If you are weighing a warehouse for rent in San Diego, it helps to understand the market you are entering. San Diego industrial is shaped by one fact above all others: there is very little room to build. The county is boxed in by the Pacific, the Mexican border, Camp Pendleton, and the mountains, which keeps supply tight and rents among the highest in the state outside the Bay Area. This overview covers rents, vacancy, where supply is growing, and how the submarkets differ, so you can budget and target your search with real numbers.

Rent and Vacancy at a Glance (2026)

  • Average asking rent: around $1.58/SF per month NNN countywide (Colliers, Q2 2026). Rates are quoted per month in San Diego, so that is roughly $19/SF per year.
  • Overall vacancy: near 7.3% (Cushman & Wakefield Q1 2026); other brokerages tracking a larger inventory set report figures closer to 9 to 10%. The methodologies differ, so treat the exact number as directional, the direction being a softer, more tenant-friendly market than the frenzy of a few years ago.
  • Trend: the market has moved through a correction. New deliveries, especially in Otay Mesa, have pushed vacancy up from record lows and nudged asking rents off their peak. For tenants, that means more choice and more room to negotiate than the market offered in 2022 to 2024.

Why San Diego Is Different

Most California industrial markets are about land and highways. San Diego is about constraint and specialization:

  • Supply is genuinely scarce. Limited developable land keeps a floor under rents even when demand cools. Do not expect inland-California pricing here.
  • The border drives the big-box story. Otay Mesa is the county’s distribution engine, tied directly to manufacturing in Tijuana. Nearshoring and cross-border trade keep demand for large distribution and cross-dock space alive.
  • Specialized tenants dominate. Life sciences, defense, and advanced manufacturing take a large share of flex and R&D space, particularly in the coastal North County and the Sorrento Mesa / Miramar corridor. That pushes flex rents up and keeps quality space tight.

Where Supply Is Growing

Almost all of the county’s near-term construction is in Otay Mesa, where large distribution projects continue to deliver. For a tenant needing 50,000 SF and up of modern distribution space, Otay Mesa is where the newest options and the most negotiable deals are. Elsewhere in the county, new construction is limited, so the central and coastal submarkets stay tight even as the headline vacancy number rises.

Submarkets in Brief

  • Otay Mesa: big-box distribution, cross-border logistics, best value for large space. Our Otay Mesa cross-border guide goes deeper.
  • Miramar / Mira Mesa: the largest inventory in the county, a broad mix of distribution, flex, and manufacturing.
  • Kearny Mesa: central, dense with multitenant and flex space, convenient for last-mile.
  • Chula Vista / National City: South Bay, distribution and port-adjacent users.
  • El Cajon / East County: smaller-bay, service-industrial, lower rents.
  • North County (Carlsbad, Vista, San Marcos, Escondido, Oceanside): everything from premium Carlsbad R&D to value-priced inland flex and manufacturing.

What This Means If You Are Searching

  • Budget per month, not per year, and always on total occupancy cost including the NNN load.
  • Use the softer market. With vacancy off its lows, there is more negotiating room on rate, free rent, and tenant improvements than there was a few years ago, especially for larger distribution space.
  • Target by tenant type. Distribution users should start in Otay Mesa and Miramar; flex and R&D users in Carlsbad, Sorrento Mesa, and Miramar; small-bay and service users in Kearny Mesa, El Cajon, and inland North County.

Frequently Asked Questions

What is the average warehouse rent in San Diego in 2026?

Around $1.58 per square foot per month NNN countywide (Colliers, Q2 2026), or roughly $19/SF per year. Rates range from about $1.20/SF/mo for Otay Mesa big-box and East County space up to $2.10/SF/mo for coastal North County R&D and flex.

Is San Diego industrial vacancy high or low right now?

Moderate and rising. Cushman & Wakefield reported about 7.3% countywide in Q1 2026; firms tracking a larger inventory set report closer to 9 to 10%. Either way the market has loosened from its record-tight lows, which favors tenants.

Where is new warehouse space being built in San Diego?

Almost all near-term construction is in Otay Mesa, where large distribution projects keep delivering. Most other submarkets see little new supply, which keeps them tight.

Why is San Diego warehouse rent so much higher than inland California?

Limited developable land. The county is constrained by the ocean, the border, Camp Pendleton, and the mountains, so supply stays scarce and rents hold well above inland markets like the Inland Empire or Central Valley.
