Aliso Viejo building permits run through the CSS portal
Aliso Viejo uses the CSS portal for building permit applications and inspection scheduling, while business registration questions may need Planning review before filing.
Aliso Viejo building permit work goes through the CSS portal. That account is used for permit applications and for scheduling inspections tied to a permit.
The building side covers common building, mechanical, electrical, and plumbing permit types. If the question is about a form outside building work, the city’s forms and permits directory is a better map. It separates building, code enforcement, planning, environmental services, financial services, and other city needs.
For a business registration, the form tells applicants to contact Planning before submitting so the city can check the zoning district. Some uses may need an extra permit, and some may not fit the location.
Start with the address, project type, contractor contact, business activity if one is involved, and any floor plan or product information. For inspections, make sure the permit record is active before trying to schedule.
