Mount Laurel Doctrines (1975, 1983)
New Jersey's Supreme Court struck down a town's exclusionary zoning, ruling municipalities must provide their 'fair share' of regional affordable housing. The 1983 ruling, Mount Laurel II, gave builders a strong tool to sue towns that resisted.
Dozens of New Jersey towns faced court-ordered affordable housing quotas.
The doctrine remains a landmark precedent for state courts overriding local zoning to address housing shortages.
Like New Jersey's courts, Massachusetts' Chapter 40B uses state power to override local zoning in towns that exclude affordable housing.
