Reading a LIM for Building and Weathertightness Risk

A LIM report is the closest thing property buying has to an official disclosure document, and most people read it wrong. They skim for something alarming, find nothing, and file it as reassurance. But a LIM is not a clean bill of health, it is a summary of what the council happens to know, and reading it well means knowing exactly what to look for and what its silences do and do not mean. For anyone looking at an older Auckland home, and especially a plaster-clad one, here is how to read a LIM like a professional would.

What a LIM actually is

A Land Information Memorandum is a report the council must provide under section 44A of the Local Government Official Information and Meetings Act 1987, summarising the information it holds about a property. Anyone can order one from Auckland Council, and the council must supply it within 10 working days (urgent options are faster). It costs a few hundred dollars, check the council's current fees, which is trivial against the cost of what it can reveal.

An Auckland LIM can include: building, plumbing and resource consents; notices, orders or requisitions affecting the land or buildings; rates, including overdue rates; known natural hazards such as flooding, erosion or subsidence; public and private stormwater and sewerage drains; heritage listings; and information the council has received from other statutory organisations.

The one limitation that changes how you read it

A LIM shows what the council knows. Nothing more. Auckland Council itself is plain about this: its records only include work it knows about, and work done without consent will not be in them. A private repair never notified to the council, an unconsented alteration, a leak history handled quietly between a previous owner and their builder, none of it appears.

This is why a clean LIM is necessary but not sufficient. It rules out the problems the council has on record; it says nothing about the problems nobody told the council about. On a home with leaky-era risk features, the LIM is one leg of a three-legged stool, alongside the property file and a specialist inspection, and it cannot carry the weight alone.

What to look for, item by item

Open consents with no Code Compliance Certificate. This is the single most important check. Every building consent should end in a CCC, and a consent that never got one means work that was never signed off: maybe trivial, maybe not, but always a question that becomes your question the day you settle. On weathertightness-relevant work, cladding, decks, extensions, an open consent is a serious flag.

Reclad or major remediation consents. A consent history showing a reclad is not a red flag, it is often the opposite. It tells you the home had a weathertightness problem and, if the consent has its CCC, that the fix was done under inspection and signed off. A properly documented reclad can make an older plaster home one of the safer buys on the street. What you then want is the detail, which lives in the property file: the scope, the framing repairs, the inspections.

Notices to Fix and other enforcement. Notices, orders and requisitions appear on the LIM, and a Notice to Fix, the council's formal demand to remedy non-compliant work, is exactly the kind of unresolved item that should stop a purchase until it is understood.

Certificates of Acceptance. A CoA is the council's limited, after-the-fact acceptance of work done without consent. Its presence tells you two things: someone built without consent, and the council could only verify what it could still see. On cladding or structural work, treat a CoA as a prompt to investigate, not a substitute for a CCC.

Weathertightness references. Where the council holds information about weathertightness matters, formally notified claims under the old Weathertight Homes scheme, related notices, it can appear in the LIM. But absence is not evidence of absence: not every claim or leak history reached the council's records, so a silent LIM does not mean a dry history.

Hazards and drainage. Flooding, ponding, overland flow and land stability notations matter for a home's moisture exposure, and the drainage information tells you where the water around the site is supposed to go. On a home already carrying envelope risk, a flood-prone notation compounds the question.

The LIM's partner: the property file

The LIM is the summary; the property file is the evidence. It holds the underlying documents, consent applications, approved plans, inspection records, correspondence, and Auckland Council explicitly recommends ordering both, because neither replaces the other. In weathertightness due diligence the property file is where the real answers live: whether a past reclad covered the whole envelope or one elevation, what the inspectors saw with the framing open, what the consented drawings actually show. If the LIM raises a question, the property file is where you take it.

Putting it together on a leaky-era home

For a plaster or monolithic-clad home of the late 1980s to mid 2000s, the sensible sequence is: LIM and property file ordered early, read against the checklist above; a specialist weathertightness inspection on the physical building, since the records cannot see inside the walls; and the two read together. Records clean but the building suspect means the problem was never reported. Records showing a consented, certified reclad means you are mostly verifying the work matches the paper. Records showing open consents, a CoA on cladding, or a Notice to Fix means the price of the property should reflect the cost of resolving them, because that cost transfers to you at settlement. The building side of that assessment, what the records mean for the walls themselves and what putting anything right would involve, is remediation territory, and worth a specialist's read before unconditional, not after.

The full pre-purchase picture for these homes, cladding, era, cavity, inspection, is covered in buying a monolithic-clad house in Auckland.

A LIM will not make the decision for you. Read properly, alongside the property file and a real inspection, it does something more useful: it turns unknown risk into a priced, negotiable, decidable question before you sign, rather than a discovery after.
