Late Rent on a San Antonio Rental: Late Fees, NSF, and the 3-Day Notice Done Right

Rent is late the moment it is not in your hand on the due date. What you can do about it, though, is tightly controlled by Texas Property Code § 92.019 and § 24.005 — and most new landlords in Bexar County either leave money on the table or hand the tenant a defense by moving too fast. The rules are not complicated, but they are specific, and the JP courts enforce them literally.

This is the playbook for the first ten days of a late-rent cycle on a San Antonio rental: when the clock starts, what you can charge, what to put in writing, and when the 3-day notice to vacate actually goes on the door.

Day 1 is not late-fee day

Under Texas Property Code § 92.019, a landlord cannot assess a late fee until rent remains unpaid two full days after the date it is due. If rent is due on the 1st, the earliest a late fee can lawfully post is the 4th. Charging on the 2nd — a common mistake copied from out-of-state lease templates — is a statutory violation that can cost you the fee plus $100, actual damages, and the tenant's attorney's fees.

A few things that trip up first-time landlords:

• The two-day window is a floor, not a grace period you have to grant. Rent is still legally late on day one; you just cannot monetize that fact yet.
• You cannot shorten the window with lease language. Any clause that says "late fee assessed on the 2nd" is unenforceable on its face.
• You can make the fee due immediately on day three. You do not have to wait longer.

What a lawful late fee actually looks like

Section 92.019 says the fee must be a "reasonable estimate of uncertain damages" that are hard to calculate — lost time, bookkeeping, follow-up. The 2019 amendments created a safe harbor: a fee is presumed reasonable if it does not exceed 12% of monthly rent on a single-family home (or a duplex, triplex, or fourplex) and 10% on larger properties.

On RentInSA's active listings, the median asking rent across the metro is $1,700/mo as of October 2026, with the City of San Antonio proper sitting at $1,650 and Cibolo closer to $2,080. Translate that to the safe harbor:

• $1,650 rent, single-family: max safe-harbor late fee around $198
• $1,700 rent, single-family: around $204
• $2,080 rent in Cibolo, single-family: around $249

You can go higher than 12%, but then you have to prove the fee is a reasonable estimate of your actual uncertain damages. In a JP court, that is a losing fight for a landlord who collects on a dozen units a month. Stay inside the safe harbor and the fee is essentially bulletproof.

You can also charge an initial fee plus a daily fee (for example, $150 flat plus $10/day), as long as the total through the month does not blow past the safe-harbor cap. Spell both numbers out in the lease. If the lease is silent on late fees, you cannot charge one — the statute requires written notice in the lease.

NSF and returned-payment fees are a separate statute

A bounced check or a reversed ACH is governed by Texas Business & Commerce Code § 3.506, not § 92.019. You can charge a processing fee of up to $30 for a returned check, in addition to the late fee, provided the lease authorizes it. Zelle reversals, failed ACH pulls from a portal like Avail or Baselane, and chargebacks on a card payment all qualify as returned payments for this purpose.

Two practical notes:

• The $30 cap is statutory. Do not write $50 into the lease and assume no one will notice; a tenant who disputes it in JP court will win that line item.
• A returned payment does not restart the two-day clock on the late fee. If rent was paid on time by check on the 1st and the check bounces on the 5th, rent was never legally paid — the late fee is calculated from the original due date.

The 3-day notice to vacate

If you decide to evict for non-payment, Texas Property Code § 24.005 requires a written notice to vacate before you can file. The default is three days, but the lease can shorten or lengthen that window — most Texas Apartment Association leases keep three days, and most landlord-drafted leases should too. Shorter is risky because a defective notice is the single most common reason evictions get kicked in Bexar County JP court.

What the notice must contain and how to deliver it:

• A clear demand that the tenant vacate (not just "pay or we will file" — the statute requires a demand to vacate; you can offer payment as an alternative, but the demand must be there).
• The date of the notice.
• Delivery by one of the methods in § 24.005: in person to the tenant, in person to anyone over 16 at the residence, by mail (regular, registered, or certified), or by securely affixing it to the inside of the main entry door. Taping it to the outside of the door is only allowed under narrow conditions and is a routine reason for dismissal.
• The three days run from the day after delivery, and weekends and holidays count.

File in the Bexar County Justice of the Peace precinct where the property sits — Bexar has four JP precincts, and venue is jurisdictional. Precinct 3 covers much of the north and northeast (Stone Oak, Converse, Live Oak); Precinct 1 covers the near west and south; Precinct 2 the near east; Precinct 4 the far south. The rental address determines the court, not your address. File through eFileTexas; the filing fee plus citation runs roughly $150–$200 depending on service. Hearings are typically set 10–21 days out.

What most people get wrong

Five patterns show up over and over in first-year landlord disputes:

• Charging the late fee on day two. The statute requires the fee to be unlawful until the end of day two. Posting it on the 2nd is a § 92.019 violation and the tenant can recover the fee plus $100, damages, and attorney's fees. Set your software to post on day three at the earliest.
• Writing a late fee higher than 12% without doing the math. If you charge 15% because another landlord told you to, you have given up the safe harbor and taken on the burden of proving actual damages. The correct move is to stay at or below the cap and layer in a modest daily fee if you want more teeth.
• Serving the notice to vacate on the outside of the door. § 24.005 allows outside posting only when the inside is inaccessible and only with mailed backup. JP judges in Bexar routinely dismiss cases where the constable's return shows outside-door posting without the statutory predicate. Deliver in person, mail certified, or affix inside the door — pick one and document it with a photo and a sworn declaration.
• Accepting partial rent after serving notice. Taking $800 of a $1,700 rent payment after you have served the notice to vacate waives the notice in most cases unless you have a written non-waiver agreement signed at the time of partial payment. Either refuse the partial payment or get the non-waiver in writing before you deposit it.
• Filing in the wrong precinct. The eviction has to be filed in the JP precinct where the property is located. Converse (78109) is Precinct 3; a property in Southtown (78204) is a different precinct entirely. Filing in the wrong court costs you the filing fee and 2–3 weeks.
• Treating a Section 8 or HAP-contract tenant like any other non-payer. HUD-funded tenancies have their own notice requirements layered on top of state law, and the housing authority (in San Antonio, Opportunity Home) must be served alongside the tenant. Skipping that step gets the case dismissed on day one.

Build the paper trail before you need it

Every late-rent cycle should generate three documents, whether or not it ends in eviction: a ledger entry showing the date rent was due, the date it was received, and the fee charged; a copy of the written notice (late-fee reminder, then notice to vacate if it goes that far); and proof of delivery. If the tenant cures on day four and pays in full, you still want the ledger. Patterns matter — a tenant who is late six months in a row and cures each time is a non-renewal conversation, not an eviction, but you cannot have that conversation without the records.
