Mixed-Use Properties

A mixed-use property combines residential apartments with commercial or retail space in the same building, the classic New York arrangement of a ground-floor storefront with apartments on the floors above. It is one building with a single roof and shared building systems, but the residential units and the commercial space are governed by different rules on leases, tenant protections, and what a landlord can and cannot do. A buyer, seller, or owner has to account for both sets of rules at the same time.

Fisher Stone represents buyers, sellers, and owners of mixed-use buildings across New York City, from a small building with one ground-floor shop to a larger property with residential units above several commercial spaces. A licensed New York attorney handles your purchase, sale, or ownership matter from start to finish, reachable directly by call, email, or text, for a flat fee, quoted up front, after a short, free consultation of about 15 minutes.

One building, two legal regimes

The commercial space, whether a retail storefront, a restaurant, or an office, is largely governed by the lease the landlord and tenant negotiate. New York law places some limits on commercial leases, but the parties otherwise have wide latitude to set the rent, the term, the permitted use, and each side’s obligations to the other.

The residential units work differently. State and city law give residential tenants protections that a landlord and tenant cannot sign away in a lease, on matters such as notice before a tenancy can be ended and the habitability of the unit. Depending on the building and its rental history, some units may also be rent regulated, carrying further protections of their own. A mixed-use purchase draws on both sides of Fisher Stone’s real estate practice at once.

Financing a mixed-use purchase

Financing a mixed-use property does not work like financing a single-family home or a condo. Most lenders treat it as a commercial transaction, even when most of the square footage is residential apartments. Rather than underwriting the loan mainly around the borrower’s personal income and credit, a mixed-use lender looks closely at the income the building produces from both sets of tenants, and at the mix between them.

How a lender weighs that mix and the building’s income varies, and the specifics depend on the lender and the deal, including location, the tenants in place, and the buyer’s plans for the space. Some conventional residential lenders decline mixed-use buildings altogether, or cap how much commercial space they will accept, which is why buyers often work with lenders who specialize in these properties. Fisher Stone coordinates with your lender to keep financing on the same timeline as the rest of the closing, and separately represents banks and private lenders financing New York property.

Zoning, permitted use, and the certificate of occupancy

Every building has a certificate of occupancy stating the number of dwelling units and the permitted use of the non-residential space, and the building’s actual use needs to match what that certificate allows. This matters more in a mixed-use building than a single-use one, since the commercial space and the residential units can each raise their own zoning and use questions.

A common risk in a mixed-use purchase is a commercial use that was never properly legalized. A storefront might be operating as a restaurant, a gym, or another use requiring its own permits or a certificate of occupancy amendment the current or a prior owner never obtained. Buying a building with an unlegalized use can mean inheriting the cost of bringing the space into compliance, or being unable to continue or replace that tenant’s use. Before signing a contract, your attorney reviews the certificate of occupancy against the actual use of the whole building, and checks for open violations tied to the use question.

Two lease worlds under one roof

A mixed-use building runs on two different kinds of leases at the same time, and the rules that apply to one do not carry over to the other.

The commercial space

The lease for the retail, restaurant, or office space is a negotiated contract. The landlord and the commercial tenant are largely free to set the rent, term, permitted use, renewal options, and who is responsible for repairs and improvements. A commercial tenant’s rights to renew, sublease, or alter the space depend on what the lease says, which is why reviewing it carefully, on both sides, matters before a sale or a new lease is signed. See our commercial real estate page for more on how those leases are typically negotiated.

The residential units

The residential leases work differently. New York law gives residential tenants protections, on matters such as notice and the grounds for ending a tenancy, that a lease cannot override regardless of what the landlord and tenant agree to in writing. Depending on the building’s size, age, and rental history, some residential units may also be rent regulated, adding further protections beyond an unregulated apartment. A buyer needs to know, before closing, which protections apply to which units, since that shapes what the new owner can do with those apartments going forward.

Due diligence before you buy

Due diligence on a mixed-use purchase has to cover the residential and commercial sides separately, since a clean picture of one does not tell you much about the other. Before you sign a contract, your attorney’s review typically includes:

• The leases and rent roll for both the residential units and the commercial space, including rents, terms, and renewal dates
• Security deposits held for each tenant, and whether they have been properly maintained
• Any rent or other charges owed by residential or commercial tenants in arrears
• Open violations from the city, and any open permits that have not been signed off
• The condition of the building’s systems, such as the roof, boiler, electrical, and plumbing, which are shared by every tenant
• Any commercial tenant’s rights to alter, sublease, or assign the lease, which can limit what a new owner is able to do with that space

Reviewing both rent rolls together also shows how much of the building’s income comes from each side, information the lender will also want when underwriting the purchase.

Operating and selling a mixed-use building

Running a mixed-use building means dividing certain costs between the residential and commercial portions rather than treating the building as one expense. Property taxes, insurance, and utilities often need to be apportioned between the two, whether that split is set out in the leases, handled through separate metering, or allocated by the owner based on use. Getting that apportionment right, and documenting it clearly, avoids disputes with tenants and makes the building easier to sell, since a buyer’s attorney will ask how those costs have been divided.

Selling a mixed-use property involves the same kind of review a buyer would run, from the seller’s side. Having the leases, rent roll, violation and permit history, and records of how taxes, insurance, and utilities have been divided organized and ready moves a sale forward and heads off questions once the deal is under contract. Fisher Stone represents owners on both ends, preparing a property for sale as well as handling the purchase.
