If I turn my garage into a bedroom with no kitchen, is it an ADU?

Not in Reno or unincorporated Washoe County. Reno defines an ADU as a dwelling unit with a kitchen, a full bathroom and living and sleeping areas (Land Development Code 18.09.302, Ordinance 6727), and guest quarters, which have no separate kitchen, may not be rented. Washoe County makes a detached structure a dwelling unit when it gets both a kitchen and a toilet (Development Code 110.304.15(c)(4)). A permitted conversion still has to meet the 2024 IRC alarm rules, and the garage separation rules if any garage is left. On a Sparks parcel, ask Sparks Planning. Read 22 October 2026.

Can I put a wet bar or a kitchenette in a converted garage without it becoming an ADU?

Nobody should answer that from a web page, including us. Washoe County’s test depends on a kitchen as defined in Article 902 of its Development Code, and Reno’s definition does not define a kitchenette, so the planning counter decides how the word applies to your cabinets. Get its answer in writing before cabinets are ordered, because the same classification decides the parking and, on a septic parcel, whether Northern Nevada Public Health requires a second septic system.

Do I have to replace the parking if I convert my garage into a family room?

Expect the planning department to ask where the cars will park instead. Reno makes it unlawful to reduce required parking without acceptable alternative parking (Land Development Code 18.04.702(b)(3)); Washoe County requires two spaces per single-family house, one of them in an enclosed garage (Development Code Table 110.410.10.1); Sparks counts one space per bedroom and applies its full parking section when a change raises the count (Municipal Code 20.04.009(A)(3)), with tandem spaces possible by approval. None of these three parking rules names garage conversions, so the answer for your parcel comes from the planning department.

The kitchen is what makes a converted garage an ADU in Reno and Washoe County

In Reno, and for a detached garage in unincorporated Washoe County, a converted garage that already has a bathroom becomes an accessory dwelling unit (ADU) when it gets its own kitchen. Reno’s code defines an ADU as a unit with a kitchen, a full bathroom and living and sleeping areas, and Washoe County says a kitchen and a toilet make a detached garage or shed a dwelling unit; without the kitchen, the space stays a room of the house or becomes what both codes call guest quarters. This page quotes each line with its section (read 22 October 2026), says what crossing it changes, and names the one question to settle in writing first.

01Why it matters

The same garage can become a bedroom or a second home, and the paperwork splits at the kitchen.

Nevada law defines an accessory dwelling unit as “an independent living space” on the same lot as the primary residence, attached, detached or built within it (NRS 278.257(6)(a)). Since 1 July 2026, when the accessory dwelling provisions of Assembly Bill 396, the 2025 state law, took full effect, the ADU ordinance Reno, Sparks and Washoe County must adopt may not prohibit separate kitchen facilities for one (NRS 278.257(1) and (2)(a)). That ordinance does not apply in a region with a planning agency created by an interstate compact, an agreement between states, whose regional plan regulates housing (NRS 278.257(5)). The kitchen is allowed, and in the local codes it is also what makes the space a separate unit.

Reno’s City Council adopted Ordinance 6727, allowing ADUs, on 8 October 2025 (the city’s Zoning Code Clean-Up page, read 22 October 2026), and Reno’s ADU guide, revised 13 October 2025, says you may have one everywhere that allows single-family residences. One exception, as of 22 October 2026: Land Development Code 18.02.603 prohibits ADUs in the Country Club Acres Neighborhood Plan overlay, a zoning layer with its own rules for one neighbourhood; it is one example, not a complete list.

So decide which of three things you are building before anything is drawn: a room of the house, guest quarters or an ADU. They answer to different code sections, and the choice moves the parking count and, on a septic parcel (one where sewage is treated on the lot), the health review. Which authority reads your parcel comes first, and it is the subject of how Reno, Sparks and Washoe County each review an ADU.

02Where the line falls

Reno and Washoe County both draw the line at the kitchen, in slightly different words.

Inside Reno city limits, Land Development Code 18.09.302, as amended by Ordinance 6727, defines an accessory dwelling unit as a dwelling unit that “contains a kitchen, a full bathroom, and living and sleeping areas”. Guest quarters, such as a casita, “do not contain separate and independent cooking (kitchen) facilities and may not be rented”, and Table 3-5 in 18.03.402 allows one detached ADU or one detached guest quarters per lot, not both.

In unincorporated Washoe County, Development Code 110.304.15(c)(4) says “installation of both a kitchen (as defined in Article 902) and a toilet in a detached accessory structure shall render the structure as a dwelling unit and subject to the accessory dwelling unit provisions”. Guest quarters, under (c)(5), have a bedroom and bathroom “but no kitchen or cooking facilities” and no internal access to the house; an attached ADU, under (c)(1), is part of or an addition to a house “designed or configured to be used as a separate and independent dwelling unit”. Only one ADU or guest quarters is allowed per parcel (110.306.20(h); Division Three, annotated 25 September 2026).

Inside Sparks city limits, Municipal Code 20.03.003(B)(1) lets an ADU be a new building, “adapted from an existing building into an existing accessory structure on the same lot”, or “adapted from part of the main structure”. Read plainly, that covers a garage attached or detached, though 20.03.003 never says garage. Where Sparks draws its line is one of the questions section 04 declines to answer.

