ADU design in Solana Beach
Solana Beach asks new ADUs to belong to their houses. That rule, plus a few on entrances and projections, shapes most designs. All from the Solana Beach ADU Submittal Process and Basic Plan Requirements (June 2025).

Matching
New-construction ADUs use the same architectural style, exterior materials and colors as the primary dwelling. Good design here is about proportion and detail within that palette.
Entrances and privacy
The ADU's primary entrance can't be visible from the street adjacent to the front yard setback. If the entrance faces the wall of another structure on the lot, keep 10 ft eave to eave.
Projections and accessory structures
- Eaves, awnings, canopies, bay windows and balconies: up to 2 ft, not into required side or rear yards
- Decks, patio covers and carports: follow zoning; not in side or rear setbacks, not on the roof
- Roof equipment shown with screening
Landscape
If aggregate landscape area exceeds 500 sq ft, a landscape package prepared by a licensed professional is required, with a planting plan, hydrozones and irrigation design under SBMC 17.56.
