The Step-by-Step Guide to Preparing Land for a Manufactured Home
So you’ve found the perfect piece of land for your manufactured home — congratulations! Now comes the part that truly sets the foundation (literally) for a smooth setup: land preparation.
Proper site prep is one of the most important steps in ensuring your home is safe, level, and built to last. Whether your property is in Santa Rosa, Healdsburg, or the hills of Sebastopol, this guide walks you through each stage of preparing land for a manufactured home in California, with insights specific to Sonoma County.
Step 1: Evaluate Your Property
Before any dirt is moved, you’ll need to assess your land’s suitability for a manufactured home.
Here’s what to check:
Zoning regulations: Confirm that your land is zoned for manufactured housing. Sonoma County zoning maps and the Permit & Resource Management Department (PRMD) can confirm this.
Accessibility: Your home delivery truck needs clear, stable access. Steep driveways or tight corners may require grading or trimming.
Utilities: Check if your land already has power, water, and sewer — or if you’ll need new connections or a septic system.
✅ Pro tip: Before purchase or setup, schedule a site evaluation with a local contractor. They can flag issues like slope, drainage, or soil composition early — saving you from costly surprises later.
Step 2: Clear and Grade the Site
Once your site is approved, the next step is clearing and grading.
This includes:
Removing trees, brush, and debris
Leveling the pad area for your home
Ensuring proper water drainage away from the home
In Sonoma County, drainage is especially important — our clay-heavy soils can hold water during the rainy season. Grading should direct water away from the home’s base to prevent future issues.
Step 3: Soil Testing and Foundation Planning
Next comes soil testing, which determines what kind of foundation your home will need. A geotechnical engineer or your contractor will test for:
Soil compaction and bearing capacity
Water table depth
Potential erosion or slippage risks
Based on results, you’ll choose between a pier and anchor system, permanent foundation, or slab setup — each with different costs and installation timelines.
Step 4: Secure County Permits
Before breaking ground, you’ll need the right permits from Sonoma County.
Typical permits include:
Grading permit (if moving soil or changing elevation)
Building permit (for foundation and setup)
Septic permit (if applicable)
Electrical and plumbing permits
Your contractor can help handle paperwork and coordinate inspections. The Sonoma County Permit & Resource Management Department provides online resources to track approvals.
Step 5: Install Utilities
A manufactured home site needs access to power, water, and waste management before the home arrives. Depending on your property:
Electricity: Connect to the local grid or install a new pole and meter.
Water: Hook up to a city system or install a well.
Septic/sewer: Install or connect to a system that meets local environmental standards.
These connections must pass inspection before your home is placed.
Step 6: Prepare the Foundation Pad
Once utilities and grading are complete, it’s time to prepare the foundation pad.
This involves:
Compacting soil or gravel to prevent settling
Setting concrete piers, runners, or a slab
Verifying measurements and elevations match your home’s layout
A properly built pad ensures your manufactured home sits level, stable, and secure — preventing long-term issues like cracks or uneven flooring.
Step 7: Final Site Inspection
Before delivery, Sonoma County requires a final pre-installation inspection. This confirms that:
The site is properly graded
Utilities are ready
The foundation meets code
Once you’ve passed inspection, your property is officially ready for home delivery and setup — the most exciting step in the process.
🌿 Why Local Experience Matters
Every piece of land in Sonoma County is unique — from the sandy soils near the coast to the rocky hillsides in wine country. Working with a local manufactured home setup company ensures:
Your site meets local zoning and soil standards
Permits are submitted correctly the first time
Setup is planned around seasonal weather patterns
That local knowledge can mean the difference between delays and a smooth, on-time installation.
