Why expansion rights matter
Industrial tenants grow. Growth shows up in operations as the need for more space — often a need that exceeds the building you're sitting in. The question is whether your existing landlord is contractually obligated to give you that space at terms you can live with, or whether you have to relocate.
Relocation is expensive. Moving a distribution operation costs 2–4 months of revenue (lost productivity during the move) plus 1–2x annual rent in direct moving costs (racking, conveyors, IT, fit-out). For most tenants, staying in place during growth is dramatically cheaper than moving — if the lease lets you.
That's what an expansion right is for. The problem is that most expansion rights, as written in standard leases, don't actually work when you try to use them.
The four common failure modes
1. The "right of first refusal" trap
A right of first refusal (ROFR) says: if the landlord receives a bona fide offer to lease adjacent space from a third party, you have the right to match. It sounds protective. It isn't.
In practice, the landlord controls when and whether to market the space. They can sit on vacant space for 18 months while they "market" it, then accept an offer from a related party at terms that favor them. By the time you see the third-party offer, you have 5–10 business days to match — at which point you're matching a number that may have been engineered specifically to be unmatchable.
A ROFR is theater. It almost never produces a fair outcome for the tenant. If your "expansion right" is a ROFR, you don't have an expansion right.
2. "At market terms" without a methodology
Many expansion rights specify pricing as "at then-market terms" or "at the prevailing market rental rate." This sounds reasonable. It isn't.
"Market" is whatever the landlord says it is. They produce a CoStar comp set heavily weighted to deals that favor their position. You produce a comp set heavily weighted to deals that favor yours. The two sides don't agree, the option expires, and you're forced to move.
The functional expansion right specifies methodology: the lower of (a) the average of the three most recent leases signed in the building, normalized for SF, or (b) the published asking rate for the subject space at the time of exercise, minus standard concessions. The methodology has to be objective enough that a third party could compute the answer without involving either party.
3. No specified expansion space
"Tenant shall have the right to expand into available space within the building" is unenforceable. Which space? When? How much? If the building has 50,000 SF available scattered across three non-contiguous suites, do you have the right to one of them, all of them, or whichever the landlord prefers to offer?
The functional expansion right names the space — by suite number, square footage range, and adjacency to your existing premises. The landlord knows exactly what they're committing. You know exactly what you're getting.
4. No timing structure
"Tenant may exercise the expansion option upon written notice" is unenforceable in a different way. When can you exercise? For how long does the option remain available? If you don't exercise by month 36, does the option expire? Or does it remain perpetually live? What happens if you exercise but the existing tenant in the adjacent space won't vacate?
The functional expansion right specifies windows. Typically: a notice period of 6–12 months in advance, a delivery date for the expansion space (with landlord obligation to recapture from any existing tenant if necessary), and either a specified exercise window or a perpetual right (clearly stated).
What "actually works" looks like
Here's a sketch of an expansion right that protects you. Adapt to your specific situation, but these elements need to be present:
Tenant shall have a continuing right to lease Suite [B] (approximately 60,000 SF, contiguous to Tenant's current premises, as shown on Exhibit [G]) at any time during the Term upon 9 months prior written notice to Landlord. Landlord shall deliver Suite [B] to Tenant no later than the date specified in the notice, free of any existing tenancy (Landlord at its sole expense recapturing the space from any existing tenant). Rent for the expansion space shall be the lower of (a) Tenant's then-current base rent per square foot in the existing Premises, or (b) the average per-square-foot base rent of the three most recent comparable leases signed in the Building during the preceding 12 months. Landlord shall provide an expansion tenant improvement allowance of [$X per square foot]. The expansion Term shall be coterminous with the existing Lease Term.
Read that carefully. Every element exists for a reason:
- Continuing right — not a single exercise window, so growth that happens in year 4 doesn't expire your option.
- Named suite with exhibit — no ambiguity about what space you're getting.
- 9 months notice — enough lead time for the landlord to recapture if needed.
- Landlord obligation to deliver vacant — landlord's problem, not yours, to deal with existing tenancy.
- Pricing methodology — objective, computable from data, not subject to "market" interpretation.
- TI allowance — the landlord can't make the expansion economically unviable by withholding fit-out capital.
- Coterminous — your expansion lease ends when your main lease ends, simplifying renewal.
What landlords will push back on
The negotiation around expansion rights is where most landlords push hardest. Expect resistance on three points specifically:
Recapture obligation
Landlords don't want to be obligated to evict an existing tenant to deliver your expansion space. Reasonable compromise: landlord obligation to use "commercially reasonable efforts" to recapture, with a cap on Tenant's notice triggering Landlord's right to delay delivery by up to 12 months (during which Tenant continues to operate in current premises).
TI allowance
Landlords don't want to commit to a TI allowance for hypothetical future space at today's lease signing. Reasonable compromise: TI allowance specified as a percentage of then-current building TI norms, or tied to a comparable building benchmark with annual adjustment.
Pricing floor
Landlords want a floor — they don't want the methodology to produce a rent below their underwriting. Reasonable compromise: methodology produces the rent, but with a floor of (current base rent + annual escalator × years elapsed). You're not asking for below-market rent. You're asking for transparent market rent.
The one piece of language to fight hardest for
If your negotiating capital runs out and you can only fight for one element of the expansion right, fight for objective pricing methodology. A vague expansion right with objective pricing is enforceable. A specific expansion right with vague pricing is not. The pricing methodology is the structural anchor — without it, every other element becomes negotiable at the moment of exercise, which is exactly when your leverage is at its lowest.
Said differently: the expansion right works the day you exercise it. Everything else in the lease is a setup for that single moment. Make sure the structure favors you when you're standing in it.
