Submit completed permit applications with supporting documents including contractor information, material specifications, and project plans. Commercial projects typically require more detailed documentation.
3. Plan Review
Building officials review submitted plans for code compliance. This may include structural calculations, fire ratings, and material specifications. Review times vary based on project complexity.
4. Permit Issuance
Once approved, pay applicable fees and receive your permit. Keep the permit visible at the job site throughout the project duration.
