Landlord compliance,
without the guesswork.
LandlordOS turns local housing ordinances into property-specific compliance actions, required notices, and defensible proof records.
01 — The Problem
Housing law is no longer simple,
stable, or forgiving.
In regulated cities like Los Angeles, compliance obligations are scattered across ordinances, agency updates, required postings, notice rules, and effective dates. Missing one requirement can create fines, delays, disputes, or invalid procedures.
Ordinances change
Local rules can take effect before owners realize they apply — sometimes within weeks of a council vote.
Requirements are procedural
Posting, serving, including, registering, and documenting are not the same thing — and the wrong one is no compliance at all.
Proof matters
Compliance only matters if you can show when, where, and how it was completed — preserved across years and tenancies.
02 — How it works
From ordinance to action.
LandlordOS translates complex housing rules into clear, property-specific workflows — with a defensible trail attached to every step.
Add your property
Enter the address, unit count, property type, and tenancy context. We resolve the jurisdiction stack automatically.
See what applies
LandlordOS identifies applicable ordinances, effective dates, and required actions — with the citation that triggered each one.
Complete and prove
Generate required documents, upload evidence, and maintain an exportable audit log per property and per tenancy.
03 — Capabilities
Built for defensible compliance.
Six tightly scoped surfaces — each one designed to make a specific obligation easier to meet, prove, and revisit.
Property-specific applicability
Know which rules apply to each property based on jurisdiction, unit count, year built, and rent-control status.
Required action workflows
Convert legal obligations into plain-English tasks like “post this notice” or “include this disclosure.”
Posting & notice generation
Create required PDFs with correct ordinance language, property details, and generated dates.
Proof-of-compliance logs
Upload photos, files, and completion records with timestamps — preserved per property.
Ordinance change alerts
Get notified when applicable rules change or new deadlines approach — only what affects your portfolio.
Contextual education
Understand why something applies, what mistakes to avoid, and what happens if ignored — written for owners, not lawyers.
Exportable audit trail
Every action — generated notice, uploaded photo, dismissed alert — is timestamped and exportable as a single signed record.
04 — Positioning
Not property management.
Not legal advice.
A compliance system of record.
LandlordOS is designed to help owners organize, execute, and document compliance obligations. It does not replace an attorney. It gives landlords a structured system for staying current and maintaining records.
05 — Launch market
Launching first for
Los Angeles landlords.
Los Angeles is one of the most complex housing compliance environments in the country. LandlordOS is starting with LA-specific workflows for small landlords and multifamily owners.
Example covered areas
- Rent Stabilization Ordinance workflows
- Required common-area postings
- Tenants' Right to Counsel notices
- Just Cause-related requirements
- Annual registration reminders
- Relocation assistance notices
- Language access requirements
- Habitability disclosures
Coverage will expand over time. Requirements are reviewed and structured before release. LandlordOS is not a law firm and does not provide legal advice.
06 — In practice
A requirement
becomes a record.
A new LA ordinance requires a notice to be posted. LandlordOS identifies that it applies to your property, generates the posting, prompts you to upload photo proof, and records the date, time, and action taken.
