City of Napa Building Department: Permits, Plan Review, Inspections, eTRAKiT and Official Contact
Planning construction in Napa requires careful attention because the city does not use an online portal for permit submittals, but it does use eTRAKiT for online inspection scheduling. A project may need over-the-counter permit processing, express review, full plan review, sanitation review, school district development fees, planning review, fire review, stormwater review, special inspections or final approvals from multiple city and outside agencies.
This guide explains the official City of Napa Building Division process in simple language, so homeowners, contractors, designers, business owners and property buyers can avoid wrong assumptions, missed submittal windows, incomplete plans and inspection delays.

What the City of Napa Building Division Does
The City of Napa Building Division helps property owners, contractors and design professionals with building permits, plan review, permit issuance and inspections for construction work inside the City of Napa.
The city’s building permit process is different from many modern cities because Napa clearly states that it does not have an online portal for permit submittals. This makes it more important to use the correct application, prepare complete plan sets and submit during counter hours.
Permit review options
Napa uses over-the-counter permits, express review and full plan review depending on project complexity.
Plan review
Projects with plans must include enough detail to show location, nature, extent of work and code compliance.
Inspections
After permit issuance, required inspections can be scheduled by automated phone line or eTRAKiT.
City of Napa Permit and Plan Review Options
Napa offers different review paths depending on the project. The city encourages applicants to contact the Building Division before submitting to confirm the correct permit and plan review option.
Review type | City guidance | Practical tip |
|---|---|---|
Over-the-counter permit | Used for projects that do not require plans. Examples include electrical service change-outs, furnace and water heater change-outs and roofing. | Bring a completed application with an accurate work description. |
Express review | Used for minor building projects where plans can be reviewed at the counter in about 10-15 minutes. | Examples include minor residential interior remodels, rooftop PV under 10KW, window/door replacement, seismic upgrades and patio covers. |
Commercial TI limitation | Commercial tenant improvement projects are not eligible for Express Review and must use Rapid or Full review. | Commercial applicants should plan for more review time and more complete submittal documents. |
Full review | Plans are reviewed within 21 business days of submittal. | Use three to six sets of plans and additional documentation as required by submittal checklists. |
2025 California Codes | Permits applied for on January 1, 2026 or after must comply with adopted 2025 California Codes. | Make sure your designer, contractor and energy documents use the correct code cycle. |
Work That May Be Exempt From a City of Napa Building Permit
Napa’s permit information page references 2025 California Building Code section 105.2 and lists building work that may be exempt from permits. However, the city also states that all work, including work exempt from permits, must comply with applicable codes and ordinances.
Possible exemption | City-listed condition | Practical warning |
|---|---|---|
Small accessory structures | One-story detached accessory structures used as tool/storage sheds, playhouses and similar uses, with floor area not greater than 120 square feet. | Planning setbacks, zoning and flood/fire rules may still apply. |
Fences | Fences not over 7 feet high. | Height, location, visibility, historic district or planning rules may still matter. |
Retaining walls | Retaining walls not over 4 feet from bottom of footing to top of wall, unless supporting surcharge or impounding certain liquids. | Slope, drainage and surcharge conditions can trigger permit or engineering needs. |
Water tanks | Water tanks supported directly on grade if not greater than 5,000 gallons and height-to-diameter or width ratio is not greater than 2:1. | Fire, zoning, utility or site rules can still apply. |
What to Prepare Before Submitting a Napa Building Permit
Because Napa does not currently offer online permit submittals, your counter package should be organized and complete before you arrive. Missing plan sets or unclear work descriptions can turn a simple visit into a return trip.
Completed application
Use a current city application and write a clear, accurate work description.
Plan sets
Express and full review projects may require multiple plan sets in minimum paper sizes specified by the city.
Submittal checklists
Use the official applications, checklists and forms page before visiting the counter.
Outside agency items
Napa Sanitation District or Napa Valley Unified School District review or fees may apply depending on scope.
Code cycle
Permits applied for on or after January 1, 2026 must comply with adopted 2025 California Codes.
Inspection planning
After issuance, plan inspections at least 24 hours ahead and understand AM/PM windows.
Napa Sanitation District, School Fees and Other Agency Reviews
The Building Division page notes that some projects may trigger outside agency review or fees. This is easy to miss if you only think about the building permit.
Agency or review | Official note | Practical step |
|---|---|---|
Napa Sanitation District | Depending on the scope of work, the project may trigger review from Napa Sanitation District. | Contact NapaSan directly at 707-258-6000 if sewer, fixture, tenant, commercial or occupancy changes may apply. |
Napa Valley Unified School District | Depending on scope, the project may trigger submission of development fees from NVUSD. | Contact NVUSD directly at 707-253-6281 for school fee clarification. |
Fire Hazard Severity Zone maps | Napa references adopted Local Responsibility Area Fire Hazard Severity Zone maps from the State Fire Marshal. | Check fire hazard mapping and fire-related requirements for affected properties. |
Final agency approvals | Napa’s inspection page lists final approvals from fire, sanitation, planning, flood control, public works, health and utilities where applicable. | Do not request final building too early if outside finals remain open. |
How to Schedule City of Napa Building Inspections
Napa building inspections are offered Monday through Friday except city holidays. Inspections must be scheduled at least 24 hours ahead and are offered in AM or PM windows.
