TIC and Fractional Ownership Risks for Kearny Mesa San Diego Office Buildings in 2026

What are the real tenant-in-common and fractional ownership risks I need to understand before buying a commercial office building in Kearny Mesa, San Diego, in 2026?

TIC and fractional ownership structures for commercial office buildings carry serious risks including joint liability for the full mortgage, IRS reclassification that can destroy your 1031 exchange benefits, decision deadlock with co-owners, and near-zero liquidity if you need to exit.

Why Kearny Mesa Office TIC Risks Deserve Your Full Attention Right Now

If you’re considering a tenant-in-common or fractional ownership stake in a Kearny Mesa office building, you’re walking into one of the more nuanced corners of San Diego commercial real estate. And right now, the timing makes it even more complex.

Here’s the tension: Kearny Mesa is actually performing well relative to the broader San Diego office market. As of Q2 2026, Kearny Mesa posted an 8.1% vacancy rate and 11.1% availability rate across its roughly 11.3 million square feet of office inventory, according to market data tracked by Hughes Marino. That’s meaningful, because the countywide office vacancy rate sits at 13.9% as of Q3 2026, per Pacific Coast Commercial’s San Diego market report. Downtown San Diego is at a staggering 34% vacancy.

So Kearny Mesa looks attractive on paper. But the TIC structure itself introduces a layer of risks that have nothing to do with the submarket’s health, and everything to do with how you hold the asset. Having closed over 275 transactions and worked in San Diego real estate for 18 years, I can tell you that the ownership structure matters just as much as the building itself. A cloudy mind can’t make decisions, so let me walk you through this clearly.

Joint and Several Liability Could Cost You Everything in Kearny Mesa

This is the risk I want you to understand before anything else. In a TIC arrangement, co-owners share joint and several liability over the mortgage and property taxes. What does that actually mean for your wallet?

It means a lender or taxing authority can pursue any individual co-owner for the entire outstanding amount, regardless of your percentage share. If you own 15% of a Kearny Mesa office building and your co-owners default, you could be on the hook for 100% of the debt. According to CommercialRealEstate.Loans, if two out of three tenants in common go bankrupt and refuse to pay their share of property taxes, the remaining solvent tenant could be forced to foot the entire bill.

You might negotiate cost-sharing provisions into your TIC agreement for repairs, insurance, and maintenance. But the mortgage and tax obligations run deeper than any private contract between co-owners. Your TIC agreement doesn’t override what a lender can legally demand from you.

Consider what this looks like in practice. The San Diego office market is experiencing what Hughes Marino describes as the worst conditions in 30-plus years. Even though Kearny Mesa is one of the tightest submarkets in the county, your co-owners might hold interests in other struggling properties or face financial pressures you can’t predict. Their financial health directly impacts yours.

IRS Reclassification Risk Can Destroy Your San Diego 1031 Exchange

For many investors, the entire reason for entering a TIC structure is to complete a 1031 exchange. You sold a smaller property, and now you’re looking at buying a fractional interest in a larger Kearny Mesa office building to defer taxes. Makes sense on paper, right?

Here’s where it gets dangerous. According to Seyfarth Shaw LLP, if the TIC arrangement is not properly structured and documented, the IRS may classify it as a partnership interest or a security rather than an interest in real estate. Section 1031 of the Internal Revenue Code expressly prohibits the exchange of investment property for partnership interests, stocks, bonds, notes, or other securities.

The IRS issued Revenue Procedure 2002-22 with 15 specific TIC requirements, which lays out strict criteria that distinguish a legitimate TIC from a partnership. Among the most critical:

• Unanimous consent is required for leases, mortgages, and major decisions
• Management agreements are limited to one-year terms that must be unanimously renewed
• No dilution of ownership is permitted when a co-owner misses a capital call (the IRS treats dilution as a hallmark of a partnership)

If your TIC crosses any of these lines, your entire 1031 exchange could be unwound, and you’d face the full tax bill you were trying to defer. When I work with commercial investors, this is the risk I spend the most time discussing because it’s the one that carries the highest financial consequence.

Decision Deadlock and Lease Concessions in Kearny Mesa

So how do you actually operate a building when every major decision requires unanimous consent from all TIC holders? This is where theory meets reality, and it gets messy.

Right now in San Diego, office landlords are offering extraordinary concessions. According to Hughes Marino’s 2026 market analysis, concession packages include up to 12 months of free rent on eight-year leases and fully funded tenant improvement allowances. If you own a TIC interest in a Kearny Mesa building, you and your co-owners need to unanimously agree on whether to match those concessions.

What happens when one co-owner refuses to approve competitive lease terms? Your building loses tenants to the property across the street. Kearny Mesa posted 67,546 SF of positive net absorption in Q2 2026, which tells you tenants are moving into the submarket. But they’re moving into well-managed buildings that can respond to market conditions quickly. A TIC structure makes fast decisions nearly impossible.

The Management Agreement Trap

Remember, the IRS limits property management agreements to one-year terms. Every year, all co-owners must unanimously renew the management contract. If even one co-owner disagrees with the property manager’s performance or fees, you’re renegotiating or searching for a new manager while the building’s operations hang in the balance.

