A holdover clause defines the legal consequences for a tenant who remains in possession of the leased premises after the lease expiration date without executing a new lease or renewal. Most commercial leases convert holdover tenancy to a month-to-month tenancy at a significantly increased rent — typically 125%–200% of the last month's base rent — to incentivize timely vacation and compensate the landlord for the uncertainty and potential loss of a new tenant commitment.

Holdover penalties are one of the most commonly overlooked financial risks in commercial lease portfolios. A tenant who holds over for even 60 days while finalizing a new lease can incur penalty rent of 150%–200% of normal monthly rent — a material unbudgeted expense. For a tenant paying $20,000 per month in base rent, a two-month holdover at 200% costs $40,000 in premium rent versus the normal $40,000 — an excess cost of $40,000. Portfolio managers and lease administrators must track expiration dates and initiate renewal or relocation planning at least 12 months in advance specifically to avoid holdover risk.
Negotiate to cap holdover rent at 125% rather than the 150%–200% often sought by landlords. Include a notice mechanism — requiring the landlord to notify the tenant of the holdover premium in writing before it begins accruing — to prevent the tenant from inadvertently triggering the premium. Negotiate a grace period of 15–30 days of holdover at the standard lease rate before the premium rate activates, allowing time for minor administrative delays in lease renewal execution. Ensure holdover converts to month-to-month rather than a full new annual term to preserve the tenant's exit flexibility.
Month-to-month holdover at elevated rent (most common), holdover as a renewal of the lease for a full additional term (most tenant-unfavorable), holdover subject to landlord's right to recover consequential damages from lost new tenant, and fixed penalty holdover provisions with specific dollar amounts.
Lextract extracts these fields directly from your lease PDF when this clause is present:
Commencement Date Clause
A commencement date clause defines when the lease term officially begins and, accordingly, when the tenant's obligation to pay rent commences.
Rent Abatement Clause
A rent abatement clause provides the tenant with a defined period of free or reduced rent at the beginning of the lease term — commonly referred to as "free rent" or a "rent holiday." The abatement period allows the tenant to generate revenue from the space before full rent obligations begin, partially compensating for build-out costs and the time required to establish operations in the new location..
Force Majeure Clause
A force majeure clause excuses a party's performance obligations under the lease when extraordinary events beyond their control — including natural disasters, pandemics, wars, government orders, and utility failures — make performance impossible or commercially impracticable.
