Can I build a duplex or granny flat in Ryhope?
Most of Ryhope is land this tool does not answer for. 25 of the 25 blocks we checked sit in rural, conservation, industrial or special-purpose zones rather than a residential one, and Block Checker covers residential zones only. The counts below are what it could assess — they are not a finding that nothing can be built. For land like this, a planner reads the LEP for the zone directly.
Ryhope sits in Lake Macquarie City Council's area under Lake Macquarie Local Environmental Plan 2014. We ran 25 real Ryhope addresses through the checker: the typical block is 1,007 m² with 20.1 m of frontage. Most of them are not residential land, so see the note below before reading the counts.

A granny flat
0 of the 25 blocks we checked could take one. Lake Macquarie LEP cl 5.4(9) — the greater of 60 m² or 25% of the house’s total floor area, parking excluded. Separately, the state Housing SEPP allows a granny flat of up to 60 m² 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.
Dual occupancy (duplex) rules in Ryhope
0 of the 25 blocks we checked could carry two or more separate homes today.
Lake Macquarie LEP sets no minimum lot size or frontage for a dual occupancy — R2 permits ‘residential accommodation’ as a group term, so it is judged on Council's DCP; the Lot Size Map governs any split into two titles
Low and Mid-Rise
None of the 25 blocks we checked fell inside the state Low and Mid-Rise area, so in this part of Ryhope the LEP minimums are what count. The boundary is a walking distance from a listed centre, so it can cut through a suburb — the checker reads which side of it your own address sits on.
What else turned up
25 of 25 were on bushfire-prone land. Any of those takes a block out of the fast-track routes and into a full DA, so it changes the answer more than the lot size does.
How we got these numbers
We took 25 real Ryhope street addresses from the NSW geocoder and ran every one through the same engine this site runs for you, reading the planning controls live. Nothing here is modelled or estimated.
It is a sample, not a census. The addresses are a spread across what the geocoder returns, so treat these as "of the 25 blocks we checked" rather than a figure for every block in Ryhope. Your own block is the only one that answers for itself — that is what the box on the right is for.
