Removable over-bonnet storage is a practical option for most apartment and townhouse parking bays, provided three things line up: written body corporate consent, adequate sprinkler clearance under AS 2118.1-2017, and a unit footprint that matches your bay. Products like The Kookaburra from Storagenest are built as freestanding, non-permanent units for exactly this scenario. Measure your bay and talk to your building manager before you order anything.
Non-permanent garage storage, in the context of apartment parking, means a freestanding steel unit positioned above your car's bonnet rather than a fixed cage or built-in shelving. It sits on adjustable legs, clears the vehicle when parked, and can be unbolted and removed without leaving a mark on the slab or the wall. That last point matters more than most buyers realise. A body corporate can approve a removable fixture far more easily than a permanent one, because removing it later is not a construction job.
Expect these features on a genuine non-permanent unit:
This design exists because most apartment and townhouse complexes never built storage cages, and retrofitting them is expensive and disruptive. An over-bonnet unit uses air space that's otherwise wasted above the car.
Getting approval starts with understanding what you're actually asking permission for. If your parking bay carries exclusive use rights, you have more standing to install something than if the bay is common property shared with other lots. Either way, consent usually needs to be in writing, and owners corporations increasingly expect a full paper trail before they'll sign off.
Tribunal decisions give a useful steer on how these disputes actually get decided. In Dawn, the tribunal focused less on whether the storage locker counted as a "fixture" and more on whether it interfered with parking use or neighbouring bays. Committees that can see clear evidence of no interference tend to approve faster; vague or undocumented applications get knocked back or reversed later.
A workable application checklist looks like this:
Application templates for car park storage installations typically ask for all five of these, plus confirmation the finished install can be inspected. Committees that skip the inspection step often end up dealing with removal orders months later, once someone complains.
Pro Tip: If you're on a body corporate committee, don't just approve or reject applications. Set conditions upfront, non-combustible materials only, no hazardous contents stored inside, and a written commitment that the unit is removable. That protects the building without blocking a reasonable resident request.
Storagenest publishes a body corporate approval guide that walks through exactly this process for residents preparing an application.
Fire compliance is the single most common reason over-bonnet installations get refused or ordered removed after the fact. Inspectors routinely check clearance from sprinkler heads, and units deeper than roughly one metre can start to interfere with sprinkler discharge paths. This is an issue directly addressed under AS 2118.1-2017, the standard governing sprinkler system design in Australian buildings.
Routine fire safety inspections under AS1851-2012 add another layer. If an inspector flags a storage unit as a new obstruction near sprinkler coverage, some jurisdictions require the building to lodge a Form 12 confirming the fire system still performs to standard. That process can stall or reverse an installation that was otherwise approved by the body corporate.
Before you commit to a unit, take these steps:
Practical guidance on Queensland strata disputes notes that sprinkler proximity and AS1851 reporting are the two issues that most often trip up an otherwise sound application. A building can insist on relocation or removal if a later inspection finds the unit compromises fire coverage, even after initial approval, so get the fire survey done before installation, not after a complaint.
Fit is a measurement problem, not a guessing game. Before you order anything, record these figures:
Park your car in the bay as you normally would, then measure the clear space above the bonnet with a tape measure and mark it out with tape on the wall or floor. A simple diagram showing these measurements strengthens any body corporate application. Adjustable legs on units like The Kookaburra help absorb small variations in slab height, but they can't fix a bay that's genuinely too shallow or too close to a sprinkler head.
Pro Tip: If your door swing or a neighbour's door swing overlaps the unit's footprint by even a few centimetres, treat that bay as unsuitable rather than hoping it won't be an issue. Disputes over door clearance are one of the most common neighbour complaints after installation.
A bay is clearly unsuitable when overhead clearance is under the unit's minimum height requirement, when the unit would sit within the sprinkler protection zone, or when there's no realistic way to access the unit without opening your car door into a neighbouring bay.
A standard professional install follows a predictable sequence: a site check to confirm measurements match the application, written authorisation from the body corporate, then the physical install itself. Storagenest's installation process typically takes under two hours for a standard unit, finishing with a compatibility check and a walkthrough with the building manager if required.
Removal is just as straightforward, since the unit was never bolted to the structure. If a later fire inspection or a change in strata rules requires removal, a professional installer can take the unit down and restore the bay to its original state in a similar timeframe.
Keep these documents on file:
Costs break down into a few clear components: the unit itself (purchase or weekly rental), delivery, professional installation, and any strata application or inspection fees your building charges.
Ask any supplier for the specifics on parts warranty, installation guarantee, and whether a compatibility check is included before you sign anything. Storagenest lists its warranty terms separately from the unit price, which is worth comparing against other options like general storage unit pricing if you're weighing a locker elsewhere against an over-bonnet unit in your own bay.
Steel units built for outdoor or semi-exposed car parks hold up well, but only if you give them basic attention a few times a year. Salt air near coastal buildings, exhaust residue, and general grime all shorten the life of a coating faster than most residents expect.
