Parkside’s median house price crossed $1.78 million in 2026. For homeowners who bought in the suburb’s residential streets 15 or 20 years ago, that represents a significant asset — and when children have grown and a four-bedroom family home is genuinely surplus to requirements, the financial case for downsizing is compelling. The inner southern suburbs around Parkside, Malvern, and Fullarton have been seeing sustained downsizer movement for several years: proceeds from a large home partly reinvested into a quality unit close to Unley Road, the park lands walking access, and Adelaide’s CBD.
The security adjustment that comes with this move is something I see managed well and managed poorly in roughly equal measure. Downsizers often arrive at a Parkside unit with very well-developed security habits from a standalone house — habits that don’t translate directly to apartment or unit living. And they sometimes find that the security standard of the unit they’ve moved into is meaningfully different from what they assumed when they signed the contract.
This guide is specifically for people making the transition from a Parkside or inner suburban house to a unit or apartment. It covers what’s different, what to check, and what’s worth investing in early.
What Changes When You Move From a House to a Unit
The most fundamental security difference between a standalone house and a unit in Parkside is the shared perimeter. In a house, you control every external access point: front door, rear door, side gates, garage. You know what hardware is on each one. You decide when it was last rekeyed.
In a unit or apartment, your individual perimeter is only the entry door to your unit (and any private external doors to a balcony or courtyard). Everything outside that — the building entry, the common stairwell, the car park, the bin enclosure — is shared perimeter managed by the owners corporation.
This matters practically because the security chain is only as strong as its weakest link. A unit entry door with a high-quality deadbolt is still accessible via the building’s common entry, which may have a fob system where some fobs have been lost and never deactivated, a key-operated intercom that was re-keyed three years ago, or a door that regularly doesn’t close properly.
The second major difference is that in a unit, you don’t control the rekeying of your entry door unless you’re the current owner and you initiate it. Many strata buildings have a master key arrangement — a single key (held by the strata manager, the building manager, and potentially the on-site caretaker) that opens all units. Understanding this arrangement is important information for a new unit owner.
Questions to Ask Before Settlement (or Immediately After)
If you’re a Parkside unit owner who has recently settled — or who is about to — these are the questions worth asking before or immediately after taking possession.
When was my unit’s entry door lock last rekeyed?
If the property has been sold before — which is likely in Parkside’s active resale market — the previous owner had a key, their real estate agent had a key, and potentially tradespeople who worked in the unit had a key. In a building with a master key system, additional parties may also have access. A rekey at settlement is not an overreaction — it’s standard prudent practice for any property change-of-ownership.
Is there a master key for this building, and who holds it?
Ask the strata manager. Get the answer in writing. Understanding who can access your unit, under what circumstances, and with what notification is relevant information — both for security and for your peace of mind.
What is the key or fob situation for common areas?
How many key copies or active fobs exist for the building entry? Has the building common entry been rekeyed or refobbed recently? In an older Parkside apartment block, the answer may be that the common entry system hasn’t been reviewed in years and there are an unknown number of active access credentials in circulation. This is a matter for the strata committee or building manager, but raising it is appropriate.
What security hardware is on my balcony or courtyard door?
If your unit has a ground-floor or low-level external private space, the door or gate providing access to it may be the weakest security point in your unit — potentially more accessible than your front entry door. Check it on the day you take possession.
The Rekey Decision: Do It at Settlement
I recommend to every downsizer moving into a Parkside unit that they arrange a rekey of their entry door at or immediately after settlement, without waiting for a specific reason.
The logic is straightforward: you cannot verify the key history of the unit without access to records that may not exist or may not be complete. Previous owners, their family members, real estate agents, cleaners, contractors — any of these people may have a copy of the key that opens your door. A rekey closes that history completely. You start your tenancy or ownership with certainty about who has keys to your home.
In a standard Parkside unit with a single entry door, a rekey typically takes 30 to 45 minutes and costs between $80 and $150 depending on the cylinder type. This is a one-time investment at the moment of transition — significantly cheaper and simpler than managing the anxiety of uncertain key history for the next several years.
