Commercial property management in New Hampshire operates in a dramatically different legal environment than the residential sector. While residential leases are constrained by RSA 540, 540-A, and 540-B, commercial leases are governed almost entirely by the written contract and general common-law principles.
There is no comprehensive "Commercial Tenancy Act" in New Hampshire. The doctrine of Freedom of Contract reigns supreme.

Key Differences from Residential Law
| Topic | Residential Rule | Commercial Rule |
|---|---|---|
| Security Deposits | Capped at 1 month / $100 (whichever greater) | No statutory limit |
| Eviction Notice | 7-day demand + 30-day notice to quit | Governed by lease; court process similar |
| Rent Control | None statewide | None statewide |
| Late Fee Grace Period | 15-day mandatory grace period | None; governed by lease |
| Disclosures | Owner identity, deposit location, lead paint | No mandatory statutory disclosures |
| Maintenance | RSA 48-A habitability standards | Governed entirely by the lease |
The Power of the Lease Agreement
In New Hampshire commercial real estate, if it's not in the lease, it doesn't exist.
Unlike residential tenants, commercial tenants cannot rely on:
- An implied warranty of habitability to force the landlord to repair a failing HVAC system.
- The 15-day late fee grace period.
- The security deposit cap of 1 month's rent.
Every right, obligation, repair burden, and financial penalty must be explicitly negotiated and drafted into the written lease agreement. A poorly drafted commercial lease exposes both parties to significant financial risk.
Commercial Evictions
While the specific notice periods and cure mechanisms are largely dictated by the terms of the lease, commercial evictions in New Hampshire generally follow the same District Court process as residential evictions. A landlord must file a Landlord and Tenant Writ and cannot execute a "self-help" lock-out.
However, commercial leases can contractually define shorter cure and notice periods than the 30-day standard imposed by RSA 540 on residential tenancies, provided the tenant has agreed to those terms in the lease.
