Multifamily Remodel
We specialize in transforming multifamily properties through strategic renovations that increase property value and rental income. Our team identifies underutilized spaces to add units or upgrade existing layouts while implementing energy-efficient systems that reduce long-term maintenance costs. Projects deliver measurable financial improvements including 77-140% rent increases and 50-151% ROI improvements for Seattle-area investors.
Building Evaluation
Our comprehensive evaluations assess multifamily properties for value-add opportunities including space utilization, system upgrades, and regulatory compliance. We provide detailed financial projections showing potential rent increases and ROI improvements from renovations. This includes identifying viable unit expansions, system replacements, and finish upgrades tailored to Seattle's rental market conditions.
System Upgrades
We modernize critical building systems including plumbing, electrical, and roofing to improve efficiency and reduce maintenance costs. These upgrades address aging infrastructure common in Seattle's 50-100 year old multifamily buildings. New energy-efficient systems lower utility bills while improving tenant comfort and property reliability through reduced service disruptions.
Unit Expansion
Our team reconfigures floor plans to maximize unit potential by adding bedrooms, bathrooms, and laundry facilities. We convert unused spaces like basements and common areas into income-generating units while optimizing layouts to increase marketability. These modifications create modern, desirable living spaces that command higher rents.
Exterior Renovation
We refresh building exteriors through painting, landscaping, and structural updates that enhance marketability. These improvements increase tenant satisfaction while attracting higher-quality renters willing to pay premium rates. Our designs consider Seattle's climate and urban environment to create durable, attractive facades that maintain value.
