Quick Answer
A restaurant buildout in Chicago usually takes 5 to 9 months from signed lease to opening day, and most of that time is design and permitting, not construction. Plan on 4 to 8 weeks for design, 2 to 4 months for permits and health plan review, and 10 to 16 weeks of construction. The cost depends far more on what the space already has than on its size. Taking over a former restaurant with a working kitchen is the cheapest path. Converting a retail space into a restaurant is the most expensive, because you are adding gas, grease, exhaust, and electrical capacity that was never there. Start your liquor license and health plan review early. They cause more delays than the build itself.
Opening a restaurant in Chicago is one of the hardest construction projects a small business owner can take on. It has more moving parts than a store, more inspections than an office, and more ways for a timeline to slip.
We have built restaurant, cafe, and franchise projects across the city and suburbs for more than 20 years. This guide covers what actually happens, in order, and where owners lose the most money.
Use it to plan your budget, your timeline, and your questions before you sign anything.
Part 1: Before You Sign the Lease
Most restaurant budget disasters are decided before construction starts. They are decided the day you sign a lease on the wrong space.
The three types of restaurant space
1. Second-generation restaurant space (the cheapest path)
A space that was already a restaurant. It has the hood, grease interceptor, gas service, floor drains, and restrooms already in place. If the kitchen layout works for your menu, you can save months and a large share of your budget.
Watch out for: Equipment that looks fine but is at the end of its life. An old hood that does not meet current code. A grease interceptor sized for a different menu. Walk it with a contractor, not just the landlord.
2. Vanilla box or white box retail space (the middle path)
Finished walls, ceiling, lights, HVAC, and a restroom, but no restaurant systems. You will be adding gas, hood and exhaust, fire suppression, grease waste, floor drains, extra electrical service, and probably a bigger water heater.
3. Cold dark shell or ground-up (the most expensive path)
A bare space with no systems at all, or a building that does not exist yet. Full control over layout, full responsibility for cost.
Our guide on retail build-out vs ground-up construction walks through this choice in detail.
What to check before you sign
- Zoning. Is a restaurant allowed at this address? Is a liquor license allowed? Some Chicago precincts vote themselves dry, and some blocks have moratoriums.
- Gas service. Is there enough gas capacity for your cook line? Adding service can mean a long utility lead time.
- Electrical service. Is the panel big enough for your equipment? A service upgrade is a major cost.
- Exhaust routing. Can the hood duct run to the roof? In a multi-story building, this is a legal and structural question, not just a mechanical one.
- Grease waste. Is there an interceptor? Where would one go? In-ground units may mean cutting the slab.
- Restrooms. Are there enough, and are they accessible? See our ADA requirements guide.
- Venting and odors. Neighbors above a restaurant are a common source of complaints and delays.
- Ceiling height and structure. You need room for ductwork above the ceiling.
- Delivery and trash. Where do trucks unload? Where does the dumpster go?
Bring a contractor to the walkthrough before you sign. A one-hour visit can save six figures. Our commercial lease build-out checklist covers what to look at and what to negotiate.
Negotiate these lease terms
- Tenant improvement allowance. How much the landlord contributes, and when it is paid.
- Free rent during construction. Permits in Chicago can take months. Rent during that time comes straight out of your opening budget.
- Who owns the systems you install. Hoods and equipment often stay with the building.
- Delivery condition in writing. “Vanilla box” means different things to different landlords. Spell out exactly what is included.
- Permit contingency. What happens if the city denies your use or your liquor license?
Part 2: Building the Budget
What drives restaurant construction costs
In order of impact:
- Existing conditions. Second-generation space versus raw retail is the single biggest factor.
- Kitchen systems. Hood, fire suppression, gas, exhaust and makeup air, grease waste, and floor drains.
- Utility capacity upgrades. New gas service or a larger electrical service can be very expensive.
- HVAC. Restaurants need far more ventilation than retail. Makeup air is often forgotten in early budgets.
- Finishes. A fast casual counter shop and a full-service restaurant with custom millwork are different budgets entirely.
- Bar. Bars add plumbing, refrigeration, drainage, and millwork.
- Square footage. It matters, but less than most owners expect.
- Accessibility upgrades. Older spaces often need entrance and restroom work.

How much contingency?
