Rent-registration ledger
DHCR · anonymizedEstimated recoverable overcharge
Illustrative, anonymized. Every figure in the product traces to a cited rule.
The product, shown
One rent history in. A complete, cited filing package out.
Drop in a DHCR rent history. The deterministic engine reads it, derives the legal rent, and returns a cited analysis — then auto-generates the entire filing package.
Defensible by design
Every number carries a citation and an audit trail.
No black box. The engine is deterministic and rule-based — each figure traces to the governing statute and the derivation that produced it. Expand any finding to see the authority behind it.
Prior lawful rent $1,798 × applicable RGB renewal (2.5%) = $1,843 max legal. Registered $2,400 ⇒ $557/mo over the lawful rent. HSTPA (eff. 6/14/2019) repealed the vacancy allowance, so no vacancy bonus was available in 2020.
Authority: HSTPA Part D · RSC §2522.8 · traced to the engine derivation ledger.
Claimed IAI raised the rent from $2,497 to $2,950. No IAI substantiation appears in the registration record; the post-HSTPA cap ($89.29/mo over 15 years on a ≤35-unit building) is exceeded. Excess over the lawful $1,955 = $995/mo.
Authority: RSC §2522.4(a) · HSTPA Part K · traced to the engine derivation ledger.
Base date is 6 years before the complaint (2020). The base-date registration ($2,400) reflects the illegal 2020 vacancy increase; the lawful base-date rent is $1,843. The difference compounds through each subsequent renewal.

FAQ
Questions attorneys ask.
No. The platform charges a flat monthly subscription. We never touch settlement money or take any share of recovery — the contingency relationship is exclusively between your firm and your client.
Every number cites the governing rule — RSC §2522.5 for renewal increases, §2522.8 for vacancy leases, §2526.1(a)(3) for the base date, the relevant RGB order for the year, HSTPA for the lookback window. The audit trail goes into your case file automatically.
No. The live lookup returns public-data likelihood and exposure signals only — never a damages figure or a guarantee of stabilization. The full cited analysis, recovery range, and document suite run inside the product on your case data.
Yes. Each subscription includes seats for attorneys and staff. Firm admins manage the roster; attorney users can intake, analyze, and update cases.
Yes. Firm cases live in a separate data model with strict per-firm scoping. No firm can see another firm’s cases, and the consumer-side flow is entirely independent. Access is protected by 2FA and a full audit log.
After the deterministic formula runs, a model pass reviews the output against the underlying registrations and flags inconsistencies or items the formula may have missed. It never replaces the formula — only adds an advisory layer.
