Port Macquarie-Hastings Council
What a house block can carry in Port Macquarie-Hastings Council's area — the dual-occupancy minimums, the granny-flat rule and the C4 controls, read from the Port Macquarie-Hastings Local Environmental Plan 2011 on legislation.nsw.gov.au, and whether the state Low and Mid-Rise rules reach here.
Dual occupancy (two homes on one lot)
Port Macquarie-Hastings LEP sets no minimum lot size or frontage for a dual occupancy — attached pairs only in R2, judged on Council's DCP; the Lot Size Map governs any split into two titles; outside the state Low and Mid-Rise area.
Secondary dwelling (granny flat)
Port Macquarie-Hastings LEP cl 5.4(9) — the greater of 60 m² or 33% of the house’s total floor area, parking excluded. Under the state Housing SEPP a granny flat of up to 60 m² can also go through the ten-day complying-development route on a lot of 450 m² or more, with a 12 m frontage, where the land is not flood, bushfire or heritage constrained.
C4 Environmental Living
In the C4 Environmental Living zone: a house is permitted; an attached dual occupancy is permitted; no secondary dwelling; no semi-detached pairs. The state Low and Mid-Rise rules do not apply in C4.
Low and Mid-Rise
Outside the Six Cities region. The state Low and Mid-Rise rules do not apply in Port Macquarie-Hastings Council's area — the Port Macquarie-Hastings Local Environmental Plan 2011 and Council's DCP alone govern what a lot can carry. The state granny-flat and Pattern Book routes still apply where the land is not flood, bushfire or heritage constrained.
Constraints that change the answer
Bushfire-prone land (RFS map), flood-control lots, heritage items and conservation areas, and landslip risk all take a lot out of the fast-track routes and into a full DA. Easements, covenants and sewer mains are not on the public maps — a title search and a Sydney Water or council water check are always needed.
Approval routes
- Complying development (CDC) — a private certifier issues it in days where the design meets every state standard; no neighbour notification.
- Pattern Book — the NSW pre-approved designs, ten-day approval, subject to survey (slope) and the site tests.
- Development application (DA) — lodged with Port Macquarie-Hastings Council through the NSW Planning Portal; weeks to months, neighbours notified, merit assessment against the LEP and DCP.
