Move From Digital Plans to a Final Palo Alto Inspection Without Missing the Middle Steps

Palo Alto uses an all-digital permit process. The practical challenge is choosing the right route before uploading: instant permit, building pre-application, Planning Entitlement, Fire permit or Public Works permit.

Use this guide to open the correct portal, prepare the right files, understand City review comments, schedule inspections and prove that the permit is final—not merely approved or issued.

Jurisdiction check

Use the City Portal Only for Property Inside Palo Alto

Use Palo Alto Development Services when

  • The parcel report identifies the property inside the City of Palo Alto.
  • The address appears in the City’s Accela or parcel systems.
  • The work is on a City-regulated residential, commercial or multifamily parcel.
?

Verify before applying when

  • The mailing address says Palo Alto but the parcel may be unincorporated.
  • The property is close to a city boundary or Stanford-area jurisdiction.
  • The City portal cannot locate the address or parcel.
Fast check: Open the Online Parcel Report. Save the APN, zoning district, lot size, flood zone, historic status and known easements before design starts.
Choose the correct route

Instant Permit, Pre-Application or Planning Entitlement?

Instant permit Use only when the exact scope qualifies

Common City routes include qualifying kitchen/bath work, residential reroof, heat pump, certain plumbing work and SolarAPP+ projects.

Accela: Building tab → Create Application

Building pre-application Use for reviewed building permits

New homes, additions, ADUs, structural remodels, tenant improvements and work needing plan review normally begin as a digital pre-application.

Open building-permit instructions

Planning first Check exterior or land-use changes before building

The City directs applicants to Planning for exterior changes, new construction, signs, landscaping, parking changes, subdivisions, use changes and zoning requests.

Apply for a Reviewed Palo Alto Building Permit in Seven Steps

Confirm Planning before finalizing the design

Ask Planning whether the exterior, use, site layout, sign, parking or parcel change requires entitlement.

Do next: Save the Planning file number and conditions of approval for the building upload.

Download the project-specific checklist

Use the City’s forms page—not a general document list—to find the checklist for remodel, kitchen/bath, pool, window, solar, tenant improvement or new construction.

Prepare coordinated PDF files

Make the scope, valuation, plan sheets and forms describe the same project. Use readable PDF bookmarks and clear file names.

Useful names: PA_Address_PLANS.pdf, PA_Address_DOCS.pdf, PA_Address_CALCS.pdf.

Register or sign in to Accela

Open the official portal and use one stable applicant email for all notices and corrections.

Create the pre-application

Choose the Pre-Application tab, select Create Pre-Application, complete the prompts and submit.

Save immediately: The pre-application number, usually formatted like XXAPP-XXXXX.

Upload every required document

Check each file after upload. Missing, mislabeled or unreadable files can prevent completeness intake.

Do not: Upload a partial plan set unless the checklist or coordinator specifically allows it.

Respond to intake and plan-check comments

Use a numbered response letter. State exactly which sheet or document answers each comment.

Start work only when: The permit is formally issued and the official portal shows fees and prerequisites cleared.

Plan review can exceed the inspection-fee component
Planning/zoning plan check
35% of building permit fee for single-family/duplex; 15% for multifamily/commercial
Applies when that review is part of the project
Public Works plan check
35% of building permit fee for single-family/duplex; 15% for multifamily/commercial
Do not include it unless Public Works review applies
Work without permit
2× building permit fee and plan-review fee
Starting early can materially increase cost
Reinspection
Single-family/duplex: $328 primary or $164 secondary inspection type; multifamily/commercial: $164

Component illustration—not a final invoice:

If a qualifying single-family project’s building permit component is $2,457, the listed 125% building plan-check component would be $3,071.25. A 35% Planning review, when applicable, would be $859.95. Other base, Public Works, Fire, impact, utility, school and State fees may still apply.

$2,457 × 1.25 = $3,071.25 · $2,457 × 0.35 = $859.95

Revision

A revision changes a design element in an issued building permit.

  1. Complete the Building Permit Revision Application.
  2. Submit through the same pre-application route as a new permit.
  3. Upload revised plans and an itemized change summary.
  4. Wait for approval before building the changed design.

Deferred submittal

A deferred design element was not included in the issued plan set and is later submitted as a Revision application.

The FY 2026 schedule lists a $694 base fee, with other review charges possible.

Status question
“My record is [number]. Processing Status shows [department/status/date]. What exact document, payment or approval is required for the next step?”
Inspection question
“I need inspection [code/type] for permit [number]. Are all prerequisite inspections complete, and what must be printed and available at the site?”
Expired-permit question
“Permit [number] expired with [remaining inspections]. Should I request an extension or reactivation, and which FY 2026 fee category applies?”

Frequently asked questions

Palo Alto Building Permit and Inspection FAQs

Where do I apply for a Palo Alto building permit?

Use the official Accela Citizen Access portal. Reviewed permits usually begin under the Pre-Application tab. Exact qualifying work may use an instant Building application instead.

Does Palo Alto accept paper building plans?

No. Palo Alto states that building applications and plan review are all digital and paper plan submittals are no longer accepted.

Do exterior changes require Planning approval first?

The City directs applicants to check Planning before a building permit when the project changes the building or site exterior. New construction, signs, landscaping, parking, use, zoning and parcel changes can also require Planning Entitlement.

How do I schedule a Palo Alto building inspection?

Use Accela without login, use the Palo Alto Inspection Request app, or call 650-329-2496 and select option 2. The 101 Final Inspection must be scheduled by phone.

How do I see the latest plan-check status?

Sign in to Accela, open My Records, select the red record number, choose Record Info and Processing Status, then expand the department-review arrow to read the latest marked status, date and comment.

When does a Palo Alto building application or permit expire?

The City says an unissued building application expires 12 months after filing. An issued permit expires 12 months after issuance when no inspections have been completed.

How much does permit reactivation cost?

FY 2026 fees depend on what remains. An expired application is listed at $99 plus applicable plan-check review. Final-only reactivation is $402 or 50% of the original building permit fee, whichever is less. Multiple outstanding inspections can cost 50% of the original building permit fee, subject to City determination.

Can I research Palo Alto permits without an account?

Yes. Permit View provides map-based activity, Accela supports public research, and the Online Parcel Report provides parcel and zoning information. Permit View currently states that it is supported only on desktop devices.

What should be available for inspection?

Keep the printed permit card, a printed large-format approved job set and required installation instructions on site. Make sure the requested stage is complete, visible and safely accessible.

How can I avoid a fraudulent permit invoice?

Do not pay through a separate link in an emailed PDF invoice. Navigate independently to the official Accela Citizen Access portal and verify the fee under the permit record.
