Ensure your building has no objections

To ensure your building has no objections, you must abide by the rules and regulations set by the New York City Department of Buildings (DOB). Here are some key points to ensure your building has no objections during the conversion process:

• Approval from the Board: If you live in an apartment building, it is crucial to obtain approval from your Condo, Co-Op Board, or management company before proceeding with any renovations. All alterations must be approved by your building's board to avoid any potential objections.
• Permits and Certificates: In New York City, you typically need a permit to add a bedroom or change the number of rooms. Reach out to the DOB to understand the specific permits required for your project. Additionally, a Certificate of Occupancy (CO) is crucial for verifying the legal intended use and type of permitted occupancy for a building. Make sure to obtain the necessary certificates to avoid objections.
• Building Codes and Regulations: Familiarize yourself with the building codes and regulations for habitable rooms in New York City. These regulations include minimum room size, dimensions, window requirements, accessibility, and fire protection. By complying with these regulations, you can avoid objections based on non-compliance.
• Architect Involvement: Hiring an architect is essential to determine the legality of the work. The architect will be knowledgeable about New York City's building codes and can guide you through the process, ensuring that your conversion plans comply with all relevant regulations.
• Inspection and Sign-Off: Ensure that all required inspections are completed in a timely manner and that you obtain sign-offs from the necessary parties. This includes engaging with the DOB and/or the Special Inspection Agency (SIA) to ensure all required inspections are conducted. Addressing any objections raised during inspections is crucial to obtaining approval.
• Temporary Certificates: If your conversion project requires temporary measures, such as temporary construction or electrical work, you may need to obtain temporary sign-offs and permits from the DOB. Understanding the requirements for temporary certificates can help you avoid objections during the construction process.

By following these steps and working closely with the relevant authorities and professionals, you can increase the chances of ensuring your building has no objections during the conversion of a one-bedroom into two in New York City.

Check room requirements

When converting a one-bedroom into two in New York City, there are several room requirements that you must consider to ensure your project complies with local regulations. Here is a detailed guide to help you navigate these requirements:

Room Size and Dimensions:

• Minimum Room Size: Each bedroom must have a minimum size of 80 square feet. This applies to both new and existing rooms.
• Minimum Room Width: The width of the room should be at least eight feet in any direction. However, in apartments with three or more bedrooms, half of the rooms (rounded down) can have a minimum width of seven feet.
• Minimum Room Height: Ensure that the ceiling height is at least eight feet. For basement units, a ceiling height of seven feet is acceptable.
• Minimum Room Area: One room in the apartment must have a minimum area of 150 square feet. This is typically the living room.
• Exclusions from Floor Area: When calculating the floor area, do not include the space occupied by closets or wall thickness. Only consider net measurements, excluding gross measurements.
• Minimum Clear Space: The room should have a clear space of at least eight feet as its minimum dimension, considering both width and depth.

Window Requirements:

• Window Presence: Each room must have at least one window to provide natural light and ventilation. The absence of a window makes the room an "interior bedroom," which is illegal in New York City.
• Window Size: The window must be at least 12 square feet in size. This ensures compliance with natural light requirements.
• Window Glass Area: The total glass area of the window(s) should be at least 10% of the room's floor area. For example, a 200-square-foot room would need 20 square feet of glass.
• Window Height: Ensure that the top of the window is at least seven feet from the floor.
• Window Clearance: The window should have at least 30 feet of clearance in front of it. However, skylights may be considered in certain zoning districts.
• Window Operability: The window must be operable to allow for natural ventilation. When fully open, the open area of the window(s) should be at least 6 square feet and 5% of the room's floor area.
• Shared Property Line Windows: Windows on a shared property line do not count towards the window requirements unless you have a legal agreement with your neighbour, approved by the Department of Buildings (DOB).

