Is the MUD notice required even if the seller is a builder or developer?

Yes. Water Code §49.452 applies to sellers of real property in a district regardless of whether the seller is an individual homeowner, a builder, or a developer. New-construction transactions in MUD-heavy suburbs like Katy, Cypress, and the Woodlands almost universally include the notice as a standing part of the builder's contract package. A builder who fails to include the notice faces the same statutory remedies as any other seller.

What if the buyer says they already know the property is in a MUD?

The statute does not have a "buyer already knew" exception. The notice must be delivered in the prescribed statutory form regardless of the buyer's actual knowledge. A buyer who verbally acknowledges MUD status but does not receive and sign the statutory notice retains all §49.452 rights, including the right to terminate the contract or sue for damages if the formal notice is never delivered.

Does the notice have to be updated between listing and contract?

The tax rate and standby fee figures on the notice should reflect current values at the time of contract. Districts set their tax rates annually (typically in September or October), so a listing that spans a fiscal year change may need an updated notice. A notice with materially stale figures may itself be defective under §49.452, particularly if the current rate is higher than the disclosed rate and the difference is material.

What is the standby fee, and who owes it?

A standby fee is a charge levied by some districts on undeveloped or vacant lots to fund infrastructure maintenance and debt service even when the lot is not consuming water or sewer services. Standby fees are typically not owed on developed, occupied residential lots — but the notice must disclose the standby fee amount because the buyer may hold the property in undeveloped status at some point, and the fee could become owed under those circumstances.

Can the buyer waive the notice requirement?

The statute does not authorize waiver. Even if the buyer signs a contract with a purported waiver of §49.452 rights, the statute's protective provisions likely control and the buyer can still assert notice-based remedies. Buyers who understand and accept district taxes should still receive and sign the notice — it is the delivery of the statutory disclosure, not the buyer's separate knowledge, that discharges the seller's duty.

How do I check whether a property is in a MUD?

The county appraisal district (CAD) maintains tax records showing all taxing entities that apply to a specific property, including MUDs, WCIDs, and other special districts. Searching the property address on the CAD website typically returns a taxing jurisdictions list. The Texas Commission on Environmental Quality also maintains a public registry of active water districts searchable by name and location. Title commitments often flag district taxes as well, though the title company's disclosure is not a substitute for the statutory notice.

Texas MUD District Notice: Water Code §49.452 Explained

TL;DR

Texas Water Code §49.452 requires the seller of real property located in a Municipal Utility District (MUD) or other statutorily defined district to give the buyer a statutory Notice to Purchaser before executing a binding contract of sale. The notice discloses the district's name, tax rate, standby fee, bonded indebtedness, and other district-specific charges. Under §49.452(f), the rule works in three tiers: notice delivered before contract execution fully protects the seller; notice not delivered before execution entitles the purchaser to terminate the contract; but if the seller cures late (before closing) and the buyer nonetheless elects to close, all termination and damages rights are conclusively waived. TREC's Notice to Purchaser of Special Taxing or Assessment District (TREC Form 59-0, adopted 2024 under 22 TAC §537.66) is a voluntary form that satisfies §49.452 and §49.4521, but §49.453 requires each district to make its own notice publicly available; the seller should use the district's own form if available, and use TREC 59-0 only as a fallback.

What a MUD is and why the notice exists

A Municipal Utility District is a political subdivision of Texas created under Chapter 54 of the Water Code (with parallel authority for other district types under Chapters 49, 51, and elsewhere) to finance and provide water, sewer, drainage, and related infrastructure in areas outside existing city services. MUDs are common in the master-planned suburbs of Houston, Dallas-Fort Worth, and Austin because they let developers front-fund infrastructure through district bonds that the district then repays through property taxes and standby fees levied on residents within the district's boundaries.

From a buyer's perspective, purchasing property inside a MUD means taking on district taxes and fees on top of city, county, and school taxes — often adding fifty cents or more per $100 of assessed value to the overall property tax burden, and sometimes substantially more in newer districts still paying off construction bonds. The statutory Notice to Purchaser exists so buyers understand this obligation before they are contractually bound. Historic underdisclosure of district taxes in early suburban development motivated the notice statute's original enactment.

What the §49.452 notice must contain

Water Code §49.452 sets out the specific content of the Notice to Purchaser. The statute prescribes the exact wording of the disclosure, which the seller must complete with current district figures. A complete notice includes the following core elements:

Notice Element	What Must Be Disclosed
District name	Full legal name of the MUD, water control and improvement district, or other conservation and reclamation district
Tax rate	Current district property tax rate expressed in dollars per $100 of assessed value
Standby fee	Any standby fee levied by the district (typically applied to undeveloped or vacant lots)
Bonded indebtedness	The principal amount of any bonds approved or issued by the district and payable from taxes on the property
Other district charges	Any other district-imposed charges the buyer will owe as an owner within the district
Signed acknowledgment	Buyer's signed acknowledgment of receipt of the notice

The statutory language must be reproduced substantially as prescribed by §49.452 — sellers cannot paraphrase or summarize the notice into their own words without risk. Filling in the district-specific values (tax rate, standby fee, bond amount) with current figures at the time of contract is the seller's responsibility, and stale figures can themselves create disclosure defects.

Delivery timing and the pre-binding-contract rule

The critical delivery rule is that the notice must be given to the buyer before the sale contract becomes binding. In a TREC transaction, this means before the buyer signs the One to Four Family Residential Contract (Resale) — TREC 20-18 in current usage — or, at latest, contemporaneously with the buyer's signature and initialed acknowledgment on the MUD addendum incorporated into the contract package.

