Between our Elmhurst shop and the Westchester line. Apartments, co-ops and single-family houses, with the filing path settled before demolition.
The Bronx is the one borough where our work splits roughly evenly between apartment renovations and single-family houses, and the two run on different rules.
In a co-op or condo, the alteration agreement governs before the building code does. It is a binding contract between you and the board covering permitted work and required documentation, and each building writes its own. The wet-over-dry rule, boards prohibiting a bathroom, kitchen or laundry over a bedroom or living room below, is the most common reason a plan gets rejected. Board review runs from a few weeks to a few months depending on how often your board meets.
In a single-family or two-family house, there is no board, and the path is simpler: work altering plumbing, gas or electrical is filed with the Department of Buildings, generally as an Alteration Type 2 for interior work that does not change occupancy or structure. Approval commonly runs four to eight weeks after submission.
Either way the approvals sit ahead of demolition, not inside it.
The borough's residential stock runs from pre-war apartment buildings, with plaster over lath, cast-iron waste lines and tile set into mortar beds, to attached and detached houses in the northern and eastern neighborhoods, many of them mid-century or earlier.
The practical difference is what demolition uncovers. Pre-war construction is slower to take apart and reveals more than the drawings suggest; newer construction is more predictable but often tighter on original footprint.

Basements are worth noting here: unlike the borough's apartment stock, single-family houses often have full basements where egress becomes the deciding question for habitable use.
Board process for apartments, DOB filing for houses. We identify which applies before quoting.
Between our Elmhurst shop and the Westchester line, which shows up in scheduling.
NYC DCWP #2132-535-DCWP and Westchester County #WC-39446-H20-25, with $1,000,000 general liability.
One crew lead runs your project from demolition to final walk-through. Every trade, from plumbing to tile to finish carpentry, is coordinated through us, on our schedule, held to our quality standard. You never have to coordinate between separate companies.
It depends on scope, not on the borough. Work altering plumbing, gas or electrical is filed with the Department of Buildings, generally as an Alteration Type 2, the class covering interior work that does not change occupancy or structure, with approval commonly running four to eight weeks after submission. Replacing finishes in place often does not trigger a filing. We identify what applies at the estimate.
The board. Your alteration agreement is a binding contract between you and the building covering what work is permitted and what documentation is required, and it governs before the building code does. Board review commonly runs from a few weeks to a few months depending on how often your board meets, and it sits ahead of the DOB filing rather than beside it.
Wet-over-dry means placing a wet space (bathroom, kitchen or laundry) above a dry space such as a bedroom or living room in the apartment below. Most boards prohibit it, preferring wet stacked over wet so water exposure stays contained and riser access stays simple. It is the most frequent single reason an apartment renovation plan is rejected.
Often yes in a single-family house, and egress is usually the deciding question. The Residential Code of New York State requires an emergency escape and rescue opening with a minimum net clear area of 5.7 square feet for habitable basement space, and every basement sleeping room needs its own. Ceiling height, light and ventilation have to be met as well. We check all four at the estimate.
Yes. Kadima Construction holds NYC DCWP license #2132-535-DCWP and Westchester County home improvement license #WC-39446-H20-25, and carries $1,000,000 in general liability insurance. If you are in a co-op or condo, your board will typically require a certificate of insurance naming the building and managing agent as additional insured. Send us their required format with the estimate request.
Tell us whether you are in an apartment or a house and we will tell you which approval path applies before anything is drawn.
