What to Know About Building or Owning an ADU in Carlsbad

Carlsbad has adopted California’s ADU-friendly laws — including SB9 and AB68 — making it easier for homeowners to convert existing structures or build new ADUs. Detached casitas, garage conversions, and interior granny flats are all legal with proper permitting.

Common types of ADUs in Carlsbad:

  • Backyard casitas with private entrances

  • Finished granny flats over garages

  • Detached guest houses permitted as ADUs

  • Junior ADUs (JADUs) integrated into the main home

Some areas may fall within coastal overlays or HOA zones, which can affect design approval. Always check with the planning department before building.
