California landlords who want to deduct for damage need a paper trail. A signed move-in checklist (photos help) is how you separate ordinary wear and tear from actual damage when the 21-day deposit accounting is due.
Return remaining deposit within 21 days after the tenant vacates (Civ. Code § 1950.5).
Ordinary wear and tear is not deductible.
This checklist is not a lease and does not change the rental terms.
