Orange County Development Services provides building, grading, plan-review, inspection, zoning, and code-enforcement services for unincorporated areas of Orange County and County-owned projects. It is not the building department for incorporated cities such as Anaheim, Irvine, Santa Ana, or Huntington Beach. The city or town where the parcel is incorporated normally controls its own building permits and zoning; confirm the boundary before using myOCeServices.

Orange County unincorporated building permits and plan review

OC Development Services’ Building and Safety service reviews building and grading plans for compliance with County ordinances and applicable State building regulations. Permitting Services offers traditional plan check, over-the-counter review, property-record research, and online permit applications for building, grading, solar, encroachment, transportation, pool, and other permit types. The County’s planning and development pages provide zoning codes, community plans, forms, and entitlement information for unincorporated property.

Inspections, code compliance, and occupancy

Inspection Services performs building, grading, subdivision, and encroachment inspections for permit activities in unincorporated Orange County. Use the County’s current online services and inspection instructions to request inspections and review project information; construction must comply with approved plans and current building codes. County permitting guidance explains that final inspection approval provides assurance that the permitted construction was performed safely and in accordance with State and local codes. A project inside an incorporated city must follow that city’s certificate-of-occupancy and inspection process instead.

Official contact information

The OC Development Services Permit Counter is at County Service Center, 601 North Ross Street, Santa Ana, California 92701. The published permit-counter phone is (714) 667-8888. Use the County’s official service-area pages for current hours, forms, permit searches, inspection requests, zoning resources, and the unincorporated-area jurisdiction boundary.

Field work & closeout

Building Inspections & Code Compliance in Orange County

Most permitted work must remain accessible for inspection at defined stages. Before scheduling, check your permit record for the required inspection sequence and make sure the site is safe and ready. Final inspections can be especially important for code compliance and a certificate of occupancy.

Helpful preparation

Keep the permit card or approval number available, confirm the property address, and ask the official office about lead times or reinspection fees.

Planning & review

Zoning and Plan Review Requirements

A building permit is not always the only approval your project needs. Zoning guidelines may affect use, setbacks, height, parking, signage, or lot coverage. Residential and commercial building permits can also follow different plan review tracks, so confirm the correct path before investing in a full plan set.

For a project in Orange County, start with the official department below and ask which zoning, planning, conservation, or fire review approvals apply to your address.
