About each permit

Business (Stormwater) Registration

Every business physically located or operating in the unincorporated area of Riverside County — including a mobile business and a state-licensed contractor — must register under Ordinance 857.1, even categories that pay no fee: home occupations conducted entirely by phone, mail or internet with no stormwater impact, non-profits, agricultural operations, churches and residential-care facilities all still must register within 60 days of notification. The first-year registration fee is $45, annual renewal is $30, a change of business name or location is $30, and a duplicate registration certificate is $10 — these are the complete fee components, not tiers that stack. This registration applies only in the unincorporated area; a business inside any of the 28 incorporated cities instead checks that city's own business-license ordinance and does not need this county registration. It is a stormwater-compliance registration, not a general business license, and confers no separate operating authority.

Contractor Licensing — State CSLB License Applies (Riverside County)

No fee applies at the county level. The County's Business Licenses and Permits page lists no contractor license among its county permits; a contractor's core credential is the California Contractors State License Board (CSLB) license, recorded at the state layer. A contractor working in the unincorporated area of Riverside County still must obtain the county's own Business (Stormwater) Registration in addition to, not instead of, its CSLB license — the registration's own guidance materials explicitly tell state-licensed contractors this. A contractor performing road work in the county right-of-way may also need a Transportation Dept. permit; the fee for a routine standalone encroachment permit is not shown here, while a road-improvement plan-check fee tied to Ordinance 348 land-use applications ('greater of $500 or 6.5% of estimated cost of construction') applies in that narrower scenario.

General Business License — Riverside County position

No fee applies. Riverside County's own 'Business Licenses and Permits' page frames county licensing as a set of activity-specific permits issued by separate departments — Planning, Building & Safety, the Agricultural Commissioner, Transportation, Environmental Health and the Sheriff's Department — rather than a single general license, and it refers general business-licensing questions to the California Dept. of Tax and Fee Administration. The closest county-level analog for a business physically located in the unincorporated area is the Business (Stormwater) Registration (recorded separately below), which is a registration, not a license, and does not authorize any specific activity. All 28 incorporated cities in Riverside County run their own separate business-license programs, which are not covered on this county page. A business inside an incorporated city should check both this page and its city's requirements.
