How much does it cost to build a 20 unit apartment complex in Kenya? If you are planning to build apartments in 2026, you likely need a simple answer. Based on current market rates, you should budget between KES 80 million and KES 140 million. This wide range depends on where you build, the type of finishes you choose, and how you manage the project .
Building an apartment is a big step for you. It can give you good money every month from rent. But if you do not plan the costs well, you might lose money. This guide will walk you through every cost in simple terms. We will look at the cost per square meter, permit fees, material prices, and even labor. By the end, you will know exactly where your money goes.
We have used the latest 2025 and 2026 data from Kenyan construction experts. Let us break it down so you can build smart.
What You Will Pay Per Square Meter in 2026
First, you need to understand the cost per square meter. This is the standard way to measure building costs in Kenya. In 2026, building a standard apartment block will cost you between KES 55,000 and KES 75,000 per square meter .
However, the Architectural Association of Kenya (AAK) notes that prices have gone up. In 2025, standard low-rise apartments cost about KES 68,837 per square meter. That was a rise of almost 14% from the year before . So, for 2026, you must budget for these higher prices.
For your 20-unit block, the total square meters will be around 1,500 m² to 2,000 m². Here is a simple table showing your possible total build cost:
| Building Quality | Cost Per m² | Total Cost (for 1,800 m²) |
|---|---|---|
| Basic / Low-Cost | KES 50,000 | KES 90 Million |
| Standard / Mid-Range | KES 65,000 | KES 117 Million |
| High-End Finishes | KES 80,000+ | KES 144 Million+ |

Breakdown of What You Will Spend to Build 20 Units
To understand how much does it cost to build a 20 unit apartment complex in Kenya, you cannot just look at the main contractor. You have to look at the small pieces. Here is a simple breakdown of where your money goes.
1. Materials (45% – 55% of Your Budget)
Materials are your biggest cost. This includes cement, steel, ballast, sand, roofing, tiles, and paint. Prices change often. For example, in late 2025, steel prices went up by 5.2% .
- Cement: You will pay KES 700 – 800 per bag .
- Steel: You will pay KES 95,000 – 120,000 per tonne .
- Sand and Ballast: Prices vary by location, but transport adds to your cost.
2. Labor (25% – 30% of Your Budget)
You need to pay skilled workers. In cities like Nairobi, labor costs you more. In places like Eldoret or Kisumu, it can be slightly cheaper .
- Skilled fundis (masons, carpenters): You will pay KES 1,000 – 1,500 per day .
- Electricians and Plumbers: You are usually charged per point or per day, around KES 1,500 – 2,500 .
3. Professional Fees (6% – 8% of Your Budget)
You cannot build without experts. These fees cover the people who design and check your work.
- Architect: Designs your building and gets your plan approved.
- Structural Engineer: Makes sure your building is safe.
- Quantity Surveyor (QS): Helps you control costs and prevents wastage.
- Total Fees: For your KES 100M project, professional fees will cost you about KES 6M to KES 8M .
4. Statutory Approvals (KES 500k – KES 1.5M)
Before you lay one brick, you must pay the government. In Nairobi, for example, you need several licenses :
- Building Permit: Usually costs you about 0.5% of your construction cost .
- NEMA License: For environmental impact assessment, costing you between KES 50,000 and KES 200,000 .
- NCA Registration: For your contractor .
Example Budget for Your 20-Unit Block
Let us look at an example. Imagine you want to build 20 units. You decide to build 10 one-bedroom units (45m² each) and 10 two-bedroom units (65m² each). This is a common mix for rental income .
Step 1: Calculate Your Total Area
- One-bedroom total: 10 x 45m² = 450m²
- Two-bedroom total: 10 x 65m² = 650m²
- Your Unit Area Total: 1,100m²
- Add 20% for corridors, stairs, and passageways (common areas) = 220m²
- Your Total Built-Up Area: 1,320m²
Step 2: Calculate Your Base Cost
Using a standard cost of KES 65,000 per m²:
- 1,320 m² x KES 65,000 = KES 85,800,000
Step 3: Add All Your Other Costs
- Professional Fees (7%): KES 6,006,000
- Statutory Approvals: KES 800,000
- Site Preparation & Utilities: KES 500,000
- Contingency (10% for unexpected issues): KES 8,580,000
- Your Total Project Cost: KES 101,686,000
So, for this 20-unit complex, you need to budget roughly KES 102 Million .
