What the Lease Contract Says (Legal Jargon)
“Lessee covenants and agrees to remit monthly, as Additional Rent subject to late remedies under Paragraph 6, a non-optional Doorstep Waste Assessment of $38.00 and a Resident Benefit Package of $42.00 regardless of utilization.”
What It Means in Plain English

You are forced to pay an extra $80 every single month ($960/year) for trash pickup and a “resident package” you cannot cancel—even if you carry your own trash to the dumpster.

What to ask before signing: Ask the leasing agent to waive the Resident Benefit Package or confirm your true all-in monthly rent in writing before signing.

What the Lease Contract Says (Legal Jargon)
“Absent written notice of intent to vacate delivered to Lessor no fewer than sixty (60) calendar days prior to the Expiration Date, this Agreement shall automatically renew or convert to a holdover tenancy at Market Rate plus $300.00/month.”
What It Means in Plain English

If you don’t send written move-out notice a full 2 months before your lease ends, you are locked into another lease or charged an extra $300/month penalty.

What to ask before signing: Set a calendar reminder 75 days before lease end and request that the landlord send renewal rates at least 15 days before your deadline.
Repairs & Security DepositSection 9.4 · Maintenance & Surrender
Read Repair & Deposit Guide
What the Lease Contract Says (Legal Jargon)
“Lessee shall bear the initial $175.00 service dispatch cost per maintenance occurrence for appliance or plumbing repairs, and authorizes an automatic $350.00 deduction from the Security Deposit upon surrender for carpet sanitization.”
What It Means in Plain English

You must pay the first $175 out of pocket every time an old appliance or pipe breaks, and the landlord automatically takes $350 from your deposit for carpet cleaning even if you leave it spotless.

What to ask before signing: Request that the $175 deductible apply only to tenant-caused damage and that carpet deductions only apply beyond normal wear and tear.

Frequently Asked Questions

Click any question to expand

Is my first apartment lease scan really 100% free, and how does the $3.99 Lifetime Pass work?

Yes. Your 1st apartment lease PDF scan is 100% free ($0) with no account or sign-up required. If you are comparing multiple apartments, subleases, or renewal addenda, you can unlock Lifetime Unlimited Scans for a single $3.99 one-time payment—never a recurring subscription.

What is the Portable Lifetime Pass Key and how does it work without an account?

When you pay $3.99 once for Lifetime Unlimited Scans, LeaseCheck instantly generates your personal Portable Pass Key (e.g., LC-8F4A-92C1-3B10). Because we never force you to create an account or share your email, you can copy this key and enter it on any other browser, phone, or computer to unlock your unlimited scans anywhere.

What are the most common apartment lease red flags before signing?

The most common apartment lease red flags include mandatory monthly add-on fees buried in back-page addenda (valet trash, resident benefit packages, smart lock fees), 60-day notice-to-vacate clauses with automatic renewals, per-incident repair deductibles ($100–$250), automatic security deposit carpet-cleaning deductions, and landlord entry without 24 hours advance notice.

How do I spot hidden fees in an apartment lease and calculate total move-in costs?

Add your first month’s base rent, security deposit, upfront administrative or lease preparation fees, pet deposits, and the first month of any mandatory addenda (valet trash, pest control, package lockers). Uploading your PDF to LeaseCheck extracts and totals these costs automatically in under 10 seconds.

What can a landlord deduct from my security deposit, and can they charge me for repairs?

In most US states, landlords can only deduct unpaid rent and actual tenant-caused damage beyond normal wear and tear. Watch out for leases that insert automatic flat carpet-cleaning deductions or $100–$250 per-call repair deductibles when aging appliances or plumbing fail.

How do 60-day notice to vacate and landlord entry without notice clauses work?

A 60-day notice clause requires written move-out notice 60 days before your lease expires to avoid auto-renewal or holdover penalties. For privacy, landlords may enter during true emergencies, but routine inspections or showings should require at least 24 hours advance notice.
