For decades, buying an apartment in Nairobi felt like a legal gray area. You paid millions of shillings for a three-bedroom unit in Kilimani or Kileleshwa, but what did you actually hold in your hands? Traditionally, you received a long-term sub-lease (usually for 99 years) carved out of a "mother title" held by the developer, alongside a share certificate in a shell management company.
If the developer defaulted on a loan or refused to hand over the reversionary interest (the ultimate ownership of the land once the lease expires), apartment owners were left stranded—holding titles they couldn't independently charge for bank loans or sell without tedious corporate approvals.
The Sectional Properties Act (No. 21 of 2020) completely overhauled this structure. It fundamentally transformed the real estate landscape by introducing the concept of absolute individual vertical ownership.
If you are planning on buying an apartment, townhouse, or office suite in Kenya, relying on outdated sub-lease structures is a severe legal risk. This guide breaks down what you actually own under the modern sectional property regime.
1. The Legal Paradigm Shift: Sub-Leases vs. Sectional Titles
To understand your rights as an apartment owner, you must grasp the difference between the old legal regime and the current framework enforced by the Ministry of Lands.
The Old Sub-Lease Regime (Pre-2020)
Under the old system, a developer bought a piece of land, built a block of 50 apartments, and retained the mother title. They issued sub-leases to buyers. Because the shared spaces—like the lifts, gym, parking lot, and structural walls—belonged to the developer or a management company controlled by the developer, buyers were at the mercy of arbitrary service charge hikes and incomplete project handovers.
The Sectional Properties Act Regime (Modern Standard)
The modern law mandates that individual units are completely delinked from the developer. When you buy an apartment, the original mother title register is closed permanently. The Ministry of Lands opens a brand-new, distinct register for every single unit in the building.
Instead of a sub-lease document, you receive a Certificate of Title (if the underlying land is freehold) or a Certificate of Lease (if the land is leasehold). This document is a unique, geo-referenced title deed for your exact airspace.
2. Anatomy of Sectional Ownership: What is Yours and What is Shared?
When you buy a piece of vertical real estate under the Sectional Properties Act, your ownership is legally split into two distinct parts:
1. The Section (Your Airspace)
You have exclusive, absolute ownership of your unit's internal parameters. Legally, your section boundaries are typically defined by the center of the structural walls, floors, and ceilings. Everything inside that box—the finishing, flooring, internal plumbing, cabinetry, and internal decorations—is entirely yours to manage, modify (subject to structural safety), or rent out.
2. The Common Property
The common property consists of every square inch of the development that does not fall within an individual unit. This includes:
- Foundations, structural pillars, exterior walls, and roofs.
- Hallways, staircases, elevator shafts, and entry lobbies.
- Shared amenities: swimming pools, gyms, boreholes, generator rooms, and waste treatment plants.
- Security infrastructure, guard houses, and perimeter fencing.
You own a proportionate, undivided share of this common property as a tenant-in-common with all other unit owners. The exact ratio of your shared ownership is determined by the floor area of your unit relative to the total square footage of all units combined. If you own a penthouse, your share of the common property (and consequently, your voting power and service charge contribution) will be higher than that of a studio apartment owner in the same block.
3. The Power of the Owners' Management Company (OMC)
Under the old regime, developers often ran management companies as personal cash cows long after the building was occupied. The Sectional Properties Act eliminates this by enforcing the automated creation of an Owners' Management Company (OMC).
How the OMC is Formed
The moment a developer registers a Sectional Plan (a highly detailed, geo-referenced architectural and structural survey authenticated by the Director of Surveys), an OMC is automatically incorporated by law.
Key Structural Pillars of an OMC
- Instant Membership: The moment your title deed for an apartment is registered, you automatically become a legal shareholder in the OMC. You cannot opt out.
- Handover Clauses: The developer must legally hand over the control of the common spaces and the financial books to the elected board of unit owners within a strictly defined window after a percentage of units are sold.
- The Legal Power of By-Laws: The OMC establishes rules governing the community. These are not casual guidelines; they are legally binding by-laws registered at the lands registry that regulate everything from pet policies and noise levels to short-term letting restrictions (like Airbnb rules in hot zones like Kilimani).
