Carriage Houses NW: ADU Builders Serving the Pacific Northwest
The Pacific Northwest is facing a sustained housing crisis, and addressing it requires a variety of thoughtful housing solutions. Carriage Houses NW is a specialized ADU builder and infill housing developer focused on maximizing the potential of existing single-family residence (SFR) properties throughout the region.
Recent Washington State housing legislation has opened significant doors for increased residential density. House Bill 1110 allows for a fourplex to be constructed on a traditional single-family lot, while House Bill 1337 permits up to two accessory dwelling units on a single SFR property. Carriage Houses NW is well-positioned to help property owners and investors take full advantage of these legislative changes.
Their Core Services and Business Model
Carriage Houses NW operates across three distinct areas of focus as an accessory dwelling unit builder and infill developer:
- Property acquisition and development: Their primary business involves purchasing existing single-family residences and constructing additional ADUs, duplexes, or townhomes on those properties. Completed projects may be sold or retained as long-term rental properties.
- Homeowner partnerships: They also consider opportunities to partner directly with homeowners who want to build additional units on their own property, making them a practical choice as a detached ADU builder or granny flat builder for those looking to add value to their existing land.
- Fee-to-build construction: On a selective basis, Carriage Houses NW takes on construction projects for individual customers on a straightforward fee-to-build basis.
A Focused Approach to Infill Housing
As an experienced ADU contractor operating in a region with growing housing demand, Carriage Houses NW brings a targeted and knowledgeable approach to infill development. Their work directly supports the goals of Washington State's housing legislation by creating more homes within existing neighborhoods — without the need for large-scale land development.
Whether a property owner is looking to add a backyard cottage, explore a partnership on a multi-unit project, or simply get a fee quote for a new build, Carriage Houses NW offers a structured process to evaluate each opportunity and determine the best path forward.
