TL;DR
Colorado sells no statewide window-washer license. Year-one money goes to an EIN (free), an optional LLC and trade name, city or county business licenses, insurance, and gear. A solo sidewalk route can be paper-ready in days once filings post. High glass adds fall-protection cost fast. Confirm every fee with the board that collects it.
How much does storefront windows cost in Colorado?
A first-year storefront route in Colorado costs more in insurance, local paper, and gear than it ever will in a state license. Colorado does not sell a window-washer card. Your cash goes to an optional LLC, a city or county business license, liability and auto insurance, and a water-fed pole you can carry down a sidewalk.
Nobody has a clean public dataset for what a Colorado storefront route costs. The closest official numbers are filing rules, tax rates, and wage floors. A national blog roundup is not the clerk in the city you plan to invoice.
Stay on the ground with no employees and a tight year-one cash number often lands in the low thousands once insurance binds. That is a practitioner range, not a CDLE statistic. A van RO rig, a lift, and a W-2 helper change it in a hurry.
Skip the branded buildout and the territory package. Waste of money for retail glass. Price the certificate of insurance first. Property managers read that sheet more closely than they will ever look at your pole.
| Cost bucket | Who sets it | What you actually do |
|---|---|---|
| State occupational license | Colorado DPO | None for washing storefront glass. Check the profession list yourself. [8] |
| Entity filing | Colorado Secretary of State | File an LLC only if you want the wrapper. Confirm the live fee. [9] |
| Federal tax ID | IRS | Apply online. The IRS fee is $0. [1] |
| State tax accounts | Colorado Department of Revenue | Open what your activity triggers. Confirm in Revenue Online. [10] |
| Local business license | City or county clerk | Budget time for Denver, Aurora, Colorado Springs, and Fort Collins separately. |
| Labor floor if you hire | CDLE, and Denver if you work there | Colorado's 2025 state minimum wage was $14.81 an hour. Confirm the current posting. [6] |
Pricing a route south of the state line too? storefront windows cost in Arizona is a useful contrast, because the license story flips the minute you leave Colorado.
Do you need a license for storefront windows in Colorado?
No. Colorado issues no statewide occupational license for storefront window cleaning. Window washer, glass cleaner, and building exterior cleaner are not on the Department of Regulatory Agencies profession list. [8] That is the whole state-license answer.
You still need ordinary business paper. Cities and counties issue business licenses. The IRS issues an EIN. The Secretary of State files entities and trade names. None of those are trade licenses. People mash them together and then tell you Colorado requires a license. Sloppy.
A contractor license is a different animal. Ground-level storefront work is usually not construction. You are not pulling a building permit to squeegee a bakery. High work with swings, scaffolds, or rope descent can pull in building-owner rules, OSHA duties, and sometimes a sidewalk or right-of-way permit. Ask the building department for the address you plan to wash.
Someone selling a Colorado window cleaning license course? Walk. The state did not deputize them.
Confirm the local clerk in every city on your route. Denver uses Excise and Licenses. [13] Colorado Springs, Aurora, Lakewood, and Fort Collins each run their own desk. Home-rule cities do not copy each other. License the cities you can sell this month, not a fantasy map of the whole Front Range.
How long does storefront windows take in Colorado?
Paper can take a few days if you file online and the city is simple. Building a paid weekly route takes months. Those are different clocks. No board promises a start date, and I will not invent one.
An EIN from the IRS often issues in the same session when the online application works. [1] Colorado Secretary of State processing is posted on the filing system. Confirm it there the morning you file. Do not take a blog's same-day claim as a rule. Cities range from a short business-license turnaround to a longer review if they want zoning sign-off for a home occupation.
Insurance binders depend on underwriters, not the state. Glass and height class codes can slow a quote. That delay is real and it is not on a government calendar.
Don't wait for an LLC stamp to knock on a store. You can often invoice as a sole proprietor while an entity is pending, if the city will license you that way. Some property managers will not let you on site without the LLC name on the certificate of insurance. Ask them first.
High-rise work has a longer ramp because of training, anchor checks, and owner packets. Sidewalk retail is faster. The glass does not care about your filing receipt. The manager does.
What state filings do you actually need in Colorado?
Start with structure. The SBA structure guide is enough of a map: sole proprietor, partnership, LLC, or corporation. [15] Colorado does not make window washers pick an LLC. I would still form one before I hired anyone or signed a national tenant.
File Articles of Organization with the Colorado Secretary of State if you want the LLC. Confirm today's fee and any periodic report on the LLC pages. [9] I am not going to quote a fee the board can change tomorrow.
