From a Parking Space to a Football Field: Texas's New Drive-Thru Setback

In McKinney, Texas, the drive-thru speaker problem had a number: 20 feet. That was the old minimum, about the width of a single parking space, between a drive-thru speaker box and a single-family residential zone. On May 6, 2025, the city council voted 5-1, with Council Member Charlie Philips absent, to set the new number at 200 feet, two-thirds of a football field. Fifteen drive-thrus in McKinney became out-of-compliance overnight, though the city allowed them to keep operating as-is.

Council Member Geré Feltus summarized the policy logic in a single sentence: "I'd much rather lean into protecting the residents at this point and then having these folks come in and just apply for the variances." Council Member Michael Jones, the sole dissent, framed the same vote the other way: "I feel like we're creating problems that don't really exist now for the future." Rodney McDaniel lives in the historic Wilcox neighborhood and sat with a fast-food speaker backed up to his neighbor's property. He gave CBS Texas the framing that drove the staff work: "Through time, they've torn a lot of these houses down and then they sat on it until the time was right."

The vote is being read locally as a noise ordinance. It is something larger. Setbacks between drive-thrus and single-family neighborhoods are the new growth-management tool in Texas's exurbs, and the thing those setbacks measure to is not the building. It is the menu-board speaker.

How 20 Feet Became 200

The amendment passed as Legistar File 25-0001M, modifying Sections 205 and 206 of Chapter 150 of the McKinney Unified Development Code. The new rule sets a 200-foot minimum between any drive-thru and a single-family residential use or zone, measured to both the building and the speaker box. The minimum drops to 150 feet when a public street separates the two uses. Anything tighter than that requires a specific use permit (SUP) the city can grant or deny case by case.

The April 22 Planning and Zoning Commission recommended it 7-0. City Planner Cameron Christie told that hearing the rule was about distance, not use: "The goals for this amendment are to introduce those distance requirements for drive-thru restaurants."

Interim Planning Director Hayley Angel made the city's grandfathering assurance on the council record: "In general terms they are allowed to continue their use. It's not our intent to retroactively change those for those properties." Existing drive-thrus keep operating. They lose that protected status if they sit empty for a year, and they cannot expand without going back to the city.

The rule started routing real applications inside four months. On September 16, 2025, the McKinney City Council approved a special permit for a Smalls Sliders drive-thru at West Grove. The speaker box sat 100 feet from the nearest residentially-zoned land, half the new threshold. Staff recommended approval because the nearest actual single-family home was 260 feet away and the residentially-zoned land in between was "likely to remain undeveloped." That gap between the zoning line and the houses themselves is the working seam in McKinney's rule. It is where the case-by-case permits now live.

Prosper Got There First

McKinney did not write this rule. Prosper did.

Sixteen months earlier, the Town of Prosper adopted Case No. ZONE-23-0033 on January 9, 2024, amending Chapter 4, Section 9 of the town's zoning ordinance. The current code language on ecode360 reads: "All buildings, structures, and outdoor speakers used in conjunction with any drive-through restaurant or drive-in restaurant shall be located a minimum of 200 feet from any residential zoning district or areas shown as residential on the future land use plan." The exemption, "an existing or future major thoroughfare," is the same exemption McKinney later wrote in as the 150-foot street reduction.

The number is the same. The exemption is the same. The phrase "outdoor speakers" is explicit. Prosper is the prototype; McKinney is the scale-up. When the second Dallas–Fort Worth (DFW) exurb adopts a rule, the question for a site-selection team is not whether the third will follow. It is which one.

That question has a useful negative finding behind it. A 2023–2026 zoning amendment search across Frisco, Allen, and Celina surfaced no drive-thru-to-residential setback rule in any of the three. Frisco regulates drive-thru escape lanes and internal sight lines. Allen and Celina rely on standard setback tables. Three DFW peer cities, none of them carrying the Prosper-McKinney rule. The gap between adopters and non-adopters is where the monitoring work lives.

The Moratorium Got Expensive

The reason permanent setback rules now do the work moratoria used to do is statutory. HB 2559 passed the 89th Texas Legislature in spring 2025 and took effect September 1. The bill rewrites the part of state law cities use when they want to pause new development in a category, say, drive-thrus or car washes, while they work out a permanent rule. It leaves permanent zoning changes alone. It only touches the temporary pauses, and it makes them procedurally expensive in five specific ways.

