Sublease Agreement: What to Include (Owner Approval and Guest Agreements)

Every sublease rests on two documents. The first is the owner's written approval, which gives the tenant permission to sublease. The second is the agreement with the subtenant or guest, which sets the terms of each stay. Most problems in rental arbitrage trace back to one of these being vague, missing, or signed by the wrong person.

This guide is a checklist for both. It is general information, not legal advice; sublease law varies by state, and a licensed attorney should review any document you plan to rely on.

Part 1: The owner's written approval

This is the document that turns a regular lease into one you can operate on. It is often a lease addendum signed with the lease, or a signed consent letter. Whatever the form, it should cover the following.

The property

• Full street address, unit number, and any parking or storage included.
• A reference to the lease it modifies, by date and parties.

Who may sublease

• The tenant's name, and if you operate through a business entity, the entity's legal name.
• Whether the tenant may use a co-host or property manager to run day-to-day operations.

The permitted use

This is the most important section, and the one most often left vague.

• Name the use specifically: short-term rental (nightly or weekly stays), mid-term rental (often stays of 30 days or more), co-hosting, or a combination.
• If you plan to list on booking platforms, say so.
• "Subletting permitted" or "tenant may sublet" by itself may not be read to cover a stream of short-term guests. Use plain words that match what you will actually do.

The term

• Start and end dates matching the lease.
• What happens on renewal or extension. Without this, it may be unclear whether the approval continues.
• Whether the approval survives a sale of the property, if the parties have agreed to that.

Conditions

Owners often agree with conditions. Write them down so both sides know the rules:

• maximum occupancy,
• minimum stay length,
• insurance the tenant will carry,
• cleaning and inspection standards,
• quiet hours, parking and pet rules,
• compliance with HOA rules, local permits, registration and taxes,
• how and how fast complaints will be handled,
• access for the owner with reasonable notice.

Responsibility

• That the tenant remains responsible for rent and for the condition of the property, as in the lease.
• How damage caused by guests is handled.

Signatures and authority

• Signed and dated by the owner, or by someone with documented authority to act for the owner.
• If a property manager signs, confirm in writing that they are authorized to approve subleasing.
• If the property is owned by more than one person or an entity, confirm who must sign.

When it was given

Get the approval before or at the same time as you sign the lease. An approval documented in advance is far stronger than one requested afterwards.

Part 2: The agreement with the subtenant or guest

For nightly stays booked through a platform, much of this is covered by the platform's terms and your house rules. For mid-term stays and direct bookings, you will usually want your own written agreement. It should cover:

• Parties and property: who is staying, the address, and that you are subleasing under your lease.
• Dates: check-in, check-out, and what happens with early departure or extension.
• Rent and fees: amount, due dates, payment method, cleaning fees, and any taxes.
• Deposit: amount, what it covers, and when and how it is returned. Deposit rules vary by state.
• Occupancy: who may stay, guest limits, and pets.
• House rules: noise, smoking, parking, trash, and any HOA rules guests must follow.
• Condition and damage: inspection at move-in and move-out, and responsibility for damage.
• Maintenance and access: how to request repairs and when you may enter.
• Termination: what ends the agreement early and what notice applies.
• Upstream lease: that the stay is subject to your lease and the owner's rules.

Mid-term stays can trigger ordinary landlord-tenant rules in some places, including notice and eviction procedures. Ask a licensed attorney how your state treats stays of the length you offer.

A quick test for any approval

Before you rely on an approval, ask:

1. Could a stranger read this and know which unit it covers?
2. Could they tell what use is allowed, in plain words?
3. Could they tell for how long, including renewal?
4. Is it signed by someone with authority?
5. Was it given before you committed?

If any answer is no, fix it before you sign.

Example structure for an approval addendum

Without drafting legal language, a clear approval addendum often follows a structure like this:

1. Parties and lease: the owner, the tenant or entity, and the lease being amended.
2. Property: the full address and unit.
3. Permitted use: the specific use or uses, in plain words.
4. Term: matching the lease, plus renewal and extension language.
5. Conditions: occupancy, minimum stay, insurance, standards, compliance.
6. Responsibility: rent, condition, damage and complaints.
7. Access and communication: inspection notice and a contact for issues.
8. Signatures and dates.

Use this to organize a conversation with your attorney rather than as a substitute for one.

Common mistakes

• Relying on a verbal yes or a text. Better than nothing, much weaker than a signed document.
• Generic wording. The use is the point. Name it.
• No renewal language. Approvals that silently expire with the first lease term are a common surprise.
• Wrong signer. A leasing agent without authority cannot bind the owner.
• Treating the owner's approval as the only permission. HOA and city rules still apply. See is rental arbitrage legal and researching city STR rules.
• No guest agreement for mid-term stays. A booking confirmation is not a lease.

Where Zi-Find fits

On Zi-Find, a sublease-approved property is one where the owner has agreed in writing that the tenant may sublease for a named use. Property finders and realtors who list on Zi-Find are expected to have that written approval, and the help article what counts as written sublease approval explains the standard listings are held to. Owners can list their own properties for free on for owners.

Zi-Find is a marketplace, not a brokerage and not a law firm. It does not draft your lease or approval, takes no cut of any deal or rent, and the lease is always between the operator and the owner.