A Statement of Trade Name is what you file if you operate under anything other than your personal legal name. Confirm that fee on the same site. Skip the trade name only if you are truly billing as your own legal name and you can live with that on invoices.
Open tax accounts with the Colorado Department of Revenue only for the taxes you actually owe. [10] Do not create a sales-tax account because a video said every business needs one. Ask CDOR whether your service is taxable before you tax a customer.
Pay wages and you also meet CDLE for unemployment insurance and FAMLI. [11] Those are employee systems, not a washer license. A solo owner with no staff can ignore most of that pile until the first hire.
Keep a folder with the EIN letter, the SOS printout, the city license, and the insurance certificate. That folder is the job. The squeegee is the easy part.
What do Colorado cities and counties add on top?
Local paper is where Colorado actually gets annoying. The state left general business licensing to cities and counties. Denver's Department of Excise and Licenses runs a business license program. Confirm the application, the fee, and whether they want a home-occupation clearance. [13]
Colorado Springs, Aurora, Fort Collins, Boulder, Lakewood, Thornton, and the mountain towns each have a clerk. A Front Range route that crosses five cities can mean five licenses. That is the real Colorado license problem.
Some cities want a contractor registration if you present as a building contractor. Read their definition. Washing glass sits closer to janitorial or maintenance. If a clerk says you need a construction contractor license to wash a nail salon, ask them to show the code section. Then comply or appeal. Don't guess on the counter.
HOA and zoning rules can block a trailer at a house. Check that before you buy tanks. A cease-and-desist from an HOA wastes more time than the Secretary of State ever will.
Compare the local-license pile to storefront windows cost in California if you already know city business tax certificates. The habit is similar. The forms are not. For a smaller-state stack, storefront windows cost in Idaho is a cleaner read.
How much is insurance for a Colorado storefront route?
Budget insurance before fancy poles. Property managers in Denver and Boulder commonly ask for general liability, often $1 million per occurrence. That dollar figure is a market habit, not a Colorado statute. I have not seen the state set a GL minimum for window washers.
Ask the broker for glass breakage, third-party property damage, and completed operations. A cheap policy that excludes glass is a waste. You will find out on the first cracked lite.
Commercial auto matters if the vehicle is used in the business. Personal auto policies often deny business use. Read yours. A denied windshield claim on I-25 is a bad way to learn the exclusion.
Workers' compensation is required once you have employees. Colorado's Division of Workers' Compensation tells employers they must secure compensation. [7] Solo owners without employees are usually outside that duty. Confirm your facts with the Division or a carrier. Get a quote. I will not invent a premium.
Umbrella coverage is optional in year one. Skip it until a national retailer asks in writing. Pay for the certificate the manager already put in the vendor packet.
What does storefront window equipment cost in Colorado?
Ground-floor storefront work in Colorado is mostly a water-fed pole, a pure-water source, a squeegee for interiors, towels, and a way to haul it. Retail listings for a basic pole kit commonly sit in the mid hundreds. Full van-mounted RO/DI systems run into the thousands. Those are vendor prices, not state fees. Confirm with the seller the week you buy.
Want a simple starting kit? StorefrontWash sells a $149 one-time Pure-Water Pole Route Kit. You do not need it to be legal. A used pole from a local washer who quit works too.
Ladders on a windy downtown job are how people get hurt and get sued. Don't build year one around ladders. Stay on the sidewalk pole for exterior retail glass.
A lift is a waste for a first storefront route. So is a full vehicle wrap. A pressure washer you use to blast paint off a mullion will eat a claim.
Winter on the Front Range is freeze and chinook in the same week. Budget extra towels and a place to keep tanks from bursting. That costs more than people from the desert expect. storefront windows cost in Illinois is another cold-weather picture if you want a second state's paper and ops next to this one.
What taxes hit storefront windows in Colorado?
Plan for federal self-employment tax if you are not taking a W-2 from your own corporation. The IRS says, "Self-employment tax is a tax consisting of Social Security and Medicare taxes primarily for individuals who work for themselves." [2] The combined rate is 15.3 percent (12.4 percent Social Security plus 2.9 percent Medicare), with Social Security applying only up to the annual wage base the IRS posts each year.
The IRS does not charge a fee to apply for an EIN online. [1] Use that number on the city license, the SOS filing, and the insurance application so the names match.
Colorado also has a flat individual income tax. The rate is set in statute and sometimes adjusted. Confirm the rate for the tax year on the Department of Revenue individual income tax pages before you price your draw. Do not copy a 2022 blog.
