What a West Asheville Backyard Can Hold Now, and What It Still Can't

Michigan Street runs south from Haywood Road for seven blocks. In early June, a West Asheville land-use lawyer and housing advocate named Marty Benson counted 220 on-street parking spaces there and told Asheville Watchdog that most of them sit empty. He was making the case against the city's parking mandates. He also described the houses he sees going up nearby as "slim-tall" homes of 2,000-plus square feet at $500,000-plus, filling one available lot after another.

Eleven weeks later, the rules he was arguing about changed. On August 25, 2026, Asheville City Council unanimously approved three changes. Duplexes are now allowed across most single-family zoning. Accessory dwelling units can be larger. Minimum parking requirements are gone for developments of all types. For anyone shopping West Asheville this fall, the backyard of nearly every house you tour in the city limits now carries an option it didn't have in July. That option has real value. It also has a ceiling, and the ceiling is the part a listing's "ADU potential" line usually leaves out.

The Cottage Out Back Can't Host Weekend Guests

Start with the rule that catches people. In Asheville, renting out an entire house or apartment for less than a month is a short-term vacation rental, and the city allows those only in the Resort zoning district. West Asheville's residential streets aren't in it. A new backyard cottage there can't be listed as a whole-unit nightly rental.

The other route is a homestay, which rents part of a home while the owner lives there. It comes with tight terms. The operator has to be a full-time resident whose primary home is that property, and they have to stay there overnight for the whole time guests are present. Only one or two bedrooms can be rented, for stays under 30 days. The detail that matters most for a backyard unit is this one: under the Unified Development Ordinance, homestays can't be located in a detached accessory structure. The only exception is a homestay permitted before December 14, 2021 whose use and permit have been kept up.

So the August vote made it easier to build a cottage behind a West Asheville bungalow, and the city's lodging rules still keep that cottage out of the nightly-rental market. What a buyer can count on is a unit for a long-term tenant, an aging parent, a grown kid, or a home office. Those are real uses with real value. They just pencil out differently than a vacation-rental projection does.

What the August Vote Changed

The changes are specific, and the details shape what a given lot can hold.

The current code adds a few details. Covered decks, patios, porches and garages don't count toward the 1,000 square feet. An ADU doesn't count as an extra unit when the city calculates minimum lot size or density. On parking, BPR reported that a state law taking effect in July already bars North Carolina cities and towns from requiring parking for new developments.

The "smaller than the main house" rule matters in West Asheville, where a lot of the housing is modest. On a small bungalow, the main house sets the limit before the 1,000-square-foot cap ever comes into play. The same rule favors the larger, newer houses Benson described. Most of them can support a full-size ADU.

According to city planning staff, duplex eligibility grew from about half of the city to 92%. By parcel count, the council presentation put the jump at 49% of parcels to 99%.

Two Front Doors Can Mean Two Deeds

The duplex change goes beyond a second rental unit. Asheville already treated townhouses as a use with special standards. Those standards waive the district's minimum lot size and width and waive setbacks at a shared wall. The new standards for RS districts cap townhouse developments in RS-2, RS-4 and RS-8 at two attached units, and they keep the side-yard requirement on the side without a shared wall. The council presentation titled the slide "Duplex Ownership Opportunities." That points to a two-unit building split into two separately owned homes on a lot that once held one.

For a buyer, that changes where a West Asheville resale's competition comes from. A tired house on a decent lot now draws interest from people who want to live in it and from people looking at a two-unit build.

The starting point is small, though. City staff counted 18 duplex permit applications citywide from April 2025 through April 2026. The new rules make more possible. They don't create a wave of builders overnight. BPR reported that neighborhood groups had raised general concerns during the process but that no one spoke against the changes on August 25.

Pricing the Option in a Six-Month Market

The market numbers set how much a buyer should pay for that option. Canopy MLS's September 2026 Local Market Update for the City of Asheville, current as of October 5, shows a median sales price of $510,000 for the month. Sellers received 93.1% of their original list price. Inventory was 975 homes, or 6.4 months of supply. The year-to-date picture is softer. Through September 2026, the city's median was $495,000, down 3.6% from the same stretch of 2025. Days on market until sale averaged 73, compared with 55 a year earlier. Canopy notes that these price figures don't account for seller concessions, so the actual net prices can be lower.

Canopy doesn't publish a West Asheville or 28806 breakdown, so these are citywide figures. They still describe the conditions every West Asheville offer gets written in. Six-plus months of supply and homes that typically sell below their original asking price give a buyer room to ask what "development potential" is actually worth.

The cost of building is part of that answer. One Asheville builder's January 2026 guide puts new custom homes at roughly $225 to $300 per square foot at the entry level and $300 to $400-plus in the middle of the market. Those numbers cover whole new houses, not ADUs, so they're only a rough guide. A buyer who pays extra for "ADU potential" still pays for the construction afterward. The premium is a payment for permission, and the August vote gave that permission to nearly every comparable lot in the city.

Questions Worth Asking About a West Asheville Listing

1. What is the zoning? The city sends residents to Map Asheville to look up zoning by address. "West Asheville" isn't a zoning category, and the city says it doesn't draw neighborhood boundaries.
2. How big is the main house? An ADU has to be smaller than the primary structure, so a compact bungalow limits its own backyard unit.
3. Is there an existing homestay permit? A detached unit permitted as a homestay before December 14, 2021 can keep operating if the use and permit have been kept up. A new one can't get that status.
4. What income is the listing assuming? Long-term rent and nightly rates lead to very different numbers. Only one of them fits a detached unit on a residential lot.
5. Does the listing price already include the option? With 6.4 months of supply citywide as of September 2026, comparable lots likely have the same permission.

A Few Quick Answers

Can I build an ADU and a duplex on the same lot? The current code allows one ADU on a lot with no more than two residential units. A duplex plus one ADU is permitted, subject to the other standards in the ordinance.

Does a garage count toward the ADU size limit? Covered decks, patios, porches and garages are excluded from gross floor area under the ADU standards.

Can I rent a room in my main house to short-term guests? A homestay permit allows one or two bedrooms rented for stays under 30 days. The permit holder has to live there full time and be present overnight while guests are staying. Permits are reviewed every year.

Does any of this apply outside city limits? These are City of Asheville rules. Homes outside the city follow different zoning, so the address lookup comes first.
