Tips

  • Unlike some jurisdictions, Parker requires a permit for ALL decks regardless of height or size — there is no small-deck exemption threshold published.
  • Retaining/block walls over 48 inches and fences over 6 feet require a permit; shorter structures generally do not, though projects should still be confirmed with staff.
  • Minor residential projects (basement finish, decks, patio covers) can see a much faster 1-5 working day initial review — call ahead to see if your project qualifies for the EZ Permits homeowner track (Wednesdays, 8:30 a.m.-noon, by appointment).
