local government that builds and runs water, sewer and drainage for a development, usually outside city limits, and pays for it with bonds repaid by a property tax on homes in the district. That tax is on top of city, county and school taxes.
What does a seller have to disclose about a MUD?
Texas Water Code §49.452 requires the seller of property in many water districts to give the buyer a written notice, before the contract is signed, with the district's tax rate and bonds; the wording is in §49.4521, and each district must post its own notice form on its website (§49.453). If the notice isn't given, the buyer may be able to end the contract. Public improvement district assessments have a separate notice under Property Code §5.014. This page is not legal advice.
How accurate is this lookup?
Boundaries come from the Texas Commission on Environmental Quality and city records; they are approximate, not a survey. In Fort Bend County about 90% of points inside the appraisal district's MUD boundaries fall inside ours. We flag points near a boundary, and a "no district found" answer is not proof that none applies: confirm with the appraisal district or the district itself.
Can I look up many addresses or use this in my software?
Yes: the API answers with every district, its tax rate, debt, website and the notice statute, for title, escrow, brokerage and listing software. It comes with the Growth plan ($49 a month) and up, with a free 14-day trial. For the whole state as a file, see the data licence.
