SB 172 Louisiana Senate · 2026 Regular Session

PLANNING/ZONING: Provides relative to planning commissions. (8/1/26)

This bill sets a 60-day deadline for planning commissions to approve or disapprove land subdivision maps (plats), with written reasons for rejections. It requires public hearings for most submissions, including newspaper notices and certified mail, but allows commissions to waive hearings for small subdivisions (5 or fewer lots, no new streets) in large municipalities (over 150,000 population). Approved plats automatically become part of the local official land-use plan, though approval doesn’t mean public acceptance of streets or open spaces shown. The bill directly affects local governments, planning commissions, and developers seeking subdivision approvals in Louisiana.
