Neighbor's water running into your yard?
What Florida's reasonable-use rule means in plain terms, how to document the runoff, and how to protect your yard on your own side — without sending the water back.
Free yard inspection within 48 hours · written price before we dig
"Neighbor's yard drains into mine" is one of the most stressful drainage problems because it is not only about water. In Florida the general rule is that you may not redirect your water onto a neighbor's property — and neither may they. But water also runs downhill naturally, and a lower lot will always receive some water from a higher one. Where that line falls in a dispute is a legal question we cannot answer for you; what we can do is fix the water on your side and make sure our fix never sends it back.
This page is not legal advice. If you are in a dispute, talk to your HOA or an attorney. Here is the practical side.
Why it happens
A neighbor's downspout aimed at the line
A downspout or a pipe that empties at or near the property line concentrates a roof's worth of water onto your lot.
A lot that sits higher
Newer construction or fill next door can raise the neighbor's grade above yours, so their surface water runs to you.
The shared side-yard swale has settled
The swale between two houses was meant to carry both lots' water to the street; once it is flat, the water stops in the middle.
Hardpan moving water underground
Rain soaks in, stops on the hardpan 12 to 36 inches down and moves sideways — across the property line, below the surface.
What you can check this week
- Photograph or video the water coming across during a storm, with the date.
- Note where it enters your lot and where it ends up.
- Look at the neighbor's downspouts and any pipes ending near the line — from your own side.
- Talk to the neighbor; many cases are a downspout neither of you had noticed.
The fixes, from the cheapest up
Which one you need depends on where the water comes from and where it can legally go — that is what the free inspection is for.
Intercept with a French drain
A drain along your side of the property line catches surface and underground water before it reaches your house and carries it to the street or a dry well.
$20 – $45 / ftFrench Drain Installation
Restore the side-yard swale
Re-shape the swale on your side so water from both lots moves to the street instead of stopping in the middle.
$1,000 – $5,000Yard Regrading & Swales
Catch basin where it collects
A basin at the spot where the runoff ponds on your lot, piped to a legal outlet.
$500 – $1,500 per pointCatch Basins & Channel Drains
Dry well where there is no outlet
On lots with no curb or swale, a dry well sized for the storm — tested first, because near the river and the coast the water table can be too high.
$1,000 – $3,000Dry Well Installation

Neighbor's runoff: FAQ
Can my neighbor drain water into my yard in Florida?
Florida generally does not allow anyone to redirect water onto a neighbor's property, but natural runoff from a higher lot to a lower one is a different matter. How that applies to your situation is a legal question — talk to your HOA or an attorney. We can fix the water on your side either way.
What can I do about my neighbor's water runoff?
Document it during storms, talk to the neighbor, and involve the HOA if you have one. On your own lot, a French drain along the line, a restored swale or a catch basin can intercept the water and carry it to the street.
Will your fix send the water back to my neighbor?
No. We discharge to the street, a swale on your lot or a dry well, never at the property line, and the outlet is marked on the plan you sign.
Do I need a permit to fix runoff from a neighbor?
A private drain that stays on your lot and does not change runoff onto a neighbor usually does not. Tying into city storm sewer, a public easement, a pond or wetland does, and then the permit is part of the written scope.
