Sylmar homeowners often look for practical ways to expand living space without relocating. Whether you’re accommodating extended family, creating a private guest suite, or building a rental unit for additional income, a professionally constructed Accessory Dwelling Unit (ADU) offers a flexible and valuable solution. However, without experienced construction planning, projects can face delays, unexpected costs, or structural challenges.
