01 — MethodologyHow to read these numbersCar wash construction has unusually good public cost data for a niche asset class, because the biggest operators franchise: franchise disclosure documents are public filings, and their Item 7 tables itemize real build costs. This guide’s spine is the Tommy’s Express 2025 FDD, which puts total investment at $5,205,184-6,786,542 for a 90-ft tunnel, $4,976,759-7,930,608 for a 110-ft, and $5,096,490-8,522,378 for a 130-ft, with the construction line alone at roughly $2.06-3.93M depending on tunnel length.Around the FDD spine we layer industry-side numbers: International Carwash Association (ICA) market data on the roughly 62,750 US wash and detail outlets and 600-700 annual new builds, trade cost breakdowns from Professional Carwashing & Detailing / Carwash.com and car wash construction specialists (EB3 Construction, Car Wash Advisory), and an MMCG feasibility-study teardown of a $10.47M high-end project. These sources are estimates and single projects, not statistical medians, so we quote ranges and name who says what.All figures are 2025-2026 US dollars. Where a source separates hard cost from equipment and land we keep the split, because a “car wash cost” headline mixes three different markets: commercial construction (see our commercial cost per sqft guide for context), specialized wash equipment, and retail-corner land.What these figures are — and are notThese are market benchmarks compiled from public franchise filings, trade association data, and named industry estimates. They are not iRecruit placement data, not a feasibility study, and not financing or investment advice; single-project examples are labeled as such and ranges are shown wherever sources disagree.02 — At a glanceThe benchmarks at a glanceThe whole guide in one screen. Each row jumps to the full section.01Express tunnel, ground-up, all-inRoughly $3.85M to over $10M (MMCG); Tommy’s Express FDD range $5.0-8.5M including land and fees$5-8.5M02Tunnel building + sitework onlyAbout $750K-1.5M for the shell per EB3; one documented $4M project ran ~$2M at $800+/SF with sitework$0.75-2M03Express equipment packageConveyor, arches, dryers, vacuums: $1.4-2.1M typical; $1.0-2.0M for complex tunnels$1.4-2.1M04In-bay automatic$500K-1.2M all-in including site and construction; touchless equipment can hit $400-450K$0.5-1.2M05Self-serve, per bayEquipment $15-30K per bay plus construction $20-70K per bay; basic sites from ~$150K total$35-100KAnchor numbers for 2026: a franchise-grade express tunnel budgets $5.0-8.5M all-in (Tommy’s Express FDD), the equipment package alone runs $1.4-2.1M, and the same customer can be served by a $500K-1.2M in-bay automatic or a self-serve bay costing well under $100K — format choice is the entire cost story.
03 — Benchmarks2026 build-cost benchmarks by formatEach card below isolates one budget line or format, source named. The low ends generally reflect secondary markets, shorter tunnels, and independent builds; the high ends reflect prime corners, 130-ft flagship tunnels, and franchise brand standards.$5.0-8.5MExpress tunnel, all-inTommy’s Express 2025 FDD Item 7: $5.21-6.79M (90-ft), $4.98-7.93M (110-ft), $5.10-8.52M (130-ft) including land, construction, equipment, and fees. MMCG’s feasibility work frames the industry-wide spread at $3.85M to over $10M; Car Wash Advisory and EB3 put typical complete projects at $2.6-7M.$750K-1.5MBuilding shell onlyEB3 Construction’s benchmark for the express tunnel building itself. A documented $4M project with an 80-ft conveyor and 2,400 SF building ran about $2M of construction including sitework — over $800/SF — and MMCG’s $10.47M example carried $3.2M of hard cost, about $740/SF on a 4,307 SF facility.$1.4-2.1MEquipment packageThe conveyor, wash arches, dryers, water systems, and vacuum stations for an express tunnel, per 2025 trade estimates, with complex tunnel systems quoted at $1.0-2.0M. MMCG’s high-end example itemized $1.65M of equipment including 29 vacuum stations, roughly 16% of that project’s total.$500K-1.2MIn-bay automaticAll-in range for the rollover format that dominates fuel and c-store sites, per 2025 trade estimates spanning site prep, construction, and equipment. Touchless in-bay equipment alone can reach $400-450K, which is why ICA counts about 29,000 in-bay automatics — the largest US format by unit count.$35-100K/baySelf-serve, per baySelf-serve wand bays run $15-30K per bay in equipment plus roughly $20-70K per bay in construction, per trade estimates, with basic multi-bay sites starting around $150K total. ICA counts about 16,250 US self-serve locations, mostly in secondary and rural markets.