Landlords don't keep deposits for reasons renters expect. The usual deductions aren't "broken windows" — they're a hundred-dollar oven clean, a $150 carpet cleaning because of pet stains, a $200 wall repair for nail holes never patched, a $75 hauling fee for items left behind. Most are preventable with maintenance tasks renters can do themselves. The tasks below cover what landlord move-out checklists most commonly flag. Doing them once a quarter (or once before move-out) keeps the deposit math heavily in the renter's favor.
1. Replace the HVAC filter every 1 to 3 months
A clogged filter restricts airflow, freezes the AC coil, and can be charged back as "tenant damage" if the HVAC tech finds it. Filters are $5 to $15. The fight over a $400 service call to thaw a frozen coil isn't worth losing.
Check monthly, replace every 1 to 3 months. Take a photo of the new filter with a date written on it — useful if the landlord ever questions whether you maintained it.
2. Clean the dryer lint trap and check the vent yearly
Lint trap every load is obvious. Less obvious: many leases make the tenant responsible for the dryer vent run. Restricted vent = long dry times = the next tenant's complaint and your $150 deduction. Use a vent brush or a vacuum attachment once a year, or pay a service ($75 to $150) if the vent goes through walls you can't access.
This is also the single highest-stakes maintenance task in a rental: lint fires cause house fires, and the fire department will document it as preventable.
3. Patch nail holes and minor wall scuffs before move-out
Spackle is $5. A putty knife is $3. Touch-up paint matched at any hardware store is $20. Total time: 30 minutes for a typical apartment. A landlord charging back wall repair to a deposit usually marks it at $50 to $200 per room.
Keep the leftover paint cans the landlord left under the sink. If there aren't any, take a photo of an unscuffed section of wall in good light and bring it to a paint counter for color matching.
4. Clean the oven before move-out — and once mid-lease
"Move-out oven cleaning" is a flat fee landlords charge at $75 to $200 per unit. Avoid by either: running the self-clean cycle (modern ovens, see is the self-clean cycle safe) and wiping the residue, or using a non-toxic oven cleaner spray once a year plus before move-out.
Don't forget: the oven door seal, the racks, the broiler pan, and the area under the cooktop on coil-style ranges.
5. Descale the shower head, faucet aerators, and shower glass
Hard-water deposits look like neglect even when they're chemistry. White crust on faucets and milky shower glass make a unit show poorly at walkthrough, and "deep cleaning" can be a $100 to $300 deduction.
Soak shower heads and aerators in a bag of white vinegar overnight. Scrub shower glass with a 50/50 vinegar-water spray and a microfiber cloth. Once a quarter keeps everything looking new.
6. Replace alarm batteries and confirm every alarm beeps
Many leases shift battery responsibility to the tenant. Missing or chirping alarms at move-out are a code violation in most jurisdictions and can trigger a flat-fee deduction. They're also a safety issue you'd want fixed regardless.
Test smoke and CO alarms monthly. Replace batteries yearly, or once over a typical lease. If an alarm doesn't beep when tested, tell the landlord — replacement is usually the landlord's responsibility, but only if you report it.
7. Treat carpet stains immediately, not at move-out
Old set-in stains are why landlords charge full carpet replacement ($500 to $3,000) against deposits. Fresh stains usually come out with a spray cleaner and a clean towel.
Within the first hour: blot (don't rub), apply a small amount of cleaner, blot again. For pet accidents, enzyme cleaner specifically marketed for pet stains works on the protein the standard cleaners don't reach. If a stain doesn't come out, document it with a photo so it's not blamed on you at move-out.
8. Empty the unit fully — including storage, balcony, and the parking spot
Hauling fees are a real category. Furniture left behind, items in a storage cage, a grill on the balcony, junk in the parking spot — landlords commonly charge $50 to $100 per item or a flat $200 to $500 hauling fee.
Walk through the day of move-out with the move-in inventory in hand. Check every cabinet, the storage areas, and any outdoor spaces assigned to the unit. Bring boxes for last-minute discoveries.
Bonus: the move-out photo walkthrough
The single most effective thing a renter can do for the deposit:
- Take 50 to 100 timestamped photos of every room at move-out, in good light, after cleaning.
- Photograph every surface flagged on the move-in inventory.
- Photograph the keys and the mailbox key on the counter.
- Get a signed move-out walkthrough from the landlord if at all possible.
Photos plus the original move-in inventory shift any deposit dispute heavily in the tenant's favor — most small-claims judges side with whoever has photo evidence.
The pattern
Three things connect the deductions that drain deposits:
- They're small tasks ignored over time that become big jobs at move-out.
- The landlord pays a third party flat fees that get passed to the tenant at a markup.
- None require permission, special tools, or anything outside a renter's authority to do.
A monthly 20-minute pass and a thorough move-out clean turn the typical $300 to $800 deposit deduction into $0 to $50 — usually for unavoidable wear like minor carpet flattening. The math heavily favors doing the tasks.
