- An additional $551 fee will be due to permit an un-permitted system per the Residential Septic Tank Permit Application Requirements.
- A letter from a licensed plumber, detailing the number of individual fixtures and specifying how many toilets are low-flow (1.6 gallons) is required if the health district does not have a fixture count on file, if tenant improvements have been done to the property without health district approval, or if customer wants to reduce fixture unit count on the existing permit for low-flow toilets.

*No portion of the septic system can be under a driveway or any area subject to vehicular traffic or within 10 feet of any tree. Tenant Improvements which impact the septic system will not be approved until all compliance issues are resolved.
**If the property is served by a Community Well, call the Nevada State Division of Water Resources (NSDWR) at (702) 486-2770 to make sure that all fees are current, all paperwork has been filed, and additional plumbing can be approved. Any issues with NSDWR will need to be corrected prior to the health district processing a tenant improvement.