Wipe down exterior panels every few months with a damp cloth and mild detergent, avoiding abrasive cleaners that can scratch a corrosion-resistant coating. Check the multi-point locking mechanism periodically to confirm it still moves freely. A light spray of silicone lubricant on hinges and locks once or twice a year prevents the seizing that's common in units exposed to humidity.
Inspect the legs and frame joints for rust spots, particularly at the base where moisture pools after rain or car washing. Catching surface rust early, and treating it with a rust converter or touch-up paint, stops it spreading into structural corrosion. If your unit sits near a driveway entrance exposed to weather, consider a light tarp or cover during extended wet periods.
Don't overload one side of the unit. Distributing weight evenly across the frame keeps stress off individual legs and reduces the chance of the unit shifting over time, especially in units without a bolted base. Check that stored items aren't pressing against the panel seams, since constant pressure on a lock point can wear the mechanism prematurely.
A once-a-year check, five minutes with a torch and a cloth, adds years to a unit that's otherwise built to handle daily exposure.
Installing shared storage in a common or exclusive-use parking bay raises a genuine insurance question, and it's one both renters and body corporates should address before installation rather than after an incident.
For body corporates, the building's public liability policy generally covers common property, but a unit installed without proper consent can complicate a claim if someone is injured near it or if it's deemed to have caused damage to a vehicle or the structure. Getting written approval isn't just a strata formality, it's part of keeping the building's insurance position clean.
For residents, home and contents policies rarely extend automatically to items stored outside a locked dwelling. Check with your insurer whether contents stored in a locked, secure unit within your parking bay are covered, and under what conditions, before you assume they are. Some insurers require the unit to be lockable and fixed within a defined exclusive-use area to extend cover; others exclude car park storage entirely.
Liability also runs the other way. If a poorly secured unit or overloaded shelf causes damage to a neighbouring vehicle, the resident who installed it, not the body corporate, typically carries that liability. This is one more reason to keep installation professional, keep load within the rated capacity, and keep documentation, including the installer's insurance certificate, on file in case a dispute arises later.
Getting the ergonomics right makes the difference between a unit you use weekly and one that becomes a nuisance you avoid. Position frequently used items on the lower shelves or front sections where you can reach them without a step stool, and reserve the highest or deepest sections for things you access rarely, seasonal decorations, camping gear, spare tyres.
Respect the weight rating. A frame rated to 500kg total doesn't mean any single shelf or corner should carry that load. Spread heavier items across the base of the unit rather than stacking them toward one side or the top, both for the frame's sake and to avoid a top-heavy unit shifting when you're loading or unloading.
Secure loose items inside the unit rather than relying on the lockable panels alone to keep things in place. Tools, paint tins, and anything with sharp edges should sit in a container or tied down, particularly if the unit is mounted with any tilt or if you're storing items that could shift and fall when you open the panel. A bungee cord or small storage tote inside the main compartment solves most of this cheaply.
Take care when loading or unloading near your car. Since the unit sits directly above the bonnet, dropped tools or shifted boxes have a short, direct fall onto your vehicle. Load and unload with the car either fully parked and switched off, or briefly moved out of the bay if you're handling anything heavy or awkward.
Installers who work across apartment buildings every week develop a simple rule: always run a pre-approval site check before quoting, because bay geometry and sprinkler placement vary more than owners expect. The sequence that avoids wasted time is straightforward. Measure your bay properly, consult the building manager early, commission a fire survey if the unit sits anywhere near sprinkler coverage, then book a professional install.
Pause the plan if the bay geometry is tight, if a sprinkler head sits close to the proposed unit, or if neighbours raise persistent access objections. Those three issues cause more failed installations than any pricing or supplier decision.

Over-bonnet storage units provide an alternative to building a storage cage or renting an offsite unit, designed for apartment and townhouse residents whose car park is the only unused space available. These units turn the airspace above your bonnet into several cubic metres of secure, lockable storage, without touching a single wall or slab.
Every unit is built from corrosion-resistant, all-steel panels with multi-point locking security, and the frame carries substantial load capacity, enough for tools, camping gear, and seasonal boxes that would otherwise clutter a hallway cupboard. Professional installation takes under two hours, and the team runs a compatibility check against your bay's measurements before anything is delivered. You can buy outright or rent from $25 a week, whichever suits your tenancy, and every purchase comes with a Lifetime Parts Cover.
None of this replaces your building's own fire and strata checks, and Storagenest's body corporate approval support is built specifically to help you get through that process rather than skip it. Start with a compatibility check on the Storagenest website to see whether your bay qualifies for The Kookaburra.
Yes, in almost every strata or owners corporation scheme, written consent is required before installing any storage unit in a shared or exclusive-use parking bay.
Yes, if the unit's depth or position interferes with sprinkler coverage under AS 2118.1-2017, inspectors can require changes or refuse the installation until clearance is confirmed.
Renters can install a non-permanent unit, but approval typically needs to come from the property owner and the body corporate, since the bay itself is common or exclusive-use property.
A standard professional install, like Storagenest's process, is typically completed in under two hours, including a compatibility check.
Tribunal cases such as Dawn show that objections are weighed against actual interference with parking or access, so a well-documented application showing no impact improves your chances of approval.
