A period during which a tenant pays reduced or no rent, typically granted at lease commencement as a concession in exchange for signing a long-term lease or completing tenant improvements.
Rent abatement is one of the most common landlord concessions in a soft leasing market. It is distinct from a free rent period in that abatement can be partial (e.g., 50% of base rent) while free rent is a full waiver. Many leases include claw-back provisions: if the tenant defaults during the lease term, the abated rent becomes immediately due. Tenants should confirm whether abatement applies to base rent only or also to operating expenses and other charges. The net effective rent calculation must account for abatement to compare deals accurately.

Landlords most commonly grant rent abatement at the beginning of a lease term to compensate tenants for build-out time and the delay before generating revenue from the space. Free rent periods typically range from 1 to 3 months for small retail spaces and 3 to 6 months for larger office and industrial spaces. Rent abatement is also granted as a concession in weak leasing markets to attract tenants, and occasionally during lease renewals to prevent tenants from relocating to competing properties.
Not all rent abatement is structured as a true waiver. Some landlords structure "free rent" as deferred rent that becomes immediately due if the tenant defaults or terminates the lease early — this is fundamentally different from a genuine abatement. Tenants should verify that the abatement clause uses language like "rent is waived" or "no rent shall be due" rather than "rent is deferred" or "rent is forgiven subject to the following conditions." A conditional abatement can create a hidden acceleration liability of tens of thousands of dollars.
During lease abstraction, rent abatement periods must be captured as specific date ranges with the exact amount of rent waived (base rent only versus base rent plus operating expenses). The abatement affects the calculation of net effective rent — the true annualized cost after spreading the free rent concession over the entire lease term. A 3-month free rent period on a 5-year lease at $30,000 per month reduces the net effective rent from $30,000 to $28,500 per month, a 5% reduction that materially affects lease-versus-lease comparisons.
