What to Check Before Signing a Commercial Lease

A promising storefront can become an expensive problem long before construction begins. The location may have the traffic you want and rent that fits the pro forma, but knowing what to check before signing a commercial lease can determine whether your business opens on schedule, requires costly redesign, or cannot operate there at all.

For a restaurant, liquor store, retail shop, office, or wellness concept, the lease should be evaluated alongside the physical space. A commercial tenant improvement is not just a cosmetic project. It has to support your operations, comply with local requirements, and fit the lease timeline and budget.

What to Check Before Signing a Commercial Lease

Confirm the permitted use before relying on the address

Do not assume a previous tenant’s use makes your intended use acceptable. Zoning, use restrictions, parking requirements, occupancy classifications, and local licensing rules can all affect whether your business is permitted at a particular address.

This is especially important when the new use changes the demands placed on the space. A former retail suite may not be approved for a restaurant with commercial cooking equipment. A standard office location may not be practical for a wellness facility that needs plumbing, showers, sound control, or specialized electrical service. A liquor store can face use-specific distance requirements and licensing considerations that do not apply to other retail tenants.

Start with the municipality’s zoning and land-use rules, then review the lease’s permitted-use language. The clause should be broad enough to cover your actual business model, including reasonable future additions to products or services. If your approval, licensing, or financing is still pending, consider whether the lease should include a contingency that allows you to exit if those approvals cannot be obtained.

Assess the space as it exists, not as it appears

A clean, vacant suite can hide constraints that are expensive to correct. Before signing, have the space reviewed for its current condition and its ability to support your plan. Square footage alone does not tell you whether the layout works for customer flow, equipment, storage, staff circulation, or required accessibility clearances.

Look closely at the electrical service, HVAC capacity, plumbing locations, water and sewer connections, gas availability, ceiling height, roof penetrations, storefront condition, and fire protection systems. Ask where utility meters are located and whether the existing service has capacity for your equipment. A salon, bakery, restaurant, or medical-adjacent wellness use may need far more electrical, plumbing, ventilation, or hot-water capacity than the prior occupant did.

Also inspect the parts of the property that are not inside the suite. Grease exhaust routes, rooftop units, trash access, loading areas, outdoor seating, signage locations, and parking can all shape the project. A landlord may be willing to approve an improvement in principle but unwilling to permit roof work, new exterior penetrations, or changes to a shared utility system. That distinction matters.

Price the Buildout Before You Commit

The monthly rent is only one part of the occupancy cost. The condition of the space and the work required to make it operational often have a larger effect on the first-year budget than expected.

A realistic pre-lease estimate should account for demolition, framing, finishes, mechanical and electrical work, plumbing, fire alarm and sprinkler modifications, permits, design, engineering, fixtures, equipment installation, and contingency. It should also account for work outside the suite when required, such as utility upgrades, exterior accessibility improvements, grease interceptor work, or modifications to a building fire protection system.

Tenant improvement allowances can be useful, but the number in the lease is not the same as a complete buildout budget. Review what the allowance covers, when it is paid, whether it requires landlord approval, and whether it can be used for soft costs such as design and permitting. Some allowances are reimbursed only after construction is complete, which creates a cash-flow requirement during the project.

For second-generation spaces, do not assume existing improvements are usable just because they are present. An old hood system, restroom, electrical panel, or HVAC unit may need repair, replacement, or code-driven upgrades once renovation work begins. A thorough site review before lease execution gives you leverage to negotiate a larger allowance, free rent during construction, landlord-performed base-building work, or a lower starting rent.

Understand code upgrades triggered by your project

Commercial renovation work is evaluated under current codes, not the standards in place when the building was first built. The scope of your improvements, the change in occupancy, and the condition of existing systems can trigger requirements that were not visible during the initial walkthrough.

Common examples include accessibility upgrades, exit and egress improvements, emergency lighting, restroom changes, sprinkler or fire alarm modifications, ventilation requirements, and energy-code upgrades. The extent of these requirements depends on the jurisdiction, existing conditions, and proposed use.

In Maryland, permitting and inspection expectations can vary by county and municipality. A location in Baltimore County may involve a different review path or local requirement than a similar suite in Montgomery County or Anne Arundel County. Early input from a commercial design-build team helps identify issues while the lease is still negotiable rather than after drawings are underway.

Read the Lease for Construction Rights and Timing

A lease can authorize you to occupy a space without giving you enough practical control to build out the business. Review the tenant improvement and alteration sections closely. They should explain which work requires landlord approval, what plans must be submitted, who pays for reviews, what insurance is required, and what happens to improvements at the end of the term.

Pay particular attention to approval timelines. If the landlord has broad discretion or no deadline to respond to drawings, material selections, signage plans, or contractor information, the opening schedule can slip before permits are even submitted. The lease should also address access before the rent commencement date. You may need early access for field measurements, design coordination, utility work, permitting inspections, and construction.

Construction hours, delivery restrictions, building rules, required contractors, elevator access, and noise limitations are equally relevant in multi-tenant properties. A project that can only receive deliveries during narrow windows or complete noisy work after business hours may cost more and take longer.

Match the lease term to your investment

A substantial buildout should not be supported by a short or uncertain lease term. If you are investing heavily in plumbing, kitchens, specialized finishes, equipment infrastructure, or a branded customer environment, calculate whether the initial term and renewal options give you enough time to recover that investment.

Review renewal rights, rent escalations, common area maintenance charges, property tax pass-throughs, insurance obligations, and utility responsibility. Ask for historical common area maintenance figures where available, not just an estimate. A lower base rent can be less attractive if operating expenses rise unpredictably or if major system repairs are pushed to the tenant through lease language.

Exclusivity provisions may also matter. A food operator may not want the landlord to lease the neighboring space to a direct competitor. Conversely, make sure a restrictive use clause does not prevent you from adding a complementary product line or service later.

Verify the Opening Schedule Against Real Milestones

Many business plans use an optimistic opening date based on signing the lease, ordering equipment, and starting construction immediately. In practice, the path includes lease negotiation, site investigation, design, landlord review, permit submission, plan review comments, revisions, construction, inspections, and final approvals.

The schedule depends on the project scope and jurisdiction. A modest office refresh may move quickly. A restaurant, bakery, liquor store, or specialized service environment with mechanical upgrades and licensing requirements will need more lead time. Equipment lead times can also control the opening date, particularly for HVAC equipment, electrical gear, custom millwork, refrigeration, kitchen equipment, and specialty fixtures.

Build a schedule that identifies the long-lead decisions first. Then negotiate rent commencement, free-rent periods, and any delivery obligations around a realistic construction timeline. If your business depends on a seasonal opening, franchise deadline, or the expiration of another lease, leave room for permitting and inspection variables rather than treating them as exceptions.

Document Existing Conditions and Landlord Commitments

Before execution, document the suite’s condition with photographs and written notes. Identify who is responsible for repairing existing defects, replacing failing equipment, addressing leaks, and bringing base-building systems to an agreed condition. Verbal assurances about a roof repair, electrical upgrade, or HVAC replacement are difficult to enforce later.

Landlord work should be defined with the same clarity expected in a construction scope: what will be done, who will do it, when it will be complete, and what standard it must meet. If your project depends on that work, include a remedy if it is delayed or incomplete.

Signing a lease is often the moment a business owner feels committed to opening. It should also be the moment to slow down, test the assumptions behind the location, and make sure the space can support the business you intend to run. Early construction and code review can turn lease negotiations into a practical risk-management step, protecting both your budget and the date you put on the calendar.
