Room Additions in Queens
In Queens, 37% of owner-occupied homes are detached houses, and with attached and two-family houses they are where additions happen; apartment owners cannot add floor area. Dormers, rear extensions and second-floor additions are the usual options, each starting with zoning, the existing structure and a Department of Buildings filing. Goodhaus does not do the work; it is a free service that puts owners in touch with independent contractors.

Room Addition Ideas to Consider in Queens
General ideas for inspiration only. These are not projects performed by Goodhaus, which is a free matching service and not a contractor.
Dormers and second floors
Building up depends on the existing structure and the zoning limits; check both with an architect or engineer first.
File before building
In New York City, construction without Department of Buildings approval or permits is illegal, and the work must be legalized or removed.
Weekend work
New York City allows alterations to an owner-occupied one- or two-family home on Saturdays and Sundays from 10:00 am to 4:00 pm, if the house is more than 300 feet from a house of worship.
Costs
How much does a room addition cost in Queens?
Queens addition quotes depend on structure, foundation, the roof tie-in, access on a dense block, the engineer's or architect's filing and the trades required.

What licence should an addition contractor have?
