Restaurant Space Buildout vs Existing Space: What to Negotiate With Your Landlord

The Quick Answer

An existing restaurant space with a functioning hood, walk-in cooler, grease trap, and compliant kitchen layout saves $80,000–$200,000 in buildout costs versus a raw commercial space — but only if the infrastructure matches your concept's needs. Always have a licensed kitchen contractor and mechanical engineer inspect an existing space before signing, because inheriting a hood system too small for your cooking equipment or a walk-in on its last legs is not a savings, it's a liability. If taking a raw space, your negotiating leverage for TI allowance is highest — landlords expect to contribute $30–$80/sq ft to attract a restaurant tenant to a non-restaurant space.

White Box vs Gray Shell: Understanding What You're Getting

Commercial space condition descriptions vary by landlord but generally fall into these categories: Gray shell (also called 'cold dark shell') — bare concrete floors, unfinished walls and ceiling, no HVAC, no plumbing beyond a main line, no electrical beyond a main panel. This is the most work and expense; budget $200–$350/sq ft in buildout costs. White box (also called 'vanilla shell') — finished walls and ceiling, HVAC system in place, electrical circuits distributed to the space, basic restrooms completed. Buildout cost: $100–$200/sq ft on top of restaurant-specific fit-out.

Existing restaurant space — prior tenant left infrastructure in place: hood, walk-in, grease trap, kitchen plumbing, and sometimes equipment. Buildout cost varies widely ($30–$150/sq ft) depending on what stays and what needs replacement. The critical question for an existing restaurant space: why did the previous restaurant close? If they closed due to poor management, you may have inherited a good space. If they closed due to location or market factors, you face the same headwinds. If they closed due to a health department issue, do a thorough environmental inspection before signing anything.

Negotiating Tenant Improvement (TI) Allowance

TI allowance — money your landlord contributes to your buildout in exchange for signing a longer lease — is the most significant financial concession available in a restaurant lease negotiation. Landlords offer TI because an improved, restaurant-ready space commands higher rent in the future and demonstrates commitment from a serious tenant. Standard TI allowance ranges: $20–$40/sq ft for a white box space, $40–$80/sq ft for a gray shell conversion to restaurant use, and $0–$20/sq ft for an existing restaurant space (less to improve).

Negotiation tactics: (1) Get competitive bids from two or three spaces and use them against each other. (2) Present a detailed buildout plan with contractor bids — landlords respond better to specific asks ('we need $120,000 TI to complete the kitchen and dining room') than vague negotiating ('we need help with buildout'). (3) Offer a slightly longer lease term in exchange for higher TI — a landlord might go from $45/sq ft to $65/sq ft TI if you agree to a 10-year initial term rather than 7. (4) Negotiate for TI to be paid in draws as construction milestones are reached, not as a lump sum after completion — this protects your cash flow during the buildout period.

Hood Systems Already in Place: Verify Before You Rely

An existing hood and fire suppression system is one of the most valuable pieces of infrastructure to inherit — but only if it's correctly sized and code compliant for your menu. Hood capacity is measured in CFM (cubic feet per minute of exhaust) and must match the BTU output and smoke/grease production of your cooking equipment. A hood sized for a sandwich shop's panini press will not meet code for a steakhouse's high-BTU broiler.

Before signing a lease that relies on an existing hood, hire a licensed kitchen ventilation contractor ($500–$1,500 for an inspection) to evaluate: hood size and CFM rating versus your planned equipment, condition of the grease duct and filters, fire suppression system status and certification date (Ansul systems require semi-annual inspection; an expired system means immediate cost), make-up air system adequacy, and local fire code compliance. A hood replacement in an existing space — if the existing one is inadequate — costs $15,000–$40,000 installed. If the landlord won't disclose the hood's inspection history, that's a red flag worth taking seriously before signing.

ADA Compliance: Your Responsibility, Your Cost

The Americans with Disabilities Act (ADA) requires that places of public accommodation — including restaurants — be accessible to people with disabilities. For a new restaurant lease, you are responsible for ensuring the space is ADA compliant, even if you're leasing an existing space. Common ADA issues in restaurant spaces: doorway width (minimum 36 inches for wheelchair access), accessible restrooms (turning radius, grab bars, sink height), accessible seating (at least 5% of tables must be accessible), ramp access if the floor level changes, and accessible path from parking to entrance.

ADA modifications in an existing space can run $5,000–$30,000 depending on what's needed. Have a certified ADA inspector evaluate the space before signing the lease ($500–$1,500), and try to negotiate that the landlord cover ADA compliance costs (they have a separate obligation under ADA Title III as the property owner). Document all ADA compliance work — in the event of an ADA complaint or lawsuit, proving you made good-faith compliance efforts significantly limits your liability. ADA lawsuit settlements average $25,000–$75,000; this is not an area to cut corners.

Getting the Right Inspections Before You Sign

Before signing any restaurant lease — new or existing space — commission three inspections that together will surface 90% of potential costly surprises: (1) Commercial kitchen contractor inspection ($500–$1,500): evaluates all existing kitchen infrastructure — hood, walk-in, grease trap, plumbing, electrical panel capacity. Confirms whether existing equipment can stay or must be replaced. (2) Mechanical and structural engineer review ($1,000–$2,500): assesses HVAC capacity, structural load capacity for walk-in and equipment, and identifies any building deficiencies that could delay your CO or require expensive remediation. (3) ADA accessibility consultant ($500–$1,500): identifies all non-compliant elements and estimates remediation costs.

Total inspection cost: $2,000–$5,500. This is the best money you'll spend before signing a lease that commits you to $500,000+ in total obligations over a 10-year term. Include an inspection contingency clause in any letter of intent: 'This offer is contingent upon satisfactory third-party inspections of kitchen infrastructure, HVAC, and ADA compliance, to be completed within 20 days of signing.' If the inspections reveal material issues, you have the right to renegotiate or walk away before you're legally committed.
