There are several different processes you can go through to obtain a building permit.
Over the Counter Permits Some permits do not require a plan review and may be issued right over the counter. These permits can be processed in about 20 minutes, only require one or two inspections, and expire after six months.
Over the Counter Plan Review Permits Some permits require plan approval by a building official or inspector which can be done over the counter. These projects must be TRPA QE and require less information than needed for a plan check.
Plan Check Permits Some permits are more complex and require a review of plans, engineering and code requirements. These permits require a plan check process which must be completed prior to issuing a permit. Plan check can take up to 4 to 6 weeks and the process must be completed within 6 months of submission.
