States & Change-outs

State Policies and Change-out Programs

A wide range of policies toward wood and pellet stoves has cropped up across the country. Some areas with widespread air inversions need to curb wood smoke, whereas other areas promote modern wood and pellet heating to reduce reliance on fossil fuels. This page lists the major types of restrictions on wood heating as well as a menu (below) to view states' incentives and regulations for wood stoves as well as states' stove change-out programs. As of June 2022, six states offer ongoing, statewide rebates or tax incentives to purchase and install a stove or boiler.

Notable State Policies

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. Colorado: prohibit people from selling new or used wood-burning devices unless they meet current (Step 2) EPA certification and emissions performance requirements.

  4. Denver-Metro area, Colorado: Prohibits sale and installation of new or used uncertified wood burning appliances

  5. Fairbanks non-attainment area, Alaska: Rules prohibit a person from selling, leasing, or conveying a wood stove or pellet stove with emission limit more than 2.0 grams per hour.

  6. Summit County, Colorado: All new stoves installed must be EPA Phase II approved devices

  7. San Joaquin Valley, California: Forbids sale and installation of non-certified stoves.

  8. 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.

 

Uncertified stoves must be removed upon sale of home

  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. Fairbanks non-attainment area: Wood and pellet stoves that do not have EPA-certification must be removed from the property before the property is sold.

 

Forbids installation of wood-burning 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.

  3. New York City – Effectively bans wood heaters as it prohibits the combustion of any substance that emits 50 kg or more of carbon dioxide per million British thermal units of energy within a building.

Restricts installations of outdoor wood boilers (hydronic wood heaters)

Many states and counties restrict the installation of outdoor wood boilers by limiting the kinds that be installed, like New York, or limiting where they can be installed like in Vermont, where you have to have a 100 foot set-back from your property line, for example. The State of Wisconsin assembled a list of municipalities that restrict outdoor boilers that is nine pages long. Connecticut, Indiana, Maine, Massachusetts, Pennsylvania and Utah also have property line set-backs and most also have minimum stack height regulations.

Forbids sale of new, uncertified wood or pellet stoves

​At the federal level, the EPA forbids the manufacturer, advertising and sale of residential wood heaters that do not pass emission regulations and become certified. Consumers rarely have to worry about this, as new uncertified stoves should not be on the market. One big exception is that some companies openly ignore EPA regulations and continue making and selling outdoor wood boilers for the residential market and the EPA has been ineffectual at enforcing its rules with these companies for many years.
