TL;DR
Colorado does not license storefront window cleaning as a statewide trade. You form a business with the Secretary of State, pick up any city or county business license where you operate, and open a Department of Revenue account if your sales are taxable. Workers' comp and unemployment apply once you hire. Confirm every current fee with the office that issues the form. Ground-based poles handle most storefront glass.
Do you need a license for storefront windows in Colorado?
No. Colorado does not issue a statewide occupational license for storefront window cleaning. The Division of Professions and Occupations publishes the list of professions it actually regulates, and this trade is not on it. Confirm the current list yourself before you spend a week on hold. [10]
You still need business paper. People mash those two ideas together and stall for months.
A trade license says a board cleared you to do the work. A business license says a city will let you invoice inside its limits. Colorado skipped the first one for storefront windows. Cities did not skip the second. Denver runs business licensing through the Department of Excise and Licenses. Smaller towns use the clerk. [11]
Do not call DORA about a window washer card. You will get a polite dead end. File with the Secretary of State and the city where your first accounts sit.
High-rise work is a different safety conversation. Roof anchors and building engineer packets show up on towers. That is still not a Colorado state license. It is access control and fall gear. Most new storefront routes never touch that world.
If you want the license question in one place, use the storefront windows license in Colorado guide. Neighboring states do not all work this way. How to start storefront windows in California is a heavier contractor story. Arizona is closer to Colorado: local paper, no state trade card. The Arizona license breakdown is worth a skim if you also wash in the Four Corners.
| Paper | Who issues it | When you need it |
|---|---|---|
| Statewide trade license | No Colorado board | You do not |
| Articles of organization | Colorado Secretary of State | When you form an LLC |
| City business license | City clerk or Denver Excise and Licenses | Where you operate |
| Sales tax license | Colorado Department of Revenue | If you make taxable retail sales |
| EIN | IRS | Banking, insurance, hiring |
| Workers' compensation | A licensed carrier, overseen by CDLE | When you have employees |
How much does storefront windows cost in Colorado?
There is no honest single number. Anyone who hands you a statewide startup total for Colorado window work is padding a sales page.
State filing costs are small. Insurance, a vehicle, and water gear are not. The Colorado Secretary of State posts a public fee schedule for articles of organization, trade names, and periodic reports. Read that schedule the morning you file. Do not copy a fee off an old article. [1]
A Department of Revenue sales tax license is the next stop if you make retail sales. Check the current sales tax license page for any fee before you submit. [3]
The money that actually hurts is a van payment you cannot cover in February, plus a liability policy, plus a pure-water setup you barely use. Do not finance a new cargo van for a 10-stop route. Drive what you have until the route is real.
Quotes for general liability move with claims history, ladder use, and employees. Get three brokers. Tell them you work from the ground if that is true. A policy that thinks you hang off roofs will not price like a sidewalk pole route.
What you charge customers is looser still. Downtown Denver glass is not a Fort Morgan strip center. Height, bird mess, and weekly versus monthly all move the ticket. I walk up and quote for 90 days, then lock recurring routes. A statewide rate card just makes you underbid the ugly stops and overbid the easy ones.
If you want a cheap way to test pure-water work before you buy a trailer system, StorefrontWash has a $149 one-time Pure-Water Pole Route Kit. Skip it if you already own a pole and a deionizer. The kit does not replace the city license.
How long does storefront windows take in Colorado?
The wash is fast. The paper is the wait, and nobody can promise your clock.
An EIN from the IRS is immediate when the online application works. It is free. [7] A Colorado LLC filing is often quick online. That is not a guarantee. The Secretary of State does not owe you a same-day stamp. Check the current processing note on the LLC page before you schedule a first job. [2]
City licenses are the wildcard. Denver Excise and Licenses is not the same desk as a town clerk in Alamosa. Some portals issue in a day. Some want zoning. Call the clerk. Do not plan a launch around a blog's timing claim.
Insurance binders take a few days, sometimes longer if the underwriter asks about roofs or helpers. Answer those questions straight. Ground-only work is a different risk than ladders.
You can invoice as soon as the city says you can operate and the liability policy is active. Building a route that pays rent takes months. Anyone selling a two-week full book is selling a story.
Periodic reports come due every year in your anniversary month. Put that on a calendar the day you file so the company does not go delinquent while you are out on a route. [14]
What business structure should you file in Colorado?
