What the statute says a deposit may be kept for

Only amounts reasonably necessary to repair or clean the premises or remedy a default; itemized statement plus receipts/invoices; bad-faith failure means the landlord cannot claim any part of the deposit.

What happens if the deadline is missed

If the deposit is not returned on time and if a court finds the landlord acted in bad faith, the statute allows statutory damages of up to 2× the amount of the deposit, in addition to actual damages.

Penalty amounts depend on facts a court or agency decides. The letter states the statutory exposure as possible, never as money already owed.

Questions about a California deposit letter

What deadline will the letter use?

The deadline is computed from the dates you enter using the rule recorded for California: 21 calendar days after the date you moved out.

Can the letter claim a penalty?

Where the statute has a verified penalty, the letter states it as possible exposure and names the condition the statute sets. If the deposit is not returned on time and if a court finds the landlord acted in bad faith, the statute allows statutory damages of up to 2× the amount of the deposit, in addition to actual damages.

What if the landlord sent an itemized statement?

Tell the builder that you received one. The letter acknowledges it and disputes the amounts you say are wrong.

Is this legal advice?

No. It is a self-help document tool, not a law firm. If your claim is large or disputed, speak to a landlord-tenant lawyer or legal aid.