State sales tax generally targets tangible personal property. A pure cleaning service is often outside that net, but home-rule cities write their own rules and CDOR updates guidance. Confirm taxability with CDOR before you add tax to an invoice. [10] Charging tax you do not owe is sloppy. Failing to charge tax you do owe is worse.
Sell bottled product or new blades off the truck and that sale can be taxable even when the wash is not. Keep mileage and supply receipts. That is boring, and it is where sole proprietors leak money.
What does a helper cost once you hire in Colorado?
Hire late. A helper looks cheap until you add the paper.
Colorado's 2025 state minimum wage was $14.81 an hour, according to CDLE. [6] Denver posts a higher city minimum. Confirm both the week you hire, because Colorado adjusts the state floor and Denver sets its own. Overtime and workplace postings sit in the COMPS Order. Read the current order, not a summary card from three years ago. [14]
Once you have employees, workers' compensation stops being optional. [7] Unemployment insurance registration sits with CDLE. FAMLI premiums apply to covered wages. Confirm the current FAMLI percentage on the employer page rather than trusting a podcast. [11]
Worker classification is a fight Colorado takes seriously. If you 1099 a helper who only works your route, with your pole, on your schedule, you are asking for an audit. I would W-2 the first helper.
I-9 and the EIN come first. The EIN is still $0. [1] Skip payroll apps that do not file Colorado withholding. The first missed quarterly filing costs more than a proper payroll month.
What safety and water rules cost money in Colorado?
Federal OSHA covers private employers in Colorado. The walking-working surfaces rule is blunt. "Except as provided elsewhere in this section, the employer must ensure that each employee on a walking-working surface with an unprotected side or edge that is 4 feet (1.2 m) or more above a lower level is protected from falling by one or more of the following:" [3]
OSHA requires fall protection at 4 feet on general industry walking-working surfaces. That number surprises people who think the duty starts at 6 feet, which is a construction habit, not this rule.
Rope descent systems have their own section. Training, equipment, and identified anchorages sit on the employer. [4] Personal fall protection systems are specified in 1910.140. [5] Never leave the sidewalk? You still need a plan for interiors with atriums and for the one client who asks you to just hop on the canopy.
Wash water belongs in a sanitary drain or on landscaping that can take it, not in the storm inlet. EPA's municipal stormwater work is why cities ticket people who soap a sidewalk into a grate. [12] Pure water with no detergent is easier to defend. Still do not dump a tank into a storm drain and argue about it.
Don't bid swing-stage work in year one. The safety packet and the insurance will eat the profit.
Does Denver cost more than the rest of Colorado?
Yes, on wages, parking, and how picky the vendor packet is. Denver metro has the licenses, the higher city minimum wage, the property-manager certificate culture, and weather that freezes a hose at 7 a.m. then melts it by noon. Confirm Denver's current minimum on the city's own posting the week you hire. Confirm the business license on Excise and Licenses, not a Facebook comment. [13]
Mountain towns add seasonal shutdowns, HOA gates, and clerks who only process licenses on certain days. Confirm that in person. A two-hour drive for a stamp is still cheaper than working without it and getting shut off.
Colorado Springs and the south metro often feel faster than Boulder. Boulder will care about the creek and the downtown mall rules. I-70 corridor work is real money and a real drive. Price windshield time or you will donate it.
Running ski-town storefronts in winter and Front Range in spring? You are running two businesses. Budget two insurance conversations if vehicles live in two places.
For a coastal paper path, storefront windows cost in Florida shows how contractor habits change the same trade. storefront windows cost in Alaska is the extreme-season version of the mountain problem.
What is worth buying in year one, and what is a waste?
Pay for liability insurance that actually covers glass. Pay for the local licenses on the cities you will invoice this month, not a theoretical 20-city map. Pay for a pole you can run in wind. Pay a bookkeeper for the first quarterly estimate.
Skip the lift in year one. Skip the wrap. Skip any course that pretends Colorado sold them a trade license. Skip hiring until weekly accounts cover a W-2, workers' comp, and your own time to redo missed panes. [7]
A cheap pressure washer is how you etch glass and then work for free. Don't.
If a bid needs rope descent, either subcontract to someone who already runs the OSHA program or walk. [4] The 4-foot fall rule still applies on ordinary walking-working surfaces, so do not treat a low canopy as a freebie. [3]
Revisit the Secretary of State and CDOR accounts after the first month so periodic reports and withholding do not surprise you. [9] [10] Boards change instructions. Refresh the page. Do not run last year's printout.
How does Colorado compare to other states for this trade?
Colorado is a no-state-trade-license, many-city-licenses state. That is friendlier than states that run contractor boards for any exterior work, and messier than states with one statewide business license.
