If interested in installing a simple gray water system for your residence, please read the plumbing code and use the application to apply for permits to install your gray water system. A plumbing permit will be required. Once the application is filed out, interested applicants may submit via the Oakland Online Permit Portal.

This application and permit is intended only for simple systems, such as clothes washer diversion into a gray water system. More complex gray water systems and those proposing storage must submit engineered plans for review and approval as part of their plumbing application.
