Frequently Asked Questions

A detached ADU, or Accessory Dwelling Unit, is a separate, standalone residential structure that is located on the same property as a primary residence but is not attached to it. These units are also commonly referred to as granny flats, in-law suites, backyard cottages, or secondary dwellings.

Building a detached ADU (Accessory Dwelling Unit) in Miami, as in many other places, can offer several benefits to homeowners and property owners. Here are some of the advantages:

  1. Additional Rental Income: One of the primary benefits of a detached ADU is the potential for rental income. You can rent out the unit to tenants, providing a consistent source of revenue that can help offset mortgage costs or other expenses.
  2. Increased Property Value: Adding a detached ADU can increase the overall value of your property. The additional living space and income potential can make your property more attractive to potential buyers, should you decide to sell in the future.
  3. Multigenerational Living: Detached ADUs are ideal for accommodating family members such as aging parents or adult children. They offer a separate living space while allowing for proximity and care when needed.
  4. Home Office or Studio: A detached ADU can serve as a dedicated home office, art studio, or workspace. It provides separation from the main house, reducing distractions and improving productivity.
  5. Flexibility: Detached ADUs are versatile spaces that can be used for various purposes, from a guest suite to a fitness room or a creative retreat. You have the flexibility to adapt the space to your changing needs.
  6. Privacy: Detached ADUs offer a level of privacy for both you and your tenants or guests. The separate structure allows for independent living while maintaining a sense of separation from the main house.
  7. Local Zoning Regulations: Many areas, including Miami, have updated zoning regulations to encourage ADU construction. This means it may be easier to obtain permits and approvals for building a detached ADU.
  8. Sustainability: Depending on your design choices, detached ADUs can be built with eco-friendly features, such as energy-efficient appliances, solar panels, and sustainable materials, contributing to a more sustainable lifestyle.
  9. Community Benefits: Adding more housing options to a community can help address housing shortages and affordability issues, which can be beneficial for the broader community.
  10. Aging in Place: As homeowners age, a detached ADU can provide a more manageable and accessible living space while allowing them to stay in their familiar neighborhood and close to family.

The requirements for building a detached ADU (Accessory Dwelling Unit) in Miami County, Florida, can vary depending on the specific location within the county and the local zoning regulations. It’s essential to check with the local planning or zoning department for the most up-to-date and accurate information regarding ADU construction in your particular area. However, I can provide some general guidelines that are commonly found in many jurisdictions:

  1. Zoning Regulations: Ensure that your property is located in an area zoned for ADUs or accessory structures. Zoning regulations can vary within Miami County, so it’s crucial to confirm that your property meets the zoning requirements for ADU construction.
  2. Permits: You will typically need to obtain building permits and possibly other permits, such as plumbing and electrical permits, for your detached ADU project. Consult with the local building department to understand the specific permit requirements and application process.
  3. Size and Setbacks: The size and setbacks (required distances between structures and property lines) for detached ADUs can be subject to local regulations. Ensure that your ADU design complies with these requirements.
  4. Parking: Some areas may have specific parking requirements for ADUs. You may need to provide off-street parking spaces for both the primary residence and the ADU. Check with local regulations to determine the parking requirements for your property.
  5. Utilities: Determine how utilities such as water, sewer, electricity, and gas will be connected to the detached ADU. Ensure that your utility connections comply with local utility and building codes.
  6. Design and Safety Codes: Your detached ADU must comply with building codes and safety standards. This includes structural integrity, fire safety, and accessibility requirements.
  7. Architectural Review: In some neighborhoods or historic districts, there may be architectural review boards that need to approve the design and appearance of the ADU to ensure it fits within the character of the area.
  8. Tenant Restrictions: Some areas may have restrictions on who can live in the ADU, such as family members only or no short-term rentals. Be aware of any occupancy restrictions that apply.
  9. Accessibility: Depending on your intended use, you may need to consider accessibility features, such as ramps or wider doorways, to accommodate individuals with disabilities.
  10. Waste and Recycling: Ensure that your detached ADU complies with waste disposal and recycling requirements, including trash pickup schedules and container placement.
  11. Homeowners’ Association (HOA) Rules: If your property is part of an HOA, check the association’s rules and regulations regarding ADU construction. HOAs may have additional restrictions or guidelines.

The cost of building a detached ADU (Accessory Dwelling Unit) in Miami County, Florida, can vary significantly depending on a range of factors, including the size, design, materials, location, and any specific features or amenities you wish to include. It’s important to note that construction costs can also change over time due to fluctuations in the construction industry.

