Florida's New Series LLC Law: A Game-Changer for Developers

On July 1, 2026, Florida joined the ranks of Delaware, Texas, Nevada, and a select group of other states by implementing its new Protected Series LLC law. Signed by Governor Ron DeSantis on June 20, 2025, as Senate Bill 316, and codified in Sections 605.2101 through 605.2802 of the Florida Revised Limited Liability Company Act, this legislation introduces a powerful new tool for asset protection and business structuring — one that is particularly well-suited for residential developers building single-family homes.

For developers who have long relied on forming dozens of individual LLCs to isolate liability across projects and individual properties, the series LLC offers a streamlined, cost-effective alternative that could fundamentally change how you structure your developments. Here is what you need to know.

What Is a Series LLC?

A series LLC is a single "parent" LLC that can establish one or more internal divisions — called "protected series" — beneath it. Each protected series can separately own assets, incur liabilities, enter into contracts, and conduct business activities, all while remaining under the umbrella of a single parent entity.

Think of it as a single company with internal walls. The parent LLC is the overarching structure, and each protected series operates as if it were its own LLC — with its own assets, its own liabilities, and its own members and managers — but without the need to file a completely separate entity with the state for each one.

Under Florida's law, an existing Florida LLC becomes a series LLC when it files its first "certificate of designation of a protected series" with the Florida Department of State. From that point forward, the LLC can continue to add protected series as needed. Each protected series must include the parent LLC's name along with the words "protected series" or the abbreviation "PS" in its name, ensuring transparency for anyone doing business with the entity.

How the Liability Protection Works

The real power of the series LLC lies in its dual liability shields.

The vertical shield is the traditional LLC liability protection that Florida business owners are already familiar with — it protects the owners (members) personally from the debts and obligations of the entity. This shield exists in every Florida LLC, and it carries forward into the series LLC structure.

The horizontal shield is the new protection introduced by the series LLC law. This shield operates between and among the protected series themselves, and between each protected series and the parent LLC. In practical terms, this means:

·      The debts and obligations of Protected Series A cannot be enforced against the assets of Protected Series B, Protected Series C, or the parent LLC.

·      A creditor of one protected series is limited to the assets associated with that specific series — and only that series.

·      A creditor of the parent LLC cannot reach into the assets held by any individual protected series.

This horizontal shield is built on two statutory principles: a non-liability rule, which protects the parent LLC and each protected series from liability for the debts of one another, and a non-recourse rule, which limits creditor recourse to only the associated assets of the specific series that incurred the debt.

There is a critical caveat, however: the horizontal shield only holds up if the series LLC and each of its protected series follow strict recordkeeping requirements. Florida law requires that the assets and liabilities of each series be clearly documented in records sufficient to allow a reasonable person to identify each asset, determine which series it belongs to, and distinguish it from the assets of every other series and the parent LLC. If those formalities are not followed and the lines between series become blurred, a court may allow a creditor to "pierce" the horizontal shield — just as courts can pierce the corporate veil in traditional entity structures.

Why This Matters for Residential Developers

For developers building single-family homes — whether in a single large-scale development or across multiple projects — the series LLC structure offers an elegant solution to a long-standing challenge: how to protect each property without the expense and administrative burden of forming a separate LLC for every single home.

The Traditional Approach: A Separate LLC for Every Property

Historically, developers seeking to isolate liability at the individual property level have formed a separate LLC for each home or each phase of a development. A developer building 50 single-family homes might form 50 separate LLCs, each holding title to one property. While this approach achieves strong liability isolation, it comes with significant downsides:

·      Formation costs multiply quickly. Each LLC requires its own articles of organization, filing fees, and registered agent.

·      Annual compliance adds up. Each LLC must file its own annual report, maintain its own records, and pay its own state fees every year.

·      Administrative overhead is substantial. Managing dozens or hundreds of LLCs means separate operating agreements, separate bank accounts, separate tax returns, and separate accounting for every entity.

