ADUs & DADUs in Lynnwood
The Svensen Timber Collection — productized, priced, ready.
With the Lynnwood City Center and Link light rail, Lynnwood is densifying fast — prime territory for ADUs, infill, and multifamily. We build the backyard units and townhomes that turn a Lynnwood lot into real value.
Washington's ADU law changes turned the backyard into the most valuable square footage on many lots. Svensen builds detached (DADU) and attached (ADU) dwellings that add real, rentable, livable space — with the same timber craft as our custom homes.
To make the decision simple, we productized it. The Svensen Timber Collection is a set of fixed models with tiered pricing, so you know what you are getting and what it costs before the first drawing.
The Svensen Timber Collection
- Timber 800 — efficient one-bed / studio footprint
- Timber 1000 — one to two bedrooms, full kitchen
- Timber 1200 — two-plus bedrooms, premium finish
- Detached (DADU) and attached (ADU) configurations
- Permit and code navigation under current WA ADU law
- Site work, utility connections, and finish
Lynnwood is one of the better places in the county to add a unit
Lynnwood updated its development code to open up what a residential lot can carry. A lot can hold up to three units where those are single-family homes, accessory dwelling units or middle housing, and up to four where one of them is affordable.
The provision that makes Lynnwood distinctive is transit. A lot within a quarter mile of a major transit stop, meaning light rail or bus rapid transit, is allowed four units. With the City Center and the Link station, a meaningful share of the city falls inside that radius, and it is the first thing worth checking against your address.
Requirements shift as the code is refined, so we confirm the current standards with the city for your parcel before design. That way the drawings reflect what is permitted now.
- Units per lot
- Up to three where the units are single-family homes, accessory units or middle housing.
- Affordable bonus
- Up to four units where one unit is affordable.
- Transit proximity
- Up to four units within a quarter mile of a major transit stop such as light rail or bus rapid transit.
- Size
- An accessory dwelling unit is defined as 1,000 sq ft or less on the same lot as a principal unit.
- Parking
- Requirements removed for affordable and senior housing, and reduced elsewhere.
- Your address
- We confirm the current standards with the city before design.

Because we mill and engineer in-house, a productized ADU does not mean a cheap one. The Timber Collection ships with real exposed timber that a typical modular or panelized ADU cannot offer at the price.

ADUs & DADUs in Lynnwood: FAQ
Can I build an ADU or DADU in Lynnwood?
In most cases, yes. Washington’s 2024–2025 ADU law changes (HB 1337) and Snohomish County’s Ordinance 25-014 expanded ADU rights, allowing up to two units on many lots. We confirm what your specific Lynnwood lot allows during feasibility.
How much does an ADU cost in Lynnwood?
Detached ADUs in the Puget Sound typically run roughly $250K–$450K all-in as of 2025. Our Svensen Timber Collection (Timber 800, 1000, 1200) is offered as fixed tiers so you get a clear Lynnwood number up front instead of an open-ended bid.
How big can my ADU be in Lynnwood?
Most Washington jurisdictions allow ADUs in the 800–1,200 sq ft range, which is exactly why our Timber Collection comes in 800, 1000, and 1200 — sized to the rules and ready for your Lynnwood backyard.
How close to the light rail station do I need to be?
A quarter mile. A lot within a quarter mile of a major transit stop, meaning light rail or bus rapid transit, is allowed four units rather than three. With the Link station and the City Center, a good number of Lynnwood properties fall inside that radius. It is one of the first things worth checking, because it changes what is worth designing.
I read that I can only build one unit and have to live on site. Is that still the case?
Requirements have moved on a good deal in the last couple of years, and a lot of what is still findable online reflects the older picture. The practical answer is that more is possible now than most people expect. We confirm the current standards with the city for your address before design, so you get a straight answer rather than a guess.
Can I get four units on a Lynnwood lot?
Potentially, in two situations: where one of the units is affordable, or where the lot sits within a quarter mile of a major transit stop. Otherwise the limit is three units where they are single-family homes, accessory dwelling units or middle housing. Which of those applies to your address is worth establishing before design.
