ADU Services – Puget Sound

ADU Planning, Permitting & Layout Services – Puget Sound, WA

🏠 Build Smart. Build Legal. Build Local.

Whether it’s a backyard cottage, a rental unit above the garage, or a home for extended family—ADUs (Accessory Dwelling Units) are one of the smartest ways to increase property value and housing flexibility.

But every city has different rules, and every permit reviewer wants something slightly different.

At JWS Consulting, we guide homeowners, designers, and builders across the Puget Sound through the full ADU journey—from concept to final inspection.

🛠️ What We Help With

We simplify a complex process. We know what your city is going to ask, and we prepare your ADU submittal for fast, clean approval.

✅ ADU services include:

• Jurisdiction-specific code research

• Setback, size, and zoning analysis

• Site plan and layout preparation

• Permit-ready plan creation (or coordination with your designer)

• Structural plan review and corrections

• Submittal support and tracking

• Inspection prep (energy, fire separation, access)

🧠 We know what triggers extra reviews—and how to avoid unnecessary delays.
