A comprehensive garage conversion includes: floor leveling and moisture barrier, insulation (walls, ceiling, floor), HVAC extension or new unit, electrical upgrades, egress window installation if required, interior finishing, and exterior modifications to remove the garage door opening. Berriz Design Build manages all components.

Garage conversions in Arlington typically range from $60,000 to $150,000 depending on size, existing conditions, and intended use (living space vs. ADU). Use our Pricing Guide for current ranges.
