What is a letter of intent (LOI) in industrial real estate?
By Michael Law, Industrial Real Estate Broker · Updated June 06, 2026
Quick answer
A letter of intent (LOI) in industrial real estate is a non-binding document that outlines the key business terms a tenant and landlord have agreed to in principle before a formal lease is drafted. It covers the essential deal points — rent, term, free rent, TI allowance, options — and signals mutual intent to proceed to a binding lease. While generally non-binding on the business terms, LOIs often include binding exclusivity or confidentiality provisions.

- Stage at which most GTA industrial lease commercial terms are finalized: Letter of intent — before formal lease drafting begins (Michael Law — GTA Industrial Lease Benchmarks 2026)
What is a letter of intent (LOI) in industrial real estate?
A letter of intent is a preliminary document exchanged between a prospective tenant and a landlord that summarizes the key commercial terms of a proposed lease transaction. In the GTA industrial market, the LOI is the standard mechanism for reaching business-level agreement before spending legal fees on a full lease draft. The LOI defines the deal's economic framework — if the parties cannot agree on the LOI terms, the transaction ends before either side incurs significant legal cost. A typical GTA industrial LOI covers: the premises (address, unit, square footage), proposed lease commencement and expiry dates, base rent per square foot for each year of the term, free rent period (if any), tenant improvement allowance (if any), renewal options, permitted use, parking allocation, and basic landlord and tenant work obligations. Some LOIs also address assignment and sublease rights, personal guarantee requirements, and key landlord consent provisions. The LOI is generally non-binding on its commercial terms — either party can walk away from the transaction at any point before a formal lease is signed. However, most industrial LOIs include specific binding provisions: an exclusivity period (typically 30 to 60 days) during which the landlord agrees not to negotiate with other prospective tenants while the lease is being drafted, and a confidentiality provision protecting the deal terms from disclosure. A breach of the exclusivity provision can give the tenant grounds for a damages claim even though the LOI itself is non-binding. From a negotiating strategy perspective, the LOI is the most important document in the transaction — not the lease itself. The commercial terms established in the LOI will be reflected in the lease, and landlords are far more willing to negotiate rent, free rent, and TI allowances at the LOI stage than after the lease has been drafted. Once the LOI is signed and the tenant has invested time in lease review, the tenant's negotiating leverage diminishes. Pushing hard at the LOI stage on rent, options, and landlord work is the right approach. Tenants should also be aware that accepting a landlord's standard form LOI without modification can inadvertently lock in unfavorable terms. Key items to negotiate in any GTA industrial LOI include: a clear TI allowance with specified delivery conditions, a broad permitted use definition, renewal options at fair market value with a defined cap, and exclusions from CAM for capital expenditures.

Other questions about this
Is an LOI legally binding?
Generally, no — the commercial terms in an industrial LOI (rent, term, TI allowance, options) are non-binding and either party can withdraw before a formal lease is signed. However, specific provisions within the LOI — most commonly the exclusivity period and confidentiality clause — are typically drafted as binding and enforceable. Tenants and landlords should read LOIs carefully to identify which provisions are intended to be binding.
Should I use a broker to negotiate an industrial LOI?
Yes, always. An experienced industrial broker will identify market-standard terms, flag above-market demands from the landlord, and negotiate free rent, TI allowances, and renewal options that an unrepresented tenant would typically not secure. Broker fees in commercial real estate are paid by the landlord — there is no cost to the tenant for using an experienced broker in an industrial lease transaction.
How long does it take to go from LOI to a signed lease?
In the GTA industrial market, the LOI-to-signed-lease timeline typically runs 4 to 10 weeks depending on the landlord, the complexity of the deal, and the pace of legal review. Institutional REIT landlords with standard lease forms move faster; private landlords negotiating bespoke lease terms can take longer. The exclusivity period in the LOI — typically 30 to 60 days — is designed to protect both parties during this drafting window.

What is clear height in a warehouse or distribution centre?
Clear height in a warehouse or distribution centre refers to the usable vertical space from the finished floor to the lowest overhead obstruction — typically the bottom of the roof structure, sprinkler heads, or HVAC equipment. It is the single most important building specification for warehouse tenants because it determines how many racking levels can be installed and therefore how much product can be stored per square foot of floor space.

CAM, or common area maintenance, refers to the costs a tenant pays — on top of base rent — for the upkeep and operation of shared areas in a multi-tenant industrial building. In a typical GTA industrial net lease, CAM is one component of the operating cost recovery alongside property taxes and building insurance, and is charged on a per-square-foot basis proportional to the tenant's share of the building.
