If you own or live in a triple-decker in Somerville, you already know the building has a personality. Three stacked apartments, a front hall that everyone walks through, a back staircase that collects bikes and recycling bins, porches on every floor and a yard that somehow belongs to everybody and nobody. Keeping all of that clean is not one job. It is several small jobs that overlap.
This guide is for owner-occupants who live on one floor and rent the others, for landlords who manage the whole building, and for tenants who want to understand what is reasonable to expect. It breaks the house into zones, explains what each one needs, and gives you a simple calendar that fits the way Somerville actually works, from the September 1 lease rush to the first snow on Winter Hill.
A triple-decker is three homes plus one shared building
Most of the triple-deckers in Somerville went up between the 1880s and the 1920s, built tall and narrow on small lots so working families could live close to Boston. The layout is almost always the same: a unit on each floor running front to back, a front entry and hall, an enclosed back stair, and porches stacked on the front, the back or both.
That design is the key to cleaning it well. Each apartment is a private home with its own kitchen and bathroom. The halls and stairs are shared space that every resident uses and no single tenant feels responsible for. The porches, siding and yard are outdoor space that takes the full force of New England weather. When cleaning goes wrong in a triple-decker, it is usually because nobody decided who handles the shared and outdoor parts.
Who cleans what: owner-occupants, landlords and tenants
Inside each apartment, the person living there normally keeps it clean day to day. That part is simple. The gray areas are everything between the apartment doors and the street.
Owner-occupants often end up doing the shared spaces themselves because they live there and see the mess first. That works for a while, but it tends to turn into quiet resentment. A small, regular common area cleaning takes the question off the table and keeps things friendly with the tenants upstairs.
Landlords who do not live in the building usually need a clear plan in writing: what gets cleaned in the halls and stairs, how often, and who handles the porches, bins and yard. Check your lease and any local rules that apply to rental property, and put the cleaning expectations in the lease so tenants know what is included. When an apartment turns over, a full deep clean of that unit before the next tenant moves in is the easiest way to start each lease on the right foot.
Inside the units: radiators, old floors and area rugs
Triple-decker apartments have details that newer buildings do not. Cast iron radiators collect dust in every fin, and they need attention before heating season so the dust does not bake on. Original hardwood floors, built-in china cabinets, deep window sills and tall painted trim all take more time than a flat modern wall.
Kitchens and bathrooms in these buildings are often small and were renovated at different times, so one unit might have a new tiled shower and the next an older tub with years of soap scum. Expect each unit to need a different amount of work, even though the floor plans match.
Area rugs deserve their own mention. Because so many units have old hardwood, tenants and owners lay down rugs and runners to warm up the floors and quiet the footsteps for the people below. Those rugs trap the sand and salt that come in all winter. Vacuuming helps, but a rug that has been down for a few seasons usually needs a real cleaning, and having it cleaned in the home saves you from hauling a heavy rug down three flights of stairs.
Front halls and back stairs: the parts everyone uses
The front hall is the first thing a visitor or a prospective tenant sees. It picks up mail clutter, shoe prints, dust on the banister and grit on every tread. The back stairs are worse, because that is where bikes, strollers, laundry baskets and trash bags travel up and down.
A good shared space cleaning usually covers sweeping and mopping the stairs and landings, wiping banisters and railings, dusting light fixtures and window sills, cleaning the glass on the front door, and clearing cobwebs from the corners and ceilings of the stairwells. In winter, the bottom steps and entry mats need extra attention because that is where the salt and sand pile up first.
For most triple-deckers, a common area cleaning every two weeks or once a month keeps things under control, with more frequent visits in the snowy months. Write down what is included so tenants, owners and the cleaner are all working from the same list.
Porches, siding and the back yard
Stacked porches are one of the best parts of living in a Somerville triple-decker, and one of the hardest to keep clean. They collect pollen in spring, leaves in fall and grime all year, and the ceilings and railings are easy to forget. Painted wood on older porches can be delicate, so most pros look at the condition of the wood and paint before deciding how to wash it.
The siding, the outside of the windows, the front door and the trim all carry a film of dirt from traffic, trees and weather. A periodic exterior house cleaning brightens the whole building, and pressure washing the front steps, walkway and any concrete in the back makes a visible difference, as long as the surfaces can handle it.
The back yard is often a small patch of grass, a parking pad and a corner for the trash and recycling bins. If nobody owns that space, it quickly fills with leaves, overgrown grass and litter. Regular lawn mowing in the warm months and a yard cleanup in spring and fall keep it usable for everyone and make the building look cared for from the street.
A simple yearly calendar for a Somerville triple-decker
Late summer: many Somerville leases end on August 31 and start on September 1, so plan deep cleans for any units that are turning over and book them early. This is also a smart time to clean the halls and stairs before new tenants move furniture in.
Fall: clean the radiators before the heat comes on, clear leaves from the porches and yard, and wash the porch floors and railings before winter sets in.
Winter: increase the common area cleaning, focus on entry mats, the first few stair treads and the back stairs, and keep rugs in the units from becoming salt traps.
Spring: this is the big reset. Wash the siding, windows and porches once the pollen season slows down, pressure wash the steps and walkways, clean rugs that have carried the winter, and do a full yard cleanup so the grass is ready for mowing season.
