Accessory Dwelling Units, or ADUs, are changing the game for homeowners who want to make better use of their space or boost their property value. Whether it’s a cozy backyard cottage or a revamped basement, ADUs are popping up all over the U.S.—and it’s easy to see why!
These small but mighty spaces offer tons of flexibility, extra income potential, and even help tackle housing shortages. If you’re curious about this growing trend, this guide will walk you through what an ADU is, the benefits it brings, and why adding one could be the smartest move for your home.
What is an ADU?
ADUs are cozy, self-contained living spaces built right on the same property as a single-family home. Think of them as mini homes with their own entrance, kitchen, bathroom, and living area, all packed into a compact and efficient design. They’ve been around for a while in forms like carriage or coach houses, but today they’re all about modern living, combining style with practicality.
Even though they’re smaller than the main house, ADUs offer everything you need for comfortable living, along with plenty of privacy. They’re super versatile too—perfect for housing a family member, hosting guests, or even renting out for some extra income.
Types of ADUs
There are several types of ADUs, each catering to specific property sizes and goals. Here’s a breakdown:
Detached ADU
Think of this as a separate little home, like a backyard cottage or an apartment above your garage. While you’ll need to set up separate utilities (like plumbing and electricity), these offer the most privacy for both you and the people living there.
Attached ADU
These are built as extensions of your main home, sharing at least one wall but with their own entrance for independence. They’re a budget-friendly option since they often use the same utility connections as the main house.
Interior ADU
Interior ADUs are created within your existing home—think basement, attic, or even repurposing part of your current living space. They’re great for making the most of what you already have and are usually the most affordable option to build since they require fewer structural changes.
Junior ADU (JADU)
A Junior ADU, or JADU, is a smaller version of an ADU, capped at 500 square feet. It’s always attached to or inside the main house and might even share a bathroom with the primary residence.
Each type of ADU has its own perks, depending on what you’re looking to achieve—whether it’s boosting your property value, earning extra rental income, or creating space for family.
Benefits of ADUs
Why are so many homeowners investing in ADUs? Here are the key benefits you should consider:
Financial Benefits
- Earn Extra Income: Adding an ADU can turn your property into a steady source of passive income. Rent it out to long-term tenants or even list it on Airbnb for short-term stays. According to Homes.com, many homeowners use this additional income to help cover mortgage payments and other expenses.
- Boost Your Property Value: Adding an ADU is a smart way to increase your home’s market value. With more usable space and added functionality, homes with ADUs are super appealing to buyers.
Family Benefits
- A Space for Loved Ones: ADUs are ideal for aging parents, young adults, or extended family members. They provide independence and privacy while keeping everyone close. In fact, an AARP study shows many homeowners build ADUs specifically for family use.
- Versatility at Its Best: Use your ADU as a guesthouse, an office, or even a personal gym. These spaces grow and adapt with your changing needs.
Community Benefits
- Affordable Housing Options: ADUs offer smaller, more affordable homes, increasing housing variety and helping to address the housing shortage.
- Better Neighborhoods: ADUs add living space to neighborhoods without changing their charm, making great use of existing lots.
Regulations and Zoning in Idaho
Understanding the local regulations around building ADUs is key before starting any construction. Laws about ADUs vary widely by state, and Idaho has been actively encouraging ADU construction to tackle local housing challenges.
Idaho’s Approach to ADUs
Newly updated regulations in areas like Coeur d’Alene, Hayden, and Post Falls are making it easier than ever to build ADUs. These small, secondary homes are becoming a popular way to create more affordable housing while keeping communities connected.
With initiatives like pre-approved ADU plans (which make the permit process a breeze) and support from The Housing Solutions Partnership, Idaho homeowners now have access to resources that make building an ADU simpler and faster.
The pre-approved plans feature energy-efficient designs up to 800 sq. ft., saving you money on production costs and cutting down construction time. These updates are putting Idaho on the map as a great place to build ADUs!
