State & Local

Updated: November 2016


As of November 2016, eleven states offer ongoing, statewide rebates or tax incentives for

* Pellet stoves: Alabama, Arizona, Idaho, Maine, Maryland, Montana, New York, Oregon
* Wood stoves: Arizona, Idaho, Maryland, Montana, Oregon
* Wood or pellet boilers: Alabama, Maine, Massachusetts, Montana, New Hampshire, New York, Vermont,

Appliance eligibility requirements vary from state to state. For pellet stoves, for example, Maryland and New York require stoves to emit no more than 2 grams per hour; in Maine and Oregon, it’s no more than 2.5 grams an hour. In other states you must turn in an old wood stove (Montana), convert a fireplace to a stove (Arizona), convert your primary heating system to wood or pellets (Alabama) or displace oil, electricity, or propane heat (Maryland).

Many other states have regional wood stove change out programs. For more info:

Regulations on uncertified stoves

As of November 2016, these states and regions have the following regulations. This list likely omits relevant regulations and will be updated. Mostly, this list focuses on how states and counties have attempted to reduce or stop the use of old stoves that are not certified by the EPA. Some jurisdictions have tried to stop their sale and installation; others have banned their use, usually after years of providing incentives to upgrade to EPA certified units. And others require their removal upon the sale or remodel of a house. All of the areas regulating these old, uncertified stoves are grappling with very high levels of wood smoke pollution, and are also regulating other sources of air pollution.

Forbids Use of Uncertified Stoves Forbidding the use of old, uncertified stoves is rare in the US and likely only used after years of offering funding to change out old stoves.

  1. Tacoma-Pierce County, Washington: As of October 2015, it is illegal to purchase or operate an uncertified wood stove in the Tacoma-Pierce County Smoke Reduction Zone.
  2. Marin County, California: Forbids use of non-certified appliances since July 2008 and forbids installation of non-certified stoves in new construction or remodels.
Forbids Sale and/or Installation of Uncertified Stoves:

Two states and a number of urban areas and counties do not allow old, uncertified stoves to be sold or installed off the second hand market. Where change out programs occur, banning the future installation of old stoves is a key way to preserve air quality gains.
  1. Washington: Since 1992, has forbidden sale and installation of wood stoves or inserts that are not certified to the stricter Washington state emission standards.
  2. Oregon: Forbids sale and installation of wood stoves or inserts that are not certified. Oregon began certifying stoves in 1984 and the EPA in 1988.
  3. Denver-Metro area, Colorado: Prohibits sale and installation of new or used uncertified wood burning appliances
  4. Summit County, Colorado: Forbids the installation of a non-certified wood stove in a new home or as a replacement unit for an existing non-certified stove.
  5. San Joaquin Valley, California: Forbids sale and installation of non-certified stoves.
  6. Town of Mammoth Lakes, California: Uncertified stoves prohibited from being installed in the town. No more than one EPA-certified wood stove can be installed in new single-family detached dwellings.
  7. Pinal County, Arizona: Uncertified stoves prohibited from being installed in “Area A”.
Forbids Installation of Fireplaces

  1. Denver Metro area: The installation of fireplaces is not allowed unless they are equipped with an EPA Phase II wood or pellet burning insert, or electric or gas log.
  2. California Bay Area: Forbids installing fireplaces or stoves in new construction
Uncertified Stoves Must Be Removed

  1. Oregon: Uncertified stoves must be removed when a home is sold.
  2. Marin County, California: Non-certified stoves must be removed upon a home's remodel.
  3. Truckee, California: All non-certified stoves must be removed by May 1, 2008. A fund gave rebates to those turning in their old stoves to recycling centers. No interest loans were also available for low-income families for the purchase of a newer model wood stove. Masonry stoves and pellet stoves are not required to be removed, even if they are not certified.
  4. Libby, Montana: A well-publicized effort to remove polluting stoves in this community required an all-out ban of non-certified stoves in order to ensure the success of the program in 2007.
