From July 2026, Class 3 and 9c buildings need DBP-registered contractors for remedial work. Here's how to verify credentials, assess experience, and choose the right builder before the deadline.
From 1 July 2026, every remedial building work project on a Class 3 or Class 9c building in NSW must be performed by a registered building practitioner under the Design and Building Practitioners Act. That deadline is now 30 days away.
If you manage a boarding house, hostel, student accommodation block, hotel, aged care facility, or nursing home — and you have remedial work planned, budgeted, or overdue — the question has shifted from "what's changing" to "who do I hire."
We've already published what the DBP Act expansion means for your building and our 5-week compliance checklist for preparing before the deadline. This post goes deeper on one specific step: how to identify, verify, and choose the right remedial contractor for your building under the new compliance regime.
This matters because not all registered building practitioners are the same. Registration is a minimum threshold — it tells you a contractor meets the legal requirement to do regulated work. It doesn't tell you they're experienced with remedial construction, familiar with your building class, or capable of managing the compliance documentation your project requires.
Class 3 buildings (boarding houses, hostels, student accommodation, hotels with shared facilities) and Class 9c buildings (aged care facilities, nursing homes) have specific characteristics that affect remedial work:
Continuous occupancy. Unlike Class 2 apartments where you can stage work around a few vacant units, aged care facilities and boarding houses have residents who cannot easily relocate. Remedial work must be planned around vulnerable occupants who may have mobility issues, medical equipment dependencies, or cognitive impairments.
Regulatory overlay. Class 9c buildings operate under the Aged Care Quality Standards, which impose additional requirements around building condition, safety, and resident welfare. A contractor unfamiliar with aged care environments may trigger compliance issues with the Aged Care Quality and Safety Commission — not just Fair Trading.
Fire safety integration. Both building classes have heightened fire safety requirements due to sleeping accommodation for vulnerable populations. Remedial work on facades, balconies, or building services often intersects with fire safety systems. A contractor who treats the remedial scope in isolation — without understanding the fire safety implications — creates risk.
Heritage and character buildings. Many Class 3 boarding houses in Sydney are pre-war or early post-war buildings with heritage considerations. Remedial work on these buildings requires understanding of traditional construction methods, heritage-sympathetic repair techniques, and sometimes Heritage NSW approvals.
A general builder with DBP registration can legally do the work. A specialist remedial contractor with Class 3/9c experience can do it without disrupting residents, triggering aged care compliance issues, or missing the integration points with fire safety and heritage.
Before anything else, confirm the contractor is registered. This is binary — they're on the NSW Fair Trading register or they're not.
How to verify:
What to watch for:
From 1 July 2026, PI insurance becomes mandatory for all registered building practitioners performing regulated work. This was previously an exemption — it's now a hard requirement.
What to request:
Why this matters for Class 3/9c:
Aged care facilities and boarding houses serve vulnerable populations. If remedial work fails — a waterproofing failure causes a slip injury, a structural repair doesn't hold, a facade panel detaches — the consequences are potentially catastrophic. PI insurance protects the building owner, but more importantly, it signals a contractor who operates at a professional standard that insurers are willing to underwrite.
A contractor who can't obtain PI insurance is telling you something about their risk profile. Don't ignore that signal.
Registration proves legal eligibility. Experience proves capability. For Class 3 and 9c buildings, you need both.
Questions to ask:
The DBP Act isn't just about who does the work — it's about documenting the work through the NSW Planning Portal. Every regulated remedial project requires:
For your Class 3/9c building, this means the contractor must coordinate with a design practitioner (typically a structural or building services engineer) who is also registered and able to lodge on the Portal.
What to verify:
A contractor who fumbles these questions hasn't internalised the compliance framework. That doesn't mean they can't do the physical work — but it means you'll be managing the compliance process yourself, or discovering gaps after the work is complete.
Compliant remedial work produces documentation. Under the DBP Act, that documentation has regulatory significance — it's your evidence trail if questions arise later.
A strong remedial contractor provides:
A weak contractor provides:
For Class 9c aged care buildings, documentation standards intersect with Aged Care Quality Standard 5 (Living Environment). An aged care assessor reviewing your building's maintenance records expects to see structured documentation of remedial work — not a stack of undated invoices.
Not all DBP registrations are equal. The register includes multiple categories:
Your remedial project needs at minimum a building practitioner (the contractor) and a design practitioner (the engineer who specifies the work). These are usually different entities — the contractor doesn't design their own scope.
Some larger remedial contractors have both registrations in-house (a registered building practitioner who is also a registered design practitioner). This can streamline the lodgement process but doesn't eliminate the need for independent design verification — particularly where the remedial specification was prepared by a consulting engineer retained by the building owner.
