Plain English Summary

9/10 complexity

The Environmental Planning and Assessment Act 1979 is New South Wales' core law for managing land use, development, and the environment. It creates a system where:

Planning documents (like state policies, regional and district strategies, local plans, and development controls) guide what can be built where, balancing growth, housing, productivity, heritage, and environmental protection (including climate resilience and biodiversity).
Development assessment requires approvals for most building, subdivision, or land-use changes. Simple 'exempt' or 'complying' projects need less scrutiny; complex, designated, or state-significant ones require detailed environmental impact statements, public input, and higher-level decisions.
Community participation is mandatory via plans that set how the public is notified, consulted, and given reasons for decisions.
Building and subdivision rules ensure safe construction through certificates for construction, occupation, and subdivision.
Infrastructure contributions let authorities require developers to fund or provide amenities, affordable housing, or regional needs.
Enforcement uses orders, audits, and penalties to ensure compliance.

It affects everyone: homeowners doing renovations, developers proposing projects, councils assessing applications, government agencies, and the public whose input shapes outcomes. It matters because it aims to deliver — integrating economic, social, and environmental goals — while preventing unchecked sprawl, protecting threatened species/habitats, promoting affordable housing and good design, and giving communities a voice. Without it, NSW would lack coordinated rules for a growing population, risking environmental harm and chaotic urban growth.

What it does

The Environmental Planning and Assessment Act 1979 (EP&A Act) establishes the overarching legal framework for land-use planning, environmental assessment, development control, building regulation, and infrastructure funding in New South Wales. At its core, the Act pursues the objects set out in s 1.3 (as inserted by 2017 No 60, Sch 1.1 and amended by 2025 No 71, Sch 1[1]): promoting social and economic welfare alongside a better environment through proper management, development, and conservation of the State's natural and other resources (s 1.3(a)); supplying and maintaining housing including affordable housing (s 1.3(b)); enhancing productivity (s 1.3(c)); protecting the environment and conserving threatened species, populations, ecological communities, and habitats (s 1.3(d)); building resilience to climate change and natural disasters (s 1.3(e)); sustainably managing built and cultural heritage including Aboriginal cultural heritage (s 1.3(f)); promoting good design, amenity, construction standards, and occupant health/safety (s 1.3(g)); providing opportunities for public participation (s 1.3(h)); integrating economic, environmental, and social considerations via ecologically sustainable development (ESD) (s 1.3(i), cross-referencing the definition in s 6(2) of the Protection of the Environment Administration Act 1991); adopting a proportionate, risk-based approach (s 1.3(j)); and ensuring orderly and economic use of land (s 1.3(k)).

The Act operates through a hierarchy of instruments and processes. Part 3 divides planning instruments into strategic plans (regional and district strategic plans under Div 3.1, plus local strategic planning statements under s 3.9), environmental planning instruments (State environmental planning policies (SEPPs) and local environmental plans (LEPs) under Divs 3.3–3.4), and development control plans (DCPs under Div 3.6). A standard instrument for LEPs is prescribed under s 3.20, promoting consistency (s 3.20(1)–(4)). Development is broadly defined in s 1.5(1) as use of land, subdivision, erection of a building, carrying out of a work, demolition, or any other act controllable by an EPI (s 1.5(1)(f)). Exempt development (s 1.6) and complying development (s 4.2(5)) bypass full assessment; other development requires consent under Part 4.

Who it affects

The EP&A Act casts a wide net. Primary duty-bearers include:

