Design and Building Practitioners Regulation 2021

The Regulation’s reach is deliberately broad but targeted.

Primary regulated persons

• Design practitioners (Sch 1, Pt 2 Div 1): architects (with low-, medium- and unrestricted classes post-2022 amendments), building designers, civil, structural, mechanical, electrical, geotechnical, fire-safety and façade engineers, drainage designers, fire-systems specialists (detection, hydrant/hose reel, sprinkler, mechanical smoke control) and vertical-transportation designers.
• Principal design practitioners (Sch 1, Pt 2 Div 2): the lead coordinator who must hold a general or body-corporate class.
• Building practitioners (Sch 1, Pt 2 Div 3): body corporates, their nominees (low-rise, medium-rise and unrestricted) and individuals holding general, low-rise or medium-rise classes. A body corporate may only act through a nominated registered individual (cl 36(4)).
• Professional engineers (Sch 1, Pt 2 Div 4): civil, structural, mechanical, electrical, geotechnical and fire-safety engineers. Body corporates cannot be registered in these classes (cl 31).

Supporting obligations

• Recognised engineering bodies (Part 5) that operate registration schemes must satisfy independence, audit, insurance, transition-strategy and annual-declaration requirements (cl 52D–52G).
• Developers, owners corporations, principal certifiers and councils are indirectly affected because they cannot obtain or issue certificates without the required declarations (cl 29–30, Act s 27).
• Insurers providing professional indemnity cover must meet the adequacy tests in Part 6; the Secretary may request claims data (cl 83).

Exclusions and transitional classes

Class 1 dwellings, pure class 5/6/7/8/9a/9b commercial buildings, and most exempt development are outside the scheme (cl 12, 13). Temporary accommodation facilities forming <10 % of gross floor area in a mixed class 9a/9b building are also excluded. Projects commenced before key dates (1 July 2021, 3 July 2023) benefit from grandfathering or certification pathways (cl 28G–28J, 94–97B). Sydney Metro and over-station enabling work have bespoke exclusions (cl 88B).

The net result is that any person or firm wishing to design, certify or construct the residential and aged-care components of the NSW building industry must either hold the appropriate registration or engage someone who does. Failure to do so halts the regulatory pipeline at the construction-certificate and occupation-certificate stages.

Duties

• Designers: prepare regulated designs containing necessary detail (cl 3A), include performance-solution reports (cl 5), fire-penetration details (cl 6), vertical-transportation registration numbers where required (cl 7), integrate other designs “as far as reasonably practicable” (cl 8), and provide comprehensive compliance declarations (cl 9).
• Principal designers: coordinate declarations, provide principal compliance declarations before nominated dates (cl 21), and ensure all designs are covered.
• Builders: give 14 days’ notice of commencement and of intended building compliance declaration to the principal designer (cl 23, 24), lodge designs and declarations before work starts and after variations (cl 16, 17), record variations in a variation statement that lists BCA compliance measures (cl 27), provide access to variation documents (cl 28), and supply building compliance declarations before occupation certificates or within 90 days after (cl 18, 26).
• All registered practitioners: comply with the code of practice (Sch 4), maintain CPD (Sch 3), keep 10-year records (cl 84–88), hold appropriate insurance (Part 6), notify the Secretary of insurance lapse, disciplinary proceedings or changes in nominees/employees (cl 46), and surrender certificates when conditions change (cl 36(1)).
• Recognised engineering bodies: maintain independence, publish registers, audit CPD, hold insurance, provide annual declarations and transition strategies (cl 52D–52G, 60–61).

Rights

• Registered practitioners may authorise another appropriate practitioner to lodge documents on their behalf (cl 16(2), 17(3)).
• Building practitioners may rely on a principal compliance declaration that omits certain matters if provided early (cl 10).
• Applicants for registration have a deemed-refusal right after 28 days (cl 32) and appeal rights under the Act.
• Professional engineers recognised under a professional standards scheme or by a recognised engineering body may satisfy insurance and CPD through those schemes rather than the default Regulation requirements (cl 70, Sch 3 cl 5).
• The Secretary may grant registration despite Schedule 2 if equivalence is shown (cl 3) or waive/refund fees in cases of hardship or special circumstances (cl 93A).

The Regulation creates a mix of strict-liability and fault-based offences. Maximum penalties are consistently 200 penalty units for corporations and 100 for individuals for lodgment, notice and registration offences (cl 16(1), 17(1), 20, 23, 24, 28B–28D, 84(6)). The code of practice (enforceable under Act s 56) carries 5,000/9,900 penalty units for individuals/corporations for serious breaches such as accepting improper benefits or disclosing confidential information.

