If you’re considering an ADU in Solana Beach, a garage conversion can be one of the smartest paths—if the structure and site conditions work in your favor. The goal is to confirm feasibility early so you don’t burn time and money on drawings that can’t be permitted.

Here’s a practical, builder-style checklist for Solana Beach garage conversions and ADUs—with the big decisions up front.

Quick takeaways

  • Confirm feasibility before design: ceiling height, slab condition, utilities, parking, and setbacks.
  • Coastal-zone rules and exterior changes can add complexity on some properties.
  • Design wins come from natural light, storage, and a simple, durable finish palette.
  • The best ADU projects feel like a small, high-quality home—not a “converted garage.”

Feasibility checklist: the “yes/no” items

1) Ceiling height + structure

Low ceilings and odd framing can limit layouts. We check clearances, rafters/trusses, and whether a new ceiling strategy is needed.

2) Slab condition and elevation

Garage slabs can be sloped, cracked, or low relative to grade. If plumbing needs to be added, slab work may be required.

3) Utilities: water, sewer, electrical

Where do the lines run? Are they sized for an additional unit? Sometimes the simplest design is the one that stays near existing connections.

4) Parking requirements

Parking can affect feasibility—especially when converting a garage that currently provides required spaces. We confirm early so the project stays compliant.

5) Windows, doors, and egress

ADUs need proper egress and light/ventilation. Adding windows and doors can trigger exterior approvals depending on the property and location.

Design moves that make a garage conversion feel “built,” not “converted”

  • Use a clean, consistent flooring strategy (avoid overly thick transitions).
  • Add a real kitchen zone with proper storage.
  • Layer lighting: recessed + decorative + task lighting.
  • Include sound control where neighbors are close (insulation, sealed penetrations).
  • Choose coastal-friendly finishes that clean easily.

What typically drives ADU costs?

  • Structural upgrades (if needed)
  • Slab and plumbing additions
  • New windows/doors and exterior work
  • Kitchen and bath finish level
  • Utility upgrades and service capacity

The clearest way to manage cost is a defined scope + early finish-level decisions.

A realistic planning timeline

Most projects follow a path like:

  1. Feasibility + concept
  2. Design + plans
  3. Permitting and approvals
  4. Construction
  5. Final inspections and handoff

    6. If you want to move fast, order long-lead items early and finalize selections before demo.