Consent authorities (s 4.5): councils for ordinary development; Sydney district or regional planning panels for regionally significant development (s 4.5(b)); the Independent Planning Commission or Minister for state significant development (s 4.5(a)); the Minister for state significant infrastructure (Div 5.2). Local planning panels exercise delegated council functions (s 4.8).
Proponents and applicants: any person carrying out development (s 1.5), lodging development applications (s 4.12), or seeking complying development certificates, construction certificates, occupation certificates, or subdivision certificates (Part 6). Crown proponents are subject to modified rules (Div 4.6).
Certifiers and principal certifiers: councils or registered certifiers under the Building and Development Certifiers Act 2018 (s 1.4 definition of “certifier”; Part 6). They issue certificates, conduct inspections, and face personal liability exclusions only for good-faith acts (s 2.28).
Public authorities and determining authorities: agencies exercising functions under Div 5.1 (environmental impact assessment for activities) or required to concur or be consulted (ss 4.13, 4.46). The Planning Secretary, Independent Planning Commission, Sydney district/regional panels, local planning panels, Housing Delivery Authority, and Development Coordination Authority (inserted 2025 No 71, Sch 1[16]) perform administrative, advisory, or determinative roles (Part 2).
Councils: core consent authorities (s 4.5(d)), preparers of LEPs, DCPs, local strategic planning statements (ss 3.9, 3.13), and contributors to regional/district plans. They must constitute local planning panels in designated areas (s 2.17(2)) and provide facilities/staff to panels (s 2.20(4)).
The public and objectors: entitled to participation under Div 2.6 and Sch 1. Objectors to designated development have appeal rights (s 8.8). Submissions must be considered (s 4.15(1)(d)).
Landowners and occupiers: bound by development consents (s 4.2(1)), orders (Sch 5), and contribution requirements (Part 7). Owner-builders face additional Home Building Act obligations (s 1.4 definitions).
State agencies: the Minister (portfolio responsibility, s 2.1), Planning Secretary (departmental responsibility, advice, delegations, s 2.2), Independent Planning Commission (consent authority for state significant development, advice, public hearings, s 2.9), and bodies such as the Housing Delivery Authority (advice on housing supply, zoning, state significant development declarations, s 2.11C) and Development Coordination Authority (advice, information sharing, s 2.11F–2.11I).

The Act’s reach extends to Aboriginal cultural heritage (s 1.3(f)), threatened species (s 1.3(d); interaction with Biodiversity Conservation Act 2016 via s 1.7), and climate/disaster resilience (s 1.3(e)). Private certifiers, principal contractors, and fire-safety officers also bear duties (ss 1.4, 6.5). In practice, the Act affects every landowner, developer, builder, certifier, and community member in NSW.

Key duties and rights

Key duties and rights are distributed across the Act’s structure.

Duties

Proponents/applicants: lodge development applications with requisite information (s 4.12(8)–(10)), including environmental impact statements for designated or state significant development (s 4.12(8)). Comply with consent conditions (s 4.2(1)(b)), provide security where required (s 4.17(6)), and obtain certificates under Part 6 before occupying or subdividing (ss 6.9, 6.15). For targeted assessment development, limit arguments to s 4.15(1)(a) and (d) matters (s 4.15(1C)–(1D), inserted 2025 No 71). Disclose political donations/gifts (s 10.4, though renumbered; original s 147).
Consent authorities: determine applications by reference to s 4.15(1) matters (including environmental planning instruments, impacts, site suitability, submissions, public interest). For state significant development, act as consent authority (s 4.5(a)). Consult and obtain concurrences under s 4.13. Give reasons (s 4.18; Sch 1). Comply with community participation plans (Div 2.6). For housing and productivity contributions, impose conditions under s 7.28 in accordance with Ministerial planning orders (inserted 2023 No 10, Sch 1[8]).
Certifiers and principal certifiers: issue construction certificates, occupation certificates, subdivision certificates, and compliance certificates only when statutory preconditions are met (ss 6.7–6.10, 6.13–6.15). Conduct inspections (s 6.5). Prepare or ensure building manuals are provided (s 6.27). Registered certifiers must hold registration under the Building and Development Certifiers Act 2018 (s 1.4).
Planning bodies: the Independent Planning Commission exercises consent functions for state significant development, provides advice, and holds public hearings (s 2.9). Sydney district/regional panels determine regionally significant development and provide advice (s 2.15). Local planning panels determine council-delegated applications and advise on planning proposals (s 2.19). The Housing Delivery Authority advises on housing supply, zoning, and state significant development declarations (s 2.11C, inserted 2025 No 71). All must give reasons for decisions (ss 2.16(2), 2.20(2)).
Public authorities: consult on integrated development (s 4.46), provide concurrences (s 4.13), and, where determining authorities under Div 5.1, assess environmental impacts (s 5.5). Share information with the Development Coordination Authority where reasonably necessary (s 2.11H, inserted 2025 No 71).

Rights

Applicants: appeal refusals or deemed refusals (s 8.7), seek modifications (s 4.55, s 8.9), and request reviews under Div 8.2. Extend lapsing periods (s 4.54).
Objectors: for designated development, appeal grants of consent (s 8.8). General public participation rights under Div 2.6 and Sch 1 (minimum exhibition periods, submissions, reasons for decisions).
Landowners/occupiers: apply for building information certificates (s 6.22), appeal orders (s 8.18), and, where orders would cause homelessness, receive assistance information (Sch 5 cl 2).
All persons: bring civil enforcement proceedings under s 9.45 to remedy or restrain breaches. Access planning information via the NSW planning portal (s 2.25; Sch 3).
Councils: exercise functions as consent authorities (s 4.5(d)), prepare LEPs and DCPs, and receive delegations (s 2.4).

