Pre-Approved DADU Plans

Our Pre-approved DADU Plans, Tailored to Your Needs

Urban Cottage has 4 unique prefab plans for detached accessory dwelling units (DADU) available for purchase. Each of our prefab plans are pre-approved by the City of Seattle.

What does pre-approval from the city mean to you? It means less time spent obtaining a permit, required by the city to build a DADU on your property. The city’s construction addition / alteration permit application requires a complete, code-compliant plan submittal package that must be reviewed and accepted by the city before building can begin. With standard DADU drawings, this review process typically takes 3 to 6 months.

With a pre-approved plan, however, you can cut down wait time dramatically — obtaining a permit in just a few weeks. The city has already assessed and approved all standard aspects of our pre-approved drawings, leaving them with only your unique foundation and site plan to review. Savings in time and costs for all involved!

Studio DADU + Shed Roof
$1,250

The perfect starting point for smaller yards, our studio dwelling unit boasts a living room, kitchen, and bathroom in just 288 square feet of space. If you ever decide to expand your cottage in the future, this adaptable base model can be scaled up to assume a one-bedroom layout.

The studio unit is also unique in that it can be easily configured to accommodate a variety of architectural styles, offering a choice between a shed or gable roof to match the look of surrounding homes. The studio unit + shed roof affords a more modern appearance, complementing the Northwest Contemporary Minimalist and Mid-century Modern styles often seen around Seattle. With an expanse of clerestory windows, the modern shed roof fills the unit with natural light while protecting the privacy of both cottage and primary residents.

 

*All prices include rights to the drawings and the SIPs engineering plan, enabling customers to build a single DADU with each drawing purchase.

All configurations, however, feature a modern shed roof with an expanse of clerestory windows, filling the unit with natural light without compromising the privacy of its residents.
