Accessory Dwelling Units

What Are ADU'S?
If you’re looking into accessory dwelling unit construction, you’re likely eager to learn what this type of build is. Simply put, an accessory dwelling unit or ADU is an independent living space on the same property as a primary home. These spaces typically include their own kitchen, bathroom, sleeping area, and separate entrance.
An ADU can be an attached or detached unit. To determine whether it can be attached or detached or for any other questions on what you can do, it would be best to contact Sunwood Development to discuss any requirements that may be needed for your town or city in Connecticut.
The number of accessory dwelling unit (ADU) permits issued in Connecticut has significantly increased recently, with an 88% growth rate between 2019 and 2022. This statistic indicates that more homeowners are considering building ADUs on their property to meet their growing needs and preferences.
At Sunwood, we understand the need for ADUs and have spent the last few years helping individuals achieve their ADU dreams. As premier home builders and remodelers, we have the experience to provide stellar ADU construction services in Connecticut.
Who Should Consider An ADU?
ADUs are ideal for homeowners looking to:
-
Keep family members close while ensuring privacy.
-
Supplement their income with a rental unit.
-
Increase the usable space on their property.
-
Create a dedicated workspace or guest suite.
-
Plan for future aging-in-place needs with accessible design features.
Note: The type of ADU you can build depends on local zoning regulations. Thanks to recent changes under Connecticut Public Act 21-29, many towns have revised their zoning codes to allow more flexibility in ADU construction. Before beginning construction, we assess your property and ensure it complies with the specific requirements of your town or city in Connecticut.

What Are The Benefits Of ADU
Multi-Generational Living
An ADU can provide you and your family with a comfortable space for adult children or an aging parent to live while they maintain their and your privacy.Rental Income
With an ADU, whether attached or detached, you can earn passive income by renting it out to tenants. This can help offset mortgage costs on your primary residence.
Increased Property Value
As you might expect, adding a well-designed ADU to your property can help boost your home's market appeal and long-term resale value.
Flexible Living Arrangements
ADUs offer flexible living arrangements since you can have one built specifically for your purposes, whether it be a home office, guest house, mother-in-law suite, or private retreat.
Types Of ADU We Offer
At Sunwood, we provide various ADU solutions tailored to different needs and property layouts. Some of the ADU building services in Durham and surrounding areas we offer include:
-
Father-in-Law and Mother-in-Law Suite Construction: These ADUs are perfect for aging parents who want to maintain independence while staying close to family. However, you should avoid a few mistakes when building this type of ADU. Check out our blog here to learn how to avoid them.
-
Second-Story Additions: With this type of ADU, you can utilize vertical space by adding an independent living unit above an existing structure. It's perfect for those who don’t have space to expand outward but who want a fully self-contained living space.
-
Interior Conversion ADUs: Sometimes, you don’t need to build an entirely separate space when enlisting ADU construction services in Meriden and surrounding CT areas. Instead, you can convert an underutilized section of your home into a fully independent private living space with a separate entrance.
-
Detached ADUs: If your main reason for building an ADU is to generate rental income or have a home for someone you love, you can consider a detached ADU. These standalone units function as a full residence, offering complete privacy from the main home.
-
Attached ADUs: If you don’t want to build a wholly separate unit, you can consider an attached ADU. These extensions connect to the primary home but often have a separate entrance to maintain independence. Most people choose this type when they want a separate living space connected to the main home, such as a basement apartment or an addition with its own kitchen, bath, and entrance
-
Garage Conversions: With a well-built garage conversion, you can turn an existing garage into a comfortable and functional living space. However, a detached garage may or may not qualify as an ADU depending on local zoning and codes.
An ADU That Feels Like Home: Heather & Chris’s Family-Focused Transformation
Heather and Chris needed a comfortable space for their mother, so we helped them create an in-law suite by attaching an ADU to their existing garage. It turned out beautifully, and they were thrilled with the result. Projects like these are a great solution for families needing extra space for parents, adult children, or guests. It’s something we’re proud to offer here at Sunwood.

ADU FAQS
Do I need a permit to build an ADU in Connecticut?
Yes. Connecticut municipalities have specific zoning laws regarding ADUs, including size restrictions and occupancy rules. As we mentioned above, our building team will guide you through the permitting process.
Can I rent out my ADU in Connecticut?
Many towns allow ADU rentals, but some require owner occupancy on the property. We help you understand local regulations before proceeding.
If I build an ADU for a parent, what happens after they pass? Can I rent it out?
Most cities and towns will allow you to rent an ADU that used to belong to a parent after they have passed as long as an owner is living in a part of the home, and no, it doesn’t have to be a relative. However, regulations vary by town, so we always confirm with local zoning before moving forward.
How long does it take to build an ADU?
The timeline depends on design complexity and permitting requirements. On average, it takes anywhere between 6 to 12 months from planning to completion.

Upon completion of the final walk through, I was handed a check for over $700.00, because they completed the work under budget. I moved back into an essentially brand new home. It's been a few years, and the workmanship and materials have held up extremely well. Obviously, I strongly recommend Sunwood Development for your construction needs.
