Build a Complete Napa Permit Package Before You Arrive at the Counter
The City of Napa does not currently accept new building-permit applications through an online submittal portal. eTRAKiT is useful for permit research and inspection scheduling, but it is not the place to upload a new building application.
This guide shows which projects may qualify for over-the-counter or Express Review, what to place in the paper plan set, how to answer plan-check corrections, when outside-agency approvals are required and how to reach a true Building Final.

Understand What Is Paid at Submittal and at Approval
If the city calculates the building permit fee at $6,000, the published 33% plan-review portion would be $1,980 at plan-check submittal. The remaining $4,020 would be due when the permit is approved, before issuance. Outside-agency charges may be additional.
$6,000 × 0.33 = $1,980 plan review · $6,000 − $1,980 = $4,020 balance

Complete the Waste Reduction and Recycling Plan Before Permit Issuance
Covered projects
Projects expected to exceed $100,000 in value or 5,000 square feet must meet the city’s covered-project recycling requirements.
The city identifies a minimum overall salvage or recycling rate of 50% for covered construction and demolition debris.
What to do
- Submit the WRRP before permit issuance.
- Identify intended facilities and material streams.
- Save weight tickets and receipts.
- Submit final compliance documentation.
Napa ADUs Need a Building Permit and a Separate Sewer Permit
Pre-reviewed plans
Napa accepts pre-reviewed ADU plans as part of an application, but every project still receives full site-specific code and department review.
Sewer requirement
The city’s ADU process states that every ADU needs a Napa Sanitation sewer permit before the building permit can be issued.
Review timeline
The published ADU guide identifies an initial 21-business-day review and 14-business-day resubmittal review.
Bring the Solar Package the Counter Expects
Residential solar and battery
The city currently lists residential solar and battery systems for over-the-counter walk-in service Monday through Thursday, 8:30 a.m.–3:30 p.m.
- One application per project
- Two full residential plan sets
- Equipment cut sheets
- Signed homeowner contract
- Active City of Napa business license
Commercial solar
Commercial solar is submitted during the same listed weekday period and requires three full plan sets.
- Title page and site plan
- Structural calculations
- Single-line electrical diagram
- Attachment details
- Footing details for ground-mounted systems
Verify the Contractor Before the Permit Is Issued
Check licensing and insurance
- Verify the California contractor license.
- Confirm the license classification fits the work.
- Check workers’ compensation status.
- Confirm the City of Napa business license.
Control payment risk
- Get multiple bids and references.
- Use a detailed written contract.
- Keep payments aligned with completed work.
- Do not make final payment before the permit is finaled.
Find the Permit, Inspection History and Final Status
Search by permit number first
This normally provides the cleanest record match.
Try the base property address
Remove apartment or suite formatting when a detailed address produces no result.
Check all connected records
A project can have separate building, electrical, plumbing, mechanical, Fire, Planning and Public Works records.
Read the inspection history
Issued or approved does not mean completed. Look for the required final inspection and agency approvals.
Submit a public-record request when needed
Use the City public-record portal when a specific record cannot be found through the online search.
