When To Use an Addendum To Lease
You should use an addendum to rental agreement whenever you need to make changes or add something new to your current lease agreement — without creating a brand-new lease. Here are common situations:
You’re adding or removing a roommate or tenant;
The landlord now allows pets or changes the pet policy;
You want to extend the lease for a few more months;
Rent amount, payment dates, or late fees are changing;
Repairs, maintenance, or utility rules are being updated;
Any other updates that weren’t in the original lease.
