Part 3: When Rent Starts And The Space Is Not Ready

Few disputes create more frustration in commercial leasing than fights over whether the premises are actually ready for occupancy and whether rent has commenced.



The landlord believes the work is substantially complete, while the tenant walks through the space and sees unfinished work, incomplete systems, missing permits, exposed wiring, nonfunctioning HVAC, blocked access areas, or contractors still moving through the premises. The landlord says the tenant can move in, and the tenant says the space is not usable. At that point, the fight is no longer theoretical because rent is about to start, contractors are still on site, opening deadlines are approaching, and both sides may already be under financial pressure. 



These disputes can become extremely expensive very quickly. A retailer may miss a holiday shopping season. A restaurant may lose momentum from a planned opening campaign. An office tenant may be forced to remain in temporary space or pay holdover rent under an expiring lease. Industrial users may have equipment arriving before utilities or electrical systems are operational.


Landlords face pressure as well. Delayed rent commencement can interfere with lender requirements, project cash flow, leasing schedules, or obligations owed to other tenants.



What “Substantial Completion” Really Means

One of the biggest problems is that many leases use vague phrases such as “substantial completion” or “ready for occupancy” without clearly defining what those terms actually mean. Everybody assumes they agree on the concept until construction falls behind schedule.



Landlords often want objective standards that trigger rent commencement as quickly as possible, such as issuance of a certificate of occupancy or sign-off by the architect. Tenants, however, frequently care less about paperwork and more about whether the space actually functions.



The tenant may insist that HVAC systems be operating properly, utilities be connected, parking areas be accessible, signage be installed, telecommunications systems be functional, and governmental approvals be in place before rent starts. Those disagreements become much more intense when the tenant’s business opening depends on the timing.



Who Caused the Delay?

Another major source of conflict is delay responsibility. Most construction delays are not caused by one event. The tenant revises the plans, the city requires additional corrections, long-lead materials are delayed, utility providers are slow to respond, contractors blame each other, permit revisions become necessary, or inspectors are unavailable. Then everybody starts arguing about who caused the delay.



Tenants often blame landlords for delayed approvals, inadequate building systems, permit problems, or delayed access to the premises, while landlords blame tenants for change orders, delayed plan approvals, redesigns, or failure to timely fund excess construction costs. Many leases contain little or no meaningful procedure for resolving these disputes.



Force Majeure Disputes

Force majeure provisions create another recurring battleground. During the last several years, supply chain disruptions, labor shortages, delayed permitting, and material availability issues triggered force majeure disputes across virtually every category of commercial construction.


Parties frequently disagreed regarding whether delays were truly unavoidable or whether they could have been anticipated and mitigated. Was the material shortage foreseeable? Should the contractor have ordered equipment earlier? Did defective plans create the permit delay? Was the labor shortage genuine?



These disputes often become highly fact-intensive and expensive. The lease should require prompt notice of force majeure claims and reasonable efforts to mitigate delays. Otherwise, force majeure provisions can easily become catch-all excuses for poor project management.



Remedies for Delayed Delivery

The remedies for delayed completion are also heavily negotiated. Landlords usually attempt to disclaim liability for delayed delivery of the premises or delayed completion of tenant improvements. Tenants, however, may face substantial business losses if the project is not completed on time.



As a result, tenants often negotiate free rent, delayed commencement dates, rent abatements, liquidated damages, termination rights, or even the right to complete the work themselves. Landlords generally resist broad termination rights because they may be left with a partially completed space, unpaid contractors, and significant unrecovered costs.



The Danger of Outside Commencement Dates

One particularly dangerous provision for tenants is the “hard” outside commencement date. Some leases provide that rent commences on a fixed outside date regardless of whether the improvements have actually been completed.



When construction delays occur, that provision can shift enormous risk to the tenant. The tenant may end up paying rent on a space that is still not fully operational.



These provisions become even more dangerous when they are not coordinated with opening covenants, lender requirements, co-tenancy obligations, or deadlines contained in other project agreements.



Rent commencement disputes are among the most operationally disruptive in commercial leasing because they arrive at the worst possible moment, when both parties are already under pressure and the business consequences of delay are immediate. Clear definitions, realistic schedules, and agreed procedures for handling delay are not just drafting preferences. They are the difference between a difficult construction project and a lawsuit.
