NSW Strata Initial Maintenance Schedule (IMS) Explained: What Developers Must Provide and Why Committees Need It
From April 2026, NSW developers must hand over a standard-form Initial Maintenance Schedule (IMS) with every new strata scheme. Here's what it must contain, what happens if it's missing, and why existing committees should build one now.
Managing a strata scheme well starts long before the first maintenance bill lands. In New South Wales, the Initial Maintenance Schedule (IMS) is a foundational document that tells an owners corporation exactly what has been built, how each asset must be maintained, and what the developer recommends for the building's early life. From April 2026, providing a standard-form IMS becomes a mandatory obligation for developers of new strata schemes — and even committees of older buildings stand to gain by creating one proactively.
This article explains what the Initial Maintenance Schedule IMS NSW requirement actually involves, what it must cover, and the practical steps strata managers and committees should take right now.

What is an Initial Maintenance Schedule (IMS) in NSW strata?
An Initial Maintenance Schedule is a structured document, prepared by or on behalf of a developer, that captures the maintenance requirements of a new strata building from the moment the owners corporation takes over. It acts as a handover knowledge base — translating the builder's and designer's intentions into plain, actionable maintenance tasks for the committee and its managing agent.
The IMS is distinct from, but closely related to, the 10-year capital works fund plan (formerly called the sinking fund forecast) that all strata schemes in NSW must maintain. Where the capital works plan focuses on long-term financial forecasting, the IMS focuses on the *operational* detail: what to do, how often, who should do it, and what warranties or manufacturer requirements apply.

Why is the IMS becoming mandatory in NSW from April 2026?
NSW strata law reform has long recognised that new buildings are often handed to owners corporations with inadequate maintenance documentation. Without clear guidance, committees inadvertently void manufacturer warranties, miss essential safety measure (ESM) obligations, and underfund their capital works plans — creating expensive problems within just a few years.
The reforms, flowing from recommendations to improve the *Strata Schemes Management Act 2015* (NSW), will require developers to provide the IMS in a prescribed standard form before or at the time the initial period ends. The standardised format is designed to make the document consistent and usable across all new schemes, rather than the variable — and sometimes near-useless — documents that have been common practice.
Key reasons the IMS is being mandated:
- Warranty preservation — many defect and product warranties require maintenance to be carried out at specific intervals; missing them can void cover.
- Safety compliance — essential safety measures (fire systems, emergency lighting, exit signs, lifts, etc.) require documented inspection and service regimes.
- Capital works accuracy — a well-documented IMS gives quantity surveyors and strata managers reliable data for 10-year capital works fund planning.
- Reduced disputes — clear handover documentation limits finger-pointing between developers, builders, and owners when things go wrong early.

What must the NSW Initial Maintenance Schedule contain?
While the precise prescribed form will be confirmed by regulation before the April 2026 commencement, the IMS is expected to cover, at minimum, the following categories of information:
1. Asset and system register
A comprehensive list of all common property assets — including building fabric, mechanical, electrical, hydraulic, and fire-safety systems — with make, model, installation date, and relevant warranty periods noted for each.
2. Recommended maintenance tasks and frequencies
For each asset or system, the schedule should specify:
- The nature of the maintenance task (inspection, servicing, testing, cleaning, lubrication, etc.)
- The recommended frequency (monthly, quarterly, annually, every five years, etc.)
- Whether the task must be carried out by a licensed or accredited contractor
3. Warranty and compliance requirements
Any maintenance actions that are required to preserve a manufacturer's warranty or to meet a legislative compliance obligation (such as essential safety measures under the *Environmental Planning and Assessment Act 1979* and associated regulations) must be explicitly flagged so committees understand the consequences of non-compliance.
4. Contractor and product information
Where relevant, the IMS should include details of preferred or nominated service contractors, supplier contacts, and any proprietary systems that require specialist servicing.
5. Defect liability period notes
The document should indicate the period during which the developer remains responsible for defects (typically two years for general defects and six years for major defects under NSW law), so the committee knows what to claim on versus what to fund themselves.

What happens if a developer fails to provide the IMS?
Under the incoming regime, failing to provide the IMS in the prescribed form will expose a developer to regulatory consequences. Committees that do not receive an IMS — or receive one that is clearly deficient — should:
- Document the gap in writing to the developer or their representative immediately after the initial period.
- Seek advice from a strata lawyer or the NSW Fair Trading strata team about their options.
- Commission an independent IMS from a qualified building consultant or facilities manager so the scheme is not left without a maintenance roadmap while any dispute is resolved.

