With the high cost of living in Nairobi, many homeowners and long-term tenants are looking for ways to make extra money. Renting out a spare bedroom to a lodger is a quick way to pull in some steady income.

But bringing a stranger into a private living space is more than just collecting rent at the end of the month. It requires careful management of legal rules, tax obligations, and the daily reality of sharing a house.

Understanding the legal setup and KRA tax

Before looking for a housemate, understanding the formal rules is necessary. Relying on verbal agreements with a lodger is a recipe for trouble when misunderstandings happen.

A solid arrangement requires a written tenancy agreement that states the exact rent, how utility bills will be split, the house boundaries, and the notice period required if either party wants to end the arrangement.

A landlord and tenant sit at a simple table reviewing a written tenancy agreement together.

Landlords must also account for the taxman. Any money received from a lodger is considered rental income by the Kenya Revenue Authority.

Under Kenyan tax laws, residential rental income between Sh288,000 and Sh15 million a year attracts a flat tax rate of 7.5 per cent on the gross amount received. This tax must be declared and paid through the iTax portal on or before the 20th day of the following month to avoid heavy penalties.

Screening housemates and setting boundaries

Sharing a kitchen, bathroom, and living room with someone new changes how a home functions.

Research by the International Institute for Environment and Development notes that “Nairobi’s informal renters find their access to shelter is not only affected by their financial status, but by a range of social factors including age, household size, and gender norms.”

This means personal habits, cultural backgrounds, and social expectations will directly affect how peaceably people live together.

In a shared kitchen, a landlord explains the boundaries and usage rules to a new tenant.

To keep things smooth, vetting potential lodgers thoroughly is vital. Helpful steps include asking for a copy of a national identity card, proof of regular income, and references from previous places.

Once the right person is found, agreeing on clear house rules from the start prevents friction. These rules should cover noise levels, cleaning duties, and expectations around overnight guests.

Treating the arrangement as a professional business setup keeps the home peaceful while securing a financial boost.
