Lock and Security Requirements for Rental Properties in Tasmania

Where Locks Fit in the Minimum Standards

Tasmania's Part 3B minimum standards don't include a standalone lock or deadlock requirement. External doors and window frames are included under structural soundness (s. 36I), and fixtures and fittings must be in good repair (s. 36J). Assess a faulty lock or latch under those broader duties; the Act does not specify that every lock failure automatically breaches a particular standard.

Ventilation (s. 36O) — where an openable window is the sole ventilation source for a room, it must be capable of being locked in an open position with a gap of at least 15 cm. This allows airflow while maintaining security against intruder entry.

Beyond Part 3B, the general duty under Section 36 to provide premises in "good repair" may apply to locks, latches and security fittings.

Practical Lock Checks

Part 3B has no standalone lock or deadlock standard and does not specify a lock type for every external entry point. As a practical security check:

• Front and back doors — check that tenants can secure the doors from inside and outside. The Act doesn't specify deadlocks by name.
• Windows — check that windows close and latch; ground-floor windows and windows accessible from shared areas need particular attention.
• Sliding doors — check that the latch or lock holds the door closed.

For ventilation windows that must remain openable, the 15 cm locking mechanism is a specific Part 3B requirement. A window that only has two states — fully open or fully closed — doesn't comply if it's the room's sole ventilation source.

Key Management

Section 55 protects a tenant's quiet enjoyment and the Act sets entry-notice rules. As a practical handover matter:

• Provide working keys or access devices for the locks tenants need to use.
• If a lock is changed, keep the tenant's lawful access intact and give them the necessary updated key or access device.
• Keep key arrangements consistent with the tenant's quiet enjoyment and the statutory entry-notice rules.

Lock Changes During a Tenancy

Before changing locks, confirm the applicable tenancy rules, especially where safety concerns are involved. Tenant access, quiet-enjoyment rights, and entry-notice rules still apply.

Broken Locks and the Repair Clock

The 24-hour urgent-repair rule applies to essential-service failures such as water, sewerage, electricity, the fixed living-area heater, cooking stove, and hot water; a lock failure is not one of the listed categories. Do not assume a broken lock automatically triggers the 24-hour deadline or tenant self-help reimbursement right. General non-essential repairs have a 28-day period, but a particular lock problem must be assessed under the applicable repair duties.

Practical Recommendations

• Pre-tenancy check: test every external lock before handing over keys. Include lock condition in the ingoing condition report and take photographs.
• Window security locks: install restrictors on ventilation windows that allow the 15 cm gap required by Section 36O while preventing the window from opening further.
• Key register: document how many keys exist for each lock and which keys were issued to the tenant. This prevents disputes at the end of the tenancy.
