Frequently Asked Questions

Got questions about pool renovations? We’ve got answers! Here are some of the most common inquiries we receive from homeowners looking to transform their spaces.

  • What’s the difference between an ADU, a granny flat, and a garage apartment?

    While they go by different names, all three generally fall under the category of Accessory Dwelling Units (ADUs). A granny flat usually refers to a ground-level unit built for aging parents or relatives. A garage apartment is either a converted garage or a new unit built above it. The key is that all of these units are self-contained living spaces on the same property as a primary home — including their own entrance, kitchen, bathroom, and sleeping area. No matter what term you use, our team ensures your unit meets all zoning, design, and safety requirements.

  • Can I convert my existing garage into a livable unit?

    Yes — garage conversions are a popular and efficient way to create an ADU without expanding your home’s footprint. We handle the structural changes, insulation, plumbing, and electrical work needed to meet code. We’ll also help you ensure the converted garage has its own kitchen and bathroom, proper ceiling height, and safe egress — all required for it to be classified as a legal, habitable space in Bradenton or Manatee County.

  • What are the permitting requirements for building an Accessory Dwelling Unit in Bradenton?

    Bradenton and Manatee County both require that ADUs meet specific zoning rules related to lot size, unit size, parking, and setbacks. Before starting, we review your property’s zoning designation and confirm whether a detached, attached, or interior ADU is allowed. Once the plan is finalized, we handle the entire permitting process, including building plans, architectural drawings, and coordination with local development offices. Our goal is to make the process smooth and worry-free from start to finish.

  • Can I rent out my ADU for extra income?

    Yes, long-term rentals are typically allowed in Bradenton if your ADU meets all safety and zoning codes. However, short-term rentals (like Airbnb) may be subject to additional restrictions depending on your zoning, HOA rules, or whether you live within the city limits or unincorporated Manatee County. We help you evaluate the potential use of your ADU and can design the space to appeal to either monthly tenants or multigenerational family use, depending on your goals.

  • What’s the maximum size for an ADU in Bradenton?

    The size limit for ADUs typically depends on your lot size, local zoning rules, and the size of your main home. In many areas, detached ADUs are allowed up to 750 to 1,000 square feet, or a percentage of the primary residence’s size (such as 50%). When converting existing space like a garage or attic, square footage must meet minimum room size, ventilation, and ceiling height requirements. We confirm your property’s limits during our initial site visit and design accordingly.

  • Do I need separate utilities for an ADU?

    In most cases, separate utility meters are not required, although they can be added if you want independent billing for tenants. ADUs typically tie into the main home’s electric, water, and sewer systems — something we account for during the design and permitting stages. We’ll coordinate with local utility providers and ensure the installation meets all health and safety standards.

  • How long does it take to build a garage conversion or backyard ADU?

    For garage conversions, most projects take around 8 to 12 weeks once permitting is complete. Detached ADUs may take 4 to 6 months, depending on size, site prep, and weather. We provide a clear timeline and milestone schedule during the planning phase and keep you updated throughout construction. Our contractors manage everything — from demolition to final finishes — so you stay stress-free.

  • Will adding an ADU increase my property value?

    Yes — in most cases, a well-designed ADU increases your home’s overall value and market appeal. In Bradenton’s competitive housing market, homes with legal secondary units often attract buyers looking for flexibility, multi-use living, or rental potential. Whether you plan to sell in the future or just want to create options for your family, building an ADU is often a smart investment that pays off in both value and versatility.