- Levying Power: The OMC has the statutory authority to draft annual budgets, establish an administrative fund, and collect mandatory service charges for repairs, security, insurance, and maintenance of the common amenities.
“Warning to Defaulters: Under the Act, if an owner refuses to pay their service charge, the OMC has the legal power to register a statutory caveat or financial charge against that individual unit's title deed—effectively blocking the owner from selling, renting, or refinancing the apartment until the debt is cleared.
4. The Mandatory Conversion Rule: What Investors Must Check
The law does not just apply to new buildings. It explicitly states that all long-term sub-leases registered before 2020 must be converted into sectional titles.
The Ministry of Lands has completely ceased the registration of old architectural-plan-based long-term sub-leases. If you are looking at an older apartment block in areas like Kileleshwa or Lavington that hasn't undergone conversion, your legal due diligence team must investigate the status immediately.
The Conversion Checklist for Buyers
If you are buying a resale apartment, ask the seller or developer for these core items to ensure compliance:
- The Registered Sectional Plan: Check if a licensed surveyor georeferenced the property and if it bears the official seal of the Survey of Kenya.
- Apportionment of Land Rent and Rates: Under the Act, the national land rent and county land rates must be split across units. You should receive an independent bill for your unit from the county government, protecting you from collective penalties if your neighbors default.
- The Closed Mother Title: Ensure that the original land title registry has been formally closed and individual unit registers are open.
5. The Apartment Buyer’s Due Diligence Matrix
Before signing an Agreement for Sale for any apartment in Nairobi, use this structural checklist to verify the legal standing of the development:
Document / Status Attribute
Verification Mechanism
What to Look For
Sectional Search
Run a digital check on ArdhiSasa using the specific unit number.
Confirm the seller's name matches the certificate of lease exactly and ensure no hidden bank charges exist on that specific block.
Zoning & Approvals
Cross-reference County Physical Planning permits.
Ensure the building does not exceed the permitted structural density or density zoning for that specific lane in Kilimani/Kileleshwa.
The OMC By-Laws
Request the registered rules from the management committee.
Look closely for restrictive clauses on commercial activities, balcony modifications, and short-term occupancy limits if you plan to run an Airbnb.
Service Charge Audit
Review the OMC's audited financial accounts for the past 2 years.
Check for major structural debt deficits, capital sinking funds for lift replacements, and history of major utility shortfalls.
6. Frequently Asked Questions (FAQ)
Can a developer block the formation of an Owners' Management Company?
No. The incorporation of the OMC is a statutory requirement triggered automatically upon the registration of the sectional plan. Any attempt by a developer to withhold management control or retain reversionary interest of common zones against the provisions of the Sectional Properties Act is a legal offense punishable by severe statutory fines.
What happens if the building is destroyed by a fire or natural disaster?
Because you own a proportional share of the common property as a tenant-in-common, the OMC is legally mandated to maintain a comprehensive commercial insurance policy for the entire structure (the shell and common assets). In the event of total destruction, the insurance payout is managed collectively by the OMC to rebuild, or distributed proportionally based on your sectional unit floor-area ratios.
Does the Sectional Properties Act apply to commercial office spaces and godowns?
Yes. The Act explicitly covers apartments, flats, townhouses, maisonettes, commercial office suites, and industrial go-downs. Any development where horizontal or vertical spaces are divided among multiple independent owners falls directly under this law.
Summary Action Protocol for Apartment Buyers
If you are currently shopping for an apartment in Nairobi's vertical suburbs, safeguard your capital by taking these immediate steps:
- Never sign an agreement for sale that references an old long-term lease structure unless a clear clause guarantees conversion to a sectional title before completion.
- Insist on reviewing the registered Sectional Plan to confirm the exact unit square footage matches the ground layout.
- Request a compliance clearance certificate from the active Owners' Management Company to verify that the specific unit has zero outstanding service charge debts.
By insisting on complete Sectional Properties Act compliance, you ensure that your vertical investment is a secure, legally protected, and highly liquid asset in Kenya's fast-growing property market.
