San Jose, CA Building Permits Guide

By Permit Place  |  Last updated: March 2026

Building permit review in San Jose is among the longest in California, with complex commercial projects routinely taking 40 or more weeks for standard plan review. The city has publicly acknowledged that plan review timeframes are taking longer than usual due to high application volume and limited staff availability. This backlog makes San Jose one of the most challenging permit jurisdictions in the country — and it is why Permit Place created an exclusive Express Plan Check program specifically for San Jose projects. Below is a full breakdown of permit timelines, costs, the application process, the Express Plan Check advantage, and how to navigate the SJPermits portal.

San Jose Express Plan Check – Exclusive to Permit Place

Permit Place has been expediting permits in San Jose since 2003. With over 20 years of direct relationships with the San Jose Building Division, we know the reviewers, the process, and the fastest path to approval. The Express Plan Check program is the result of those relationships — it is not available through any other expediting firm.

What Building Permits Do You Need in San Jose?

San Jose requires permits for most construction activity. The PBCE Building Division issues permits for commercial construction, residential construction, trade work, and specialty projects. The type of permit you need depends on your project scope and whether plan review is required.

Commercial Building Permits

• New commercial construction: Full plan review with the longest timeline. Reviewed by multiple city departments including building, fire, planning/zoning, public works, and environmental. Complex projects face 40+ week standard review
• Tenant improvements and interior buildouts: Plan review for structural, electrical, plumbing, and mechanical changes inside an existing commercial space. Standard review takes 12 to 24 weeks
• Change of use: Required when converting building use (for example, retail to restaurant, office to medical clinic, or warehouse to assembly). May trigger additional fire and planning reviews
• Shell and core: Separate from tenant improvement permits; covers the building envelope and base building systems
• Urban Village projects: San Jose’s Urban Village overlay zones have specific development standards and may require additional planning review and community engagement

Residential Building Permits

• New home construction: Full plan review including structural, mechanical, electrical, plumbing, and Title 24 energy compliance
• Additions and remodels: Required when modifying structure or adding square footage. Kitchen and bathroom remodels involving plumbing or electrical changes require permits
• Accessory Dwelling Units (ADUs): San Jose allows up to 3 ADUs on a single-family lot. Detached ADUs have a 16-foot maximum height and 4-foot rear and side setbacks. No additional parking required within half a mile of public transit
• SB 9 lot splits and duplexes: California SB 9 allows qualifying single-family lots to be split into two lots, with up to 2 units per lot. The two resulting lots must each be at least 40% of the original lot. Owner occupancy required for 3 years. Nearly 60 SB 9 subdivisions have been filed in San Jose as of 2025
• Solar installations: Available as an online over-the-counter permit through SJPermits

What Does Not Require a Permit in San Jose?

Some minor work in San Jose does not require a building permit:

• Painting, papering, tiling, carpeting, and similar cosmetic finish work
• Prefabricated storage sheds under 120 square feet
• Fences up to 3 feet tall in front yards or 7 feet tall in side and rear yards
• Retaining walls under 4 feet in height (measured from bottom of footing to top of wall)
• Replacement of existing equipment in the same location (like-for-like swap)
• Platforms, walks, and driveways not more than 30 inches above grade
• Minor cosmetic repairs that do not affect structural, electrical, plumbing, or mechanical systems

Note: Even exempt work must comply with building codes. If you are unsure whether your project requires a permit, contact PBCE at (408) 535-3555 or [email protected].

Over-the-Counter Permits

San Jose offers online over-the-counter permits for 56 types of simple projects through SJPermits. These include solar panel installations, reroofs, water heater replacements, minor kitchen and bathroom remodels, electrical panel upgrades, HVAC equipment replacements, and other straightforward work. Over-the-counter permits can be issued same-day without a plan review cycle.

Trade Permits

Individual trade permits are typically required for electrical, plumbing, mechanical (HVAC), and fire sprinkler work. These are separate from the building permit and may be pulled by licensed trade contractors. San Jose requires licensed contractors for most trade work.

How the San Jose Permit Review Process Works

Step 1: Determine Your Permit Type

Before applying, determine whether your project qualifies for an over-the-counter permit or requires a full plan review. San Jose’s SJPermits portal includes a project wizard that asks about your project type and scope, then directs you to the correct application path. Over-the-counter permits for simple projects (reroofs, water heaters, solar) can be issued same-day. Projects requiring plan review — including most commercial construction, new residential, and significant remodels — go through the full review cycle.

Step 2: Prepare Your Application

For projects requiring plan review, gather all required documents before submitting. For commercial projects, you will typically need architectural plans, structural engineering calculations, MEP (mechanical, electrical, plumbing) drawings, a site plan, Title 24 energy compliance documentation, and a soils report for new construction. All plans must comply with the 2025 California Building Code (effective January 1, 2026). Projects submitted before December 31, 2025 could use the 2022 codes, but all new submittals now require 2025 code compliance.

