The plain-English difference between the two consents — building consent for how you build, resource consent for what the rules allow, and when roofing touches each.
NZ has two different consents that can apply to building projects, and the difference is genuinely useful to understand: building consent is about HOW you build (does the work meet the Building Code — structure, weathertightness, safety), while resource consent is about WHAT the planning rules allow (does the activity fit the district plan — height, boundaries, character, land use). A project can need one, both, or neither.
For roofing, the usual relationship is with building consent (or exempt maintenance), but some situations touch resource consent. This article explains the distinction in plain English — general information; the council confirms what your work needs.
This is a plain-English introduction, not specific advice. Auckland Council is the authority on both consents and what applies to your specific property and work.
What is the difference between resource and building consent?
Direct answer, in plain English: building consent is about how you build, resource consent is about what the planning rules allow. They address different questions: building consent checks that building work meets the Building Code — structural integrity, weathertightness, safety, the "is it built properly and safely" question, the consent our exempt-work guide discusses (with some work exempt); and resource consent checks that an activity fits the district plan's rules.
Height, boundaries, character, land use, the "does the planning framework allow this here" question, governed by planning rules rather than the Building Code. A project can need building consent only, resource consent only, both, or neither, depending on what it involves. For roofing specifically, the usual relationship is with building consent (or it is exempt maintenance), while resource consent comes in only where roofing touches planning matters (the next section). Understanding that the two consents answer different questions.
How you build versus what is allowed — is the key insight; the council confirms which your specific work needs. New build and major work connects to the building expertise at our parent brand My Homes Construct.
In short
Building consent is about HOW you build (meeting the Building Code); resource consent is about WHAT the planning rules allow (district plan — height, boundaries, character). A project can need one, both, or neither. Roofing usually relates to building consent or is exempt, touching resource consent only in some situations (height, heritage). The council confirms what your work needs.
When roofing touches resource consent
Most roofing does not involve resource consent, but some situations do, and knowing them helps: raising roof height — work that increases roof height beyond what the planning rules allow (for example on an extension, the height-to-boundary rules our companion guide covers) can trigger resource consent, a planning matter distinct from the Building Code; special-character and heritage areas — work in special-character areas where the look is controlled, where visible roofing changes can involve resource consent or planning requirements, the heritage rules our guide describes.
Other district-plan matters — various planning considerations (overlays, controls) that specific properties carry; and the distinction holding — these being planning questions (what the rules allow), separate from whether the work is built to Code (building consent). So a re-roof might need building consent (or be exempt) for the building-work aspect, and separately need resource consent if it, say, raises height beyond the rules or is in a controlled-character area.
Because these depend entirely on your property and proposed work, whether resource consent applies is a council question — confirmed with Auckland Council, and where planning is involved, helped by a designer or planner. The honest framing: roofing usually means building consent or exempt maintenance, with resource consent the exception for planning-affecting work.
Why the distinction matters — and checking with the council
Understanding the two-consent distinction has practical value: knowing what to ask — recognising that "is it built properly" (building consent) and "is it allowed here" (resource consent) are different questions helps you ask the right things about your project; both can apply — appreciating that a project can need both consents (assessed separately) prevents the assumption that one covers everything, important for extensions and significant work; roofing's usual position.
Knowing that roofing usually relates to building consent or is exempt, with resource consent the exception, sets sensible expectations; and the council as authority — because what your specific work needs depends on your property, the proposed work, and current rules, Auckland Council is the authority that confirms it, with designers and planners helping on planning-affecting projects.
The recurring advice across our regulation guides applies here too: for any significant or potentially planning-affecting roofing work, check with the council early, so you know which consents (if any) apply before committing. The honest bottom line: two consents, two different questions (how you build, what is allowed), roofing usually building-consent-related or exempt — and the council the authority for your specific project. This article is a plain-English introduction, not specific consent advice.
Practical takeaways
Building consent is about how you build (the Building Code); resource consent is about what the planning rules allow (the district plan). A project can need one, both, or neither. Roofing usually relates to building consent or is exempt maintenance, touching resource consent mainly where it affects height, heritage character, or other planning matters. For your specific work, Auckland Council confirms which consents apply. This article is a plain-English introduction only, not specific advice — check with the council early on significant work.

Frequently asked questions
What is the difference between the two consents?
Building consent is about how you build (the Building Code); resource consent is about what the planning rules allow (the district plan).
Does roofing usually need resource consent?
Usually not — most roofing relates to building consent or is exempt. Resource consent applies mainly to planning-affecting work.
When might roofing trigger resource consent?
Raising height beyond planning limits, work in controlled-character areas, and other district-plan matters — check with the council.
Can a project need both?
Yes — building consent (how it is built) and resource consent (what is allowed) can both apply, assessed separately.
Who tells me which I need?
Auckland Council — the authority on both. This article is a plain-English introduction only.