How Your Location Changes Your Costs
Where you build changes what you pay. Transporting materials to remote places costs you more. Labor rates also change. Here is how costs compare for you:
- Nairobi: KES 60,000 – 90,000 per m². This is your most expensive option due to high land prices and demand .
- Mombasa: KES 55,000 – 80,000 per m². Building at the coast requires special materials to resist salt, which will cost you extra .
- Kisumu / Eldoret: KES 45,000 – 65,000 per m². Labor is cheaper for you here, and you may source materials locally .
- Rural Areas: KES 40,000 – 55,000 per m². Your costs are lower, but transporting materials might be tricky for you .
Hidden Costs You Must Plan For
Many first-time developers forget these costs. Do not let them surprise you.
1. Land and Legal Fees
The cost of your land is separate from construction. In Nairobi, a 1/8 acre plot can cost you KES 15M or more. You also need to pay for:
- Transfer of Title: About 4% of your land value in cities.
- Legal Fees: For your lawyer to handle the sale agreement.
2. Utility Connections
Getting power and water to your site costs you money.
- KPLC Connection: KES 70,000 – 150,000 .
- Water Connection: KES 30,000 – 80,000 .
- Borehole: If there is no piped water, a borehole can cost you KES 1.5M – 3M.
3. Your Cost of Money (Financing)
If you take a bank loan, the interest adds to your costs. Bank construction loans in Kenya have interest rates around 12% – 16% per year . If your project takes 18 months, the interest alone could cost you millions.
4. Inflation and Price Rises
Construction costs in Kenya rose by 16% in just 10 months in 2025 . When you budget, you must add money for inflation. This is why your contingency fund (10-15%) is so important .
How You Can Save Money on Your Apartment Project
You do not have to spend the maximum amount. Here are simple ways for you to save money:
- Use Local Materials: Instead of importing expensive tiles, buy good quality local tiles. Use quarry stones or stabilized soil blocks instead of just concrete blocks .
- Simplify Your Design: A box-shaped building with a simple roof costs you less to build than one with many corners and curves .
- Hire a Good Quantity Surveyor: They will stop you from wasting materials. They make sure you buy the right amount of cement and steel.
- Buy in Bulk: Buy materials like cement and steel for your whole project at once to get a discount .
- Phase Your Project: If you have limited cash, build in phases. Finish your first block, get tenants, then use that money to build your next phase .
Financing Options for You as a Developer
Raising KES 100 million is hard. Here is where you can get the money:
- Bank Construction Loans: The most common option for you. You need a good plan and the land title. Interest rates are high .
- SACCOs: Often have lower interest rates for you than banks. Good if you are a salaried member .
- Joint Ventures (JV): Partner with someone who has land or money. You share the profits. NSSF is doing this in Kisumu to build houses .
- Government Affordable Housing Program: If your units meet the “affordable” price point (under KES 3M – 4M), you might get government support or tax breaks .
Is Building a 20-Unit Apartment Worth It for You?
Yes, it can be. Demand for rental housing in Kenyan towns is high. Many families cannot afford to buy a house, so they rent .
If your 20 units each rent for KES 20,000 per month, your gross monthly income is KES 400,000. Per year, that is KES 4.8 Million. After you pay for caretakers, repairs, and taxes, you will make a profit. Over time, your building also increases in value.
Final Thoughts
So, how much does it cost to build a 20 unit apartment complex in Kenya? Your realistic budget for 2026 is between KES 80 Million and KES 140 Million. The exact number depends on your finishes, your location, and how well you control your costs.
Remember to include all your costs: materials, labor, professionals, permits, and a contingency fund for surprises. Building an apartment is a big task for you, but with careful planning and the right team, it can be a great investment for your future.
