Container office rental in South Africa: sizes, 2026 prices and what to prepare on site
Headcore
In short
For container office rental in South Africa, one Gauteng hire company's 2026 list charges R1,600 a month for a 6 m site office, and one Western Cape list R2,600 to R2,700 per container for an unstated period, both before VAT. Crane-truck delivery and collection are extra. Plan a firm, level base and power, and agree who holds the electrical CoC.
What sizes of container office can you hire?
In South Africa, container site offices for hire come mainly in 3 m and 6 m lengths (10 and 20 ft); hire containers also come in 12 m (40 ft), and all are about 2.44 m wide. Most sizes and all weights below are from one Western Cape hire company's 2026 price list.[6][8][10]
| Length | Size (length x width x height) | Weight, storage unit | Offered for hire as |
|---|---|---|---|
| 3 m (10 ft) | 3 m x 2.44 m x 2.6 m | 1.8 t | Site office, with or without aircon; storage |
| 6 m (20 ft) | 6 m x 2.44 m x 2.6 m outside; about 5.89 m x 2.34 m x 2.39 m inside | 2.22 t | Site office (uninsulated, insulated with aircon, or insulated split office), office combination, conference pod, storage |
| 12 m (40 ft) | 12 m x 2.44 m x 2.6 m, or 2.9 m high | 3.68 t, or 3.86 t for the taller unit | Storage; one converter also builds offices at this length |
How much does container office rental cost?
In South Africa, one Gauteng hire company's 2026 list puts a standard 6 m site office at R1,600 a month, and one Western Cape list at R2,600 to R2,700 per container for a period it does not state, both before VAT, with delivery and collection usually quoted on top.[6][7][12]
In its prices valid from March 2026 to February 2027, one Western Cape hire company lists a 6 m site office at R2,600 plus VAT per container, or R2,700 with aircon, and a 3 m site office at R2,200, or R2,300 with aircon, with a minimum rental period of one month; the list does not say what period these prices cover.[6]
One Gauteng hire company's 2026 rental price list puts its standard 6 m site office at R1,600 a month excluding VAT: a used container with two aluminium windows with burglar bars, a steel door, a distribution board, four double plugs and two LED lights, with delivery quoted by address and offered in Gauteng only.[7]
In practice, the rent moves with the fit-out and the term, and transport is a separate line: another Gauteng supplier hires month to month, discounts fixed terms of 12 months or longer, and quotes delivery and collection separately by site location.[12][6][7]
What does a standard site office container include?
A standard hire site office is a steel container with a lockable door, windows with burglar bars, lights, plug points and a distribution board; insulation and aircon are the usual upgrade.[10][7][8]
One converter's basic office has 2 to 4 LED lights and 2 to 4 plug points, 2 to 4 steel windows with burglar bars and blinds, 1 to 2 steel doors with a 3-lever lock and acrylic paint flooring; its executive office adds 40 mm EPS panel insulation with internal wall cladding, a 12,000 BTU aircon with isolator and rubberised flooring.[10]
One hire company's insulated 6 m office has a distribution board "with main breaker, earth leakage, and secondary trips", a supply connection that "runs through the floor into a connector box", two 15 A single-phase double plugs, a 12,000 BTU heating and cooling aircon and a roof painted white to reflect sunlight. The company says the unit "comes with a wiring certificate".[9]
Who must hold an electrical CoC for a hired container office?
In South Africa, the Electrical Installation Regulations require every user or lessor of an electrical installation to "have a valid certificate of compliance for that installation", with a test report (regulation 7(1)). Regulation 1 defines an electrical installation as machinery on any premises used to carry electricity "from a point of control to a point of consumption".[2]
The user or lessor is responsible for the safety, safe use and maintenance of the installation, and a written undertaking can transfer that responsibility to the lessee "as if he or she were the user or lessor" (regulation 2(1) and (3)), so a container hire agreement should say who holds the certificate of compliance (CoC).[2]
Only a registered person may issue a CoC; for an installation fed by a single-phase supply at the point of control, that includes an electrical tester for single phase (definitions restated in GN 258 of 2012).[3]
On a construction site, regulation 24 of the Construction Regulations, 2014 also makes the contractor put all temporary electrical installations under the control of a competent person appointed in writing, and have them inspected "at least once a week", with the findings recorded in a register kept on site (regulation 24(c) and (d)).[1]
Do you need municipal approval for a container site office?
