ADU Tips And Tricks: Tennessee

Updated: August 7, 2024

Thinking about adding an Accessory Dwelling Unit (ADU) to your property in Tennessee? ADUs are gaining popularity as they provide extra living space, potential rental income, and can increase your property's value.

ADUs are built on the same lot as the main house and offer independent living quarters. They're perfect for use as a private retreat, guest house, rental property, or backyard cottage. With their own separate entrance, it's easy to see why homeowners are eager to add them to their properties.

While ADUs are appealing, we understand that the process of building one can be overwhelming. There's a lot to consider, from local regulations and building codes to interior design, budgeting, and the overall planning process.

To help you navigate this process, here are some essential tips for a successful ADU project in Cookeville.

Tip 1: Determine Your ADU's Purpose

Before diving into construction, it's crucial to decide on the ADU's intended use. Take your time with this step, as it requires careful consideration.

Ask yourself:

  • Do you need a separate workspace, like a private office?
  • Are you looking to create an outdoor living space for teenagers, adult children, or other family members?
  • Do you plan to use it as a source of additional income, such as an Airbnb or long-term rental?
  • Will it serve as housing for elderly parents?

Once you've made your decision, it's time to check your zoning permissions.

Check Your Zoning

Tip 2: Verify Zoning Regulations

Since ADUs share the same residential property as the main house, you'll need to consult with Cookeville's local planning department to ensure you can build an ADU on your property.

This step ensures compliance with local zoning laws, International Residential Codes, and property tax regulations. It also helps prevent any legal issues down the road.

Possible ADU zoning restrictions

  • Limits on the number of ADUs per property
  • Distinctions between ADUs and tiny homes on wheels (THOWs)
  • Restrictions on the percentage of property area an ADU can occupy
  • Size limitations (e.g., 300 - 800 square feet)
  • Height restrictions
  • Rules about attached vs. detached ADUs
  • Minimum distance requirements from property lines

Be sure to check with your local authorities for specific regulations in Cookeville and surrounding areas.

To avoid confusion, accessory dwelling units go by various names:

  • Accessory apartments
  • Secondary suites
  • Granny flats
  • Backyard cottages
  • Outhouses

Next, you can begin the planning process.

Planning Is Key

Tip 3: Plan Thoroughly

After obtaining building permission and determining the ADU's purpose, it's time to start planning. This is a crucial step for any successful design. Here's what to consider:

Parking space

ADUs are required to have an off-street designated parking area. However, you may be able to sidestep this regulation if your property complies with one (or more) of the following:

  • It's within half a mile of public transport.
  • A car-share vehicle is located within a block of your property.
  • It's situated in an architecturally and historically significant area.

If these don't apply to you, you'll need to incorporate a parking bay within your ADU design (which complies with building standards).

Accessibility

Since accessory apartments are independent living quarters, they require ample accessibility, such as:

  • An off-street parking bay.
  • A private entrance.
  • A safe pathway to exit the ADU (in the event of a fire) - typically onto a street/safe zone.

Pro tip: Install fire extinguishers and smoke and carbon monoxide alarms to ensure your ADU complies with fire regulations.

Privacy

If the accessory dwelling unit is a rental property, you might want to prioritize privacy. For instance, place the unit's front door facing away from the main house or incorporate screens or hedges to enclose the space. Consider soundproofing insulation - walls, ceilings, doors - to prevent noise between the two buildings.

On the other hand, if the unit is used for family members or aging parents, you might want to position the ADU closer tothe main home for better social interaction.

Review the construction site

Take note of where you'll build the ADU, ensuring the ground is sturdy and suitable for such structures. Check that the area isn't prone to flooding (in lower-lying areas) and that there aren't trees overheard that could cause damage in strong winds.

Pro tip: A professional building contractor can assist you.

Use existing utility connections

It's worth investigating if you can connect your ADU to the main housing utility supply (a.k.a water, gas, and electricity lines). This eliminates the need for separate connections - and additional expenses!

Aesthetics

Ensure your secondary suite matches the existing architectural design and color scheme of the main building to create a seamless and cohesive look.

Durable building materials

Choose long-lasting, durable building materials when planning your design. These items are hard-wearing, made to last, and increase the value of your ADU investment. A few examples include:

  • Concrete
  • Insulating concrete forms
  • Aluminum
  • Bamboo
  • Timber/wood
  • Steel/iron
  • Brick
  • Stone

Sustainability

ADUs are self-contained buildings with a kitchen, bedroom, bathroom, and living space. Consider integrating eco-friendly and energy-efficient features into your ADU design to reduce your carbon footprint.

These include:

  • Solar panels
  • Water tanks
  • Proper insulation
  • Energy-efficient windows and doors
  • Energy saving appliances
  • LED bulbs
  • Maximize natural light (e.g. skylights, stack-away doors, large windows)

Depending on your style preference, use ethically sourced timber, recycled steel, and natural stone building materials. Not only are these elements visually appealing, but they're kind to the planet as well!

