Ever wish you could see exactly what your Los Angeles property is allowed to become and what work has been done on it? Whether you are buying, selling, or planning improvements, clarity saves time and money. In this guide, you’ll learn how to use the City’s own tools, ZIMAS and Atlas, to check zoning, permits, and potential risks, then set up simple monitoring so you never feel behind. Let’s dive in.
ZIMAS and Atlas explained
ZIMAS is Los Angeles City Planning’s parcel map. It shows zoning, land use, planning overlays, and case history so you can confirm what is allowed on a site and what restrictions may apply. Start with the City’s zoning search to look up any address using ZIMAS.
Atlas is the City’s map viewer used by LADBS to display building activity. You can see permit and inspection records, certificates of occupancy, and code enforcement entries, plus layers like fault zones and methane areas. Access building records via LADBS search online building records.
If a property is outside City limits, cross-check county sources. LA County’s parcel services confirm assessor data and boundaries. Use the County’s parcel layer through the LA County Assessor GIS service.
What you can see in minutes
In ZIMAS
- Zoning designation and height district, plus land use from the Community Plan.
- Overlays and restrictions like Specific Plans, HPOZ, Hillside, and RSO indicators.
- Planning case history with links to case documents where available.
- APN, parcel size, and council district.

Quick pre-offer check
- Look up the address in ZIMAS. Confirm zoning, height district, and any overlays that could affect future plans.
- Open LADBS building records. Review permits, inspection history, and any open code enforcement.
- Cross-check APN and assessor details using the LA County Assessor GIS service. If the parcel is outside the City, rely on County tools.
Deeper due diligence before you commit
Zoning and entitlements
Use ZIMAS to review planning case filings tied to the parcel. Then pull case details through City Planning’s case reports to see pending or approved discretionary actions that could impact use, massing, or setbacks.
Permits and inspections
Use the Atlas-linked systems to pull a full permit history and note status. The City’s Permit & Inspection Report helps you see whether inspections were finaled or if any permits expired.
Environmental and geohazards
Turn on hazard layers in Atlas to check for fault, flood, or methane zones. LADBS describes these layers and Building Information Online features in this overview. For complex sites, plan to consult the appropriate professionals.
Pre-list checklist for sellers
- Use LADBS building records to gather recent permits and inspection outcomes. Resolve or disclose open items before you go live.
- Confirm allowed uses, overlays, and any potential buyer constraints in ZIMAS. This helps you manage expectations around ADU potential, additions, or commercial uses.
Monitor your property over time
What the City offers
ZIMAS and Atlas are public lookup tools. They provide reports and case documents, but they do not broadly advertise per-parcel push alerts for the general public.
Simple monitoring routine
- Subscribe to City Planning email updates for your area using the email sign-up. You can also request notices for specific cases listed in case reports.
- Join your Neighborhood Council’s Early Notification System through EmpowerLA’s guidance on the Early Notification Report. This is a practical way to see nearby filings early.
- For emergency alerts unrelated to permits, register with NotifyLA.
Advanced options for power users
If you have modest technical help, you can use the City’s Open Data portal to pull planning and mapping layers on a schedule. You can also cross-check County parcel services, like the Assessor GIS service, for automated APN monitoring.
Know the limits
- Online data may lag or omit older paper records. For legal certainty, request official records from the relevant City department.
- ZIMAS covers the City of Los Angeles only. Verify jurisdiction before relying on City tools.
- Zoning interpretation can be nuanced. For firm answers on allowed uses, seek formal guidance from City Planning or LADBS.
- A finaled permit record is not a substitute for a physical inspection. Always pair records checks with qualified inspections during a transaction.
Action checklist
- Look up your address in ZIMAS and Atlas-linked LADBS records. Save date-stamped screenshots of zoning, overlays, and latest permits.
- Subscribe to Planning updates via the email sign-up and your Neighborhood Council’s Early Notification System.
- Verify APN and assessor details with the LA County Assessor GIS service.
- If you see major unpermitted work or open permits, pull a Permit & Inspection Report and plan next steps with your inspector or other specialists.