Egress and Relationship to Other Spaces:

• Egress Requirements: For fire safety, there must be two means of egress or exit from the room. Typically, this can be achieved through a window and a door that can be accessed from the inside without keys or tools.
• Fire Escape Access: You cannot block the fire escape with any walls or obstructions. The bedroom can be accessed through the fire escape without issues.
• Room Accessibility: Each bedroom must be accessible without passing through another bedroom or bathroom. Each room should have its own entrance from a hallway or open living space.
• Smoke and Carbon Monoxide Detectors: Install hard-wired smoke and carbon monoxide detectors in each bedroom as per building code requirements.
• Electrical Outlets and Light Switch: Ensure there is at least one electrical outlet for every 12 feet of wall space. Additionally, provide a light switch for each bedroom.

Additional Considerations:

• Mezzanines and Split-Level Rooms: If the room has a mezzanine or split level, ensure that it is fully open for its full width, except for a railing. Such spaces are typically considered part of the room in which they are located.
• Temperature Requirements: All habitable rooms, including bedrooms, must maintain a minimum temperature of 68 degrees Fahrenheit.
• Kitchen and Kitchenette Differences: A kitchen is considered a habitable room and should be at least 80 square feet. A kitchenette, on the other hand, is not a habitable room and is usually smaller than 80 square feet.

Get a permit

To convert a one-bedroom into two in New York City, you will need to obtain a permit from the Department of Buildings (DOB). Here is a step-by-step guide to help you through the process:

• Hire an architect: The first step is to hire a registered architect who will determine the legality of the work and draw up the necessary plans. They will assess the property, take measurements, and ensure that your proposed conversion complies with all the applicable building codes and regulations.
• Understand the regulations: In New York City, there are specific regulations that govern the addition of bedrooms to apartments. These regulations include minimum size, dimensions, window requirements, accessibility, and fire protection standards. All habitable rooms must comply with these standards. Familiarize yourself with the New York City Building Code and the Multiple Dwelling Law.
• Get approvals from your building's management: Before submitting any plans to the DOB, you will need to get approvals from your Condo, Co-Op Board, or management company. They must have no objections to changing the number of bedrooms in your apartment. This step may involve providing detailed plans and specifications to the building's management for review and approval.
• File for an Alteration Type 2 permit: In most cases, adding a bedroom to an apartment will require an Alteration Type 2 (Alt 2) permit. This type of permit is applicable when you are making a renovation that does not change the Certificate of Occupancy. Your architect will typically handle the filing process, submitting the necessary plans and documentation to the DOB for review.
• Obtain necessary approvals and permits: Once the DOB has reviewed and approved your plans, they will issue the necessary permits for the construction work to commence. This typically includes a permit for the construction work itself, as well as any required electrical or plumbing work.
• Hire a licensed contractor: With your permits in hand, you can now hire a licensed contractor to carry out the conversion work. Ensure that your contractor is experienced in apartment renovations and familiar with the relevant building codes and permit requirements.
• Schedule inspections: During and after the construction process, you will need to schedule inspections with the DOB to ensure that the work complies with the approved plans and applicable codes. This typically includes inspections for electrical work and a final sign-off inspection.

Remember that converting a one-bedroom into two is a complex process that requires careful planning and adherence to New York City's building regulations. Always consult with qualified professionals, such as architects and contractors, to ensure that your conversion is safe, legal, and compliant.

Create a dividing wall

Creating a dividing wall to convert a one-bedroom into two is a feasible option, especially if you have a large bedroom. This process can take 2-3 days, depending on the specifications and requirements. Here are the steps you can follow:

• Dismantle and clear the area: If there are any existing structures or furniture in the way, temporarily dismantle and remove them to open up the space.
• Stud work: This involves creating the framework for the new dividing wall, using materials like wood or metal studs. Ensure the placement complies with the room size requirements in New York City.
• Insulation and electrical work: Install insulation within the stud framework to help regulate temperature and reduce noise transfer between rooms. Additionally, plan and install electrical sockets at this stage, ensuring they meet the electrical code requirements for residential spaces.
• Plasterboard and plastering: Attach plasterboard sheets to the stud framework, creating the solid surface of the new wall. Finish it off with a layer of skim plaster to smooth out any imperfections and create a seamless surface.

Remember to consult with professionals, such as architects and contractors, to ensure your plans comply with local regulations and are safe to execute.
