Requirements of Many Public Funding Sources
Grant-funded mobile home and manufactured housing projects in California—whether through state programs like Homekey+, HOME, CDBG, PLHA, or federal programs—frequently trigger prevailing wage and apprenticeship requirements.
For nonprofits, housing authorities, and cities, these requirements can seem daunting—especially because mobile home installation does not fit neatly into traditional construction categories.
The good news is that with proper planning and compliance systems, these requirements are entirely manageable.
Prevailing wage is the mandated minimum hourly pay, plus benefits, for workers on publicly funded construction projects. Regulation occurs at two levels: at the State level in California, governed by The California Labor Code (Public Works laws) and overseen by the Department of Industrial Relations (DIR), and at the Federal level, regulated by The Davis-Bacon Act.
Prevailing wage is generally required when public funds are used, the project qualifies as “public works,” or the funding source mandates it, even if not legally required. For mobile home projects specifically, prevailing wage is commonly triggered when State grants (e.g., HCD programs, PLHA, Homekey+) or Federal funds (e.g., HOME, CDBG, ARPA, HUD) are involved, or when a public agency owns or controls the project.
State and Federal prevailing wage requirements are two separate items. They may apply together or only one may apply. This depends on the funding source.
Prevailing wage and apprenticeship requirements apply when a project uses state funding and qualifies as public works under the California Labor Code. These requirements are administered by the California Department of Industrial Relations (DIR). Key features include wage rates that are often higher than many federal wage determinations, strict certified payroll submission requirements, and mandatory apprenticeship participation.
The Federal Prevailing Wage applies when federal funds are used or when required by specific HUD or other federal programs, and it is administered by the U.S. Department of Labor (DOL). Key differences include that wage determinations are issued by county, labor classifications may differ, and certified payroll is typically submitted through federal reporting systems or to the funding agency.
One of the most common questions is:
“What labor classification applies to mobile home installation?”
There is no specific “mobile home installer” classification under California prevailing wage. Instead, contractors must determine the closest applicable trade based on scope:
Here is the classification we have used in a mobile home installation project:
|
Task |
DIR Labor Classification |
|
Block & Level & Set |
Laborer Group 3 - Construction Laborers |
|
Install/upgrade electrical pedestal |
Residential Electrician |
|
Grade the lot |
Operator Engineer - Group 5 - Loader under 4 cu yds |
|
Water & Sewer Connection Installation |
Plumber |
|
Gas connection |

|
Skirting |
Residential Carpenter |
|
Electrical Installation |

|

Proper classification is critical. Misclassification can lead to back wage liability, penalties, and funding risk. Experienced labor consultants are strongly recommended for classification analysis.
Wage rates, which are published by the Department of Industrial Relations, are county-specific and trade-specific, and they are updated twice per year. These wage determinations include the base hourly wage, fringe benefits, and overtime and holiday rates.
Federal prevailing wages, published by the U.S. Department of Labor, are county-based and specific to the type of construction (building, heavy, highway, or residential); therefore, it is critical to verify which construction type applies to your mobile home project.
Certified Payroll Records (CPRs) must be submitted weekly through the DIR Public Works Online System, requiring contractor registration with DIR and accurate classification reporting. Failure to submit CPRs can result in penalties and funding issues.
Certified payroll is typically submitted to the funding agency (e.g., city, county, housing authority) or through systems required by HUD or the administering entity.
For public works projects in California, contractors are required to hire apprentices for applicable trades. This is distinct from prevailing wage requirements. They include:
Employing apprentices who are enrolled in state-approved programs.
Making contributions to apprenticeship training funds.
Apprenticeship is generally required when the project is subject to California prevailing wage, the contractor is awarded a contract over $30,000 for the project, and the trade has an approved apprenticeship program.
California typically requires 1 hour of apprentice work for every 5 hours of journeyman work (approximate 20% ratio). There is no minimum number of hours. Apprentices, however, may not be available for a small number of hours.
If apprentices are unavailable after proper request, documentation is critical to avoid penalties.
Contractors must ensure the proper utilization of apprentices, who are requested through California DIR-approved apprenticeship programs. The contractor's responsibilities include submitting the DAS 140 (Notice of Award), submitting the DAS 142 (Request for Apprentices), and keeping records that prove the request for apprentices was made.
Mobile home installation presents unique labor compliance challenges because the work is factory-built and only site-installed, meaning apprenticeship is required only for onsite work like lot improvement and home installation. Unlike traditional building contractors, installation crews are often highly specialized, and there is no direct apprenticeship for mobile home installation itself. Instead, setup, skirting, and utility hookups fall under different trades, requiring the search for apprentices in similar trades (such as a Laborer, which is an apprentice trade).
These labor compliance issues, including prevailing wage and apprenticeship requirements, must be addressed early in the processes of budgeting, contractor bidding, and grant application, as failing to account for them can materially affect a project's feasibility.
