Markets for car wash: a site research checklist
Use this markets for car wash checklist to organize vehicle-base, water, competitor, land, and traffic research before comparing potential sites.
What to take away
- Compare fifteen named markets: Frisco and McKinney, Minneapolis-St. Paul, Phoenix, Atlanta, Charlotte, Fairfax and Loudoun, Memphis, Orlando, Las Vegas, Columbus, Houston, Austin, Newport Beach and Irvine, San Antonio, and Tampa-St. Petersburg.
- Score each on four criteriavehicle base and commute flow, water and discharge authority, competitor density, and land plus traffic access.
- A 2027 opening is permitted in 2026, and car wash construction typically runs 12 to 24 months, so the rules in force now shape the site.
- Each market below names one permitting body and one number to pull. Without those two, the entry is a checklist, not a comparison.
Why 2027 shapes the shortlist
2027 is a planning horizon, not a scheduled federal rule change. Nothing in the water, sewer or stormwater rules resets on that date.

What shifts is your own clock. A tunnel or in-bay automatic typically takes 12 to 24 months from lease signature to first paid wash, a typical range rather than a fixed figure.
Access permits and utility connections sit inside that window, so a shortlist built this year governs a 2027 opening.
Owners adding a second site often carry assumptions that no longer hold. The expansion and market guide sorts what travels from an existing operation and what should be dropped.
Four criteria that decide the comparison
Keep four numbers per market. Add a fifth and the shortlist stops working as a shortlist.
Four Criteria Per Market
- Vehicle base | Census, registrations
- Water and discharge | utility, DEQ
- Competition | websites, field drive
- Land and access | brokers, DOT
- Weight vehicle base double
- Name who rechecks water rule
| Criterion | What to collect | Source to use |
|---|---|---|
| Vehicle base | Households and registered vehicles in the trade area | Census tract data, state motor vehicle registrations |
| Water and discharge | Utility rate sheet, sewer discharge limits, stormwater permit class | City water utility, state DEQ or DEP, local pretreatment program |
| Competition | Express tunnels and in-bay automatics inside the drive radius | Operator websites, a field drive at peak, local permit records |
| Land and access | Asking rent or sale price, posted speed, turn restrictions | Commercial brokers, MPO traffic counts, state DOT access permits |
Pull them in this order:
- Gather all four numbers for every market on the list.
- Score each from 1 to 5 and write the source beside the score.
- Weight vehicle base double, because the other three can be bought with capital.
- Set a review date and name who rechecks the water rule.
Water use also shifts by wash stage. The EPA WaterSense vehicle wash guidance measures conveyor, in-bay automatic and self-service systems separately.
Buyers who want the supply and discharge sequence before they commit will find it in the startup guide.
A market with no named permitting body is not a comparison entry. It is a research task.
Research leads for fifteen markets
Each row is a starting point, not a verdict. Verify the responsible body and choose a locally relevant number to pull before spending on diligence.

Permit classes vary by state. The licensing and compliance guide shows how to read an approval letter for the conditions that cap bay count.
Cold-weather and water-constrained entries need different evidence
Minneapolis-St. Paul and Columbus turn on freeze protection, salt load and winter peaks. Reclaim payback looks different there than in Phoenix or San Antonio.
Cold vs Water-Constrained Evidence

Evidence to request
- Minneapolis-St. Paul
- Columbus
- Phoenix
- Las Vegas
- San Antonio
- Austin
Phoenix, Las Vegas and San Antonio start with supply. Ask for a written allocation or a commercial rate schedule before you buy traffic counts.
Austin limits some residential washing, which pushes demand toward commercial bays. Newport Beach and Irvine turn on labor rules and hand-finish skill instead.
Queue length decides how many cars an hour the lot can feed. ASTM's design article on car wash facilities covers layout and queue flow across wash formats.
Where to pull the numbers, market by market
Use primary pages. State DEQ and DEP permit search pages publish draft and issued permits by facility. Metropolitan planning organizations publish traffic counts by segment. Water utilities publish commercial rate sheets and sewer limits.
Do not trust a directory for competitor counts. The SBA's market research and competitive analysis guide explains how to size a trade area and test demand before you commit capital.
When two markets land within a point of each other, the site selection and location guide narrows the choice to a parcel, where access and stacking decide the outcome.