·      Transactional friction increases. Selling individual lots or homes, obtaining financing, and dealing with title insurance becomes more cumbersome when each property sits in its own entity.

For a developer with projects in multiple communities or across different markets, this traditional approach can become extraordinarily expensive and difficult to manage.

The Series LLC Alternative: One Entity, Many Shields

Under the new Florida law, a developer can form a single series LLC and create a separate protected series for each individual home within a development — or for each lot, each phase, or each entire project, depending on the level of granularity desired.

Example: A 30-Home Subdivision

Consider a developer building a 30-home subdivision. Instead of forming 30 separate LLCs, the developer forms one series LLC — say, "Sunshine Homes Development, LLC" — and then designates 30 protected series, one for each lot:

·      Sunshine Homes Development, LLC – PS Lot 1

·      Sunshine Homes Development, LLC – PS Lot 2

·      Sunshine Homes Development, LLC – PS Lot 3

·      ...and so on through Lot 30.

Each protected series holds title to its respective lot and home. If a construction defect claim arises on Lot 12, only the assets associated with that specific series — PS Lot 12 — are exposed to the claim. The other 29 homes, and any assets held by the parent LLC itself, remain protected behind the horizontal liability shield.

Example: Multiple Developments Across Florida

The structure scales equally well for developers operating across multiple communities. A developer with projects in Jacksonville, Orlando, and Tampa might structure the parent LLC's protected series by project:

·      Florida Builder Group, LLC – PS West Palm Beach Phase I

·      Florida Builder Group, LLC – PS Orlando Lakeside

·      Florida Builder Group, LLC – PS Tampa Meadows

Or, for maximum protection, the developer could create a protected series for each individual home across all developments. The flexibility is essentially unlimited.

Key Benefits for Developers

1. Significant Cost Savings

Rather than paying formation fees, registered agent fees, and annual report fees for dozens or hundreds of separate LLCs, the developer maintains a single parent LLC. Creating a new protected series requires only a certificate of designation filing with the Florida Department of State — a far simpler and less expensive process than forming an entirely new entity.

2. Reduced Administrative Burden

One parent entity means one registered agent, one primary operating agreement (with provisions governing each series), and a consolidated organizational framework. While each protected series must maintain its own separate records and accounts to preserve the liability shield, the overall administrative load is substantially lighter than managing an equivalent number of standalone LLCs.

3. Scalability

As a development grows or as the developer takes on new projects, adding a new protected series is straightforward. There is no need to draft entirely new organizational documents, retain new registered agents, or navigate the full entity formation process for each additional property. This scalability is particularly valuable for builders engaged in ongoing, phased development.

4. Flexibility in Ownership and Management

Each protected series can have its own associated members and managers, separate from the parent LLC and from other protected series. This is particularly useful for developers who bring in different investors or joint venture partners for different projects or phases. One protected series might have one set of investors, while another series within the same parent LLC has entirely different ownership — all under one organizational umbrella.

5. Streamlined Exit Strategy

When it comes time to sell individual homes or lots, the developer can transfer the assets of a specific protected series — or potentially the entire series itself — without disturbing the rest of the development or the parent entity's structure. This provides cleaner exit options compared to unwinding one of many standalone LLCs.

Critical Compliance Requirements

The benefits of the series LLC structure are powerful, but they are not automatic. Developers must be diligent about maintaining the formalities that the statute requires, or risk losing the horizontal liability shield entirely.

Separate Recordkeeping Is Non-Negotiable

Florida law requires that each protected series create and maintain records that:

·      State the name of the protected series and describe each associated asset with sufficient specificity for a disinterested, reasonable individual to identify the asset and distinguish it from assets of the parent LLC or any other protected series.

·      Determine when and from whom the protected series acquired each asset.

·      If the asset was acquired from the parent LLC or another protected series, document the consideration paid, the payor, and the payee.

In practice, this means developers should maintain separate books, separate bank accounts, and clear title and ownership records for each protected series. Co-mingling funds or assets between series — even inadvertently — could jeopardize the liability protection the structure is designed to provide.

