City
Irvine
Irvine is a city record. City or town offices may handle local rules inside their limits, while county offices still handle records, taxes, courts, and many services.
Starting point
Confirm the address is inside local limits first.
If the address is inside Irvine, city or town offices may handle local permits, code, and services. If it is outside limits, county routing may be the better first stop.
A mailing city is not always the same as city government jurisdiction.

Directory notes
Local layers to keep on the same page.
Confirm city or town limits.
A mailing address can use a nearby place name. If the address is outside limits, county offices may handle permits, code, and land-use routes.
County still matters.
Orange County can still matter for assessor, tax collector, recorder, court, public health, social service, and election records.
Some layers are separate.
Water, sewer, fire, school, utilities, coast, earthquake maps, wildfire zones, parks, and trails may point outside city hall.
