Letterboxes in the lobby of a residential strata building, a common target in apartment building security

Building security guide

Strata security

A practical guide for owners corporations, strata committees and building managers.

Strata security is how an owners corporation protects the residents, property and common areas of an apartment or mixed-use building. In most buildings the weak points are not the locks but the way access is managed: fob registers that are out of date, car park doors that stay open too long, parcels left in open lobbies and cameras that nobody checks. A walk-through of the building, once by day and once after dark, finds most of them.

  • The owners corporation is responsible for the security of common property; each owner is responsible for their own lot.
  • Most strata security gaps come from access management: keys, fobs, doors that do not close, and tailgating.
  • CCTV on common property needs the approval your state’s strata law requires, and a clear policy on who can view footage.
  • Parcel and mail theft, and tailgating into the building and car park, are among the problems strata committees most often bring to Agilient, and each needs an answer that fits the building.
  • Never lock or block a fire exit to improve security.

Download the free strata building security checklist

Agilient’s free Word checklist walks a committee or building manager through the building: the street frontage, entry doors and fobs, car parks, mail and parcels, lighting, CCTV, plant rooms, contractors and incident records. Each check is marked Yes, Partly or No, and the summary turns the gaps into a short action list the committee can approve.

Responsibility

Who is responsible for strata security?

The owners corporation (called a body corporate in some states) owns and manages the common property: entries, lobbies, car parks, lifts, stairs, gardens and shared facilities. Its strata committee makes most day to day decisions, and a strata manager or building manager usually carries them out. Larger changes, such as new access control or cameras on common property, are generally decided by the owners at a general meeting and paid for from the scheme’s funds.

Lot owners are responsible for their own apartment, including its door and windows. Tenants follow the by-laws. Security works best when the committee sets clear rules, the building manager applies them, and residents understand why they matter.

Common gaps

What are the most common security problems in apartment buildings?

Keys and fobs

Fobs that were never cancelled when a tenant left, lost fobs still active, and no register to check against.

Car parks

Vehicle doors that stay open long enough to walk in, gaps beside the door, dark corners and flimsy storage cages.

Mail and parcels

Letterboxes in uncontrolled areas and parcels left in open lobbies, an easy and repeated target.

Tailgating

Residents holding doors for people they do not know, and doors propped open for moves and deliveries.

Lighting

Failed or poorly placed lights at entries, paths and bin areas that leave places to wait unseen.

CCTV nobody checks

Cameras with poor images, wrong clocks or full recorders, discovered only when footage is needed.

Deliveries and mail

Why do parcels and mail go missing in apartment buildings?

Online shopping has turned the lobby of many apartment buildings into an unattended storeroom. Parcels arrive through the day, often while residents are at work, and they are left wherever the driver can reach: the lobby floor, the mail room, a corridor or outside a front door. Anyone who gets into the building can pick them up, and many thieves were let in by someone else.

The problem usually has several causes at once:

  • Delivery drivers are let in by residents who do not know them, given a shared code, or follow someone through the door.
  • Parcels are left in open lobbies or corridors, with nothing to show who collected them.
  • Letterbox banks are in areas the public can reach, or have weak locks that can be forced or opened with copied keys.
  • The mail area sits outside camera coverage, or the footage is too poor to identify anyone.
  • Large items, such as furniture and appliances, are left in loading docks or car parks.

The losses fall mostly on residents, so parcel and mail theft quickly becomes a source of complaints and disputes for the committee. Parcel lockers, a controlled delivery room, changes to courier access and a concierge each have a cost, a capacity limit and an effect on convenience, and what suits one building will not suit the next. Getting it right starts with understanding how deliveries actually arrive, where they go and who can reach them.

An independent building security review maps the delivery and mail routes through the building and tests the options against its layout, delivery volume and budget.

Tailgating

What is tailgating, and why does it matter in strata buildings?

Tailgating is following an authorised person or vehicle through a secure door before it closes. It is a common way for unauthorised people to get into apartment buildings, and it defeats the access control system the owners corporation has paid for, because no fob is ever presented.

Car parks are especially exposed. A vehicle door that takes a long time to close lets a second car, a person on foot or a bicycle follow the first one in. Once inside, an intruder can work through cars, storage cages, bicycle racks and letterboxes out of sight, and if the lifts and stairs from the car park are not controlled, can reach the residential floors as well.

Tailgating happens for reasons that are easy to understand and hard to change:

  • Residents hold doors open out of politeness, or to avoid a confrontation.
  • Vehicle doors are set to close slowly so they do not hit cars, which leaves a long window to walk in.
  • Doors are propped open for moves, deliveries and contractors.
  • In a large scheme, residents cannot tell a visitor from an intruder.
  • Cameras record people coming in but do not stop them, and footage is often only reviewed after a loss.

