Depending on things, you might enter a land purchase (or lease) contract that's contingent on issuance of a building permit.

But a seller would probably prefer to sell without contingency, so what terms are available depends on market conditions.

Title insurance for residential real estate may sometimes cover properties that are unbuildable due to unsatisfiable permit requirements.

All told, it's easier as a buyer if you purchase an existing structure that was built under permits and is currently in use under appropriate occupancy permits.
