# §570.501. General.

- (a) The procedures in 570.502 apply to alterations acquired directly from a lessor by modification or supplemental lease agreement. This is allowed if the following conditions are met:
  - (1) **The alterations fall within the scope of the lease.** Consider whether the work can be regarded fairly and reasonably as part of the original lease requirement.
  - (2) **The lessor is willing to perform the proposed alterations at a fair and reasonable price.**
  - (3) **It is in the Government's interest to acquire the alterations from the lessor.**
- (b) If proposed alterations are outside the scope of the existing lease, decide whether to acquire the alterations through either:
  - (1) A supplemental lease agreement, as justified and approved under 570.502-1.
  - (2) **Government performance or a separate contract.** The lease must first provide the Government the right to perform alterations to the leased space.
