Los Angeles County GIS Maps

Los Angeles County's geographic information system (GIS) resources help users research zoning, land use, parcels, permits, aerial imagery, and other location-based information. Choose an interactive viewer, a printable map, or a data download according to your task.

This page focuses on LA County Planning's mapping resources and links to broader County GIS data through the Enterprise GIS Hub.

Start here: The LA County Planning Maps and GIS page provides official entry points for planning maps, applications, and geographic data.

Check jurisdiction: LA County Planning's zoning and land use tools primarily serve unincorporated areas outside the county's 88 incorporated cities. Some layers cover wider areas. For a property within an incorporated city, confirm zoning and local development requirements with that city's planning department.

Independent, non-government information: This website is not affiliated with LA County Planning. We do not issue planning determinations, approve projects, or maintain the County's GIS data.

Search GIS-NET Public

GIS-NET Public combines spatial tools with planning and zoning information for unincorporated Los Angeles County. It supports property searches, map layers, subdivision research, reports, and map exports.

Information to Have Ready

Prepare the property address or Assessor's Identification Number (AIN). The official application page lists searches by AIN, address, or intersection. Use the search options and formatting instructions currently displayed in the application.

For broader research, identify the community or area involved and the subject you want to investigate. Zoning, land use, subdivision maps, permits, and aerial imagery answer different questions.

A Basic Search Sequence

Open the official GIS-NET Public page, review the terms, and select “Accept Terms and Launch Application.”
Search by AIN, address, intersection, or another option available in the application.
Confirm that the mapped location and selected parcel match the property you intended to research.
Open the Layers tab and select the information relevant to your question.
Use the available identification, query, report, or measurement tools as needed.
Print or save the map, report, or available export after checking the location, layers, and legend.

The official page links to a Quick Start Guide and an overview video. The GIS-NET Help page provides instructions for specific tools. Older tutorials may show controls that differ from the current interface.

The application supports mobile devices. A larger screen may make detailed layer review and map controls easier to use. Consult the official application page for browser guidance.

Layers, Reports, and Imagery

Map Layers and Research Tools

GIS-NET Public allows users to turn layers on and off, identify mapped features, query information, and create buffers around selected features. Layer themes group related information, while the layer filter helps locate a layer by name.

Other functions include drawing, measurement, changes to symbols and labels, adding data from other map services, and exporting available data or images. For subdivision research, the application can query and display tract and parcel maps.

Check the layer name, legend, coverage, and available descriptive information before interpreting a result. A visible parcel outline, zoning layer, and aerial photograph may come from different datasets and update cycles.

Parcel Profile Reports

The application includes parcel profile reporting. The department advises allowing browser popups for the application so reports and external links can open.

If a report does not appear, check popup permissions for the official application site. Consult the parcel profile instructions on the Help page if the problem continues.

Aerial Imagery

GIS-NET Public includes aerial imagery resources. Check the acquisition year of the imagery you select; an aerial image does not show real-time property conditions.

If an imagery layer fails to display, review current application notices and try another available imagery set. Loading time depends on the connection and amount of data requested. An incomplete display or unavailable image should not be treated as a finding about the property.

Specialized Planning Applications

The interactive GIS application directory provides focused viewers in addition to GIS-NET Public.

Z-NET and HOUSING-NET

Z-NET offers a simplified interface for land use, zoning, and related overlays. Its address or parcel search returns mapped zoning information for the selected property.

HOUSING-NET provides layers intended to assist with an SB 330 Preliminary Application. Use the corresponding planning guidance to understand application requirements; the presence of a property in a viewer does not establish project eligibility or approval.

Airport and Santa Monica Mountains Maps

A-NET, the Airport Land Use Commission viewer, includes airport locations, airport influence areas, runway protection zones, and noise contours.

The Santa Monica Mountains application provides planning information for those communities. Check the viewer's coverage and available layers for the location you are researching.

Permit Finder and Other Viewers

Permit Finder / EPIC-LA lets users review and filter available property permit information by status, type, and date. Review the individual record and contact the responsible agency when its status or meaning is unclear.

Additional thematic viewers are listed in the official application directory. Choose a tool according to its stated purpose and geographic coverage.

Printable PDF Maps

The LA County Planning Map Catalog offers prepared PDF maps free to download. Categories include supervisorial districts, countywide themes, Community Standards Districts, area and coastal plans, and community zoning.

Find the Appropriate Map

Community zoning maps are organized by Planning Area. Use the Planning Areas Lookup to search an address or select a location before browsing the catalog.

Community Standards District maps may appear individually or within an Area Plan map series organized under a Planning Area Standards District. Some series contain multiple pages for setbacks, ridgelines, or community subareas, so review the complete series relevant to your location.

Check Dates, Dimensions, and Scale

Before printing or relying on a PDF, check its preparation or revision date, legend, scale, and page dimensions. Many community maps are much larger than standard letter paper. Reducing them can make labels and parcel details difficult to read.

The catalog warns that some zoning and land use PDFs may not reflect later zone changes or plan amendments and directs users to interactive mapping applications for a more current depiction.

If a PDF differs from an interactive map, compare the dates, layers, and coverage. Ask the responsible planning agency to clarify a difference that affects your property or project.

GIS Data and Web Services

The GIS Data page provides access to planning-related geographic layers in downloadable and web-consumable formats. Public data is provided at no cost whenever possible.

Downloads and Service Connections

File Formats: Links to downloadable data formats in the Enterprise GIS Hub.
Web Service: Links to a layer's item details, where a service URL can be copied for use in a compatible map or GIS application.

The Enterprise GIS Hub includes open data from participating County departments, so its contents extend beyond Regional Planning. Availability may be limited by licensing, privacy, or third-party ownership.

Review each dataset's coverage, description, update information, and use terms. For GIS analysis, also check the coordinate system and other metadata relevant to your project.

The GIS Data page also links to the LA County Tree Hub for urban forestry and canopy datasets. Check each dataset's geographic coverage and level of detail before using it.

Interpret Map Results

LA County Planning describes its mapping information as a reference resource and does not guarantee the accuracy, timeliness, or completeness of every dataset. Interpret a result in the context of its source, date, coverage, and selected layers.

Confirm jurisdiction: County planning tools do not replace an incorporated city's planning information.
Distinguish designations: Zoning, land use policy, overlays, and permit records provide different information.
Check dates: PDF maps, imagery, and individual layers may reflect different points in time.
Verify project requirements: A mapped designation or parcel report does not itself approve a use, construction project, or subdivision.
Confirm boundaries professionally when needed: Displayed parcel lines and map measurements do not replace a boundary survey.

For a property-specific planning question, identify the address or AIN, application used, relevant layer, and issue requiring clarification. A screenshot or saved report can help explain the result, but it does not replace the responsible agency's review.
