San Diego’s biotech real estate market just came off the worst correction in a decade. Companies that over-leased lab space from 2020 to 2022 are now managing subleases, writing down TI costs, and in some cases relocating entire operations. The lesson was expensive: don’t sign a long-term real estate commitment when your volume forecast is uncertain.
The supply chain team heard that lesson too. That is the problem.
Distribution infrastructure is not real estate. Managing finished goods inventory in San Diego — devices, consumables, safety stock, commercial product staged for hospital accounts and regional distributors — is a throughput and timeline problem. It is not a square footage problem. When supply chain teams apply real estate thinking to it, they either over-commit to warehouse space they cannot fill or they under-invest in distribution capability at exactly the moment a product launch or new health system contract requires it.
The distinction matters in practice. A lab lease is a 7-to-10-year commitment that funds a build-out tied to your manufacturing process. A warehousing arrangement for finished goods distribution should flex with your commercial program — expanding when you win a new hospital system account, contracting when a product hits end-of-life, converting from shared pallet storage to dedicated contract space when your volume stabilizes enough to justify the trade. These are not the same instrument and they should not be evaluated by the same team using the same criteria.

What the Distribution Problem Actually Requires
The supply chain managers who get this right ask a specific set of questions before they evaluate any vendor:
What does outbound actually look like today? Releasing pallets to a regional distributor twice a month is a different operational requirement than running scheduled lot-controlled releases to 14 hospital accounts with delivery windows. Know which one you have before you walk into a vendor conversation.
Where is your volume in its trajectory? A product that just hit commercial launch has a different storage profile than a product 18 months into a steady distribution program. The right warehousing model depends on where you are, not where you plan to be.
What will your QA team ask during an audit? For Class I and Class II devices, documented lot traceability, controlled receiving processes, and the ability to pull an order before it ships are not optional. Ask every vendor candidate to walk you through a specific example of how they handled a lot hold. An answer that sounds like a policy is not the same as an answer that names a specific outcome.

How much are you willing to pay for flexibility? Shared warehousing costs more per pallet than a dedicated space at scale. The premium buys you the ability to change your volume without a lease conversation. At some point in your commercial ramp that optionality stops being worth the premium. That is when you move to a contract model. The right partner offers both and lets you make that transition without switching vendors.
Three Ways Companies Actually Solve This
Sign a direct warehouse lease. This gives you control, dedicated space, and the ability to build out exactly what you need. It also gives you a 3-to-5-year commitment, a build-out cost, a staffing requirement, and a fixed overhead line that does not flex with your volume. San Diego industrial rents in Miramar are running $10 to $14 per square foot annually. That is real money on top of build-out, insurance, and headcount before a single outbound shipment leaves the dock. For a company in a stable commercial phase with predictable volume, a direct lease can make sense. For a company navigating a product launch, a funding cycle, or a distribution ramp, you are solving a variable problem with a fixed instrument.
Use a national 3PL with a San Diego node. The nationals have compliance infrastructure on paper. Many have FDA-registered facilities and documented processes for lot tracking and regulated product handling. They also have revenue minimums and account tiers. A mid-market device company running 400 to 800 pallet positions is not their priority account, and that shows when something goes wrong. The service-level language in their contracts is not the same as operational capability.
Use a regional asset-based 3PL. This is where most mid-market medical device and biotech distribution programs find a workable answer. A regional asset-based 3PL owns and operates the facility, carries real outbound capability, and can offer both shared pallet storage and dedicated contract space depending on where you are in your commercial ramp. The range of quality in this category is wider than in the other two. Due diligence matters more here, not less.
Why Asset-Based Matters in This Market
Asset-based is not a marketing claim. It means the company you are contracting with owns or directly operates the facility. There is no third-party operator running the warehouse on their behalf. When you call about a pallet that went out wrong, you are talking to the dock manager, not a customer service rep reading from a ticket system.
For distribution work with a lot of traceability requirements, this matters in a specific way. When an issue surfaces — a receipt discrepancy, a lot hold, an order that needs to be pulled before it ships — the speed and quality of the response depends on how close the account management layer is to the physical operation. At a brokered or asset-light 3PL, there are layers between your call and the dock. At an asset-based 3PL, there are fewer.
It also means the capacity they quote you is real. They are not brokering space in a facility they do not control. If they say 3,400 pallet positions are available, that is their building and those are their positions. You can walk the facility and verify it before you commit to anything.
Johnson Warehousing operates an asset-based facility in San Diego with 50,000 square feet of available space and 3,400 open pallet positions on the I-15 corridor.Contract warehousing programs andshared and public warehousing are both available, which means you can start with pallet-level storage during a ramp and convert to dedicated space when your volume supports it. Our3PL Logistics team handles outbound from the same building — no separate carrier relationship, no handoff between storage and distribution.

The San Diego Geography Matters More Than You Think
Where your warehouse sits in San Diego County affects both your inbound freight cost and your outbound delivery speed.
The Sorrento Valley and Miramar corridor is where most biotech and medtech companies are physically located. Proximity to that cluster matters for product releases, field rep restocking programs, and local delivery. Kearny Mesa is the high-concentration industrial zone for general distribution — well-positioned on I-15 and I-805 for regional outbound. Chula Vista and the Otay Mesa corridor are the relevant nodes for anything tied to cross-border supply chains or port-adjacent drayage.
For most commercial distribution programs, the I-15 corridor gives you the right combination of proximity to the life sciences cluster and access to the carrier network for outbound LTL into California, Arizona, and Nevada.

The Decision
Two situations. One answer for each.
You have product moving now and no distribution infrastructure in San Diego. Every week without a solution is a freight cost, a service gap, or an expedite.Short-term storage and shared pallet positions are available now. You do not need a long-term contract to start.
You are planning ahead for a commercial ramp or a new account that requires San Diego coverage. Evaluate the partner before the volume hits. The worst 3PL decisions in this market get made under deadline pressure.
Your lab real estate team is solving their problem. Distribution infrastructure is yours.
