Codes and permits

Finished basements are new living space, so permits and inspections are generally required. Sleeping rooms need code-compliant egress. Smoke and carbon monoxide alarms, fire-blocking and electrical requirements also apply. We confirm current requirements with your city building department.

Planning tips

• Keep mechanical equipment accessible with a door or service panel.
• Plan lighting carefully since basements get little daylight.
• Use moisture-tolerant flooring such as tile, engineered wood or luxury vinyl plank.
• Add sound insulation in the ceiling if bedrooms are above.
• Think about storage you will lose and plan for it in the new layout.

Basement finishing FAQs

Can I add a bathroom if there is no rough-in? Usually, but it may require cutting the slab and possibly a pump system. We assess this during the estimate.

How long does it take? Most basement finishes take several weeks of work plus time for inspections, depending on size and whether a bathroom or kitchenette is included.
