🏡 What Is an ADU and Why It’s a Smart Move for Cape Cod Homeowners

Accessory Dwelling Units (ADUs) are transforming the way Cape Cod homeowners think about space, lifestyle, and long-term value. Whether you call it a guest house, in-law suite, or backyard cottage, building an ADU can increase flexibility, support family, and unlock the hidden potential of your property.

Let’s explore what ADUs are, why they’re trending on the Cape, and how Capizzi Home Improvement can help you bring one to life.

🔍 What Exactly Is an ADU?

An Accessory Dwelling Unit (ADU) is a self-contained residential space on the same property as your main home. It has its own entrance, kitchen, bathroom, and living area—and it’s designed to function independently from the main house.

Common ADU Types on Cape Cod:

• 🛖 Detached ADU – A freestanding unit in your backyard

• 🧱 Attached ADU – An addition connected to your existing house

• 🚗 Garage Conversion – Repurpose your garage as living space

• 🏠 Above-Garage Apartment – Add a second-story rental or suite

• 🔽 Basement ADU – Convert lower-level space into a private unit

• 🔼 Upper-Level ADU – Finish your attic into a livable flat

💡 Why Homeowners on Cape Cod Are Building ADUs

💰 1. Boost Your Property Value

An ADU can significantly increase your home’s appraised value. With Cape Cod’s limited housing inventory, homes with an ADU are especially attractive to buyers looking for multi-functional properties.

💸 2. Earn Passive Rental Income

Looking to generate steady income? An ADU can serve as a long-term rental or seasonal vacation unit, providing you with ongoing financial benefits—while remaining compliant with local regulations.

👨‍👩‍👧 3. Support Multigenerational Living

Cape Cod families are increasingly living together across generations. Whether for aging parents, adult children, or visiting relatives, an ADU provides privacy and comfort—without giving up proximity.

🖥️ 4. Add Flexible, Functional Space

Need a quiet home office? A space for hobbies? A guest suite? An ADU gives you freedom to expand your lifestyle—without sacrificing rooms in your main house.

📍 What You Need to Know Before You Build

🗂️ Cape Cod Zoning Regulations Vary

Every town on Cape Cod has its own zoning bylaws for ADUs. Some allow detached units, while others may limit ADUs to interior conversions or attached additions. Key factors include:

• Minimum lot size

• Setbacks and coverage rules

• Maximum square footage

• Owner occupancy requirements

• Rules for short-term vs. long-term rentals
