The key decision
A former restaurant can reduce construction scope only when its documented approvals, equipment condition and utility capacity match the next operation. Verify those three things before treating existing infrastructure as savings.
Start with the business you intend to operate
A space can look almost ready while being poorly suited to the next restaurant. The useful question is not whether someone cooked there before. It is whether the proposed menu, production volume, service model and hours fit the infrastructure you can actually keep. A sandwich shop and a busy fried-food concept may share a dining-room footprint while demanding very different kitchen arrangements.
Write a one-page operating brief before the site visit. Include food preparation methods, major equipment, peak service pattern, takeout volume, dishwashing approach, deliveries and anticipated seating. Separate opening-day needs from possible later menu additions. Ask the design team to assess both, because a cheap initial layout may make the next change unusually disruptive. This brief helps a contractor identify investigations; it does not establish regulatory approval or the adequacy of a system hidden above the ceiling.
Request records before accepting the existing layout
Request the latest building finals, approved kitchen plans, health inspection reports, unresolved correction notices, hood service records and grease-device maintenance logs. Compare them with what is physically present. A prior satisfactory inspection concerns the operation inspected at that time; it cannot answer whether a new fryer, relocated sink or different ownership has been reviewed. Ask the seller to identify alterations completed after the last approved plan.
Santa Clara County offers a facility evaluation before purchase and says food operating permits do not transfer to new owners. Significant menu or equipment changes can instead require plan review. Confirm the actual route for your address. Resolve open findings with the responsible agency, rather than treating a landlord's statement that the last tenant was open as proof that your concept can open. Missing records mean investigation is needed; they do not establish that the previous operator acted unlawfully.

Classify inherited equipment instead of pricing it all as free
Create an asset list with four possible decisions: retain after verification, service before use, replace, or remove. Record ownership separately. A hood, refrigerator or water heater can be present without belonging to the landlord, operating correctly or meeting the new equipment schedule. Photographs help identify items, but condition should be assessed by the appropriate specialist with access and authorization to perform the necessary checks.
Request service information, model identification and observations of operation where practical. For refrigeration, discuss condition and suitability with the vendor; for ventilation, ask the mechanical designer about the complete system; for plumbing, investigate the route and documented grease-management arrangement. Include removal and disposal in a replacement allowance. A replacement asset can also require access work, finishes and reconnecting neighboring systems. The apparent value of inherited equipment disappears quickly if the budget includes only its purchase price and overlooks everything required to exchange it.
Look beyond the kitchen walls
Restaurant systems often depend on areas outside the leased suite. Trace the proposed exhaust path, rooftop equipment location, utility access, grease-service access and delivery route with the property team. Establish who controls each area and whether work would affect other tenants. A roof opening or service interruption may need a different permission process than interior paint, even when the restaurant pays for it.
Review arrival and dining access at the same time. Federal ADA guidance treats accessible routes, dining areas and service counters as part of customer access; a pleasant new dining room does not resolve a difficult entrance. Have the architect or accessibility specialist evaluate the actual alteration under applicable federal and California requirements. At this stage, the goal is a clear list of physical constraints and investigation tasks. Do not turn a rough walkthrough into a statement that the premises are fully compliant.