Why should existing strata committees create an IMS proactively?
The mandatory IMS applies to new schemes from April 2026 — but there is no good reason for older buildings to operate without an equivalent document.
Many established owners corporations in NSW are managing assets with no consolidated maintenance register, outdated service contracts, and capital works fund plans that were prepared with incomplete building information. The result is reactive, expensive maintenance and underfunded reserves.
Benefits of a proactive IMS for existing schemes
- Structured planning: A consolidated schedule lets committees and managers plan and budget across financial years rather than responding to failures.
- Contractor accountability: When tasks and frequencies are documented, it is far easier to audit whether service providers are actually delivering what is contracted.
- Better capital works fund forecasting: Quantity surveyors and strata managers can produce more accurate 10-year plans when they have a clear picture of asset condition and expected maintenance cycles.
- Smoother committee transitions: When committee members change, an up-to-date IMS means institutional knowledge is not lost — the incoming member can immediately understand what is managed, by whom, and when.
- Insurance and liability protection: Demonstrating documented maintenance is a significant asset if an insurer queries whether a loss was caused by neglect.
How to create an IMS for an existing building
- Commission a building audit — a qualified building consultant or facilities manager inspects all common property and documents every major asset.
- Collate existing records — gather service contracts, compliance certificates, product manuals, and previous capital works fund reports.
- Map tasks to assets — for each asset, assign maintenance tasks, frequencies, responsible parties, and cost estimates.
- Integrate with your strata management platform — a digital maintenance schedule linked to your work-order system ensures tasks are actually triggered and tracked, not just documented on paper.
- Review annually — the IMS is a living document; it should be updated whenever assets are replaced, upgraded, or re-specified.
Orveya's facilities management tools are designed to help strata managers and committees maintain exactly this kind of structured, auditable asset and maintenance register — linking schedules to work orders and financial planning in one place.

What is the relationship between the IMS and the capital works fund plan?
The IMS and the capital works fund plan are complementary, not interchangeable. Think of the IMS as the operational layer (what maintenance must happen and when) and the capital works fund plan as the financial layer (how much money the scheme must set aside for major repairs and replacements over 10 years).
A good IMS feeds directly into a more accurate capital works fund plan because it:
- Clarifies asset lifespans and replacement cycles
- Identifies maintenance work that, if deferred, accelerates asset deterioration
- Provides the quantity surveyor with verified asset data rather than estimates
NSW strata legislation requires the capital works fund plan to be reviewed at least every five years. Each review is an ideal trigger to also update the IMS.

Frequently asked questions
When does the mandatory IMS requirement start in NSW?
The requirement for developers to provide a standard-form Initial Maintenance Schedule applies to new strata schemes from April 2026. Schemes registered before that date are not retrospectively required to have an IMS, but are strongly encouraged to create one.
Who is responsible for preparing the IMS — the developer or the builder?
In NSW, the obligation falls on the developer (the person who registered the strata plan). In practice, developers typically commission the IMS from the builder, a building consultant, or the project's certifier, but legal responsibility for providing it rests with the developer.
Does the IMS replace the 10-year capital works fund plan?
No. The IMS and the capital works fund plan serve different purposes. The IMS documents maintenance tasks and frequencies at an operational level; the capital works fund plan is a long-term financial forecast for major repairs and replacements. Both documents are required, and a well-prepared IMS significantly improves the accuracy of the capital works fund plan.
What should a committee do if the IMS they receive is incomplete or unclear?
Write to the developer in writing requesting a compliant document. If the developer does not respond, seek advice from a strata solicitor or contact NSW Fair Trading. In the interim, commission an independent building consultant to prepare an equivalent schedule so the scheme's maintenance program is not delayed.
Can the IMS be used to manage essential safety measure (ESM) compliance?
Yes — and it should be. The IMS is an ideal place to document all ESM obligations (fire systems, emergency lighting, exit signs, mechanical ventilation, etc.) alongside their required inspection and testing frequencies and the responsible licensed contractors. This helps ensure ESM annual fire safety statements are supported by up-to-date service records.
