Does Your Sarasota Home Need an ADU?

What Is an ADU?

First things first: let's get on the same page about ADUs.

Are ADUs allowed in Florida? Yes! However, zoning laws vary by city and county, so checking local regulations is an important first step.

What Are the Different Types of ADUs?

The type of ADU will depend on the space you have available on your property or in your home. Here’s a breakdown of the different types to consider for your ADU construction project:

1. Detached New Construction ADU

A detached ADU is a stand-alone unit separate from the main home. This is the most private type of ADU, offering a fully functional living space, often including a kitchen, bathroom, and bedroom.

These structures are perfect for guest houses, rental units, or a quiet home office. 

2. Garage Conversion ADU

Transforming an existing garage into an ADU is a cost-effective solution that maximizes your home’s existing footprint. This type of conversion can be a great option if you don't want to give up yard space.

Depending on local zoning, ADU costs for garage conversions can be lower than building a detached unit from scratch. 

3. Attic Conversion ADU

If you have an attic that doesn't get much use, converting it into an ADU can be a smart way to maximize space without expanding your home’s footprint.

An attic ADU can function as a fully independent living space with a kitchenette, bathroom, and sleeping area. Its use will depend on how much space you have.

If your attic is on the smaller side, it can be used for weekend guests or an office. Have more comfortable square footage available? With the right features, you can house an older relative long-term or welcome back your college-aged kid.

4. Attached ADU

An attached ADU is an expansion or addition to your home with a separate entrance and possibly even a separate driveway, parking spot, and maybe an outdoor hangout area if space allows.

Building an attached ADU means you can extend electrical, plumbing, and HVAC systems more easily, possibly without having to increase capacity. However, you'll want to check with your contractor to see if this is an option. 

This setup is ideal for multi-generational living, especially if safety is a concern, or long-term rental opportunities if your addition checks the legal boxes.

Why Do People Build ADUs on Their Sarasota Property?

Homeowners have plenty of reasons to build an ADU. If you're on the fence, check out these common reasons to see where you fit in: 

• Space for guests: If you frequently have out-of-town weekend guests or host family during the holidays, building an ADU makes it easier to accommodate them without the stress of sharing space in your main home.
• A dwelling for an adult child: Multi-generational homes are more common than ever. With a second house on your property, your adult child can live with you while still enjoying their independence.
• Age in place for an older relative: An ADU is a perfect place for an older relative who wants to live independently but still needs help from time to time. If this sounds like your situation, be sure to talk to your team about adding accessibility features to ensure their safety and comfort. 

A well-built, well-designed ADU gives you the flexibility to grow and expand your household without having to go through the headaches of moving. If you have a need for extra space – more than just a simple addition – then an ADU might be for you.

What Features Should You Include In Your ADU?

Plan your ADU with the features you need rather than some cookie-cutter plan that could fall short of your needs and wants.

Here are a few recommendations you should consider for your unique design: 

Aging in Place Design

You could be planning your ADU in advance of an older loved one moving in, or maybe you just want to be prepared for the "what ifs."

Universal design is a style of construction that means it'll be accessible for people with disabilities, seniors, and people with special needs. Wide hallways, wide doorways, ramps, easy-to-grasp knobs and switches, and grab bars are the most common features.

Smart Home Features

Smart home features are being integrated more and more into homes nowadays. Chances are, you might already have a few in your home. Voice assistants, smart thermostats, and smart security systems are a few of the most common that can add convenience, safety, and energy efficiency to your ADU. 

If accessibility and safety are your goals, choose smart appliances and motion-sensor lighting, too. Smart stoves, touchless faucets, and scald-proof showers are perfect additions as well.  

Outdoor Living Spaces

A small porch or patio is a little something special to give whoever's staying in your ADU, whether they're staying just for the weekend or long term. Include comfortable seating, privacy partitions, and landscaping to create a cozy setting for morning coffee, an afternoon book, or a glass of wine in the evening. 

What to Know Before Building an ADU in Florida

Thinking about adding an ADU to your property? From zoning rules to privacy and utilities, here’s what to consider right at the start of your planning process.

Check Zoning and Building Requirements

Before diving into ADU construction, make sure your property qualifies. Local zoning laws vary, so check Sarasota County tiny house rules and building codes to see what’s allowed. Some important factors include:

• Maximum structure height and size
• Utility easements and setbacks
• Parking requirements
• Occupancy limits

Skipping this step could lead to costly delays, so it’s best to confirm everything upfront.