Penalty notices (Sch 5) allow on-the-spot fines: $1,650/$3,300 for most lodgment failures, $5,500/$16,500 for unregistered work, and lower amounts for insurance and notification breaches. Authorised officers include council officers and EPA investigation officers (cl 90–91).

The Secretary may suspend or cancel registration on grounds including unsuitability, breach of conditions, loss of insurance, or public-interest grounds (cl 43, 52B, 53). Disciplinary action may be taken for misleading the Secretary, partial declarations, or failure to comply with directions (cl 44). Information-sharing powers with councils, certifiers, insurers and engineering bodies facilitate enforcement (cl 92).

Principal certifiers are prohibited from issuing certificates unless declarations have been provided (Act s 26, Reg cl 29–30). This administrative sanction is often more immediate than prosecution.

The Regulation is expressly linked to the Environmental Planning and Assessment Act 1979 (EP&A Act). Construction certificates and occupation certificates cannot issue without the required declarations (cl 29–30). Development control orders and council orders under the Local Government Act 1993 interact with the exclusion provisions (cl 13(1)(c)–(d), (2)).

The Home Building Act 1989 supplies the qualification pathway for many building-practitioner classes (Sch 2 cl 24–25D) and supplies the “general building work” trigger for body-corporate registration (cl 26). Residential building work exclusions are mirrored (cl 13(1)(h)).

The Work Health and Safety Act 2011 and Work Health and Safety Regulation 2017 govern vertical-transportation product registration and designer duties (cl 7, 9(e)). AS 1735 is incorporated by reference.

The Building and Development Certifiers Act 2018 accreditation for fire-safety practitioners provided an alternative pathway until 2023 (cl 95).

Commonwealth legislation is engaged through the BCA (adopted by reference) and the Australian Consumer Law (referenced in the definition of liability in cl 63).

Information-sharing provisions (cl 92) override privacy constraints where reasonably necessary for regulatory functions. The Interpretation Act 1987 supplies general definitions (cl 3 note).

The Regulation has been amended more than a dozen times since 1 July 2021. Key changes include:

• 2022 (62): Introduced ground-anchor requirements (Div 3A, cl 28A–28D) after collapses and injuries associated with temporary anchors on neighbouring land. The changes mandate installation-right documents, destressing evidence and removal evidence to protect adjoining owners.
• 2022 (332) & 2023 (65): Refined classes of registration, created low-rise and medium-rise sub-classes for architects and builders, and extended alternative pathways for fire-systems designers and engineers until 31 December 2023 (cl 97A–97B). These responded to industry feedback that rigid qualification barriers were excluding competent practitioners.
• 2022 (783): Added Sydney Metro carve-outs (Part 7A) to avoid duplicative regulation on major infrastructure projects while preserving over-station enabling work controls.
• 2023 (65): Introduced class 3/9c exemptions for work commenced before 3 July 2023 or designs prepared before that date (cl 28E–28J), recognising that many projects were already in flight when the full scheme commenced. Also tightened building-practitioner insurance exemptions until 30 June 2026 (cl 106).
• 2024 (5) & 2025 (276): Updated definitions of “construction issued regulated design”, added vertical-transportation building-element rules, and extended the building-practitioner insurance exemption.

Each amendment reflects a pattern: initial over-reach corrected by targeted exemptions and sub-classes, followed by infrastructure-specific and safety-specific enhancements (anchors, Metro) driven by incident data and stakeholder consultation.

Because the scheme is relatively new, reported case law remains limited. However, several controversies have emerged.

First, the breadth of “regulated design” has produced disputes about whether incidental structural detailing or performance-solution reports fall inside or outside the declaration obligation. Certifiers have refused occupation certificates where a design practitioner argues that a particular element is not “regulated”.

Second, the interaction with the Home Building Act 1989 has caused confusion for builders who hold contractor licences but not the new DBP registration. The Regulation’s pathway 1 and pathway 2 distinctions (Sch 2) were intended to ease transition but have generated administrative appeals to the Civil and Administrative Tribunal about whether a supervisor certificate automatically satisfies the “recent relevant practical experience” test.

Third, the ground-anchor provisions (cl 28B–28D) have been criticised for imposing evidentiary burdens on builders that duplicate Roads Act consents or easement negotiations. Adjoining owners have used the public lodgment requirement to challenge anchor locations before work commences.

Fourth, the deemed-registration provisions during the 2021–22 transitional period (cl 99–103) led to a number of cancellations when the Secretary later formed the view that applicants had incorrectly self-assessed suitability (cl 101). Affected practitioners argued that the 28-day deemed-refusal clock (cl 32) should have protected them; the Secretary’s position is that the power to cancel on suitability grounds survives.

No superior-court decisions have yet settled the precise scope of “as far as reasonably practicable” integration (cl 8) or the evidentiary value of a variation statement (cl 27) in subsequent defect litigation. These issues are expected to surface in NCAT or Supreme Court proceedings under the Act’s statutory duty of care (Act s 37).