The work on the glass is the same. The folder in your passenger seat is not. Pricing a move? Read storefront windows cost in Georgia next to this page and notice how local occupational tax and state paper diverge.
StorefrontWash is an independent publisher, not a law firm and not a service company. Want a paper checklist next to a starter pole? Use /start. Confirm every fee and processing note with the board that collects the money. Nobody here can approve you or time your first invoice.
Frequently asked questions
Do you need a license for storefront windows in Colorado?
No statewide occupational license exists for storefront window cleaning. Colorado DPO does not list this trade. You still need ordinary business paper: often a city or county business license, an EIN, and any entity or trade name you choose to file. Confirm each desk that actually collects a fee. High-rise access can add site rules that a sidewalk route never sees.
How much does storefront windows cost in Colorado?
There is no official statewide price for a storefront route. Year-one cash is usually insurance, local licenses, optional SOS filings, and gear. A solo sidewalk setup often stays in the low thousands once liability binds. That is a working range, not a CDLE study. Lifts, RO vans, and a W-2 helper move the number fast. Confirm live board fees. Do not copy a national blog.
How long does storefront windows take in Colorado?
Legal paper can be done in days if the EIN issues, the city license is simple, and insurance binds. The Secretary of State posts its own processing. Confirm it when you file. No approval or timing guarantee. Selling a weekly book of accounts still takes months. High-rise owner packets take longer than a bakery walk-up.
Do I need a Colorado contractor license to wash storefront glass?
Usually no for ground-level storefront cleaning. That work is maintenance, not a building permit job. Ask the city where the glass sits whether their contractor definition catches exterior building maintenance or rope work. Comply with the code section they show you. A statewide construction card is not how Colorado licenses this trade.
Is storefront window cleaning taxable in Colorado?
Colorado state sales tax generally targets tangible personal property, not every service. A pure wash is often outside the state net, but home-rule cities write their own rules. Confirm taxability with the Department of Revenue before you tax an invoice. Blades or bottles sold off the truck can be taxable even when the wash is not.
Do solo washers need workers' comp in Colorado?
With no employees, you are usually outside the duty to carry workers' compensation. The duty attaches once you have employees. Confirm your facts with the Division of Workers' Compensation or a carrier before you skip the policy. A 1099 helper who works like staff can blow up that analysis.
Does Denver require its own business license?
Denver runs business licensing through Excise and Licenses. If you operate or solicit in the city, plan on their application and their fee, plus any home-occupation review if you run the route from a house. Confirm the current form on Denver's business license pages. A state LLC does not replace the city license.
How much is a Colorado LLC for this work?
The Secretary of State sets Articles of Organization fees and periodic report fees. Those numbers change. Confirm them on the LLC pages the morning you file. An LLC is optional for a solo washer. I would still form one before hiring or signing a national tenant. Do not treat the SOS filing as a trade license.
Can I start as a sole proprietor?
Yes. Colorado does not force an LLC on window washers. Many people start as a sole proprietor with an EIN, a city license, and insurance. Some property managers still want an LLC name on the certificate. Ask the accounts you actually want. You can form the LLC later if the work requires it.
What insurance do Colorado property managers usually ask for?
General liability at $1 million per occurrence is a common ask in Denver and Boulder vendor packets. That is a market habit, not a statute. Ask for glass breakage coverage. Add commercial auto if the vehicle is in the business. Workers' comp appears once you have staff. Get written limits from the manager before you bind the wrong policy.
Can I put wash water in the gutter?
Do not dump soapy tanks into a storm inlet. Municipal stormwater programs treat that as an illicit discharge. Keep wash water out of the grate. Pure water with no detergent is easier to defend, but it still should not go into the storm system. Use a sanitary drain or landscaping that can take it, and follow the city's rule.
What is the Colorado minimum wage I have to pay a helper?
Colorado's 2025 state minimum wage was $14.81 an hour, per CDLE. The state adjusts that floor. Denver posts a higher city wage. Confirm both the week you hire. Overtime and posting rules sit in the current COMPS Order. Do not pay last year's number because it is still in your notes.
Do I need FAMLI if I have no employees?
FAMLI premiums attach to covered wages. A true solo owner with no staff is not running a FAMLI payroll. Once you pay covered employees, register and confirm the current premium on the FAMLI employer page. Do not copy a rate from an old article. CDLE publishes the live figure.
Are water-fed poles allowed on public sidewalks?
A pole on a public sidewalk is ordinary pedestrian use if you do not block the walk, create a trip hazard, or violate a mall or downtown rule. Some districts limit hoses, buckets, and closed sidewalks. Ask the city for that block. A pole does not replace fall protection if anyone leaves the ground.
