Is Subletting Legal in Colorado? Rules and Permissions

Thinking about subletting your rental in Colorado? It’s important to know the rules before bringing in a subtenant. Colorado law doesn’t automatically allow tenants to sublet; instead, subletting depends on your lease agreement and landlord’s written consent. This article breaks down what Colorado renters need to know about subletting, permissions, official forms, and helpful resources so you can make informed decisions and avoid costly mistakes.

What Is Subletting in Colorado?

Subletting is when a tenant rents out their rental unit—or part of it—to another person (the "subtenant") for a period of time, making the original tenant responsible for the lease. In Colorado, this can offer flexibility if you need to travel, relocate temporarily, or share costs. But there are legal details you must follow to stay protected.

Is Subletting Allowed in Colorado?

There is no automatic legal right to sublet in Colorado. Whether or not you can sublet your rental depends on your lease agreement and your landlord’s approval.

• Check your lease: Most leases include a "no subletting" clause or require landlord consent.
• Get written permission: If allowed, you must obtain your landlord’s written permission before subletting.
• No lease clause? If your lease does not mention subletting, you should still ask your landlord for written approval before proceeding.

Failing to follow these requirements can lead to eviction or lease termination, so it’s essential to consult your lease and communicate clearly with your landlord.

What Does Colorado Law Say?

Colorado’s main rental housing law, the Colorado Revised Statutes Title 38 – Property – Real and Personal, does not create a right to sublet. The law defers to the terms of your lease agreement about roommates and subtenants.¹

How to Sublet Legally: Required Forms and Steps

To sublet legally in Colorado, you’ll need to complete a few key steps:

• Review your lease: Look for any "no subletting" or "written permission" requirements.
• Request permission: Use a formal request to ask your landlord. While there is no state-issued sublet permission form, you may write a signed letter or use a lease amendment.
  • Example: "I am requesting permission to sublet my apartment at [address] to [subtenant’s name] from [start date] to [end date]."
• Landlord Response: Wait for your landlord’s written approval before moving forward. Always keep copies for your records.
• Sublease Agreement: Draft a separate agreement outlining the responsibilities of you and the subtenant. Ensure it aligns with the original lease terms.
  • There’s no official state sublease form, but you can use a plain-language sublease agreement. If needed, check with the Colorado Department of Local Affairs for any updates.
• Meet Local Requirements: Some cities (like Denver or Boulder) may require subtenants to register or comply with local rules. Always check with your local housing office.

Who Handles Rental Disputes in Colorado?

Colorado does not have a dedicated residential tenancies tribunal. Disputes about subletting or rental rights are usually handled in Colorado County Courts or small claims courts. For more information, visit the Colorado Department of Local Affairs Landlord-Tenant page.

Action Steps: How to Request Subletting Permission

• Review your current lease agreement for rules about subletting.
• Write a letter or email to your landlord requesting written permission to sublet. Include your address, proposed subtenant’s name, and the dates of the sublease.
• Wait for your landlord’s written reply and keep a copy for your records.
• If given permission, sign a sublease agreement with your subtenant.
• Follow any local city requirements for subtenants or roommate registration.

This process ensures you stay in compliance and avoid disputes or fees.
