Consent, Licensing & LBP Obligations

Welcome to the RANZ Compliance Wizard

This tool helps Roofers, LBPs, and Homeowners determine their obligations under the Building Act 2004 and the LBP Rules.

Throughout this tool, you will see Case Law Alerts based on real, upheld complaints from the Building Practitioners Board (BPB) and MBIE Determinations.

Phase 1: What is your situation?

Step 1: The Job Scope

Design Changes = No Exemption [OPEN PDF]
In Newton [2023], a roofer replaced a dormer but removed parapets. The Board ruled this was not "like-for-like". If you change the design, Schedule 1 does not apply.

What is the nature of the work?

Step 1b: Technical Risks & Pitch

New Determinations Loaded
Includes specific logic for Pitch (Det 2018/021), Trusses (Det 2023/008), Shipping Containers (Det 2019/057) and Attic Storage (Det 2023/036).

A. Roof Pitch (Check 2016/016)

B. High Risk Scenarios (Select ALL that apply):

Step 1c: Age & Durability

The 15-Year Rule
Exemption is EXCLUDED if the component failed before its 15-year durability requirement (Clause B2).

How old is the current roof?

Step 2: Consent Status

Duty to Check [OPEN PDF]
In Corbett-Pearson [2024], a roofer assumed a consent was in place but didn't check. The Board ruled the LBP is in the best position to stop unconsented work.

Has a Consent been issued?

Execution: Building Type

Restricted Building Work
RBW rules specifically apply to residential buildings.

Is this a Residential building?

Execution: Making Changes

"My way is better" Trap [OPEN PDF]
In Langdon [2025], a roofer was fined for using a "better" method without approval. In Smith [2023], product substitution was a key issue.

Are you deviating from the Plans, altering an existing configuration, or substituting products?

Execution: Workmanship Details

Determination Workmanship Checks
Recent MBIE determinations (2024-2025) have set strict rules for finishing details.

Are you performing any of the following tasks?

Execution: Substrate & Structure

Substrate Responsibility [OPEN PDF]
In Woolhouse [2024], relying on the builder's incorrect set-out was no defence. Do not cover up non-compliant work.

Have you checked the substrate (purlins/ply/underlay) provided by previous trades?

Execution: Licence Class

Scope of Licence [OPEN PDF]
In Casha [2025], a roofer was fined for doing work outside his specific licence class (Membrane vs Metal).

Do you hold the specific Licence Class for the material you are installing?

Execution: Supervision

Remote Supervision [OPEN PDF]
In Horrack [2024], the Board ruled "Remote supervision does not mean NO supervision".

How are you supervising this job?

Execution: Completion

Withholding Paperwork [OPEN PDF]
In Moyes [2025], an LBP was fined for withholding a Record of Work due to unpaid invoices.

What is the job status?
