TL;DR
- Sublease overhang has reshaped 2023–25 Class A pricing in major US gateway markets.
- Sublease product is typically 30–50% below direct landlord rent.
- Quality is highly variable — sublease space is rarely the trophy floor.
- Sublease term is short, limiting expansion and renewal optionality.
- Subleases can be the right answer for project teams, swing space, or 24-month bridge requirements.
Why the sublease wave matters
Post-2022, sublease availability spiked sharply in San Francisco, New York, Chicago, London, and Toronto as enterprise tenants right-sized after long-duration leases signed at the 2018–21 peak. Sublease overhang now exceeds 30% of total availability in several submarkets, and direct landlord rents have repriced down in response. The sublease bid stack is now the marginal pricing input.
Quality and term
Sublease space is rarely the trophy floor in the trophy building — it is what the original tenant overshot on. Floor plates are sometimes inefficient for the new occupant; furniture and fit-out">fit-out are often over-fitted to the prior tenant's brand. Term is short by definition (3–5 years typical), which constrains renewal economics and expansion.
When to take a sublease
Sublease is the right answer for project teams, M&A integrations, swing space, or 24-month bridge requirements. It is rarely the right answer for HQ deals where brand, expansion, and long-term economic certainty drive the decision.
How landlords are responding
Direct landlords are matching sublease pricing through expanded concession packages — typically 12–14 months free on a 10-year term in oversupplied submarkets. The all-in effective rent can reach parity with sublease pricing, while preserving direct-landlord term length and expansion optionality.
Frequently asked questions
- Will sublease availability normalise?
- Slowly. Most sublease space is on leases with 4–7 years remaining; full burn-off requires 5+ years of net positive absorption. Submarkets with strong AI / financial demand normalise faster.
- Can I extend a sublease?
- Sometimes. Direct landlord consent is required, and extensions often convert to direct leases at then-market terms. Negotiate a non-disturbance and a direct-landlord recognition agreement at sublease signing.
