CONSTRUCTION OF BUILDINGS IN UGANDA: WHAT YOU NEED TO KNOW
Construction of buildings in Uganda is an aspect that is regulated by various laws. Thus for one to erect a building, be it commercial or residential, he/she has to be cautious of various requirements and conditions imposed by different laws. The laws among others include the Building Control Act, 2013, the Physical Planning Act, 2010, The National Environment Act, 2019, the Land Act and the Occupational Safety & Health Act. There are also Regulations and Codes made under the Building Control Act. These are; the Building Control Regulations, 2020, the National Building (Building Standards Code) 2019, the Building Control (Accessibility Standards for Persons with Disabilities) Code, 2019, The Building Control Regulations, 2020, The National Building (Standards for Electrical Installations in Buildings) Code, 2019
Article 39 of the 1995 Constitution accords to every Ugandan a right to a clean and healthy environment. The National Environmental Act under Section 3 provides that every person has a right to a clean and healthy environment in accordance with the Constitution and the principles of sustainable development. It is the duty of every person to create, maintain and enhance the environment. Where the right to a clean and descent environment is threatened by an act or omission of any person which has or is likely to cause harm to human health, the law allows any person to file a civil suit by way of Public Interest Litigation against such a person since exercising proprietary rights should not negatively affect the public. See Nyakana-v- National Environmental Authority Constitutional Appeal No. 5 of 2015.
The law requires every developer of a project or any activity that is likely to have significant adverse impacts on human health or the environment to cause to be conducted environmental and Social Impact Assessment for the purpose of evaluating environmental and social impacts, risks or other concerns of a given project or activity taking into account the environmental principles. In this article, my emphasis is on the law relating to erection of buildings and building standards.
Physical Planning Act, 2010
The Physical Planning Act, which applies to the entire country in all respects declared the entire country a planning area. The law prohibits any person from carrying out a development without obtaining development permission from the respective Physical Planning Committee.
The Building Control Act, 2013
The Building Control Act takes precedence over other Acts or instrument in existence, relating to building operations and all Acts or instruments must comply with this Act. Where a provision of any law conflicts with a provision of this Act, the Building Control Act shall prevail. The purpose of this Act is to consolidate, harmonize and amend the law relating to the erection of buildings, provide for building standards, establish a National Building Review Board, Building Committees, promote and ensure planned, decent and safe building structures that are developed in harmony with the environment and for other related matters.
Establishment and Functions of the National Building Review Board
The Building Control Act establishes a National Building Review Board. The Board consists of the representatives from the following departments; building works, physical planning, housing, the Ministry responsible for water and environment, the Ministry responsible for persons with disabilities and a representative of each of the following professions nominated for appointment by the relevant professional body or association; engineers, architects, physical planners, surveyors, lawyers, a public health officer from the Ministry responsible for health, representative of persons with disabilities, representative of workers, representative of Uganda Local Authorities Association of Uganda, a representative of Urban Authorities Association of Uganda and one person from the private sector.
The functions of the Board are; to monitor building developments, ensure that the design and construction of buildings and utilities to which the public is to have access cater for persons with disabilities, to oversee, inspect and monitor the operations of Building Committees, to hear and determine appeals from persons dissatisfied with the decisions of the Building Committee, to determine the fees to be charged by urban and district building committees for approval of plans, issue of building permits and occupation permits.
Building Committees and Building Control Officer
The Act establishes for each District and Urban Authority, a Building Committee as a Committee of the District or the Urban Council respectively. In the case of a District Council, the Building Committee consists of the Chief Administrative Officer, Town Clerk, Chairperson of the Planning and Development Committee of the District Council, Officers responsible for physical planning, health, engineering, land management, environment management, architecture, a representative of the persons with disabilities, an officer from the police department responsible for fire prevention and a member of the district executive committee. In the case of an urban Authority, the Building Committee consists of the Chairperson of the Urban Planning and Development Committee, a category of Officers in the Urban Service similar to the category of officers in the District Council referred to above and a representative of the persons with disabilities.
According to section 29 of the Building Control Act, the functions of Building Committees are; to scrutinize and approve building plans, issue building and occupation permits, ensure that the design and construction of buildings and utilities to which the public is to have access cater for persons with disabilities, review decisions on applications for permits for minor building works submitted to a building control officer, ensure that this Act is complied with and to perform any other function assigned to it by the Board.
The Building Control Act under Section 32 requires the District Service Commission to appoint for each District Council and Urban Authority, a District Building Control Officer and an Urban Building Control Officer, respectively and such number of Assistant Building Control Officers necessary to enable the Building Committee effectively carry out its functions. The law prescribes qualifications for a building control officer and urban Building Control Officer.
The functions of a Building Control Officer among others include; making recommendations to a Building Committee in relation to, building plans, specifications of materials and workmanship, to forward to the Building Committee for review, copies of all applications for minor building works submitted to the Building Control Officer, and his or her decision on the application, to ensure that any instructions given by a Building Committee in accordance with the law are complied with, to inspect the erection of any building, the demolition of any building, any activity, in respect of which a permit has been issued, ensure that any condition upon which the permit is issued is complied with, to carry out regular inspection of completed buildings and to carry out any other duty assigned to it by the Building Committee.
Building operations without permit prohibited
The Building Control Act under section 34 the law prohibits any person from carrying out a building operation unless he or she has a valid building permit issued by a Building Committee. It is thus offence punishable with imprisonment or fine or both to carry out a building operation without a building permit.
Application and Issuance of building permit
Any person who intends to carry out a building operation must apply for a building permit to the Building Committee of the area he or she intends to carry out the building operation.

Classification of Building Developments
Building Control Regulations classifies building developments according to form, size, complexity, social and environmental impact under three categories; A, B and C. Category A comprises of Complex structural forms, public buildings, multi storeyed buildings of more than 12m high, building complexes (mixture of all) such as schools, hospitals, shopping malls, buildings of high social impact or to be located in sensitive ecosystem among others. Category B comprises Residential or commercial buildings, floor area >30m2, single or multi-storeyed of up to 12m high of simple structural form, boundary wall built of bricks, concrete or other solid material of permanent nature. Category C comprises of Minor and temporary buildings; Floor area <30m2; single storey; of simple structural form.
The law prescribes minimum standard and requirements for civil or structural plans, electrical engineering installation plans and mechanical engineering installation plans. For instance, Regulation 9 requires architectural plans were applicable to consist to the satisfaction of the Building Committee, location plan, context or block plan, site plan, floor plans, elevations, sections, door and window schedules drainage plans, storm, foul and waste water and boundary wall plan and details. Civil or structural engineering plans, drawings and diagrams should contain, where applicable; excavation details, foundation details, column details, beam details, beam-column connections, slab details, staircases, lift wells roof details and retaining structure details.
The Electrical engineering installation plans, drawings and diagrams where applicable should contain mains and standby power supply, power reticulation, lighting layout, small power layout, fire protection, private automatic branch exchange system, local area data network and closed circuit television. Mechanical engineering installation plans, drawings and diagrams must contain water supply, water reticulation, water storage, ventilation and air conditioning, drainage and firefighting.
