City
Duarte
Duarte is an incorporated city in Los Angeles County with an estimated 2025 population of 22,866. It handles many rules and services inside its limits. The county still handles property records, taxes, elections, public health, and many household programs.
Starting point
Confirm the address is inside local limits first.
If the address is inside Duarte, city offices may handle local permits, code, and services. If it is outside local limits, county planning or building may handle the work instead.
What changes the answer: A mailing city is not always the same as city government jurisdiction.

The school district handles assignment and records. County offices can help with some family services, while the state licenses child-care facilities.

Los Angeles County Superior Court handles traffic court matters. A city or issuing agency handles parking. The toll operator handles toll notices.

City, county, and district responsibilities
The city line changes some rules, but not every public office.
The mailing address can say Duarte even when the property sits outside local limits. Check the city line before relying on a local rule or permit page.
City limits choose the local permit office
Inside Duarte, the city usually handles permits, zoning, parking, business licenses, and local code. Outside the city line, start with county planning or building.
The county still handles county work
Los Angeles County handles property value and tax bills. It also handles deeds, elections, health, and many aid programs. Living inside Duarte does not move those jobs to the city.
A provider can have its own boundary
Water, sewer, fire, schools, transit, trash, and power may belong to a special district or other provider. Use the address, parcel, or service bill to find the right agency.
