Confidence is currency in the off-the-plan apartment market.

A developer’s track record is paramount. If they’re new to the scene, their personal background and the calibre of their partners—architects, builders, planners—can offer strong indications of the project's likely success.

Now, a new layer of buyer assurance is emerging: Latent Defects Insurance (LDI).

INCA Property Group is among the latest developers to adopt this rigorous form of protection, securing LDI through Resilience Insurance for its boutique St Ives development, Ellis Residences.

Currently under construction by GOP Constructions, Ellis Residences will comprise 18 three-bedroom apartments, nestled in a quiet cul-de-sac just moments from St Ives Village.

INCA Development Manager Michael Downs says the team first encountered LDI during their Waitara project, but couldn’t proceed at the time, as construction was already too far advanced.

"By the time we were planning Ellis, our builder was proactively asking for it," Downs says. "It gives them certainty, it gives us confidence—and ultimately, it protects the buyer in a way that traditional strata bonds can’t. By the time it’s complete, we know any structural concerns for the next 10 years are covered. It’s a cleaner, more accountable way to do things—the builder can move on, and the buyer isn’t left chasing defects years down the track."

INCA’s Sales and Marketing Manager, Mat Cassidy, says that while LDI may not be widely understood by buyers just yet, it’s a game-changer once explained.

"When we invited our local agent network to preview Ellis before launching sales, the key topic of conversation was how to explain Latent Defects Insurance to buyers," Cassidy says. "We had the Resilience Insurance team on hand to answer questions and break it down. Once it was explained, the value really hit home."

Cassidy describes LDI as "a new benchmark for buyer protection" and says its impact goes beyond post-settlement peace of mind.

"There are monthly or even bi-monthly inspections by a third-party Technical Inspection Service. What the builder delivers isn’t just acceptable to the developer—it has to meet the insurer’s standards. That level of scrutiny benefits everyone."

Even in the event that something does arise post-completion, Cassidy says the process is refreshingly simple for buyers.

"If something goes wrong within the first 10 years, buyers aren’t left fighting for a resolution. They just call the insurer. That’s what we love—peace of mind for everyone involved."

Ellis Residences is currently one of the only developments in the Ku-ring-gai local government area to offer Latent Defects Insurance.

Cassidy confirms INCA plans to roll out LDI across all future apartment projects.

"It’s a must for us—we’re committed to doing the right thing by our buyers," he says. "Without buyers, there are no new projects, so their needs and expectations come above all else."

What is Latent Defects Insurance?

Latent Defects Insurance is a 10-year structural warranty that protects apartment buyers from major defects in structural elements, waterproofing, and core building systems such as electrical and plumbing.

It differs from traditional strata bonds in that it’s developer-purchased and activated immediately upon completion. It also includes independent inspections throughout construction to help catch issues early.
