New Hampshire Commercial Rent Increases & Escalation Clauses

Commercial landlords in New Hampshire operate in a completely unrestricted environment regarding rent pricing. There is no rent control for commercial properties, and the residential limitations imposed by RSA 540-B (such as the 30-day notice requirement and frequency cap) do not apply to commercial leases.

The only authority governing commercial rent increases is the written lease agreement.

No Statutory Restrictions

Unlike residential tenancies, there is:

• No cap on how much a commercial landlord can increase the rent.
• No mandatory notice period (unless the lease specifies one).
• No frequency restriction on how often rent can be adjusted during a lease term.

If a 5-year commercial lease is completely silent regarding rent increases, the rent remains flat for the entire 60-month term.

Common Escalation Methodologies

1. Fixed Percentage Increases (Stepped Rent)

The most common approach. The lease states that rent will increase by a predetermined percentage (typically 3% to 5%) annually on the lease anniversary.

2. CPI Escalations (Inflation-Tied)

The lease ties annual increases to the Consumer Price Index for the Boston-Cambridge-Newton metro area (the closest CPI index applicable to southern New Hampshire). This protects the landlord against inflation, but can result in very low or even zero increases during deflationary periods unless a "floor" clause is included.

3. Fair Market Value (FMV) Reviews

Typically reserved for lease renewal options. The new rent is reset to the "Current Fair Market Value" as determined by independent commercial appraisers. This ensures the rent aligns with real market conditions at the time of renewal.

4. Ratchet Clauses

New Hampshire landlords can include "ratchet clauses" in commercial leases, ensuring that if an FMV review determines the market rent has dropped, the rent cannot fall below the rate paid in the preceding year.

Drafting Strong Escalation Language

Because the lease is the only authority, vague escalation language is dangerous. A clause stating "Rent will increase annually at a reasonable rate" is nearly unenforceable. Precise, mathematical language is essential: "Base Rent shall increase by 3.5% on each anniversary of the Commencement Date."
