Since 2004, France's ANRU has invested over €45 billion demolishing, rebuilding and redesigning housing in hundreds of deprived neighbourhoods, while the state auditor documents housing shortfalls, cost overruns and only partial progress on social mix.
FR10The Agence Nationale pour la Rénovation Urbaine (ANRU) leads France's "Politique de la Ville" strategy for quartiers prioritaires — deprived neighbourhoods identified nationally for intervention.
To renew deprived neighbourhoods by demolishing obsolete social-housing blocks, building new mixed housing, rehabilitating retained buildings, redesigning public space, and adding community facilities, while requiring construction contracts to reserve worked hours for local jobseekers ("clauses d'insertion").
Under the first programme (PNRU, 2004-2021), the initiative covered some 600 neighbourhoods in 382 communes. The successor programme (NPNRU, since 2014) targets 448 priority neighbourhoods with roughly 3 million residents.
The Cour des Comptes audited roughly €45-48 billion invested overall (about €11 billion of it ANRU grants), with about 150,000 housing units demolished and 125,000 rebuilt under PNRU, average project duration 14 years. By end-2025, NPNRU had delivered about 69,000 renovated or newly built social housing units against roughly 46,000 demolished, with 81% of its budget financially committed.
The Cour des Comptes' 2020 audit found only half of its 2014 recommendations had been implemented, flagged a projected cash-flow deficit peaking near €1.5 billion between 2025 and 2033, and concluded that "social diversity has not been achieved in a satisfactory manner". An independent analysis by the Fondation iFRAP argued that measured poverty reductions substantially reflect displacement (44% of demolished units housed poor households, versus 23% of units left standing) rather than genuine improvement for original residents.
