So you’ve got the land, the savings, and the plan in your head — but before a single block goes up, there’s one thing that trips up more Kenyan builders than budget ever does: approvals.
Every year we meet clients at Jowach Construction who assumed a permit was “just paperwork,” only to find their site red-flagged mid-build because a structural drawing was never stamped, or an NCA registration lapsed. The rules aren’t complicated once you know the order they come in — this guide walks you through exactly that.
Why You Can’t Skip Building Approval in Kenya
Any structure with a foundation — a bungalow, a maisonette, a rental block, a perimeter wall — legally needs county approval before construction starts. This isn’t a bureaucratic formality. County governments, working through their physical planning departments, use it to confirm your design won’t collapse, won’t block a neighbour’s access, and meets the National Building Code.
Build without it, and you’re not just risking a fine. County inspectors and the National Construction Authority (NCA) can issue a stop-work order or, in serious cases, a demolition notice — even after you’ve already spent money on materials and labour.
The 6 Stages of Building Approval in Kenya
Stage 1: Engage Registered Professionals
Before you submit anything, you need:
- An architect registered with the Board of Registration of Architects and Quantity Surveyors (BORAQs)
- A structural engineer registered with the Engineers Board of Kenya (EBK)
- A contractor registered with the National Construction Authority (NCA), with a current, renewed licence
Skipping registered professionals is the single biggest reason approvals get rejected or delayed.
Stage 2: Architectural Plan Submission
Your architect submits your drawings — most counties now use an online e-Development Permit System (eDAMS), including Nairobi, Kiambu, and Mombasa. Once the architectural plans are approved online, hard copies still need to be physically stamped at the county offices.
Stage 3: Structural Plan Approval
Only after architectural approval can your structural engineer submit the structural drawings. This stage checks that the building can actually stand — foundation design, beam sizing, load calculations — and is especially strict on tricky sites like black cotton soil.
Stage 4: NEMA Approval (Where Required)
Commercial projects, and some larger residential developments, need clearance from the National Environment Management Authority (NEMA). A NEMA-licensed expert carries out an Environmental Impact Assessment (EIA), which is submitted alongside your approved county drawings.
Stage 5: NCA Project Registration
With county-approved drawings in hand, your contractor registers the project with the NCA:
| Project Value | NCA Fee |
|---|---|
| Below KSh 5 million | Free registration |
| Above KSh 5 million | 0.5% of contract value |
NCA typically takes a minimum of 7 working days to evaluate the application. Once approved, you’ll receive a project registration certificate — keep it displayed on-site for the whole build.
Stage 6: Commencement Notice and Ground-Breaking
Once you have county approval, NEMA clearance (if applicable), and NCA registration, you can legally break ground. Most counties require you to start construction within 6–12 months of approval, or the permit lapses — so don’t sit on a stamped plan for too long.
Documents You’ll Need at Submission
- Architectural drawings (BORAQs-registered architect)
- Structural drawings (EBK-registered engineer)
- Title deed or land ownership documents
- Land rates clearance certificate
- Survey map / beacon certificate
- Bill of quantities
- Contract agreement between client and contractor
How Much Do Building Approvals Cost in Kenya?
Fees vary significantly by county and are usually calculated as a percentage of your construction value rather than a flat rate. As a rough guide:
- Development permission fees: typically a fraction of a percent of construction value
- Building permit fees: similarly value-based, higher in counties like Nairobi than in smaller municipalities
- NCA registration: free under KSh 5 million, 0.5% of contract value above that
Always request an official receipt for every payment, and confirm current rates directly with your county’s physical planning department — they do change.
Common Mistakes That Delay Approval
- Submitting structural drawings before architectural plans are approved
- Using a contractor whose NCA licence has lapsed
- Skipping the pre-application consultation with the county planning office
- Assuming one county’s process applies everywhere — Nairobi, Kiambu, and smaller counties all handle submissions differently
- Starting construction before the commencement notice is issued

Frequently Asked Questions
How long does building approval take in Kenya? County architectural approval can take anywhere from a few weeks to a couple of months depending on the county and how complete your submission is. NCA registration adds a minimum of about 7 working days on top of that.
Do I need NEMA approval for a residential house? Most standalone residential homes don’t require a full NEMA EIA, but larger developments, rental blocks, and commercial projects usually do. Check with your county planning office to confirm for your specific project.
What happens if I build without approval in Kenya? You risk fines, a stop-work order, or in serious cases a demolition notice from the county or NCA — even if construction is already underway.
Can I start construction while my permit is still processing? In some counties, once your drawings are approved (even before the final building permit is issued), you may begin groundwork. This varies by county, so confirm locally before starting.
Does a building permit expire? Yes. Most counties require construction to begin within 6–12 months of approval, and the total approved construction period is usually capped at 2–3 years.
