Navigating the PIM Process for Granny Flats (Minor Residential Units) – How EzyConsents Can Help
Whether it’s for extended family, rental income, or future-proofing a property, minor dwellings can offer real value - but the approval process still needs to be handled carefully.
One of the key early steps for the new Granny Flat Exemption is obtaining a Project Information Memorandum (PIM). While often seen as a simple formality, the PIM plays an important role in setting a project up for success.
What is a PIM and why does it matter?
A PIM is issued by council and provides essential information about your site, including:
Zoning and planning constraints
Natural hazards (flooding, alluvial fans, etc.)
Existing services and infrastructure
Development contributions and council requirements
Relevant District Plan provisions
For granny flats, this step is especially important because while some builds may qualify for building consent exemptions (under Schedule 1A of the Building Act), planning rules still apply. That means you can’t assume a granny flat is automatically permitted just because it’s under 70m².
Where things often go wrong
We regularly see projects run into issues because:
Design work starts before checking planning constraints
Assumptions are made about exemption eligibility
Site limitations (wastewater, hazards, covenants) are picked up too late
PIM applications are submitted with incomplete or unclear information
This often leads to delays, redesign costs, or unnecessary back-and-forth with council.
How EzyConsents adds value
At EzyConsents, we treat the PIM stage as an opportunity to de-risk the project early and set a clear pathway forward.
Our approach typically includes a thorough pre-PIM assessment, strategic PIM lodgement, proactive management of council interactions, and setting up clear next steps for a successful project outcome.
Why this matters for the new exemption
Minor residential unit exemptions have created real opportunities - but also a degree of ambiguity. Council interpretation is still evolving, and requirements can differ depending on the specifics of each site.
Thinking about a granny flat?
If you’re considering adding a minor residential unit, the best place to start is with a clear understanding of what your site can actually accommodate.
EzyConsents provides independent, practical advice and can manage the PIM process from start to finish - making sure your project is set up properly from day one.
