A large oak near the dig can move the pool, add a tree permit, or both — before excavation ever starts. If you are planning fiberglass pools in Hillsborough County, Pasco County, Pinellas County, or Hernando County, the City of Tampa, Hillsborough, Pasco, and Pinellas cities each treat trees differently. Knowing which office reviews your lot, and how big the trunk is in diameter (not circumference), keeps the permit and the dig from stalling for an inground pool builder working your Tampa, Brandon, Spring Hill, or Clearwater lot.

City of Tampa: 20 feet, Grand Trees, and the survey
Inside City of Tampa limits, the residential pool plan-review checklist is specific. You must identify all trees within 20 feet of the proposed work — species and diameter of each — on the site plan. City of Tampa Residential Pool & Spa Plan Review also sets protective distances:
- Specimen trees — 24 inches DBH — need a minimum 15-foot protective distance from construction.
- Grand Trees — 32 inches DBH or larger — need a minimum 20-foot protective distance from construction.
DBH means diameter at breast height (about 4.5 feet above grade), not circumference. A signed and sealed topographic survey is also required when the pool includes 1,000 square feet or more of decking, and that survey must show trees within 20 feet of the construction area (City of Tampa Residential In-Ground Pool Permit Application Guide). Encroachments into those protective distances may need an approved arborist certification under Tampa’s self-certified arborist program.
Removing a Grand Tree is hard by design. Tampa’s tree resources page notes that Grand Trees (32″ DBH or greater) generally need special circumstances for removal and may require public notice and board or council review if the tree is not hazardous. For a pool build, tree removal is usually evaluated on the building permit site plan rather than as a separate tree-only permit.
Unincorporated Hillsborough is not the same rule
A “Tampa” mailing address is not always inside city limits. In unincorporated Hillsborough County, the tree rules differ:
- Trees 12 inches or greater in trunk diameter (measured 4.5 feet above grade) generally need a tree-removal permit when they come out for a pool (Hillsborough County Residential Pool Requirements).
- A Grand Oak is an oak (genus Quercus) with at least 34 inches DBH, good-or-better condition, and a minimum tree-point score — a different definition than Tampa’s 32-inch Grand Tree (Hillsborough Grand Oak Regulations).
Hillsborough’s site plan must account for trees near the work. Do not assume the City of Tampa 20-foot / 32-inch Grand Tree rule applies on an unincorporated Valrico or similar lot — confirm the parcel’s jurisdiction first.
Pasco and Pinellas: show the trees, follow local permits
Pasco County residential pool applications ask the site plan to show location, species, and sizes of all trees within 20 feet of the construction area (Pasco County Residential Pool and Spa checklist). Tree removal for protected trees is a separate track under Pasco’s Land Development Code Chapter 800 / Section 802 tree preservation rules — including surveys of larger trees when a development approval is involved. Resolve tree questions before you expect the pool permit clock to run cleanly.
Pinellas County and its cities do not publish one county-wide “no trees within 20 feet if 32 inches DBH” rule that matches Tampa’s Grand Tree standard. What you will see instead:
- A current boundary or topographic survey is commonly required with residential pool permits in unincorporated Pinellas.
- Development checklists may call for a tree survey of trees 4 inches DBH and larger.
- Individual cities (for example Safety Harbor) often require surveys that show protected trees near the proposed pool and deck.
For Clearwater, Safety Harbor, Tarpon Springs, Seminole, Pinellas Park, St. Petersburg, and other Pinellas parcels, check the city or county office that actually issues the permit. Our service areas pages for Clearwater, Safety Harbor, and nearby cities note which office usually applies.
Roots, stumps, and what happens on dig day
Even when a trunk can stay, roots and stumps in the excavation footprint still have to come out so the fiberglass shell sits on a prepared bed. Large lateral roots under the planned deck or equipment pad can also force a layout change. Flag every tree within about 20 feet of the proposed pool and deck when you send your survey — that is the same window Tampa and Pasco ask you to show on paper.
At Pettit Fiberglass Pools we plan the shell location around protected trees whenever we can. If removal is allowed and needed, it is handled with the correct city or county tree process before dig day. Buried surprises such as old stumps, septic tanks, or rock are covered separately in our policy on when a pool price can change after you sign.
What to send us before the quote
- A current survey (or the best site plan you have) with the house, setbacks, and easements.
- Mark any tree whose trunk is roughly 12 inches or wider near the backyard — and any obvious Grand-sized oak.
- Note whether the parcel is inside city limits (especially City of Tampa vs. unincorporated Hillsborough or Pinellas).
- HOA tree or landscape rules, if any — those are a separate track from the building permit.

Trees-near-pool FAQs
Do Hillsborough and Pinellas ban trees within 20 feet of a new pool?
Not as one county-wide rule. Inside the City of Tampa, Grand Trees 32 inches DBH or larger need a minimum 20-foot protective distance from construction, and the site plan must identify all trees within 20 feet of the work. Unincorporated Hillsborough, Pasco, and Pinellas each have their own tree-survey and permit rules.
Is 32 inches a diameter or a circumference?
In the City of Tampa rules, 32 inches is diameter at breast height (DBH), measured about 4.5 feet above grade — not circumference.
Will Pettit remove stumps and roots in the dig area?
Yes. Roots and stumps in the excavation footprint are part of preparing the hole. Large protected trees that must stay may shift the pool location instead of coming out.
Do I need a tree survey for a pool permit?
Often yes. The City of Tampa and Pasco County both ask the site plan to show trees within 20 feet of construction. Confirm your city or county checklist for your parcel.
Can a big oak stop the pool project?
It can delay or relocate the pool. Grand and specimen trees have protective distances; removal may need a separate tree review, mitigation, or public process. Flag large trees early so the layout accounts for them.
