Your lease is the skeleton; your addendums are all the useful organs that make it actually live in the real world.
With the 2025 Legislature dropping a bunch of changes that kick fully into gear in late 2025 and 2026, Texas landlords should be thinking less “one long lease” and more “clean main lease + smart addendums.” It keeps you flexible, keeps your paperwork readable, and makes updates way easier next time Austin gets busy.
Usual disclaimer: this is general info, not legal advice. Have a Texas attorney or your association (TAA, etc.) bless your final forms.
1. Floodplain & Flood History Addendum (No, You Really Can’t Skip This)
Texas already required written notice if a dwelling is in a 100-year floodplain or has flooded in the last five years (Property Code §92.0135). The Legislature doubled down with SB 2349, effective September 1, 2025, clarifying notice requirements and carving out limited exceptions for short-term/temporary leases.
TREC’s Landlord’s Floodplain and Flood Notice (Form 54-0) exists specifically as an addendum to satisfy that requirement.
What to do in 2026:
- Use a stand-alone flood addendum for almost every standard residential lease.
- Make sure it clearly states:
- Whether you are aware the property is / is not in a 100-year floodplain.
- Whether you are aware it has / has not flooded in the last five years.
- Only skip it if you truly fall into one of the narrow temporary/short-term exemptions created by SB 2349.
This one is non-negotiable. It protects your tenant from surprise risk, and it protects you from, “You never told me this place floods.”
2. Email & Text Communication Addendum
Two things changed at once:
- HB 2037 (effective Sept. 1, 2025) explicitly allows certain landlord–tenant notices (like security-deposit notices) to be sent by email when that’s an established communication channel.
- SB 140 (effective Sept. 1, 2025) massively expands Texas’ “telephone solicitation” law to cover texts and similar electronic messages, and ties violations to the Texas Deceptive Trade Practices Act with a private right of action.
Translation: you want written clarity about how you and your tenants use email and text.
Your addendum should:
- Designate one official email address per tenant and one for the landlord/manager for notices allowed by law to be emailed.
- Get express written consent for operational texts (maintenance scheduling, emergency alerts, “rent posted” reminders) and explain that marketing texts are limited or separate.
- Explain how a tenant can revoke text consent.
This both takes advantage of the convenience HB 2037 gives you and respects the much sharper teeth SB 140 gives unhappy recipients.
3. Repairs, Access & Licensed Contractors Addendum
HB 2037 also tightens the rules around repairs made after a tenant sends a formal “intent to repair” notice. For qualifying issues, the law now expects repairs to be done by an independent contractor, and if the city requires a license for that trade, that contractor must be licensed.
A short addendum can:
- Spell out how repair requests must be submitted (portal, email, mailing address).
- Clarify that serious habitability repairs may be handled by licensed independent contractors selected by the landlord.
- Lay out reasonable entry rules (notice periods, emergency access) so you’re not arguing about access every time a vendor shows up.
You’re basically turning “we take repairs seriously and follow the statute” into a written, easy-to-point-to commitment.
4. Unauthorized Occupants & Guest Policy Addendum
New laws SB 38 and SB 1333 are all about who is legally entitled to be in a property and how fast you can remove people who aren’t. SB 1333 (effective Sept. 1, 2025) gives law enforcement a fast path to remove true squatters based on a sworn complaint and proof of ownership; SB 38 (effective Jan. 1, 2026) streamlines court-based evictions and clarifies that justice courts focus on right of possession, not title fights.
Those tools work better when your paperwork clearly shows who is and isn’t a tenant.
Good addendum topics:
- All tenants by name, plus any approved occupants (kids, partner, etc.).
- A clear rule that no one else acquires any right of occupancy without your written consent.
- Limits and timeframes for guests (e.g., more than X days = needs written approval).
- A prohibition on subletting or “re-renting” rooms via platforms or side deals without permission.
If you ever do need help from a constable or a judge, this addendum helps you show who belongs there and who doesn’t.
5. Early Termination for Safety / Crime-Related Situations
Texas has long allowed certain survivors of family violence or sexual assault to terminate a lease early if they meet documentation and notice rules in the Property Code. Recent guidance around HB 47 (effective Sept. 1, 2025) focuses on strengthening and clarifying protections for survivors of sexual assault and related offenses across the system, including how advocates help them exercise lease-termination rights.
To avoid missteps, many landlords now use a short “Victim-Rights / Early Termination” addendum that:
- References applicable Texas Property Code protections without restating them badly.
- Explains, in plain language, that tenants who qualify may have a right to terminate early, and that management will follow the law when a properly documented request is made.
- Tells staff not to argue the law with someone making this kind of request—just to escalate it to the right person.
Handled well, this reduces your risk, keeps you on the right side of the law, and treats people in crisis like human beings instead of problems.
6. House-Rules Addendums That Still Matter
Not new to 2026, but still smart as separate addendums:
- Pet addendum (types, limits, fees/deposits, damage rules)
- Smoking/vaping policy (inside, outside, balconies, common areas)
- Parking/garage addendum (assigned spaces, towing policy, guest parking)
- Mold / moisture / bedbug addenda (who does what, how to report, access for treatment)
These keep your main lease from turning into a phone book and make mid-stream updates less painful.
Final Thought
Think of 2026 as the year you stop treating your lease as one giant sacred document and start treating it as a modular toolkit: solid core lease + targeted addendums that track flood disclosures, communications, repairs, occupants, and safety rights under current Texas law.
Get the structure right once, have a Texas lawyer bless it, and the next time the Legislature gets creative, you’ll only be tweaking a page or two instead of rewriting your world from scratch.