File an LLC unless a CPA has a specific tax reason to do something else. A sole prop with a trade name is cheaper on day one. It also puts your personal name on every claim.
Colorado forms an LLC when articles of organization are filed with the Secretary of State. You pick a name, a registered agent with a Colorado street address, and a principal office. [2] You do not need an attorney for a single-member service company. You do need to read the form and confirm the current filing fee on the SOS schedule. [1]
After that, file a statement of trade name if you will invoice as something other than the legal LLC name. That fee sits on the same schedule. Confirm it the morning you click submit.
Get a free EIN from the IRS even if you have no employees. Banks and insurers ask for it. The IRS does not charge for an EIN when you apply on its site. [7]
Skip the professional company paperwork and the corporate stock kit. You wash glass. Do not buy a registered-agent subscription in year one if you live in Colorado and can be your own agent. That is a recurring bill for a mailbox you do not need yet.
Keep the SOS login in a password manager. The person who used a throwaway email for the filing is the person who misses the periodic report.
Do you need a sales tax license for storefront window cleaning?
Maybe. Colorado sales tax attaches to retail sales of tangible personal property and to certain services. Window cleaning is labor. Whether your invoices are taxable depends on what you sell and where the job sits.
Read the Department of Revenue sales tax license page and the sales and use tax overview before you assume you are exempt. [3][4] Do not take tax advice from a forum screenshot.
The Colorado Department of Revenue sales and use tax page states, "The state sales tax rate is 2.9%." Home-rule cities pile their own rates on top. Special districts add more. A customer in Aurora is not paying the same stack as a customer in unincorporated Weld County. Use DOR's rate lookup for the job address.
If you sell bottled chemicals, new channels, or squeegees off the truck, you are in retail. Get the license. If you only sell labor, still read the current DOR service rules. Confirm whether your mix of labor and product needs a license before the first invoice goes out.
Sales tax you collect is not operating cash. Remit it on DOR's calendar. Mix it into fuel money and you will bounce a return.
What insurance does Colorado actually require?
If you have no employees, Colorado does not force you to buy general liability. Your customers will. Property managers will not hand you keys without a certificate. That is the market, not the statute.
If you have employees, workers' compensation is not optional. Colorado employers must secure coverage for staff, and the Division of Workers' Compensation exists to enforce that. Read the current CDLE employer pages before you hire your first helper, and confirm what counts as an employee. [5]
Unemployment insurance registration sits with CDLE as well. Register as a new employer when you have staff, not when a cousin "helps on Saturdays" and you pretend they are a vendor. [6]
General liability, commercial auto, and coverage for poles and tanks are the three policies I would actually buy. An umbrella can wait until a downtown contract asks for higher limits. Do not climb unless the policy knows you climb. Tell the broker the truth.
A certificate of insurance is part of the sale on managed properties. Budget time to issue those. The broker who turns certificates around the same day is worth more than a slightly cheaper premium.
What local city and county permits do you need?
Every Colorado city that cares will want a business license or a local tax license. Denver runs this through the Department of Excise and Licenses. [11] Other cities use the clerk, the finance desk, or a portal that looks like it was built in 2008.
Counties can add a vendor license if you work unincorporated land. Home-rule cities write their own code. There is no single Colorado municipal form.
Start with the city where you sleep and the city where your first three accounts sit. If those are the same place, life is simple. If you live in Lakewood and wash in Denver, Boulder, and Cherry Creek, you may hold more than one local license. Confirm each one. Do not assume reciprocity.
HOA storefronts and downtown BIDs sometimes want proof of insurance and a vendor packet. That is private paper, not a state license. Parking a trailer overnight on a commercial street can get you towed. Ask public works.
A Secretary of State filing does not replace a Denver license. One SOS company can operate in many cities. Each city still gets to ask for its own form.
Can you work from the ground or do you need fall gear?
Most storefront glass in Colorado is reachable from the sidewalk with a water-fed pole. That is why the trade moved off ladders.
Put an employee on a walking-working surface with an unprotected side 4 feet or more above a lower level, and OSHA's walking-working surfaces rule applies. The text is blunt: "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." That is 29 CFR 1910.28. [8]
A four-foot step on a Boulder storefront is not a high-rise. It is still a number OSHA wrote down. Ladders have their own rule set. I stay on the ground unless the contract pays for the gear, the training, and the insurance rider.
