What DIY Improvements Are Allowed or Not Allowed Inside Your Co-op? There’s a Distinction Between ‘Decorating’ and ‘Renovating’


Like any homeowner, co-op owners are always planning improvements to their homes.  But one major difference between a cooperator and a homeowner is that the cooperator just can’t do whatever and whenever he/she wants.  For example, if if the co-op owner renovates a bathroom, he or she runs the risk of flooding the downstairs neighbor. Oftentimes any work requires notification and approval of the board.  With that in mind, when can a shareholder feel free to act and when should they notify and seek the permission of the board and corporation to alter their home?

Decorating Versus Renovating

Ray Levy, a board member at a pre-war co-op in Washington Heights, points out that his building doesn’t have a hard distinction about what kind of work requires board approval. “Decorating versus renovating is the guiding principle behind the board’s monitoring of shareholder work,” he says.  So if a shareholder is planning on painting a bathroom themselves, that clearly falls under the category of decorating.  But if the same shareholder is planning on removing fixtures and tile work, particularly when plumbing or electrical work is involved, it’s a renovation, and would require filing an alteration agreement and getting board approval.

Are You Painting, or Are You Hiring a Painter?

DIY, in many cases, has to be exactly that: ‘do-it-yourself.’  Once you hire someone, even for something as innocuous as a coat of paint, the picture changes.  

“Each co-op building is different,” says Deborah Koplovitz, a co-op and condo attorney with Anderson Kill, a law firm located in Manhattan, “and you have to look at those documents carefully. Six words to live by: ‘lease by lease,’ ‘board by board.’ The most general concept is that board consent is usually required to alter an apartment. Painting may not be an alteration, or in the view of a board it may be.  There are buildings that require alteration agreements for painting, and those that make sure at a minimum that the workers have insurance and that the co-op is added as an additional insured on that insurance policy. To do that, at least one agreement is required and likely two, even if not a full-blown alteration agreement. So a building may want the standard alteration agreement signed.  

“It’s also important to note,” she adds, “that some proprietary leases say that the co-op’s consent to renovations/alterations cannot be unreasonably withheld. In the event a shareholder in such a case disagrees with a board’s decision, that decision would be subject to the court’s oversight and scrutiny.”

  • Its interesting. Living in my co-op you wouldn't know it that this information is true. At my co-op people do what ever the hell they want without any permission. What ever work happens in an apartment is a secret from everyone else. One new buyer took it upon himself to put an awning above his window and put a different design and color of handrails from the others. Everything goes, I guess until someone will gets hurt or there will be serious damage
  • My co-op is pretty liberal minded when it comes to decorating and renovating. Anything that is not structural in nature doesn’t need board approval. If you wanted to replace your cabinets, countertops or flooring, you’re in your right to do so with authorization. I removed my tile around my tub surround without permission. If I were to have replaced the faucet fixtures, I would have needed permission. Something as simple as changing a light fixture, needs board approval. I changed all my light fixtures in my two bedroom unit without asking for permission. My co-op generally wants owners to ask for permission if it’s dealing with plumbing, electrical, foundation and roofing. Other than that, you can paint your apartment any color you want on the inside.
