HUD, FHA & VA Compliance

Buying, selling, or refinancing a manufactured home with an FHA, VA, or conventional loan? Your lender will almost certainly require a HUD-compliant tie-down system and a licensed engineer's certification before the loan can close. We handle both — fast.

Washington State law independently requires manufactured homes to be secured with approved anchors and tie-downs. Homes built after October 20, 2008 must meet current HUD anchoring standards under CFR Part 3285. Older homes may need to be brought up to current standards as a condition of loan approval.

🏦

FHA & VA Loans

FHA and VA loan underwriters require manufactured homes to have tie-downs installed and certified by a licensed engineer. We provide the installation and documentation your lender needs to close.

📄

Engineering Certifications

We provide HUD-compliant engineering reports certifying your tie-down system meets the Permanent Foundations Guide for Manufactured Housing (HUD-007487). Escrow payments accepted.

⚖️

Washington State Law

WA State requires manufactured homes to be anchored per HUD standard CFR 3280. Our installations meet or exceed state requirements, completed by a licensed installer (CHEWNLW863C6).

We provide Western Washington manufactured home owners with professional services that meet HUD standards — securing your investment against wind, seismic activity, and moisture.

Featured System
Seismic & Wind Protection

ERB / Xi2 Foundation Systems ERB

Earthquake Resistant Bracing (ERB) using Xi2 technology keeps manufactured homes stable during earthquakes, windstorms, and soil movement. Xi2 uses rigid steel struts — rather than old-style straps — to control uplift, lateral, and longitudinal forces simultaneously.

Especially well-suited for Western Washington, where seismic activity and saturated soils require a stronger, longer-lasting anchoring solution than traditional strap-based systems.

ComponentPurpose
Lateral StrutsPrevent side-to-side movement during wind or seismic activity
Longitudinal StrutsPrevent front-to-back shifting; replace end frame ties
LSD Hardware KitsConnect struts to I-beams and anchors
Ground/Concrete AnchorsSecure the system to soil or concrete foundation

Rigid 4-Way Hold

Controls uplift, lateral, and longitudinal forces simultaneously, unlike traditional strap tie-downs that resist only certain directions.

HUD-Approved & ERB Certified

Meets federal Earthquake Resistant Bracing requirements. Works in soil rated 4B (175–275 lbs) or better. Homes up to 48 inches above grade.

Works on Any Foundation

Compatible with soil, concrete slab, or steel pier foundations. Suitable for frost heave or shifting ground, common throughout Western Washington.

Reduced Hardware Needs

Often eliminates stabilizer plates and diagonal frame ties. Simpler installation, fewer long-term maintenance points.

Galvanized Steel Construction

Telescoping galvanized steel struts resist corrosion in the wet Pacific Northwest climate — built to outlast traditional strap systems,
