Texas Property Code 92.019 Late Fee Cap: The 12% vs 10% Rule Landlords Miss

Texas caps residential late rent fees at either 12% of rent or 10% of rent, depending on building size, under Tex. Prop. Code Section 92.019. A late fee that exceeds the statutory cap is unenforceable, and the tenant can recover the overcharge plus $100, three times the overcharge, and attorney fees. This post breaks down the rule, the grace period requirement, the "reasonable estimate" alternative, and the five mistakes landlords make in their late fee clauses.

The 12% / 10% rule at 92.019

Tex. Prop. Code 92.019(a-1), added by the 2019 legislature and still controlling in 2026, sets a safe harbor cap:

• 12% of one month's rent if the dwelling is in a structure with four or fewer dwelling units.
• 10% of one month's rent if the dwelling is in a structure with more than four dwelling units.

The cap is on the total late fee, not a per-day rate. A landlord can charge a one-time flat fee, a per-day fee, or a combination, as long as the total across the month stays under the cap.

Example 1. Fourplex, rent $1,500. Maximum late fee: $1,500 x 12% = $180 total.

Example 2. 20-unit apartment, rent $1,500. Maximum late fee: $1,500 x 10% = $150 total.

Example 3. Single family home, rent $2,500. Single family is 1 unit so it falls under "4 or fewer". Maximum late fee: $2,500 x 12% = $300 total.

The Texas late fee calculator computes the cap for any Texas rent amount and structure size.

Grace period requirement

Tex. Prop. Code 92.019(a) prohibits a landlord from charging a late fee unless:

1. The rent is at least one full day past the date on which it is due, AND
2. The lease states, in writing, that a late fee will be charged, AND
3. The rent has not been paid before the late fee is assessed.

Texas does not require a specific number of grace days beyond one full day past due. A lease can assess a late fee on the second day of the month if rent is due on the first. However, most Texas leases voluntarily include a 2 to 5 day grace period as a matter of good practice and tenant relations.

Unlike some states, Texas does not require the late fee clause to be conspicuous (bolded or underlined), only that it be in writing in the lease.

The 'reasonable estimate' alternative

Tex. Prop. Code 92.019(a-2) allows a landlord to charge a late fee above the 12% / 10% cap only if the fee is a "reasonable estimate of uncertain damages" from the late payment that would be incapable of precise calculation.

In practice, the reasonable estimate alternative is almost never used because:

1. It requires the landlord to prove (if challenged) that the actual damages are uncertain and incapable of precise calculation.
2. Most residential late-payment damages (collection effort, bookkeeping time) are low and predictable.
3. Texas courts construe this exception narrowly against landlords.

The safe harbor caps (12% / 10%) are a bright line. A landlord who stays at or below them is presumed reasonable. A landlord who goes above them has to win a fact fight at trial.

What happens if the fee exceeds the cap

Tex. Prop. Code 92.019(e) lays out the penalty for charging an excessive late fee:

• The fee is unenforceable.
• The tenant can recover the overcharge, plus
• $100, plus
• Three times the amount of the overcharge, plus
• Reasonable attorney fees.

Worked example. Duplex (2 units, so 12% cap applies), rent $1,800. Cap is $216. Landlord charges $300 late fee each month for 12 months. Tenant sues.

• Overcharge: $84/month x 12 = $1,008.
• Statutory damages: $100.
• 3x overcharge: $3,024.
• Attorney fees: say $3,500.
• Total landlord exposure: ~$7,600+.

Missing the cap by $84/month costs the landlord $7,600. The upside (collecting $84/month extra) was $1,008. The risk-adjusted math does not work.

The penalty stacks per violation. A clause in the lease that sets a fee above the cap can generate overcharges every month the tenant is late.

Common landlord mistakes

1. Using a flat dollar late fee that exceeds the percentage cap at the current rent level. A $200 flat late fee works for a $1,700 rent (12% = $204) but not a $1,500 rent (12% = $180). If rent drops mid-term or the unit turns over, the same flat fee can become illegal.

1. Charging a per-day fee with no cap language. A $10/day fee over a 30-day month is $300. On a $2,000 rent that is 15%, well above the 12% cap. The lease needs a cap clause, e.g., "late fee accrues at $10/day, capped at 12% of monthly rent."

1. Applying the 10% cap to a duplex or triplex. The 12% cap applies to buildings with 4 or fewer units. Small-building landlords regularly apply the 10% cap out of caution and lose the extra 2% they were entitled to.

1. Assuming the reasonable-estimate alternative is easy to win. It is not. Most Texas courts default to the 12% / 10% cap and require strong evidence before allowing a higher fee.

1. Charging a late fee on the first day rent is due. Texas requires rent to be at least one full day past due before a late fee can be assessed. A lease that says "late fee assessed on the due date" is invalid.

How to structure a compliant late fee clause

A compliant Texas late fee clause should:

• State the amount or percentage of the late fee.
• Identify whether it is a flat fee, per-day fee, or combination.
• Include an explicit cap at 12% (4 or fewer units) or 10% (more than 4 units) of monthly rent.
• State when the fee accrues (e.g., "if rent is not paid by the end of the day on the Xth of the month").
• Cross-reference Tex. Prop. Code 92.019.

Sample clause (fourplex, $1,500 rent):

"If Tenant fails to pay rent in full by the end of the day on the 3rd of the month, Tenant shall pay a late fee of $150. An additional fee of $10 per day shall accrue for each day rent remains unpaid thereafter, provided that the total late fee shall not exceed 12% of one month's rent ($180) as permitted by Tex. Prop. Code Section 92.019."

That clause caps total exposure at $180, stays within the safe harbor, includes a grace day (rent due on the 1st, late fee after the 3rd), and cites the statute.

Where to get a compliant lease

Every LeaseKit Texas residential lease template at leasekit.io/templates includes a 92.019-compliant late fee clause with the 12% or 10% cap auto-selected based on building size, the grace period, and the statutory reference. $29 one-time.
