What counts as an ADU (and what doesn’t)

By RemodelSD | January 09, 2026 | Encinitas

In simple terms, an ADU is a smaller, independent living space on the same property as a primary home. Encinitas homeowners typically consider:

  • Detached ADU: a separate structure (backyard cottage)
  • Attached ADU: connected to the main home (often like a suite addition)
  • Garage conversion ADU: converting an existing garage into living space
  • Junior ADU (JADU): a smaller unit created within the existing home footprint (rules differ)

Which option is “best” depends on your lot shape, privacy needs, budget priorities, and how you plan to use the unit.