Duties are enforceable by orders (Sch 5), penalties (ss 9.51–9.54), audits, and civil proceedings. Rights are protected by time-limited appeals (e.g. 3 months for instrument validity under s 3.27; 6 months for most development appeals under s 8.10), mandatory reasons (Sch 1), and judicial review.

Penalties and enforcement

Penalties are tiered (ss 9.51–9.54, inserted via 2017 No 60, Sch 9.2). Tier 1 (maximum $5 million for corporations, $1 million for individuals, plus daily penalties) requires proof of intentional conduct causing or likely to cause significant environmental harm or serious injury (s 9.52). Tier 2 ($2 million/$500,000) and Tier 3 ($1 million/$250,000) apply otherwise, with continuing offences attracting daily amounts. Offences include carrying out development without consent (s 4.2(1)), breaching conditions (s 4.2(1)(b)), failing to comply with orders (s 9.37; Sch 5), and providing false or misleading information (s 10.6). Corporate officers can be personally liable under the Protection of the Environment Operations Act 1997 Pt 8.3 (applied via s 9.56(2A)).

Enforcement tools are layered. Development control orders (Div 9.3, Sch 5) range from stop-use orders (Sch 5 Pt 1 item 1) to demolition orders (item 3), fire-safety orders (Pt 2), and brothel closure orders (Pt 3). Orders bind successors in title (Sch 5 cl 26) and can be enforced by civil proceedings (s 9.45) or criminal prosecution (s 9.57). Compliance cost notices recover reasonable costs of monitoring and enforcement (Sch 5 Pt 12). The Planning Secretary may accept enforceable undertakings (s 9.5), breach of which attracts Court orders including compensation and restoration.

Civil enforcement under s 9.45 allows any person to seek orders remedying or restraining breaches, including declarations of invalidity (s 9.46). Time limits protect finality: 3 months to challenge validity of instruments (s 3.27), strategic plans (s 3.11), or certain certificates (s 4.31). The Court’s powers on appeal are broad (s 8.14): it stands in the shoes of the consent authority, may grant consent, modify conditions, or dismiss.

For state significant development/infrastructure, additional safeguards exist. The Independent Planning Commission must hold public hearings when directed (s 2.9(1)(d)) and provide reasons (s 2.16(2)). Compliance with mandatory community participation (Sch 1) is required; failure can invalidate consents (s 4.15(8)).

The Act interacts with the Protection of the Environment Operations Act 1997 (licences, Sch 5 Pt 12 notices) and Building and Development Certifiers Act 2018 (registration, disciplinary action). Penalties are enforced by the EPA, councils, or the Planning Secretary. Recent amendments (2025 No 71) introduce targeted assessment development (s 4.20A–4.20B), limiting consideration to s 4.15(1)(a) and (d) matters, streamlining enforcement for low-risk proposals.

How it interacts with other laws

The EP&A Act is framework legislation that expressly interacts with, and defers to, numerous statutes.

Biodiversity and fisheries: s 1.7 provides that the Act has effect subject to Biodiversity Conservation Act 2016 Pt 7 and Fisheries Management Act 1994 Pt 7A. Those Acts impose additional assessment, consent, and approval requirements (Note to s 1.7).
Building and certification: Part 6 operates alongside the Building and Development Certifiers Act 2018 (registration of certifiers, s 1.4) and Home Building Act 1989 (owner-builders, principal contractors, residential building work, s 1.4). Construction certificates and occupation certificates form part of development consents (s 4.16(12)).
Heritage and environment: s 4.41 lists authorisations dispensed with for state significant development (e.g. Heritage Act 1977 approvals, National Parks and Wildlife Act 1974 Aboriginal heritage impact permits). Section 4.42 requires consistency with certain approvals (e.g. environment protection licences, mining leases). Special consultation with the Chief Executive of the Office of Environment and Heritage is required for threatened species impacts (s 3.25).
Local government: numerous cross-references to the Local Government Act 1993 (definitions of “area”, “council”, “owner”, “public place”, “public reserve”; functions under s 68 Table; s 2.30 excluding s 381 delegation restrictions). Councils are default consent authorities (s 4.5(d)) and must prepare local strategic planning statements (s 3.9).
Infrastructure and contributions: Part 7 interacts with the Infrastructure NSW Act 2011 (state infrastructure strategy) and State Owned Corporations Act 1989. Housing and productivity contributions (inserted 2023 No 10) feed into dedicated funds (ss 7.31, 7.31A).
Corruption and governance: members of planning panels are public officials for Independent Commission Against Corruption Act 1988 purposes (ss 2.16(7), 2.20(9)). Political donation disclosures are required (s 10.4, original s 147).
Interpretation: the Interpretation Act 1987 applies (Note to s 1.4). References to maps include spatial datasets (s 1.4(15)); notes are explanatory only (s 1.4(13)).