Most practitioners do not realise that:

• A design that varies a performance solution after work has commenced still requires a fresh design compliance declaration and lodgment within one day (cl 17(1)(c)–(d)). The variation-statement route (cl 27) is available only for non-building-element, non-performance-solution variations.
• The 10-year record-keeping obligation runs from the date of completion of building work under the EP&A Act s 6.20(2), not from the date the practitioner last touched the project. Practitioners who leave a firm can remain personally liable for record production years later (cl 84(5)).
• Insurance policies that contain aggregate limits or “claims-made-and-notified” wording can fail the adequacy test in cl 77 if the practitioner has not stress-tested the limit against realistic claim volumes (cl 77(2)(d)). The Secretary can request claims history (cl 83).
• A principal design practitioner appointed under the contract is not automatically the “registered principal design practitioner” for the purposes of cl 21 and 23–24. The appointment must be notified to the Secretary and the practitioner must hold the correct class.
• The exemption for class 3 or 9c buildings that contain no class 2 part expires on 1 July 2026 (cl 13(3A)). Projects currently relying on that carve-out will lose it unless they complete by that date.
• Lodgment “in the approved way” is not satisfied by email or hard copy; the NSW planning portal is mandatory unless technical inability is proven (cl 19A(1A), definition of “approved way”).
• A registered engineer who relies on a professional standards scheme for insurance must still notify the Secretary within 7 days if that scheme lapses or the engineer ceases to be covered (cl 46(e), (g)).
• The code of practice (Sch 4) is enforceable by disciplinary action even if no specific Regulation clause is breached. Accepting a bottle of wine from a supplier on a project can constitute an “improper benefit” (Sch 4 cl 6(3), 15(3)).

These traps have already produced disciplinary notices and refused occupation certificates.

Practical compliance framework

1. Pre-engagement
   Confirm the building classification. If any part is class 2, 3 (non-temporary) or 9c, the full scheme applies. Identify every regulated design element (structural, fire, hydraulic, vertical transport, façade, etc.) and ensure each will be prepared by a practitioner whose class matches the work (Sch 1).

2. Registration and insurance
   Maintain current registration in the correct class. For body corporates, ensure at least one employee (or nominee) holds the requisite individual registration and that the insurance policy extends to all historical and future liability of that individual while employed (cl 68). Conduct the annual adequacy assessment required by cl 77–78 and retain the written record.

3. Design phase

   • Prepare designs to the level required by cl 3A (dimensions, materials, location of elements).
   • For performance solutions, produce a report complying with BCA A2G2 and cl 5.
   • For fire-resisting elements, explicitly address penetrations (cl 6).
   • Obtain or prepare design compliance declarations containing all matters in cl 9.
   • Integrate other designs “as far as reasonably practicable” (cl 8).
   • Lodge via the portal before any construction certificate is issued (cl 16).

4. Principal designer coordination
   Appoint a registered principal design practitioner early. Provide the 14-day notices required by cl 23 and 24. Ensure the principal compliance declaration is given before the builder’s nominated dates (cl 21).

5. Construction phase

   • Give the principal designer 14 days’ notice of intended commencement and of intended building compliance declaration.
   • If a variation occurs that is not a new building element or performance solution, prepare a variation statement (cl 27) and give the original designer access (cl 28).
   • For ground anchors, lodge installation-right documents, destressing and removal plans before work starts (cl 28B) and provide evidence of destressing/removal before occupation certificate or completion (cl 28C–28D).

6. Pre-occupation
   Lodge the building compliance declaration, contractor document, fire-safety certificate and any supplementary details (cl 18). Retain all records for 10 years from completion (cl 84(4)).

7. Ongoing obligations
   Complete CPD each year (Sch 3), retain CPD records for 5 years, notify the Secretary within 7 days of insurance lapse, disciplinary proceedings, or changes in employees/nominees (cl 46). Comply with the code of practice (Sch 4) in all dealings.

Recommended systems

• Maintain a register of all regulated designs, declarations and lodgment receipts.
• Use portal dashboards to track outstanding lodgments.
• Conduct pre-lodgment peer reviews of declarations to ensure all cl 9 matters are addressed.
• For firms, implement a nominee/supervision matrix that maps each project element to an individual whose registration authorises the work.
• Schedule annual insurance adequacy reviews using the cl 77(2) checklist and document the outcome.

Compliance is not a box-ticking exercise at the end of the job; it is a continuous obligation that begins at concept design and continues for a decade after practical completion. Practitioners who treat the planning-portal lodgments as an administrative afterthought are the ones most likely to trigger certifier refusals, disciplinary notices or civil claims for breach of the statutory duty of care.
