Owners often ask whether a shed, pool, patio, or enclosure needs a permit, and, separately, whether it needs an engineer. These are two different questions, and the answers depend on the project and the jurisdiction.
This guide covers the general picture. We confirm what your specific project requires before any work starts.
Permit vs engineered plans
A permit is the jurisdiction's approval to build. Engineered plans are the sealed drawings or calculations that support the permit where the code requires them. A small project may need a permit but not engineering; a larger or wind-loaded one usually needs both.
Where engineering is commonly required
Sheds and accessory structures above a certain size generally need engineered anchorage; pools need documented bonding and a compliant barrier; screen enclosures need engineered members and connections. Patios and slabs vary by scope and attachment.
Questions
Do I need a permit for a small shed in Florida?
Many jurisdictions require a permit for sheds above a small size threshold, and engineered anchorage above another. The thresholds vary by jurisdiction and are stricter in the HVHZ. We confirm what applies to your shed.
Does a screen enclosure or pool need engineering?
Screen enclosures typically need engineered members and connections; pools need documented bonding and barrier compliance. We confirm the requirement for your specific project.
