Cigar Lounge Builder in Denver: Home Cigar Rooms and Commercial Lounges

A cigar room only works if the smoke stays in it. Get the air wrong and the whole house smells like last Saturday. Gribbons Group Corp is a licensed & insured general contractor that plans and builds home cigar rooms and lounges across the Denver metro.

We also work with owners on commercial cigar lounge build-outs.

The first half of this page is for homeowners. The second half is for business owners, where Colorado’s smoking law, local licensing, and commercial review decide what can be built.

Home Cigar Rooms

Colorado’s Clean Indoor Air Act doesn’t apply to private homes, except when a home is being used for child care or day care. So a cigar room in your house is a design and construction question, not a licensing one.

If you live in a condo or townhome, check your HOA’s rules and remember that the Act does cover common areas like hallways and lobbies in multi-unit buildings.

Basements work well because the room can be isolated and exhausted through an outside wall. If you’re finishing the rest of the basement too, see what you can put in a finished basement.

Smoke evacuation and air exchange

This is where most cigar rooms fail. A ceiling fan, a cracked window, or an air purifier won’t clear cigar smoke. What works is a ventilation system designed for the room:

• Dedicated exhaust to the outdoors. A fan sized for the room’s volume and for how many people will be smoking at once, ducted straight outside and never into an attic, soffit, or the home’s return air.
• Makeup air. Air you exhaust has to be replaced. We plan a fresh-air path so the fan can move air without pulling it from the rest of the house.
• Negative pressure. The room should run at slightly lower pressure than the rest of the house, so when the door opens, air flows in, not out.
• Placement. Exhaust grilles high and near the seating; supply air low and across the room, so smoke sweeps toward the exhaust.
• Combustion safety. A strong exhaust fan in a basement can backdraft a nearby furnace or water heater that vents naturally. Makeup air and a check of your mechanical room are part of our design, not an afterthought.

Sealing the room from the house

Ventilation only works if the room is tight. Smoke finds every gap:

• Walls and ceiling air-sealed, with sealed electrical boxes and penetrations.
• No shared supply or return ducts with the rest of the house, so the furnace can’t spread smoke to every room.
• A solid door with full perimeter seals and a drop seal or tight threshold.
• Attention to the ceiling: in a basement, the floor system overhead is the easiest path for smoke upstairs.
• Wipe-down surfaces, since residue settles on everything.

Humidor integration

A humidor can be a cabinet, a built-in with a glass front, or a small walk-in room. Cigars are commonly stored around 65–70°F and 65–70% relative humidity, and the construction has to hold that steadily:

• A properly placed vapor barrier and insulation so moisture stays inside the humidor and out of your walls.
• Spanish cedar lining and shelving.
• Humidification and, where needed, cooling, with power planned before drywall.
• Well-sealed glass doors, so the collection is on display.
• Separation from the smoking area, so stored cigars don’t sit in smoke.

Bar, seating, and finishes

The room should feel like a lounge, not a ventilated closet. Common pieces: a wet bar with sink and under-counter refrigeration, cabinetry, a TV wall with low-voltage rough-in, dimmable lighting, and durable finishes like wood paneling, leather, and hard flooring. We avoid heavy fabrics that soak up smoke.

Commercial Cigar Lounges

A lounge open to customers is a different project. The business has to fit Colorado’s smoking law and local licensing, and the build has to pass commercial building and fire review. We confirm requirements with your city before design. Here is what official sources say.

This section summarizes official sources as of September 2026. It isn’t legal advice, and laws change; confirm with your attorney, the state Liquor and Tobacco Enforcement Division, and your city.

The Colorado Clean Indoor Air Act

Under the Colorado Clean Indoor Air Act (C.R.S. 25-14-201 and following), smoking is prohibited in most indoor areas, including any place of employment, bars, and food service establishments.

The Act was updated in 2019 by HB19-1076, which added e-cigarettes and removed several older exceptions. The Colorado Department of Public Health and Environment summarizes it as requiring most indoor workplaces and public places to be smoke- and vapor-free.

Two exemptions matter:

• Cigar-tobacco bars, which must meet all three of these conditions:
  • Qualified in 2005 (5% of gross income or $50,000 from on-site tobacco and humidor rentals, vending excluded) and every year since
  • Same size and location as on Dec 31, 2005
  • No one under 21, with the required 4×6-inch sign
• Retail tobacco businesses. The Act also exempts retail tobacco businesses, and it defines a tobacco business as one engaged primarily in the sale of tobacco products or smoking devices and accessories, where the sale of other products is merely incidental. These businesses must also keep out anyone under 21 and post the required sign.

What that means for construction: the cigar-tobacco bar exemption is tied to 2005, so a new bar can’t qualify and an existing one can’t expand or move. Bars and restaurants are smoke-free under the Act, so a new business built mainly around drinks or food can’t allow indoor smoking.

A new lounge that allows smoking generally has to qualify as a retail tobacco business: tobacco sales are the main business, other sales are incidental, no one under 21 enters, and it holds the state on-premises tobacco license plus any local license.

