It should not be the last thing. A commercial lease can affect your cash flow, your ability to sell the business, your exposure to repair costs and, in some cases, your personal assets. Many of those consequences live outside the base-rent provision. So before signing, ask a better question than “Can I afford the rent?” Ask: **“What else am I agreeing to pay, guarantee or give up?”** [ schedule my consultation ](https://www.lumlawgroup.com/contact-us/) ## Table of Contents ## Start with the full occupancy cost A lease may involve more than base rent. Depending on the structure, the tenant may also pay a share of taxes, insurance, common-area maintenance and other operating expenses. For a business owner, the important task is to understand how those costs are calculated and whether the lease gives the landlord broad discretion to increase them. Do not assume that a “3% to 5% cap” is a universal rule. It is often a negotiation point, and the definition of controllable expenses matters just as much as the percentage. ## Personal guarantees deserve serious attention A personal guarantee can turn a business obligation into a personal exposure. Ask exactly what is guaranteed, how long the guarantee lasts and what happens if the business closes, sells, assigns the lease or stops operating. A negotiated “good guy” structure or a burn-off provision may be worth discussing, but neither should be treated as automatic. The actual language controls. ## Repairs can become a five-figure problem Who replaces the air-conditioning unit? Who pays for plumbing? What about structural work? What happens after years of wear and tear? The answer should come from the lease, not from assumptions about what a landlord“ normally” pays. California commercial leases can allocate repair and maintenance responsibilities by contract, subject to applicable law. That makes the allocation language critical. An illustrative scenario: a restaurant signs a five-year lease without examining the repair provisions. A major HVAC system fails. The tenant then discovers that its “maintenance” obligation was drafted broadly enough to create a costly dispute over replacement responsibility. The problem was not the HVAC unit. It was the lease language written five years earlier.

Can you sublet? Can the landlord withhold consent? Is consent subject to a reasonableness standard? Does the lease give the landlord a right to recapture the space? Those clauses can materially affect the value of a business when an owner wants to sell or restructure. ## The lease should match the business you expect to become One of the most useful negotiating questions is: **“Will this lease still work if my business changes?”** A narrow permitted-use clause, rigid signage restrictions, limited assignment rights or expensive restoration obligations can become problems later—even if the space is perfect today. A good commercial lease review is therefore not just document proofreading. It is business-risk planning. **What lease term would you negotiate hardest: operating expenses, personal guarantees, repair obligations or the right to exit?** ## The Bottom Line A commercial lease is more than a document that gives your business a place to operate. It can determine how much you really pay for the space, how much personal risk you carry, who pays when expensive equipment fails and how easily you can change direction later.