Notice delivered before the contract binds fully protects the seller from statutory remedies. If notice is delivered late — after the contract has bound — the buyer gains a statutory right to terminate the contract without liability and to receive a refund of earnest money. If notice is not delivered at all, the buyer may sue for actual damages, may seek rescission, and may be entitled to attorney's fees under §49.4645. The statute is one-sided in favor of the buyer, reflecting the legislature's judgment that MUD disclosure is material information that should not surface for the first time at closing.

TREC Form 59-0 and district-provided notices in practice

For transactions using TREC promulgated forms, the delivery mechanism is either the district's own statutorily prescribed notice or, if the district does not publish its own, the TREC Notice to Purchaser of Special Taxing or Assessment District (TREC Form 59-0). TREC 59-0 was adopted in 2024 under 22 TAC §537.66 following HB 2815 and HB 2816 (88th Legislature), which consolidated the various district disclosure notices into a single statutory framework. The form is voluntary — TREC's own guidance is that if the district has its notice available (usually on the district's website under Water Code §49.453), the seller should use the district's form; TREC 59-0 is the fallback when the district's own form is not available.

Note that TREC Form 47-1 is unrelated to MUD/§49.452 notices, and TREC Form 53-0 (Addendum Containing Notice of Obligation to Pay Improvement District Assessment) is for Public Improvement District (PID) assessments under Local Government Code Chapter 372, which are governed by a separate disclosure regime. Do not confuse the PID addendum with the §49.452 water district notice.

Listing agents in known MUD areas should treat the notice as a standing requirement of the listing package, not an afterthought at contract signing. Verifying district status through the county appraisal district's records or the Texas Commission on Environmental Quality's list of active water districts is a due diligence step every listing agent should perform for property in unincorporated or newer suburban areas. For related seller-disclosure obligations that must be delivered concurrently, see our Texas Seller's Disclosure Notice guide.

Districts covered by §49.452 and districts covered elsewhere

Under §49.452(a), the term "district" is defined narrowly for §49.452 purposes: (1) a district governed by Local Government Code Chapter 375, or (2) a district created under the Water Code or by a special legislative act that provides — as its principal function — water, sanitary sewer, drainage, or flood control facilities or services, financed by bonds payable from district taxes or by standby fees. MUDs are the archetypal §49.452 district, and Water Control and Improvement Districts (WCIDs) and Fresh Water Supply Districts also typically fall within the definition. Not every "special district" or municipal utility structure is a §49.452 district — the statute's specific definition controls.

Public Improvement Districts under Local Government Code Chapter 372 are NOT §49.452 districts; they have a separate PID disclosure regime, and TREC Form 53-0 (Addendum Containing Notice of Obligation to Pay Improvement District Assessment) is the vehicle for PID disclosures — distinct from the MUD notice under §49.452. The practical effect for licensees is that district status must be checked precisely: is this a Chapter 375 or Water Code district (§49.452 applies) or a Chapter 372 PID (separate PID disclosure applies)? The county appraisal district, TCEQ registry, and district counsel can help resolve close cases before contract execution.

Failure-to-disclose remedies and licensee exposure

Water Code §49.452 provides a graduated remedy structure. Under §49.452(f), a buyer who does not receive the required notice before contract execution has a statutory right to terminate the contract. If the seller cures late by delivering the notice before closing and the buyer nonetheless elects to close, the buyer is conclusively presumed to have waived all termination and damages rights. If the sale closes without any compliance, the buyer's damages remedies are provided in §49.452(o) (reconveyance of property to seller upon payment of damages) and §49.452(p) (alternative suit for damages not to exceed $5,000, plus reasonable attorney's fees). Under §49.452(q), remedies under (o) and (p) are mutually exclusive and are the exclusive statutory remedies. Section §49.452(r) requires suit within 90 days after the buyer receives the first district tax notice or within four years after the sale, whichever is earlier.

Licensee exposure runs alongside seller exposure. A listing agent who knows or should know the property is in a district but fails to secure the required notice may face TREC disciplinary action under Rule 535.156 (fraudulent or dishonest dealing) and civil claims under general agency and negligence principles. Note that §49.452 also contains a limited safe harbor: sellers, brokers, title companies, and examining attorneys are not liable if the district failed to file the required information form and map under §49.455, or if the wrong statutory notice was unintentionally provided. Buyer's agents who fail to verify district status and advise their client can face liability under general agency and negligence principles.

Bottom Line

Texas Water Code §49.452 requires sellers of real property inside a MUD or other statutorily defined district (Local Government Code Chapter 375 district or Water Code / special-act district providing water/sewer/drainage/flood-control services financed by bonds or standby fees) to deliver a statutory Notice to Purchaser before the sale contract becomes binding. The notice must disclose the district's name, current tax rate, standby fee, bonded indebtedness, and other district-specific charges. Under §49.452(f), a buyer denied timely notice can terminate; if the seller cures late but the buyer closes anyway, all rights are conclusively waived. If the sale closes without compliance, §49.452(o) and (p) provide mutually exclusive damages remedies (with (p) capped at $5,000 plus reasonable attorney's fees), and §49.452(r) sets a suit deadline. TREC Form 59-0 (Notice to Purchaser of Special Taxing or Assessment District, adopted 2024) is a voluntary fallback form when the district does not publish its own notice under §49.453 — the district's own form should be used first when available. Do not confuse TREC 59-0 with TREC 53-0 (PID assessment addendum for Local Government Code Chapter 372 PIDs, a separate regime).
