Long-Term Maintenance Plans for Waterfront Bodies Corporate

Most apartment buildings on the Wellington waterfront are unit title developments, owned collectively through a body corporate. That means the roof, the cladding, the windows, the lifts and the structure are a shared responsibility, and so is the bill for keeping them in order. The tool for planning that work is the long-term maintenance plan. Near the harbour, where salt, wind and rain push buildings harder than they would be pushed inland, a good plan matters more than usual.

What the law requires

Under the Unit Titles Act 2010, every body corporate must have a long-term maintenance plan. The rules were strengthened by the Unit Titles (Strengthening Body Corporate Governance and Other Matters) Amendment Act 2022, and the changes to long-term maintenance took effect on 9 May 2024.

The core requirements, as set out on the government’s unit titles maintenance guidance, are:

• All bodies corporate need a plan covering at least 10 years.
• Large developments, meaning those with 10 or more principal units, must plan at least 30 years ahead, with detailed costings for the first 10 years.
• Reviews must happen at least every three years, and sooner if something comes to light that could materially affect the plan.
• Professional input: large developments must consult building professionals or other suitably qualified people when preparing and reviewing the plan, unless the body corporate decides otherwise by special resolution.

The plan sits alongside a long-term maintenance fund. A body corporate must set one up unless it decides by special resolution not to, and a decision to opt out has to be revisited each year. The fund does not need to cover every cost in the plan, but the gap between the two is worth watching closely.

The detail is in the Act and its regulations, and the rules can change, so check the current versions on the unit titles site before relying on any summary, this one included.

Why 30 years makes sense

The move from a 10-year horizon to 30 years for larger buildings reflects how buildings actually age. Many of the biggest costs come around only once a generation: replacing a roof, recladding, renewing lifts, replacing joinery, or redoing a balcony membrane. A 10-year plan can show a healthy picture right up until the year a major item falls due, at which point owners face a large special levy with little warning.

The Building Code’s B2 Durability clause gives a useful reference point. It sets minimum durability periods under normal maintenance: not less than 50 years for structure and hidden elements, 15 years for elements such as claddings, and 5 years for easily replaced items such as paint. A plan that runs for 30 years will usually see the 5-year items several times and the 15-year items at least once, so it forces those costs into the open.

What coastal exposure changes

A building over or beside Wellington Harbour sits in the sea spray zone, and that affects nearly every line of the plan.

Shorter cycles. Paint, sealants and coatings on metalwork generally need attention more often near the sea. A plan copied from an inland building will understate them.

Metalwork and fixings. Balustrades, brackets, flashings and fixings corrode faster in salt air. Regular inspection should be in the plan, with replacement allowances that reflect real exposure.

Washing and cleaning. Routine exterior washing is cheap compared with early repainting, and some coating warranties expect it. It belongs in the operating budget and the maintenance schedule.

Wind and water. Wellington’s wind drives rain into joints and junctions that would stay dry elsewhere. Sealant renewal, gutter and outlet clearing, and periodic checks of the building envelope all deserve their own lines. See our note on Wellington wind and weathertightness for more.

Structure over water. Where a building sits on or near a wharf structure, the parts below deck are exposed to tidal splash and immersion. These need specialist inspection and long-range budgeting.

Making the plan useful

A plan is only as good as the information behind it. Some practices that help:

• Base it on inspection, not assumption. A condition survey by suitably qualified people gives the plan a factual starting point.
• Record what was done. Dates of painting, washing, sealant replacement and repairs make the next review far more accurate.
• Show the funding picture. Owners should be able to see the expected costs year by year next to the projected fund balance.
• Revisit after events. A major storm, an earthquake, or a defect discovered during other work are all reasons to review early, as the Act itself contemplates.
• Keep it readable. A plan that owners can understand is more likely to be funded properly.

For buyers and owners

Anyone thinking about buying into a waterfront building should read the long-term maintenance plan and the state of the fund carefully. The questions to ask are simple: does the plan run long enough to cover the big items, does it reflect coastal exposure, and is the fund keeping pace? MBIE’s guidance on building safety and maintenance is a helpful general reference.

Good long-term planning is rarely exciting, but it is what keeps a harbourside building weathertight, safe and pleasant to live in for the decades ahead.
