# Alteration/ Improvement Provisions in Leases to Improve Climate/ Environmental Impact of Buildings and Better Use of Shared Space

## Child’s name

Dorothy’s Clause

## Summary

This clause requires landlords to act reasonably when tenants propose alterations to their premises (and changes of use) or improvements to common areas, which have a positive climate impact.

## What this clause does

Helps tenants negotiate for the rights to carry out environmental improvements knowing that landlords must act reasonably in approving these. The clause also encourages more efficient use of land and buildings and more collaboration between landlords and tenants to achieve climate goals.

## Clause Content

*\[Drafting note: Capitalized terms relate to either a defined term in this clause or a defined term in the main agreement that this clause is designed to be inserted into.\]*

**For Tenant’s Alterations section**

Notwithstanding the provisions of Section \[●\] of the Lease relating to Alterations to the Premises, Tenant may, with Landlord’s consent, not to be unreasonably withheld, conditioned, or delayed, carry out \[structural and\] non-structural Environmental Improvements to the Premises \[or to unbuilt parts of the Real Property\]. Landlord can refuse consent to any proposed Environmental Improvements that in Landlord’s reasonable opinion would have a \[material\] detrimental impact on the investment value of Landlord’s reversionary interest in the Premises, Building or the Real Property.

**For Tenant’s End of Term section**

By the Expiration Date, Tenant shall have removed \[*INSERT DETAILS*\] and restored the Premises in accordance with Section \[●\] of the Lease, provided, however, that Tenant shall not be required to remove any Environmental Improvements \[unless Landlord has given Tenant at least \[●\] months’ notice that it requires Tenant to remove all or part of any Environmental Improvements on the basis that those works remaining after the Expiration Date would have a \[material\] detrimental impact on the investment value of Landlord’s reversionary interest in the Premises, Building or the Real Property\].
