Tips

Overall statutory review timeframe for a new single-family or two-family dwelling is 45 working days (10 working days Administrative Completeness Review + 35 working days Substantive Review), per ARS 9-835/9-836 and the City's published timeframes.
Applications and plans must be complete at time of submittal; mid-cycle additions or revisions are treated as a full resubmittal and reset the review timeline (per Arizona SB 1598 compliance policy).
If the project is in a Historic District or Overlay, Heritage Preservation Commission approval or a Cultural Resource Study may be required before submitting the application.
A plan review deposit is required at submittal; if the application is denied for failure to respond within the overall timeframe, re-applying requires paying one-half the original plan review deposit again.
