Ohio Series LLC Formation Guide for Real Estate Investors

Holding five duplexes in Cleveland, three student rentals in Columbus, and a mixed-use retail building in Cincinnati inside a single traditional LLC is one of the most dangerous mistakes an Ohio real estate investor can make. If a tenant suffers a catastrophic injury or a contractor files a major lawsuit against that single LLC in the Cuyahoga County Court of Common Pleas, Cleveland or the Franklin County Court of Common Pleas, Columbus, the judgment creditor can seize the equity and rental cash flow of every single property inside the company. Historically, the only way to prevent this domino effect was to pay separate state formation fees and manage separate corporate filings for dozens of individual subsidiary LLCs.

With the enactment of the Ohio Revised Limited Liability Company Act, codified at Ohio Rev. Code § 1706.76 through Ohio Rev. Code § 1706.7613, real estate investors gained a powerful alternative: the Ohio Series LLC. This structure allows a single master (parent) LLC to establish an unlimited number of independent internal series (cells), each holding its own real estate, bank accounts, and liabilities. Below is the complete legal guide to forming and maintaining an Ohio Series LLC for real estate asset protection.

Separating Liability Between Properties

The core advantage of an Ohio Series LLC is its statutory internal liability shield (horizontal and vertical protection). Under Ohio Rev. Code § 1706.761(A), the debts, liabilities, obligations, and expenses incurred or contracted for with respect to a specific series are enforceable only against the assets of that specific series, and not against the master LLC generally or any other series within the portfolio. Furthermore, under Ohio Rev. Code § 1706.76(C), each individual series has the independent legal power in its own name to contract, hold and convey title to real estate, grant mortgages and liens, and sue or be sued.

However, this internal firewall is not automatic. Pursuant to Ohio Rev. Code § 1706.761(B), Ohio courts will enforce the liability shield between properties only if all three statutory conditions are strictly satisfied:

1. Mandatory Notice in the Articles of Organization: The master LLC's Articles of Organization filed with the Ohio Secretary of State, Columbus must contain an explicit statement that the company may have one or more series of assets subject to statutory liability limitations under Ohio Rev. Code § 1706.761(B)(3).
2. Explicit Operating Agreement Authorization: The master LLC's operating agreement must establish (or provide for the establishment of) the separate series and explicitly state the liability limitations of Ohio Rev. Code § 1706.761(A).
3. Strict Separate Recordkeeping and Accounting: The records maintained for each individual series must account for the assets associated with that series separately from the assets of the master LLC and any other series, in accordance with Ohio Rev. Code § 1706.762(B).

If an investor commingles rental deposits or fails to keep separate accounting ledgers, a plaintiff's attorney in the Hamilton County Court of Common Pleas, Cincinnati can argue that the statutory prerequisites of Ohio Rev. Code § 1706.761(B) were never met-or seek to pierce the veil under Belvedere Condominium Unit Owners' Assn. v. R.E. Roark Cos., Inc., 67 Ohio St. 3d 274 (OH Supreme Court 1993) and Dombroski v. WellPoint, Inc., 119 Ohio St. 3d 506 (OH Supreme Court 2008)-exposing the entire real estate portfolio to a single judgment.

Strategic Use Cases for Ohio Real Estate Investors

Because each series can have different members, managers, and investment objectives under Ohio Rev. Code § 1706.76(A), real estate sponsors across Columbus, Cleveland, Cincinnati, Akron, and Toledo deploy Series LLCs in several ways:

Structuring Rental Property Portfolios

Residential landlords face strict statutory habitability and safety duties under the Ohio Landlord-Tenant Act (Ohio Rev. Code § 5321.04), alongside lead paint, slip-and-fall, and dog-bite claims. By placing each single-family home or small multi-family building into its own designated series (for example, Buckeye Holdings LLC, Series 1 for a Lakewood duplex and Buckeye Holdings LLC, Series 2 for a Short North fourplex), a premises liability lawsuit at one address cannot touch the rental income or equity of your other properties.

House Flipping Entities

Active rehab and fix-and-flip projects carry elevated legal and tax risks, including general contractor disputes, mechanic's liens under Ohio Rev. Code § 1311.02, construction site injuries, and post-sale buyer defect lawsuits. Even worse, from a federal tax perspective, mixing active house flips (which the IRS classifies as dealer inventory subject to ordinary income and self-employment taxes) inside the same entity as long-term buy-and-hold rentals can taint the capital gains treatment of your entire portfolio. Isolating each flip or active development project into a dedicated series ring-fences both construction liability and tax characterization.

