Selling a home in Texas: the MUD notice and flood disclosure rules
Two disclosures catch Houston-area sellers out more than anything else, and both are statutory rather than optional. Get the MUD notice wrong and your buyer can walk on closing day. Get the flood questions wrong and you have a problem that outlives the sale. Here is what the law actually says, in plain English.
This is general information, not legal advice. Disclosure obligations turn on the specific property and your own knowledge. For a question about your situation, talk to a Texas real-estate attorney — and I am happy to point you to one.
The MUD notice — Water Code §49.452
If your home sits inside a municipal utility district, Texas law does not treat the disclosure as a courtesy. Texas Water Code sections 49.452 and 49.4521 require a person selling real property located in a district to give the purchaser a written notice.
Three things about it are commonly misunderstood:
- The timing is strict. The notice must be delivered before the purchase contract is executed, or included as an addendum at the time of execution. It is not a closing-table document.
- Both parties sign. The seller signs because they are providing it; the buyer signs to acknowledge receipt.
- It carries specific numbers. The notice must state the district's tax rate, the current debt owed on its bonds, and a standby fee if one applies. The correct form comes from the statutory district itself, because those figures are district-specific.
The consequence, stated plainly. If the seller fails to deliver the required notice on time, the buyer may terminate the contract at any time up to and including the day of closing. That is the most expensive disclosure mistake available to a Houston-area seller, because it can unwind a deal after you have already committed to your next purchase.
Why the MUD rate on the notice matters to your sale
The tax rate is not just a compliance box. Buyers increasingly compare the all-in monthly payment rather than list price, and the MUD is the single biggest variable in a Houston-area payment — district rates run from roughly $0.25 to $1.40 per $100 of value. On a $450,000 home that is a swing of about $430 a month between the cheapest and priciest districts.
If your district is on the low end, that is a selling point most sellers never make. If it is on the high end, you want to know before pricing, not after two weeks of soft showings. You can model it on our True Monthly Cost calculator.
Flood disclosure — Property Code §5.008 after Harvey
Texas strengthened the Seller's Disclosure Notice after Hurricane Harvey. The revised form became mandatory for contracts executed on or after 1 September 2019, and it asks sellers to disclose:
- Whether the property is in a FEMA-designated 100-year or 500-year floodplain.
- Whether it has flooded at least once in the past five years.
- Whether it sits in a flood pool for a reservoir.
- Whether it has ever been repaired for flood damage.
- Whether the seller has ever received flood insurance proceeds.
- Awareness of previous flooding from a reservoir failure or breach, or a controlled or emergency release.
- Previous water penetration into a structure from a natural flood event.
The reservoir questions are not boilerplate in Houston. Controlled releases are part of how this region manages major storms, and they are precisely the sort of event a seller may remember differently from the public record.
What "to the best of your knowledge" actually means
The notice is completed to the best of the seller's belief and knowledge as of the date it is signed. Texas law does not require you to conduct independent research before answering.
But it does prohibit willful ignorance. Deliberately avoiding knowledge you would otherwise have is not a defence. In practice the safe posture is simple: answer honestly, disclose what you know, and where you are genuinely unsure, say so rather than guessing in whichever direction is convenient.
A practical pre-listing checklist
- Identify the exact district your address sits in — the numbered MUD or levee district, not the community name.
- Get the district's current notice, with its adopted tax rate, bond debt and any standby fee.
- Have the notice ready before you go under contract, not at the closing table.
- Complete the Seller's Disclosure carefully, including every flood question, honestly and from your own knowledge.
- Gather documentation for anything you disclose — repair invoices, insurance records, elevation certificate if you have one.
- Price with the MUD rate in view, since buyers are comparing monthly payments, not list prices.
Not sure which district your home is in?
Most sellers aren't — and it is the first thing that has to be right. Send me the address and I will identify the exact district, its current adopted tax rate and bond position, and what has closed nearby, so you go to market with the disclosure in hand and the pricing set correctly. Free, no obligation, and no requirement to list with me.
Frequently asked questions
Do I have to give a MUD notice when selling a house in Texas?
Yes, if the property sits inside a municipal utility district. Water Code sections 49.452 and 49.4521 require written notice to the purchaser, delivered before the contract is executed or included as an addendum at execution, signed and dated by both seller and buyer.
What information must the Texas MUD notice contain?
The district's tax rate, the current debt owed on its bonds, and a standby fee if one applies. The form comes from the statutory district itself, because those figures are district-specific.
What happens if a Texas seller fails to deliver the MUD notice?
The buyer may terminate the contract at any time up to and including the day of closing.
What flood information must Texas sellers disclose?
Whether the property is in a FEMA 100-year or 500-year floodplain, has flooded in the past five years, sits in a reservoir flood pool, has been repaired for flood damage, or has received flood insurance proceeds — plus awareness of flooding from a reservoir failure or a controlled or emergency release. Mandatory for contracts executed on or after 1 September 2019.
Does a Texas seller have to research flood history before disclosing?
No. The notice is completed to the best of the seller's belief and knowledge, and independent research is not required. Willful ignorance is prohibited, however.
Do I need to disclose the MUD tax rate when selling in Katy, Cypress or Sugar Land?
Yes, if the home is in a district — and most newer master-planned communities in Katy, Cypress, Fulshear, Richmond and parts of Sugar Land are. Because rates are set district by district rather than community-wide, the figure must come from the specific district serving that address.