$1M-4.2M+Land + sitework realityExpress washes need roughly 1-1.5 acres of high-traffic corner with stacking for 20+ cars. MMCG’s example paid $4.2M for land ($3.1M/acre) — 40% of the entire project — while secondary-market sites run well under $1M; sitework, stacking lanes, and utility connections sit inside the hard-cost lines above.Sources: Tommy’s Express Car Wash FDD (2025, Item 7), via Franchise Chatter and public FDD archives; International Carwash Association industry data; MMCG Invest tunnel car wash feasibility breakdown (2025); EB3 Construction car wash tunnel cost analysis; Car Wash Advisory; Professional Carwashing & Detailing / Carwash.com. All retrieved September 2026.Why all-in numbers scatterThe same 3,500 SF tunnel building can anchor a $3M project or an $8M one, because two of the three big lines are not construction at all. Land swings from under $500K in a secondary market to $4.2M on a prime Sunbelt corner (MMCG), and the equipment package swings roughly $700K between a value spec and a flagship one. Comparing projects without splitting land, hard cost, and equipment is how car wash budgets go wrong; FDD Item 7 tables are useful precisely because they force the split. 04 — Cost driversWhat moves the numberSix drivers explain most of the spread between a $3M express build and an $8.5M one. Ranked roughly by budget impact:+$1.9MTunnel lengthTommy’s Express FDD construction lines run $2.52-2.73M at 90 ft but $2.06-3.93M at 130 ft, and the 130-ft total tops out $1.74M higher than the 90-ft. Longer tunnels buy throughput (cars per hour), so length is a revenue decision that shows up as a construction line.~$700KEquipment brand and specThe gap between the bottom and top of the $1.4-2.1M express package: conveyor type, arch count, dryer horsepower, and vacuum count. MMCG’s flagship example ran $1.65M with 29 vacuums; touchless and premium branded systems price at the top.$50-100KWater reclaim systemsReclaim equipment runs roughly $50,000-100,000 per trade estimates, and is increasingly mandatory: many municipalities condition permits on reclaiming a share of wash water. It also cuts the sewer and water bills that dominate operating cost, so most new express builds now include it.1-1.5 acSite, civil, and stacking lanesExpress formats need enough paved stacking for peak-hour queues plus 15-30 vacuum stalls, which drives lot size, paving, and stormwater scope. Sitework helped push one documented 2,400 SF building to about $2M of construction (EB3); tight urban sites trade land cost for civil complexity.5-6 figsUtility and impact feesHigh-volume washes need large water and sewer taps, and connection and impact fees vary from a few thousand dollars to six figures by jurisdiction — a line MMCG’s feasibility framework flags inside its $750K soft-cost bucket alongside design and permitting. Verify tap fees before closing on land, not after.+$50K+Franchise vs independentTommy’s Express charges a $50,000 initial franchise fee ($40,000 for subsequent units), and brand standards on building design and equipment push franchise builds toward the top of the ranges. Independents save the fee and spec freedom but give up the proven prototype that lenders underwrite fastest.The pattern worth noticing: most drivers are locked at site selection and prototype choice, not during construction. Tunnel length, land, stacking geometry, and reclaim requirements are all decided before a GC prices anything, which is why the industry leans so heavily on feasibility studies — and why experienced car wash design-build teams, who have priced these decisions dozens of times, carry the pipeline described below. 05 — VariationFormat and regional spreadFormat is the dominant axis of car wash cost, with region layered on top — the same express prototype swings seven figures between a Sunbelt outparcel and a Northeast corner. Six representative cells:Express tunnel, Sunbelt growth corridor$3.85-6M all-inThe industry’s default build: cheaper land and merit-shop labor keep totals near the bottom of MMCG’s $3.85M+ range and the Tommy’s FDD low ends. Texas, Florida, and the Southeast absorb the largest share of the 600-700 annual new builds (ICA).Express tunnel, Northeast / West Coast metro$6-10M+ all-inUnion or high-wage labor, entitlement timelines, and corner land push projects toward MMCG’s over-$10M end — its documented example carried $4.2M of land at $3.1M/acre plus $740/SF hard costs.In-bay automatic at fuel / c-store$500K-1.2MThe volume format: about 29,000 US units (ICA). Usually built as an accessory structure on an existing fuel site, so land is sunk cost and the budget is equipment-led, with touchless packages at $400-450K.Self-serve, 4-6 bays, secondary market$150K-600KAt $15-30K equipment plus $20-70K construction per bay (trade estimates), a 4-6 bay site with vacuums and payment systems stays in the low six figures — the lowest-capex entry into the industry, on the cheapest land.Franchise express prototype$5.0-8.5MTommy’s Express FDD Item 7 across 90/110/130-ft tunnels, land through opening, including the $50K franchise fee. Other national express franchises publish comparable Item 7 ranges, making FDDs the best free benchmarking library in the sector.Prime-corner land premium markets$1M-4.2M land aloneWhere daily traffic counts justify it, land becomes the biggest line: 40% of MMCG’s $10.47M example. Operators pay it because express economics are traffic-driven — the corner is the revenue model.The practical read: format selection sets the capex order of magnitude, region sets the multiplier, and land discipline separates the pro formas that work from the ones that don’t. A developer holding express-tunnel revenue assumptions against in-bay capex, or Sunbelt land assumptions against a coastal corner, is off by 2x before breaking ground. 