Northern Nevada Public Health (NNPH) takes the label from Planning: “NNPH will honor whatever classification the Planning department makes” (its Accessory Dwelling and Guest Quarters FAQ, H-482, Rev. 02/2026). Planning’s classification decides the septic review.

03What crossing it changes

Crossing the line changes the parking count, the septic answer and the approval the unit needs.

In Reno and unincorporated Washoe County, an ADU adds a parking space, with Washoe exceptions for a minor ADU. Reno Land Development Code 18.03.405(a)(7) requires “one designated parking space” on site, on top of the house’s own parking (18.04.705, Table 4-6). Washoe County Development Code 110.306.20(g) and 110.306.25(g) require at least one added off-street space, except for a minor ADU, under 500 square feet, on a parcel larger than half an acre; on half an acre or smaller, the Director of Planning and Building may waive that space through a Director’s modification of standards (110.306.25(l)). The state limit is NRS 278.257(2)(b): no more than one additional space where the house’s parking and street parking satisfy the anticipated need.

Converting a garage that holds required parking is a Planning question even with no kitchen. Reno 18.04.702(b)(3) makes it unlawful to reduce required parking “without the establishment of acceptable alternative parking”. Washoe County Table 110.410.10.1 requires two spaces per single-family house, “1 of which must be in an enclosed garage”. Sparks counts one space per bedroom (Table 20.04.011-3), applies its whole parking section when a change of use raises the count (20.04.009(A)(3)), and lets the Administrator, a city official named in its code, approve tandem spaces, one car parked behind another (20.04.009(B)(4)). None of these three parking rules names garage conversions, so Planning says how each applies to yours.

On a septic parcel, where sewage is treated on the lot instead of piped to a sewer, the label decides the system. NNPH requires each dwelling to have its own septic system and designated repair area, ground that must remain available and undeveloped, on at least one acre per system; for guest quarters, NNPH evaluates the existing system to ensure it is sized for the total bedroom count of all buildings, and the connection must meet all setbacks, the minimum distances the rules set, with an adequate code compliant repair area reserved (H-482). How each service then reaches the unit is in how water, sewer and septic reach an ADU.

On a Washoe parcel of half an acre or smaller, a detached ADU needs administrative review under Article 809 (110.306.25(k)), which the county’s ADU Hub says “is completed at a staff level”. Reno’s ADU guide says its Building and Safety Division classifies an ADU as a one-family or two-family dwelling under the current adopted International Residential Code (IRC), the model code for houses, depending on whether it is detached or attached. And the 2024 Northern Nevada amendment to IRC R318.2 requires an egress door, the door you leave by, for each dwelling unit, so an ADU gets its own: a swinging door at least 32 inches wide in the clear, measured across the open doorway.

04The refusal

We will not tell you whether a wet bar, a kitchenette or a Sparks garage crosses the line.

We do not say whether a sink, a bar fridge, a microwave or a two-burner cooktop turns a garage room into a dwelling unit in Reno or Washoe County. Washoe’s test turns on “a kitchen (as defined in Article 902)”, Reno’s definition names a kitchen without defining a kitchenette, and in both places the planning counter applies the word to the cabinets actually drawn.

Nor do we say where Sparks draws its line: this page quotes only its accessory dwelling section, 20.03.003, not the Sparks definitions or the zoning districts where an ADU is allowed, and the online Sparks code, codified through Ordinance 2676 of 27 July 2026, shows 20.03.003 with only its 2015 adoption; anything adopted later would not appear there. Whether that text applies in full after the state changes of 1 July 2026 is for Sparks Planning to say, not us.

Why refuse: that one cabinet moves the parking, the septic system and the approval path at once, so a wrong guess is expensive three ways. Get the answer in writing before cabinets are ordered. Reno’s ADU guide says to email a planner at planning@reno.gov and a building plan reviewer at permits@reno.gov; in Sparks or unincorporated Washoe County, ask the planning counter.

05The garage itself

A garage converted to a bedroom still has to be sealed off from whatever is left of the garage.

Under 2024 International Residential Code R302.5.1, which the 2024 Northern Nevada amendments leave as printed, “openings from a private garage directly into a room used for sleeping purposes shall not be permitted.” Any other door from the garage into the house must be solid wood at least 1⅜ inch thick, solid or honeycomb-core steel at least 1⅜ inch thick, or 20-minute fire-rated, and self-latching with a self-closing or automatic-closing device.

R302.6 and its table ask for at least 1/2-inch gypsum board, or drywall, on the garage side, and at least 5/8-inch Type X, a fire-resistant grade, where living space sits above the garage. R302.5.2 wants ducts in the garage of at least No. 26 gage sheet steel (gage is the thickness of the sheet metal) or another approved material, with no openings into the garage.

Room of the house or ADU, a permitted conversion brings the alarms up to new-home placement: smoke alarms under R310.2.2, and carbon monoxide alarms under the Northern Nevada amendment to R311.2.2. R313.1 sets minimum ceilings of 7 feet for habitable space, the rooms you live in, and hallways, and 6 feet 8 inches for bathrooms, with exceptions, among them one for sloped ceilings. The rest of the work on the building itself, from the concrete slab floor to the insulation the energy code asks for, is in how we convert a garage into living space.