Liquidity Risk Is Real, and the San Diego Office Market Makes It Worse

You need to understand this plainly: there is no active secondary market for TIC interests. When you want to exit, you need to find someone willing to buy a fractional ownership stake in a specific commercial property. That’s a much smaller buyer pool than for a whole building.

Now layer on the current market conditions. San Diego’s office sector has seen approximately 11 high-rise office buildings in downtown go through foreclosure or forced sale, per Hughes Marino. While Kearny Mesa is healthier, potential buyers of your TIC interest will evaluate their purchase against the backdrop of the broader market. A recent CBRE transaction at 9320 Chesapeake Drive in Kearny Mesa closed at $4.8 million in August 2026 for a whole building, and the buyer was a 1031 exchange buyer who wanted the entire asset, not a fractional slice.

Selling your fractional interest could take years. And if you’re forced to sell at a discount to attract a buyer, you may lose more than you saved on the original tax deferral.

Partition Actions and Uncontrolled Ownership Transfers in San Diego

What happens when co-owners disagree about whether to sell? Any co-owner can file a partition action in court, which can force a sale of the entire property, even if you want to hold. According to multiple legal analyses, partition actions can result in the physical division of the property or, more commonly for commercial buildings, a forced sale at auction.

The reverse is equally concerning. If a co-owner passes away without a designated heir, their ownership share could enter probate court, creating uncertainty for everyone. If a co-owner decides to sell or transfer their share independently, you could end up with a new co-owner you never chose and whose investment goals conflict with yours.

Frequently Asked Questions

What makes Kearny Mesa different from other San Diego office submarkets for TIC investments?

Kearny Mesa posted an 8.1% vacancy rate in Q2 2026, making it one of the two tightest office submarkets in San Diego County, per Hughes Marino data. Its central location, freeway accessibility, and in-person industries contribute to stronger fundamentals than downtown San Diego’s 34% vacancy. However, strong submarket performance does not eliminate the structural risks of TIC ownership itself.

Can a TIC interest qualify for a 1031 exchange in California?

Yes, but only if the arrangement strictly satisfies the 15 requirements in IRS Revenue Procedure 2002-22. If the structure resembles a partnership (through shared management, dilution provisions, or multi-year management contracts), the IRS may reclassify it and disqualify the exchange, according to Seyfarth Shaw LLP and Olshan Frome Wolosky LLP legal analyses.

What is joint and several liability in a TIC?

It means a lender or taxing authority can pursue any single co-owner for the entire debt, not just their proportional share. Per CommercialRealEstate.Loans, if your co-owners default on the mortgage or property taxes, you could be personally liable for the full amount regardless of your percentage of ownership.

How hard is it to sell a TIC interest in a San Diego office building?

Very hard. There is no active secondary market for TIC interests in commercial real estate. You must find a buyer willing to accept a fractional ownership stake, which significantly narrows your pool. In the current San Diego office market, which Hughes Marino describes as the worst in over 30 years, this liquidity challenge is amplified.

What is a partition action and can it force me to sell?

Yes. Any co-owner can file a partition action in court to force a division or sale of the property. For commercial office buildings, this typically results in a court-ordered sale. Even if you want to hold, the court may override your preference if a co-owner demands it.

How does the unanimous consent requirement affect building operations?

Every major decision, including leases, refinancing, and capital improvements, requires agreement from all TIC holders. In a market where landlords are offering up to 12 months of free rent as concessions (per Hughes Marino’s 2026 analysis), inability to approve competitive terms quickly can result in lost tenants.

What happens if a TIC co-owner dies or goes bankrupt?

Their interest may pass to heirs through probate or be liquidated through bankruptcy proceedings. You could end up with a new co-owner whose investment timeline and goals differ sharply from yours, with limited ability to prevent the transfer.

Are there financing challenges specific to TIC office buildings?

TIC structures create complications with lenders. Many commercial lenders are reluctant to finance fractional interests because of the shared liability and governance complexity. You may face higher interest rates, larger down payments, or difficulty refinancing compared to sole ownership.

How does San Diego’s current office vacancy rate affect TIC exit strategies?

San Diego office vacancy reached 14.3% in Q1 2026 with total availability at 19.5%, per Hughes Marino. While Kearny Mesa outperforms countywide averages, the broader market softness depresses valuations and makes finding TIC buyers even more difficult.

Should I hire an attorney before entering a TIC arrangement for a Kearny Mesa building?

Absolutely. The TIC agreement, the management structure, and the IRS compliance requirements all demand specialized legal review. The consequences of a poorly structured arrangement include full tax liability from a failed 1031 exchange, unexpected personal liability, and potential forced sale of the property.

The Bottom Line

TIC and fractional ownership structures can serve a purpose, particularly for 1031 exchange investors who need to match a specific acquisition price. But for a commercial office building in Kearny Mesa, San Diego, in 2026, the risks are substantial and layered. Joint liability, IRS reclassification, illiquidity, decision deadlock, and forced sales are not theoretical concerns; they are documented realities of how these structures operate.

Kearny Mesa’s relative strength in the San Diego office market does not insulate you from these structural risks.