After years of operating in the regulated remedial construction market, these are the patterns that signal a contractor isn't genuinely ready for post-July-1 work on Class 3/9c buildings:
"We'll sort the registration before we start." Registration takes weeks to months. If they're not registered today — 30 days before the deadline — they're unlikely to be registered by your project start date. Don't gamble on a pending application.
No evidence of PI insurance. If they can't produce a Certificate of Currency within 24 hours of your request, they either don't have it or it's lapsed. Either way, they're not compliant.
No experience with occupied buildings. A contractor whose entire portfolio is new construction or vacant refurbishments will struggle with the constraints of an occupied aged care facility. The physical work might be identical — but the site management, noise control, dust mitigation, access scheduling, and resident communication are completely different.
Unfamiliar with the Planning Portal. If they've never lodged a compliance declaration, your project will be their learning experience. That's not inherently disqualifying — but price it into your risk assessment and ensure they have support.
Can't explain their quality assurance process. Remedial work on regulated buildings requires documented hold-point inspections, material certifications, and methodology records. A contractor who doesn't have a quality system in place will struggle to produce the documentation the Act requires.
Quote significantly below all others. In the context of DBP-compliant work, a dramatically cheaper quote usually means the contractor hasn't priced the compliance overhead — documentation, Portal lodgement, quality records, PI insurance cost passed through. These are real costs. A quote that ignores them isn't cheaper — it's incomplete. For detailed guidance on comparing quotes, see our guide on how to get accurate quotes for remedial work under the new strata rules.
With one month until the deadline, here's the practical sequence:
If you have work starting in July or August:
If you have work planned for later in 2026:
If you're unsure whether your building needs remedial work:
Commission a building investigation and reporting assessment. The investigation identifies what work is needed, how urgently, and provides the specification that contractors quote against. With the DBP deadline approaching, having a clear scope ready means you can procure quickly from compliant contractors rather than scrambling later.
The urgency isn't theoretical. The NSW Building Commission's 2023 research found that 53% of surveyed strata buildings in NSW have serious defects in common property — up from 39% in 2021. Waterproofing failures (42%) and fire safety issues (24%) are the most prevalent.
For Class 3 and 9c buildings, this defect prevalence means remedial work isn't optional or deferrable — it's coming. The question is whether it happens under the regulated framework (with registered practitioners, documented designs, and PI insurance) or outside it (with the legal and safety consequences that follow).
The 53% figure also means the market for registered remedial contractors is about to tighten significantly. Every building in that statistic needs compliant contractors after July 1. Early procurement is a competitive advantage — not just a compliance best-practice.
We've been delivering remedial building work under the DBP Act since it first applied to Class 2 buildings in 2021. Our team holds current building practitioner registration, maintains PI insurance year-round, and has lodged compliance declarations on the NSW Planning Portal across hundreds of projects.
For Class 3 and 9c buildings, we bring specific experience with occupied-building remedial work — staging around vulnerable residents, managing dust and noise in sensitive environments, coordinating with facility managers on access scheduling, and documenting everything to a standard that satisfies both Fair Trading and aged care regulators.
Our registered remedial building services cover concrete repair, waterproofing, facade remediation, structural strengthening, and fire safety upgrades — the full scope of regulated remedial work on Class 3 and 9c buildings.

Yes — DBP registration covers all regulated building classes. A contractor experienced with Class 2 buildings is legally eligible and likely operationally capable. The key difference is occupancy management: Class 3/9c buildings typically have residents who can't relocate. Confirm they have experience working in occupied environments with vulnerable populations.
You need a new contractor for any work starting after July 1. Registration is not optional for regulated remedial work. Use the verification steps above to find a replacement. Don't delay — the pool of available registered contractors will shrink as demand increases near the deadline.
The NSW Fair Trading Building Practitioner Register lists all registered practitioners by category. There's no separate filter for "Class 3/9c experience" — you'll need to verify that through direct inquiry. Industry bodies like the Master Builders Association may maintain referral lists, but always verify registration independently.
Typically 4–8 weeks from application to approval, depending on documentation completeness and current processing volumes. A contractor applying today (1 June) is unlikely to be registered by 1 July. This is why verification now is critical — if your contractor isn't already registered, you need to act immediately.
No. DBP registration covers regulated building work across all applicable classes. A contractor registered for Class 2 work is automatically eligible for Class 3 and 9c work from July 1 — no additional registration required. However, experience with the specific building class remains important even if registration isn't class-specific.
Send photos, the engineer's report, or just the symptoms — whatever you've got. A registered builder reads it and calls you back. No call centre, no obligation.