Winter along the Front Range is ice and wind. A pole in a hard gust is a different tool than a pole in July. I cancel when I cannot control the pole. One cracked pane wipes a month of profit.
Cones on the sidewalk are not optional in busy cores. Customers notice. So do downtown ambassadors.
Do you need payroll accounts when you hire in Colorado?
Yes. You need the EIN you already got, Colorado wage withholding with the Department of Revenue, unemployment with CDLE, and workers' comp coverage. [15][6][5]
Colorado also runs its own wage and hour rules under the COMPS Order. Overtime, meal periods, and the posted minimum wage are not federal-only problems. CDLE publishes the current statewide minimum wage each year. Denver publishes a higher local wage. Read both posters before you write an offer, and confirm the figure on the board's page for the year you are hiring. [9]
Paying people as 1099 subcontractors to dodge this is how you buy an audit. CDLE keeps independent contractor guidance up for a reason. [12] If you set their hours, supply the pole, and send them to your accounts, they look like employees. I would rather run payroll on one helper than explain a misclassification claim.
Keep I-9s, withholding records, and the comp policy in a folder you can hand someone without digging through texts.
What taxes hit a Colorado storefront window route?
Federal income tax, Colorado income tax, and self-employment tax if you are the owner taking draws. IRS Topic No. 554 explains self-employment tax. It is Social Security and Medicare on net earnings from self-employment, at a combined 15.3 percent on the base (12.4 percent Social Security and 2.9 percent Medicare), subject to the Social Security wage base. [13]
Set aside money every month. I use about 30 percent of net as a crude reserve until a CPA says otherwise. That is a habit, not a tax opinion.
Confirm the current Colorado individual income tax rate with the Department of Revenue before you build a spreadsheet off last year's number. The rate has moved. Do not treat a blog as the statute.
Quarterly estimated payments matter once you are profitable. The IRS and DOR both expect them. A bookkeeper who has filed Colorado sales tax is worth more than a stack of new brushes.
If you later add a Texas or other out-of-state stop, do not assume the same stack follows you. How to start storefront windows in Texas and the Texas license guide are separate paper paths.
What equipment do you actually need the first year?
A water-fed pole, a way to make or buy pure water, a squeegee kit for interiors and low transoms, microfiber, a hose, a tank or resin bottles, and a vehicle that can hold wet gear without wrecking the seats.
Do not buy a huge trailer system in month one. You do not know your route density yet. Colorado's dry air and hard water make pure-water work make sense. They do not make a giant capital outlay make sense.
A 20-foot or 24-foot pole covers most single-story commercial. Two-story strip centers need more pole or a decision about ladders. I pick accounts I can do from the ground.
Winterize. Resin bottles freeze. Pumps crack. A cheap insulated box in the cargo area saves more money than a wrap on the van. Skip the wrap until the route is real.
You do not need a branded shop. You need glass that is dry before the manager unlocks, and a way to rinse without dumping dirty water on their entry mat.
How should you price storefront glass in Colorado?
Walk the store. Count glass. Note height, film, bird mess, and how often they want you. Quote a first clean higher than the maintenance visit. Recurring weekly or biweekly is the business. One-off spring cleans keep you busy and poor.
I do not use a statewide per-pane number. A Cherry Creek boutique and a Pueblo shopfront are not the same job. Fuel, parking, and wind time are part of the price.
If a property manager wants 30 doors at 6 a.m. on a Saturday, price the crew and the early clock. If they want interior partitions too, that is a different ticket.
Write the scope on the invoice. "Exterior storefront glass, ground reachable, weekly" is a scope. "Windows" is how you end up cleaning second-floor interiors for free.
Raise the recurring rate when water, insurance, or parking jumps. Do it in writing with 30 days of notice. Customers who only hired you because you were the cheapest will leave. That is fine. Those accounts were never the route.
What first-year paper should you actually keep?
Articles of organization. EIN letter. City license PDF. Insurance declarations and every certificate you sent a property manager. W-9s you collected. Mileage log. Invoices. A simple chart of accounts.
SOS periodic reports are easy to forget. Colorado sends reminders to the email on the filing. If that email is dead, you go delinquent. Put the report on a calendar the day you form the company. Confirm the current report fee on the SOS schedule. [1][14]
If you hire, keep I-9s, Colorado withholding records, and the workers' comp policy together.
I keep job photos. Not for social media. For the "you scratched our glass" call that arrives three weeks later.
