Sunnyvale permit work starts with e-OneStop or the Permit Center
Sunnyvale's Permit Center connects online permit accounts, building permit submittals, OTC plan-check appointments, in-person kiosks, and larger project requirements.
Sunnyvale permit questions usually start with e-OneStop or the Permit Center. The right path depends on whether you are opening an online account, submitting plans, booking an over-the-counter review, or asking for counter help.
The Permit Center page explains in-person services and kiosks for account help. For over-the-counter building permit plan-check appointments, it asks applicants to create an online account, generate a new building permit with the project description, submit plans, and then email appointment details such as the permit number, project type, square footage, address, and contacts.
That order helps because Sunnyvale has small home projects, commercial tenant work, tech-campus work, and larger projects that may need extra forms. A counter visit is smoother when the online record already exists.
Before you start, write a one-sentence project description and gather the address, plans, project type, square footage if known, owner or contractor contact, and any prior permit number.
