Outdoor Fireplace Compliance: What You Need to Know

Do I need consent for an outdoor fireplace? Do I need a permit to light one? Is it even legal to put one in my backyard? These questions get asked in a dozen different ways, but they all circle the same thing: what does it take to install and use an outdoor fireplace without running into problems later on?

Compliance in New Zealand comes down to three separate sets of rules, and they all apply at the same time. Once you can see how the pieces fit together, it's fairly straightforward. Below is the high-level overview, with links to our detailed guides if you want the full story on any one part.

Layer One: Building Consent

This is where most people start. When someone searches "outdoor fireplace consent NZ," they usually want to know whether a building consent is required at all. For most freestanding outdoor fireplaces, it isn't, as long as the structure:

• Sits on the ground and isn't attached to a building
• Isn't covered by a roof or wall
• Stands no taller than 2.5 metres
• Has a cooking surface under 1 square metre
• Sits at least 1 metre from any boundary or building

Plenty of fireplaces sit right on the edge of those limits. Many of ours stand at around 2.6 metres, which lands them in a grey area where some councils ask for consent and others grant an exemption. For anything taller, larger, or attached to your house, a fireplace consent becomes far more likely, and your boundary distances start to matter too. We cover those in our guide to installing a fireplace near your boundary.

Consents are usually the first hurdle to clear, and where most of the detail sits. Read our full guide to consents for an outdoor fireplace for the step-by-step on exemptions, paperwork, and what your council will want to see. The team at Trendz are always happy to assist you with whether you will need to go through this process or not.

Layer Two: Regional Council Rules

Even when your fireplace is exempt from building consent, your regional council may still have a say, mostly about smoke and air quality. This is where the rules vary the most from one part of the country to another:

• Canterbury runs Clean Air Zones with seasonal limits on outdoor burning
• Auckland restricts open fires in urban areas under its fire safety bylaw
• Otago has air zones with their own boundary distances

The common thread across almost all of them is that your fire shouldn't create a smoke nuisance for your neighbours, whatever the season. We've pulled the main regions together in our regional council guide, and gone deeper on the Canterbury rules in our Clean Air Zone article. It is worth noting that you can have an outdoor fireplace anywhere in New Zealand so long as it is being used as a ‘wood-fired BBQ’

Layer Three: Fire and Emergency New Zealand

The third layer has less to do with how your fireplace is built and everything to do with whether you can light it on a given day. Fire and Emergency New Zealand sets fire seasons that shift with conditions:

• Open: fires may be lit without restriction
• Restricted: a fire permit is usually required
• Prohibited: most open-air fires are banned

Before lighting up, check your current fire season at checkitsalright.nz. One point that trips people up: even when your fireplace is built 1 metre from the boundary under the building rules, a fire permit can require it to sit 3 metres away before you're allowed to light it.

A permanent outdoor fireplace can often be used year-round, even in a prohibited season, provided it meets specific safety conditions. We walk through those in our guide to using a fireplace during a fire ban.

How a Cooking Grill Changes the Rules

This point applies across both the council and Fire and Emergency layers, so it gets its own section. In several regions where open recreational fires are restricted, an outdoor fireplace fitted with a cooking grill is classed as an outdoor cooking structure instead, much like a barbecue or pizza oven.

That reclassification can be the difference between a fire you can use year-round and one you can't, which is why many of our designs include a cooking grill as an option.

Getting It Right

None of these three layers is especially hard on its own. They stack, though: ticking the building box doesn't cover you on air quality, and a fire permit doesn't replace a consent. All three need to line up before you can relax and enjoy the fire.

That's the part we're happy to take off your hands. Trendz has worked with councils across the country since 2006, and we regularly assist our clients with fireplace consent applications and exemption certificates for our customers. If you're unsure where your outdoor fireplace lands, our team can talk you through it and point you toward a design that fits your site and your region.

Once the compliance side is sorted, the fun part is choosing the fireplace itself. Download our brochure to explore the full range and find the design that suits your space.
