Silicon Valley Office Market Rebounds in Early 2025—Here’s What Smart Investors Should Know

After several quarters of uncertainty, Silicon Valley’s office sector is showing signs of life—and for investors, that’s not just good news... it’s an opportunity.

The latest Q1 2025 report from Colliers reveals positive momentum in Santa Clara County and Fremont. And while recovery won’t happen overnight, there are clear signals that investor confidence—and tenant activity—is returning.

Here’s what we’re seeing and how you should respond:

📉 Vacancy Rates Show Modest Improvement

The Silicon Valley office vacancy rate dropped to 16.4% in Q1 2025, down from 16.6% at the end of 2024. While it’s still slightly higher than Q1 2024’s 16%, this shift marks a stabilization trend after a bumpy few years.

🧠 Investor Insight: This kind of incremental improvement often precedes larger movements. It’s a signal that smart money is starting to circle back into the market.

💰 Asking Rents Are Rising

The average office rent reached $5.41 per square foot—up from $5.36 at the end of 2024 and $5.35 this time last year. It’s a small but important trend that points toward renewed tenant demand.

📊 Why It Matters: Even slight upticks in rent can improve your cap rate and cash flow forecasts, especially in well-located Class A or flexible office spaces.

🔄 Sublease Inventory is Shrinking

One of the most telling signs of recovery? The amount of office space available for sublease is dropping:

• 4.3% in Q1 2025

• 4.7% in Q4 2024

• 5.5% in Q1 2024

This suggests that tenants are holding onto space again, rather than offloading it—indicating growing confidence in operations, headcounts, and long-term footprints.

🔍 What We’re Watching: This can lead to tighter supply and more aggressive competition for well-located space by year-end.
