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.

Why Class 3 and 9c Buildings Need Specialist Remedial Contractors

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.

Step 1: Verify DBP Registration (The Non-Negotiable)

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:

1. Go to the NSW Fair Trading Building Practitioner Register (service.nsw.gov.au)
2. Search by the contractor's company name, individual name, or registration number
3. Confirm the registration category covers "building practitioner" (not just "design practitioner")
4. Check the registration status shows "Current" — not "Expired", "Suspended", or "Cancelled"
5. Note the registration number for your records

What to watch for:

• A contractor who provides a licence number instead of a DBP registration number. They're different things. A contractor licence (issued under the Home Building Act) is not the same as DBP registration. You need both.
• A contractor who says they're "in the process of registering." If they're not registered today, they cannot perform regulated work on your building after July 1. "In process" isn't compliant.
• A contractor who provides a registration number but it belongs to a different entity. Check the name on the register matches the contracting entity in your agreement.

Step 2: Confirm Professional Indemnity Insurance

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:

• A Certificate of Currency for Professional Indemnity insurance
• Confirm the policy covers remedial building work specifically (some PI policies exclude certain work types)
• Check the policy period extends through the duration of your project — if it expires mid-project, the contractor becomes non-compliant
• Verify the insured party matches the contracting entity

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.

Step 3: Assess Remedial Construction Experience (Not Just Registration)

Registration proves legal eligibility. Experience proves capability. For Class 3 and 9c buildings, you need both.

Questions to ask:

1. How many remedial projects have you completed on Class 3 or 9c buildings? If the answer is zero — they're registered but untested in your building class. That's not automatically disqualifying, but it changes your risk assessment.
2. Can you provide references from aged care facility operators or boarding house owners? A reference from a Class 2 strata committee is useful but not equivalent. The occupancy management, vulnerable resident considerations, and regulatory overlay are different.
3. What remedial work types do you specialise in? "Remedial building work" is broad. It includes concrete cancer repair, waterproofing, facade remediation, structural strengthening, fire safety upgrades, and building envelope work. A contractor specialising in facade remediation may not be the right choice for internal waterproofing — and vice versa. Match the contractor's specialty to your building's needs.
4. Have you worked on occupied buildings where residents couldn't be relocated? This is the critical differentiator for Class 3/9c. Working around elderly residents with dementia, or hostel residents with mental health needs, requires a different site management approach than working on vacant floors of a Class 2 apartment building.
5. Do you have experience with the NSW Planning Portal lodgement process? A contractor who's been operating under the DBP Act since it applied to Class 2 buildings (from July 2021) has five years of Portal experience. A contractor who's newly registered for the July 2026 expansion may be learning the process in real time on your project.

Step 4: Evaluate Planning Portal Competency

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:

• A Construction Issued Regulated Design (CIRD) lodged by a registered design practitioner before work commences
• A building compliance declaration lodged by the building practitioner on completion
• Ongoing records linking the as-built work to the lodged design

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:

• Has the contractor lodged compliance declarations on the Planning Portal before? Ask for portal reference numbers from previous projects.
• Do they have an established relationship with a registered design practitioner who handles the design lodgement?
• Can they explain the lodgement sequence for your specific project scope?

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.

Step 5: Check Documentation Standards

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:

• Detailed scope and methodology before work starts (not a one-line "remedial repairs as discussed")
• A construction program showing staging, duration, and resident impact periods
• Hold-point inspection records during construction (quality verification at critical stages)
• As-built documentation on completion (what was actually done vs. what was specified)
• Warranty documentation with clear terms, duration, and coverage scope
• Compliance declaration lodged on the Planning Portal

A weak contractor provides:

• A lump-sum quote with minimal description
• No program ("we'll start when we start")
• No mid-project documentation
• A verbal assurance that "it'll be fine"
• No Portal lodgement (or lodges late, incorrectly, or not at all)

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.

Step 6: Understand the Difference Between Registration Categories

Not all DBP registrations are equal. The register includes multiple categories:

• Building practitioner — can perform regulated building work (this is what you need for remedial construction)
• Design practitioner — can design regulated building work and lodge designs on the Portal
• Principal design practitioner — coordinates design compliance across disciplines
• Professional engineer — provides engineering design for regulated work

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.

Red Flags When Selecting a Remedial Contractor

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.

The 30-Day Window: What to Do This Week

With one month until the deadline, here's the practical sequence:

If you have work starting in July or August:

1. Verify your contractor's DBP registration today
2. Request their PI insurance certificate
3. Confirm they can lodge on the Planning Portal
4. If any of these checks fail — start procurement for a replacement immediately

If you have work planned for later in 2026:

1. Add DBP registration as a mandatory tender requirement now
2. Build the verification steps into your procurement process
3. Allow extra procurement time — the pool of registered remedial contractors for Class 3/9c is smaller than the general market

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.

NSW Building Commission Data: Why This Matters Now

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.

Frequently Asked Questions

Can a Class 2-experienced remedial contractor work on a Class 3 or 9c building?

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.

What if our current contractor isn't registered and refuses to register?

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.

Is there a list of DBP-registered remedial contractors for Class 3/9c buildings?

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.

How long does the DBP registration process take?

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.

Does the contractor need separate registration for each building class?

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.
