Yorba Linda Homes with ADU, Casita & Guest House

This page is your city-specific guide to Accessory Dwelling Units (ADUs) in Yorba Linda, CA — including how the City’s ADU ordinance, pre-approved detached ADU plan program and large-lot residential pattern shape real-world casita, guest house and multi-generational living opportunities.

Yorba Linda is known as the “Land of Gracious Living” and is best recognized as a community of single-family homes on larger lots with a high homeownership rate, equestrian trails and a strong sense of neighborhood identity. That combination makes legal ADUs and guest houses especially attractive for extended family, rental income and long-term flexibility.

Fun Fact: Yorba Linda maintains over 100 miles of equestrian trails and is widely described as a residential city of single-family homes on large lots, reinforcing its “gracious living” branding and estate-style housing stock.

Why ADUs Are a Strong Fit in Yorba Linda’s “Land of Gracious Living”

  • Large-lot single-family pattern. Yorba Linda is primarily a low-density city of single-family homes on larger lots, which often gives owners better siting options for detached ADUs, guest houses and backyard suites when they meet setback and coverage standards.
  • Local ADU ordinance with ministerial review. The City’s ADU regulations in Chapter 18.20, Article IX are implemented through a ministerial process, with applications reviewed by the Community Development Director under state timelines when complete.
  • Pre-approved detached ADU plans. Yorba Linda’s Preapproved ADU Program offers professionally designed, detached ADU plans intended to streamline permitting and support regional housing goals, which can help shorten design and review time for qualifying projects.
  • High-income, ownership-oriented market. Yorba Linda’s high homeownership rate and strong household incomes create a favorable context for ADU investments that support long-term family housing, caretakers or rental income.
  • Owner-occupancy restrictions removed under state law. California’s AB 976 makes the statewide prohibition on ADU owner-occupancy requirements permanent, giving Yorba Linda owners more flexibility in how they use permitted ADUs as long-term rentals when all other rules are met.