Denver’s tobacco program, for example, says hookah retailers can’t serve or allow alcohol on site. Ventilation doesn’t make a space exempt. Confirm your concept with your attorney and the licensing authorities; we build to that answer.

Other provisions that affect the floor plan:

• Smoke-free work areas. An employer that owns an otherwise exempt facility must provide a smoke-free work area for each employee who asks for one. Plan an office or back-of-house space that’s sealed and ventilated separately.
• Entryways. Smoking isn’t allowed within 25 feet of the entrance of buildings covered by the Act. Local governments can set a larger radius, and a few local rules adopted before 2019 set a smaller one.
• Local rules. Cities and counties may adopt their own smoking rules, but not weaker than the state’s.

Tobacco retail licensing

Since July 1, 2021, Colorado has required retailers to hold a tobacco retailer license from the Liquor and Tobacco Enforcement Division to sell cigarettes, tobacco products, or nicotine products.

The Division’s tobacco FAQ explains that an on-premises retail license allows smoking or vaping inside the licensed premises and an off-premises license does not, and it recommends confirming whether you also need a local license.

Local licensing varies. In Denver, for example, the city requires every business that sells tobacco products to hold a retail tobacco store license.

New Denver locations generally can’t be within 1,000 feet of a school, a city-owned recreation center, or a city-owned outdoor pool. The city lists limited exemptions for locations that sold tobacco before 2021.

Other cities have their own rules, so we confirm requirements with your city before design, and before you sign a lease if we can.

Commercial mechanical and ventilation

In a commercial space, the ventilation isn’t just about comfort. Smoke has to stay inside the lounge and out of neighboring tenants’ spaces and smoke-free work areas. That typically means:

• A ventilation design from a licensed mechanical engineer, sized for the room and expected occupancy.
• Dedicated exhaust with makeup air, and the lounge held at negative pressure relative to adjacent spaces.
• Exhaust discharge placed away from air intakes, windows, doors, and neighbors.
• Coordination with the landlord on roof penetrations and shared ducts.

In Denver, commercial tenant-finish projects go through a building plan review that can include mechanical, electrical, plumbing, and fire disciplines, and plans prepared by an architect or engineer must carry their seal and signature.

Fire code and life safety

Commercial lounges also go through fire review. In Denver, the fire department requires plan review to confirm compliance with the fire code before building or installation permits are approved, and fire alarm and sprinkler work is permitted separately through the city’s fire construction permits.

Suburban cities and fire districts handle this their own way, so we confirm requirements with your city before design.

Licensing for commercial work

Cities license contractors by the type of work; Denver, for example, requires a valid contractor’s license for the type of work covered by the permit. Before we scope a commercial lounge, we confirm with the city which contractor license the permit requires and tell you plainly whether we can pull it or how the project needs to be structured.

How a Cigar Room Project Works

1. Site visit. We look at the space, exhaust routes outside, nearby mechanical equipment, and electrical capacity.
2. Requirements check. Permits and HOA rules for homes; for businesses, we confirm requirements with your city before design.
3. Written scope and estimate. Ventilation, sealing, humidor, bar, and finishes spelled out line by line.
4. Design, permits, and build. Drawings, mechanical design, permits, and inspections before walls close, then finishes and a final walkthrough.

More on how we work is on our process page.

Licensed & Insured

Gribbons Group Corp is licensed & insured and holds these contractor licenses: Douglas County #A260170, Jefferson County Class B #1028872, City of Littleton #AEC002126, and City of Arvada #AEC13870. We confirm the permitting jurisdiction for your property during the first conversation.

Related spaces people often build alongside a cigar room: home theaters, custom wine cellars, and home spas and saunas. And if the room is part of a bigger project, start with what you can put in a finished basement. Most of these rooms go in as part of a basement finish; see our pages for Denver, Lakewood, Aurora, Centennial, Parker, and Castle Rock.

Cigar Lounge FAQs

Can I smoke cigars in a room in my house?

Colorado’s Clean Indoor Air Act doesn’t apply to private homes unless the home is being used for child care or day care. In condos and townhomes, check your HOA rules; the Act does cover common areas in multi-unit buildings.

How do you keep cigar smoke out of the rest of the house?

A dedicated exhaust fan ducted outdoors, planned makeup air, a sealed room held at negative pressure, no shared ductwork with the house, and a sealed door.

Can I open a new cigar bar that allows smoking in Colorado?

Not as a bar. The cigar-tobacco bar exemption covers only bars that met the sales threshold in 2005 and haven’t expanded or moved since. A new business can allow smoking only if it qualifies another way, most often as a retail tobacco business whose main business is selling tobacco, with no one under 21 and the required state and local licenses. Confirm with your attorney and the licensing authorities before you sign a lease.

Do I need a license to run a cigar lounge?

Colorado has required a tobacco retailer license from the Liquor and Tobacco Enforcement Division to sell tobacco products since July 1, 2021, and some cities, including Denver, require their own. Denver requires a retail tobacco store license. We confirm local requirements before design.

How much does a cigar room cost?

Room size, ventilation design, exhaust run length, humidor type, bar plumbing, and finishes drive cost. You get a written, itemized estimate after a site visit.
