For a Riverside County manufactured-home installation, match the foundation type to the final document: an Installation Acceptance or a manufactured-home Certificate of Occupancy (CO). The County’s current installation guide distinguishes these from utility-connection tags. Start with the installation permit and inspection history, then request the matching final record. Permit issuance alone does not show final approval.
This route is for records issued by Riverside County Building and Safety. The County describes its construction-approval role in unincorporated areas in its 2025–26 adopted budget. If the site is inside an incorporated city, verify the issuing office on the permit before treating an empty County search as a missing installation. Our city-versus-county record guide explains this first jurisdiction check.
Find the installation permit, then read its inspections
The County’s Records Request page directs a searcher to Map My County. It says the parcel report accepts a single APN, multiple APNs, or an address. Open “full report for this parcel” and scroll to “Building and Safety Cases” for the permit list; a blocked report pop-up is a display problem, not a no-record result. Save the parcel identifier, the installation-related permit number, its description, and any other site-preparation or foundation-system permit number shown. A parcel can have several projects, and the first permit on the list need not belong to the home at issue.
With a permit number, use the County’s Online Services page: Building Permit Information and Building Permit Inspection History have separate permit-number inputs. Its Cases / Permits by Assessor’s Parcel Number box accepts a nine-digit APN when you need another permit-number lead. The Records Request page says permits issued after 1997 can be viewed or printed online through Building Permit Information, with inspection history checked separately. That is a stated online permit route, not a promise that a signed final certificate or every older attachment is downloadable.
Compare the installation permit’s site address, APN, work type, and inspection dates with the home you are researching. The County guide separates the utility site-preparation permit from the installation permit. If you find only a utility permit or an issued installation permit, keep searching for the installation’s recorded final result. Our final-inspection status guide helps distinguish a scheduled or partial inspection from a passed final.
Ask for the final document that fits the installation
The current Forms page links Form 284-017, Manufactured Home Installation Guide. Its linked PDF states Revised 6/2024. On its final-inspection page, the County makes three records easy to confuse:
- Installation Acceptance: the guide’s certificate left for a manufactured home not on a permanent foundation after the final inspections pass.
- Manufactured Home Certificate of Occupancy: the guide’s final certificate for a home on a permanent foundation after those inspections pass.
- Acceptance Notice tags: posted at the electric service panel for electric and gas service connections. They answer a service-connection question, not by themselves which final certificate was left.
For a hypothetical file containing both a utility permit and an installation permit, make two separate notes: what each permit covers, and which inspection belongs to it. If the only final entry relates to the utility work, request the installation’s own final record. Use the County file’s foundation classification to choose the document; do not infer it from a photograph.
When the online history ends before the file does
For an older or incomplete result, the County’s archived-record request requires at least the address or APN. Provide both if known, plus approximate year, the installation and site-preparation permit numbers, and the precise item sought: the installation permit, final inspection entry, Installation Acceptance, or manufactured-home CO. The Records Division lists 951-955-2017 for questions; copy and research charges may apply. Keep the response with the identifiers used, especially if staff corrects a permit number or finds a separate final document.
The County reports permit holdings from approximately 1963, with earlier building permit records destroyed. That is a holdings limit, separate from the post-1997 online route. Ask staff whether the specific final document survives in the installation file. If only general property-history material is available, label it as background; it cannot supply a missing final certificate.
An empty County search does not prove that no installation permit, final inspection, Acceptance, or CO exists. Address variants, a different APN or permit number, an archived file, and the issuing jurisdiction can change where to look. Preserve the dated County record and ask the issuing office to resolve the specific gap.
