Florida Just Let You Protect 10 Rental Properties With One LLC Instead of Ten. Here's How the New Series Law Works.

One Filing. Unlimited Properties. A Legal Wall Between Every One.

As of July 1, 2026, a landlord in Tampa can hold ten rental houses inside a single LLC — and still keep a slip-and-fall lawsuit at property #3 from touching the other nine. That's not a loophole. It's a brand-new statute.

For 25 years, every Florida real estate investor got the same advice from every asset-protection attorney: one property, one LLC. It works, but it's expensive and it doesn't scale — ten properties means ten formation filings, ten annual reports, ten registered agents, ten sets of paperwork. Most investors either eat the cost or get lazy and stack properties into one entity, which defeats the whole point of liability protection.

Florida just gave investors a third option. CS/SB 316, signed by Gov. Ron DeSantis on June 20, 2025 and effective this month, adds "Protected Series" provisions to Chapter 605 of the Florida Statutes — new sections 605.2101 through 605.2802. It lets one parent LLC spin up internal, liability-walled compartments for each property, without forming a new legal entity for every one. This piece breaks down exactly how it works, what it actually costs, and where the real risk still sits.

How the "Horizontal Shield" Actually Works

A traditional multi-LLC structure uses a vertical shield — each property sits in its own separate legal entity, and decades of case law back up that separation. Florida's new structure works differently. One parent LLC creates multiple internal "protected series," each with its own members, managers, assets, and liabilities, even though none of them is a separate legal entity from the parent.

The protection that matters is the horizontal shield: a creditor who wins a judgment against one series generally can't reach the assets held by a different series, or by the parent LLC itself, according to Holland & Knight's summary of the legislation. A tenant hurt at your Series A duplex can only go after Series A's bank account and equity — not your other nine properties.

Florida joins a short list of states with a real series LLC framework — Delaware has had one since the mid-1990s, with Illinois and Nevada following in 2005. That list matters because plenty of states where you might also own property — Pennsylvania, New York, Massachusetts, Colorado among them — don't recognize series LLCs at all, which creates real uncertainty if you're holding a Florida series LLC's interest against an out-of-state judgment.

The effective date itself is telling: the law was signed in June 2025 but doesn't take effect until July 2026 — a full year later — specifically because Florida's Department of State needed that runway to build the registration software and procedures for series entities. This is infrastructure the state just finished building, not a rule that's been quietly in effect for years.

The Numbers: What Protecting Ten Properties Actually Costs

Here's the filing-fee math for an investor with ten Florida rental properties, based on the state's fee comparison:

• Ten separate LLCs: 10 formation filings at $125 each ($1,250 up front), plus 10 annual reports at $138.75 each ($1,387.50 every year after), plus 10 registered agent arrangements.
• One Protected Series LLC: one parent formation filing plus series designations, and one annual report — a fraction of the recurring state-level cost.

That's a real, recurring savings on the paperwork Florida itself charges you. But don't mistake it for "protection on the cheap." The same source is blunt about the catch: to actually preserve the horizontal shield, each series still needs its own bank account, its own insurance policy, and its own bookkeeping — the exact overhead that made ten separate LLCs expensive in the first place. The state filing fees shrink. The professional and administrative load mostly doesn't.

Common Mistakes Investors Make Here

• Treating "one LLC" as "one bank account." Commingling funds across series is the single fastest way to blow up the shield you just paid to set up — the law requires records detailed enough that a "disinterested, reasonable person" could tell which assets belong to which series at any moment.
• Assuming this replaces landlord insurance. A liability shield determines what a creditor can collect after a judgment. It does nothing to stop the lawsuit, the legal fees, or the underlying claim. You still need a policy on every property, in every series.
• Ignoring the unresolved legal questions. How Florida's charging-order protections apply to series interests — especially for single-member series — hasn't been tested in court, and neither has the bankruptcy question of whether a trustee can sweep in every series' assets at once or must treat them separately. Holland & Knight flags both as open.
• Assuming lenders and title companies are ready for this. First Title Group's guidance to closing professionals says title agents must independently verify which series is actually buying or selling, that it was properly established, and that the signatory has real authority — extra friction at the closing table that a normal LLC transfer doesn't have. Don't assume your lender's underwriting team has seen one of these yet.

How to Use PropGPT for This

The hard part of a series LLC isn't the filing — it's deciding which properties actually need to be walled off from each other, and then keeping the records clean enough to survive a challenge. That's exactly the kind of portfolio-level organizing work PropGPT is built for.

"List my rental properties grouped by estimated liability risk — age of structure, pool or trampoline presence, tenant type, and any prior claims — so I can decide which properties need their own protected series." This turns a vague "should I split these up" question into a ranked list you can actually act on.

"Generate a per-property income and expense tracking template that keeps each property's financials cleanly separated, in a format that would satisfy Florida's series LLC recordkeeping standard." Gives you the bookkeeping scaffolding before you form anything — the exact gap that trips up investors after the fact.

"I own 8 Florida rental properties valued between $150,000 and $400,000 each. Compare the estimated annual cost of one Protected Series LLC versus 8 separate LLCs, including state filing fees, registered agent costs, and estimated bookkeeping and insurance overhead per entity." Forces the real math — including the overhead that doesn't shrink — instead of just the headline filing-fee savings.

"I'm buying a property from a seller organized as a Florida Protected Series LLC. Draft a due-diligence checklist to confirm the series was properly formed, its records are separated from the parent LLC, and the person signing has authority to sell." Puts you ahead of the verification problem First Title Group is warning closing agents about.

"Draft the questions I should ask my lender and title company about financing and insuring a property held inside a Florida Protected Series LLC, given that this structure has no established underwriting track record yet." Surfaces friction before it costs you a closing date.

The Bottom Line

Florida's Protected Series LLC isn't a universal upgrade over the one-property-one-LLC playbook — it's a new tool that works best for investors holding a stack of lower- to mid-value properties, where separate-LLC fees and paperwork have gotten disproportionate to what's actually being protected. If you're holding two high-value assets, the decades of case law behind traditional separate LLCs are still probably worth more to you than an untested statute.

But if you're the investor with eight or ten mid-size rentals paying for eight or ten sets of filings every year, this is worth modeling now — the law is live, the Department of State has had a year to get its systems ready, and the first movers will be the ones who show up to Florida's Division of Corporations with clean structures already planned. Run the numbers on your actual portfolio before you assume the answer.
