Victoria Rental Lighting Requirements: Natural and Artificial Light Standards

What Standard 13 Requires

Standard 13 in Schedule 4 of the Residential Tenancies Regulations 2021 has two parts: interior rooms, hallways, and corridors must have adequate natural light by day (including borrowed light) and adequate artificial light by night.

"Adequate" means the area has natural light during the day. This can include light borrowed from an adjoining room; the standard does not give a single glazing-area percentage for every room.

At night, rooms, hallways, and corridors must have access to artificial light that makes them functional.

Where This Standard Typically Fails

Basement conversions and below-grade rooms: A room below ground level with no windows or a small window well may not have adequate natural light. Borrowed light through internal glazing can help, but the adjoining room must itself have adequate natural light.

Internal rooms in apartment conversions: When a larger space is subdivided, the new internal room may have no external wall and therefore no natural light source. These rooms either need internal glazing that borrows adequate light from an adjoining room, or they may need to be reclassified as non-habitable (storage, utility) in the condition report and marketing materials.

Burnt-out or missing light globes: This sounds trivial, but a room with a light fitting and no working globe fails the artificial lighting requirement at the condition report stage. Replace globes before the pre-advertising audit.

Heritage-listed properties: If the property is registered under the Heritage Act 2017, a formal exemption may apply to the lighting standard where heritage restrictions prevent window alterations. This exemption requires documentation from Heritage Victoria or a Municipal Building Surveyor — you cannot claim it informally.

Borrowed Light: When It Counts and When It Doesn't

Borrowed light is natural light that reaches a room from an adjoining room. The minimum standard allows it to count toward the daytime natural-light requirement when:

• The source room has adequate natural light of its own
• The adjoining room provides adequate natural light for the area receiving borrowed light

A common scenario: an open-plan living and kitchen area where the kitchen section has no external windows but receives light from the living area's windows. If the living area has adequate glazing, the kitchen satisfies Standard 13 through borrowed light. But if the two areas can be closed off with a door or partition, the kitchen needs its own assessment.

Practical Audit Steps

Walk through the property at two different times:

• Daytime: With all artificial lights off, check whether every room has usable natural light. Note any rooms that feel dark or rely entirely on adjacent rooms with doors open.
• Evening: Turn on every light fitting. Confirm each room, hallway, and corridor has at least one working light. Check stairwells, laundries, and garage entries.

Photograph each room in both conditions. These photos form part of your compliance evidence under Section 65F.

Electrical safety overlaps here: during the biennial electrical safety check, the licensed electrician tests all light fittings and wiring as part of the switchboard and circuit audit. A failed light circuit may indicate wiring issues that affect both Standard 9 (electrical safety) and Standard 13 (lighting).

The Victoria Rental Minimum Standards Compliance Guide covers Standard 13 lighting alongside all 15 categories in a structured audit format, so you can document natural and artificial lighting compliance as part of one complete property walkthrough.