Inspection item | Official guidance | Practical tip |
|---|---|---|
Phone scheduling | Call the automated inspection line at 707-257-1063 and select the correct inspection code. | Have your permit number and inspection code ready before calling. |
Online scheduling | Use eTRAKiT online inspection scheduling. | Remember eTRAKiT is for inspection scheduling, not permit submittal. |
Advance notice | Inspections need to be made at least 24 hours prior or planned ahead. | Do not schedule trades tightly before confirming inspection timing. |
Time windows | AM window is 8 AM-12 PM; PM window is 12 PM-4 PM. | Inspectors cannot call when on the way or give a narrower time window. |
Final approvals | All applicable finals must be approved before Building Final. | Check fire, sanitation, planning, public works, stormwater, utility and other finals if listed on your project. |
Common Napa Inspection Types and Final Approvals
Napa publishes many inspection codes. Your specific permit will determine which inspections are required, but the examples below show why checking the inspection list early matters.
Inspection group | Examples | Practical note |
|---|---|---|
Underground | Underground DWV, underground electric, underground gas and underground water. | Call before covering trenches or underground work. |
Foundation | Setbacks, footings/steel, piers and slab reinforcement. | Do not pour concrete before required inspection approval. |
Rough trades | Rough framing, rough electric, rough mechanical, rough plumbing and gas test/release. | Rough work must be visible and ready for inspection. |
Insulation and drywall | Underfloor insulation, wall insulation, ceiling/attic insulation and drywall/sheetrock. | Do not cover walls or ceilings until required rough inspections are complete. |
Pool and spa | Pre-gunite, pre-deck, pre-plaster/pool barrier and underground pool plumbing/electrical. | Pool projects have several timing-sensitive inspections. |
Final approvals | Fire Prevention, Napa Sanitation, Planning Division, Flood Control, Public Works, Napa County Health, stormwater, water utilities and 999 Final Building. | All applicable finals must be approved before Building Final. |
ADUs, EV Chargers, Solar PV, Swimming Pools and Waste Reduction Plans
The Building Division links to special resources for common high-demand projects. Use these official pages early because project-specific rules can change what you need to submit.
Accessory Dwelling Units
ADU projects can involve planning, building, sanitation, school fees and utility considerations.
Electric Vehicle Charging Station
EVCS projects may have specific checklist and permit review requirements.
Solar PV
Rooftop PV under 10KW may qualify for express review, but always check current Napa requirements.
Swimming pools
Pool and spa work has multiple inspection stages and barrier/final approval requirements.
Waste reduction
Some projects may require a Waste Reduction & Recycling Plan or materials diversion steps.
Address changes
New or changed addressing may require separate city processing before records are correct.
City of Napa Permit Fees, Refund Policy and Review Timing
The Building Division links to the city’s Master Fee Schedule and Refund Policy. Fees can depend on project type, valuation, review route, outside agency requirements and revisions.
Master Fee Schedule
Use the official fee schedule before budgeting for permits, plan review and related project costs.
Full review timing
Full plan review is listed as within 21 business days of submittal.
Outside fees
Napa Sanitation District and Napa Valley Unified School District fees or review may apply depending on scope.
Refund policy
Check the city’s refund policy before canceling or changing a submitted permit.
Permit Records, eTRAKiT and Property Due Diligence in Napa
eTRAKiT is mainly highlighted by the city for online inspection scheduling, but property owners and buyers should still keep a complete project file because permit and inspection records can matter during resale, refinance, insurance and future remodels.
Keep permit documents
Save applications, stamped plans, permit card, fee receipts and inspection results.
Check final approvals
Make sure all required agency finals are cleared before relying on the project as complete.
Ask before buying
Ask sellers about open permits, unfinaled work, ADUs, pools, roof work, solar and remodels.
Why City of Napa Building Permits and Inspections Get Delayed
Most delays are preventable. They usually happen because applicants expect online submittal, arrive after the 3:30 PM submittal cutoff, bring incomplete plans, miss outside agency reviews or schedule inspections before work is ready.
Common delay | What it usually means | How to avoid it |
|---|---|---|
Assuming online permit submittal exists | The city states there is no online portal for permit submittals. | Use official counter/application instructions and contact Building Division before submitting. |
Late counter arrival | Last submittal and/or permit issuance is 3:30 PM. | Arrive earlier with complete documents and questions prepared. |
Incomplete work description | Staff cannot determine scope or review route. | Write a clear description and include plan details that show location, nature and extent of work. |
Wrong review path | The project may not qualify for over-the-counter or express review. | Contact the Building Division before submitting, especially for commercial tenant improvements. |
Outside agency review missed | NapaSan, school district, planning, fire, public works or flood/stormwater final may apply. | Ask about outside agency approvals before scheduling construction. |
Inspection not scheduled early enough | Inspections must be requested at least 24 hours ahead. | Use 707-257-1063 or eTRAKiT early and plan around AM/PM windows. |