Please keep in mind that these are approximate figures, and actual costs may vary (you can call us for a free estimate):

  1. Basic ADU: A simple, smaller ADU with minimal features and finishes may cost between $120 to $300 per square foot to build. This estimate includes construction materials, labor, and basic fixtures.
  2. Mid-Range ADU: A moderately sized ADU with standard finishes and some amenities, such as a kitchenette and bathroom, might cost between $300 to $400 per square foot.
  3. High-End ADU: A larger, well-appointed ADU with high-end finishes, custom design features, and premium fixtures can cost $400 or more per square foot.
  4. Site Preparation and Utilities: Additional costs may include site preparation, utility connections (water, sewer, electricity), foundation work, landscaping, and driveway or parking area construction.
  5. Architectural and Design Fees: If you hire an ADU builder, their fees will also be a part of the overall cost. If you choose Blue Builder Miami, you can rest assured we have the best prices of all.
  6. Permit and Inspection Fees: Budget for the cost of obtaining necessary permits and scheduling inspections.
  7. Landscaping and Exterior Features: Depending on your preferences, you may want to include landscaping, outdoor living areas, and other exterior features, which will add to the cost.
  8. Customization and Special Features: Any special features like energy-efficient upgrades, smart home technology, or unique design elements will increase the cost.
  9. Present Local Factors: Local building codes, zoning regulations, and the cost of materials in Miami County can also influence the overall cost. This year there are some fees, next year will be modified…

The time it takes to build a detached ADU (Accessory Dwelling Unit) can vary significantly depending on various factors. While some ADUs can be constructed relatively quickly, others may require more time due to design complexity, site-specific considerations, permitting processes, and other variables. Usually, it can take more than 2 months.

Yes, you need to obtain a permit in Miami County to build a detached ADU. The permit process can be complex, so it is important to work with a qualified contractor, such as us – Blue Builder, who is familiar with the local permitting process.

The specific requirements for obtaining a permit to build a detached ADU will vary depending on the municipality in Miami County. However, there are some general requirements that apply to all detached ADUs in Miami County, such as:

  • The ADU must be detached from the main house.
  • The ADU must have its own kitchen and bathroom.
  • The ADU must have its own separate entrance.
  • The ADU must meet all applicable building codes and zoning regulations.

To obtain a permit to build a detached ADU, you will need to submit an application to your local municipality. The application will typically require you to provide plans and specifications for the detached ADU, as well as proof of ownership of the property and payment of a permit fee.

Once you have submitted your application, the municipality will review it to determine if it meets all of the requirements. If your application is approved, you will be issued a permit. You can then begin construction on your detached ADU in Miami.

It is important to note that the permit process can take several weeks or even months, so it is important to start planning your project early. Additionally, it is important to work with a qualified contractor, such as Blue Builder Miami, who is familiar with the local permitting process and can help you obtain all of the necessary permits.

Some of the challenges of building a detached ADU in Miami include:

  • Cost: Detached ADUs can be more expensive to build than attached ADUs, due to the additional costs of grading the land, installing utilities, and constructing a separate driveway and parking area.
  • Permitting: The permitting process for detached ADUs can be more complex and time-consuming than the permitting process for attached ADUs.
  • Zoning: Some municipalities in Miami have zoning regulations that restrict or prohibit the construction of detached ADUs.
  • Setbacks: Detached ADUs are typically required to comply with setback requirements, which means that they must be a certain distance from the property lines. This can limit the size and placement of the ADU.
  • Utilities: Detached ADUs need to be connected to utilities such as water, sewer, electricity, and gas. This can be a challenge, especially if the ADU is located a distance from the main house.
  • Construction: The construction of a detached ADU can be more disruptive to the main house and the surrounding property than the construction of an attached ADU.

The benefits of working with us to build a detached ADU in Miami include:

  • Peace of mind: We will handle all of the aspects of the project, from obtaining the necessary permits to coordinating the construction process.
  • Expertise: We have the necessary skills and experience to build your detached ADU safely and efficiently.
  • Warranty: We offer warranties on our work, so you can be confident that your detached ADU is built to last.

The best time of year to start a detached ADU construction in Miami is during the spring or fall. During these months, the weather is mild and there is less chance of rain delays. Additionally, the spring and fall are typically less busy for contractors, so you may be able to get a better price on your project.

However, it is important to note that the best time to start an ADU construction in Miami can also vary depending on your specific needs and preferences. For example, if you need to move into the ADU by a certain date, you may need to start construction sooner, even if it means dealing with more extreme weather conditions.

Whether an attached or detached ADU is better for you depends on your individual needs and preferences. Here is a comparison of the two types of ADUs:

Attached ADU

  • Pros:
    • More affordable to build
    • Easier to connect to utilities and other infrastructure
    • More convenient for accessing the main house and other amenities
  • Cons:
    • Less privacy for both occupants of the main house and the ADU
    • Can be more disruptive to the main house during construction
    • May have fewer design options due to the need to connect to the main house

Detached ADU

  • Pros:
    • More privacy for both occupants of the main house and the ADU
    • Less disruptive to the main house during construction
    • More design options
  • Cons:
    • More expensive to build
    • More difficult to connect to utilities and other infrastructure
    • Less convenient for accessing the main house and other amenities

If you are looking for a more affordable and convenient ADU, an attached ADU may be a better option for you. However, if you are looking for a more private ADU, a detached ADU may be a better option.
