We understand that building an Accessory Dwelling Unit (ADU) is a huge decision. Our goal is to empower you with honest and reliable ADU cost information to help you budget for your project.
Choose from three thoughtfully designed ADU layouts, each available in one- or two-story builds to fit your property, your budget, and how you plan to use the space. Please Note: This pricing reflects only costs associated to construction, not including preconstruction fees. Ask us for more details.
Perfect for guests, rental income, or a private workspace. A smart, compact solution with everything you need in a smaller footprint.
Great for longer-term stays or a more spacious rental. Offers more comfort and flexibility while still keeping it efficient.
Ideal for families, multigenerational living, or maximizing rental returns. A true secondary home experience on your property.
It’s essential to consider the various ownership costs associated with ADUs to make an informed decision. ADUs generally need less maintenance compared to regular houses. That means lower expenses for you as a homeowner. With fewer square footage and simpler systems, you’ll spend less on maintenance, repairs, and utilities.
Design, permitting, site work, materials, and labor make up the largest share of your ADU investment.
A new ADU adds value to your property, so expect your tax assessment and homeowner’s premium to increase to reflect it.
An extra living space means more water, electricity, and gas, whether it’s billed through your main meters or separate ones.
If you plan to rent your ADU, budget for tenant screening, maintenance, and upkeep, or for a manager to handle them for you.
St. Pete ADUs offer more than flexible living space. They’re a smart financial investment. With visitors coming to the area year-round, a rental ADU can be a steady source of income, and in our experience, an ADU in the St. Petersburg area can generate approximately $35,000 in gross annual income.
An ADU also adds long-term value to your property. Across America’s biggest cities, homes with an ADU are priced 35% higher on average than homes without one, so as St. Pete’s real estate market continues to grow, your investment grows with it.
One thing to double-check before this goes live: the original leans on tourist rentals, and I kept the rental framing general because St. Pete has rules on short-term rental of ADUs. It’s worth confirming with Jeff that the $35K figure reflects rentals that fit the city’s current requirements.
