Key Considerations Before Starting a Home Conversion

Evaluating Your Home's Potential for Conversion

Given Des Moines' unique topography that slopes down to Puget Sound, we recommend starting with a professional structural assessment. The foundation, load-bearing walls, and existing systems require careful examination, especially in homes near the waterfront.

Space configuration plays a crucial role in successful residential conversions. Many Des Moines homes offer excellent conversion potential due to their elevation, allowing for walkout basements and stunning water views.

Key areas to evaluate:

• Structural integrity, particularly important in our marine environment
• Electrical capacity
• Plumbing access
• HVAC requirements for our variable climate
• Emergency exits
• Sound insulation, especially near Seattle-Tacoma International Airport

Navigating Zoning and Legal Requirements

As a city incorporated in 1959, Des Moines has specific building codes and zoning requirements. We're particularly experienced with:



• Properties within airport noise zones
• Waterfront property regulations near the 838-berth marina
• Saltwater State Park adjacent properties
• Areas near Highline College and the upcoming Light Rail station (2026)

Setting a Realistic Budget

The budget forms the foundation of any conversion project. In Des Moines, where property values have seen significant changes and the housing market remains competitive, we help clients create detailed cost estimates that include materials, labor, and permits.

Essential budget components:



• Materials: 40-50% of total cost
• Labor: 30-35% of total cost
• Permits: 5-10% of total cost
• Contingency: 10-15% buffer
