How Much Does Office Space Cost in San Francisco? (2026 Guide)

The honest answer in 2026: less than at any point in the last fifteen years. San Francisco office vacancy has held above 30% since 2023, and rents have repriced accordingly. If your mental benchmark is 2019 — when Class A space in the Financial District asked $85–$100+ per square foot per year — throw it out. Here is what space actually costs today, and what drives the number.

2026 asking rents by product type

These are asking rents. Effective rents — what you actually pay averaged over the term — come in meaningfully lower once concessions are negotiated, which brings us to the most important point in this guide.

Asking rent is not the price

In a market with 30%+ vacancy, landlords protect their headline rent (it supports the building’s appraised value) and compete on everything else. On a typical 5-year Class A deal in 2026 we see:

• Free rent: 6–12 months of abatement on a 60-month term — an effective discount of 10–20% by itself.
• Tenant improvement (TI) allowances: $75–$150 per square foot for build-outs on longer terms, often enough to fully fund construction.
• Shorter terms and spec suites: pre-built suites with 3-year terms — unthinkable for Class A landlords in 2019.

A space asking $65 full service with 9 months free and a real TI package can net out in the low-$50s effective. That spread is exactly what tenant-side negotiation captures.

Full service vs NNN — compare the right numbers

Most SF office quotes are full service: taxes, insurance, building maintenance, and usually janitorial are bundled into the rate. Retail and industrial quotes are usually NNN, where you add $8–$15 per square foot of pass-through expenses on top of base rent. When comparing an office suite against, say, a retail-to-office conversion quoted NNN, always convert both to total occupancy cost. (Full breakdown in our NNN vs gross lease guide.)

What moves the number inside a building class

• Floor height and views: in the same tower, a view floor can carry a $15–$25/SF premium over a low floor.
• Condition: a “second-generation” suite with usable build-out saves TI money and often rents at a discount to shell space.
• Transit: buildings within two blocks of Montgomery or Embarcadero stations lease faster and hold rent better than the mid-Market fringe.
• Landlord health: buildings in loan workouts can be aggressive on rate but slow (or unable) to fund TI — worth knowing before you negotiate.

The sublease shortcut

If your team is under ~50 people and you can live with 1–3 year terms, the sublease market is the best value in the city: furnished, cabled, plug-and-play floors at $25–$45 per square foot — 30–60% below direct deals in the same buildings. The tradeoffs are sublessor credit risk and inherited lease terms, both manageable with proper screening.

Budget rule of thumb

At 125 square feet per person, a 20-person company leasing decent Class B at $38 full service pays roughly $7,900/month. The same team in a furnished SOMA sublease at $30 pays about $6,250/month with no furniture spend. In Class A at $65, about $13,500/month. Those are real 2026 numbers — and every one of them is negotiable downward with the right process.
