How to read a lease contract before signing

Most residential leases are 20 to 50 pages, and the clauses that hurt you later are almost never on the first page. Here's the short list of what to actually read before you sign — organized by how much money each clause typically costs when it goes wrong.

1. The renewal clause

Search the document for the word renew. In roughly two thirds of leases you'll find something like:

"This Agreement shall renew automatically for successive terms of twelve (12) months unless written notice of non-renewal is received by Landlord no later than sixty (60) days prior to the end of the then-current term."

Read the notice window. Sixty days is common. Ninety days is a warning sign. Anything over a hundred and twenty days is predatory — you are being set up to forget and be locked in for another year.

2. Security deposit conditions

The clause you want to find is "conditions for return of the security deposit." Look for terms like ordinary wear and tear (good), professional cleaning (acceptable), and deep clean at Tenant's expense (bad — this is often stacked as a non-refundable fee).

3. Rent escalation

Known as a CPI clause or annual escalator. Fine when capped at 3–4%. Dangerous when uncapped, or when indexed to an inflation measure the landlord chooses unilaterally.

4. Subletting and guests

Most leases prohibit subletting without written consent. Some go further and prohibit overnight guests for more than seven consecutive nights. If you travel for work and leave a partner behind, you want to read this carefully.

5. Early termination

What happens if you need to break the lease in month six? Typical clauses want two months' rent + the security deposit. Predatory clauses want the remainder of the lease term. Read this before you sign and negotiate it down — landlords will usually accept a one-month penalty if asked.

6. Dispute resolution

The last page of most leases contains an arbitration clause. You're signing away your right to sue, to join a class action, or to have a jury hear a case against the landlord. There is almost never a good reason for this clause to be in a residential lease. Ask for it to be struck out; half the time, the landlord will agree just to close the deal.
