❓Common Questions

According to the 2022 NYC Building Code, habitable rooms in basements must have a minimum ceiling height of 7 feet 0 inches. Spaces with lower ceilings may only be used for storage or utilities.

Under Local Law 128, the DOB base permit fee is $130 for the first $5,000 of construction, plus $13 for every additional $1,000. Soft costs for expediters and architects typically add 10-20% to these fees.

Installing a code-compliant egress window in NYC typically costs between $3,500 and $8,000. This includes foundation cutting, structural lintels, and the required window well with proper drainage.

Homeowners can expect a resale value recoup of 50% to 65% on average. However, in high-demand areas like Staten Island, permitted basement finishes can return up to 95% of their direct hard costs.
