The 45-Day Clock: Texas's Manufactured-Housing Law Isn't a Rezoning Mandate, It's a Deadline
Nacogdoches satisfied Texas's new manufactured-housing law on August 4, 2026, with three unanimous council votes in one night: a comprehensive-plan update, a new zoning district, and the rezoning of exactly one subdivision into it.
The subdivision is Millard's Apple Park on Wen Road: roughly 30 acres, 69 lots, moved out of R-3 and into a newly created R-3M district where HUD-code manufactured homes are allowed by right. The rest of the city's zoning map stayed where it was. Nacogdoches had ended by-right manufactured-home permissions around 2004, which left owners in existing manufactured-home subdivisions nonconforming and unable to replace, upgrade, or expand a unit.
"Theoretically, there could be no other property owners requesting a change to R-3M beyond tonight," Mike Neu, the city's Executive Director of Development and Infrastructure, told the council. He wasn't apologizing for it. He was describing the floor the law sets, and that floor is the entire public story of Senate Bill 785 so far.
Every outlet covering the law has asked the same question: which Texas cities still have to change their zoning map, and how many are there. It's a fair question with a real answer, and it's half the statute. The other half is a deadline.
A qualifying application to install a new HUD-code manufactured home is considered granted unless the municipality denies it in writing, with stated reasons, by the 45th day after receipt. Nothing in the law requires a city to log that date, calendar it, or flag it before it expires.
Cities that measure compliance in the smallest defensible unit on the zoning map will measure it the same way at the intake desk. That's what makes the undocketed clock the more dangerous obligation.
Compliance at the floor
SB 785 amended Tex. Occ. Code § 1201.008 and took effect September 1, 2026. It lands in the same run of Texas preemption statutes as ETJ release under SB 2038 and the multifamily by-right mandate in SB 840.
A municipality has to designate at least one zoning classification where a new HUD-code manufactured home is allowed by right, for dwelling use. That's the whole mapping obligation. Subdivisions, planned developments, individual lots, or rental communities all qualify as places a city can point to, and the statute sets no minimum acreage, no minimum lot count, and no market-viability test.
Nacogdoches read that accurately. Months of staff work produced three unanimous votes in a single night, including a new district and the rezoning of one existing subdivision into it. The nonconforming-status problem Neu described is fixed for those 69 lots, and owners there can now replace or upgrade a home. For everyone else in Nacogdoches, the zoning map reads the same on September 2 as it did on August 3.
Two cities, one statute, opposite answers
Pearland didn't have to do anything. Its MH district predates SB 785, spreads across seven areas totaling 51.32 acres, and allows manufactured homes by right with no conditional-use approval, which on the text of the statute is compliant. It also carries a three-acre minimum lot size, which works out to about seventeen buildable lots citywide, best case, in a market where most buyers are shopping for something smaller. Pearland reported zero applications and zero inquiries under the district as of September 9, 2026.
DJ Pendleton, Executive Director of the Texas Manufactured Housing Association, has a name for the large-lot pattern: "creative compliance." He's blunter about what the statute actually accomplished. "The direct answer that I give is, it just means that cities can't ban manufactured housing entirely." That's the state's own trade association, describing its own legislative win at its real size.
League City ran the opposite play. Instead of carving out a large-lot district few buyers could use, its planning department opened its smallest-lot, highest-density single-family classification: a text amendment to the Unified Development Code allowed manufactured homes by right in RSF-2 and stripped the remaining specific-use-permit requirement. The April 23, 2026 staff report reasoned that RSF-2's existing character, small lots at high density, made it the consistent fit. The amendment took effect ahead of the September 1, 2026 deadline.
Striking the SUP requirement wasn't generosity, and it wasn't the only compliant move. Section 1201.008(d-1)(2) bars a municipality from requiring a specific-use permit for a new HUD-code manufactured home unless it requires the same permit for other residential uses in the same zoning classification. That cuts both ways: League City could have added the SUP requirement to every home in RSF-2 and satisfied the same clause. It leveled down instead, cleaning up its table rather than defending a carve-out.
Same statute, same deadline, two cities that arrived at answers with almost nothing in common. Both are compliant.
The obligation nobody has mapped
Mapping compliance and permitting-process compliance are two separate obligations under the same statute. Nacogdoches, Pearland, and League City each cleared the first one. Nothing any of them did speaks to the second.
Section 1201.008(b) reads: "An application to install a new HUD-code manufactured home for use as a dwelling is considered to be granted unless the municipality in writing denies the application and states the reason for the denial not later than the 45th day after the date the application is received." That language is from the enrolled bill text.
A denial has to be in writing, state its reasons, and go out inside 45 days of receipt. Miss any one of the three and the application is granted by operation of law: a denial issued on day 47 is a denial of something already approved on day 45, and a timely denial that doesn't state its reasons is not a denial the statute recognizes. A phone call telling the applicant it won't work is a phone call.