This site publishes state paper guides so you can check the next form without guessing. When you are ready to kit a first pole route, start at /start.
None of this is legal advice. Confirm every fee, form, and deadline with the office that issues it. Processing times change. Fees change. The clerk in front of you beats any article, including this one.
Frequently asked questions
Do you need a license for storefront windows in Colorado?
No statewide occupational license exists for storefront window cleaning. The Division of Professions and Occupations does not list this trade. You still need a Secretary of State filing if you form an entity, plus any city or county business license where you work. Confirm both with those offices before you invoice.
How much does storefront windows cost in Colorado?
State filing fees are small and sit on the Secretary of State's public schedule. Confirm them the day you file. Real money goes to insurance, a vehicle, and water gear. Customer prices vary by city, height, and frequency. Nobody publishes a reliable statewide rate sheet, so walk-up quotes beat a copied price list.
How long does storefront windows take in Colorado?
An IRS EIN is usually immediate and free. SOS online filings are often quick, but that is not a promise. City licenses and insurance binders are the slow variables. You can take paying work once the local license and liability policy are active. A route that pays rent still takes months to build.
Do I need a contractor license to wash storefronts in Colorado?
Not at the state level for ordinary storefront window cleaning. Colorado does not run a statewide contractor card for this trade. Local building departments license construction work, which is a different pile. If a job turns into glass replacement or storefront install, stop and ask that city's building desk before you bid it.
Does a solo operator need workers' compensation in Colorado?
If you have no employees, workers' comp is generally not forced on you by the state. The moment you hire, CDLE expects coverage. Customers may still ask a solo operator for general liability. Confirm employee rules on the current CDLE workers' compensation employer pages before anyone else touches your pole.
Does Denver require its own business license?
Yes if you operate there. Denver uses the Department of Excise and Licenses, not the Secretary of State, for local business licensing. A Colorado LLC filing does not replace it. Confirm the current Denver application, any fee, and zoning questions on the city's license pages before you take 16th Street accounts.
Do I need a Colorado sales tax license if I only sell labor?
Possibly not, but do not guess. DOR taxes retail sales of tangible property and certain services. Pure labor and labor-plus-product are not the same fact pattern. Read the current sales tax license page and ask DOR if your invoices include chemicals or goods. Home-rule cities can add their own rules.
Can I pay helpers as 1099 contractors on a window route?
Only if they truly run their own business. If you set the hours, supply the gear, and send them to your accounts, CDLE will likely see employees. That triggers withholding, unemployment, and workers' comp. Read CDLE's independent contractor guidance. Misclassification is a more expensive hobby than payroll.
What is the Colorado state sales tax rate?
The Colorado Department of Revenue states that the state sales tax rate is 2.9 percent. Cities, counties, and special districts add more, so the register total runs higher than 2.9 percent almost everywhere. Look up the rate for the job address on DOR's tools. Do not reuse last year's combined rate from memory.
Do I need an EIN if I have no employees?
You can often operate as a sole prop on a Social Security number, but banks and insurers still ask for an EIN. The IRS does not charge for an EIN when you apply on its site. Get one when you form the LLC. It takes minutes when the application is up and saves a scramble later.
What OSHA height triggers fall protection on storefront work?
OSHA's 29 CFR 1910.28 requires fall protection when an employee is on a walking-working surface with an unprotected side or edge 4 feet or more above a lower level. That is a federal number, not a Colorado myth. Most storefront routes stay on the sidewalk with a pole and never hit that trigger.
Can one Colorado SOS filing cover every city I wash in?
The entity filing is statewide. Local business licenses are not. One LLC can operate in Denver, Fort Collins, and a county strip, but each jurisdiction can still want its own license or tax account. Start with the cities where you actually have keys. Add paper as the route crosses new lines.
What happens if I skip the Secretary of State periodic report?
The company can go delinquent and, if you ignore notices long enough, face dissolution. Colorado ties the report to your anniversary month. Confirm the current fee and due window on the SOS periodic report page. Put the email from the filing in a box you actually read, not a throwaway address.
Is storefront window cleaning a good first business in Colorado?
It can be if you already have a vehicle, you like early sidewalks, and you will chase recurring accounts instead of one-off spring cleans. The state paper is light. The work is weather and glass claims. I would not quit a paycheck until weekly stops cover insurance, fuel, and a tax reserve.