Think About Accessibility and Privacy

Your ADU should have a separate entrance and can also include a private walkway, fencing, or landscaping.

If the space is for family, consider how much privacy they’ll want. Small details—like soundproofing between walls for attached ADUs—can make a big difference in comfort.

Also, think about outdoor access—will the unit have its own patio or yard space, or will it share common areas? The goal is to create a setup that feels like a true independent space.

Sort Out Utilities Early

Can your ADU tap into existing utility connections, or will you need to install new ones? This will impact ADU costs and the project timeline but could be a very necessary factor.

Your contractor can help you determine the best solution based on your home’s layout and local regulations. Water, electricity, and sewer connections should be planned ahead of time to avoid unexpected expenses. You may also have to consider separate utility meters if your ADU will be used as a rental.

Hire the Right Contractor

Finding the right contractor for your ADU construction is a major part of your planning process. Look for someone experienced with Sarasota County building setbacks and permitting requirements. The right contractor will:

• Help navigate zoning and approvals

• Provide realistic cost estimates

• Offer design solutions that maximize space

Ask about their experience with ADUs specifically since these projects tend to have unique challenges compared to traditional home additions. 

Plan for the Future

If your ADU is for an aging relative, consider their long-term needs.

Features like no-step entries, wider doorways, and easy-to-maintain materials can make the space far more comfortable. Even if it’s a rental or guest house, thoughtful planning now can save you from expensive updates later.

Can I Build an ADU on My Florida Property?

Building an ADU in Florida is an exciting way to add living space, but before you break ground, know that zoning laws could affect your design.

Many homeowners assume they can build a small structure—like a guest house or detached living space—only to find out later that zoning regulations will make it a no-go. This mistake can lead to costly fines, delays, or even the removal of the structure altogether. 

Check Sarasota County Zoning Laws

Before starting ADU construction, research Sarasota County tiny house rules and zoning codes for your specific neighborhood. Zoning laws regulate land use, ensuring that residential areas remain distinct from commercial developments. These regulations help prevent disruptive changes, such as a neighbor turning their home into a business or rental property that isn’t permitted.

How to Find Out If ADUs Are Allowed

To determine whether ADUs are allowed in Florida and specifically in your area, start by checking your city’s zoning maps, often available on local government websites. If you can’t find the information online, you can request zoning details from the county office. This public record should include:

• Property zoning classification
• ADU building restrictions and setbacks
• Parcel number and legal property description

Keep in Mind That Zoning Laws Can Change

Even if you’ve checked zoning laws before, they may have changed since your last review. Local governments update zoning regulations periodically, sometimes without major public announcements.

Before moving forward with ADU construction, confirm that the rules are still the same and consult your ADU contractor to ensure compliance.

Building an ADU is a great investment, but zoning laws can make or break your project. Doing your homework now can save you from major headaches down the road.

Is Adding an ADU Worth It?

If anything we've included in this article so far resonates with you, an ADU is totally worth it. It's a flexible living space, potential rental income, and a cost-effective alternative to moving. 

Besides adding value to your property, an ADU addition just makes life easier than cramming 

Whether you’re accommodating aging parents, providing space for adult children, or planning for a future rental, an ADU can add significant value to your home.

How Often Will You Use the ADU?

This is an important aspect to think about. One of the biggest factors in determining whether an ADU construction project is worth it is how often it will be used.

If you're using it as your everyday office, as a rental unit, for frequent guests, or multi-generational living, you'll be so glad you decided to move forward with this kind of addition. 

Financing Options for Your ADU

If you have home equity, refinancing could provide the cash needed for ADU construction. There are also renovation loans available that may help cover costs. Just keep in mind that if your property needs to be rezoned to accommodate the ADU, additional fees may come into play.

This is where getting financial entity recommendations from your builder will come in handy. Ask them for a few that they trust and have a good track record with. 

Maximizing Your Investment

At the end of the day, an ADU is only worth it if it serves your long-term needs. If it ends up empty, it could feel like a wasted expense.

However, many homeowners choose to rent out their ADU when it’s no longer needed for family, turning it into a source of passive income. Whether you plan to use it for years or want a flexible living space that can adapt over time, an ADU can be a great addition—if thoughtfully planned.