Newspaper notice and certified mail to requesters are due 30 days before the first public hearing, up from four days. Two hearings are required, with the second no sooner than 30 days after the first, about a 60-day timeline from first notice to second hearing. Ordinance readings have to be spaced at least 28 days apart. Final reading requires affirmative votes from three-fourths of the governing body. The pause expires 90 days after adoption unless extended, caps at 180 days total, and cannot be reimposed on the same property type in the same area for two years.

A city that wants a temporary pause under HB 2559 is signing up for two months of hearings, a supermajority vote, a three-month duration, and a two-year cooling-off bar. A permanent setback amendment is two readings, a simple majority, no sunset, and full latitude to amend again. The Texas Municipal League's August 29 guidance walked cities through the procedural lift. Cities did the math.

Mission in Real Time

The Rio Grande Valley provided the cleanest demonstration of the substitution five weeks before HB 2559 was a year old.

Mission, Texas passed a six-month car wash pause unanimously on March 24, 2026, a single agenda item, single hearing, simple majority. HB 2559 required two hearings 30 days apart and a three-fourths supermajority. The defect was on the face of the record. Property owner and mayoral candidate Ricardo Salinas filed federal suit on April 17, 2026.

On April 29, Mission's council unanimously repealed the pause and, the same day, amended its permanent spacing ordinance, Ordinance 5761, adopted January 15, 2026, to double the required separation between car washes from one mile to two.

Planning Director Xavier Cervantes had framed the underlying policy concern in January: "All the cities are struggling to get water from the irrigation districts so we're concerned." Salinas told reporters after the repeal he was "pleased with the outcome" and still planned to develop the property, "just not as a car wash." A city spokesperson closed the file: "The lawsuit was rescinded. Therefore we will not be commenting since there is no more lawsuit."

The temporary pause failed under HB 2559. The permanent ordinance got stronger as a substitute. Different use category, same regulatory pivot, documentary record dated five weeks apart.

The Exurbs Named the Speaker

The exurbs are the ones who wrote the speaker into the rule. Prosper writes "outdoor speakers." McKinney writes "speaker box(es)." Both name the one piece of equipment that generates the late-night nuisance and build the setback around it.

Austin got to residential adjacency first, through a more comprehensive instrument. Austin's compatibility code, Section 25-2-1063, imposes a 25-foot buffer — a 10-foot screening zone plus a 15-foot restricted zone — that limits what can be built and operated close to single-family homes. The buffer kicks in when a large site sits within 75 feet of an SF-5-or-more-restrictive lot. Austin's reform, Ordinance 20240516-004, effective July 15, 2024, cut that trigger distance from 540 feet to 75 feet.

That buffer restricts what operates near homes. It does not single out the menu-board speaker. The Texas exurbs went more granular than the big city. They did not catch up to Austin; they passed it on specificity, isolating the speaker and writing the rule around the object that actually carries the sound.

The corporate site-selection rubric still reads building-footprint setback off a zoning table. That table is now reading the wrong row. Under the McKinney rule, the speaker, not the building, sets the 200-foot line. The Prosper code language puts the speaker on the same line as the building. The convergence is structural.

The geometry has practical consequences. The measured distance is to the residential zoning district, not the nearest house. The Smalls Sliders staff report quietly used both numbers: the speaker was 100 feet from residentially-zoned land but 260 feet from the closest actual home, which is how the special permit cleared. The measurement also runs to that zoning line, not to the drive-thru pad's own property line, so a pad's internal setbacks are not the controlling number.

And the speaker has its own geometry. It can sit closer to the residential zone than the building does, and frequently does on tight pads with looping queues. A standard prototype that meets a 200-foot building setback can still fail on speaker distance.

Outside Texas, the Same Result Without the Rule

The same geometry shows up in jurisdictions that never amended a setback line. The instrument changes; the regulated object does not.

In Tucker, Georgia, the Planning Commission recommended approval on April 16, 2026 for a Whataburger at 4453 Hugh Howell Road, a former Wendy's that closed mid-2025. One of the recommended conditions was that the drive-thru speaker be relocated away from residential. Tucker did not write the McKinney rule. It wrote the McKinney result onto a single application as a permit condition. The site plan submitted by the franchisee already shows the relocated speaker.

In Siloam Springs, Arkansas, the staff report for a Whataburger at 2960 Highway 412 recommended approval of the use and development permits in February 2022, on the express condition that the applicant separately obtain a variance for the drive-thru speaker box. The building got one approval; the speaker got its own. That is the cleanest documentation in the record of the speaker as a separable, individually-regulated element.

