Haas Development and Construction

Smaller projects may sometimes be quoted remotely using detailed photos and project information. Larger or more complex work generally requires an on-site walkthrough so our team can fully understand the property and scope.

We aim to provide an accurate and fair quote within 48 to 72 hours, although complex projects may require additional time.

Many Seattle properties can accommodate a DADU, but every site is different. Lot size, setbacks, trees, slope, soil conditions, existing structures, and overall property configuration can affect what is possible.

If you're wondering whether your property can accommodate a DADU, Haas can evaluate your site and help you understand your options before you move forward. A professional property assessment is the best way to understand your options.

The best cabinetry is designed around how you actually live. Custom storage can reflect the way you cook, work, entertain, organize, and move through your home. When every cabinet has a purpose, everyday routines can feel easier and more efficient.

Thinking about adding an ADU or DADU to your property? Whether you're creating space for family, generating rental income, or increasing your home's value, Haas Development & Construction is here to guide you every step of the way.

From property assessments and planning to pre-approved DADU floor plans, custom design, engineering, permitting, and construction, our team provides end-to-end solutions tailored to your goals. We make the process straightforward so you can focus on the possibilities.

An accessory dwelling unit, or ADU, is a secondary living space located on the same property as a primary home. An attached ADU is connected to or located inside the existing home, while a detached ADU, or DADU, is a separate backyard structure. Both can create flexible new living space without purchasing another property.

MADE IN SEATTLE. 🛠️ Haas custom cabinetry is handcrafted in our Fremont cabinet shop by a team with more than 30 years of woodworking experience. Every piece is built with careful attention to function, fit, and finish. It is local craftsmanship designed specifically for your home.

Stock cabinets are made to fit standard spaces, while custom cabinetry is designed around the exact dimensions and needs of your home. Custom solutions can maximize unusual layouts, improve storage, coordinate with your home’s style, and make use of every available inch. The result is cabinetry that feels intentional rather than simply installed.

A full-service remodel brings design, permitting, construction, plumbing, electrical, flooring, cabinetry, and finishes together under one experienced team. Haas Development & Construction helps coordinate every phase so homeowners do not have to manage multiple contractors on their own. From the first idea to the final detail, we keep the process moving.

Custom build-ins and woodwork is our bread and butter. Let's take your living space to the next level.
