Property compliance, built for New York — and nowhere else.
Lot & Block automates HPD violations, DHCR and rent-stabilization tracking, and HPS placement for NYC landlords and property management companies — so your team stops doing manual lookups and starts managing at scale.
No portal logins. No spreadsheets. Live in under a week.
Your property software was built for fifty states. None are New York.
Manual violation lookups
Someone on your team checks the city portal for every building, every week. A missed violation means a missed deadline — and compounding fines.
Stabilization tracking in spreadsheets
Rent stabilization in Excel is a liability. One wrong number is an overcharge complaint waiting to happen.
Legal prep takes hours
Pulling ledgers, scanning notices, emailing lawyers. By the time the file is ready, you’ve lost two weeks of rent.
Everything NYC compliance demands, in one system.
Live HPD violation sync
We watch every building automatically. New violations surface instantly, grouped by class, with alerts before deadlines hit — no portal, no spreadsheet, no missed Class C.
DHCR compliance engine
Rent-stabilization tracking, preferential-rent enforcement, and DHCR registration status at the unit level — with a court-ready PDF in one click.
Append-only rent ledger
A tamper-proof rent history that satisfies DHCR audit requirements and gives your attorney everything they need in seconds.
HPS placement pipeline
Full DHS referral intake, screening coordination, and placement tracking for your set-aside units — every referral, every caseworker, every document, in one place.

Your whole portfolio, indexed.
An agent on every filing — that drafts the response and cites every line.
When a noncompliance code lands, the agent reads the case and drafts a corrective action plan grounded in regulatory canon — so your team starts from a cited first draft instead of a blank page.
Proposed corrective action plan
This is a proposed plan for review by your compliance manager — not a final legal determination. The cited noncompliance concerns Unit 4B’s annual income recertification for TY 2024. Proposed remediation: perform and fully document the recertification, submit all materials the monitoring agency requires, and assess any Available Unit Rule implications before filing.[1] [2]
Decide between (a) a current recertification using present income and limits, or (b) a retroactive recertification documenting income as of the original due date.[1] [3]
- Current or retroactive recertification for Unit 4B, given the Available Unit Rule trade-offs?
- What document deficiency triggered code 11b — missing verifications, miscalculation, or no recertification on file?
From manual chaos to managed compliance.
Connect your portfolio
Your buildings, units, and BBL numbers index automatically from NYC Open Data. No manual entry, no spreadsheet imports.
Compliance surfaces on its own

The work gets prioritized
Class C emergencies, overcharge exposure, and missing lease data rise to the top, so your team acts on signal, not noise.
Legal prep in one click
Court-ready DHCR PDFs, tamper-proof ledgers, and HPS placement records — generated in seconds, not assembled over hours.
