How To Build A Carwash In Colorado: Plan To Profit Or Plan To Fail

Asher Architects + Engineers designed the Washway Car Wash in Greeley ( a 3,760 square foot tunnel-style facility built for up to 500 cars per day) and the most important decisions made on that project happened before a single permit was filed.

That’s the part most first-time investors miss.

Colorado is genuinely one of the better states in the country to own a carwash. Dusty roads, ranch trucks caked in mud, winter salt and grime on every vehicle from October through April,  the demand is real, consistent, and largely recession-resistant. Add a growing population along the Front Range and you’ve got the conditions that make a carwash a compelling passive income idea for the right investor.

The problem is this: there is a HUGE question mark and plenty of landmines between “this sounds like a great investment” and opening day.

Most first-time investors underestimate the complexity. They find a piece of land, run some back-of-napkin math on car counts, and assume the rest is a construction problem. It isn’t. Figuring out how to build a carwash in Colorado is as much a design, engineering, and site strategy problem as it is a business one. 

The investors who get that right from the start are the ones who actually open on time, hit their throughput targets, and build something worth replicating.

The ones who don’t end up with expensive concrete slabs and a story they’d rather not share at the dinner table.

The “If You Build It, They Will Come” Trap

There’s a version of passive income ideas that sounds like this: buy cheap land, put up a building, collect revenue. Carwashes, laundromats, and storage facilities attract this thinking because the model looks simple on paper: low staffing, high volume, recurring membership revenue.

But the carwash that sits half-empty on a county road between two fields didn’t fail because of its equipment. It failed before the permit was pulled. Cheap land with low visibility and no natural foot traffic is one of the most common and most expensive mistakes in commercial real estate investment. People driving from Point A to Point B on a rural route don’t detour for a carwash. They stop where they’re already slowing down, filling up, or grabbing a quick bite.

Site selection isn’t just about price per acre. It’s about co-tenancy, traffic patterns, ingress and egress geometry, stacking lane length, and whether the surrounding land use puts your target customer within 300 feet on a daily basis. You can’t neglect this when it comes to planning how to build a carwash in Colorado.

The Washway Car Wash in Greeley (designed by Asher Architects + Engineers and built by McCauley Constructors) sits at 3501 W 4th Street, sharing a commercial corridor with a 7-Eleven and a Conoco station. Not to mention the fact that all of this is across the street from a neighborhood! That’s not a coincidence. That’s strategy. Customers are already stopping. Washway just gave them one more reason.

What You’re Actually Building

Understanding how to build a carwash in Colorado means understanding that a carwash is not a simple commercial building. It is a specialized facility with mechanical, civil, structural, and architectural requirements that interact in ways that will absolutely find the gaps in a disconnected execution team. You need an integrated architectural team who can execute. Anything less results in failure.

Water systems and reclamation. Colorado has strict regulations around water usage and reclamation for commercial carwash facilities. Your drainage design, reclaim systems, and water handling aren’t afterthoughts — they’re permit requirements. Get them wrong and you’re redesigning mid-construction (and paying for that, too).

Cold weather engineering. A heated soft-touch conveyor isn’t a luxury feature in Colorado — it’s an operational necessity. Freeze protection for equipment enclosures, heated entry and exit transitions, and envelope design that keeps the wash tunnel functional at 10 degrees are design decisions that have to be made before the foundation is poured, not after the first hard freeze shuts you down.

Traffic flow and throughput. Washway’s tunnel runs 110 feet and is designed to handle up to 500 cars per day. That number doesn’t happen by accident. It’s the product of stacking lane design, vacuum bay layout (17 bays at the Greeley location), and a site plan that moves cars in, through, and out without creating bottlenecks that back up onto the street and frustrate customers before they’ve even reached the tunnel entrance.

Truck-friendly design. In Greeley, and across the Northern Colorado market, you are designing for ranch trucks, work trucks, and dually pickups. Washway’s extra-wide tunnel configuration is a deliberate market response — a design decision that expands the addressable customer base on day one. That decision lives in the architecture, not the equipment catalog.

The Hornet’s Nest Nobody Tells You About

Most passive-income hopefuls think an investment property is all about securing capital. They get a business plan ready, secure a loan, and can practically see the cash printing.

Until reality strikes. Construction stalls. They don’t know who to call. 

And nobody knows anything because the project isn’t centralized with competent leadership.

Here’s what figuring out how to build a carwash in Colorado actually looks like when your execution team is fragmented:

Your architect designs the building. Your civil engineer ( hired separately) designs the site plan and drainage. Your structural engineer (also separate) handles the foundation and framing. Each firm has its own schedule, its own communication chain, and its own liability boundary. When something doesn’t coordinate (and something always doesn’t coordinate) you find out during construction, which is the most expensive time to find out.

Change orders. Schedule delays. Carrying costs on a loan while three consultants argue about whose drawing was wrong. This is not a hypothetical. It is the standard outcome when a first-time commercial investor assembles a team piecemeal because they were optimizing for the lowest individual bid rather than the tightest execution.

Carwash as an investment only works if you open on time, operate at capacity, and don’t bleed capital during construction. Every week of delay is revenue that doesn’t exist. Every change order is margin that disappears. The business model that looked great on a spreadsheet starts to erode the moment the project loses momentum.

How Washway Did It The Right Way

Asher Architects + Engineers is one of the few firms in Northern Colorado that brings architecture, civil engineering, structural engineering, and landscape architecture under one roof. For a project like Washway, that integration isn’t a convenience; it’s the difference between a coordinated permit set and a coordination nightmare.

The civil team that designs the drainage and water reclamation system is in the same building as the architect designing the tunnel envelope. The structural engineer reviewing the foundation loads is talking to the same team that specified the equipment clearances. There are no handoff gaps, no version-control problems between separate firms, and no delay cycles waiting on a third-party consultant to respond to an RFI.

The result is a 3,760 square foot facility that functions exactly as designed: a high-throughput, truck-friendly, cold-weather-ready carwash with a membership model built for the Greeley market, opened by a first-time owner who is already planning his next location.

That’s how carwash as an investment is supposed to work.

If you’re wondering about how to build a Carwash in Colorado the right way, just like Washway, you owe it to yourself and your team to give us a call.

When it comes to passive income solutions, risk mitigation is everything and there’s only one team we know of that handles everything from end to end.
