Strata and Mixed-Use Buildings: A Bin Plan That Survives Real Tenants

Shared bin areas do not fail because the bins are too small. They fail because nobody owns the rules: the cafe's food waste ends up in the office tenants' bin, cardboard arrives unflattened, the recycling gets contaminated by whoever walked past, and the strata committee argues about whose collection bill it is. A working plan settles four things in writing: what bins exist, who may use which, how costs split, and what happens when someone breaks the rules.

Start from the tenant mix, not the bin room

A mixed-use building's waste profile is the sum of very different businesses. Food tenants produce heavy, wet waste daily. Offices produce light, dry waste that barely fills bins. Retail produces cardboard above all. The honest structure follows from that:

• Food tenants get their own general waste bins, and where the stream is bookable (Sydney and Wollongong, Adelaide), their own food organics bin. Food waste in shared bins is the number one source of odour complaints and cross-tenant disputes.
• Dry tenants (offices, services) can share general waste and, where available, commingled recycling.
• Cardboard gets a rule everywhere: flattened, always. In Adelaide a dedicated cardboard bin is bookable; elsewhere flattening protects the shared general capacity.

On whether to run fewer big bins or more small ones per tenant group, the bin count vs bin size guide for strata works through the trade-off.

The four rules worth posting on the bin room wall

1. Flatten cardboard. Whole boxes are air and fill shared capacity fastest.
2. Nothing next to the bins. Waste on the floor is a pest and access problem, and it is how collection lifts get missed.
3. Recycling is unforgiving. No bagged waste, no coffee cups, no soft plastics. One tenant's mistake voids everyone's lift: the contamination guide is the reference.
4. Lids closed. Rain weight, odour and overflowing appearances all start with an open lid.

Signage works best with photographs of the building's actual waste rather than generic icons, and a named contact for questions beats a strata email address nobody reads.

Splitting costs without the annual argument

Three models work, in rising order of fairness and admin:

• Equal split through strata levies: simple, defensible only when tenants have similar waste profiles.
• Weighted split by tenancy type: food tenants pay a higher share by agreement, reflecting their real volume and weight. This is the sweet spot for most mixed-use buildings.
• Direct billing per tenant group: each business or group books its own bins for its own volume. Through Bin Hire Australia each booking is priced for the address and business type and invoiced directly by the local provider, which makes this model straightforward: the cafe pays for the cafe's bins, full stop.

Direct billing also solves the incentive problem: a tenant who pays for their own capacity flattens their own cardboard.

Access, security and the dumping problem

Publicly accessible bins collect the neighbourhood's rubbish. If the bin area fronts a laneway or car park: keep it gated or locked between collection days, mark bins by tenancy, and in Perth a lockable bin option (chain and coded padlock) can be added at booking. Make sure the collection truck can actually reach the bins on the day: blocked bin rooms and parked-over access points are the most common cause of missed lifts in shared buildings.

For building and facilities managers running several sites

The same governance template applies per building, but each building should be priced for its own address: route density and available streams differ by suburb and state. The multi-site playbook covers the review cadence; the Sydney strata guide adds the NSW specifics, including where the FOGO mandate touches buildings with food tenants.

Set the building up properly once

Run the building's address and tenant mix through the quote flow: exact per-collection pricing for the right bin set in about two minutes, free to book, with a vetted local provider delivering, collecting weekly and invoicing directly. Then put the four rules on the wall and enforce them from week one, while nobody has habits to defend.
