What Inspectors Look For  |  What You Should Do During an Inspection | Your Statutory Protections

An Inspection Has Three Possible Results


No Violation

  Notice to Comply
A "warning" of a
minor non-compliance
  Notice of Violation (NOV)
Issued at the jobsite, if responsible party is present to sign. Otherwise, will be issued via U.S. mail
    Follow-Up Inspection
Within 10 days to determine if non-compliance has been cured
  Inspector assembles a
referral report
If there are no instances of non-compliance, further action is unlikely
An inspection supervisor reviews the referral report and determines its merits
Notice to Comply may be an aggravating factor in the future
If the non-compliance has not been cured, or if other potential violations are found, the inspector may issue a Notice of Violation (see right column) If the referral report warrants action by the County, the supervisor edits the report
and forwards it to Enforcement staff

Mitigating and Aggravating Factors

III. Notice of Violation

Enforcement staff:

  • applies the County's penalty policy,

  • calculates the fine, and

  • issues an Order of Abatement.

The contractor hires an attorney (Why?)

  • The contractor may settle the violation by signing the Order and paying the fine.

  • The contractor may request a hearing to challenge the Order of Abatement.

  • If the hearing officer upholds the Order of Abatement, the contractor may appeal to Superior Court.

  • The contractor may also request a settlement conference, at which the County will be represented by the County Attorney.
