- Treated pine sleeper wall: about $250 to $450 per square metre of face (Yakka Labour, indicative)

Common questions
Do I need a building approval for a retaining wall in Canberra?
ACT Planning says a retaining wall does not need a building approval if it is not higher than 1.2 metres from the top of the wall to the lowest adjacent ground level. A wall up to 1.5 metres may also be exempt if it complies with the exempt building code and the building code. Check the page for your wall.
Do I need a development approval as well?
Possibly. ACT Planning says you should self-check the development approval exemptions separately. It describes different height limits for cut-in walls, fill walls and parts of a wall within 1.5 metres of a side or rear boundary.
What is a cut-in wall and what is a fill wall?
ACT Planning describes a cut-in wall as one that keeps an embankment cut below datum ground level and a fill wall as one that keeps soil above it. A wall that does both is a combination wall.
How is the height measured?
ACT Planning measures from the top of the wall to the lowest adjacent ground level. An Access Canberra factsheet says the height in the building exemptions refers to the actual earth cut that has to be retained, not how the wall looks.

Start with the approval rules
Canberra's rules are set by the ACT Government and they are worth reading before you draw a line on the lawn. ACT Planning says a retaining wall does not need a building approval if it is not higher than 1.2 metres, measured from the top of the wall to the lowest adjacent ground level, and that a wall up to 1.5 metres can also be exempt if it meets the building code and is built in a proper and skilful way. A separate page covers development approval and uses different limits for cut-in walls, fill walls and walls near a boundary. Read both for your block.

Cut and fill are treated differently
The development approval page describes a cut-in wall as one that keeps an embankment cut below ground level, and a fill wall as one that keeps soil above ground level. It gives different height limits for each, and lower limits for any part within 1.5 metres of a side or rear boundary. Many Canberra blocks have a slope that needs both, which makes the wall a combination wall. If you are unsure which type yours is, ask a building certifier before you sign anything. ACT Planning says a building certifier can issue a formal exemption notice.

Who holds a licence in the ACT
ACT Planning says builders, plumbers, drainers, electricians and gasfitters need a licence under the Construction Occupations (Licensing) Act 2004, and that carpenters and bricklayers do not currently need one. It also says a builder must be local to complete work that requires building approval. Access Canberra keeps the public registers, including local builders and local drainers, and its page on choosing a tradesperson says to check that the person is appropriately local. A short search before you sign costs nothing.

Insurance and showing your licence
ACT Planning says a person who holds a construction occupations licence must show a client their insurance when they work for them, even if the client has not asked. That is a good reason to ask. Request a copy in writing, check the business's licence on the Access Canberra public register and keep both with the contract. If a business tells you no licence is needed for your job, ask which page of the ACT rules says so, and compare that with what the register and the planning pages say.

What a retaining wall costs
Yakka Labour gives $250 to $1,000 per square metre of wall face for installed walls in Australia, with treated pine at the low end and reinforced masonry, sandstone or poured concrete at the top. Its Canberra figure for a concrete sleeper wall under one metre high is $400 to $630 per square metre. Karven gives $250 to $450 for treated timber and $350 to $650 for concrete sleepers. They are national guides, not Canberra quotes. Our cost guide shows every row with its unit and the date we read it.

The costs behind the wall
Yakka Labour says the part you can see is only half the story. Excavation and spoil removal, a footing, slotted drainage pipe, clean gravel and an outlet are often where the money goes, and an engineer's design and any approval fees come on top. Karven makes the same point and says the most common corner cut on cheap quotes is the drainage. When two quotes differ by thousands, the cause is usually that one lists the groundwork and the other leaves it out.

Canberra weather and the ground
The Bureau of Meteorology's Canberra Airport statistics show a mean July maximum of 12.9 degrees and a lowest recorded temperature of minus 8.7. Yakka Labour says frost affects concrete timing in Canberra. Wikipedia says the Brindabellas lie south and west of the city and form the northern part of the Australian Alps. Ask each builder how cold mornings and wet clay behind a wall change their method.

Check for pipes and cables before you dig
Before You Dig Australia says it provides a single point of contact for information about underground or overhead infrastructure at a planned work site, and that you register online, submit your request and receive asset plans by email. Retaining walls mean digging for footings and drainage, so ask each builder who requests the plans and whether that is in the price. If you plan to dig a footing yourself, make the request yourself.

Choosing a wall type
Yakka Labour says treated pine is the cheapest and lasts 15 to 25 years, concrete sleepers with steel posts are the workhorse of suburban retaining, segmental blocks suit curves and taller walls with geogrid, and masonry or poured concrete suit structural walls. Natural stone looks good and lasts, but costs more. Each of our wall guides sets out the questions that matter for that material, and our suburb guides cover the places where we have something specific to cite.

Get written quotes
Compare at least two written quotes for the same wall, with the same height, the same drainage and the same list of what is excluded. Ask who is responsible for approvals and for Before You Dig, and what happens if the ground is worse than expected.
Do I need approval for a retaining wall in Canberra?
ACT Planning says a wall not higher than 1.2 metres, measured to the lowest adjacent ground, does not need a building approval, and it publishes separate development approval limits. Check both pages for your block or ask a building certifier.
Does a retaining wall builder need a licence in the ACT?
ACT Planning says builders need a licence for work that requires building approval, while carpenters and bricklayers do not currently need one. Check the Access Canberra register and ask each business what applies to your job.
How much does a retaining wall cost per square metre?
Yakka Labour gives $250 to $1,000 per square metre of face nationally, and $400 to $630 for a concrete sleeper wall in Canberra. They are guides, not quotes.
Is an engineer needed?
ACT Planning says design and construction standards apply to a wall higher than 1.2 metres. Yakka Labour says an engineer's design usually costs $800 to $3,000. Ask a certifier or the builder whether yours needs one.
Who checks for underground pipes and cables?
Before You Dig Australia gives asset plans on request. Ask each builder who requests them and make sure it is clear in the quote.