Special Rules for Real Property

Importantly, the Florida legislature included non-uniform provisions specifically addressing real property. Sections 605.2301(2)(b) and 605.2301(3)(b) of the statute address the interplay between protected series and recorded title to real property, liens, mortgages, and other recorded instruments. A deed or other instrument granting an interest in real property to a protected series that is properly recorded is conclusive as to the authority of the person signing and delivering the instrument, and also serves as a record for purposes of associating the asset with that protected series.

This is a critical provision for developers and their counsel. It means that properly recorded deeds vesting title in a specific protected series will serve the dual purpose of conveying title and satisfying the statutory association requirements — provided the records are properly maintained.

Insurance and Banking Considerations

Developers should work with their insurance brokers and lenders to ensure that policies and loan documents properly account for the series LLC structure. Because the law is new to Florida, some lenders, title companies, and insurance carriers may not yet be fully familiar with how to underwrite or insure assets held in a protected series. Early engagement and education on the structure will help avoid transactional delays.

Important Limitations and Considerations

The Law Is Untested in Florida Courts

Because the Protected Series LLC law only took effect on July 1, 2026, there is no Florida case law interpreting these provisions. While the statute is based on the Uniform Protected Series Act — which was developed over years by the Uniform Law Commission — how Florida courts will apply the horizontal liability shield, and under what circumstances they might allow it to be pierced, remains to be seen. Developers should structure their series LLCs conservatively and with strict compliance in mind.

A Protected Series Cannot Exist Independently

Each protected series is permanently tied to its parent LLC. If the parent series LLC is dissolved, all of its protected series are automatically dissolved as well. Developers should consider this dependency when planning long-term hold strategies and ensure that the parent entity remains in good standing at all times.

Restrictions on Certain Transactions

The statute imposes significant limitations on mergers, conversions, domestications, and other entity transactions involving protected series. A protected series cannot be an acquiring, acquired, converting, or surviving entity in a merger or similar transaction on its own. This means that developers contemplating future corporate restructuring, sales, or consolidation should seek legal counsel to understand the transaction limitations before choosing the series LLC structure.

Tax Treatment

While the series LLC structure can simplify operations, the tax treatment of protected series should be carefully analyzed with qualified tax advisors. Federal and state tax treatment of series LLCs can vary, and developers need clear guidance on how each protected series will be treated for income tax, property tax, and transfer tax purposes.

Getting Started: Steps for Developers

If you are a residential developer interested in utilizing the new Florida series LLC structure, here are the key steps to consider:

1.     Consult with experienced legal counsel. The series LLC is a powerful tool, but it requires careful structuring from the outset. An attorney experienced in both entity formation and construction law can help you design a structure tailored to your specific development activities.

2.     Evaluate your current entity structure. If you are already operating through multiple standalone LLCs, assess whether consolidating into a series LLC makes sense for your portfolio. The answer depends on factors including the number of properties, existing lender and title company relationships, and long-term plans for each property.

3.     Establish robust recordkeeping systems. Before designating your first protected series, put in place the accounting systems, banking relationships, and document management processes necessary to maintain strict separation between each series.

4.     Coordinate with lenders, title companies, and insurers. Because the law is new, proactive communication with your financial and insurance partners will smooth the path for transactions involving assets held in protected series.

5.     Plan for ongoing compliance. The liability protection offered by the series LLC is earned through consistent, disciplined compliance with the statute's requirements — not simply granted by filing the right paperwork. Budget for ongoing legal and accounting oversight to protect your investment.

Conclusion

Florida's new Protected Series LLC law represents a significant opportunity for residential developers. By allowing a single parent LLC to house multiple protected series — each with its own assets, liabilities, and liability shield — the law offers a way to achieve the property-by-property isolation that developers need, without the cost and complexity of managing dozens or hundreds of separate entities.

For developers building single-family homes, whether in a single community or across the state, the series LLC structure deserves serious consideration as part of your overall business and risk management strategy. The key is getting the structure right from the start and maintaining the compliance discipline that the statute demands.
