Most San Antonio landlords use a standard lease template and hope for the best. When a tenant stops paying, sublets the property without permission, or runs an unauthorized business from the rental, they discover that the standard template covers none of it in enough detail to act on. This guide fixes that — clause by clause, with the enforcement steps that actually work in Bexar County.
Why Standard Lease Templates Fail San Antonio Landlords
A lease is a legal instrument. Its value is not in signing it — it is in having provisions that hold up when you need to enforce them. Standard templates (from Rocket Lawyer, LawDepot, or property management franchises) are written for general use across all 50 states. They omit the Texas-specific enforcement mechanisms and the clause specificity that Bexar County courts require before they issue a judgment.
When a lease violation case goes to justice of the peace court in Bexar County — which is where most eviction cases land for amounts under $20,000 — the judge is looking for specificity. A lease that says "tenant must maintain the property" is unenforceable as written. A lease that says "tenant must change HVAC filters monthly; failure to do so resulting in HVAC failure constitutes a material breach allowing landlord to terminate with 5 days written notice" gives you something to work with.
The Five Clause Categories That Actually Matter
1. Rent Payment — Be Specific About Every Step
The most common lease violation is also the most poorly documented in standard agreements. Your lease should specify:
- Due date and grace period: "Rent is due on the 1st of each month. A grace period extends through the 3rd. Rent received after 5:00 PM on the 3rd is considered late."
- Late fee structure: Texas law allows landlords to charge reasonable late fees. Document both the flat fee ($50) and the daily fee ($15/day after the grace period) separately. Courts look for reasonableness — $50 flat is routinely upheld; $200 flat gets scrutinized.
- NSF/bounced check fees: State law caps this at the lesser of $50 or 5% of the check value. Specify it to the dollar amount allowed.
- Payment method: "All rent must be paid via [portal / ACH / check]. Cash payments will not be accepted." This matters — if you later accept a cash payment without documenting it, you may have waived the right to enforce the payment method clause.
- Pay-or-quit notice trigger: In Texas, you must give a tenant 3 days' written notice before proceeding with eviction for nonpayment. Your lease should reference this timeline explicitly: "A payment not received by the 5th day following the due date triggers a Notice to Vacate under Texas Property Code §92.109."
2. Unauthorized Occupancy and Subletting
San Antonio's housing market has created a common problem: tenants who sublet rooms on Airbnb without the landlord's knowledge, or who move in additional occupants not on the lease. This is a material lease violation — but only if your lease says so explicitly.
Your lease should state:
- "The premises may be occupied by the tenants listed on this agreement only. No additional occupants may reside in the property for more than 7 consecutive days without prior written landlord approval."
- "Subletting or short-term rental of the property without explicit written landlord consent is a material breach of this agreement and grounds for termination."
The 7-day threshold matters — it prevents casual guest stays from becoming de facto tenancy claims while remaining defensible. Texas courts have held that guests who stay beyond the period specified in a lease can establish tenant rights in certain circumstances.
3. Unauthorized Modifications and Alterations
Landlords in neighborhoods like Monte Vista, Tobin Hill, and Dignowytz Hill — where the housing stock is older and character-rich — frequently encounter tenants who paint walls without permission, install smart home devices that require structural modification, or run businesses from a residential property.
A well-drafted lease addresses all three:
- Painting: "Tenant may not paint, wallpaper, or otherwise alter the interior walls without prior written landlord approval. Unauthorized alterations may be charged against the security deposit at move-out for restoration costs."
- Structural or utility modifications: "Installation of exterior locks, smart home devices requiring wiring changes, or any modification to electrical, plumbing, or HVAC systems requires prior written landlord approval."
- Business use: "The property may not be used as a principal or secondary business address, home office for more than one employee, or any commercial activity. Home-based businesses not involving foot traffic, deliveries, or employees are permissible with prior approval."
For short-term rentals specifically: Texas law has limited local government authority to regulate STRs, but your lease can and should prohibit it. If a tenant is running an Airbnb out of your property in violation of your lease, you have grounds for eviction under the unauthorized use clause — regardless of what the city does or does not regulate.
4. Property Condition and Maintenance Responsibilities
Texas Property Code requires tenants to maintain the property in "clean and sanitary condition" and to dispose of garbage properly. Your lease should go further — explicitly assigning maintenance responsibilities so you have grounds to act when those responsibilities are not met.
Key provisions:
- HVAC filter changes: "Tenant is responsible for replacing HVAC filters at minimum every 30 days. Failure to maintain HVAC filters resulting in system damage constitutes negligence and tenant liability for repair costs."
