You're locked in a lease but you need to exit. Or you want to move but can't afford the cost of breaking your lease outright. Subletting keeps you on the lease while someone else occupies the space and pays you — but the details of how you do it determine whether you're protected or exposed.
Subletting and Assigning Are Different — Both Matter
A sublease means you remain the primary tenant under your original lease. Your subtenant pays you, you pay the landlord, and you remain liable if the subtenant doesn't pay. An assignment means you transfer your entire lease position to a new tenant — ideally with a landlord release, so your liability ends. Subleases are simpler to structure (no landlord release needed) but riskier (you remain on the hook). Assignments are cleaner but require landlord consent and a formal release to fully extinguish your obligation. For short-term moves, a sublease is typical. For a business sale or permanent departure, assignment is preferred.
Check Your Lease Subletting Restrictions Before Starting Any Search
Before you list your space or start talking to potential subtenants, read your lease's subletting provision. Three possible outcomes: subletting is prohibited outright (rare in residential, more common in some commercial leases); subletting requires landlord approval with a specific standard (sole discretion versus not unreasonably withheld); or subletting is permitted without consent (also rare). If your lease requires landlord consent 'not unreasonably withheld,' the landlord can reject for legitimate reasons (poor credit, prohibited use, exclusivity conflicts) but not arbitrary ones. If you have 'sole discretion' language, your landlord can refuse for any reason. Know which position you're in before you start the process.
Finding a Creditworthy Subtenant Is Your Responsibility
When subletting, you're essentially taking on a landlord role while remaining a tenant. Your subtenant's failure to pay is your problem — you still owe the original landlord regardless of what the subtenant does. Screen sublease candidates as carefully as a landlord would screen tenants: run credit checks (minimum 680 score is reasonable for a residential subletter); verify employment and income (monthly income of at least 3x the sublease rent is a standard benchmark); check rental history and references; and confirm they intend to use the space for a permitted purpose. Getting a security deposit from your subtenant (typically 1–2 months rent) gives you a financial buffer if they default.
The Sublease Agreement Must Cover These Specific Issues
A sublease agreement needs to address: the sublease term (cannot exceed your original lease term); rent amount and payment timing; security deposit terms; which utilities and services are included; which original lease provisions bind the subtenant; what happens if the original lease is terminated (does the sublease terminate automatically?); and who handles maintenance requests and how. Don't use a handshake or a simple one-page agreement for anything above $1,000/month — use a proper sublease agreement reviewed by a real estate attorney. The cost of a proper sublease agreement ($300–$600 in attorney fees) is far less than the cost of a dispute with a subtenant in a poorly documented arrangement.
Profit Subletting: When Your Sublease Rent Exceeds Your Rent
If market rents have risen since you signed your lease, you might be able to sublease at above your original rent — capturing the spread as profit. This is called profit subletting, and it's perfectly legal in most states — but many commercial leases contain provisions requiring you to share profit subletting income with the landlord. A common provision: 50% of any sublease rent above your base rent is paid to the landlord. If your rent is $3,000/month and market rate is $4,200/month, the landlord claims $600/month of your $1,200/month profit. These provisions are negotiable at lease signing — push to eliminate them entirely, or limit the landlord's share to 25% of any excess.
Key Takeaways
- Subletting keeps you on the lease and liable; assignment transfers the lease with a landlord release
- Check your lease's subletting standard before starting — 'sole discretion' versus 'not unreasonably withheld' changes everything
- Screen subtenants as carefully as a landlord would — their default becomes your problem
- Use a proper sublease agreement with a real estate attorney, not a handshake or email
- Profit subletting income may be subject to sharing with your landlord per lease terms
Frequently Asked Questions
- Can my landlord refuse to let me sublet?
- In states with 'reasonable consent' statutes, the landlord cannot unreasonably withhold approval for subletting. However, landlords generally can refuse based on concerns about the proposed subtenant's financial qualifications, business type, or the subtenant's intended use conflicting with the lease.
- What happens if I sublet without permission?
- Unauthorized subletting is typically a material lease breach. The landlord can terminate your lease, evict both you and the subtenant, and potentially sue for damages. Always follow the lease's subletting procedure.
- Can I charge more than my rent to a subtenant?
- In a commercial context, you may be able to charge more (a 'profit sublet') unless your lease prohibits it. In residential leases, some states (notably New York) allow profit subletting while others prohibit it. Check your state's law and your lease terms.
- What is a sublease vs. roommate agreement?
- Adding a roommate who splits costs is different from a formal sublease. A roommate lives with you in your unit. A sublease involves you leaving the property and the subtenant taking over your space. Many leases allow roommates (up to occupancy limits) without requiring landlord approval.
- How do I screen a subtenant?
- Use the same criteria a landlord would use: credit check (minimum 680 score is common), income verification (3x monthly rent in gross income), employment verification, and landlord references. In a commercial sublet, review their business financials and intended use.