Plan on 10 to 15 percent for a second-generation space, and 15 to 20 percent for a conversion or an older building. Chicago buildings hide surprises behind walls and under slabs. The older the building, the bigger the cushion you need.
Our post on the hidden costs of retail construction covers the ones that hit hardest.
A budget rule that holds up
The number your general contractor gives you after seeing the space and the plans is the only number that matters. Per-square-foot averages you find online mix ground-up projects, conversions, and simple refreshes together. They are not a budget. Get a real bid on real drawings.
Part 3: Permits and Licenses in Chicago
This is where most timelines slip. Chicago restaurants need approvals from several departments, and they do not all run at the same speed.
Building permits
Most restaurant projects go through the city’s Standard Plan Review program. That program covers new construction, alterations, and tenant buildouts for restaurants and bars. It is used for non-residential projects up to 150,000 square feet and new buildings up to 80 feet tall. Larger or more complex projects go through the Developer Services program.
Standard Plan Review requires an architect to prepare drawings that satisfy many separate code reviews. A restaurant project can trigger ten or more reviews, plus reviews from other departments such as Zoning, Landscape, and the Department of Transportation. Other permits often follow, including sewer, water, and driveway permits.
Other review paths:
- Easy or Express Permit: For minor repair and replace work with no drawings. Not for a restaurant buildout.
- Self-certification: A registered Illinois architect or structural engineer with city training can certify eligible projects, which usually shortens review time.
- Trade permits: Electrical, plumbing, and mechanical permits are issued separately.
Typical review windows in Chicago:
| Permit Type | Typical Review Time |
|---|---|
| Easy or Express permit | 1 to 5 business days |
| Standard Plan Review, first review | 15 to 30 business days |
| Tenant improvements | 15 to 45 business days |
| Large commercial projects | 30 to 90 business days |
| Trade permits | 5 to 15 business days |
Add time for revisions. Almost every set of plans comes back with comments.
Health department plan review
Before you get a food license, the Chicago Department of Public Health reviews your food establishment plans. You submit a scaled floor plan, your equipment specifications, and your menu.
Your menu matters more than owners expect. It determines your equipment, your refrigeration, your sink requirements, and in some cases your grease interceptor size. Changing your menu after plan approval can mean re-submitting.
Retail Food Establishment license
Any business that prepares, serves, stores, or sells food from a fixed location in Chicago needs a Retail Food Establishment license. The license is issued for two years and must be renewed before it expires. Licenses are not transferable, so every location needs its own, and buying an existing restaurant does not get you the previous owner’s license.
Liquor license
Start this early. Liquor licensing commonly runs 30 to 90 days or more, and includes inspections and background checks. It also depends on your location, since some areas restrict or prohibit new licenses.
Public way permits
Sidewalk cafes and anything else that uses public space require City Council approval, and that process can take 60 to 120 days. If a patio is part of your concept, start it at the very beginning.
Other approvals you may need
- Zoning approval or a change of use
- Sign permit
- Certificate of occupancy
- Fire department inspection
- Elevator or equipment permits, in some buildings
- Landmark approval, if the building is landmarked

Suburbs are different
Each suburb has its own building department, its own adopted codes, and its own review times. County health departments handle food plan review outside the city. Some villages are much faster than Chicago. Others require more local approvals. Ask your contractor what to expect in your specific village before you set an opening date.
Part 4: The Kitchen
The kitchen drives most of the cost and most of the code requirements.
Exhaust hood and fire suppression
Cooking equipment that produces grease-laden vapor needs a Type I hood with a fire suppression system. Type II hoods handle heat and steam only, such as over a dishwasher.
What this involves:
- The hood itself, sized for your cook line
- Ductwork routed to the roof, with required clearances
- An exhaust fan
- A wet chemical fire suppression system, tied to gas shutoff
- Inspection and certification
Makeup air is not optional. Every cubic foot of air the hood pulls out has to come back in. Without a makeup air unit, doors stick, the hood pulls poorly, and your heating bill soars. Makeup air is one of the most commonly underestimated items in a restaurant budget.
Grease interceptor
Kitchen wastewater carries fats, oils, and grease into the sewer, where it causes blockages. That is why grease interceptors are required.
Your plans need to show which fixtures drain through the interceptor, how it is sized, and where it sits. Sizing depends on your fixtures, your flow, and your menu. Larger operations and heavy fryer use generally need in-ground interceptors rather than small under-sink units. Getting this wrong is a common cause of plan review comments and delays.
