County Jurisdiction FAQ

Is my property subject to County planning and zoning requirements?

Only if it is within the County unincorporated areas. To verify, you can use the:

  • Z-NET Public is the simplest way (added January 2011). Click here to begin.
  • On-line map. If a city name appears in red, you are not located in the unincorporated area. Please contact the city. We do not regulate nor do we have zoning information about properties in the cities.
What are the County unincorporated areas?

These are communities and areas that are outside the jurisdictional boundaries of incorporated cities. As such, they are not serviced by an incorporated city. County government serves as the “city” for these areas by providing municipal services.

My property is in the County. What can I do with it?

Use the on-line map to check the zone, land use plan category, and any special district, area and plan for the property. Then check what uses are permitted in the property’s zone and land use category.

What is an Assessor’s Parcel Number (APN)?

The APN, also known as the Assessor’s Identification Number (AIN), is a 10 digit number issued by the Los Angeles County Assessor’s Office that identifies each lot or parcel in the County. The APN is usually found in this form: XXXX-XXX-XXX (e.g. 5156-006-003; map book - map book page - parcel number).

The APN for a property may be found on the grant deed or by contacting the Assessor’s office.
