If you’re considering expanding your home in Tampa Bay, one of the first questions you’re likely asking is: Do I need a permit? The short answer is yes — in most cases a permit is required for a home addition in Hillsborough County, FL. At ANM Contracting we help homeowners navigate the process so their project meets code, stays on schedule, and avoids costly delays.
What Counts as a “Home Addition”?
A home addition generally means any work that adds new usable space to your existing structure — for example, expanding a bedroom, adding a living room, or building a second-story. According to Hillsborough County’s Residential Single-Family Addition Requirements, these projects fall under the Building & Construction Services permitting rules.

If you are merely doing cosmetic updates (painting, flooring, shelving) or non-structural alterations, you may not need a full building permit. Hillsborough County
When a Permit Is Definitely Required
You will almost certainly need a permit if your project includes any of the following:
- Structural changes (adding walls, removing load-bearing elements)
- Expanding the footprint of the home (adding square footage)
- Moving or adding plumbing, electrical, HVAC systems
- Altering rooflines, floor levels, or foundations
- Enclosing a porch or converting open-air space into interior living
Hillsborough County’s guidelines for Single-Family Additions include checklist items such as site plan requirements, building plan review, structural design criteria, and more. Hillsborough County+1
