Questions

Basement Finishing FAQ

Basement finishing in San Diego typically costs $50-$75 per square foot for basic finishes and $75-$125+ per square foot for high-end build-outs. A 1,000 sq ft basement ranges from $50,000-$125,000 depending on features like bathrooms, wet bars, and custom finishes.
A typical basement finishing project takes 6-10 weeks from permit approval to completion. Complex projects with bathrooms, wet bars, or home theaters may take 10-14 weeks. We provide detailed schedules during consultation.
Yes, San Diego requires permits for basement finishing, especially for electrical, plumbing, and egress windows. Peak Builders handles all permits and coordinates inspections with San Diego Building Department to ensure code compliance.
An egress window is a code-required emergency exit window for basement bedrooms. San Diego code requires at least one egress window for any basement bedroom to ensure safe escape during emergencies. We handle egress window installation as part of bedroom conversions.
Yes, basement bathrooms are popular additions. If your home has a rough-in (existing drain connections), costs are lower. We can also install new plumbing lines if needed. Bathroom additions typically add $15,000-$30,000 to basement finishing costs.
We address moisture before finishing begins with proper drainage, waterproofing, and vapor barriers. San Diego's semi-arid climate helps, but we still test moisture levels and implement appropriate mitigation. All work includes moisture warranty protection.
