ADU – Accessory Dwelling Units

ADU - Accessory Dwelling Unit

Attractive ADUs in Seattle

Do you have a dependent family member whose health needs require you to attend to them daily and remain close by? Or perhaps you have an older child who needs a place to stay but requires their own space. Maybe you’re just interested in gaining a passive income by becoming a landlord. If any of these situations apply to you, then it might be time to invest in an accessory dwelling unit. 

ADUs, also referred to as granny flats, in-law suites, and lane houses, are small dwellings that are located on the same property as the main residence. They usually have their own bathroom and kitchen. If they are not attached to the main residence, they may even have their own plumbing, electrical, and HVAC systems. They are an excellent investment for those who want to keep reliant family members nearby or start a rental business.

One of the main benefits of ADUs is their ability to provide additional housing options within existing neighborhoods without significantly altering the character of the area. They offer an opportunity for homeowners to create additional living space for family members, guests, or tenants, while also providing an extra source of rental income. ADUs can be an attractive option for multi-generational families, allowing older adults to age in place while maintaining their independence and close proximity to their loved ones.


Will you help me obtain permits for my Accessory Dwelling Unite?

Yes, of course. We can help you handle all the necessary credentials, permits, and paperwork that you will need. Our team has been working in the construction industry for years, and assisting in this area is nothing new to us. 

Are there specific requirements for my ADU’s size?

Every state has different requirements that limit how large an accessory dwelling unit can be. In Seattle, it can measure a max of 1,000 square feet. We will help you determine what size you are allowed to have on your property.

What are the different types of ADUs?

There are several different types of ADUs. Attached accessory dwelling units are part of the main residence, and they share the same electrical, plumbing, and HVAC systems. Detached accessory dwelling units stand apart from the main dwelling. They have their own independent entrances and HVAC, plumbing, and electrical systems. Then there are garage and room conversion units, which are created by transforming old space into something new. Junior accessory dwelling units are the last type; these are miniature versions of regular ADUs. They measure a max of 500 square feet and usually lack a full kitchen and bathroom. 

How long does it take to build an ADU?

It can take between eight and 12 months to complete an ADU. It depends on the size and the scope of your project. We’ll be able to give you a more accurate time estimate once we know a little bit more about your specific project.

How much does an ADU cost?

Once again, it is impossible to give you an estimate without knowing more about your project. Costs vary. Some materials are pricier than others, and the costs vary depending on the economy. If you want a specific number, contact us with details about your project for an estimate.