Plan early: An in-ground interceptor can mean cutting the concrete slab. That decision belongs at the design stage, not after tile is down.
Plumbing
Restaurant plumbing is heavier than most owners expect:
- Three-compartment sink
- Separate hand sinks, placed where code requires
- Prep sinks
- Mop sink
- Floor drains and floor sinks
- Grease waste lines
- Dish machine connections
- Water heater sized for the dish machine and sinks
Gas and electrical
Confirm both before you design the cook line. Adding gas capacity means working with the utility, and lead times can be long. Electrical service upgrades mean a new panel or even a new service, which is expensive and slow.
Refrigeration
Walk-in coolers and freezers need floor space, electrical, condenser location, and sometimes a structural check. Remote condensers on the roof are common, and they need a path for lines.
Finishes that pass inspection
Kitchen surfaces must be smooth, durable, non-absorbent, and easy to clean. That covers floors, walls, ceilings, and even light fixtures. Commercial kitchen flooring costs more than retail flooring for a reason.
Layout
A good kitchen layout shortens steps, keeps raw and ready-to-eat food separated, and puts hand sinks where staff actually work. A kitchen consultant or a designer with restaurant experience pays for themselves. So does having your chef review the plan before it goes to the city.
Part 5: The Dining Room and Front of House
- Seating count affects restroom requirements, exit requirements, and sometimes your parking requirement.
- Accessibility applies to entrances, routes, seating, the bar, restrooms, and the service counter. At least five percent of dining seats must be accessible.
- Acoustics. Hard surfaces look good in photos and sound terrible in person. Plan for sound control early.
- Lighting. Layer it. Restaurants need different light for day and night.
- HVAC comfort. Diners near the door in January will complain. Plan vestibules and diffuser locations.
- Point of sale and technology. Run the data and power during rough-in, not after.
- Bar. Adds plumbing, refrigeration, drainage, ice, and millwork. One of the most expensive rooms per square foot.
- Patio. Adds permits, surfacing, lighting, heating, and often public way approval.
Part 6: The Timeline
Here is a realistic schedule for a Chicago restaurant buildout.
| Phase | Typical Duration | Notes |
|---|---|---|
| Site selection and lease | 1 to 3 months | Do the contractor walkthrough here |
| Design and engineering | 4 to 8 weeks | Menu and equipment list drive the drawings |
| Permit and health plan review | 2 to 4 months | Revisions add time |
| Construction | 10 to 16 weeks | Longer for conversions |
| Equipment install and startup | 2 to 3 weeks | Often overlaps with construction |
| Inspections and licenses | 2 to 4 weeks | Sequence matters |
| Staff training and soft open | 2 to 4 weeks | Overlaps with final inspections |
Total: 5 to 9 months from signed lease to opening, for most projects.
How to shorten it
- Start the liquor license and public way permits first. They have the longest outside timelines.
- Phase the permits. A demolition permit can often be pulled while the main design continues.
- Lock the menu early. Menu changes ripple into equipment, plumbing, and health review.
- Order long-lead items early. Hoods, walk-ins, and custom millwork can take months.
- Use experienced designers. Plans drawn by someone who knows Chicago restaurant reviews come back with fewer comments.
- Do not set a hard opening date until permits are issued. Announcing an opening date you cannot hit costs money in marketing, hiring, and credibility.
Part 7: Inspections and Opening Day
The last 30 days have the most moving parts. Inspections must happen in the right order, and each one can require a re-inspection.
Typical final sequence:
- Rough inspections during construction (framing, electrical, plumbing, mechanical)
- Hood and fire suppression test and certification
- Final trade inspections
- Fire department inspection
- Building final inspection
- Health department pre-opening inspection
- Certificate of occupancy
- Licenses issued
- Staff certifications in place
- Soft opening
Common reasons finals fail:
- Missing or incorrectly placed hand sinks
- Grab bars or restroom dimensions slightly off
- Fire suppression not tested and certified
- Missing backflow prevention certification
- Exit signs, emergency lighting, or panic hardware not installed
- Gaps that allow pests, or missing door sweeps
- Work that does not match the approved plans
The fix: Walk the space with your contractor two weeks before final, with the plans in hand, and check every item. Small corrections are cheap in week 10 and expensive in week 16.