06 — TrendThe express boom and the roll-up waveExpress tunnels are the growth engine of the industry: the segment accounts for roughly half of US car wash revenue and has grown around a 6% CAGR, against an industry ICA sizes at about 62,750 US wash and detail outlets — roughly 17,500 conveyors, 29,000 in-bay automatics, and 16,250 self-serves — adding 600-700 new locations a year. The subscription membership model is what changed the math: recurring revenue turned single sites into fundable multi-unit programs, and turned the format into an institutional asset class.Private equity followed. Roughly $10 billion of PE capital entered the industry between 2019 and 2022, deal volume peaked at 211 transactions in 2022, and multiples touched 20x EBITDA (Car Wash Advisory / Amplify data). The consolidation is still reshaping the league table: in 2025 Oaktree-backed Whistle Express bought Driven Brands’ roughly 380-site Take 5 Car Wash portfolio for $385 million, instantly becoming the largest US operator, while Mister Car Wash operates on the order of 400-476 locations and keeps adding roughly 35 ground-up builds a year.The 2026 tone is more measured: ICA’s CAR WASH Pulse Q4 2025 survey found operators bracing for slower growth in 2026 even as consumer demand stays resilient, and construction-side escalation — commercial costs up about 6% year over year with Section 232 steel and aluminum tariffs pressuring tunnel frames and canopies — is squeezing new-build returns. The pipeline has shifted from land-rush speed to disciplined multi-unit programs run by repeat design-build teams, which is exactly where the workforce pressure now sits. 07 — WorkforceWho builds 600 car washes a yearCar wash construction has professionalized into a specialist niche. A tunnel is a small building with outsized MEP: high-volume water and reclaim piping, heavy electrical service for dryers and vacuums, and equipment integration that generalist GCs misprice — which is why dedicated car wash design-build firms and repeat GC-equipment-installer teams now carry most of the 600-700 annual new builds. Multi-unit operators and PE-backed platforms compound the demand: a chain opening 20-35 sites a year needs traveling superintendents, site-focused construction project managers, and preconstruction leads who can repeat a prototype across jurisdictions, plus the civil and utility crews every 1-1.5 acre site consumes.Those roles are being hired against the same Sunbelt retail-construction labor pool building QSRs, c-stores, and pad sites, and program-level construction leadership — people who have delivered ten washes, not one — is the scarce tier. iRecruit is building its network of commercial and retail-program construction talent, project engineers through multi-unit construction executives, ahead of that rollout demand; see our commercial development sector page for the broader market.For the hiring side of this market, see the Commercial Development practice. 08 — FAQFrequently asked questions How much does it cost to build a car wash?+Between roughly $150K and $10M+ depending on format: self-serve sites start around $150K, in-bay automatics run $500K-1.2M, and ground-up express tunnels run about $3.85M to over $10M all-in, with the Tommy’s Express 2025 FDD range at $5.0-8.5M including land.How much does an express car wash tunnel cost to build?+Franchise disclosure filings put a complete express tunnel at $5.0-8.5M (Tommy’s Express 2025 FDD, 90-130 ft tunnels), of which construction is roughly $2.1-3.9M and equipment $1.4-2.1M; independent builds in cheaper markets can land in the $2.6-4M range per Car Wash Advisory and EB3 estimates.Is building a car wash profitable?+The economics attracted roughly $10 billion of private equity from 2019-2022 at multiples up to 20x EBITDA, and Tommy’s Express FDDs have disclosed average franchise unit sales around $1.83-1.88M against a $5-8.5M build cost. Returns are site- and membership-driven, and ICA’s Q4 2025 survey shows operators expecting slower growth in 2026 — benchmark data, not investment advice.How much of a car wash budget is equipment?+Typically $1.4-2.1M for an express tunnel — roughly 16-30% of the all-in project depending on land cost (16% of MMCG’s $10.47M example, more in cheaper markets). In-bay automatics invert the ratio: touchless equipment at $400-450K can be the largest single line.How are car wash builds financed?+Most commonly through SBA programs: an SBA 504 structure can finance up to 90% of project cost (e.g., a $3M build split $1.5M bank, $1.2M SBA, $300K down), though lenders note start-up washes usually need about 20% down and a bankable feasibility study. Factual description of common structures, not financing advice. Rollouts run on repeat buildersOpening multiple sites a year? Program-level construction leadership is the scarcest line in the budget. iRecruit is building its network of commercial and retail-program construction talent — project engineers through multi-unit executives — ahead of the express car wash and pad-site rollout wave.Scope a search →Candidates — register with us →
