Adding a Deck to a Rental Property: Cost, ROI & Smart Landlord Tips

You are looking at your rental property, wondering whether slinging up a deck is actually worth the hassle and cash. The short answer is yes. But like most things in property investment, the devil’s in the details, and there’s a right way and a spectacularly wrong way to go about it.

A Remodeling Impact Study by the National Association of Realtors and Landscape Professionals found that a new wood deck will recover 106% of its value if you sell your rental. This, and a stack of other benefits that we’ll discuss in this article, make the addition of a fresh deck a very compelling case.

Choosing materials for the long-term

Everyone gets excited about a timber deck and rushes in without considering the long-term upkeep and maintenance of a deck..

Timber looks brilliant initially, offering a lower upfront cost, an excellent return on investment, and decent aesthetic appeal. But it’s high maintenance. There’s mandatory annual oiling or staining, board replacements when things go pear-shaped, and risks from termites, wet rot (if it’s constantly damp), and general management headaches.

Timber gives you 10-15 years max before you’re looking at major works again. With quality composite decking, however, you’re getting 20-30 years out of it, easy. Yes, you’re paying more upfront, but you’re essentially buying yourself out of a decade and a half of maintenance scheduling, contractor wrangling, and unexpected repair bills. Composite materials just sit there looking good, requiring nothing more than the occasional clean. They don’t crack, split, fade, or run the risk of termites. For a genuinely passive investment, composite wins hands down.

The rental market advantage

Tenants absolutely love outdoor space. In competitive rental markets, a quality deck is a genuine differentiator that can command premium rent and slash your vacancy periods.

Think about it from a tenant’s perspective. Two similar properties, same price range, but one’s got a beautiful deck flowing off the living area, and the other’s just got a patchy lawn. Which one are they choosing? The deck wins every time, especially if it’s set up as an all-weather entertaining area.

Properties with quality outdoor entertaining spaces fill faster and hold tenants longer. That translates directly into better yield and fewer headaches. Every week your property sits empty is money you never get back. A deck that reduces vacancy by even a few weeks pays for itself quickly.

The compliance minefield you can’t skip

Lots of investors get absolutely burned by cutting corners here. Building permits aren’t optional; they’re mandatory for any structural work, including decks.

In some locations, you generally don’t need a planning permit if your deck’s finished floor level is less than 800mm above ground. Go higher than that, and you’re into permit territory. If your project costs more than a certain amount (dependent on location), you legally need a registered builder doing the work.

Setback requirements are another trap. Your deck and stairs must maintain minimum distances from property boundaries, and these requirements might differ from what was allowed when your house was built. You also need to factor the deck into your property’s total site coverage calculations. Push past the allowable percentage, and you’re looking at expensive variance applications or, worse, being told to tear the whole thing down.

Get a structural engineering sign-off, especially if you’re attaching the deck to your primary dwelling. It needs to handle the loads (people, furniture, plants) without compromising the existing structure. We also strongly recommend that you inform those in charge of your landlord insurance and your agent about this and any additions you make.

Playing the tax game to win

The tax treatment of your deck is where you can really optimize returns, but you need to understand the rules. A new deck is a capital improvement, not a repair. This means you can’t just deduct the entire cost immediately; you need to depreciate it over time.

The main structure (piling, subframe, fixed boards) gets claimed as Capital Works at a certain percentage per year over 40 years. Sounds slow, but it’s a reliable income tax reduction year after year.

To ensure you choose the sophisticated option, get a quantity surveyor involved. They can identify components that qualify as separately depreciating assets rather than structural improvements, like built-in seating or certain non-fixed elements. These items depreciate over 10 or 20 years instead of 40, accelerating your deductions and improving early-year cash flow.
