Restrictions on the construction of Build To Rent apartment blocks are being proposed as part of Dublin City Council's new development plan.

Members of the public are being invited to give their views on the draft plan, which aims to accommodate 40,000 new housing units up to 2028.

The new restrictions would limit Build To Rent complexes to areas in the inner city within 500 metres of areas of high employment or major transport interchanges such as train stations.

They would also be allowed in 17 designated Strategic Development Regeneration Zones in areas such as Clongriffin, Ballymun, Finglas, Cherry Orchard and a number of city centre locations.

The developments would have to have at least 100 units in total with at least 40% being built to sell.

The number of one-bed units would be limited to 50% of the total and studios would make up a maximum of 25% of any such scheme.

Lord Mayor Alison Gilliland said there is concern that the over proliferation of Build To Rent developments will not provide high standard, sustainable housing.

"The new approach will help ensure that large scale developments comprise a broader range and mix of apartment typologies with a better standard of amenity, therefore more appropriately addressing the diverse needs of those seeking housing in our city," she said .

Any new housing developments of over 15 units in The Liberties or North Inner City would face higher requirements with at least 15% of units having to be three-bed and the proportion of one-bed limited to 30%.

This is because those areas already have a concentration of smaller units and Build To Rent developments, according to the draft plan.

In general there will be policy to prevent clustering of Build to Rent and student accommodation and a presumption against new co-living developments.

City Planner John O'Hara said: "The new plan has come at a time of unprecedented challenges for the city arising from the impacts of the Covid-19 pandemic, Brexit and climate change."

One developer has predicted that the restrictions on Build To Rent proposed by Dublin city councillors will lead to a massive reduction in new planning applications.

Director of Twinlite development company Rick Larkin said it is not economically viable to build a block of apartments for sale in Dublin at the moment with construction costs of €411,000 per two-bed unit.

He said with construction inflation in Ireland now at around 30%, Build to Rent is becoming uneconomical as well.

"Attacking the rental sector will not help the viability of build for sale, all it will do is reduce the supply of rental properties," he said.

Mr Larkin added that the draft development plan does not include a single measure to make build for sale more viable.