Put lease assumptions into a responsibility schedule
The construction team can identify a damaged component and price a repair, but it cannot decide which party owes the money under the lease. Ask the landlord and your lease adviser to settle the business allocation. Use a schedule listing the item, current evidence, required action, paying party, approving party and completion dependency. Keep this separate from a general promise that the premises will be delivered ready for occupancy.
Discuss access for inspections before commitment, responsibility for existing defects, ownership of retained equipment, roof work, utility upgrades and the relationship between construction delays and the business opening target. A tenant-improvement allowance also needs a defined reimbursement process; it should not be assumed to equal cash available on the first workday. The point of the schedule is to expose conflicting assumptions while options remain open. A contractor's estimate and the landlord's proposal should describe the same starting condition.
Verify gas, electricity and the grease path
Ask the electrical designer to compare the proposed equipment loads with the existing service, distribution and usable voltage and phase. Ask the gas designer or qualified contractor to review the appliance demand, available delivery conditions and existing distribution, then establish whether utility review is needed. A meter label, empty breaker position or unused gas stub is not a capacity assessment. Photograph accessible labels for the specialists; do not open equipment or test connections yourself.
PG&E has a project process for new or changed gas and electric service; at some addresses a municipal utility is the relevant provider. Identify the serving utility and property-authorized applicant early. Record whether feasibility relies on a service upgrade, what information the utility still needs, and whether work outside the suite could interrupt neighboring tenants. Price the enabling work separately from connecting individual appliances.
Ask the sewer authority about reuse and fees
Locate the grease trap or interceptor, establish which fixtures drain to it, and request its approved plans, cleaning history, condition findings and service access arrangement. FOG means fats, oils and grease. San José's FOG program checks maintenance documentation and operating practices; its FAQ states that the program itself has no permits or fees. Other sewer authorities may use different approval routes. Ask the authority whether the proposed cooking and washing load can use the existing device and whether unresolved corrections affect the next operation.
Separate grease-program questions from sewer capacity charges. San José's sewer-fee information sheet distinguishes one-time capacity charges from annual use charges and discusses credits for prior uses. That sheet is dated 2019, so obtain a current address-specific determination instead of using its example rates. Ask whether records substantiate any prior capacity payment, whether the new use changes the calculation, and who carries the cost under the lease. An existing drain proves neither a fee credit nor adequate capacity.

Use missing information to negotiate the next investigation
Be precise when reporting uncertainty to the property team. Instead of saying the plumbing looks questionable, identify the missing record, inaccessible section or unanswered capacity question and the inspection needed to resolve it. Ask for access to that investigation before the business relies on the asset. This creates a concrete request the landlord can consider and a defined task a specialist can price.
Also separate condition from remaining usefulness. A serviceable piece of equipment may have limited value if the operator expects to replace the entire line soon. Conversely, an older item may reasonably serve an opening phase if its condition, suitability and maintenance plan are confirmed. Put those assumptions into the retained-asset register. That makes the feasibility decision traceable and avoids assigning the same supposed savings to several different budget lines.
Set a practical go-or-revise decision
End due diligence with a written decision, not a collection of photographs. Identify the version of the menu and layout assessed, the records reviewed, limitations of access, specialist findings and outstanding questions. Assign each unanswered question to a person and a date. Separate issues that can be carried as a priced allowance from issues that could make the use or schedule infeasible.
Bring the operator, designer, contractor and property representative together to reconcile the list. Decide which layout changes preserve existing infrastructure, which replacements are justified and which assumptions need agency clarification. If the proposal changes materially after that meeting, update the feasibility assessment. This is especially important when a late menu idea adds a new cooking process. The next useful step is a defined design and investigation package with a budget range tied to assumptions, followed by approval-based construction planning.

| Approved plans and final records | Whether the visible layout matches documented work | Assign records research and agency clarification before treating it as reusable |
| Equipment identity and condition findings | Retain, service, replace or remove each asset | Carry explicit investigation or replacement allowance |
| Roof and utility access agreement | Whether required work can occur outside the suite | Resolve property permission and schedule dependencies |
| Menu and equipment schedule | Whether the concept matches the inherited kitchen | Revise the concept or evaluate new infrastructure |
| Gas/electric design and utility response | Whether the selected menu fits available service | Investigate upgrades before relying on inherited connections |
| Grease records, sewer review and prior fee evidence | Whether drainage can be retained and credits apply | Obtain address-specific answers; do not invent a universal FOG permit |

Common questions
Does an existing health permit transfer the old layout to our new concept?
Do not assume it does. Ownership, menu, equipment and construction changes can follow different local processes. Ask the county department to identify the review required for the proposed operation and retain the written response.
Should we keep every working piece of equipment?
Keep equipment that fits the menu, layout, condition and maintenance plan. A functioning unit can still consume valuable space or force an awkward workflow; compare the full cost and disruption of retaining it with a coordinated replacement.
