How long does it take to get an ADU permit in Edmonds, WA?

Permit review times can vary, but it's wise to budget 3-5 months for the city's review and approval process after submitting the final architectural plans. We manage this entire submission and follow-up process for you.

What's the difference between an ADU and a DADU?

An ADU (Accessory Dwelling Unit) is a secondary living space on the same property as a primary home. It can be attached (like a basement or garage conversion) or detached. A DADU (Detached Accessory Dwelling Unit) is specifically a standalone structure, often called a backyard cottage or carriage house.

Can I connect an ADU to my existing septic system?

This depends entirely on the age, size, and current capacity of your septic system. It requires an assessment by a licensed septic designer. If the system can't handle the additional load, a new system or connection to the city sewer may be required. We can help coordinate that evaluation.

How much value does an ADU add to a home in Snohomish County?

While it varies, studies and market data suggest an ADU can increase a home's resale value by 25-35%. More importantly, it provides an immediate income stream or solves a multi-generational housing need, which has its own invaluable return.

Can Advanced Remodeling WA handle the entire ADU project from design to finish?

Yes. We offer turnkey general contractor services. This includes initial design and feasibility, architectural plans, permit management, construction, and coordinating all licensed trades through final finishes.
