Rat infestation mold rotting water damage floors and walls rotting joints and beams.
With the rats he just said to keep catching them the flooring he said to get someone to fix it and he'd take it off the rent but it's way worse than I could see yes I have emails from landlord.
Attorney Answer
Yes — under California law, a rat infestation, mold, and rotting floors, walls, and joists make a rental unit legally uninhabitable, and it is the landlord's responsibility to fix these problems, not the tenant's, regardless of what the landlord has told you to do yourself.
California Civil Code § 1941.1 defines a rental unit as untenantable when, among other things, it isn't kept free from rodents and vermin, or its floors, stairways, and railings aren't maintained in good repair — conditions that match what's been described here. A landlord's suggestion that the tenant personally catch the rats or find and pay someone to fix the flooring doesn't shift that legal responsibility.
Your options for responding are real but bounded. Civil Code § 1942 allows a tenant to repair a habitability defect and deduct the cost from rent, but this is capped at one month's rent, can only be used twice in any 12-month period, and requires giving the landlord written notice and a reasonable time to make the repair first. Withholding rent outright is a separate approach that carries real eviction risk unless it's done through a recognized legal procedure.
What you can do:
1. Continue documenting the conditions with photos and dates, and keep every email from the landlord.
2. If pursuing repair-and-deduct, send written notice of the specific defects and a reasonable deadline before doing any repairs yourself.
3. Avoid withholding rent outright without following a recognized legal procedure, given the eviction risk.
4. Consult a tenant-rights attorney given the scope of disrepair, to determine the best combination of remedies for your situation.

Frequently Asked Questions
Is a rental unit legally habitable if it has rats, mold, and rotting floors?
Generally no, most states define a habitable unit as one that's free of vermin and infestation and has floors and structural elements maintained in good repair, and these are the landlord's responsibility to fix.
Can a tenant fix habitability problems themselves and deduct the cost from rent?
In many states a "repair and deduct" remedy exists but is usually capped at a portion of monthly rent, limited in how often it can be used, and requires written notice to the landlord first.
Is withholding rent a safe way to force a landlord to make repairs?
Generally, withholding rent outright carries real eviction risk unless done through a recognized legal procedure, so tenants are usually advised to document conditions and pursue formal remedies instead.
