If you are building in Kenya, the same names come up again and again: the County Government, the NCA, NEMA and, for some projects, EPRA and KCAA. Put simply, the County approves your building, the NCA vouches for your contractor, NEMA protects the environment, and EPRA and KCAA step in when a project involves energy or height. Getting the right NCA and NEMA approval, alongside County permits, is what makes a build legal.
For many investors these acronyms are confusing, and that confusion is exactly what rogue contractors exploit when they say "everything is handled" while quietly building without permits. This guide explains each approval, why it exists and what your building actually needs, so you know what you are paying for and which documents to ask to see.
1. County Government approvals
What it is: approval from your County Government is your permission to build. It confirms that your plans follow the building code, zoning and planning rules for that area.
What it covers:
Architectural plans: the design, layout and use of the building.
Structural plans: the engineering that keeps the building safe and standing.
Change of user and zoning: confirmation that the land can legally be used for what you plan to build.
The construction permit: the formal go-ahead to start work.
Inspections and occupation: inspections at key stages, then an occupation certificate when the building is complete.
Why it matters: without County approval, your building is illegal from day one. The county can issue a stop order, fine you or order demolition at any point.
What your building needs: approved architectural and structural drawings and a valid construction permit before any work begins, followed by inspections at the stages your county requires. For the risks of skipping this step, read why some developers skip building approvals.
2. NCA approval: the National Construction Authority
What it is: the National Construction Authority regulates the construction industry and the people who work in it. The County approves the building; the NCA registers the contractor and oversees standards and safety on site.
What it covers:
Contractor registration: every contractor must be registered with the NCA and hold a current licence.
Contractor categories: contractors are graded by capacity, from NCA1 (the highest, for the largest projects) down to NCA8 (entry level, for smaller works). Your contractor must hold the right category for the size and type of your project.
Project registration: construction projects are registered with the NCA before work begins.
Site safety and standards: the NCA promotes safety and quality on site and can inspect works.
Worker accreditation: skilled construction workers and site supervisors are accredited by the NCA.
Why it matters: an unregistered contractor is unaccountable. If they are not on the NCA register, no authority has checked that they are competent or legally allowed to build. That is a serious red flag.
What your building needs: a contractor with an active NCA licence in the correct category, and the project itself registered with the NCA. You can check this yourself from anywhere in the world using the NCA's online "Search Registered Contractors" and "Verify Certificate" tools. Our step-by-step guide shows how to verify an NCA registered contractor.
3. NEMA approval: the National Environment Management Authority
What it is: the National Environment Management Authority safeguards the environment and makes sure developments do not cause avoidable harm.
What it covers:
Environmental Impact Assessment (EIA): a study of how the project will affect its surroundings, required for larger or higher-impact developments before construction starts.
EIA licence: issued by NEMA once the assessment is satisfactory.
Environmental compliance: making sure drainage, waste and effluent are properly managed during and after construction.
Why it matters: where an EIA is required, building without NEMA approval is illegal and can lead to penalties or a halt to works. It also protects you from finishing a building that later faces environmental objections.
What your building needs: NEMA approval wherever it is required. Not every small home triggers a full EIA, but many developments do. A qualified professional will tell you whether yours does and handle it properly. Never assume it does not apply without checking.
4. Specialised approvals: EPRA and KCAA
Not every building needs these, but certain projects do, and leaving them out is just as serious as skipping the main three. Pay close attention if your development involves energy, fuel or significant height.
EPRA: Energy and Petroleum Regulatory Authority
What it is: the Energy and Petroleum Regulatory Authority regulates Kenya's energy and petroleum sectors. If your project involves energy infrastructure or fuel, EPRA approval is required.
When your building needs it:
Petrol stations and fuel storage: building and operating them requires EPRA licensing and strict safety standards.
LPG storage and filling installations.
Solar PV installations: solar technicians and contractors must be EPRA licensed, and larger systems need approval.
Electrical installation work: electricians and electrical contractors must be EPRA licensed, and significant installations need inspection.
Power generation and distribution projects.
Why it matters: energy and fuel installations carry serious fire, explosion and electrical risks. EPRA approval confirms the work is designed, installed and operated safely and legally.
KCAA: Kenya Civil Aviation Authority
What it is: the Kenya Civil Aviation Authority regulates airspace and aviation safety. Tall structures can obstruct flight paths, so some buildings need aviation clearance.
When your building needs it:
Tall buildings and high-rise developments, especially near airports, airstrips or flight paths.
Telecommunication masts, towers and antennas.
Any structure above the height limits set for controlled or sensitive zones.
Why it matters: KCAA height clearance confirms your structure will not endanger aircraft. Without it, a tall building can be refused approval, forced to reduce its height or face legal action, sometimes after it has already been built.
What your building needs: EPRA approval for energy, fuel, solar or significant electrical work, and KCAA clearance for tall or aviation-sensitive structures, but only if your project triggers them. A competent professional will identify this early and manage the process.
How NCA, NEMA and County approvals work together
Think of these approvals as a chain of accountability, with each one checking something different. The first three apply to almost every project; EPRA and KCAA apply only when your project involves energy, fuel or significant height.
Approval | Regulates | Confirms | Key document |
|---|---|---|---|
County Government | The building | Plans are safe, legal and correctly zoned | Approved plans and construction permit |
NCA | The contractor and the industry | The builder is qualified, licensed and accountable | NCA contractor licence and project registration |
NEMA | The environment | No avoidable environmental harm | EIA licence (where required) |
EPRA | Energy and petroleum works | Energy, fuel, electrical and solar work is safe and legal | EPRA licence or approval (where required) |
KCAA | Airspace and aviation safety | Tall or aviation-sensitive structures are cleared | KCAA height clearance (where required) |
Each approval covers a gap the others do not. Skip one that applies to your project and part of your build goes unchecked, which is where safety failures, legal trouble and financial loss begin.
What diaspora investors should insist on
From abroad you cannot inspect the site yourself, so insist on seeing the paperwork and checking it independently:
Copies of every approval: approved plans, the construction permit, the NCA registration and the NEMA licence where required.
Specialised approvals where they apply: EPRA licensing for energy, fuel, solar or significant electrical work, and KCAA clearance for tall or aviation-sensitive structures.
Your contractor's NCA status, checked online, and for electrical or solar work, proof that the installer is EPRA licensed.
The right NCA category for the size of your project.
Professional oversight on the ground to confirm the approvals are genuine and the build follows the approved plans. Our construction management service does exactly this.
Payments tied to verified progress: milestone payments and escrow protection keep your money safe until the paperwork and the work have been checked.
A contractor who is reluctant to show you these documents is telling you something important. Listen. For more on staying in control from a distance, see how to manage construction in Kenya from abroad and our checklist before building a house in Kenya.
Questions people ask
Do I need NEMA approval to build a house in Kenya?
Not always. Many small, single homes do not need a full Environmental Impact Assessment, but larger developments, apartments and projects in sensitive areas usually do. Ask a qualified professional to confirm before you start.
What is the difference between NCA and County approval?
County approval is about the building: its plans, zoning and permit. NCA approval is about the builder: their registration, category and accountability, plus registration of the project itself. You need both.
Can I check approvals myself from abroad?
Yes, partly. You can verify a contractor's NCA registration online in minutes. For County and NEMA documents, ask for copies and have an independent professional confirm they are genuine.
Who applies for these approvals, me or the contractor?
Usually your architect, engineer or project manager prepares and submits the applications on your behalf. Whoever handles it, the approvals belong to your project, so make sure you receive copies.
