Florida Mobile Home Tie-Down Requirements, Plainly

Florida regulates mobile home anchoring in real detail, and most homeowners never see the rule. This page sets out what it actually requires, in plain terms, so you can look at your own home and form a view before anybody quotes you anything.

We are installers rather than lawyers, and the official text at flrules.org controls. This is a practical summary current as of September 2026.

Who writes the rules

Anchoring and installation sit with the Florida Department of Highway Safety and Motor Vehicles, through its Bureau of Mobile Home and Recreational Vehicle Construction, in Chapter 15C-1 of the Florida Administrative Code.

Three rules matter here:

• 15C-1.0102, installation standards for mobile and manufactured homes and park trailers.
• 15C-1.0103, foundations and piers.
• 15C-1.0104, installation standards for anchors and tie-downs.

That is also why installation work in Florida is licensed. Verifying a licence takes one call and is covered on our installer licensing page.

Wind zones, and which one you are in

The federal construction standard at 24 CFR 3280.305 designs Wind Zone II homes against a 100 mph wind and Wind Zone III homes against 110 mph. It names Florida’s Zone III counties: Broward, Charlotte, Collier, Dade, Franklin, Gulf, Hendry, Lee, Martin, Manatee, Monroe, Palm Beach, Pinellas, and Sarasota. Every other Florida county is Zone II. Sumter, Lake, and Marion counties are all Wind Zone II.

Two things make anchoring worth checking here specifically. The parks along State Road 44 and the original communities in Lady Lake and Leesburg hold a great many homes set before the 1994 federal standards, which were anchored to a lighter rulebook than today’s. And this is not a quiet corner of the state for wind: the EF-3 tornado of February 2, 2007 touched down near Wildwood and ran 16.5 miles through The Villages and Lady Lake, Hurricane Irma put a 60-knot gust on Leesburg’s airport in September 2017, and Milton’s peak gusts in Sumter County ran 40 to 50 mph in October 2024. That is exactly the load an anchor system exists for and exactly what loosens straps that were already marginal.

What the rule requires, item by item

Diagonal tie-down spacing. For new and used homes, in all wind zones, “no farther apart than five feet four inches (5’4”) on center with anchors placed within two feet (2’) of each end.”

This is the check a homeowner can actually make. Take a tape measure under the home and measure between straps. If they are noticeably farther apart than 5’4”, or if the end anchors are well back from the ends, that is a finding, not a matter of opinion.

Longitudinal tie-downs. Every new and used home installed after the rule took effect “must have longitudinal tie-downs or other approved longitudinal stabilizing systems,” with “at least four (4) anchors and straps” at the end of each section, “i.e., 16 per double-wide home.” These resist the wind along the length of the home, and they are the item most often missing entirely on an older installation.

Anchor classes. The rule sets two. Type I, for homes manufactured before July 13, 1994, “shall be tested to a working load of three thousand one hundred and fifty (3,150) pounds, with an ultimate load of four thousand seven hundred twenty-five (4,725) pounds.” Type II, for homes built after that date, is tested to a 4,000-pound working load and 6,000 pounds ultimate.

Frame ties. All frame ties must use “a factory fabricated strap connected at the top of the I-beam to an I-beam clamp approved by the department.” Not a strap wrapped round the beam and hooked to itself.

Approved components. Frame tie components have to be approved by the department under the companion rules, and the anchors are tested to the loads above. This is the requirement that quietly disqualifies a lot of cheap work.

Piers, while you are under there

Rule 15C-1.0103 puts the maximum pier spacing at eight feet, with the first pier within two feet of either end of the home, and requires at least eighteen inches between the finished grade and the bottom of the I-beam. Single-stack block piers are limited in height; anything over 36 inches has to be double-tiered and interlocked. Rule 15C-1.0102 says that when the soil bearing capacity is not known, the installer assumes 1,000 pounds per square foot, which on the loose sands around Wildwood is the honest number more often than not. Over-tall single stacks and piers on undersized pads are what a pier survey finds.

What you can check yourself, in fifteen minutes

1. Measure the strap spacing. More than 5’4” apart is a finding.
2. Look at the end anchors. They should be within two feet of each end.
3. Grab each strap. If you can move it by hand it is not in tension, and a tie-down only works in tension. Every bit of settling leaves straps slack, which is why anchoring and releveling are one conversation.
4. Look for longitudinal ties at the ends of each section, running along the home rather than across it. None at all is common on older installs.
5. Look at the ground end of each anchor, where metal meets damp sand. Surface rust is normal; significant section loss is not.
6. Count them. Compare what is there against the spacing above, or run the tie-down planner.

Any of those is worth a professional look. All of them together on an older home is common, and it is why we do the level check and tie-down inspection free.

The pre-1994 question

Homes set before the 1994 federal installation standards were anchored to a lighter rulebook than the one in force today, and the Florida rule keeps the Type I anchor class for exactly those homes. They are not automatically illegal, but they are frequently under-anchored by current expectations, and they are the homes where an insurer or a park will ask questions first.

If your home is that vintage and has never been re-anchored, assume there is work to do and get it looked at rather than waiting for a storm or an inspection to raise it.
