County Construction / Building Permit Fees

A Building Permit must be obtained from the county government before commencing any construction, renovation, or extension of a structure. It is governed by the Physical Planning Act (Cap. 286), the Local Government Act, and the National Construction Authority (NCA) Act. The permit ensures that planned construction meets safety standards, zoning regulations, and approved architectural plans. Issuing Authority: County Government Physical Planning Department / Urban Planning Department