The clock runs from the date the application is received, not the date it's routed or the date it's deemed complete. Received. Texas land-use law does this regularly elsewhere too: Chapter 245 vested rights works on the same principle, freezing the rules that govern a project as of the filing date of the first application in a series.
The statute imposes no tracking duty. It doesn't require a municipality to acknowledge receipt, log the date, calendar day 45, or tell anyone the window is closing. The deadline is enforceable against the city without the city ever having been told, in code, to watch it.
An ordinary file in an ordinary queue
Consider a hypothetical, offered as illustration. A homeowner's application gets stamped received on an ordinary Tuesday and routed to plan review with everything else that came in that week, because no code provision tells the permit system this one is different. Comments come back, the applicant revises and resubmits, and nothing in § 1201.008's text stops or restarts the count along the way. Whether an incomplete or under-review application would actually toll the clock is a question no city has tested yet, but as written, the statute runs from receipt.
Day 45 arrives. If no written denial with stated reasons has left the building, the application is granted, whether it's still sitting in the queue or not. There's no letter, no hearing, no vote, no docket entry, just a permit technician who never heard of SB 785 processing a file at normal speed while the city loses its ability to say no.
No Texas city has been publicly caught by this yet. The law is weeks old, and every search of trade press, local news, and association alerts turns up explainers of the provision and no named application. That's a fact about how young the statute is. The exposure was the same size on day one.
The older way around a state mandate
Houston has no zoning ordinance. SB 785's mandate is written to attach to zoning classifications, and a city with no classifications has nothing for it to attach to, so the state's largest city sits, for practical purposes, outside the mandate's mechanism. That's a point about how the statute is drafted. Nobody in Houston is refusing anything.
The bigger carve-out applies statewide, and it's narrower than it looks. Section 1201.008(h)(2) says deed restrictions established before January 2, 2025 aren't touched by subsection (g), the mapping mandate. That's the half of the statute Nacogdoches, Pearland, and League City all satisfied. It says nothing about subsection (b), the deemed-approval clock, which means a pre-2025 covenant may keep a city out of the mapping fight entirely while leaving the 45-day clock running on any application filed anyway. The statute's own "two obligations" problem shows up again here, one layer down.
In Houston, where private covenants do the work zoning does elsewhere, a parcel can sit inside a fully compliant by-right district and still be off-limits, because a decades-old covenant says single-family site-built only, and a zoning check won't surface that. It's a title-level question, and it doesn't stay private the way it would in most Texas cities: Houston's Legal Department runs a Deed Restriction Enforcement Team under Chapter 212 of the Local Government Code and Houston Code §§10-551 through 10-555, which investigates complaints and sues for injunctions on the city's own authority. A developer who skips the title work in Houston isn't just risking a neighbor's lawsuit. The city can bring one.
How many cities are actually exposed
The number in nearly every headline is roughly 400 of Texas's 1,200-plus municipalities, about a third, attributed to the Texas Manufactured Housing Association. TMHA's own SB 785 Resource Center doesn't publish that figure or a methodology behind it. It reads as an estimate the association gave reporters, repeated as a hard count ever since.
The rigorous number is smaller in absolute terms and larger as a rate. The National Zoning Atlas reviewed 579 Texas municipalities and more than 6,700 zoning districts, covering 79 percent of the state's population, and found that 44 percent, or 255 municipalities, would need to act to comply. The dataset is dated May 2025, a pre-passage impact analysis published before the statute was on the books, and NZA didn't extrapolate its sample to the full municipal universe. Run the math anyway: 44 percent of the 1,228 Texas municipalities NZA counts as subject to the bill is above 500, a bigger problem than the round number everyone is quoting.
Most of those 255 can get there cheaply: sixty-five need only drop a hearing requirement, a Table of Permitted Uses edit like League City's, and another 70 already have an unmapped district they just need to put on the map. Cheap fixes get made cheaply. A city that satisfies the mandate by deleting a row in a use table hasn't built a 45-day tracking rule into its permit software along the way.
What to do about the clock
A Texas building department with a qualifying district needs one procedural fix: date-received capture at intake, a flag on the file, a calendared alert before day 45. Nothing in the statute requires it and no state agency checks for it, so the only thing standing between a city and an approval it never made is whether someone built that rule.
Deemed approval is real. A developer relying on one is relying on a filing date and an expired clock, and that's worth spelling out plainly before a lender or a title company asks what actually authorizes the installation. Two questions settle it, and neither shows up on a zoning map: what the district permits at its real dimensional limits, the way Pearland's seventeen viable lots hide inside fifty-one mapped acres, and whether a pre-2025 deed restriction forecloses the use regardless, which is a question for the title work.
SB 785 answers where manufactured housing is allowed. It has never answered what happens to a specific application once it's filed. That question now runs on its own clock, counting down whether or not anyone in the building department is watching it.