Commercial Real Estate Holdings

Investors acquiring neighborhood retail strips, industrial warehouses, or office buildings often bring in different passive joint-venture partners for each deal. Under Ohio Rev. Code § 1706.76(A)(2), each series must have at least one member associated with it, allowing you to admit Co-Investor A into Series 1 (a Dayton warehouse) with a 70/30 profit split while admitting Co-Investor B into Series 2 (a Columbus retail plaza) with a 50/50 split-all governed under one master Series LLC framework. Note, however, that institutional commercial lenders and CMBS underwriters sometimes require a standalone Single Purpose Entity (SPE) rather than an internal series for high-leverage commercial loans.

Step-by-Step Process to Form an Ohio Series LLC

Setting up a legally enforceable Series LLC requires far more precision than forming a standard LLC. Follow these five mandatory steps:

Step 1: File Form 610 (Formerly Form 533A) with the Statutory Series Notice

File Form 610, Ohio, Secretary of State, Articles of Organization for a Domestic Limited Liability Company (historically indexed as Form 533A, Ohio, Secretary of State, Articles of Organization for a Domestic Limited Liability Company) with the Ohio Secretary of State, Columbus. Pursuant to Ohio Rev. Code § 1706.16(A)(3) and Ohio Rev. Code § 1706.763, you must include the statutory notice in the Purpose / Additional Provisions section stating that the LLC may establish one or more series of assets subject to the liability limitations of Ohio Rev. Code § 1706.761. Without this exact notice on public file, your internal series shields are invalid.

Step 2: Draft a Master Series Operating Agreement and Series Supplements

Unlike states that require a separate public filing for each series, Ohio creates individual series privately through your operating agreement under Ohio Rev. Code § 1706.76(A). Your Ohio real estate attorney will draft a Master Operating Agreement containing the mandatory Ohio Rev. Code § 1706.761 liability limitation clauses, along with a separate Series Designation Supplement for each property you acquire.

Step 3: Obtain Separate EINs and Register Ohio Trade Names

Under proposed IRS regulations, each series is treated as a separate entity for federal tax purposes depending on its ownership structure. Most real estate investors obtain a separate EIN for each series from the Internal Revenue Service, Cincinnati using Form SS-4, FED, Internal Revenue Service, Application for Employer Identification Number. Additionally, to help banks and county title offices recognize the series name, many attorneys file Form 534A, Ohio, Secretary of State, Name Registration ($39 fee) to register a fictitious name or trade name for each series.

Step 4: Open Separate Bank Accounts and Accounting Ledgers for Each Series

This is the single most critical compliance rule for an Ohio Series LLC. Under Ohio Rev. Code § 1706.761(B)(1) and Ohio Rev. Code § 1706.762(B), the liability shield protecting one series from another evaporates if you fail to account for each series' assets separately:

• Dedicated Bank Accounts: Open a separate commercial checking account and security deposit account for every individual series. Never deposit rent checks from Series A into the bank account of Series B or the Master LLC.
• Separate Accounting Books: Maintain distinct balance sheets and profit-and-loss ledgers in your accounting software for each series, and execute formal written inter-series loan agreements if the Master LLC advances capital to a series.
• Contract and Lease Execution: Always sign leases, property management agreements, and contractor bids in the exact legal name of the specific series (e.g., John Doe, as Manager of ABC Properties LLC, on behalf of Series 1 only).

Step 5: Record Deeds in the Series Name and Update Insurance

Under Ohio Rev. Code § 1706.762(A), real estate title may be held directly in the name of the designated series. Have your real estate attorney prepare and record a warranty or quitclaim deed with the county fiscal officer/recorder transferring each parcel into its specific series, and ensure every series is explicitly listed as a Named Insured on your commercial general liability and umbrella insurance policies.

How Much Does an Ohio Series LLC Cost?

How Long Does It Take to Set Up a Series LLC in Ohio?

Filing the master Articles of Organization with the Ohio Secretary of State, Columbus takes 3 to 7 business days via standard service, 2 business days for a $100 expedite fee, 1 business day for a $200 expedite fee, or 4 business hours for a $300 walk-in expedite fee. Best of all, once your Master Series LLC is approved and your attorney drafts your Master Operating Agreement, creating a brand-new series for a future property acquisition takes less than 1 hour because it is executed privately via an internal Series Supplement without waiting on state processing.