Part 8: Hiring the Right Contractor
Ask these questions before you sign a construction contract:
- How many restaurant projects have you completed in Chicago or my village?
- Have you worked with my type of concept?
- Who handles permits and expediting?
- How do you coordinate with my kitchen equipment supplier?
- What is your schedule, and what are the milestones?
- How do you handle change orders?
- What is included, and what is excluded, in this bid?
- Who is the superintendent on my job, and are they on site daily?
- What happens if the city issues revision comments?
- Can I talk to three restaurant owners you built for?
Compare bids line by line, not by bottom-line price. A low bid usually means something was left out. Our guide on how to read a commercial construction bid covers what to compare.
Part 9: Restaurant Types and What Changes
Fast casual and quick service: Smaller kitchens, heavier point-of-sale and queue design, sometimes a drive-thru. Drive-thrus add site work, stacking lanes, and zoning review.
Coffee shops and cafes: Lighter cooking loads, but heavy water and electrical needs for espresso equipment. See our post on the Middle Eastern coffee shop boom.
Full-service restaurants: The most complex. Full kitchen, bar, larger dining room, more finishes.
Franchises: The brand supplies a prototype, but it still has to meet Chicago or village code. Prototypes rarely fit an existing space without changes. See our franchise construction page.
Ghost kitchens: All production, no dining room. Still need full kitchen systems, health review, and grease control.
Part 10: Common Mistakes
- Signing a lease before a contractor sees the space.
- Budgeting only for construction, not soft costs, equipment, and rent during buildout.
- Forgetting makeup air.
- Starting the liquor license late.
- Changing the menu after health plan approval.
- Skipping the contingency.
- Announcing an opening date too early.
- Using a contractor with no restaurant experience.
- Ordering equipment that does not fit the approved plan.
- Assuming a former restaurant space is ready to go.
Where Restaurants Are Being Built Right Now
Restaurant construction is driving a large share of retail development across the region. Block 59 in Naperville replaced a half-empty shopping center with a cluster of restaurants and an outdoor plaza. Asian dining is filling the Riverbrook center on North Aurora Road. Suburbs from Schaumburg to Aurora are adding restaurant pads to redeveloped sites.

Frequently Asked Questions
How long does it take to build a restaurant in Chicago?
Most restaurant buildouts take 5 to 9 months from signed lease to opening. Design takes 4 to 8 weeks, permits and health plan review take 2 to 4 months, and construction takes 10 to 16 weeks. Converting a non-restaurant space takes longer than taking over a former restaurant.
What permits do I need to open a restaurant in Chicago?
Most restaurants need a building permit through Standard Plan Review, separate electrical, plumbing, and mechanical permits, health department food plan review, a Retail Food Establishment license, a certificate of occupancy, and a sign permit. A liquor license and a public way permit for a sidewalk cafe are needed if they apply to your concept.
How much does it cost to build out a restaurant?
The cost depends mostly on the space. Taking over a former restaurant with a working kitchen is the cheapest option. Converting retail space costs much more, because gas, grease waste, exhaust, and electrical capacity have to be added. Get a bid from a general contractor on real drawings rather than relying on per-square-foot averages.
Is it cheaper to take over an old restaurant space?
Usually yes. A second-generation space often has the hood, grease interceptor, gas service, floor drains, and restrooms already in place, which can save months and a large part of the budget. Have a contractor check whether the existing systems still meet code and fit your menu.
What is makeup air and why does it matter?
Makeup air replaces the air your kitchen hood pulls out of the building. Without it, the hood cannot exhaust properly, doors can be hard to open, and heating costs rise. It is required and it is one of the most commonly missed items in early restaurant budgets.
Do I need a grease trap for my restaurant?
Almost certainly. Grease interceptors keep fats, oils, and grease out of the sewer. Size and type depend on your fixtures and your menu. Heavy fryer use often requires an in-ground interceptor, which may mean cutting the floor slab, so plan it during design.
When should I apply for my liquor license?
As early as possible. Liquor licensing commonly takes 30 to 90 days or more and includes inspections and background checks. Confirm that a license is even available at your address before you sign the lease.
Can I change my menu after plans are approved?
Changing your menu can change your equipment, refrigeration, sink, and grease requirements, which may mean resubmitting to the health department. Lock the menu before plans are submitted.
