A fixturing period in a commercial lease is a window of time, usually 30 to 90 days, during which a tenant can enter a newly leased space to install fixtures, complete a build-out, and prepare to open for business before the rent clock starts. Base rent is almost always waived during this window, but the tenant still pays certain operating costs and must carry insurance. The clock begins when the landlord formally delivers possession, and it ends on the date set in the lease or the day the tenant opens for business, whichever comes first.
Your Legal Status During Fixturing
The fixturing period sits between two milestones: the day the landlord delivers the space and the day the lease term formally starts. You have physical possession, but legally you’re occupying under a license rather than a full tenancy. That distinction matters. A license gives the landlord more flexibility to manage the arrangement, and you don’t yet hold the same legal interest in the property that you will once the lease term begins. If a dispute arises during fixturing, courts in most jurisdictions treat a licensee differently from a tenant, particularly when it comes to remedies for removal or access revocation.
The lease spells out what you can and cannot do during this window. You can enter and work, but only for the purposes the lease permits, and only once you’ve met the prerequisites, which usually means proof of insurance and approved plans. The moment you open for business or the calendar hits the rent commencement date, the license converts into a full tenancy, and every obligation in the lease kicks in.
When the Fixturing Period Starts
The clock begins when the landlord formally delivers possession. Delivery means more than handing over keys. In most leases, the landlord must first achieve “substantial completion” of any base building work they promised: finishing the shell, installing basic mechanical systems, or completing a white box build-out. Substantial completion doesn’t mean every punch list item is done. It means the space is finished enough that you can start your work without interference from the landlord’s contractors. The specific definition is negotiated in the lease, and getting it right determines when your fixturing clock starts ticking.
Delivery is typically documented in a commencement letter signed by both parties, recording the delivery date, confirming the fixturing period duration, and establishing the rent commencement date. If your lease doesn’t require a signed letter, push for one. Verbal handoffs create ambiguity, and ambiguity about when fixturing started becomes a dispute about when rent should have begun.
If the Landlord Delivers Late
Landlords don’t always deliver on time. Construction runs behind, permits stall, or a prior tenant hasn’t vacated. A well-drafted lease addresses this with a delayed possession clause. The most common remedy is a day-for-day postponement: if the landlord delivers 15 days late, your fixturing period, rent commencement date, and sometimes even the lease expiration date all slide by 15 days.
If the delay is severe, many leases give the tenant the right to terminate entirely. A typical threshold is 60 to 120 days past the promised delivery date. The landlord returns any prepaid rent and security deposits, and both parties walk away. If your lease doesn’t include this protection, negotiate for it. Being locked into a lease for a space you can’t access is one of the worst positions a commercial tenant can occupy.
When the Fixturing Period Ends
The period terminates on whichever comes first: the date specified in the lease, or the day you open for business. Most leases set a fixed duration between 30 and 90 days, though complex build-outs for restaurants or medical offices sometimes negotiate 120 days or more. If you finish early and start serving customers, the fixturing period ends immediately and rent obligations begin, regardless of what the calendar says.
This early-opening trigger catches tenants off guard. A soft launch, a friends-and-family event, or even letting a few customers in to test things can be interpreted as opening for business. If you want to run trials without starting the rent clock, make sure the lease defines exactly what constitutes “opening” and carves out exceptions for testing and training activities.
Whether you can extend the fixturing period depends entirely on what the lease says. Some leases allow extensions with landlord consent, often at a cost. Others are rigid: the period ends on the stated date regardless of whether you’re ready. In the absence of an extension clause, the rent commencement date arrives on schedule even if your contractors are still hanging drywall. Negotiate extension rights during the drafting stage when you still have leverage, not after you’re already behind.
What You Can Do in the Space
The fixturing period is for installing trade fixtures and completing the soft build-out that turns a bare space into your business. Trade fixtures are items you attach to the property for business use but retain the right to remove when the lease ends. Commercial kitchen equipment bolted to the floor, custom shelving, point-of-sale stations, interior signage, and display cases all qualify. The defining feature is that these items serve your business specifically and aren’t permanent improvements to the building itself.
Cosmetic work also happens during this window: painting, decorative lighting, carpet or vinyl flooring, and furniture setup. So do operational tasks that don’t involve construction, like stocking inventory, training staff, testing equipment, and configuring technology. These soft tasks are easy to overlook when planning your timeline, but they eat days fast.
Structural modifications are different. Moving walls, upgrading electrical panels, modifying plumbing, or altering HVAC systems typically require building permits and may fall outside what the fixturing period covers. Many leases handle these under a separate tenant improvement provision with its own timeline, budget, and approval process. If your build-out requires both structural work and fixture installation, coordinate the sequencing carefully. Permit delays on structural work can cascade into your fixturing schedule and push back your opening.
Even non-structural work can trigger permits depending on jurisdiction. Installing a commercial kitchen hood, modifying fire alarm or sprinkler connections, and adding new electrical circuits typically require inspection. Fire safety inspections are common before any commercial space opens to the public. Build time into your schedule for the possibility that an inspector flags something requiring correction before you get the green light.
What You Still Pay During Fixturing
Base rent is almost always waived. That’s the point of the period: time to prepare without paying for space you can’t yet use to generate revenue. But “no base rent” doesn’t mean “no costs.” Most leases require you to pay additional rent during fixturing, a catch-all term for operating expenses the landlord passes through.
