Manufactured Home

Introduction

Manufactured homes are permitted as residences primarily within designated manufactured and special occupancy parks, or public camping areas, in accordance with Humboldt County Code 314-81.1 and the Health and Safety Code of California. They may also be located outside these parks in specific zoning districts where such use is authorized. When installed outside of parks, manufactured homes must comply with standard building and zoning regulations, which include being enclosed with skirting at ground level, and, depending on the home’s manufacture date, may require attachment to a permanent foundation or meet other specific safety standards.

Key Points

1. Location and Use: Manufactured homes are primarily designed for residence within manufactured home parks and special occupancy parks. They can also be situated in certain zoning districts where their use is explicitly permitted outside these parks.
2. Compliance Requirements: When placed outside of parks, manufactured homes must adhere to the same building and zoning regulations as standard buildings used for similar residential purposes.
3. Documentation and Approvals:
   • The insignia certifying approval for wildfire hazard areas shall be provided for installations in State Responsibility Areas.
   • A 433A Form will be required to be recorded with the California Department of Housing and Community Development after construction is complete.

Construction Requirements

• Foundational Requirements: Depending on the age of the manufactured home, it may need to be placed on a permanent foundation or equipped with a standard setup that includes tie-down anchors.
  • The home must be enclosed at ground level with appropriate skirting, except for necessary venting.
  • Homes manufactured before September 15, 1971, may be placed on a permanent foundation if certified structurally sound by a licensed engineer and compliant with the Uniform Building Code.
  • Homes sold before July 1, 1980, must be attached to a permanent foundation as approved by the Chief Building Inspector.
  • For homes sold on or after July 1, 1980, attachment to a permanent foundation or a standard setup with approved tie-down anchors is required.
• Engineering Certification: Older homes, specifically those manufactured before 1971, require a certification from a licensed engineer to verify that they meet current building codes and are structurally sound.
