Walkout Basements
Transform your basement into a light-filled walkout with direct landscape access — unlocking rental income, family space, and up to $70K+ in added property value.
Ready to Transform Your Basement?
A walkout basement conversion creates a full-height, ground-level entry from your below-grade basement to your backyard. BaseScape's Surgical Extraction Protocol carefully removes a section of your foundation wall, installs a structural header, and creates a code-compliant doorway — transforming trapped space into a light-filled, landscape-connected living area.
This isn't general carpentry. Cutting into load-bearing foundation walls is structural engineering. That's why BaseScape exists — it's all we do.
Utah ADU Compliance: The Stove Rule
Under Utah's HB 398 and SB 174, adding a full kitchen (with a stove) to a walkout basement can reclassify the space as an Accessory Dwelling Unit (ADU) — which is legal in most Wasatch Front cities but triggers additional building code requirements (separate utility metering, parking, fire separation). BaseScape helps you navigate this decision: convert for maximum rental income with full ADU compliance, or keep flexibility with a kitchenette configuration that avoids reclassification. We explain the trade-offs in plain language so you can make the right choice for your property.

Your Questions, Answered
Structural Safety
Every walkout conversion begins with a structural engineering assessment. We install steel or LVL headers rated for your home's specific load-bearing requirements. Your home is stronger after our work, not weaker.
Code Compliance
Full IRC compliance including egress requirements, structural engineering stamps, and city inspection sign-offs. We pull every permit and schedule every inspection.
Drainage & Moisture
Proper grading, French drain systems, waterproof membranes, and moisture barriers are built into every project. Water management isn't an afterthought — it's engineered from day one.
Dust & Disruption
Our dust containment system uses negative air pressure and sealed barriers to keep construction debris out of your living space. Most families stay in their homes throughout the project.
Cost & Affordability
Walkout conversions typically range from $50K-$100K depending on complexity. Financing options include construction loans with interest-only periods during the build phase. Most homeowners see ROI through rental income within 2-5 years.
Aesthetics
Your new walkout entry is designed to integrate with your home's architecture and landscaping. We work with your existing exterior finishes and landscape design to create a seamless transition.
Timeline
Most walkout conversions complete in 4-8 weeks depending on scope. We provide a detailed timeline at the engineering phase and keep you updated throughout.
