A commercial lease addendum is a document that adds to the terms of an existing commercial lease. It’s generally used when the landlord and tenant desire to introduce new rental conditions but don’t want to terminate the original agreement. The addendum allows the parties to clarify payment obligations, extend the lease duration, increase the rentable space, or expand upon other conditions recorded in the initial contract. It can also resolve issues not addressed in the original lease (e.g., insurance obligations, designated parking zones).

CONTENTS

Common Lease Modifications & Additions

A commercial lease addendum can be used to adjust or expand upon a variety of terms in an existing rental agreement, such as:

  1. Payment Terms – If the original lease didn’t specify when or how the tenant must pay rent, the landlord could clarify these terms using a commercial lease addendum.
  2. Subleasing – An addendum can grant subleasing rights, allowing the tenant to rent out a portion of their commercial space to another business entity.
  3. Lease Duration – The parties can use a lease addendum to extend the original lease without affecting other terms in the rental agreement.
  4. Renewal Options – Landlords can use an addendum to add a lease renewal provision to the rental agreement. Unlike a lease extension, a lease renewal generally involves an increase in the monthly rent.
  5. Expense Obligations – A commercial lease addendum can reassign maintenance costs, utility fees, and other expense obligations.

Additional Space & Property Improvements

It’s common for landlords to modify commercial property when a tenant’s business outgrows the available space. Sometimes, a commercial unit might be too large, and the tenant would like to cut costs by downsizing to a smaller area. When this happens, a commercial lease addendum can be employed to expand or reduce the square footage designated for the tenant’s use.

A lease addendum can also document the landlord’s restorations or improvements to a commercial property. Some common alterations include:

  • Lobby repairs
  • New lighting and decor
  • Painting
  • Adding cubicles and offices
  • Installing/upgrading signage
  • Building ramps and accessibility options for the disabled

Frequently Asked Questions

Does the tenant need to consent to the addendum?

Yes. The tenant must agree to the changes and sign the addendum for the lease alterations to be considered legally binding.

Does an addendum replace the original lease terms?

No. Unless explicitly stated otherwise, a lease addendum does not replace terms in the original commercial lease agreement. Instead, it simply incorporates new provisions into an existing rental contract.
