Application Process

1. Confirm whether the work needs a permit and whether outside agency approvals are required. Dublin states most construction, repair, electrical, plumbing, and mechanical work needs a permit.
2. Create a CSS account and start the permit application online. Dublin's CSS page includes account-creation and application guides.
3. Upload the application and required digital submittals. The municipal code requires an application form, property location, applicant contact information, signature, work description, proposed use/occupancy, valuation, and other information reasonably required by the Building Official. Plans are submitted digitally unless the Building Official authorizes paper.
4. Upload plans, specifications, and supporting reports if required. Depending on scope, Dublin may require engineering calculations, soil/geologic reports, load and utility demand calculations, and a special inspection program.
5. Pay the permit fees through CSS. For some over-the-counter permits, Dublin says fees may also be paid at the building counter, but issuance still occurs through CSS.
6. Respond to plan check comments if the project is not eligible for instant or over-the-counter issuance.
7. Once approved and issued, print the permit record, approved documents, and inspection record card, keep them on site, and schedule inspections through CSS.
8. Obtain final approval before occupying or using the work.
9. Processing time estimate if available: Dublin states plan-review permits typically take about 2 to 3 weeks (10 to 15 business days). For over-the-counter residential permits, Dublin says status notification is typically sent within 3 business days, and certain instant permits are issued once submitted and paid.

General Requirements

Dublin Municipal Code 7.28.300 requires a permit before installing, erecting, constructing, enlarging, adding to, altering, repairing, moving, removing, demolishing, converting, occupying, equipping, or improving a building, structure, facility, or electrical/plumbing/mechanical installation, except listed exemptions. The City also says permits are required for most construction and repair work.

Required Documents

• Permit application; project address/legal description; applicant name/address/phone; applicant signature or authorized agent; work description; proposed use/occupancy; valuation; flood-hazard nonconversion agreement if applicable; digital plans/specifications unless paper is authorized; and, when required, engineering calculations, stress diagrams, soil/geologic reports, electrical load calculations, gas/water demand calculations, and a special inspection/testing program.

Permit validity

Issued permits with valuation under $1,000,000 expire 1 year from issuance; permits over $1,000,000 expire 2 years from issuance. Permit applications expire 6 months after plans/specifications have been checked. Permit extensions may be granted in writing for up to 180 days each; application extensions may be granted in writing for up to 90 days each if requested before expiration and justified.

Building code

Dublin states it is currently using the 2025 California Building, Residential, Electrical, Mechanical, Plumbing, Energy, Fire, Existing Building, Green Building Standards, Wildland-Urban Interface, Swimming Pool and Spa, Building Maintenance, Floodplain Management, and Building Administration codes, with Dublin Municipal Code amendments.

Owner-builder

Dublin requires the property owner to sign and return the Owner-Builder Acknowledgment before permit issuance. The form warns that owner-builders assume legal and financial responsibility, may become employers if unlicensed labor is used on jobs of $500 or more, and cannot build single-family homes for sale unless the statutory licensed-contractor conditions are met.

Contractor requirements

Dublin's owner-builder form states contractors must be licensed and bonded in California and must list license numbers on permits and contracts. Dublin's over-the-counter permit handout also says the contractor's City of Dublin business license must be current.

Fees

Minimum permit fee

$51.00 effective 7/1/2025 for valuation from $0 to $500 under the Building and Safety valuation table

Plan check fee

Dublin's public schedule does not separately break out a standard initial building plan-check fee on the main valuation table. It does list "Additional plan checking, alternate means and methods applications, or plan revisions" as Time and Materials, and an expediting fee of 150% of plan check fees when approved by the Building Official.

Permit fee formula

Mixed. Standard building permits use a valuation-based fee table. Many common residential scopes use flat fees. Additional time-and-materials charges apply for certain special services and plan revisions.

Reinspection fee

Reinspection fee is $241.00 each effective 7/1/2025. The municipal code requires a reinspection fee if more than one reinspection is needed for corrections, if work is not ready when called, or if approved plans/specifications are not on site. After-hours service is $340.00 per hour with a 4-hour minimum if requested outside regular working hours/business days.

Payment note

Dublin says fees can be paid through CSS, and some over-the-counter permit fees may also be paid at the building counter. The master fee schedule also lists a 2% technology surcharge on permit cost and a 3% credit card transaction fee where applicable. For T&M applications, additional deposits may be collected and remaining funds are refunded after completion.

Fees change. Verify current amounts at the official fee schedule.
