A figure quoted on a sale agreement is rarely the figure a buyer ends up paying over a decade of ownership. For apartment buyers in Nairobi, the gap between the advertised monthly service charge and its true lifetime cost is one of the consistently underpriced risks in residential real estate, and one of the least discussed before a sale agreement is signed.
What a Service Charge Actually Is, and Isn’t
A service charge is a periodic contribution, usually paid monthly, that every unit owner in a multi-unit development makes toward the cost of running and maintaining the building’s shared spaces and systems. It is neither rent nor a tax. It is a pooled contribution toward security, common-area cleaning, lifts, generators, water systems, insurance, and the administration that keeps a shared building functioning.
In law, the obligation to pay is tied to a unit’s ownership, not its occupancy. If a unit is rented out, the landlord remains liable for the service charge even where the tenant is the one making the payment in practice. This is the first point first-time buyers miss: a service charge is not a discretionary extra. It is a recurring, legally enforceable cost of ownership that continues for as long as the unit is held.
The Law Behind the Levy: The Sectional Properties Act, 2020
Service charges in Kenya’s apartment market are now governed by the Sectional Properties Act, 2020, which replaced the older 1987 Act and substantially strengthened the governance framework around shared buildings. Under the 2020 Act, a management corporation, made up of every unit owner, is automatically established the moment a development’s sectional plan is registered.
The Act required that a corporation maintain two distinct funds: an administrative fund for day-to-day running costs such as cleaning, security, and utilities for common areas, and a reserve fund, commonly called a sinking fund, ring-fenced for major capital expenditure such as lift overhauls, roof replacement, and repainting. It also gives owners a clear right to request a written statement of the contributions due on their unit, which the corporation must provide within twenty days, and it replaces the old rent-tribunal route for disputes with an Internal Dispute Resolution Committee, with appeals heard by the Environment and Land Court.
What the Act does not do is set or cap the actual amount a service charge can be. Kenya has no regulator that standardizes service charge rates across developments. That leaves the figure entirely a function of each building’s own budget, the quality of its management, and how disciplined its corporation is about collecting from every owner, which is precisely why the same apartment type, in the same neighbourhood, can carry service charges that differ by a factor of five or more.
What Service Charges Actually Cost in Nairobi Today
Reported monthly service charges across Nairobi’s residential market range from roughly KSh 3,000 in lower-density satellite estates to KSh 25,000 and above in premium apartment buildings in areas such as Westlands and Kilimani, where lift maintenance, backup power, and contracted security push costs significantly higher than in walk-up developments.
Where the money typically goes in a mid-range Nairobi apartment building: security accounts for roughly 25–40% of the total service charge budget; common-area cleaning and grounds maintenance together account for a further 10–15%; the remainder covers generator fuel, water, and borehole pumping electricity, lift maintenance contracts, insurance, and management fees.
The Westlands Picture
Westlands carries one of the city’s highest concentrations of lift-equipped, generator-backed, borehole-served apartment buildings, a direct consequence of its position as a dense commercial and diplomatic corridor with high-rise stock. That infrastructure is what residents experience as convenience: reliable backup power, working elevators, and water pressure that does not depend on Nairobi City Water. It is also, mechanically, why the area’s service charges sit toward the upper end of the city’s range rather than the lower end. Buyers evaluating Westlands stock should expect, and budget for, service charge bands that reflect this infrastructure load, not the lighter cost structure of a walk-up estate elsewhere in the city.
Why Buyers Consistently Underestimate the True Cost
The Quoted Figure vs. The Lived Figure
A service charge quoted during a sales process is a budgeted figure, not a guaranteed one. In buildings where collection is weak, where a meaningful share of owners falls into arrears, the shortfall doesn’t disappear; it is either absorbed as deferred maintenance or eventually passed on to paying owners through a revised budget or a special levy. A buyer who is told a figure at the point of sale should ask not just what it is, but what proportion of owners are actually current on payment.
The Compounding Effect Over a Mortgage Term
Held flat, which it rarely is, given inflation, a service charge of KSh 30,000 a month adds up to roughly KSh 7.2 million over a twenty-year mortgage term: enough, on its own, to fund a second unit’s deposit several times over. Most buyers price a property’s purchase cost in detail and treat its running cost as an afterthought. Over the life of ownership, the running cost is frequently the larger number.
The Yield Erosion Investors Don’t Model
For investment buyers, this is where the service charge stops being a comfort issue and becomes a returns issue. Published rental yields in the Nairobi market are almost always gross figures. Once property management fees, typically 8-12% of rent, and service charges are deducted, net yield typically lands 1.5-3% points below the advertised gross figure. In some buildings, service charge alone consumes 15-20% of gross rental income. A unit advertised at a difference that compounds materially over a holding period.
The Sinking Fund Buyers Rarely Ask About
The most consequential blind spot is the one that’s the hardest to see at the point of sale: whether a building has a genuinely funded reserve. A sinking fund exists precisely so that predictable, large, periodic costs, such as a lift overhaul, a full repaint, a roof replacement, are paid for from money set aside over years rather than sprung on owners as a one-off special levy at the worst possible time. A building with an empty or underfunded reserve looks identical to a well-capitalized one on a sales walkthrough. The difference only becomes visible in the accounts, which is exactly why asking to see them before signing is non-negotiable.
Five Questions to Ask Before You Sign
These are reasonable, ordinary questions. A development with nothing to hide will answer them without friction. A reluctance to produce this information is, on its own, a meaningful data point.
How AYA Approaches Service Charge Planning
At Spectre by AYA on AU Close, Westlands Road, the administrative and reserve funds are structured at the planning stage of the development, not improvised after handover. Budgets are built around the building’s actual infrastructure, its lifts, backup power, and security requirements, and disclosed to buyers as part of the purchase process, not revised upward once owners have already moved in. The intention is straightforward: a service charge figure that is accurate at the point of sale should still be accurate a year after move-in. This approach reflects how AYA structures its developments more broadly, not a position specific to any single building.
The Bottom Line
A service charge is not a footnote on a sale agreement. It is an annuity that runs for as long as you own the unit, and in many cases, it is the single largest variable separating a property's advertised cost from its real one. The same diligence buyers apply to price per square metre, location, and title should apply here: ask for the numbers, ask for the accounts, ask for the reserve fund balance, before you sign, not after you've moved in.
