Home daycare or home occupation in a DC rowhouse: when the fire sprinkler question comes up, and when it does not

A rowhouse in Brightwood takes in four toddlers from the block. A basement in Capitol Hill becomes a therapist’s office two days a week. A Columbia Heights house grows from a small daycare to twelve children and a second caregiver. Each of these is a home occupation in the District’s eyes, and each one brings an inspector through the door who will look at the ceiling and ask about sprinklers. The answer depends on how many people are receiving care, how old they are, and which floor they are on. Here is how the question gets decided, and what it costs when the answer is yes.

Two agencies, two sets of rules

A home daycare in DC is licensed by the Office of the State Superintendent of Education, which calls a provider’s own residence a child development home when it serves up to six children and an expanded child development home when it serves up to twelve. The license requires a fire inspection and a certificate of occupancy for the use, which is where the Department of Buildings comes in with the construction codes. The two sets of rules overlap but are not the same. The licensing rules care about alarms, exits, drills, and where infants sleep. The building code cares about occupancy classification, and that is what decides whether a sprinkler system is required.

Five or fewer stays a house

The construction codes draw a line at five people receiving care inside a dwelling unit. Below that line, the house is still a one or two family dwelling, and the sprinkler rules that apply are the dwelling rules. For a rowhouse built or gut renovated under the current code, that means the 13D system it already has; the gut renovation article covers when that applied. For an older rowhouse that was never required to have one, the daycare use at five or fewer does not reach back and require a retrofit. The licensing inspector can still ask for things the building code does not, and in our experience the basement is where that happens, which is the next section.

Six to twelve pulls in the commercial code

Past five, the use stops being a dwelling and becomes a daycare occupancy under the commercial building code. Children older than two and a half fall in the educational group; children two and a half and younger fall in the institutional daycare group, because they cannot get themselves out. The institutional group is the one where sprinklers are required throughout the building in nearly every case, and an expanded home with infants in it will meet that requirement during plan review. The educational group has a square footage threshold a rowhouse never reaches, but it also has exit rules that an upper floor or a basement room often fails without a sprinkler system to trade against. The code trades article explains that trade in the rowhouse context, and the 13D versus 13R versus 13 article explains why a daycare occupancy may push the design past a 13D system.

The basement is where it gets decided

Most DC rowhouse daycares want to use the basement, because it is the room with its own entrance and the washable floor. The licensing rules restrict where the youngest children can be in relation to the exit, and a below grade room with one stair up and a window well is the case that fails. A sprinkler system does not change the licensing rule on its own, but it changes the building code answer on the exits, and inspectors from both agencies treat a sprinklered basement very differently from an unsprinklered one. If the basement is also an English basement unit that was legalized under the ADU rules, it may already have heads, and the daycare conversation starts from there.

What it costs when the answer is yes

A retrofit in an occupied rowhouse lands in the published range of $2 to $7 per sprinklered square foot, and a daycare retrofit sits toward the top of it for two reasons. The work has to happen around a business that cannot close for three weeks, so it goes room by room on evenings and weekends, and the design often has to carry the building code occupancy rather than 13D, which adds heads in spaces 13D would skip. On a 1,400 square foot rowhouse with a finished basement, that is the difference between a system that covers the living floors and one that also covers the closets, the furnace room, and the under stair storage where the strollers live. Water supply follows the same path as any other retrofit, and the service sizing article covers the flow test.

The other home occupations

A therapist, an accountant, a hair stylist seeing one client at a time, a tutor with two students: none of these put people in care, and none of them change the occupancy of a dwelling on their own. The home occupation permit limits how much of the house the business uses and how many clients and employees are present, and inside those limits the sprinkler question does not come up. It comes up when the business starts to look like one of the uses that has its own occupancy group, meaning care of children or adults who cannot leave on their own, overnight lodging, or more people than the permit allows. The short term rental article and the group house article cover the lodging side.

How to run the question before you apply

Count the children you plan to serve at the top of the range, not the start, and write down their ages. Decide which rooms they will be in, and whether any are below grade or above the first floor. Take that to a licensing specialist and to a sprinkler designer in the same week. If the count stays at five or fewer on the main floor, the sprinkler answer is likely to be whatever the house already has. If the count goes past five, or the infants are in the basement, get the sprinkler drawings started before the certificate of occupancy application, because the permit review is the long pole and the license waits on it.
