Night curfew rules across the City of Maribyrnong.

Yes. From 1 July 2026 the City of Maribyrnong runs a night-time cat curfew, so cats must be kept indoors or in a secure enclosure between 7pm and 7am every day. During those hours your cat can't be left to roam the streets. A fully enclosed cat run in your own yard is one of the easiest ways to meet the rule, because it keeps your cat safely on your property overnight while still giving it fresh air and outdoor time.

Yes. Under the Domestic Animals Act 1994 and the council's local rules, every cat over three months old must be registered with the council. Registration runs on a yearly cycle and is due for renewal by 10 April each year. You can register through the council's Pet Registrations page or by contacting them directly.

Your cat has to be microchipped before you can register it with the council. Desexing isn't always strictly required to register, but desexed cats pay a lower registration fee and the council actively encourages desexing, with subsidised help available for eligible residents. The council's newer animal management plan is moving toward stronger desexing requirements, so it's worth checking the current rule with the council.

The council's local law lets you keep up to three cats on a standard property before a permit is needed. If you live in a flat, the limit is two. To keep more than that you'll need to apply to the council for an excess-animal permit.

A cat enclosure on its own doesn't need an animal permit. Whether a building permit is needed comes down to size and siting: as a general guide in Victoria, a freestanding enclosure under 10 square metres in floor area and under 3 metres high usually doesn't need one. If yours is bigger, taller, attached to the house or sits close to a boundary, check with the council's building team first.

Yes, the usual Victorian building rules apply. A freestanding enclosure generally needs to stay under 3 metres high to avoid triggering a building permit, and if it's within a metre of a boundary it should be kept under about 2.4 metres. Setbacks and any planning overlays on your property can also come into play, so it's worth a quick check with the council before you start.

If your cat is found roaming, especially during curfew hours, it can be picked up by the council and impounded, and you may face release fees or a fine. A registered, microchipped cat is far easier for the council to reunite with you quickly. Keeping your cat contained at home, either in the house or in a secure enclosure, is the simplest way to avoid the whole situation.

You can, but you'll usually need your landlord's or owners corporation's permission first, since you're altering the property. Freestanding or window-style enclosures that don't need fixing to the building are often the easiest option for renters and apartments. If you're in a flat, remember the council's two-cat limit before a permit is required, and check your lease or body corporate rules.

A fully enclosed catio keeps your cat safely on your property, which is exactly what containment rules ask for, while still giving them fresh air and the sounds and smells of outside. We build a range of escape-proof enclosures, from a discreet patio catio to a side run or netting over the whole backyard, so there's an option to suit your home. Build a quote to get started.
