Cleaning An Apartment Before A Pet Moves In

Two separate jobs: removing what the last animal left, and making the apartment safe at the height your own will live at.

Start with the animal that was here before

Apartments turn over between pet owners constantly, and a standard turnover clean does not remove much of what an animal leaves behind. Hair works into carpet edges and along baseboards, and odor sits in the carpet pad rather than on the surface.

Two reasons to deal with it now. Your own animal will react to another animal's markings, sometimes by marking over them, which is a problem that is far easier to prevent than to fix. And anything already there becomes indistinguishable from your pet's damage at move-out unless it is on record.

What to clean before the animal arrives

  • Carpet edges and the perimeter along the baseboards, where hair collects and vacuums rarely reach.
  • Baseboards and the bottom of door frames, washed rather than wiped.
  • Closet floors and the space under built-in units.
  • Vent covers at floor level, which collect hair.
  • The balcony or patio floor and its drain, if there is one.
  • Any spot on the carpet that smells stronger when it is damp, which is the classic sign of a previous accident in the pad.

If a damp patch smells and surface cleaning does not change it, that is in the pad. Raise it with the building before your animal arrives, because once it is there, the argument about whose it was becomes unwinnable.

Then look at the apartment from their height

  • Cleaning products moved out of low cabinets, or the cabinet secured.
  • Gaps behind and under the fridge, stove, and washer closed off where you can do it reversibly.
  • Loose cables tucked or covered, particularly around a work desk.
  • Balcony railings checked for gaps, and anything climbable moved away from them.
  • Houseplants checked, since several common ones are toxic to cats and dogs.
  • Bin with a lid rather than an open one, which prevents a category of problem entirely.

Set up the areas before the animal, not after

Decide now where the litter tray, the food bowls, and the bed go, and clean those spots properly first. A litter area on a hard floor with a mat under it is far easier to keep than one that migrates to carpet after two weeks.

Food and water bowls belong somewhere with a wipeable surface underneath. The floor around bowls is one of the places that gets sticky invisibly and then smells, and choosing the spot deliberately avoids months of that.

Photograph everything first

Before the animal is in the apartment, take photographs of the carpet in every room, the baseboards, the bottom of the doors, the door frames, and any existing stain or mark. Date them and keep them with your move-in set.

Pet clauses and pet deposits make move-out inspections more detailed, and scratches on a door frame or a stain in a corner are exactly what gets attributed to the most recent animal. A dated photo set taken before your pet arrived is the only thing that separates what was already there from what was not.

Worth checking in the lease first

Confirm what the pet clause actually requires: a deposit, monthly pet rent, professional carpet cleaning at move-out, weight or breed limits, and whether the building needs to be notified before the animal arrives.

The carpet requirement is the one that catches people. If the lease requires professional carpet cleaning with a receipt because there is a pet, that is a fixed cost at the end, and knowing it now is better than discovering it during your final week.

The empty-apartment version of all this, including carpet edges, baseboards, and vent covers, is what move-in apartment cleaning covers, and if a previous animal left real buildup, deep apartment cleaning is the version that reaches it.

Before you book

Good answers before a cleaner shows up.

Should I clean an apartment before getting a pet?+

Yes, and specifically to remove a previous animal's hair and markings. Your pet may mark over them, and anything already there becomes hard to separate from your pet's damage at move-out.

How do I know if a previous tenant's pet had accidents?+

The classic sign is a carpet spot that smells stronger when damp. If surface cleaning does not change it, the odor is in the pad, and that is worth raising before your animal arrives.

What should I photograph before a pet moves into a rental?+

Carpet in every room, baseboards, the bottom of doors, door frames, and any existing stain. Date them, because pet clauses make move-out inspections more detailed.

Does having a pet mean professional carpet cleaning at move-out?+

Many leases require it with a receipt when there is a pet. Check the pet clause when you move in rather than during your final week, since it is a fixed cost at the end.
