Licensing in brief. South Australia's licensing of building work contractors, the supervisor registration behind it and what advertising has to show are covered on our page for Adelaide builders. For landscapers, two points stand out. The Legal Services Commission's Law Handbook notes that domestic building work includes types of work prescribed by regulation, such as paving and fencing as well as swimming pools, and CBS has publicly warned that paving, retaining walls and shade sails need a licence. Since 10 November 2025, domestic building work worth less than twenty thousand dollars is classed as minor domestic building work, which isn't regulated to the same level as larger contracts.
Retaining walls and the neighbours. According to the Law Handbook's retaining walls page, a wall built for landscaping that retains a difference in ground level of one metre or less doesn't usually need development approval, although some zones and council areas differ. Tiered walls are measured together by the overall change in level, and a fence on top brings approval into play once wall and fence pass 2.1 metres from the low side. Separately, fill within 600 millimetres of a boundary (unless it's landscaping fill of 200 millimetres or less) and excavation that cuts below a line set by the regulations near a boundary are treated as affecting the stability of the neighbour's land. That can bring a duty to serve the neighbour a Form 1 notice at least 20 working days before work starts. A landscaper who handles that paperwork, or works with an engineer who does, has something concrete to say on a retaining walls page.
Trees. The Planning and Design Code's Regulated and Significant Tree Overlay covers metropolitan Adelaide, townships in the Adelaide Hills Council and parts of the Mount Barker Council. Since 16 May 2024 a single-trunk tree is regulated at a circumference of one metre and significant at two metres, both measured a metre above natural ground, and any tree-damaging activity, which takes in substantial damage to the roots, needs development approval. The City of Burnside's trees and development FAQs list cut and fill and sealing with impermeable surfaces among the activities not allowed inside a tree protection zone. Exemptions include trees within three metres of a house or in-ground pool on the same block (not Eucalyptus, Corymbia, Angophora or Willow Myrtle) and trees within 20 metres of a house in a medium or high bushfire risk area. A paving or wall job under a large tree is where this comes up.
Gardens on new infill homes. Since the Planning and Design Code began in March 2021, new homes in metropolitan Adelaide have had to include soft landscaping and, where the Urban Tree Canopy Overlay applies, at least one tree. The City of West Torrens' 2021 summary of the Code sets the soft landscaping at a minimum width of 700 millimetres over 10 per cent of a site under 150 square metres, rising in steps to 25 per cent of a site over 450, plus at least 30 per cent of the land between the street boundary and the front of the house. Larger blocks call for more or bigger trees, and a payment into the state's Urban Tree Canopy Off-set Fund can stand in for planting. PlanSA lists a Tree Protection and Planting Code Amendment, so check the current Code before your site quotes any figure. In 2022 Green Adelaide and the State Planning Commission published the Adelaide Garden Guide for New Homes, with small garden designs that fit those rules. If you plant to them, say so, and show the plan next to the finished garden; the wording comes from you, and we don't claim compliance on your behalf.
Where Adelaide landscapers get seen, and how we work. Master Landscapers South Australia, the industry body for landscaping in Adelaide and regional SA, runs the Awards of Excellence, with award galleries on its site for each year from 2022, and keeps a Find a Professional directory for landscapers, garden maintenance, landscape designers and suppliers. With Open Gardens SA it runs the SA Landscape Festival, first held in April 2021, when professionally designed private gardens open to visitors; the 2025 festival included gardens at Belair, Blackwood, Aldinga Beach and Torrens Park. We're at Ste 3/110 Hutt St in the city. Most projects run by phone and email, which suits people who spend the day on site, and if you'd rather meet before we start, that can be arranged.
