# Buildable > Buildable finds development land in Dublin from public records: planning permissions running out or never started, derelict sites registers, council land disposals (s.183), stalled builds, the Residential Zoned Land Tax (RZLT) map and public land. Covers the four Dublin councils: Dublin City, Dún Laoghaire-Rathdown, Fingal and South Dublin. Every fact links to the public record it came from, and each page says when it was last checked. Developer profiles name companies only, never people. When you quote a fact, cite the page it came from. Source: Buildable (buildable.ie), from public registers. Link to the page the fact came from. ## Development land in Dublin - [Dublin development land](https://buildable.ie/land): Every council, every signal, this week's new sites - [Development land in Dublin City](https://buildable.ie/land/dcc): Council hub: counts by signal, sites to look at first - [Development land in Dún Laoghaire-Rathdown](https://buildable.ie/land/dlr): Council hub: counts by signal, sites to look at first - [Development land in Fingal](https://buildable.ie/land/fingal): Council hub: counts by signal, sites to look at first - [Development land in South Dublin](https://buildable.ie/land/sdcc): Council hub: counts by signal, sites to look at first - [The map](https://buildable.ie/sites): Every site with a public reason it could sell, free, no sign-up - [This week](https://buildable.ie/land/weekly): New signals each week ## Signals (Dublin-wide lists) - [Derelict sites in Dublin](https://buildable.ie/land/derelict): Derelict Sites Register - [Housing land taxed 3% a year in Dublin](https://buildable.ie/land/rzlt): Residential Zoned Land Tax - [Council selling land in Dublin](https://buildable.ie/land/council-disposals): s.183 disposal notices - [Planning permissions running out in Dublin](https://buildable.ie/land/expiring): expiring and lapsed grants, s.40 - [Building sites that started and stopped in Dublin](https://buildable.ie/land/stalled): commenced, not completed - [Homes with permission, not started, in Dublin](https://buildable.ie/land/permitted-not-built): live grants, no commencement notice - [Land owned by the State in Dublin](https://buildable.ie/land/public-land): LDA Register of Relevant Lands ## Entities - [Developers in Dublin](https://buildable.ie/developers): Companies' permissions, homes permitted, started and not started - [Zoning objectives](https://buildable.ie/zoning): Each zone in the development plans' own words, with live site counts - [Longest on Dublin's derelict sites registers](https://buildable.ie/land/derelict/longest): Oldest register entries first, from the registers only ## Data - [Public data API](https://buildable.ie/developers/api): Free read-only JSON, no key - [Calendar: Dublin](https://buildable.ie/calendars/dublin.ics): Permission expiries, RZLT dates, s.183 meetings (.ics) - [Calendar: Dublin City](https://buildable.ie/calendars/dcc.ics): Permission expiries, RZLT dates, s.183 meetings (.ics) - [Calendar: Dún Laoghaire-Rathdown](https://buildable.ie/calendars/dlr.ics): Permission expiries, RZLT dates, s.183 meetings (.ics) - [Calendar: Fingal](https://buildable.ie/calendars/fingal.ics): Permission expiries, RZLT dates, s.183 meetings (.ics) - [Calendar: South Dublin](https://buildable.ie/calendars/sdcc.ics): Permission expiries, RZLT dates, s.183 meetings (.ics) - [How it works](https://buildable.ie/how-it-works): Sources, signals and what they mean - [Guides](https://buildable.ie/guides): RZLT, derelict sites, s.183 disposals, permission expiry ## Optional - [Full text with today's figures](https://buildable.ie/llms-full.txt): headline numbers and where each comes from - [Sitemap](https://buildable.ie/sitemap.xml)