The risk is not only theft. People who get in unchallenged may sleep in stairwells or car parks, damage property or confront residents, and residents who feel unsafe in their own car park or corridor bring that concern to the committee. Reducing tailgating usually takes a combination of door hardware and timing, the layout of entries and lifts, how visitors and contractors are managed, and resident awareness, and every change has to be checked against fire safety and accessibility requirements.

The right combination depends on the building. Agilient’s independent review looks at how people and vehicles actually move through the entries and car park, and recommends the changes that will make a difference for the cost.

How to check

How do you check a strata building’s security?

A committee can do a useful first check without specialist equipment. The aim is to see the building the way an opportunist would, then agree a short list of fixes.

  • Walk it twice. Once in daylight and once after dark, starting at the street and working inward to the car park, mail area, lifts and plant rooms.
  • Test the doors. Every external door and gate should close and latch on its own. Time the car park door after a car passes through.
  • Reconcile the fob register. Compare the register with the access control system and cancel any fob that cannot be accounted for.
  • Read the incident log. Look for patterns by place and time. If there is no log, start one.
  • Check the cameras. Play back footage from last week, check the date and time, and confirm someone knows how to export it for police.
  • Agree priorities. Fix the cheap and fast items first, and get advice and quotes for the larger ones.

The way a building is laid out affects how easy it is to misuse. Agilient’s guide to crime prevention through environmental design explains how sight lines, lighting and landscaping help, and the guide on how to assess building security covers the wider method.

CCTV

Can an owners corporation install CCTV in a strata building?

Yes, but cameras on common property must be approved in the way the state’s strata law requires. In NSW this is usually a special resolution at a general meeting, often with a by-law that sets out where cameras may go and how footage is managed. A by-law change must be registered with NSW Land Registry Services within six months of the resolution, or the resolution must be passed again.1 Other states have their own strata legislation, so the committee should check the rules that apply before buying equipment.

Surveillance devices laws in every state restrict recording private conversations and private activities, so strata cameras should record video only and should not look into lots, windows or balconies.2 A short written policy should say who can view footage, how residents and police request it, and how long it is kept.

Image quality matters as much as approval. A camera at the main entry should produce an image clear enough to recognise a face, day and night, which is the kind of requirement the AS/NZS 62676 series of video surveillance standards helps specify. If a system is ageing, the CCTV upgrade guide sets out the options and the free CCTV health check gives a quick first read.

Independent advice

When should a strata committee get an independent security review?

  • There have been repeated break-ins, car park thefts or people found inside the building.
  • The owners corporation is about to spend significant capital works funds on access control, intercoms or CCTV.
  • Contractor quotes disagree, or the committee is unsure whether a proposal fits the building.
  • An insurer has asked for a security assessment.
  • Residents disagree about cameras and privacy, and the committee needs an independent view to take to a general meeting.

FAQs

Strata security FAQs

Who is responsible for security in a strata building?
The owners corporation is responsible for the common property, including entries, car parks, lifts and shared facilities. The strata committee makes most day to day decisions on its behalf, and a strata or building manager often carries them out. Each lot owner is responsible for the security of their own lot.
How can a strata building reduce parcel and mail theft?
Start by understanding how deliveries arrive, where parcels are left and who can reach them. Options include parcel lockers, a controlled delivery room, rules for courier access, stronger letterboxes in a controlled area and better camera coverage of the mail area. Each has a cost and a capacity limit, so the right choice depends on the building.
How do you stop tailgating into an apartment car park?
No single measure stops it. The closing speed of the vehicle door, gaps beside it, fob control on the lifts and stairs from the car park, separate visitor parking and resident awareness all play a part. Any change to doors must be checked against fire safety and accessibility requirements, and an independent review identifies which measures matter in a particular building.
Can an owners corporation install CCTV on common property?
Yes, but it must be approved in the way the state’s strata law requires. In NSW, cameras on common property are usually authorised by a special resolution at a general meeting, often with a by-law that sets out where cameras go, who can view footage and how long it is kept. Other states have their own rules, so check before installing.
How often should a strata building review its security?
A walk-through once a year is a sensible minimum, and sooner after a run of incidents, a change of building or strata manager, or before spending capital works funds on access control or CCTV. Reviewing incidents at every committee meeting helps spot patterns early.
What is the cheapest way to improve apartment building security?
The quickest wins are usually administrative and low cost: reconcile the fob register and cancel unaccounted fobs, adjust door closers and the car park door timing, fix lighting, and move parcels out of open lobbies. These often matter more than new equipment.
