Three environmental regimes can stop a construction project before it starts: environmental authorisation under NEMA for listed activities, a water use licence for work in or near watercourses, and waste rules under NEMWA. On top of that sits the most-missed rule in SA renovation: under section 34 of the National Heritage Resources Act, no structure older than 60 years may be altered or demolished without a permit from the Provincial Heritage Resources Authority, listed or not. Check all four before pricing, because the penalties run to imprisonment.
NEMA: when you need environmental authorisation
Environmental assessment is anchored in Chapter 5 of the National Environmental Management Act 107 of 1998 (NEMA), implemented through the EIA Regulations 2014 (as amended) and three Listing Notices (GNR 983, 984 and 985). Two assessment types exist:
- Basic Assessment: for activities in Listing Notices 1 and 3, the smaller-scale impacts.
- Scoping and EIA: for Listing Notice 2 activities, the larger or potentially significant impacts.
Common construction triggers include linear developments (roads, walls, pipelines, power lines) longer than 300 m, development within 32 m of a watercourse or 500 m of a wetland, earthworks above prescribed thresholds, and ground-mounted solar above 1 MW on sensitive land. Before starting, check all three Listing Notices. A registered Environmental Assessment Practitioner must run the process, and the decision sits with the Department of Forestry, Fisheries and the Environment or the provincial environmental department.
Water use licensing
The National Water Act 36 of 1998 requires a Water Use Licence from the Department of Water and Sanitation for, among other things: abstracting or storing water, impeding or diverting a watercourse (triggered by any development that changes water flow), altering the bed, banks or characteristics of a watercourse, and disposing of waste or wastewater that affects a water resource. Smaller uses below defined thresholds can fall under a General Authorisation instead of a full licence; the thresholds change, so confirm the current General Authorisation limits with the DWS before assuming you are under them.
Construction waste under NEMWA
Construction and demolition waste is regulated under the National Environmental Management: Waste Act 59 of 2008. A waste management licence is needed for storage of general waste above 100 m3 (with a Basic Assessment) or building waste disposal facilities above 50 tonnes per day (with Scoping and EIA). For a typical small project the rules are simpler but real: separate waste streams, handle hazardous waste (asbestos, chemical containers) under its own regulations, and send general construction waste to a licensed landfill, with the disposal slips kept in the job file. See the asbestos rules guide for the hazardous end of this.
The 60-year heritage rule
Section 34 of the National Heritage Resources Act 25 of 1999 (NHRA): no person may alter or demolish any structure, or part of one, older than 60 years without a permit from the Provincial Heritage Resources Authority (PHRA). "Alter" is defined broadly and includes painting, plastering, structural work and anything affecting the structure's appearance or physical properties. SAHRA handles nationally significant sites; the PHRA handles the rest.
The process: apply to the PHRA with a description of the proposed works. The PHRA must respond within 14 days to say whether a Heritage Impact Assessment is required. If it is, a heritage specialist prepares it, with public consultation. The permit, once granted, is valid for 2 years and is not transferable to a new owner. Section 38 of the NHRA separately triggers heritage assessment for larger developments: linear projects over 300 m, bridges over 50 m, rezonings and character-changing developments.
Penalties under section 51 are serious: fines without a cap and imprisonment from 3 months to 5 years, with up to 10 years for ongoing offences. And the rule is widely misunderstood: a pre-1966 house with no heritage listing at all still needs a PHRA permit for alterations. The 60-year line moves forward every year.
Worked example: the old farmhouse
A contractor is hired to gut-renovate a farmhouse built in 1955, now 71 years old. Before touching a wall: confirm whether the property is formally proclaimed (which adds restrictions), tell the client a PHRA permit is required for any alteration, and hold off until the permit is in hand. The client applies with a description of the works; if the PHRA considers the farmhouse significant, it may require a Heritage Impact Assessment first. Starting without the permit is a criminal offence, for the contractor as well as the owner.
Common mistakes
- Assuming heritage means "listed buildings". The 60-year rule applies to unlisted structures too.
- Diverting a stream "temporarily" for access. Impeding a watercourse is a licensed water use.
- Skipping the Listing Notice check on linear work. A 350 m boundary wall can be a listed activity.
- Dumping builder's rubble. Licensed landfill only, slips kept; illegal dumping carries municipal fines on top of NEMWA.
- Pricing demolition of an old structure without the permit timeline. The PHRA process, and a possible Heritage Impact Assessment, belongs in the programme.