Some sellers and their agents will provide documentation of a rekey at settlement as standard practice. Many don’t. If it hasn’t been confirmed, initiate it yourself.
Pro Tip: When you arrange a rekey, consider whether the new cylinder should be a restricted key profile — one that can only be cut by a licensed locksmith with your authorisation. This prevents future key copies being made without your knowledge, which is relevant if you have a cleaner, a caregiver, or a family member with regular access.
Common Security Oversights in Parkside Unit Living
Beyond the rekey, there are specific security oversights I consistently find in Parkside units occupied by downsizers — patterns that reflect habits developed in a standalone house context that don’t quite transfer.
The balcony or sliding door habit
In a house, you lock the back door. In a unit on the second floor, the sliding door to the balcony feels like it doesn’t need to be locked — you’re above street level, there’s no external access. This is partly true and partly not. A second-floor balcony accessible from an adjacent balcony, a drainpipe, or a courtyard below is not as inaccessible as it seems. A sliding door left on the latch rather than locked is also, in some configurations, vulnerable to being lifted off its track from outside. Lock the sliding door. It takes three seconds and costs nothing.
The storeroom or car park
Many Parkside units come with a locked storeroom in the basement or a car park space secured by a roller door. These common areas are part of the shared perimeter and their security depends on the building’s common access controls. Items of value stored in a basement storeroom should be locked within that storeroom — don’t rely solely on the building’s common entry being adequate.
Leaving the common entry door propped
In a building where residents come and go for deliveries or are carrying shopping, the temptation to prop the common entry door is real. This eliminates the building’s primary perimeter security. It’s a habit worth resisting — and one worth raising with neighbours and the strata committee if it’s a recurring pattern.
Security camera awareness
A growing number of Parkside apartment buildings are installing or upgrading security camera systems. Understanding where cameras cover — and, more importantly, where they don’t — in your building’s common areas is useful information. A camera that covers the front entry but not the car park level doesn’t protect your vehicle.
The Strata Layer: What Belongs to the Building, What Belongs to You
One source of confusion for downsizers new to strata living is understanding which security decisions are theirs to make and which belong to the owners corporation.
Security decisions that are yours as a lot owner: the lock on your unit entry door (subject to any strata by-laws about lock types — worth checking), any locks on doors or windows within your lot, any private external space such as a courtyard gate.
Security decisions that belong to the owners corporation: common area lighting, the building entry system (intercom, key fobs, electronic access), building CCTV, common stairwell or corridor security, the car park access system.
If you want to raise building security matters — a poorly lit car park, a building entry that doesn’t close properly, an intercom system that’s been malfunctioning for months — the right channel is the strata committee and/or the strata manager. These issues can be raised formally at an AGM or as an urgent maintenance matter depending on severity.
Coming from a standalone home where every security decision was yours to make unilaterally, the strata process can feel slow. But it’s the appropriate channel, and a well-run Parkside strata should be responsive to legitimate security maintenance concerns.
A Conversation Near Greenhill Road
I was engaged by a couple who had moved from a large family home in Malvern into a two-bedroom unit in a Parkside building near Greenhill Road. They’d settled six weeks earlier, hadn’t rekeyed, and were calling because they’d found an unfamiliar key on their doorstep — presumably a key to something in the building, unclear what.
When I inspected the entry door, the existing cylinder was the original builder-grade hardware — a basic profile that had clearly been in place since the building was constructed. It had never been upgraded. The building had changed hands as a rental unit twice before the current owners purchased it, and based on the strata records the strata manager could access, the lock had never been rekeyed.
We upgraded to a quality restricted-profile cylinder. The couple received three keys; any future copies require a licensed locksmith and their authorisation.
We also inspected the balcony door, which was a sliding door with a standard lever handle — no additional security measure. I fitted a secondary security bar in the track, which prevents the door being lifted off the track from outside and also prevents it being opened if the primary lever handle latch is defeated.
Their comment: “We thought units were simpler from a security point of view. We didn’t realise there were things we’d have to sort out ourselves.”
That’s the most common misconception I encounter in this transition. A unit is not inherently more secure than a house — it’s just differently complex.
