A final determination of the commission recognizing a claim of vested rights shall constitute acknowledgment that the development does not require a coastal development permit under Public Resources Code, Section 30600 or 30601 provided that no substantial change may be made in the development except in accordance with the permit requirements of the California Coastal Act of 1976. If the approvals upon which the acknowledgment is based lapse either by their own terms or pursuant to any provision of law, the acknowledgment made under this subchapter shall no longer be in effect and the development shall become subject to the permit requirements of the California Coastal Act of 1976.
