Tips

  • General repair and small remodel permits are issued over-the-counter at the One Stop office; only new homes, additions over 1,000 sq ft, and 2-story additions require full Plans Examiner review.
  • A single project may require multiple linked permits (e.g., a deck with a ceiling fan and sink needs building, electrical, and plumbing permits).
  • Every permit application and issued permit expires after 180 days without proof of work/progress; one or more 180-day extensions can be granted for a justifiable reason.
