A commercial lease is a 30 to 60 page document that controls almost every economic and operational dimension of your tenancy for years. Most tenants read it once at signing and never again — which is why they miss the levers that matter when renewal approaches. Reading your lease productively means knowing which 15 to 25 standard clauses to extract into a structured abstract, knowing what each clause typically means in the Arizona commercial market, and knowing where landlords commonly write terms that look benign but compound into real costs over years. This guide walks through the standard clauses tenants should be able to find, summarize, and discuss with their broker and counsel before any renegotiation conversation begins.
Different lease forms organize content differently — full-service-gross leases look different from triple-net leases; institutional landlord forms differ from local-owner forms; the AIR forms used widely in California look different from the BOMA forms common in Phoenix office or the various industrial forms. But almost every commercial lease covers the same underlying terms. Find them in your lease in whatever order they appear:
1. Parties. Landlord entity name + tenant entity name. Look for any ambiguity about which entity is actually the landlord (sometimes a property owner holds title and a separate management company is named as landlord — affects who you negotiate with).
2. Premises. The exact square footage + suite or unit description + any common-area or storage components included. Watch for "approximate" or "rentable square footage" language — rentable typically inflates the usable footprint by a load factor (often 10-18% in office buildings).
3. Term. Commencement date + expiration date. Look for any rent commencement that differs from possession commencement (common — tenants get the space first, rent starts later).
4. Base rent and escalations. Annual rent schedule + how it escalates. Common Phoenix patterns: fixed annual percentage (2-4%); CPI-linked with a cap and floor; fixed dollar step-ups; or some combination. Track the actual dollars by year for the full term and any renewal period.
5. Operating expense / CAM pass-through structure. Whether your lease is gross, modified gross, gross stop, or triple net (NNN). What expense categories are passed through. What's excluded from the pool. What caps (if any) apply to year-over-year increases. What's your pro-rata share (typically your square footage divided by the building's leasable square footage — but the methodology can vary). What audit rights you have.
6. Tax and insurance pass-through. Often separate from CAM/OpEx. May have separate cap structures or methodologies.
7. Use clause. What the tenant is permitted to use the space for. Watch for overly narrow use clauses that limit your flexibility to evolve your business or to sublet/assign to a different user.
8. Exclusive use (retail-specific) or non-compete restrictions. In retail centers, the lease often includes either exclusivity protections for the tenant (no other tenant in the center can sell competing goods) or restrictions on the tenant's use.
9. Renewal options. How many renewal periods + length of each + notice requirements + the rent formula for each renewal. The rent formula matters enormously — "fair market value" with detailed appraisal process behaves differently than "fair market value" with no process specified.
10. Tenant-improvement (TI) allowance. Dollar amount the landlord contributes to build-out + how it's delivered (turnkey vs reimbursement) + what it can be used for + what happens if not fully used.
11. Assignment and subletting. Tenant's right to transfer all or part of the lease + what landlord consent requires + any conditions or profit-share. Critical for tenants whose business may evolve.
12. Default and remedies. What constitutes tenant default + cure periods + landlord remedies + tenant protections.
13. Holdover. What happens if tenant stays past expiration without a new lease. Holdover rent commonly jumps to 1.5x to 2x base rent and tenant may be liable for landlord's consequential damages.
14. Termination rights. Any early-termination right (often with a termination fee) + casualty / condemnation termination + any contraction or expansion options.
15. Audit rights. Tenant's right to audit landlord's OpEx pass-through calculation + the time window + the cost-allocation rules + the dispute-resolution process if audit finds material discrepancies.
16. Personal guarantees. Whether any individual (not just the tenant entity) personally guarantees the lease + the scope of the guarantee + any burn-down provisions that reduce the guarantee over time.
17. Security deposit. Cash amount + letter-of-credit alternatives + return conditions + landlord's right to draw + what the landlord can use it for.
18. Insurance requirements. Coverage types and limits required + additional insured requirements + waiver of subrogation provisions.
19. Maintenance and repair allocation. Who repairs what (landlord vs tenant). Common in industrial: tenant maintains everything inside the four walls; landlord maintains roof + structure + parking lot. Specifics vary.
20. Alterations. Tenant's right to modify the space + landlord consent requirements + restoration obligations at lease end.
21. Estoppel and SNDA (Subordination Non-Disturbance Agreement). Landlord's right to require tenant to sign estoppels for lender purposes + the SNDA that protects tenant if landlord's lender forecloses.
22. Notices. Where notices must be sent + how (certified mail, email, etc.) + when deemed received. Critical because missing a notice deadline can void protections.
23. Force majeure. What events excuse performance + for how long.
24. Mutual / unilateral provisions. Many leases include provisions that look mutual but only benefit one party — review carefully.
25. Governing law and jurisdiction. Which state's law governs + where disputes are resolved.
Pull each clause into a structured abstract (a single Word or Google doc, one or two pages). For each clause, write three things:
This abstract becomes the working document of your renegotiation. It's also the input we use when AI-assisted abstraction is part of our workflow — every AI-produced abstract is reviewed against the tenant's actual lease before any output reaches the tenant.
Three things tenants commonly miss when reading their own lease:
Compound escalations. A 3% annual escalator over a 10-year term compounds to 30%+ on year-10 rent versus year-1 rent. Tenants who anchor on year-1 rent miss this.
OpEx exclusions and inclusions. Most leases say "OpEx excludes the following" and then list 15-25 specific items. Tenants who don't read the exclusion list often pay for things that shouldn't have been billed (capital expenditures, owner overhead, leasing commissions, etc.). Deep treatment in Operating Expense Audits.
Renewal-rent formulas with no process. A lease that says "renewal at fair market value" without specifying the appraisal process or the comparable-set methodology gives the landlord significant unilateral leverage. Tenants who didn't catch this at original signing find out at renewal time.
Bring it to your broker (us, if we're a fit) and your counsel. Use it as the working document of the renegotiation strategy session (described in the main guide step 7). The abstract should be live — updated as new market data and landlord positions arrive — through the negotiation rounds.
Q: My lease is 60 pages. Where do I start? A: Start with the table of contents. Find the rent provisions, the OpEx / CAM provisions, the renewal options, the term, and the termination provisions. Those five sections control most of the economics. Once you've found those, work outward.
Q: Should I read it myself or hire someone? A: Both. You should read it once to understand it; your broker should review it as part of the renegotiation engagement; your counsel should review it for legal interpretation. The abstraction work — pulling the clauses into a structured summary — is something a broker does as part of the renegotiation engagement; it doesn't require you to do it yourself, though doing the first pass yourself improves your fluency in the conversation.
Q: My landlord said they "don't typically negotiate" the lease terms. Is that true? A: It's true that some institutional landlords have standardized lease forms they prefer not to modify. But almost every term in a commercial lease is negotiable; "we don't negotiate" usually means "we prefer not to negotiate" — which changes when leverage shifts.
