 What is the Cost of Building Rentals on Land in Kenya? A Complete Guide for Investors

Building rental property is one of the most common and profitable investments in Kenya’s real estate sector. Many landowners wonder how much it would cost to put up rentals—whether bedsitters, one-bedroom apartments, or multi-unit flats—on their land. The answer depends on several factors such as location, land size, type of rentals, construction materials, and the level of finishing you want.

This guide provides a comprehensive breakdown of the costs involved in building rentals in Kenya. It also explores different construction scenarios, financing options, and return on investment considerations. If you’re planning to transform your land into an income-generating rental property, this will give you clarity on what to expect.

Why Building Rentals is a Popular Investment in Kenya

Kenya faces a housing deficit of more than 200,000 units annually. The demand is especially high in urban and peri-urban areas where many Kenyans move in search of work, education, and business opportunities.

For landowners, putting up rentals has several advantages:

Steady cash flow: Rentals generate predictable monthly income.

Appreciating value: Property values generally rise over time.

High demand: Affordable units such as bedsitters and one-bedrooms are always in demand.

Flexible development: You can start small with a few units and expand later.

Long-term wealth creation: Rentals provide income for generations if managed well.

These benefits explain why many people who inherit or buy land immediately consider building rental units.

Key Factors That Influence Rental Construction Costs

The cost of building rentals on land in Kenya varies widely. Here are the main factors that determine the total cost of your project:

1. Location of the land

Building in Nairobi or Mombasa is more expensive compared to towns like Eldoret, Kericho, or Kakamega.

Accessibility of materials and labor also influences cost.

2. Size of the land

A 50×100 plot (approximately 1/8 of an acre) can hold:

8–12 bedsitters

6–8 one-bedroom units

4–6 two-bedroom units

Larger parcels allow for multi-storey apartments.

3. Type of rental units

Bedsitters are cheaper to build compared to one-bedroom or two-bedroom apartments.

Units with modern finishes cost more than basic housing.

4. Construction materials and finishes

Choices such as machine-cut stones vs. prefab panels will alter costs.

Finishes like tiles, roofing, and paint can either keep costs affordable or push them higher.

5. Professional fees

Architects, contractors, and engineers usually charge 6–12% of the project cost.

6. Building approvals and compliance

County government approvals, NEMA fees, and inspections also add to the total.

7. Financing method

A cash-built project may cost less than one financed with a bank loan, which adds interest.

Average Cost of Building Rentals in Kenya

The average construction cost in Kenya ranges between KSh 35,000 to KSh 60,000 per square meter, depending on design, location, and finishes.

Here’s a breakdown by unit type:

Unit Type Average Size (sqm) Cost Range (KSh) Units Possible on 50×100 Plot

Bedsitter 20–25 sqm 700,000 – 1.2M 8–12 units

One-Bedroom 30–40 sqm 1.2M – 2M 6–8 units

Two-Bedroom 50–60 sqm 2.5M – 3.5M 4–6 units

Multi-storey Flats Varies 15M – 50M+ 20–60 units+

Example: Cost of Building Rentals on a 50×100 Plot

Let’s look at a practical example. Suppose you have a 50×100 plot in Ruiru:

Option 1: Bedsitters

Build 10 bedsitters at 1M each = 10M

Rental income per unit: KSh 8,000/month

Total monthly income: KSh 80,000

Payback period: ~10–11 years

Option 2: One-Bedrooms

Build 8 one-bedrooms at 1.5M each = 12M

Rental income per unit: KSh 12,000/month

Total monthly income: KSh 96,000

Payback period: ~10 years

Option 3: Two-Bedrooms

Build 5 two-bedrooms at 3M each = 15M

Rental income per unit: KSh 20,000/month

Total monthly income: KSh 100,000

Payback period: ~12–13 years 

From this example, one-bedrooms often strike a balance between affordability for tenants and good ROI for landlords.

Location and Cost Differences

The cost of construction and expected rent vary across Kenya.

Nairobi: Highest costs (up to KSh 60,000 per sqm) but highest rental income. A one-bedroom can fetch KSh 15,000–25,000 depending on the estate.

Ruiru, Kitengela, Juja: Moderate construction costs but high rental demand due to universities and growing populations. Bedsitters and one-bedrooms are especially profitable.

Nakuru: Affordable construction, rising demand. A bedsitter can rent for KSh 6,000–8,000.

Mombasa: Coastal materials can be cheaper, but finishing is costly due to salty environment. Rental demand is high in Nyali and Bamburi.

Kisumu: Rapidly growing rental market with affordable construction costs.

Financing Options for Building Rentals

Few investors build rentals purely with savings. Financing options in Kenya include:

Bank loans: Mortgage or construction financing, though interest rates range 13–18%.

Saccos: More flexible and affordable lending, especially for salaried members.

Chamas and partnerships: Pooling resources to fund construction.

Incremental building: Starting small with a few units and expanding over time.

Return on Investment for Rentals

The return on investment (ROI) depends on build costs, rental income, and occupancy rates. On average:

ROI for bedsitters: 9–11% annually

ROI for one-bedrooms: 10–12% annually

ROI for two-bedrooms: 7–9% annually

ROI for multi-storey flats: 12–15% annually

A well-managed rental project pays itself off in 8–12 years, after which the income becomes largely profit.

Common Mistakes to Avoid

Many rental developers make costly mistakes, including:

Underestimating total construction costs.

Choosing the wrong unit type for the market.

Ignoring professional input (architects, engineers).

Over-financing with high-interest loans.

Poor tenant management, leading to high vacancy rates.

Final Thoughts

Building rentals on land in Kenya is one of the best ways to create long-term wealth and financial stability. The total cost depends on location, unit type, and materials, but on average, expect to spend between KSh 10M–20M on a 50×100 plot for 6–12 units.

If you plan carefully, secure affordable financing, and build according to market demand, your rental property can pay itself off within a decade while continuing to appreciate in value.

For anyone looking to turn land into a steady income stream, understanding the cost of building rentals is the first and most crucial step.