In South Africa, the National Building Regulations and Building Standards Act counts "any other structure, whether of a temporary or permanent nature" used for the accommodation or convenience of people or for storing goods as a building (section 1), and section 4(1) bars erecting a building without the local authority's prior written approval where plans must be submitted.[4]
In the consolidated text of the National Building Regulations that Overstrand Municipality publishes, regulation F10 lets an owner or a person doing building or demolition work erect "such temporary builder's sheds as may be necessary" on the site of that work, with their construction and location "to the satisfaction of the local authority" (F10(1) and (2)).[5]
In that text, builder's sheds may be used only for purposes connected with that work, security staff may be housed in them subject to conditions that protect health and avoid nuisance to neighbours, and the owner must remove them when the work ends or they are no longer needed (F10(3), (5) and (6)).[5]
In the same consolidated text, an owner who declares a building temporary can apply for provisional authorisation for a limited period; the local authority may ask for the period needed, a site plan, layout drawings and structural detail, and if plans for full approval are not submitted by the end of that period, or are refused, the owner must remove the building (regulation A23(1), (2), (3), (5) and (7)).[5]
What facilities must a construction site provide?
In South Africa, Construction Regulation 30(1) makes the contractor provide clean, hygienic and maintained facilities "at or within reasonable access of every construction site", in addition to the Facilities Regulations, 2004; the minimums below decide how many ablution and change-room units a site needs.[1]
| What | Minimum | Where the rule sits |
|---|---|---|
| Sanitary facilities | At least one for each sex and for every 30 workers | CR 30(1)(b) |
| Showers | After consultation with the employees or their representatives, or at least one for every 15 persons | CR 30(1)(a) |
| Changing facilities | For each sex | CR 30(1)(c) |
| Eating area | Sheltered | CR 30(1)(d) |
| Living accommodation | Reasonable and suitable, for workers far from home without adequate transport or other suitable accommodation | CR 30(2) |
| Health and safety file | Opened and kept on site by the principal contractor and by each contractor, and shown on request to an inspector or the client | CR 7(1)(b) and 7(2)(b) |

How do you prepare a site for a container office?
In practice, a container office needs a firm, level base, clear access for the crane truck that offloads it, and a power supply to connect to.[12][9]
One Gauteng supplier asks for "a firm, level surface and clear access for a 12m crane truck, with no overhead power lines or trees over the placement area"; on a construction site, Construction Regulation 24(a) separately requires the contractor to find and guard against danger from any electrical cable or apparatus under, over or on the site.[12][1]
On one hire company's office the supply connection runs through the floor into a connector box, so decide before delivery who runs the cable from your own board to that box. Another hire company asks that, where the client leases the property, the landlord signs an acknowledgement of the container lease.[9][7]
What to put in your request
- Number of units, with the length and use of each (for example two 6 m site offices and one 3 m office), and whether each needs insulation and aircon.[6][10]
- Fit-out per office: number of plug points and lights, a distribution board with earth leakage, windows with burglar bars, door and lock type, flooring and any partition.[10][9]
- Hire period: delivery date, expected number of months, and month to month or a fixed term of 12 months or more.[12][6]
- Separate prices for monthly rent, delivery and collection, each shown with and without VAT.[12][7]
- Site: street address, access route for a 12 m crane truck, any overhead power lines or trees over the placement spot, and the surface the units will stand on.[12][1]
- An electrical certificate of compliance (CoC) and test report for each unit's wiring, issued by a registered person, and a clause in the hire agreement saying whether you or the hire company holds the CoC.[2][3][10][9]
- Power: your supply point, who runs the cable to the container's connector box and, on a construction site, the competent person appointed in writing for temporary electrical installations.[1][9]
- Whether the units stand on a building site or elsewhere, whether the local authority wants plans approved or a temporary-building application, and who applies for it.[4][5]
- For any ablution, change-room or eating units also hired: the number of workers of each sex they must serve.[1]
Questions buyers ask
Is a 6 m container the same as a 20 ft container?
Yes, in hire listings. One Western Cape hire company lists its 3 m units as 10 ft, its 6 m units as 20 ft and its 12 m units as 40 ft, all 2.44 m wide and 2.6 m high, with a 2.9 m high version of the 12 m container.[6]
Does a hired container office come with an electrical CoC?
Some do: one converter says it issues a certificate of compliance on every unit "as standard, not as an add-on", and one hire company says its insulated 6 m office "comes with a wiring certificate". Under the Electrical Installation Regulations, the user or lessor of an electrical installation must have the CoC, though a written undertaking can transfer responsibility for the installation to the lessee (regulations 2 and 7), so settle it in the hire agreement.[2][10][9]
Can workers sleep in a builder's shed?
Security staff may be housed in builder's sheds, subject to conditions that protect their health and avoid nuisance to neighbours; otherwise builder's sheds serve only purposes connected with the building work (regulation F10(3) and (6) of the National Building Regulations as Overstrand Municipality publishes them). For workers far from home without adequate transport or other suitable accommodation, Construction Regulation 30(2) is a separate duty: the contractor must provide "reasonable and suitable living accommodation".[5][1]
