Basement remodeling timeline and permits
Finishing a storage basement typically takes 2–3 weeks. A family room or office with bath usually runs 4–7 weeks. An attic conversion or full basement with structural, electrical and HVAC upgrades is often around 6–10+ weeks depending on approvals and material lead times.
NYC projects can require permits for structural work, egress, plumbing, electrical, HVAC and insulation. Our team prepares documents, submits filings and coordinates inspections with the NYC Department of Buildings and building management where needed.

Small NYC basements and attics
In tight NYC basements and attics we focus on headroom, egress and storage. Low-profile ductwork, storage under stairs, shallow built-ins and light finishes keep the space open. Continuous flooring and simple trim help connect zones. Where house rules allow, we add an egress window or adjust door swings to improve movement while staying within code.