Knowing the basic layout and the elements you want to use, you can now set your budget.

Tip 4: Set a Realistic Budget

Budgeting is crucial for keeping your project on track financially. The average cost of building an ADU can range from $60,000 to $225,000.

Some budgeting tips:

  • Review your finances to determine your maximum spend. This amount must include labor and construction fees, plumbing, electrical, building materials, appliances, paint, lighting, and planning permit costs.
  • Allocate your budget for each part of the construction project. For instance, set X aside for building, Y for interiors, and Z for landscaping. Prioritize the most important things first, like good quality materials, roofing, flooring, appliances, and cabinets, before you purchase less expensive items like paint, light fittings, and plants.
  • Get quotes from various local contractors, plumbers, electricians, and interior designers. This will help you negotiate better deals. Consider Cookeville Home Remodeling for the best prices in Tennessee.
  • Keep track of your expenses throughout the entire process using notebooks, emails, spreadsheets, or budget-tracking apps. This ensures you are always within range.

Pro tip: Set aside a buffer of around 5% - 10% of your budget for unforeseen expenses.

Now that the most important considerations are out of the way, you can start designing your perfect ADU!

Begin The Design Process

Tip 5: Begin The Design Process

rafting ADUs that blend aesthetics, functionality, and adaptability is no small feat. You'll need to work within the confines of your existing space, which can be challenging if your backyard has an unusual shape. Additionally, you must consider the unit's dimensions and what you're allowed to construct according to local regulations.

When it comes to secondary suites, maximizing space is paramount, regardless of whether you're building attached ADUs (connected to the main house) or detached units (standalone structures).

Here are our recommendations:

Multi-functional furniture

Opt for furniture that serves multiple purposes. Consider items like storage ottomans, breakfast nooks with hidden compartments, kitchen islands featuring extra drawers and shelves, toe-kick drawers, or adaptable dining tables that double as workstations.

Adequate storage

Building on the previous point, ensure every item has its designated place within your auxiliary unit. Overflowing cabinets and cluttered countertops can make a space feel cramped. Install ample storage options and make use of vertical space to avoid this issue. For instance:

  • Floor-to-ceiling cabinets
  • Vertical shelving units
  • Suspended pot racks
  • Narrow pantry
  • Murphy bed
  • Daybed/futon

Open concept layout

Think about implementing an open floor plan to create an illusion of spaciousness. Utilize area rugs, strategic furniture placement, or room dividers to delineate specific zones such as the living area, sleeping quarters, or kitchenette.

Expert design suggestions:

  • Choose light hues for the ADU's main surfaces - walls, floors, ceilings, cabinetry, countertops - to enhance the sense of space and brightness.
  • Expand the outdoor living area with a compact patio or deck.

Barn doors

Think about installing sliding barn doors that glide along a track instead of traditional swinging doors. This eliminates the need for clearance space. Another option is to use shower curtains or walk-in showers in tight bathrooms rather than enclosed units.

Compact appliances

Look into smaller, energy-efficient appliances. Multifunctional appliances, like washer/dryer combos, can save space while maintaining functionality.

By incorporating these design concepts, you can create a cozy and practical ADU on your Tennessee property, all while adhering to size restrictions!

10 Common ADU Project Pitfalls (And How To Sidestep Them)

Here are several frequent accessory dwelling unit mistakes and ways to avoid them:

  1. Misaligning the ADU's purpose and design: Think carefully about the unit's intended use and plan accordingly. Don't expect tenants to comfortably inhabit a space designed as a home office.
  2. Overlooking zoning requirements: Always verify local ADU regulations before commencing any construction on your property.
  3. Ignoring building codes: Seek expert guidance when planning an ADU project. Non-compliance with building regulations can result in substantial fines and wasted resources.
  4. Poor measurements and planning: Accurate measurements and thorough planning ensure all furnishings and appliances fit comfortably within your secondary suite.
  5. Underestimating costs: Don't misjudge the project's scope. Establish a realistic budget that covers all expenses, from construction and plumbing to decor and lighting fixtures.
  6. Inadequate soundproofing: Ensure sufficient insulation and noise reduction measures to minimize sound transfer between the main house and ADU.
  7. Neglecting storage needs: Maximize vertical space to create ample storage solutions.
  8. Cutting corners on labor, materials, and finishes: Taking shortcuts may save money initially but could lead to higher costs for repairs or replacements in the near future.
  9. Avoiding expert assistance: Reputable, licensed building professionals are skilled at handling complex ADU tasks. They possess the knowledge and expertise to ensure a smooth, code-compliant secondary apartment construction.
  10. Following fleeting trends: Fads quickly become outdated. Choose a neutral color palette for floors, walls, and cabinetry to ensure a timeless design.
