Many high-turnover multifamily units have tight budgets, both at initial design and/or at resyndication. Value engineering is a must, which means stock layouts and commercial-grade finishes. Kitchens represent a large cost of each project. We assessed a minimalist kitchen approach to find additional cost savings for high-turnover property types. A minimalist kitchen, in this case for affordable housing or barracks, keeps every function residents need and drops the parts that burn power, waste water, add maintenance tickets or slow a unit turn. The kitchen itself stays, because residents without one say it hurts them. In our scorecard, nine swaps cleared our own internal bar, led by replacing the garbage disposal with a permanent sink screen (which allows for removal or repurposing of the disposals dedicated electrical circuit as well as water savings and fewer plumbing maintenance tickets).
We bought a 33-unit building in 1960s vintage C-neighborhood in Los Angeles, and its drains started failing within the first year. Since then we've looked hard at every part in a high-turnover unit kitchen, and when we couldn't find an existing solution to the age-old drain clog in the kitchen sink, we invented a solution ourselves, see our origin story of the permanent sink screen or more about drain protection for properties and facilities.
The goal here is assess value-based components in the design of a minimalist kitchen. Picture the stripped-down interior of a Tesla Model 3 next to the dashboard of a typical mass-market car. That's the idea here. Affordable housing, barracks and other high-turnover stock run on tight budgets, and every extra appliance is one more cost during development, one extra item to clean, test or fix at the next turn.
A minimalist kitchen usually means clear counters and fewer gadgets. In a high-turnover unit, it means fewer parts that use power, water or maintenance hours.
Why should a high-turnover unit have a kitchen at all?
Because residents who go without one say it hurts them. GAO's 2023 report on military barracks puts it plainly: "Service members in 10 of 12 discussion groups told us the lack of or limited access to kitchens or kitchenettes in the barracks negatively affected them."1 GAO's footnote 45 adds that the other two groups lived in barracks with kitchens.1
Under DOD standards, permanent party barracks without living rooms must include a kitchenette. Even so, GAO observed a barracks room with a microwave and nothing else. It heard that residents without kitchens generally rely on microwaveable meals or fast food, and installation officials told it that retrofitting older barracks with kitchens is challenging and costly.1
Affordable housing programs set a floor too. California's tax credit program requires a refrigerator in every low-income unit and a range in non-SRO units.2
So the kitchen stays, and the time to make it efficient is on the first drawing, or the next drawing before resyndication.
How did we grade each kitchen swap?
We only recommend a swap when either we have experience with the swap and/or significant additional evidence (Grade A) or we're more confident than a coin flip (Grade B) that it delivers the saving against the conventional amenity.
| Grade | Confidence | Evidence behind it |
|---|---|---|
| A | Highest | Code text, or an agency measurement directly on point |
| B | More than a coin flip | An agency, extension or research source on point |
| Below the bar | Not conclusive | Indirect, vendor-only or contradicted evidence |
The grades are our judgment, anchored to the sources cited below. They aren't computed statistics.
Which kitchen swaps cleared the bar?
Nine did. Four are grade A, backed by our experience, code text and/or agency figures.

Why replace the garbage disposal with a permanent sink screen?
The disposal uses water every time it runs, and it puts a powered appliance under every sink that requires a dedicated electrical circuit from the panel. The SemperScreen® permanent sink screen replaces the complete kitchen sink drain assembly in one part: flange, tailpiece connection and permanent screen, and allows removal or repurposing of the dedicated electrical under-sink circuit. For the owner economics, see the cost of garbage disposals in rental properties.
- Water. The common 30-second rule runs water for 30 seconds before and 30 seconds after each grind.3 EPA writes its WaterSense at Work guidance for commercial and institutional facilities, which is where barracks kitchens sit. EPA's WaterSense at Work best management practices identify a food strainer in the sink as a replacement for food disposal equipment.4 The sink still uses water for rinsing; the disposer's share is what goes away.
- Clogs. Drain and plumbing clogs are one of the top three maintenance ticket categories, and they come from human error that no training program fixes. A plumber's service call runs $250+ per call. The permanent sink screen stops food waste down to the size of a dry grain of rice, ensuring most food waste that can harm a drain stays out of the drain.
- Inspections. For HUD-assisted properties, HUD's NSPIRE Sink standard, Version 3.0, lists "Water is not draining from the basin of the sink" as a Moderate health and safety risk, with 30 days to correct.13
- Dishwashers. Under the California Plumbing Code (2025, §§ 414.3 and 807.3) and the International Plumbing Code (2024, § 409.4), dishwashers need not discharge into disposals.14 Keeping a dishwasher doesn't mean keeping a disposal.
Converting units you already have? Start with how to change a garbage disposal to a regular drain, then compare what to install after removing a garbage disposal. Our guide on how to reduce clogged drain maintenance tickets covers the operating side.
SemperScreen® recommends that you always refer to local building codes when modifying a building's plumbing system.
How should the rest of the minimalist kitchen change?
Cook electric with temperature control and vent outdoors.
Induction cooking
ENERGY STAR puts induction at about 85% efficient, electric resistance at 75–80% and gas at about 32%, and notes that the cooktop surface stays cool to the touch.8 Going all-electric also takes gas piping out of every unit.
