Additions & ADUs in the Palm Beaches
By BlueLadder Builders
More Room for More Life
A home that once felt spacious can start feeling tight as your needs change. You may need room for a parent to move closer, a private place for guests, or a home office that doesn’t share space with the dining table.
An addition or accessory dwelling unit (ADU) lets you explore those possibilities without leaving a neighborhood you love. BlueLadder Builders helps homeowners across Palm Beach, Martin, and Polk Counties add space that fits the way they live.
We coordinate with outside architects and engineers to address your project’s planning and structural needs. One of our owners stays directly involved throughout the work, with a detailed written scope and regular updates to keep you informed.
Both additions and ADUs are intensive projects with a lot of moving parts, but we're there to inform you at every step of the way.
Home Additions That Feel Like They Belong
An addition should do more than give you another room. It should connect comfortably to the spaces you already use, with a layout and exterior that feel cohesive.
BlueLadder Builders creates additions such as primary suites, expanded kitchens, and new living areas. We also help homeowners explore garage conversions or enclosing existing under-roof space when those options fit the property.
How you reach the new room matters as much as what goes inside it. We work with your design professionals to consider circulation, privacy, and natural light, along with the foundation and roof connections. That planning helps the extra space become a useful part of your home that looks like it's always been there.
Frequently Asked Questions About Home Additions
- How much does a home addition cost in Palm Beach, Martin, and Polk Counties?expand_more
-
Addition and expansion cost ranges are, on average, $150,000–$750,000. Size, foundation work, roof connections, and interior finishes all affect the cost.
Adding a bedroom involves a different scope than a primary suite with a bathroom or an expanded kitchen. These figures are a great starting point for planning. Your specific proposal will reflect the work required for your home.
- How long does it take to build a home addition?expand_more
-
Plan for approximately 5–9 months for a home addition, including 6–12 weeks for design and permitting and 14–24 weeks for construction. Permit review times are set by the county and vary by jurisdiction.
Second-story additions, complex structural connections, or extensive changes to the existing home may take longer. Material availability and required approvals also affect timing. BlueLadder Builders develops a schedule around your project’s scope and keeps you updated throughout the work.
- Is it better to build an addition or remodel an existing space?expand_more
-
Remodeling existing space may make sense if you have underused rooms or a garage conversion that could accommodate your needs. An addition is worth considering when rearranging the current layout still won’t provide enough room.
Compare how each option would affect storage, parking, and the way you move through the house. We help you explore the possibilities before committing to a construction plan.
- Can you add a second story to an existing house?expand_more
-
A second-story addition may be possible, but the existing foundation and structure need to be evaluated by a licensed structural engineer. Local height limits and other property restrictions also influence what can be built.
Reinforcing the house can add substantial work, so expanding outward may be worth comparing. BlueLadder Builders coordinates the professional input needed to understand your options. In a flood zone, a second story can also trigger the FEMA 50% substantial improvement rule, so we check that during planning
ADUs Give Everyone Their Own Space
Keeping family close doesn’t have to mean sharing every room. An ADU is a separate living space on your property, typically with its own kitchen, bathroom, and sleeping area.
BlueLadder Builders builds guest houses and ADUs and converts suitable garages, barns, and accessory buildings into living spaces. An ADU can offer a parent more independence or give extended-stay guests a comfortable place of their own.
Planning starts with the property. Available space, access, utility connections, and local requirements help determine what’s possible.
Frequently Asked Questions About ADUs
- How much does it cost to build an ADU in Palm Beach, Martin, and Polk Counties?expand_more
-
The cost range for guest houses and ADUs is $150,000–$500,000. Your cost depends on the size, finish selections, utility connections, and the condition of any existing structure being converted.
A new detached guest house requires different work than converting a suitable garage or another structure. Your written proposal will explain the scope and allowances specific to your project.
- How long does it take to build an ADU?expand_more
-
Allow approximately 7–13 months for a new detached ADU, including about 2 months for design, 2–6 months for permitting and approvals, and 3–5 months for construction.
Some stages may overlap, while complex site work or custom designs can extend the schedule. Conversions have different requirements depending on the existing building. BlueLadder Builders reviews those conditions and develops a project-specific schedule for you.
- What is the difference between an ADU and a home addition?expand_more
-
A home addition expands the main house, often creating a bedroom, larger kitchen, or living area connected to the existing rooms.
An ADU provides a separate living arrangement with its own essential facilities, such as a kitchen and bathroom. ADUs can be attached, detached, or created through a conversion, depending on local rules.
The right choice depends on how much independence and connection you want.
- Can you convert a garage or barn into an ADU?expand_more
-
A garage or barn may be suitable for an ADU conversion, but it needs evaluation before design begins.
The structure, ceiling height, moisture protection, and utility access all influence the work required. Local requirements also determine if residential use is allowed. BlueLadder Builders helps identify those needs and coordinates the professionals required to plan the conversion.
Our Remodeling Process
We start with a conversation about what you’d like to change, your budget, and your timing. Next, one of our partners visits your property to walk the space with you. You’ll receive a detailed written proposal that explains the scope, pricing, and allowances so you can make an informed decision.
Once we agree on the work, we coordinate the outside design and engineering support your project needs, work through selections, and manage permitting. We also establish the construction schedule and discuss how the work will affect your daily routine. Your JobTread portal keeps project details in one accessible place.
One of BlueLadder’s owners stays directly involved throughout construction, with regular updates and progress photos to help you follow the work. We finish with a quality check, a walkthrough together, and a final punch list. After completion, your project is backed by our one-year workmanship warranty and applicable manufacturer warranties.

Hear From Your Neighbors
John, Nick and Chris did a fabulous job on a few home renovations for our family. I then used them on a larger construction project for my office - loved how it all turned out! They’re working on a large project for my parents home now and they couldn’t be more thrilled with how it’s going. Thanks so much to John, Nick, Chris and their team!
