Quick Answer
Read a commercial lease as a connected business system, not as a list of isolated clauses. Before signing, answer five questions:
- What will occupancy actually cost? Rebuild the payment formula from base rent, operating expenses, taxes, insurance, utilities, percentage rent, and one-time charges.
- Can the business legally and practically operate in the space? Check permitted use, zoning responsibility, access, signage, parking, hours, exclusivity, and opening conditions.
- Who pays when the premises or building needs work? Match repair duties, capital costs, tenant improvements, delivery condition, casualty, and compliance obligations.
- Can the lease move with the business? Review assignment, subletting, change-of-control, lender, and franchise-transfer provisions.
- What is the downside if the plan changes? Trace the personal guarantee, default remedies, holdover, renewal, termination, and surrender language.
The decision is not whether one clause looks unusual. It is whether the complete lease fits the business plan, financing, and exit path.
For California leases, determine with counsel whether the tenant qualifies for SB 1103 protections. The statute adds specific notice, translation, and operating-cost rules for certain qualified commercial tenants; it is not a substitute for reviewing the full lease.
The Six Decisions to Make
| Decision | Read together | What you need before signing |
|---|---|---|
| Total occupancy cost | Rent, additional rent, CAM, taxes, insurance, utilities, audit rights | A year-by-year cost model tied to the lease definitions |
| Operating control | Use, exclusivity, access, signage, parking, compliance, relocation | Written confirmation that the intended operation is permitted |
| Build-out and opening | Delivery condition, plans, approvals, TI allowance, commencement | A responsibility and deadline matrix |
| Transferability | Assignment, sublease, change of control, franchise and lender terms | A path for a sale, refinance, or ownership change |
| Personal exposure | Guaranty, indemnity, insurance, default and remedies | A defined maximum downside reviewed by counsel |
| Continuity and exit | Renewal, holdover, casualty, condemnation, SNDA, surrender | Clear options if the location or business plan changes |
1. Rebuild the Occupancy Cost
Do not compare locations using base rent alone. Create a worksheet that maps every payment obligation to its formula, timing, supporting records, and dispute process.
Start with:
- base rent and each scheduled adjustment
- the definition of additional rent
- the tenant's share of operating expenses and how that share can change
- exclusions and inclusions in CAM or building operating costs
- management or administrative fees
- property tax and insurance pass-throughs
- utilities, after-hours services, and maintenance contracts
- percentage rent or other revenue-linked charges
- late fees, interest, security deposits, and restoration costs
For CAM, trace the defined terms through every exhibit. A cap can be less useful than it appears if major categories sit outside it. An audit right can be difficult to use if the lease gives the tenant little time to object or limits access to records. The CAM clause guide explains the questions to carry into a lease review.
The output should be a cost model with assumptions labeled, not a single rent number.
2. Confirm the Business Can Operate
A favorable rent does not solve a use restriction. Compare the permitted-use language with the current operation and plausible next steps: new products, delivery, classes, equipment, franchisor requirements, or a later buyer's use.
Review these provisions together:
- permitted and prohibited uses
- zoning, permits, licenses, and code compliance
- exclusive-use rights and their exceptions
- continuous-operation or opening requirements
- access hours, parking, loading, signage, and deliveries
- landlord relocation rights
- rules and regulations that the landlord may change
Do not treat a broker email or floor plan as a lease right. Put any essential operational promise in the signed document or an incorporated exhibit, with the remedy spelled out.
3. Fix the Build-Out and Commencement Sequence
The lease should connect delivery of the premises, construction responsibilities, approvals, and rent commencement. Build a simple sequence showing:
- the required delivery condition
- who prepares and approves plans
- who performs each category of work
- how the tenant-improvement allowance is documented and paid
- what happens if landlord work, permits, or delivery is delayed
- when possession, opening, and rent obligations begin
Check whether unused allowance is forfeited, credited, or recoverable and whether landlord-funded work is recaptured after an early termination or default. See the tenant improvement allowance guide for a clause-level checklist.
4. Protect Transfer and Financing Options
Assignment language matters even if no sale is planned today. A lease may treat a merger, equity transfer, franchise transfer, or change of control as an assignment. That can affect an acquisition, a refinance, or estate planning.
Identify:
- which events require consent
- the information and deadlines required for a consent request
- whether the landlord may impose conditions or recapture the space
- whether the original tenant and guarantor remain liable after a transfer
- whether transfers to affiliates, lenders, a franchisor, or a buyer receive different treatment
- whether subletting is governed by the same or different rules
If the location is material to an acquisition, align the lease consent process with the purchase agreement's closing conditions.
5. Define Personal Exposure and Default Risk
A personal guaranty can move lease risk outside the tenant entity. Read it with the default, acceleration, indemnity, attorneys' fees, insurance, and surrender provisions.
Ask counsel to map:
- the obligations covered by the guaranty
- any dollar, time, or event-based limit
- whether amendments or extensions expand the guaranty
- notice and cure rights before default remedies apply
- the treatment of casualty, condemnation, assignment, and surrender
- any continuing liability after the space is returned
Do not assume a lease termination ends the guaranty. The signed language controls. Use the personal guaranty guide to prepare the questions, then have real-estate counsel assess enforceability and remedies in the relevant jurisdiction.
6. Test Renewal, Disruption, and Exit
Calendar every notice deadline and state exactly how notice must be delivered. Then test the lease against three scenarios: the business outgrows the space, the site cannot operate after a casualty, or the landlord or its lender changes.
Review:
- renewal options and conditions that can defeat them
- holdover rent and other holdover consequences
- surrender and restoration duties
- casualty and condemnation allocation
- subordination, non-disturbance, and attornment provisions
- termination, assignment, and subletting paths
An SNDA is a separate agreement involving the landlord's lender. Its effect depends on the executed text and the financing structure; do not infer protection from the lease heading alone.
Documents to Collect Before Review
The lease rarely contains the whole commercial deal. Collect the proposal or letter of intent, every exhibit and addendum, site plan, work letter, guaranty, rules and regulations, operating-cost history, insurance requirements, and any franchisor or lender conditions. Record unresolved business facts separately from legal questions.
How Inkvex Fits the Review
An Inkvex commercial lease review is a $49 one-time lane with one credit and 12-month access. It quotes source clauses and assigns a 1-to-10 risk score. The Diligence Memorandum, Executive Deal Verdict, Cross-Reference Map, and Negotiation Points are standard paid-lane deliverables. Relevant market comparisons appear only when a verified applicable lease corpus is available for the uploaded document.
Use that output to organize a first-pass issue list and attorney handoff. It does not verify zoning, inspect the premises, calculate missing operating-cost data, or determine enforceability. The Negotiation Simulator is included only with Searcher Sub and Deal Pack.
Bottom Line
Do not sign until the economics, operating permissions, build-out sequence, transfer path, personal exposure, and exit mechanics agree with one another. If a critical business promise is not in the signed documents, treat it as unresolved.