Temperature control matters here. NFPA found that cooking caused 49% of reported home fires and 45% of home fire injuries in 2013–2017, and that households with electric ranges had 2.5 times the fire rate of gas.15 So skip bare coil burners. Use induction, or coil burners that pass the UL 858 cooking-oil ignition test in effect since April 2019.16 For barracks, the Navy now allows in-room cooking appliances only with automatic shut-off and unexposed heating elements, and it bans open flame.17
One turnover note: induction needs magnetic cookware, so say so at move-in.
The oven, in SRO and barracks units
EPRI measured a single-serve frozen sandwich at 75 Wh in a microwave, 297 Wh in a toaster oven and 486 Wh in a conventional oven.9 For one resident cooking small portions, a microwave or a combination microwave-convection unit covers the job. Check program rules first: California's tax credit program requires a range (cooktop and oven) in non-SRO low-income units, while SRO units need at least a cooktop or microwave.2
The range hood
The hood stays, ducted outdoors. California's 2025 Energy Code (Title 24, Part 6) doesn't accept a recirculating hood for kitchen exhaust. In a unit under 750 sq ft, a hood over an electric range needs 65% capture efficiency or 160 CFM; over a gas range it needs 85% or 280 CFM.7
The refrigerator
Top-freezer models use 10–25% less energy than side-by-side models, and automatic ice makers and through-the-door dispensers add 14–20%.10 Leave them off and the fridge needs no water line behind it.
The faucet and the hot water run
California caps kitchen faucets at 1.8 gpm at 60 psi, with a temporary boost to 2.2 gpm that returns to 1.8 by default.11 We'd specify that default everywhere. It saves water while rinsing; filling a pot takes the same volume either way.
The U.S. Department of Energy's Building America Solution Center describes a hot water delivery limit of 0.5 gallons stored between the hot water source and any fixture.12 Put the kitchen sink on the bathroom wet wall, close to the water heater.
That also argues for a single-wall or galley layout with the sink on the shared plumbing wall. For what wasted water costs an owner, see water waste and NOI in multifamily properties.
Which circuits come out of the kitchen?
The disposal's. Under-sink wiring for a disposal is typically a switched receptacle, and a receptacle within 6 feet of the sink needs GFCI protection, so removing the disposal takes out the switch, the receptacle, its GFCI and the circuit or circuit share behind them.5 Multiply that by every unit in the building.
The two 20 A, 120 V small-appliance branch circuits stay; the NEC requires them for kitchen countertop receptacles.6 So do the refrigerator receptacle and the cooktop circuit.
What failed the bar?
Some ideas look minimal on paper and still lost. The dishwasher is the big one.
| Idea | Why it failed |
|---|---|
| Drop the dishwasher to save water or energy | ENERGY STAR says a certified dishwasher saves 8,400 gallons a year and uses less than half the energy of washing by hand.18 |
| Use a recirculating hood, or no hood | California's 2025 Energy Code doesn't accept a recirculating hood for kitchen exhaust.7 |
| Drop the oven in California non-SRO tax credit units | The program requires a range (cooktop and oven).2 |
| Fit bare coil burners with no temperature limiting | Induction cooking wins. Electric-range households had 2.5 times the fire rate of gas.15 |
| Pick counters, cabinets and shelving for turnover | Common choices, but no source we found reaches the bar. |
Frequently asked questions
Do barracks have kitchens?
Not always. DOD standards require a kitchenette in permanent party barracks without living rooms, but GAO observed a barracks room with a microwave and nothing else, and some residents' only other option was a central kitchen shared by hundreds of residents.1 The two GAO discussion groups that didn't report harm from limited kitchen access lived in barracks with kitchens.1
Does removing the garbage disposal save water?
Yes, the disposer's share. The common 30-second rule runs water for 30 seconds before and 30 seconds after each grind.3 EPA notes that a food strainer itself "doesn't use water."4 Residents scrape food into the trash or compost, and the sink only uses water for rinsing. SemperScreen® recommends that you always refer to local building codes when modifying a building's plumbing system.
Should a minimalist kitchen drop the dishwasher?
Keep it if the water and energy bill is the goal. ENERGY STAR says a certified dishwasher saves 8,400 gallons a year and uses less than half the energy of washing by hand.18 Drop it only for space or first cost. And a kept dishwasher doesn't need a disposal: under the CPC (2025) and IPC (2024), dishwashers need not discharge into disposals.14
Is induction worth it over a coil range?
On efficiency, induction runs 5–10% ahead of electric resistance and about 3 times ahead of gas, per ENERGY STAR, and its surface stays cool to the touch.8 In high-turnover units, temperature control matters as much: NFPA found 2.5 times the fire rate in electric-range households compared with gas.15
Can a barracks or SRO kitchen skip the oven?
Often, yes. EPRI measured a single-serve frozen sandwich at 75 Wh in a microwave against 486 Wh in a conventional oven.9 Check your program first. California's tax credit program requires a full range in non-SRO units and accepts a cooktop or microwave in SRO units.2
Start at the drain
For rental and property teams: We know you have at least one drain that keeps clogging (we have experience with those). Contact us and let's discuss testing our permanent sink screens in those bad drains.
"Clogged drain lines in our apartment buildings are significantly reduced after installing SemperScreen® sink strainers. This product pays for itself 5 times over with just the first blockage or repair it prevents. Very few products in the apartment industry have that kind of return."
