Community Participation Plan (CPP, NSW)

Every NSW council's CPP under EP&A Act Schedule 1 sets notification, exhibition periods (14-28 days), site signs, and ads for each development class.

A Community Participation Plan (CPP) is the mandatory document every NSW council must publish under the Environmental Planning and Assessment Act 1979 (NSW) Schedule 1 Part 2, setting out who gets notified for each class of development application, the minimum exhibition period (14 days minimum, often 21 or 28 in larger councils), and whether site signs and newspaper advertising are required. The CPP is layered on top of the EP&A Regulation 2021 minimums; councils can require more public engagement than the regulation sets, but cannot require less. The CPP is the single document a builder reads before lodging a DA to know how the notification will run and how long the timeline will stretch. Verified per EP&A Act 1979 Sch 1 Pt 2 (2026-05-23).

Why every council has its own CPP:

The NSW planning system delegates community participation design to each council so that local conditions (precinct density, historical objection patterns, neighbourhood complexity) can be reflected in the notification rules. A semi-rural shire and a metropolitan inner-city council have very different community-participation needs; the CPP framework lets each council tailor the rules within state-set minimums.

What’s in a CPP:

SectionContent
Plan policy and objectivesThe council’s community-engagement principles
Notification matrixFor each class of development (DA, modification, complying, planning proposal): who gets notified, how, and for how long
Exhibition periodsMinimum days for online posting and physical notification
Site sign requirementsWhere required, what size, what content, how long displayed
Newspaper notificationWhere required (often only for state-significant or larger development)
Mailed letter requirementsWho gets the mailed letter (adjoining + adjacent owners, often within a defined radius)
Submissions handlingHow submissions are recorded, considered, and responded to
Stakeholder engagementPre-DA stakeholder meetings, late-stage notification, IHAP/RPP referrals

Typical CPP notification matrix (example from a metropolitan council):

Development classOnlineLetterSite signNewspaper
Standard residential DA14 daysAdjoining + adjacent (within 50 m)YesNo
Major residential DA (multi-unit, mid-rise)21 daysAdjoining + adjacent (within 100 m)YesNo
Heritage item DA21 daysAdjoining + adjacent + heritage stakeholdersYesSometimes
State-significant DA28 daysAll adjoining + community + state agenciesYesYes
Section 4.55 modification14 daysAdjoining onlyNoNo
Designated development30 daysExtended adjoining + stateYesYes

(Actual periods vary by council; example only.)

Minimums under EP&A Regulation 2021:

The state floor (which councils may exceed):

ElementMinimum
Local development DA14 days online + letter to adjoining
Designated development30 days
State-significant development28 days
Public-priority infrastructure30 days

A CPP that sets shorter than these minimums is invalid and the council must default to the regulation periods.

How to find a council’s CPP:

  1. Council website → planning department → community participation plan (or “DA process” page).
  2. Or NSW Planning Portal → council page → CPP link.
  3. Common file name: “Community Participation Plan 2025” (updated as council reviews them, typically every 3-5 years).

Why builders should read the CPP early:

ReasonImpact on the project
Exhibition period14 vs 28 days changes the DA timeline by 2 weeks
Notification radiusWider radius means more potential objectors; consult pre-lodgement
Site sign requirementBuilder typically arranges; cost $200-$500
Newspaper notificationWhere required, $500-$1,500 advertising cost added
Special-class notificationsHeritage, environmental, infrastructure may trigger additional consultations

Common defects:

  • Builder assumes “14 days” without reading the CPP: council actually requires 21; DA timeline understated.
  • Adjoining-only notification assumed when 50 m radius required: missed notification → council requires re-notification → 2-4 week delay.
  • Site sign not posted within the required window: re-notification required.
  • Newspaper ad missed when required: re-notification; if particularly delayed, fresh DA lodgement may be required.

Cross-state equivalents:

Builder takeaway:

  • Download the council’s CPP at the start of the DA preparation. Read the notification matrix for your development class.
  • Calendar the exhibition period into the project program. 14 days vs 28 days vs 30 days adds 2-4 weeks of waiting per DA.
  • Arrange site sign printing and posting in the first week of lodgement.
  • Pre-DA stakeholder consultation (where the CPP requires) reduces formal objections later.
