A practical way to compare landlord delivery, reusable systems, demolition, approvals and opening risk before choosing a unit.
A finished unit is not automatically the cheaper choice, and a clean shell is not automatically the safer one. The better unit is the one whose verified condition fits the proposed operation with the fewest expensive assumptions.
A shell gives the design team fewer legacy partitions and finishes to work around, but the tenant may need to build nearly every service connection. An existing fit out may preserve washrooms, ceilings, lighting or mechanical systems, but only after the team confirms that they are permitted, serviceable and suitable for the new layout.
Compare both units from the same operating brief and the same evidence standard. The decision should show what the landlord delivers, what can truly remain, what must be removed, and which unknowns could still change the budget or opening date.
Key takeaways
• Define the delivered condition in writing; the labels shell and improved unit are too vague for pricing.
• Give existing work credit only after checking approval, capacity, condition and fit with the new operation.
• Compare total exposure, including demolition, investigations, landlord-controlled work and schedule risk.
Start with the operation instead of the empty room
Write down the staff count, peak customers, equipment, storage, deliveries, hours, cooking or process loads, privacy needs and target opening date. Then test each unit against that same brief. Otherwise one space may be priced as a basic refresh while the other is priced as a complete build out.
Confirm the proposed use and approval path before comparing finishes. A former restaurant is not automatically suitable for another restaurant, and an office layout may not support a clinic, classroom or showroom without changes to capacity, exits, ventilation or accessibility.

Define exactly what the landlord will deliver
For a shell, record the slab and wall condition, ceiling height, storefront, washrooms, electrical service, HVAC connection, plumbing stubs, gas, exhaust route, sprinkler and fire alarm coverage, telecommunications entry, loading access and any landlord-provided work. Note the location and capacity of each connection, not simply that it exists.
For an existing fit out, list every item the tenant expects to receive: partitions, doors, ceilings, lighting, millwork, washrooms, equipment and building services. State whether each item is included as is, warranted, tested, removed by the landlord or transferred without warranty.
Attach the delivery schedule to the lease documents and drawings. If the landlord promises additional power, a rooftop opening or a completed washroom, identify the design basis, approval responsibility, completion evidence and required date.
Audit an existing fit out before assigning savings
Tag each visible item as retain, modify, remove or investigate. Retain means it fits the new plan and can remain after review. Modify means the item has value but needs defined work. Remove includes demolition, disposal and making good. Investigate means no saving should be assigned yet.
Open accessible panels, inspect above ceilings where permitted, test equipment, photograph labels and compare the site with available approved drawings. Review maintenance records for HVAC and specialized equipment. Check for evidence of leaks, patching, abandoned wiring or undocumented alterations.
A ceiling may look reusable until the new room layout requires relocation of lights, diffusers, sprinklers and detectors. Existing millwork may save fabrication but force an inefficient customer path. Record both the retained value and the cost of adapting around it.
Price shell work as connected systems
A shell estimate should not be a list of finishes placed into an empty rectangle. Start with the path from the base building to each operating requirement: service capacity, distribution, controls, drainage, ventilation, fire protection, data and equipment support.
For each system, note the source, available capacity, connection location, tenant work, landlord or base-building work, professional design, permit review, testing and shutdown requirements. A plumbing stub at the rear of a unit has limited value if the layout needs drainage at the storefront and slab cutting is restricted.
Release design and long-lead equipment only after the critical interfaces are confirmed. A clean shell reduces demolition surprises, but it can carry more dependencies on utility releases, landlord contractors and common-property access.
Compare six decision areas on the same page
Layout fit: Can the operation work without keeping awkward rooms or placing expensive services far from their connections?
Systems: Which capacities and routes are verified, and which require design, testing or landlord confirmation?
Removal and correction: What must be demolished, disposed of, remediated or brought into the approved scope before new work begins?
Approvals: Does the existing work match available records, and does the proposed operation change the permit path?
Schedule: Which investigations, shutdowns, landlord decisions and long-lead items sit on the critical path?
Residual risk: Which unknowns remain after review, who owns them, and what decision date prevents them from becoming a late change?
Model total exposure instead of one construction number
Build the comparison from the same categories: investigations, design and permits, landlord work, tenant construction, equipment, demolition, temporary services, contingency and carrying costs before opening. Show confirmed amounts separately from allowances and unresolved risks.
An existing unit may have a lower direct construction estimate but a longer investigation period and more demolition uncertainty. A shell may cost more to complete but offer clearer quantities and fewer constraints on the operating layout. The comparison should make those differences visible rather than forcing both into one cost-per-square-foot number.
Include schedule exposure in the decision. Rent-free periods, fixturing periods and possession dates matter only when they align with access, design release, permit timing and landlord completion. Have the leasing lawyer and broker address these commercial terms in the lease.
Use a two stage site review before committing
Stage one is a screening visit. Photograph the unit, electrical and mechanical rooms where access is available, washrooms, roof or shaft interfaces, loading route and neighbouring occupancies. Mark obvious conflicts with the operating brief and identify records to request.
Stage two is a focused technical review for the short-listed unit. Bring the appropriate designer, contractor and engineers for the actual risk. Arrange testing or destructive investigation only with permission. Convert each finding into a drawing note, scope item, lease condition or recorded risk.
Set a decision deadline for every critical unknown. If power capacity, exhaust routing or landlord approval cannot be confirmed by that date, compare an alternate design or another unit instead of carrying an undefined promise into construction.

Frequently asked questions
Is a second generation restaurant usually cheaper than a shell restaurant space?
Only when the expensive existing elements are approved, serviceable and compatible with the new menu, equipment and seating plan. Verify the hood and make-up air, gas and electrical capacity, drainage, fire protection, washrooms and equipment condition. Include removal and adaptation costs before assigning a saving.
Does an as is clause mean the previous tenant work can stay?
No. As is describes a commercial handover condition; it does not prove that every alteration was approved or suitable for the new use. Compare the site with available records and have the relevant professionals identify what may remain, what needs correction and what still requires investigation.
What unresolved issue should stop a tenant from signing?
A unit deserves a pause when a business-critical condition depends on unverified capacity, an unavailable route or work controlled by the landlord with no defined commitment. Examples include electrical service, exhaust routing, drainage, exits or permission to alter common property. Resolve it, create an enforceable lease condition or choose another unit.
Compare the units with evidence
Y&Y Construction can help organize site information, coordinate focused design and technical reviews, and turn the findings into comparable construction scopes. Bring the operating brief, leasing plans, landlord delivery schedule and available records so both units can be tested against the same assumptions.
