Most restaurant delays don't start on the job site. They start weeks earlier, in a lease that got signed before anyone checked whether the space could actually support a commercial kitchen. If you're planning a build-out in Denver, the sequence below — lease diligence, permits, health department review, patio work, and the money — is the order things actually need to happen in, not the order most people find out about them.
This applies whether you're opening a first location or your fifth: every space is a different shell, in a different building, with a different permit history, and none of that shows up on a listing sheet. It shows up when a contractor walks the space before you sign.
Before You Sign: What a GC Checks in Your LOI and Lease
Bring a contractor into the conversation before you sign a letter of intent, not after. There are things a lease can lock in — or lock out — that no amount of good construction can fix later:
- Use clause. Does the lease actually permit "restaurant" or "food service" use, including any specifics your concept needs (full kitchen, hood ventilation, alcohol service)? A restrictive use clause can block your concept entirely.
- Delivery condition. Is the landlord handing you a bare "vanilla" shell, a "gray shell" with some base building systems roughed in, or a second-generation restaurant space with an existing kitchen? This single fact swings scope, cost, and timeline more than almost anything else.
- Existing infrastructure. Grease trap or grease interceptor, kitchen exhaust hood and make-up air system, and gas service capacity are expensive to add from scratch. If the space was never a restaurant, assume none of it exists until proven otherwise.
- Utility capacity. Electrical service size, gas load, and water/sewer capacity for a grease interceptor need to match your kitchen equipment load — not just the building's general capacity.
- Landlord's TI allowance and disbursement terms. How much, and — critically — when does the landlord actually pay it? (More on this below.)
- Construction access and hours. Loading dock access, freight elevator availability, and any landlord-imposed construction hour restrictions affect your schedule before a single permit is filed.
- Prior use and permit history. A space that was previously a restaurant with an intact hood and grease interceptor is a fundamentally different project than a space that was last a retail storefront, even if the square footage is identical. Ask the landlord for the prior tenant's use and, if possible, their as-built drawings.
- Signage and exterior approval rights. Whether you need landlord sign-off — separate from the city's own sign permit — for exterior signage, awnings, or a patio structure often lives in the lease, not in city code.
A GC who reviews the lease alongside your broker or attorney — before signing — catches problems while they're still negotiable. After signing, they're just problems.
Permits and Health Department Sequencing
A Denver restaurant build-out runs on two tracks that have to be coordinated, not sequential:
Building/TI permit. Construction drawings for the space go through Community Planning and Development for the tenant-improvement building permit — structural, mechanical, electrical, plumbing.
Health department plan review and licensing. In parallel, the Denver Department of Public Health & Environment reviews plans for any new or remodeled food facility — kitchen layout, sinks, refrigeration, and ventilation — before the space can open. That plan review has to be coordinated with the same construction drawings going through building permitting, because a kitchen layout the health department won't approve is a kitchen layout you shouldn't be building. Once compliant, the business obtains a Retail Food Establishment license through the Department of Excise and Licenses. DDPHE's own compliance page notes that, once operating, full-service restaurants are inspected twice yearly and limited-service establishments on a longer cycle — a sign of how seriously plan review is treated on the front end.
Liquor licensing, if you're serving alcohol. This is a separate track through Denver's Excise and Licenses liquor division, typically a Hotel and Restaurant license for a full-service concept, applied for through the retail establishment liquor permit process. It runs independently of the building and health tracks, which is exactly why it needs to start early rather than after construction wraps.
A GC who is commercially licensed and insured to pull Denver TI permits — and who has coordinated a kitchen build against DDPHE plan review before — is the difference between these three tracks running in parallel and running into each other. Missing that coordination is one of the most common reasons a build-out that looked simple on paper ends up waiting on a single re-review that could have been avoided at the drawing stage.
Patio and Outdoor Additions
If your concept includes a patio, it's effectively a second project layered onto the first: outdoor construction, potential public right-of-way encroachment if you're extending toward a sidewalk or street, and — if you're serving alcohol outside — a separate premises modification on your liquor license to cover the outdoor footprint. This is specialized enough that we run it through our dedicated patio and outdoor build practice, The Restaurant Patio, rather than treating it as an afterthought bolted onto the interior build-out.
Tenant-Improvement Dollars: What They Cover and What They Don't
A landlord's TI allowance is a negotiated contribution toward buildout, but two things about it matter more than the headline number: what it's calculated against, and when it pays out. TI allowances are typically disbursed on completion milestones — often tied to a certificate of occupancy — not up front, which means you're financing the build before reimbursement arrives. And a TI allowance sized for a generic office or retail tenant rarely anticipates restaurant-specific costs: hood systems, grease interceptors, upgraded gas and electrical service, and health-department-driven finishes (specific wall, floor, and ceiling materials) are the items that most often exceed what a landlord assumed the space would need.
There's also a sequencing trap worth naming directly: if disbursement is tied to a certificate of occupancy, but your buildout requires infrastructure work before the health department will even approve your kitchen layout for permit, you can end up needing capital to fund the early, expensive phase of the project before the milestone that unlocks the TI allowance is even reachable. Getting a real construction estimate — informed by the delivery condition and infrastructure questions from your lease review — before you finalize the TI number in your lease is what keeps that gap from becoming a mid-project surprise instead of a line item you negotiated for up front.
Schedule Reality: What Actually Takes the Time
The single biggest schedule variable isn't the size of the space — it's how "vanilla" the shell actually is. A second-generation restaurant space with an existing hood, grease trap, and adequate gas and electrical service can move through construction fast, because the expensive infrastructure is already there. A raw shell that needs all of that built from scratch takes materially longer, because the sequence of utility work, rough-in, and inspections has more steps and more dependencies on outside utility providers.
The other major variable is whether the building-permit track and the health-department track are running in parallel or bottlenecking each other. If your construction drawings and your health department kitchen layout aren't coordinated from day one, you can end up building to a plan that health review later rejects — which means rework, not just delay. A design-build GC who manages both tracks simultaneously, with one team accountable for keeping them aligned, is what prevents that scenario rather than discovering it mid-construction.
Bring Us In Before You Sign
The best time to involve a contractor is during lease negotiation, not after the ink is dry — that's when a delivery-condition or infrastructure problem is still something you can negotiate around instead of something you have to build around.
