Repairs, Damage and Ordinary Wear in San Francisco

This is worth stating explicitly because it's a common point of confusion: a tenant's habitability remedies under Civil Code § 1942 have nothing to do with the security deposit. Repair-and-deduct lets a tenant hire the repair themselves and deduct the cost from rent, but with real limits, the deduction can't exceed one month's rent per repair, and it's limited to twice in any 12-month period. Tenants using this remedy are generally expected to get estimates beforehand and keep receipts, and it's meant for genuine habitability defects, not general maintenance preferences.

Rent withholding is a related but separate remedy, flowing from the same implied warranty of habitability, where a tenant reduces payment proportionally to the severity of an unresolved defect. This carries real risk if done improperly, tenants are generally advised to document the issue thoroughly and set the withheld amount aside rather than simply spending it, since improper withholding can expose a tenant to eviction proceedings if a landlord disputes whether the underlying defect actually justified it.

4. Where wear and tear ends and damage begins

Separate from the habitability standard, which governs what the landlord has to maintain, is the question of what a tenant is responsible for when the unit's condition changes over the course of a tenancy. California law draws a real line here too: ordinary wear and tear, deterioration from normal use over time, is explicitly protected from being charged to the tenant. Damage beyond that, caused by the tenant, a guest, or another occupant, is a different category entirely.

This distinction operates independently of the Civil Code habitability list above. A worn stovetop finish after years of ordinary cooking is wear and tear; a stove that's been damaged through misuse or neglect is a different matter, and separately, if the stove simply stops working through no tenant fault, that's now squarely a habitability issue the landlord has to address regardless of who's "at fault" for the wear.

5. Security deposit deductions: what's actually allowed

When it comes to the deposit specifically, California law permits deductions only for unpaid rent, damage beyond normal wear and tear, necessary cleaning to restore the unit to its initial level of cleanliness, and remedying a tenant's default on an obligation to restore or return property. Normal wear and tear itself is explicitly and separately called out as non-deductible.

The process has real procedural requirements attached. A landlord has to provide an itemized statement and return whatever remains of the deposit within 21 calendar days of the tenant vacating. Tenants also have the right to request a pre-move-out inspection at least two weeks before the lease ends, giving them a documented opportunity to address flagged issues before the final walkthrough and the associated deduction decisions.

6. San Francisco's DBI layer: a real, verified response figure

Where a repair or condition issue also constitutes a building or housing code violation, San Francisco's Department of Building Inspection is the enforcement agency, separate from the state Civil Code process. When a violation is reported, DBI states it will send an inspector to investigate within 72 hours. If the inspector confirms a violation, they issue a Notice of Violation describing the required corrections, and the property owner then has to determine whether permits are needed, file for them within 30 days if so, complete the work, and schedule a final inspection to close the case.

An unresolved case can escalate to a Director's Hearing, and abatement fees accrue while a case stays open, with unpaid fees becoming liens on the property. Multiple liens, three or more, can result in a referral to the City Attorney's office. This is a real, sourced timeline, not an assumption, and it runs on a separate track from any Civil Code remedy a tenant might also be pursuing directly.
