Do You Need Building Consent for Renovations in Hawke’s Bay?

Renovating your home is exciting - but building consent confusion is one of the biggest reasons projects get delayed, go over budget, or cause stress for homeowners.

At Refresh Renovations® Hawke’s Bay, one of the most common questions we’re asked is:

‍

“Do I need building consent for this renovation?”

The answer depends on what you’re changing, not just how big the project is. This guide explains when building consent is required in Hawke’s Bay, with specific examples for bathrooms, kitchens, and home extensions.

Why Building Consent Matters in Hawke’s Bay

Building consent exists to ensure renovations:

• Are structurally sound
• Meet the NZ Building Code
• Protect health, safety, and long-term durability

Starting work without the required consent can result in:

• Costly rework
• Delays and fines
• Problems when selling your home
• Insurance issues

That’s why understanding consent before you renovate is critical.

Bathroom Renovations and Building Consent

Bathroom renovations are one of the most misunderstood areas when it comes to consent.

Bathroom Renovations That Usually Do NOT Need Consent

You typically don’t need consent if you are:

• Replacing existing fixtures (toilet, vanity, shower) in the same location
• Updating tiles, linings, or flooring
• Replacing plumbing without altering pipe locations
• Cosmetic upgrades only

Bathroom Renovations That DO Require Consent

You will likely need consent if:

• Plumbing is being moved or altered significantly
• Structural changes are involved (walls, floors, load-bearing elements)
• Waterproofing systems are changed
• You’re adding a new bathroom where one didn’t exist

Because waterproofing and drainage failures can cause serious damage, these projects must meet strict compliance standards.

In addition to structural and waterproofing changes, building consent is also required when adding additional sanitary fixtures to a bathroom.

This is an area that often causes confusion.

Many homeowners assume they can simply add an extra toilet, shower, or vanity to an existing bathroom without consent. However, if you increase the number of sanitary fixtures, building consent is typically required - even if the room itself already exists.

This is because adding fixtures can affect:

• Drainage capacity
• Plumbing design and compliance
• Overall system performance

For example, adding a second toilet to a bathroom where only one existed previously will usually trigger consent requirements.

We assess consent requirements early and manage documentation, inspections, and council coordination for you.

Kitchen Renovations and Building Consent

Most kitchen renovations do not require building consent, but there are important exceptions.

Kitchen Renovations That Usually Don’t Need Consent

• Replacing cabinetry and benchtops
• Upgrading appliances
• Cosmetic updates
• Minor electrical or plumbing work

Kitchen Renovations That May Need Consent

• Removing or altering load-bearing walls
• Structural changes to floors or ceilings
• Major plumbing relocations
• Changes that affect fire or structural safety

Open-plan kitchen renovations often trigger consent requirements when walls are removed - even if the change seems “simple”.

Pro tip: Structural changes nearly always need professional assessment before work begins.

Home Extensions and Additions: Consent Is Almost Always Required

If you’re planning a home extension in Hawke’s Bay, building consent is typically mandatory.

This includes:

• Adding bedrooms or living spaces
• Extending kitchens or bathrooms
• Garage conversions
• Second-storey additions

Consent is required because extensions affect:

• Structural integrity
• Weather-tightness
• Fire safety
• Drainage and services

In some cases, resource consent may also be required, depending on zoning and site rules.

Who Is Responsible for Building Consent?

While homeowners are legally responsible for compliance, managing consent is complex and time-consuming.

At Refresh Renovations® Hawke’s Bay:

• We identify consent requirements early
• Prepare documentation with designers and engineers
• Submit applications to council
• Coordinate inspections
• Ensure final Code Compliance Certification (CCC)

This removes risk and protects your investment.
