The Best ADU Builders in St. Petersburg, FL
Published by Tampa Bay ADU, an ADU design-build brand serving homeowners in St. Petersburg and throughout the Tampa Bay area. We're included in this comparison so you can evaluate our services alongside other local ADU builders.
Finding the right ADU builder in St. Petersburg takes more than comparing prices. Your project may involve zoning requirements, site constraints, permitting, architectural plans, utilities, and construction. The companies below were selected based on their documented ADU services, local presence, public reviews, and contractor licensing information.
How We Selected These ADU Builders
We researched each company using its Google Business Profile, official website, and Florida DBPR records where available. We focused specifically on builders with documented ADU services and a connection to the St. Petersburg market.
Google Reviews
We included each company's publicly visible Google rating and review count. Reviews provide useful context about customer experience, but they should not be treated as a guarantee of future results.
ADU Services
We looked for evidence of actual ADU work, including detached and attached units, garage conversions, in-law suites, ADU design, and permitting.
Licensing
Florida contractor license information was checked against DBPR where possible. When information could not be independently verified, we identify that rather than presenting an unverified number as fact.
Local Service Area
We prioritized companies that specifically serve St. Petersburg or nearby Tampa Bay communities rather than businesses making only broad statewide service claims.
What to Consider When Choosing an ADU Builder
Does the Builder Handle Permitting?
Ask whether the builder manages the permitting process or expects the homeowner to coordinate applications, plans, revisions, and inspections.
What Type of ADU Do They Build?
Not every builder handles every type of accessory dwelling unit. Confirm whether they build detached ADUs, attached units, garage conversions, or in-law suites before requesting a proposal.
How Much ADU Experience Do They Have?
A contractor who builds custom homes or remodels may not have the same experience navigating an ADU project. Ask for examples of completed projects similar to yours.
What Is Included in the Proposal?
Compare more than the construction price. Ask whether design, engineering, permitting, utility connections, site work, and other project costs are included.
