Bought a Home with Unconsented Building Work? Don't Panic – Here's What You Need to Know

If you've ever looked through a LIM report or spoken with your lawyer during a property purchase, you've probably heard the words "unconsented building work." For many people, that's enough to make them question whether they should walk away from the property altogether.

The reality is, unconsented work is far more common than most people realise.

Over the years, we've inspected hundreds of homes throughout Auckland where alterations have been completed without the correct paperwork. Sometimes it's a deck, a converted garage, an extra bathroom, a sleepout, or an extension that was built years ago. In many cases, the workmanship is actually very good—the paperwork just never caught up.

The good news is that, in many situations, there is a path forward.

What is a Certificate of Acceptance (COA)?

A Certificate of Acceptance (COA) is issued by your local council when building work has already been completed without a building consent, or where the original consent documentation can't be produced.

It's important to understand that a COA isn't simply a piece of paperwork that gets handed out. Council still needs to be satisfied that they have enough evidence to determine whether the completed work complies with the Building Code.

Because the work is already covered up, gathering that evidence is often the biggest challenge.

Not Every Situation Is the Same

One of the biggest misconceptions we see is that every unconsented structure automatically needs to be demolished or rebuilt.

That simply isn't true.

Every property is different.

Some projects require very little additional information, while others may need further investigation, engineering input, plumbing certificates, electrical documentation, or even small remedial works before council is satisfied.

The key is understanding what you're dealing with before spending money unnecessarily.

That's Where We Can Help

At Pinnacle Home & Building Inspections, we regularly help property owners work through the COA process.

Rather than simply pointing out that work appears to be unconsented, we help identify what information is likely to be required and guide owners through the process from start to finish.

Depending on the project, this may include:

• Inspecting the existing work.

• Preparing professional building reports for council.

• Identifying areas that may require further investigation.

• Coordinating with engineers, plumbers, electricians and other licensed trades where required.

• Assisting with council requests for further information.

• Helping manage the application through to completion.

Having someone who understands both construction and council processes can make the entire experience much less stressful.

Why It's Worth Sorting Out

Many homeowners only discover there's a problem when they decide to sell.

Suddenly, the buyer's lawyer starts asking questions.

The bank may request more information.

Insurance companies may want clarification.

What could have been a straightforward sale becomes far more complicated.

Addressing these issues early often gives you more options and removes uncertainty before it becomes a bigger problem.

Thinking About Buying a Property?

If you're considering purchasing a property with unconsented building work, don't automatically assume it's a bad investment.

Instead, find out exactly what you're dealing with.

Sometimes the issue is relatively straightforward. Other times it requires more work. Either way, understanding the situation before you buy puts you in a much stronger position to make an informed decision.
