The Subdivided Lands Law takes effect at which lot?

The Subdivided Lands Law is designed to regulate the sale of parcels of land that have been divided into smaller lots, primarily to protect consumers from fraudulent practices. This law becomes applicable when a subdivision is created with five or more lots. Therefore, the correct answer indicates that the law takes effect starting with the fifth lot. This threshold ensures that developers must adhere to certain regulations and provide necessary disclosures when marketing these properties, thus offering greater protection to potential buyers in the real estate market.

The other options do not meet the required threshold set by the law, as it specifically begins to apply at the fifth lot, establishing the framework for how subdivisions are handled in California. Understanding this regulatory requirement is essential for anyone involved in real estate transactions in subdivided lands.
