Accessory Dwelling Units for More Space

At Upgrade Handyman Service, we build Accessory Dwelling Units for homeowners who need more usable space without leaving the home they love. An ADU can give you a private place for family, a comfortable guest suite, space for a caregiver, or a way to create rental income. We focus on well-built, code-aware projects that add function, privacy, and long-term value to your property.

We are a veteran-owned company based in Spencer, MA, and we work with residential homeowners across Worcester County and surrounding towns. Since 2017, we have built our name on professional service, honest pricing, and solid craftsmanship. We are not the cheapest option, and that is by design. ADUs are major construction projects, and they need to be planned and built the right way from the start.

What an ADU can do for your home

An accessory dwelling unit is a separate living space located on the same property as your main home. Depending on your layout and local requirements, an ADU may be attached to the house, created within existing space, or designed as a detached structure. Many homeowners come to us because they want more flexibility from their property without the cost and stress of moving.

• Private living space for parents, adult children, or extended family
• Guest accommodations with better comfort and privacy
• Rental potential to help offset mortgage or housing costs
• Room for a home office, studio, or live-work setup
• Added resale appeal for buyers looking for multi-generational living options

Our ADU service includes

Every property is different, so we tailor the project to your goals, lot conditions, and budget. We can help with the construction side of the project and guide you through what the build may involve. ADU work often overlaps with full remodeling and space conversion, which fits well with our experience in larger residential projects like kitchens, bathrooms, and basement finishing.

Typical ADU work may include:

• Site review and on-site estimate
• Planning the layout for sleeping, living, kitchen, and bath areas
• Framing and structural carpentry
• Insulation and energy-efficiency upgrades
• Window and door installation
• Interior trim, flooring, and finish carpentry
• Kitchen and bathroom build-outs
• Basement or garage conversions when appropriate
• Attached or detached backyard living space construction
• General coordination to help move the project from estimate to build

Built for comfort, privacy, and everyday use

A good ADU should feel like a real home, not an afterthought. We pay close attention to layout, storage, natural light, traffic flow, and the small details that improve daily living. That includes clean finish work, practical room sizes, durable materials, and smart use of every square foot. We also understand the importance of privacy for both the main house and the new living space.

Because the owner spent about 10 years as a nurse before starting this business, we bring a practical, people-first mindset to the work. That matters on ADU projects, especially when the new space is meant for aging parents, recovering family members, caregivers, or multi-generational households. We think about comfort, access, safety, and ease of use, not just appearance.

Code, licensing, and professional standards

ADUs are not simple handyman jobs. They are serious residential construction projects that need proper oversight. We hold a Massachusetts Construction Supervisor License and Massachusetts Home Improvement Contractor registration. We also bring energy and code knowledge through RESNET HERS, IECC/HERS compliance, and ICC residential energy inspection and plan review credentials. That background helps us build spaces that are more efficient, more comfortable, and more aligned with current residential standards.

Licenses include:

• MA Construction Supervisor License #CS-123332
• MA HIC #207347

How our process works

Most ADU projects start with an on-site estimate so we can see the property, understand your goals, and talk through the best path forward. We do on-site estimates for most projects because these larger builds need real measurements and real discussion. Once the scope is approved, we collect a 30% deposit up front, which is the Massachusetts state limit, and then schedule the job.

During the project, we focus on communication, scheduling, and respect for your home. We show up when we say we will, keep the work area as clean as possible, and aim to get the job done right the first time. If your ADU is being built as part of a larger remodel, we can also help align that work with related upgrades to kitchens, baths, windows, doors, or finished lower-level spaces.

Why homeowners choose us for ADU projects

Homeowners call us when they want more than a quick patch job. They want a contractor who takes the project seriously and treats the home with respect. We are a small, owner-led company, which means you get direct communication and accountability from start to finish.