Residential projects require construction drawings, a site plan, structural calculations for modifications, and Title 24 energy compliance. ADU projects must include documentation showing compliance with San Jose’s ADU ordinance, including setback dimensions and height calculations.

Step 3: Submit Through SJePlans

Upload your complete construction document set to the SJePlans electronic plan submittal system. SJePlans is the mandatory submission method for all building permit applications requiring plan review. Applications are reviewed for completeness before being assigned to a plan reviewer. Incomplete submissions are returned, adding weeks to your timeline.

For in-person assistance, visit the Permit Center at 200 E. Santa Clara St., Tower 2nd Floor during business hours. Walk-in service is available but hours are limited (see hours above).

Step 4: Plan Review

The city reviews your submitted plans for California Building Code compliance, structural integrity, fire safety, Title 24 energy code, and ADA accessibility. Commercial projects are reviewed by multiple departments concurrently, including building, fire, planning, public works, and environmental services. Standard plan review for complex commercial projects takes 40+ weeks. The city has acknowledged this backlog and recommends adding 2 to 3 weeks to posted timeframes for planning purposes.

San Jose offers an expedited review option for qualifying projects at 1.5x the standard plan review fee. However, even the city’s expedited option does not match the speed of Permit Place’s Express Plan Check program, which delivers comments in 2 to 3 days.

Step 5: Corrections and Resubmittal

If the city issues correction comments, you must revise your plans and resubmit through SJePlans. Each correction cycle can add weeks to months to the total timeline depending on the complexity of corrections and the current backlog. Most commercial projects go through 2 to 4 correction cycles before final approval. Submitting a complete, code-compliant application on the first attempt is critical in San Jose because each correction cycle compounds the already extreme backlog.

Step 6: Permit Issuance and Fees

Once all review departments approve your plans, the building permit is issued and all fees are due. San Jose charges permit issuance fees at $227 per hour (processing and coordination time) and plan review fees at $325 per hour. The city also applies construction tax at $0.28 per $1,000 of project valuation. A 2.4% credit card surcharge applies to card payments. See the full fee breakdown below.

Step 7: Inspections

Schedule inspections through SJPermits.org or by calling (408) 535-3555 as work progresses. San Jose requires inspections at key construction milestones including foundation, framing, electrical rough-in, plumbing rough-in, mechanical rough-in, insulation, drywall (for fire-rated assemblies), and final inspection. The specific inspections required depend on your permit type and project scope. All inspections must pass before a Certificate of Occupancy or final sign-off is issued.

Note: These timelines reflect current review periods as of March 2026. Large or complex projects may take longer. Request a quote from Permit Place for a project-specific estimate, or get an instant due diligence report from PermitNow.io.

San Jose Building Permit Costs

San Jose permit fees are calculated on an hourly basis, with minimums based on project type and scope. The FY 2025-26 fee schedule (effective August 11, 2025) sets plan review fees at $325 per hour (15-minute minimum for over-the-counter, 1-hour minimum for full review intakes) and permit issuance fees at $227 per hour. The city charges whichever is greater: the hourly calculation or the fixed fee for the permit type.

Fee figures sourced from the City of San Jose FY 2025-26 Building Division Fee Schedule. Actual fees depend on project valuation, scope, and plan review hours. Contact the San Jose Building Division or Permit Place for exact costs for your project.

San Jose Permits: Self-Filing vs. Using a Permit Expediter

2025 California Building Code: What Changed for San Jose

Effective January 1, 2026, San Jose adopted the 2025 California Building Code, replacing the 2022 codes that were previously in effect. All new permit applications must comply with the 2025 codes. Key changes affecting San Jose projects include updated energy efficiency requirements under Title 24, revised structural provisions, and new accessibility standards.

Projects that uploaded complete construction documents to SJePlans before midnight on December 31, 2025 were allowed to use the 2022 codes. All projects submitted after that date must meet 2025 code requirements. If you are working with plans designed under the 2022 codes, they will need to be updated before submission.

Permit Place stays current on all California building code changes and can advise on how code updates affect your specific project. Contact us for a code compliance review.

Santa Clara County and San Jose Permit Jurisdiction

San Jose is located in Santa Clara County, which has a population of approximately 1.93 million. If your project is within San Jose city limits, you apply through the City of San Jose PBCE. Projects in unincorporated Santa Clara County outside city limits follow Santa Clara County Department of Planning and Development permitting rules, which have different requirements, fees, and timelines.

Check your project address carefully. San Jose’s city limits include most of the developed urban area, but some properties in the surrounding area fall under county jurisdiction. The SJPermits portal can confirm whether a property address is within city limits.

For Santa Clara County permit information, see our Santa Clara County Building Permits guide.
