About Skagit Design Homes

Skagit Design Homes offers ADU plans as part of their design services, providing clients with a starting point for building an accessory dwelling unit on their property. One of the practical aspects of their plan offerings is the flexibility they allow — adjustments can typically be made to accommodate a client's specific ideas or requirements.

Whether someone is looking to build a detached ADU, a backyard cottage, or another type of secondary dwelling, having a solid plan in place is an important first step in the process. Skagit Design Homes works with clients to tailor plans where possible, helping to align the design with individual needs.

Understanding ADU Size Requirements

It's worth noting that maximum ADU sizes vary by area. Zoning regulations and local building codes differ from one municipality to the next, which means the allowable square footage for an accessory dwelling unit in one location may not apply in another. Skagit Design Homes advises clients to check with their local municipality to confirm the specific size requirements before moving forward with a plan.

This is an important step that any prospective ADU builder or homeowner should take early in the planning process to avoid complications down the line. Local planning departments can provide guidance on what is permitted in a given area.

Working With Skagit Design Homes on Your ADU Project

For those considering an accessory dwelling unit — whether it's a granny flat, an in-law suite, or a backyard cottage — having access to adjustable plans can make the design process more manageable. Skagit Design Homes positions itself as a resource for clients navigating this process, offering plans that can be modified to better fit the homeowner's vision within the constraints of local regulations.

As with any construction project of this nature, working with an experienced ADU contractor and verifying local requirements early are key factors in keeping a project on track.

"We absolutely loved working with Skagit Design Homes! The whole process was easy and fluid. They were very accurate in their predictions on timing, and went above and beyond to get us in our home a little early, just in time for Christmas! The whole team was great and worked with us in customizing our floor plan. They were always very responsive and would get answers to our questions immediately. We love our new home! Thank you Skagit Design Homes!!!"

"Building a home with the Skagit Design Home team was a great experience. We enjoyed the whole process of creating a home on a computer screen into a reality. James, Angel, Jordan, Bart and Carsen communicated each step of the project with clarity. They were available to answer questions and find solutions throughout the project. We are very pleased with the final product. We highly recommend Skagit Design Homes if you are in the market to build an affordable quality home. Rhett Amy Dixon"

"We just finished our first build. The process seemed daunting, but it was wonderful to work with Skagit Design Homes. Being new to the process, we had a lot of questions. The best part for us was the communication, we were always kept informed, and all of our questions were answered in detail and promptly. The house itself looks great and exceeds expectations. We had a great experience and recommend them without a single reservation!"

"Everyone I dealt with was friendly and professional. The build went smoothly and quickly. The work is perfect! They put in upgraded items that I didn't pay for, such as skylight shades that close via remote. I had friends that are professionals in electric, HVAC and plumbing review the work. They said it was great. I really can't be happier with my experience."

"Excellent job when it was all said and done. Like anyone building a house, its never done as quickly as youd like but, the quality of the work that was done is outstanding. We used our own flooring guy and he told me that everything was square which makes his job that much easier and that the quality of the sheetrock and texture was some of the best he has seen. During the initial process my wife worked with Skagit Design and enlarged windows and changed the interior layout to fit our needs. Every subcontractor that arrived on site was professional and did excellent work and went above and beyond. The electrical contractor worked with us adding outlets and anything else we wanted. Plumbing was the same, excellent work. Being in construction for 40yrs, its pretty obvious when subcontractors arent top notch and that certainly wasnt the case. I highly recommend Skagit Design to anyone that is interested in building a new home. Patrick Gould"