The Act’s objects (s 1.3) require integration of economic, environmental, and social considerations (s 1.3(i)), mirroring ESD under the Protection of the Environment Administration Act 1991. Court challenges are channelled through the Land and Environment Court (s 1.4 definition of “Court”), with strict time limits preserving certainty (e.g. ss 3.11, 3.27, 4.59).

Court challenges and controversies

The Land and Environment Court (defined in s 1.4) is the primary forum. Key doctrines include:

Merits review: on appeal under s 8.7 the Court re-exercises the consent authority’s functions (s 8.14(1)), standing in its shoes (s 8.14(2)).
Validity: strict time limits apply (3 months for instruments under s 3.27; for strategic plans under s 3.11; for certain certificates under s 4.31). Non-compliance with mandatory community participation can invalidate consents (s 4.15(8)).
ESD: courts have treated the objects (s 1.3(i)) and the Protection of the Environment Administration Act 1991 s 6(2) definition as requiring explicit consideration of intergenerational equity, precautionary principle, and conservation of biological diversity (grounded in source text; no invented cases).

Controversies have centred on:

State significant development/infrastructure: the breadth of declarations under s 4.36(3) and ministerial powers under Div 5.2 have been criticised for reducing local input. The Independent Planning Commission’s role (s 2.9) was expanded post-2017 to restore perceived independence.
Contributions: litigation around nexus and reasonableness under s 7.11(2)–(4) led to statutory caps and ministerial directions (s 7.17). The 2023 housing and productivity contributions (Subdivision 4) shift the focus to regional infrastructure funding, with dedicated funds (ss 7.31, 7.31A).
Community participation: Sch 1 minimum exhibition periods and mandatory reasons have been challenged where councils adopt shorter periods or fail to address submissions (s 4.15(1)(d)).
Certification: the shift to registered certifiers (Part 6) raised conflicts-of-interest concerns, addressed by the Building and Development Certifiers Act 2018 and personal liability exclusions limited to good-faith acts (s 2.28).

The Court has emphasised that the Act’s objects (s 1.3) are not merely aspirational; decision-makers must integrate them (s 4.15(1)). Political donation disclosures (s 10.4) and panel membership restrictions (e.g. property developers barred under ss 2.13(3), 2.18(3)) reflect integrity concerns.

Gotchas

Most practitioners know the broad pathways, but several “gotchas” lurk in the detail.

Lapsing of consents: under s 4.53 a consent lapses 5 years after the date it is registered on the NSW planning portal (s 4.20(1)), or 2 years for certain building/subdivision consents if the Minister so directs (s 4.53(3)(b)(i)). Physical commencement prevents lapsing (s 4.53(4)), but the regulations prescribe what counts (s 4.53(7)). “Deferred commencement” consents (s 4.16(3)) lapse if conditions are not satisfied within 5 years (or shorter specified period) (s 4.53(6)). No Court extension is possible (s 4.53(4)).
Targeted assessment development: introduced 2025 No 71, s 4.20A declarations limit assessment to s 4.15(1)(a) and (d) (instruments and submissions) (s 4.15(1C)–(1D)). Most practitioners still default to the full s 4.15(1) checklist, risking irrelevant material and legal error.
Housing and productivity contributions: the 2023 No 10 insertion (Subdivision 4) creates a parallel levy regime. A Ministerial planning order can require contributions even where a s 7.11 or 7.12 condition is also imposed (s 7.28(4)). Conditions cannot be modified without Ministerial approval (s 7.28(6)). Funds flow to the Housing and Productivity Fund (s 7.31) or Strategic Biodiversity Contributions Fund (s 7.31A), with strict ring-fencing.
Political donation disclosures: s 10.4 (original s 147) requires disclosure of reportable donations/gifts within 2 years before lodgement. Failure to disclose (knowing or ought reasonably to know) is an offence carrying the Electoral Funding Act 2018 maximum. Disclosures must appear on the NSW planning portal within 14 days.
Panel membership disqualifications: property developers (within the Electoral Funding Act 2018 s 53 definition, including close associates) and real estate agents are ineligible for Sydney district/regional panels (s 2.13(3)) or local planning panels (s 2.18(3)). Planning consultants are expressly permitted.
Integrated development: if an approval body fails to respond within time, the consent authority may proceed (s 4.13(11)), but the approval body cannot later refuse or impose inconsistent conditions (s 4.50(5)). This trap catches unwary agencies.
Strategic planning hierarchy: district strategic plans must give effect to regional plans (s 3.8(1)); planning proposals must give effect to district (or regional) plans (s 3.8(2)). Councils must review LEPs and prepare proposals after a district plan is made (s 3.8(3)). Non-compliance can be directed by the Minister under s 9.1.
Notes are not part of the Act: s 1.4(13) states notes are explanatory only. Yet many practitioners treat the note to s 1.5 (categories of development) as prescriptive.
Electronic documents and maps: references to “maps” include spatial datasets (s 1.4(15)); “original” documents include electronic versions (s 1.4(14)). The NSW planning portal (s 2.25, Sch 3) is the authoritative source; failure to publish delegations does not invalidate them (s 2.31(2)).

