- 1,461 live titles are recorded here, including 257 cross-lease titles (17.6%).

Contextual observations
- Cross-lease titles make up 17.6% of the recorded title mix. That describes the suburb, not any particular home.
- Unit titles account for 7.6% of recorded titles, so title structure can vary within the suburb.
- Public-transport figures describe how recorded titles sit near mapped stops. They do not describe a service from a particular property.
- Coast distance is a suburb-level map measure, not a flood or hazard assessment.
Questions worth investigating
- For any cross-lease property you consider, do the current title, flats plan and lease match what is built today?
- What do the LIM, council property file and a suitable inspection add for the specific address?
No data held for this suburb

The lie of the land in Sumner

Slope is not a measure of ground stability. Sources and limits

24% of Sumner's titles are within 200 m of the sea or harbour edge, 53% within 500 m and 80% within 1 km. The typical title is 440 m away.
Measured in a straight line from the centre of each title's land to the coastline on LINZ's 1:50k topographic map, which follows harbours and estuaries as well as the open coast; lakes and rivers are not included. Distance says nothing about beach access, views or exposure to coastal hazards; council hazard maps and the LIM describe those.

Source: Christchurch City Council, District Plan open data (CC BY 4.0), layers last edited 2026-09-16. Each title is counted once, at the centre of its land, so a title partly inside an area may be counted outside it and the other way round. These are the council's planning maps for the operative District Plan, not assessments of any property: being outside a mapped area does not mean a site is free of that hazard, and being inside one does not describe any particular site. Zone rules set what can be built; check the District Plan, and the LIM for any property.
Room for a small stand-alone unit in Sumner
Since 15 January 2026 a new detached unit of up to 70 m² needs no building consent and, in a residential zone, no resource consent, if (among other conditions) it sits at least 2 m from boundaries and other buildings and the site's building coverage stays at or under 50%. Testing those two dimensional rules against LINZ parcel and building outlines for 1,079 residential sections in Sumner (250–5,000 m²):
| Result of the public-data screen | All residential sections | Cross-lease sections |
|---|---|---|
| No obvious barrier: a 7 × 10 m space fits and coverage would stay at or under 50% | 40% | 20% |
| … of which also in a mapped hazard, qualifying-matter or noise overlay (check needed) | 86% | 82% |
| Space fits but coverage would exceed 50% | 1% | 2% |
| No room for the space | 59% | 78% |
A screen of two measurements, not advice, and never a statement that anything can be built. Building outlines are approximate and leave out decks, sheds, pools and driveways; easements, land covenants, consent notices, pipes, trees, unmapped hazards and district plan rules that still apply are not visible here. On a cross-lease section the other owners' consent and a new flats plan are normally needed as well, and "one unit per site" may mean one for the whole shared section. The council's Project Information Memorandum (PIM) is the authoritative check.