In Sandy Springs, Georgia, the city council voted 3-3 on August 19, 2025, with Mayor Rusty Paul casting the tie-breaker to deny a conditional use permit (CUP) for a Whataburger at 8721 Roswell Road. Huntington Place townhomes sat directly south. Huntington Place homeowner Adrianne Murchison gave the council the line that summarized the geometry the McKinney rule is engineered to prevent without a hearing: the drive-thru would expose her townhomes to "speaker system, customer voices, cars idling, headlights shining towards our windows." Councilmember Melody Kelley called the use incompatible with ongoing North End revitalization, per Appen Media.

A permit condition in Tucker, a standalone speaker variance in Siloam Springs, a permit denial in Sandy Springs. The instrument changes site to site; the controlling element does not. The pattern crosses state lines.

What to Watch

The leading indicator for the next adoption is not the city where the drive-thru chain owns dirt. It is the peer-adjacent city whose Planning Commission has not yet amended its code.

For the DFW corridor, that means Frisco, Allen, and Celina. Each has the same residential-adjacency pressure as McKinney and the same growth-corridor pad inventory. A monitoring rubric scoped to them flags adoption before underwriting is done.

Outside Texas, the instrument shifts toward case-by-case permitting. Tucker's 2025 Special Land Use Permit (SLUP) regime converted drive-thrus from automatically allowed to case-by-case on a corridor where the previous Wendy's authorization lapsed after six months of vacancy. Sandy Springs uses its existing conditional-use process. Siloam Springs uses standalone speaker variances. The pattern to monitor is not "did the city pass a 200-foot rule." It is "did the city move drive-thrus from automatically allowed to case-by-case, on any instrument, in any code chapter."

For developers and land-use counsel

The McKinney rule contains three measurement traps that prototype underwriting tends to miss. The first is the reference object: the 200-foot dimension runs from speaker to the residential zoning district boundary, not to the nearest dwelling unit and not to the property line of the drive-thru pad.

The second is the seam between zoning distance and lot distance. Smalls Sliders at West Grove cleared its SUP at 100 feet of speaker-to-zone separation because the staff report could document 260 feet of speaker-to-dwelling separation. The finding rested on intervening residentially-zoned land that was "likely to remain undeveloped." Not every pad will support that finding.

The third is queue geometry. A prototype that meets a 200-foot building setback can still fail on speaker distance. The speaker frequently sits closer to the residential boundary than the building itself, particularly on tight pads with looping or reverse-flow queues.

The SUP pathway is the safety valve for anything tighter than the new minimum, including the 150-foot right-of-way (ROW)-separated dimension. The application turns on the same staff findings that cleared Smalls Sliders: measured distances to zoning and to nearest dwelling, the status of intervening parcels, the FLUP designation, and the queue geometry on the proposed site plan.

The discretionary nature of the SUP means timeline doubles relative to a by-right pad and the entitlement risk shifts from a checklist to a hearing record. The fifteen drive-thrus that became legal nonconforming on May 6, 2025 keep their use under Director Angel's recorded assurance. They lose that status after twelve months of cessation and cannot expand without coming back through the SUP process.

The monitoring rubric across the Sun Belt is by-right versus discretionary, not 200-foot rule versus no rule. The instruments diverge. Prosper and McKinney used permanent setback amendments. Tucker used a 2025 SLUP regime that converted drive-thrus from by-right to discretionary corridor-wide. Sandy Springs used the existing CUP process to deny. Siloam Springs required a standalone variance for the speaker as a separable use element.

The Sun Belt taxonomy runs from CUP condition through SLUP designation through standalone speaker variance to permanent setback amendment. Every one of those instruments moves the drive-thru pad off the by-right column. Sites that read as by-right on a broker aerial may already be sitting under a discretionary instrument in an adjacent code chapter. The monitoring rubric reads the entitlement column, not the setback table.

The Speaker, Not the Building

For years the site-selection question was how close the building could sit to the property line. McKinney changed it to how close the speaker can sit, and in sixteen months it moved the answer from the width of a parking space to two-thirds of a football field.

Austin's compatibility buffer has restricted what operates near homes for years. The exurbs went further and named the speaker itself. The number that controls a drive-thru pad is no longer building-to-lot-line. It is speaker-to-zoning-line. And the exurb that hasn't passed the rule yet is the one to watch, because the one next door already has.
