Permit basics

What the City of Sunnyvale Permit Center Does

The City of Sunnyvale One-Stop Permit Center provides streamlined review for development projects and building plans. Services include Building, Fire, Planning and Public Works Engineering review, making it the main starting point for building and development permits.

For property owners, the practical value is simple: the Permit Center can help you understand what process your project must follow, what documents are needed and whether the project needs plan review. If this is your first Sunnyvale project, the City itself recommends calling the Permit Center to understand your project’s needs before you apply.

Building Safety

Handles building permit and code-related questions for construction, remodeling, alterations and safety compliance.

Planning

Reviews zoning, design, land use, planning applications, ADUs and development standards when applicable.

Fire and Public Works

Fire Protection Engineering and Public Works Engineering may review fire, hazmat, right-of-way or engineering-related work.

⚠️
Before starting work: Do not assume your project is exempt. Sunnyvale’s Permit Center tells first-time applicants to call and confirm the project process, needed documents and plan review requirements before starting.

Avoid mistakes

Why Sunnyvale Building Permits Get Delayed

Most delays happen because the wrong project type is selected, old forms are uploaded, the applicant misses E-OneStop comments, planning review is needed, or inspections are scheduled before the work is ready.

Common delay
What it usually means
How to avoid it
Old portal account issue
Existing customer did not re-register after the 2024 system upgrade.
Re-register using the current email address on file.
Wrong project type
The selected application route does not match the work.
Use Online Services Help and call the Permit Center if unsure.
Missing Building and Fire Permit Application

Confirm all department reviews before assuming a simple building permit.
Inspection not ready
Work was covered, inaccessible or incomplete at inspection time.
