How Commercial Lease Rent Reviews Work in Kenya

A rent review clause in a Kenyan commercial lease typically operates on one of three bases: open market rental value as at the review date, a fixed percentage escalation (commonly 5% to 10% per annum or per review period), or an index-linked adjustment tied to an inflation measure. The mechanism will be stated in the lease, and the tenant's starting point is to read the clause carefully.

Open market rent reviews require the parties to agree on the current market rental value. Where they cannot agree, the lease usually provides for determination by an independent valuer or arbitrator. The valuer will consider comparable lettings in the same building, the same street, or the same submarket, adjusted for differences in floor level, fit-out, parking, and remaining lease term.

A common mistake by tenants is to accept the landlord's proposed rent increase without checking market evidence. Equally, landlords sometimes underestimate what the market will support and leave money on the table. Both parties benefit from instructing a registered valuer to provide an independent rental assessment before negotiations begin.

In Nairobi's CBD and Westlands, office rental rates have shown significant variation in recent years, with some buildings experiencing downward pressure due to oversupply while premium Grade A space in well-located buildings has held firm. The valuer's job is to identify where the specific property sits within this range, supported by verified letting evidence rather than headline asking rents.

For sitting tenants facing a review, the key dates to watch are the review notice period (usually 3 to 6 months before the review date) and any counter-notice requirement. Missing a counter-notice deadline can result in the landlord's proposed rent becoming binding without negotiation. A registered valuer can prepare a rental assessment, provide expert witness testimony if the matter goes to arbitration, and negotiate on the tenant's behalf.

It is worth noting that the Landlord and Tenant (Shops, Hotels and Catering Establishments) Act (Cap 301) provides security of tenure protections for certain business tenancies, including protection against unreasonable rent increases. Whether Cap 301 applies depends on the classification of the premises and the nature of the business — not all commercial leases are covered.
