How prices are measured on this page
Typical price is the median: half the sales were above it and half below. Average price is the mean, which a few very high or very low sales can pull up or down. They are two measures of the same sales, so they are expected to differ.

| 2020 from Jun | 186 | €600,000 | €737,353 |

Transport, broadband and zoning
Public transport stops inside the Blackrock boundary, ComReg's fixed broadband coverage for its Small Areas, and how the current development plan zones the land.
- Rail and DART
- Blackrock, Booterstown, Seapoint
- Stop density
- 107 stops across 7.58 km², about 14 per km². Bus stops are counted per pole, so a road served in both directions counts twice.
Broadband figures are ComReg's averages across the 110 Small Areas that make up Blackrock: 97% of premises passed by a gigabit network and 68% connected. They describe the area, never one address.
Land use. 72% of the zoned land is residential under the current development plan, 2022 to 2028, 627 hectares in all.

|---|---|---|---|
| R2 | Existing residential | 451.5 | 72% |