The common charges during fixturing:
- Utilities. You’re using electricity, water, and sometimes gas during construction and setup. These are almost always your responsibility from day one of access.
- Common area maintenance (CAM). Your proportionate share of maintaining shared spaces like lobbies, parking lots, and landscaping. Retail CAM commonly runs $3 to $10 per square foot annually; office buildings often run higher.
- Waste removal. Construction debris from your build-out is your problem. Some landlords arrange dumpster service and bill you; others require you to hire a hauler.
- Security deposits or access fees. Some properties charge for after-hours access or require a refundable deposit against damage to common areas during construction.
Negotiate these line items before signing. The total can be meaningful, especially for larger spaces, and landlords have more flexibility on these charges than they initially let on. Getting a cap on CAM during fixturing, or having the landlord cover utilities for the first 30 days, are common concessions in competitive markets.
Fixturing Period vs. Free Rent Period
These two overlap enough to cause confusion. A fixturing period grants physical access for build-out work before the lease term starts. A free rent period, sometimes called a rent abatement period, waives base rent for a set number of months after the lease term has already begun. You might have both: 60 days of fixturing to build out, followed by two months of free rent once the term starts, giving you time to ramp up revenue before the full financial weight lands on you.
The practical difference is what you owe. During fixturing, you typically pay only operating costs. During a free rent period, base rent is waived but you’re a full tenant subject to every other lease obligation. Some leases tie the free rent period directly to the fixturing period so they run concurrently; others keep them sequential. Push for clarity on which costs are waived during each phase, because landlords sometimes define “rent” narrowly enough that additional charges still apply.
Insurance You Need Before Getting the Keys
You won’t get access until you hand the landlord certificates of insurance. This is non-negotiable in virtually every commercial lease. A build-out involves contractors, heavy equipment, power tools, and exposed wiring in a space the landlord still owns.
Standard requirements include:
- Commercial general liability (CGL). Most leases require a minimum of $1 million per occurrence and $2 million aggregate. This protects against bodily injury and property damage claims arising from your work. The landlord will be named as an additional insured.
- Builder’s risk insurance. Covers the value of materials and work in progress against fire, theft, vandalism, and certain weather events. A $50,000 build-out puts $50,000 in materials and labor at risk before you open.
- Workers’ compensation. Required by law in nearly every state for businesses with employees. If you’re hiring contractors, verify they carry their own coverage. In many states, if a subcontractor’s uninsured employees are injured, liability can flow uphill to whoever hired them.
Let your insurance lapse during fixturing and the landlord can immediately suspend your access. Some leases make this an automatic default. Getting policies in place and certificates issued takes time, so start the process when you’re negotiating the lease rather than after you sign.
Penalties If You Open Late
Many retail and shopping center leases include a continuous operation clause requiring the tenant to open by a specific date, often tied to the end of the fixturing period. If you miss it, consequences range from annoying to severe. Some leases impose per-diem charges or accelerated rent. Others treat a late opening as a lease default, triggering cure periods and, if uncured, termination. Courts have upheld provisions requiring tenants to pay double rent for each day the business wasn’t operating, provided the amount was a reasonable estimate of the landlord’s actual damages rather than a pure penalty.
Build a buffer into your fixturing timeline. Contractors almost always take longer than quoted, and permit delays are common enough that planning for them isn’t pessimism.
Tenant Improvement Allowances
Many landlords offer a tenant improvement (TI) allowance to offset build-out costs. This is a dollar amount, often calculated per square foot, that the landlord contributes toward your construction and fixturing. Office and industrial leases commonly see allowances of 5% to 10% of annual rent; retail leases may offer 10% to 20%, reflecting the typically higher build-out costs for consumer-facing spaces.
The allowance is a ceiling, not a guaranteed payment. If the landlord offers $15 per square foot and your build-out costs $20, you cover the difference. How the money reaches you varies. The three common disbursement methods are reimbursement (you pay contractors, then submit invoices for repayment), direct payment (the landlord pays your approved contractors), and rent credit (unused allowance reduces future rent). Reimbursement is the most common, which means you need enough working capital to fund the build-out upfront and wait for repayment. Factor this cash flow gap into your planning.
TI allowances and fixturing periods are related but separate. The allowance covers costs; the period covers time. You can have a generous TI allowance but a short fixturing period, or vice versa. Make sure both are adequate for your scope of work, and understand that the approval process (submitting plans, getting bids, landlord sign-off) should happen well before fixturing begins so you don’t burn fixturing days waiting for financial approval.
What Happens to Your Fixtures at Lease End
Everything you install during fixturing eventually has to be dealt with. Most commercial leases require you to surrender the space in “broom clean” condition: empty, swept, and free of your property. Trade fixtures you installed are yours to remove, but you’re responsible for repairing any damage the removal causes. Pull out a bolted-down display case and leave holes in the concrete, and that’s your repair.
The landlord often has the right to require you to remove specific alterations or improvements beyond trade fixtures. Custom built-ins, specialty flooring, internal walls you added, and similar modifications may need to come out at your expense. Ask the landlord during initial lease negotiation to identify, in writing, which improvements must be removed at lease end. That commitment upfront prevents an expensive surprise when you’re already dealing with the cost of moving out.
If you leave property behind, most leases let the landlord treat it as abandoned, then remove, store, sell, or dispose of it and bill you. The obligation to restore the space and cover these costs typically survives the lease termination, meaning the landlord can pursue you for restoration expenses even after the lease is over.