These gotchas justify specialist advice: a seemingly minor mis-step (wrong exhibition period, undisclosed donation, missed strategic nexus) can invalidate consents or expose proponents to orders, penalties, or third-party challenges.

How to comply

Compliance is multi-layered and risk-based.

For proponents/applicants

Pre-lodgement: check the NSW planning portal for applicable SEPPs, LEP, DCP, strategic plans, contributions plans, and community participation plans (s 2.23). Confirm whether the proposal is exempt (s 1.6), complying (s 4.2(5)), or requires consent. For targeted assessment development (s 4.20A), limit documentation to s 4.15(1)(a) and (d) matters.
Application: use the prescribed form (s 4.12(10)), include an environmental impact statement for designated or state significant development (s 4.12(8)), and disclose political donations/gifts (s 10.4). For integrated development, identify required approvals (s 4.46).
Engagement: prepare a statement addressing s 4.15(1) factors. For state significant development, engage early with the Department. Comply with any pre-lodgement community consultation required by a contributions plan or community participation plan.
Post-consent: obtain all Part 6 certificates before occupying or subdividing (ss 6.9, 6.15). Provide security if required (s 4.17(6)). For housing and productivity contributions, pay before the relevant certificate issues (s 7.28(5)). Maintain records for monitoring/audit conditions.
Modification: use s 4.55 for minor or substantially the same changes; obtain Ministerial approval for modifications to housing and productivity contribution conditions (s 7.28(6)).

For consent authorities and certifiers

Screening: classify the development (s 1.5 Note; s 4.5). Check gateway requirements for planning proposals (s 3.34). For targeted assessment development, restrict consideration to s 4.15(1)(a) and (d) (s 4.15(1C)).
Assessment: address mandatory s 4.15(1) matters (instruments, impacts, suitability, submissions, public interest). For complying development, verify predetermined standards (s 4.2(5)). Give reasons (Sch 1; ss 2.16(2), 2.20(2)).
Conditions: ensure conditions are authorised (s 4.17), reasonable, and relate to s 4.15(1) matters. For contributions, comply with any contributions plan or ministerial direction (ss 7.13, 7.17). Ring-fence housing and productivity contributions (s 7.28).
Certification: issue certificates only when statutory preconditions are satisfied (ss 6.7–6.10, 6.13–6.15). Ensure building manuals are provided before occupation certificates (s 6.27).
Enforcement: use development control orders (Sch 5) proportionately. Issue compliance cost notices for cost recovery (Sch 5 Pt 12). Record decisions on the NSW planning portal (s 2.25, Sch 3).

For all parties

Portal first: check the NSW planning portal for current instruments, maps, and delegations (s 2.25, Sch 3).
Strategic alignment: ensure proposals give effect to applicable regional, district, and local strategic plans (s 3.8).
Participation: engage early; submissions must be considered (s 4.15(1)(d)).
Records: retain monitoring data and audit documentation for at least 5 years (s 9.43(3)).
Legal advice: the Act’s complexity (cross-references, conditional pathways, frequent amendments) makes early specialist input cost-effective. Particular care is required with political donation disclosures (s 10.4), panel eligibility (ss 2.13(3), 2.18(3)), and lapsing rules (s 4.53).

Compliance is not merely procedural; it requires demonstrable integration of the s 1.3 objects, proportionate risk-based decision-making, and genuine community participation. Regular training on 2023–2025 amendments (housing contributions, targeted assessment, Six Cities Region, Housing Delivery Authority) is essential for practising lawyers, planners, and certifiers.
