When a planning commission has adopted a major street plan, no structure shall be erected on any lot within the affected area, nor shall a building permit be issued therefor unless the street giving access to the lot upon which such structure is proposed to be placed has been accepted or opened as or has otherwise received the legal status of a public street prior to that time, or unless such street corresponds with a street shown on the official master plan or with a street on a subdivision plat approved by the planning commission or with a street on a street plat made by and adopted by the commission or with a street accepted by the local legislative body, after submission to the planning commission, by a favorable vote required in La. Rev. Stat. 33:115.

Where a municipality has a planning commission, any structure erected in violation of this Section shall be deemed an unlawful structure, and the municipality may bring suit for a mandatory injunction in any court of competent jurisdiction to compel its removal.  Where a parish has a planning commission, any structure erected in violation of this Section shall be deemed an unlawful structure, and the legislative body can bring an action to remove.
