If you feel that an item is not applicable to your project, note “N/A” and discuss the reason with the plan checker.Please indicate the sheet number and detail to the right of each correction, or note the number on the plans where the correction is made. A separate sheet for response may be used. Resubmit marked original, calculations and this correction sheet. Resubmit corrected sets of plans.Meetings between the project applicant/designer and the plan reviewer shall be by appointment only.
This review does not include mechanical, plumbing or electrical work. Separate plans, applications, fees, plan checks, and permits are required for mechanical, plumbing, and electrical work. Call 647-5800 for information.
The applicant shall obtain clearances/approvals for the following, prior to building permit issuance:

- Proof of Worker's Compensation Insurance shall be required at the time of permit issuance.
Compliance with AE zone is not required when floor area calculation shows all 3 areas of addition do not exceed 40% of floor area of existing house.
This project is in a special flood hazard area designated on the flood insurance rate map (FIRM) as zone A or AE. This zone requires that the lowest finish floor elevation (including basement) of the structure shall be at (or above) base flood elevation determined by a hydrology study for the A zone, or at (or above) the base flood elevation specified for the AE zone, on the flood insurance rate map. All elevations must be referenced to the National Geodetic Vertical Datum.
