Common Questions

Frequently Asked Questions

Do I need a permit to finish my basement in NYC?

Yes. Any basement remodel involving electrical, plumbing, egress windows, or converting the space into habitable/rental space requires DOB permits and inspections; we handle the filing process for you.

What ceiling height do I need for a legal basement conversion?

NYC Residential Code generally requires at least 7 feet 6 inches of finished ceiling height for habitable basement space, with some allowance around beams — underpinning can help older homes meet this.

Will my basement flood after it's finished?

Not if it's waterproofed first. We install interior drainage, sump pumps, and exterior sealing before any finishing work so your investment stays protected.

How is a "basement" different from a "cellar" for legal apartment purposes in NYC?

A basement (partly above grade) can be legalized as a rental unit more easily than a cellar (fully below grade); we assess your space and guide you through what's legally possible.

How long does a basement remodel take?

A standard finishing project runs 4-8 weeks; apartment conversions or underpinning projects can take 3-4 months due to permitting and structural work.

Can you add a bathroom to my basement?

Yes — we regularly install ejector pumps and up-flush systems that let us add full bathrooms even in basements below the main sewer line.

Do you handle mold or water damage before remodeling?

Yes, remediation and moisture control are built into our process before any framing or finishing begins.
