Lease Addendums and Side Agreements in Yukon

Leases & Agreements Yukon 3 min read · published June 24, 2026 Flag of Yukon

Lease addendums and side agreements are common additions to rental arrangements in Yukon. They can clarify permissions (pets, parking, repairs), add rules, or record agreed changes after the lease is signed. For tenants, understanding whether an addendum is legally binding, how it interacts with the original lease, and when a landlord must provide written notice is essential. This guide explains what makes a valid addendum in Yukon, what forms or records to keep, how to respond if a landlord asks you to sign one, and practical steps for disputing terms you did not agree to. Use these plain-language tips to protect your rights, keep clear documentation, and know where to file official complaints if needed.

What is a lease addendum or side agreement?

An addendum or side agreement is any written note that changes, clarifies, or adds rules to the main rental agreement after the original lease is created. Addendums can cover pet rules, parking, repairs responsibilities, temporary rent concessions, or permissions for alterations. They are separate from informal promises made in conversation: the written form matters most when there is a dispute.

A signed, written addendum is easier to enforce than a verbal promise.

When is an addendum legally binding in Yukon?

  • Signed by both parties and dated so there is a clear timeline.
  • Clearly written and documented so it can be compared to the original lease.
  • Not illegal or in violation of Yukon tenancy law or basic tenant protections.
  • Does not remove the landlords basic repair and habitability responsibilities.
Before signing any addendum, ask for time to read it and get a copy to review at home.

Common types of addendums

  • Pet agreements that set permissions, fees, or deposits.
  • Parking, storage, or exclusive use of property sections.
  • Alterations and repairs responsibilities when tenants make changes to the unit.

Practical steps for tenants when faced with an addendum

  1. Read the addendum carefully and compare it to your signed lease before you sign anything.
  2. Request a dated copy and any receipts for extra fees so you have evidence of what was agreed.
  3. Keep a dated record: save emails, photos, and messages that relate to the change.
  4. If you disagree, submit a written complaint or application to the Residential Tenancies office to start a dispute process[3].
Do not sign anything you do not understand; you can ask for a short deadline to get advice.

Official forms and when to use them

Depending on the issue, tenants may need to use official Yukon forms or follow set procedures. Common documents include:

  • Notice to End a Tenancy  use when a landlord or tenant is giving formal notice to end the rental; get a copy so dates and reasons are clear. [1]
  • Application or complaint form to the Residential Tenancies office  use when you need a formal dispute resolution about an addendum or changed term; include copies of the lease, addendum, and any supporting documents. [2]
  • Receipts and written agreements  while not always a government form, keep dated receipts for any fees or deposits tied to an addendum.
Documenting everything promptly makes remedies easier if a dispute goes to adjudication.

FAQ

Can a landlord make me sign an addendum after I move in?
No. A landlord cannot force you to sign a change. If you sign under pressure, you can later challenge the addendum through the Residential Tenancies office if it is unfair or unlawful.
What if the addendum contradicts my lease?
If the addendum conflicts with the signed lease, the later document may be enforceable only if both parties clearly intended to change the original terms; keep records and seek dispute resolution if needed.
Do verbal side agreements count?
Verbal promises are difficult to enforce. Written, signed addendums carry much more weight in a dispute, so request written confirmation of any verbal agreement.

How-To

  1. Compare the addendum side-by-side with your original lease and note any differences.
  2. Ask the landlord for a dated signed copy and keep supporting documents (emails, receipts, photos).
  3. If you cannot resolve the issue informally, file an application with the Residential Tenancies office and attach your evidence[2].
  4. Contact tenant support or legal advice if you are unsure; many jurisdictions offer guidance to renters before disputes escalate.

Key Takeaways

  • Always get addendums in writing and keep dated copies.
  • Document conversations and receipts to support your position in a dispute.
  • Use the Residential Tenancies process if you cannot agree with your landlord.
