Mixed-use buildings

A mixed-use building puts a business space (a shop, cafe, office or studio) and one or more homes in the same building. Usually the shop is on the street floor and the apartments are above. Many owners are ‘owner-operators’ who run their own business downstairs and live upstairs, which cuts out a commute and a second rent or mortgage.

It’s really two investments in one. The homes behave like ordinary rentals, but the storefront depends on foot traffic, the local economy and finding a business tenant, and commercial space can sit empty for years. In San Francisco, the Chronicle found 17 vacant storefronts (about 45 percent) in 20 new buildings near Market Street in 2017, even though the apartments above were built and rented.

Financing and rules are mixed too. Fannie Mae will back a home loan on a one-unit home with a business space only if the borrower lives there, owns and runs the business, and the property is mainly residential. Larger buildings with a storefront and several apartments usually need a commercial loan. Zoning, building codes and insurance also have to allow both uses.

Who it suits

Small-business owners who want to live where they work and stop paying separate rent for a shop or studio.
Buyers who already understand both residential and small commercial leasing, or who will run the storefront themselves.
Long-term holders in walkable town centers and older main streets where shops on the ground floor are normal.
People who like being part of street life and don’t mind customers and neighbors knowing their routine.

Who it doesn’t

Buyers counting on the storefront rent to cover the mortgage. Commercial space can stay empty for years.
People who need a standard home loan on a larger building. Most mixed-use buildings with several units need commercial financing.
People who value privacy and quiet. Living above a bar, cafe or shop means noise, odors and little separation from work.
First-time investors who have never handled a commercial lease, build-out or business tenant.

Real stories

Bar downstairs, home upstairs for decades (2005)

A couple bought a 203-year-old brick rowhouse in Baltimore’s Fells Point and opened a Scotch whisky bar on the first floor. They made their home on the two floors above, so they could skip a late-night drive home after closing. When the Baltimore Sun visited in 2005, the owner had held the building for 23 years.

Lesson: Owning the building you work in can keep a small business in place for decades. It also removes the commute and a second housing payment. Baltimore Sun: Above it all (July 31, 2005)

Shop on the ground floor, family upstairs (2021)

A couple bought a small downtown building in 1988. They ran an electronics repair shop on the ground floor and raised their children in the apartment above. They sold it in 1997 and bought it back in 2004. The wife said having the shop downstairs meant they never paid for day care, and her husband was home when the kids got back from school.

Lesson: For an owner-operator family, a building with the shop below and the home above can save on child care, commuting and rent. That holds as long as both uses fit the business. Duluth News Tribune: Chisholm couple calls commercial space home (Oct. 31, 2021)

Sold the house, moved above the cafe (2007)

A chef worked 12-hour days at her own cafe and commuted twice a day. After she and her spouse did the math, they sold their six-bedroom house and moved into a four-room apartment over the restaurant. The move gave the family more time together and cut a separate mortgage, though they had to adjust to a much smaller space.

Lesson: Living above your own business trades space and privacy for time and lower housing costs, so it suits owners who will actually work there every day. Philadelphia Inquirer: Living above store? Works for them (Oct. 12, 2007)

No privacy above the saloon (2005)

A part-time worker lived in the apartment above a saloon where he also worked. Regulars flagged him down whenever he stepped outside. Coworkers watched who came and went from his door, and he was pulled in for extra shifts. He finally moved out to a quieter townhouse, saying the setup is not for everyone.

Lesson: Before buying a building to live above a business, be honest with yourself. How much noise, contact and lack of privacy can you live with? Baltimore Sun: Above it all (July 31, 2005)

Apartments filled, storefronts stayed empty (2017)

A 700-unit apartment complex at 10th and Market streets announced a restaurant for its ground floor. The restaurant pulled out about 18 months later. More than four years after opening, all 13,500 square feet of its retail space was still empty. The Chronicle found the same problem across 17 storefronts in 20 new buildings nearby.

Lesson: Do not assume the ground-floor shop will rent quickly. Budget for years of empty commercial space, even when the homes above are full. San Francisco Chronicle: SF developers struggling to fill new ground-floor retail (Nov. 21, 2017)

Store tenant gone, loan in default (2026)

A family whose discount clothing chain had gone bankrupt owned the Metropolitan building at 449 South Broadway, with 88 apartments above a ground-floor store. After the store space went completely vacant, the owners defaulted on a roughly $32 million loan. This happened even though the apartments were 91 percent occupied.

Lesson: In mixed-use property, losing the one big commercial tenant can sink the whole building’s finances. Check how much of the income depends on the storefront. The Real Deal: A DTLA mixed-use loan sent to special servicing after $32M default (March 26, 2026)

Costs

Down payment and loan costs. A home-style loan only fits owner-occupied, mainly residential properties (Fannie Mae). Otherwise, plan on a commercial loan, which usually needs a bigger down payment and has shorter terms.
Vacancy in the storefront: you carry the building’s mortgage, taxes and insurance with no retail rent while you look for a tenant.
Tenant improvements and build-out. New business tenants often need plumbing, electrical, venting or accessibility work before they can open.
Commercial-grade insurance and code compliance (fire separation between the shop and homes, accessibility for the public area).
City charges where they exist. San Francisco supervisors looked at a vacancy tax or fee on owners who leave storefronts empty (2017).

How people pay

Fannie Mae buys loans on homes with a business space (such as a day care, barber shop or doctor’s office) only if the borrower lives there as a principal residence, owns and runs the business, and the property is mainly residential.
Buildings with a storefront plus several apartments usually need a commercial or small-balance multifamily loan from a bank or credit union.
An owner-operator business may qualify for an SBA 504 loan (up to $5.5 million) only if the business itself uses at least 51% of an existing building (60% if newly built). If apartments take up most of the space, it likely won’t qualify. SBA 504 loans cannot be used for speculation or investment in rental real estate.
Buying with cash at a tax sale or foreclosure auction removes the risk of loan approval. But it leaves you to fund repairs and vacancy yourself.

Check before you buy

Confirm zoning allows both the business and the homes. Make sure existing units are legal (permits on file with the city or county).
Read every lease: commercial lease length, rent, and who pays taxes and repairs. Check whether the residential units have tenant protections.
Check how long the storefront has been empty and what similar storefronts on the block rent for.
Have the building inspected for fire separation, plumbing, venting and electrical capacity, especially if a restaurant or salon is below the homes.
Talk to a lender early about whether the property qualifies for a residential loan or needs commercial financing.
Get insurance quotes that cover both the commercial and residential parts.
