An enclosure can help keep insects and debris out of the pool while preserving how you move between the house, the pool, and the yard. Start with what you want from the space, and the contractor takes it from there, whether that's a first cage or replacing one that's had enough.
Enclosing an existing pool
Many Riverview projects start with a pool and patio that are already in place. The contractor looks at where footings can go, the condition of the pool patio, how the cage will meet the house at the roofline and fascia, and where doors make sense for how you move between the house, the pool, and the yard. That evaluation shapes the design before anything is drawn.
Replacing an early cage
If your home came with a cage from Riverview's early growth, it may be reaching the point where rescreening isn't enough. If the frame is straight and sound, rescreening may be all you need. If it has bent members, corroded hardware, or a racked shape, or if repairs would cost close to what a new cage would, replacement is usually the better path, and it's a chance to rethink the roof style, doors, and screen.
Design choices
- Roof style: mansard, dome, gable, hip, or flat, depending on your roofline and how much height you want
- Screen: 18×14 standard, 20×20 no-see-um, pet screen, tuff screen, or solar shade, often mixed
- Frame finish: bronze and white are common choices
- Extras: doors, kick plates, and gutters where the cage meets the house
HOA approval, engineering, and the county permit
If your neighborhood has an HOA or deed restrictions, architectural approval usually comes first. Riverview is unincorporated, so the building permit goes through Hillsborough County. The county's checklist for residential screen enclosures calls for plans designed to the current Florida Building Code and signed and sealed by a Florida registered architect or engineer, a site plan showing setbacks and easements, and a recorded Notice of Commencement before the first inspection. The county lists a flat $380 residential permit for pool enclosures and screen rooms, including a $50 application fee, plus state surcharges. Your contractor prepares the plans and handles the permit filing; some paperwork, like HOA submissions, may still need your signature.
Near the Alafia River
The Alafia River runs through the northern part of Riverview. Properties in a special flood hazard area have added permit requirements under the county's checklist, and your contractor accounts for them in the plans if yours is one of them.
Pool safety and cost planning
Florida's building code allows a standard screen enclosure to serve as part or all of a pool's safety barrier, and Florida's pool safety law calls for pool access gates that open outward, close on their own, and latch automatically. Your contractor plans the doors with that in mind. For budgeting, our installation cost guide collects typical ranges, such as $8 to $15 per square foot for screen enclosures nationally (June 2026). The contractor's written proposal sets the actual price for your project.
Frequently asked questions
Do I need a permit to add a pool cage in Riverview?
Yes. New enclosures and replacements need a Hillsborough County building permit, which your contractor handles.
What does the county permit cost?
Hillsborough County lists a flat $380 residential permit for pool enclosures and screen rooms, including a $50 application fee, plus state surcharges.
Does our HOA need to approve the design first?
Usually, if your community has architectural rules. The contractor can tell you what drawings and details to submit, though you'll typically need to sign the submission yourself.
Can a cage be added to a pool patio that's already there?
Often, yes. The contractor evaluates the patio and where footings can go before recommending a design.
Our cage is reaching the end of its life. Replace it or rescreen it?
It comes down to the frame's condition and the cost comparison, not the age. If it's straight and sound, rescreening is usually enough. If not, or if repairs would run close to a new cage's cost, replacement makes more sense.
