Houston's rental AC rule takes effect December 17. Enforcement is a 311 call to a department already taking 800 complaints a year

Houston City Council voted 12-2 on August 19 to require working air conditioning in every rental unit in the city. The rule takes effect December 17, and the only way the city learns a landlord is ignoring it is if the tenant calls 311.

Why it matters

For decades a Houston landlord could satisfy the building standards code by putting screens on the windows instead of installing refrigerated air. That is now over. But the council wrote the rule and left the machinery of enforcing it undefined, so what the rule is worth to a renter in August depends on how the health department is staffed in July.

By the numbers

12-2, the council vote on August 19, 2026. Council Member Alejandra Salinas sponsored it. Sallie Alcorn, Mario Castillo and Edward Pollard co-sponsored.
120 days, the compliance window in the ordinance. That puts the effective date at December 17, 2026, which is what KPRC reported and what the calendar confirms.
20,400 rental units with no air conditioning, per 2023 Census figures. That count covers the Houston metro area. The ordinance covers the city.
700 to 800 no-air-conditioning complaints the Houston health department already takes in a typical year, by its own count.
7,600 heat related illness cases reported in Harris County between 2019 and 2023.
279 heat deaths recorded statewide in Texas in 2022.

What the coverage buried

The 20,000 figure is doing more work than it can carry. It is a metro area count, and Governing noted plainly that there are fewer such units inside the city proper. Every outlet we read labeled it a Houston area or metro number, so nobody got it wrong. But none said the ordinance stops at the city line, so the most quoted number in the coverage overstates how many units the law reaches. No outlet published the city only count.

Second, nobody put the effective date next to the season. A cooling mandate whose deadline falls on December 17 will be complied with, or not, in the coldest six weeks of the Houston year. The first honest test of this ordinance is June 2027.

Third, no outlet reported a fine amount or an inspector count. Both are knowable and both decide whether this works.

The other side

Two council members voted no, and their objection is the serious one. Twila Carter called it “an unfunded mandate with no meaningful guardrails for the tenants,” and argued that a renter who cannot make rent cannot absorb a higher electric bill either. Fred Flickinger said some renters would end up without housing. A landlord told KPRC he would raise the rent at his first opportunity. That is not posturing. The cost lands somewhere, and here it lands on a low income renter twice, in the rent and in the utility bill.

Two things answer it partly. The ordinance accepts window and portable units, so no landlord is forced into a central air retrofit, which caps the capital cost. And the Houston Apartment Association, the landlord trade group, backed the ordinance rather than fighting it. What does not answer it: nobody priced either side. Not compliance, not utilities, not 7,600 heat illness cases. The council voted without those numbers.

What to watch

December 17, 2026. The compliance deadline.
Whether the city publishes a fine schedule and an inspector count before that date. Neither has been reported.
The health department’s complaint volume in the first quarter after the deadline, measured against its current 700 to 800 a year.
Summer 2027. The first stretch of 100 degree days the rule has to survive.

Bottom line

Requiring refrigerated air in a city that runs 100 degrees is not a hard call, and the landlord association agreeing says most of what needs saying about how burdensome it is. The open question is not the rule. It is that Houston passed a complaint driven mandate onto a department already fielding 800 of those complaints a year, published no fine, named no inspector count, and set the deadline for December.
