The State Subdivision Map Act, current case law, and local ordinances are used to determine parcel legality.

In cases where a parcel was not created legally, the property owner is given the opportunity to apply for a conditional certificate of compliance.

No, a certificate of compliance neither ensures that a parcel is buildable nor does it entitle the property owner to a construction permit or other development permits or approvals.
