What Is an ADU?
An accessory dwelling unit (ADU) is a secondary living space on the same lot as a primary residence. It includes its own kitchen, bathroom, and sleeping area. These units are sometimes referred to as in-law suites, granny flats, or casitas. They can serve a range of purposes — housing aging relatives, providing space for guests, creating a home office, or generating rental income.
Many cities and counties across Florida have updated their zoning regulations in recent years, allowing more single-family and multi-family properties to qualify for ADU construction. This has opened up opportunities for more homeowners to take advantage of the added flexibility an ADU provides.
To put the financial case in perspective, assisted living in Florida typically costs between $3,500 and $5,000 per month, while nursing home care can exceed $8,000 per month. Building an ADU for an aging family member can be a practical alternative. On the rental side, average monthly rents in Florida range from approximately $1,500 for a studio to $2,000 for a two-bedroom unit.
How Affordable ADU Works
Affordable ADU offers pre-designed base models that can be customized to match the homeowner's preferences and the style of the existing home. Using a pre-designed model can reduce design time and help move the permitting process along more quickly compared to starting from scratch.
Their process includes several key stages:
- Free on-site consultation — Their team visits the property to assess the space and discuss options tailored to the homeowner's goals and budget.
- Preconstruction design — A detailed design is developed in line with the client's requirements, with an emphasis on clear communication throughout.
- Construction estimate — A thorough estimate is provided upfront to give homeowners a clear picture of costs and scope, with the goal of avoiding unexpected change orders.
- Building and finishing — Construction is carried out by licensed and insured professionals. All ADUs are delivered fully finished and include appliances.
Throughout the build, Affordable ADU keeps clients informed at each stage of the process. Their work reflects a focus on quality craftsmanship and Florida-inspired design, with attention to detail in the finishing touches of every project.
Affordable ADU also provides resources to help homeowners explore financing options, making the path to building an ADU or completing a garage conversion more accessible. Their contractor license number is CGC1540231.
