Florida Mobile Home Tie-Down Requirements, Plainly

Most people living in a mobile home around Ocala have never read the state rule their anchors are supposed to meet. It is more specific than you might expect. Below is what it says, in ordinary language, so you can crawl under your own home, look around, and know what you are looking at before you talk to anyone about price.

The official text on flrules.org is what counts, and we are not attorneys. Treat this as a working summary, accurate as of September 2026.

You do not need to know the rule numbers to spot most problems. Grab a flashlight and a tape measure:

1. Tug on every strap. A tie-down only does its job when it is tight. If one moves freely in your hand, it is slack, usually because the home has settled since it was set. Slack straps and an out-of-level floor tend to show up together, which is why we treat releveling and anchoring as one job.
2. Measure from strap to strap. Anything clearly wider than 5’4” fails the spacing rule.
3. Check both ends. The first and last anchors belong within two feet of each end of the home.
4. Find the plates. Each ground anchor should have a flat stabilizer plate at its head. Bare anchor shafts going straight into sand are a problem.
5. Inspect where steel meets soil. Light surface rust is expected. Metal that has visibly thinned or flaked away is not.
6. Tally them up against the anchor locations listed further down this page.

Find one of these and it is worth a second opinion. Find several on an older home and you are in very normal company here, which is exactly why our level check and tie-down inspection costs nothing.

Why the ground under Ocala matters

A ground anchor holds because the soil around it resists being pulled. Much of Marion County sits on deep, excessively drained sand (the Candler series is named for this county), with Ocala Limestone below that dissolves into karst depressions and sinkholes. Loose sand gives an anchor head room to lean, which is what stabilizer plates are there to stop, and settling over soft or shifting ground is what loosens straps over the years. None of that changes what the rule requires; it is the reason the requirements matter so much here.

The agency and the two rules

The Florida Department of Highway Safety and Motor Vehicles handles mobile home installation through its Bureau of Mobile Home and Recreational Vehicle Construction. The standards live in Chapter 15C-1 of the Florida Administrative Code, and two sections do the work:

• 15C-1.0104: installation standards for anchors and tie-downs.
• 15C-1.0102: installation standards for mobile and manufactured homes and park trailers.

Because the state takes installation this seriously, the people who do it in Florida must hold a state licence. Checking one is a short phone call, explained on our installer licensing page.

Wind zone for Marion County

Florida uses two zones. Wind Zone II covers the bulk of the state. Wind Zone III applies to a named list of south Florida and Gulf coast counties, two of them in the Panhandle, and asks for more anchors, stronger strapping and closer spacing.

Marion County is Wind Zone II. The bigger issue locally is age. Homes built before the federal wind standards took effect in July 1994 were anchored under lighter requirements than today’s, and the older parks around Ocala and Silver Springs are full of them.

The requirements, one at a time

Strap spacing. Diagonal tie-downs go no more than five feet four inches on centre, with an anchor within two feet of each end. This applies to new and used homes in all wind zones. It is a measurement, so a gap well past 5’4” is a fact, not a judgement call.

Plates on every ground anchor. Each one needs an approved stabilizing device of at least 180 square inches, hot-dipped zinc galvanized. Without it, the anchor head can tip when the strap loads up, and the anchor never reaches its rated holding power. On older installations this is one of the defects we see most.

Proper frame ties. Every frame tie, on a new or used home, uses a factory fabricated strap fastened at the top of the I-beam with a department-approved I-beam clamp. A strap looped around the beam and hooked back onto itself does not meet the rule.

Only approved hardware. Anchors, piers and tie-down components must all be tested, listed and approved by the Bureau. Plenty of bargain-priced work fails right here.

Anchor locations. Rule 15C-1.0102, read together with the manufacturer’s set-up manual, places anchors:

• At each end of every shear wall
• At each end of every I-beam
• As a frame tie at every vertical tie point
• At each end of every marriage wall (the centre seam on a multi-section home)
• At every ridge beam support post

Homes set before 1994

A pre-1994 home is not illegal just because of its age. It is, however, often light on anchoring compared with what is expected now, and it is the kind of home a park manager or insurance company will ask about first. If yours dates from then and has never been re-anchored, plan on finding something, and have it looked at on a calm day rather than after a storm warning.
