San Francisco · tenant tools

Moving out? Find the money in your lease and ledger.

Deposit interest nobody paid. An increase above the legal cap. A fee with no receipt. RentBack reads your San Francisco lease and rent ledger, checks them against the current rules, and cites the source behind every line — so you know what to ask about before you hand back the keys.

Counts only. No tenancy, document or name behind them is ever published. These are lifetime totals, so deleting your files and reviews never changes them. A letter is generated as a draft the tenant edits and sends themselves, asking a landlord for the money the review found; RentBack never sends it or contacts anyone. The money figures count answers to the one question after a review — how much did you get back — not people.

What this checks, your data, and the limits

Every rule the review runs

Six places money disappears — each one tied to a primary source.

Per tenancy · per document set
01

Security deposit interest

  • Whether interest applied to a held deposit
  • The published rate for each annual due date
  • Any payment or rent credit recorded as interest
  • Eligible Rent Board fee deductions
  • The government-subsidised housing exception

SF Admin Code Ch. 49 · §49.2 · SF Rent Board rate schedule

Deposit × the published rate for each due date your records cover, simple interest, never compounded.

02

Rent increases

  • The allowable annual increase for that effective date
  • Whether an increase happened inside the 12-month rule
  • Banked increases from earlier years
  • Required notice amount, form and delivery
  • Exemptions: single-family, condo, new construction
  • The statewide cap where it applies

SF Admin Code Ch. 37 · Civil Code § 827 (notice) · Civil Code § 1947.12 (statewide cap)

Overcharge is computed only for the months your ledger or payment records actually cover.

03

Fees and charges

  • Late fees and returned-payment fees
  • Cleaning, pet and administrative fees
  • Any fee clause in the signed lease
  • Charges that duplicate one already collected
  • Charges that exceed what the rules allow

Your signed lease · SF Admin Code Ch. 37 where a fee counts as rent

Counted only where the lease doesn't support the charge or the rules cap it.

04

Utility billing

  • The tenant share against the documented bill
  • Allocation methods with no stated basis
  • Charges that appear on no bill
  • Who the lease says pays which utility

The utility bill itself · Your lease's utility clause

Difference between what the bill supports and what you were charged.

05

Deposit deductions

  • Deductions with no receipt or itemization
  • Normal wear and tear versus damage
  • Charges that repeat a fee already paid
  • The itemized statement and its deadline

Civil Code § 1950.5 · SF Admin Code Ch. 49

Deductions the record doesn't substantiate, plus charges already collected elsewhere.

06

Anything else material

  • A notice that was never served properly
  • A deposit or balance the record says is still held
  • A charge that appears in no document at all

The primary source the finding relies on

Reported as a fact or an open question — never given an amount without support.

Every item above is a required check: the review returns a verdict for each one — applies, ruled out, or couldn't assess from your documents — and you can see that coverage with your findings. Every citation is pulled from the primary source at review time. If a rule can't be verified, the finding says so and stays at $0.

  • An AI model reads the two files you upload and returns fixed fields. Nothing is typed up by hand and nothing is guessed.
  • Each uploaded file is deleted the moment it has been read, even if the read fails. Only the extracted numbers stay with this browser, and one button removes them.
  • We never contact your landlord. No letter is ever sent automatically.
  • Everything here is an estimate. A finding means your records and a published rule support asking the question: not a legal conclusion, a confirmed debt, or a promise of recovery. RentBack is not a law firm and this is not legal advice. Open the source and read it yourself.
  • After a review we ask, once, whether anything came back. Only two aggregates are published: how many people reported a recovery and the summed amount. No names, addresses or per-person amounts.
