Normal wear and tear vs. damage: a landlord's guide

Every state prohibits landlords from deducting normal wear and tear from a security deposit. No state defines the line precisely. The result is the most-disputed area of landlord-tenant law — and the area where landlords most often overreach.

The legal definition

The standard definition: normal wear and tear is the gradual physical deterioration that occurs in any unit through ordinary, careful use. Damage is anything caused by negligence, abuse, accident, or unauthorized alteration. The test most courts apply: would this happen if a reasonable tenant lived in the unit normally?

By category

Walls and paint

• Wear: small nail holes from picture hangers, fading paint, light scuffs along walking paths, light scratches behind furniture.
• Damage: fist-sized holes, crayon or marker, cigarette burn marks, tenant-applied paint in a non-approved color, large mounting brackets removed without patching.

Carpet and flooring

• Wear: traffic patterns in walking paths, light fading from sunlight, small stains from foot traffic, slight crushing under furniture legs.
• Damage: pet urine stains, burns, tears, large food/beverage stains, gouges from furniture without pads, deep scratches on hardwood from unauthorized alterations.

Kitchen and bath

• Wear: light grease film on backsplash with normal cleaning, calcium buildup on faucets, mineral staining in toilet bowl.
• Damage: baked-on grease that requires degreaser + scrape, mold growth from chronic neglect, cracked tile from impact, broken fixtures from misuse.

Appliances and fixtures

• Wear: dimming oven bulbs, scuffed appliance fronts, worn refrigerator gaskets at end of useful life.
• Damage: cracked oven glass, missing knobs, refrigerator interior staining requiring replacement, dishwasher damage from running with food debris.

The depreciation rule

Even when something is clearly damaged, you usually can't deduct full replacement cost if the item was old. Most jurisdictions and judges expect deductions to be depreciated by useful life:

• Carpet: 5–10 years depending on grade.
• Interior paint: 2–4 years.
• Appliances: 8–12 years.
• Hardwood floors: 25+ years (rarely depreciated to zero).

If you replace a 7-year-old carpet (10-year useful life) damaged beyond repair, the deductible amount is roughly 30% of replacement cost — the remaining useful life. Charging full replacement is the fastest way to lose a small-claims case.

The length-of-tenancy effect

The longer the tenancy, the more deterioration is presumed normal. A unit shows almost no wear after 6 months and substantial wear after 4 years; the deduction window narrows accordingly. This is why long-tenured tenants often get deposits returned in full even when the unit visibly needs work — the work is the landlord's normal turnover cost.

When the call is genuinely ambiguous

Some findings sit on the line — a 2-inch scratch in hardwood, a stained-but-cleanable carpet, mineral buildup in a fixture. Two practical principles:

1. When in doubt, classify as wear. The penalty for over-deducting (often 2× or 3× the disputed amount plus fees) is far worse than the cost of the disputed deduction itself.
2. Document anyway. Even if you don't deduct, photograph and itemize with a 'normal wear, no deduction' note. If the next tenant's case touches the same area, you have a paper trail.