- Lawn/landscaping: "Tenant is responsible for maintaining the lawn, landscaping, and exterior condition unless otherwise specified in a separate addendum." Specify the expectation (mowing frequency, weed control) so you can point to a breach if the yard becomes a code enforcement issue.
- Reporting obligations: "Tenant must report any maintenance issue, water leak, pest activity, or safety concern to landlord within 48 hours of discovery." This is critical — if you can show a tenant knew about a problem and did not report it, you have stronger grounds for any damage claim at move-out.
5. Noise, Nuisance, and Neighbor Disputes
Bexar County JP courts handle neighbor disputes and noise complaints regularly. Your lease should define what constitutes a violation and what evidence you will document:
- "Quiet hours are 10:00 PM to 8:00 AM. Excessive noise during quiet hours, documented by neighbors or police reports, constitutes a nuisance violation."
- "Behavior creating a nuisance for neighbors — including but not limited to repeated noise complaints, trash violations, or threatening behavior — is grounds for lease termination with 30 days' notice."
The documentation requirement is critical. Keep a written log of every complaint. Date, time, nature of the issue, and whether it was resolved. If you end up in eviction proceedings, a contemporaneous log is your evidence. A verbal complaint you remember but did not write down is worthless.
How to Enforce a Lease Violation in Bexar County
Step 1: Document Everything Before You Act
Before you send any notice, make sure you have documentation. For nonpayment: records of every payment, the date it was due, and the date it arrived. For property damage or unauthorized use: photos with timestamps. For neighbor complaints: a written log.
Your documentation strategy:
- Take photos at move-in (or your last documented inspection) as the baseline
- Conduct inspections every 6 months and document the condition
- Save all tenant communications — text messages, emails, portal messages — in a dedicated folder per tenant
- Keep police reports or code enforcement records if applicable
Step 2: Send Written Notice — Texas Law Dictates the Timeline
Texas has specific notice requirements depending on the violation type. Your lease can add to these but cannot reduce them below the statutory minimum:
- Nonpayment: 3-day notice to vacate (Texas Property Code §92.109). The notice must state the amount due and that failure to pay within 3 days results in eviction.
- Other violations (unauthorized pet, unauthorized occupant, breach of lease): 3-day notice to cure or vacate. You must give the tenant 3 days to fix the problem before you can proceed with eviction. If they fix it within 3 days, the violation is resolved.
- Nuisance or illegal activity: In some cases you can give a 3-day notice to vacate without a cure period (Tex. Prop. Code §94.052 for criminal activity or drug-related violations on the premises).
All notices must be in writing. Hand-delivery or certified mail with return receipt are the preferred methods. Posting on the door is legally acceptable in Texas but creates documentation challenges — photograph the posted notice with a timestamp if you use this method.
Step 3: File in JP Court — Bexar County Specifics
If the tenant does not comply within the notice period, file in the Bexar County Justice of the Peace court for the precinct where the property is located. Filing fee is around $45–$55 depending on the precinct.
Bexar County has four JP courts that handle landlord-tenant matters. Know which one covers your property's address before you file:
- JP Court 1: Central/south Bexar County
- JP Court 2: Northwest/north Bexar County
- JP Court 3: East/northeast Bexar County
- JP Court 4: Southwest/west Bexar County
The filing itself is straightforward — you complete a eviction petition form stating the grounds for eviction, attach a copy of your lease and your notice, and pay the filing fee. The court will schedule a hearing within 10–14 days.
Step 4: The Hearing and Beyond
Bring three copies of every document: one for the judge, one for the tenant, one for yourself. Walk the judge through the timeline: lease start, when the violation occurred, when you gave notice, and when the notice period expired without compliance.
If you win, the judge will issue a judgment for possession. You then file a Writ of Possession with the constable's office. The constable will schedule a move-out date — typically 5–7 days after the writ is issued. On that date, the constable will physically remove the tenant if they have not vacated.
Timeline from filing to actual possession: typically 3–5 weeks for an uncontested case. Longer if the tenant contests or files delays.
What Lease Violations Cost You — and How to Avoid Them
The average Bexar County eviction costs the landlord $600–$1,200 in filing fees, attorney time, lost rent, and property damage — and takes 4–6 weeks from filing to resolution. That number balloons if the tenant has belongings that require storage or if the property is damaged beyond the security deposit.
The better strategy is to prevent violations through clear lease terms, regular inspections, and early intervention when you see the warning signs:
- Payment is consistently late but arrives — add a late fee clause and enforce it from the start
- Neighbor complaints start coming in — send a written warning referencing the lease clause and document it
- Tenant requests to add an occupant — respond in writing, referencing the lease, even if you approve it
