Deck & pergola rules in Hobart
City of Hobart assesses these under the Tasmania rules below. Heritage, flood or bushfire mapping on your own lot can change what you need to apply for.
Low decks are 'low-risk work' with no building permit
A deck less than 1 m above the ground is 'low-risk work' in Tasmania: no building permit and no building surveyor needed, and an owner or competent person can build it, though it must still comply. At 1 m or more above ground it becomes 'notifiable work' and needs a building surveyor. Pergolas up to 18 m² and 3.5 m are also low-risk.
Key rules at a glance
| Deck low-risk (no permit) | Less than 1 m above the ground or trafficable surface below |
| Deck notifiable | 1 m or more above ground - needs a building surveyor (notifiable work) |
| Pergola low-risk | Roofless, 18 m² or less and 3.5 m or less high |
| Who can build | Low-risk work can be done by the owner or a competent person |
| Compliance | Must still meet the National Construction Code and the Building Act |
| Planning | A planning permit may still be needed on heritage, flood or bushfire overlay land |
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application, even when the general rules say you're fine.
How often this applies in Hobart
These are the overlays that can remove the fast-track, measured across every parcel in Hobart from the same data behind our zoning map. They describe the council, not your block, and they are counted separately — one parcel can carry more than one, so they cannot be added together.
| Overlay | Share of parcels | What that means here |
|---|---|---|
| Heritage | 43.28% | 10,392 parcels flagged. 56.72% of the council has no heritage mapping, so we can't say for those parcels. |
| Flood | 7.99% | 1,919 parcels flagged. The rest are mapped and sit outside it. |
| Bushfire | 23.39% | 5,616 parcels flagged. The rest are mapped and sit outside it. |
The most common zone in Hobart is General Residential, covering 41.1% of its 24,011 parcels. What you can build is decided by your own lot's zone, not the council's most common one.

Frequently asked questions
Do I need council approval for a deck or pergola in Hobart?
Often not. Tasmania allows a deck or pergola to proceed without a full development application when it meets the standards, and City of Hobart follows that framework. But local overlays — heritage, flood or bushfire — can remove the fast-track, so check your exact address before you rely on it.
Which council approves a deck or pergola in Hobart?
City of Hobart is the consent authority for Hobart (Greater Hobart). You can review local planning controls on the council website and lodge through your state planning portal.
Do I need a permit to build a deck in Tasmania?
Not for a deck less than 1 m above the ground, which is low-risk work needing no building permit or building surveyor. A deck 1 m or more above the ground is notifiable work and must be handled by a building surveyor.
