House Hunting Questions

Feel free to copy and modify according to your own needs.

If there’s an interested and cooperative vendor or real estate agent who can speak with the vendor (or property manager, etc) to get the answers to as many of these questions as you need answered for your health, it’s easier to make better decisions about being able to function in a potential new home.

You can also use the list in other ways. Feel free to use as needed.

Possible intro:

QUESTIONS  regarding potential health issues for interested buyer /renter who suffers from severe allergies and chemical sensitivities.

We need and appreciate your complete honesty when answering these questions, realizing they may seem unusual. There are no right or wrong answers.

Your answers will help us to understand what substances and materials have been and may still be present in this environment, and if these are ones that are safe, or are present in safe amounts for the prospective buyer to be exposed to.  Sometimes trace amounts are dangerous, so we need to know the history. What may be normal and cause no problems for most of us may cause symptoms ranging from mild and irritating, to severe neurological effects, or something similar to what you might expect from someone with a peanut allergy.

We realize that no place will be perfect. The goal is to find a home that is least likely to have an impact on the existing medical condition.  We expect that some remediation or modification may need to be done before moving in to any home, and need to know to what extent this may or may not be possible here.

Thank you for your co-operation.

  1. Hi, I just found out about your website today. It has some great information on it! I am a little chemically sensitive but nothing to the extent of some of the people on here. My background is in real estate development and it has always scared me how many chemicals go into the average home, both in building and in maintenance. Just wondering, how is everyone with concrete homes? I always wondered if this could be a solution.

    • The concrete here had to be done without the usual chemical additives, which cause problems for people.

      The storage areas where the concrete bricks were not painted are still problematic, and in a couple of places I “wallpapered” them with sheets of mylar using double sided painters tape.

      Hempcrete is a newer material that some people are having success with. I haven’t been able to sample any myself, so don’t know how I’d do with it.

  2. Has anyone actually presented this list to a real estate agent and had a vendor return it?

    • I tried!

      Back in about 2008, I think it was, and when vendors balked, it became clear that it was because they had something to hide. They had major liability fears. I was able to discover a few details from other agents that confirmed there were undisclosed problems (like why there might have been a plug-in in the basement or elsewhere = mold).

      I did learn to avoid any place that didn’t want to answer questions!

      If you know anyone who could put together a more agent/vendor-friendly version that would be well received, let me know please!

  3. Did you find a good place to live since then and do you have any pointers? I am thinking I will end up in an apartment and have terror thoughts of bug spraying. It has been 20 years since my last apt then we could not say no. Do you know if that has changed.

    Real Estate: Why scents may not make cents

    April 07,2014

    If you are seriously in the market to sell your home, increase your odds of getting top dollar and more offers by discontinuing the use of fragranced products.

    April 07,2014/Free-Press-Release.com/ — Salem NY

    For many home sellers and real estate agents who believe the TV commercials that claim chemical sprays “sanitize” the air, plug-ins “freshen” the air and Fragrance emitting devices actually clean the air, well…this may not be music to your ears.

    The savvy, health conscious home buyer has added chemical fragrances to their list of what they don’t want to smell when they are looking to buy a home. These chemical fragrances are now listed right next to mold, cigarette smoke odor and animal urine by many home buyers.

    Home buyers today are more educated than ever. Even inexperienced first time home buyers understand that chemical fragrances do not clean the air, they contaminate it with toxic chemicals and more often than not these chemical fragrances make people very sick.

    Home buyers have kids with asthma and allergies. They, themselves, might suffer from migraines, respiratory illness, cancer or fragrance sensitivity. Home buyers know that clean should not have a smell, not of disinfectant or chemical emitted fragrances .

    So, while the location, square footage and price of your home might be perfect for your would be buyer, the smell of your home just might be the deciding factor on why an offer was not written up.

    What does your house smell like?

    Once plug in style fragrance emitting devices are used in a home, the oil / fragrance permeates the wallboard as well as flooring. Similar goes for the fragranced dryer sheets in the laundry room. These chemical odors then circulate in the air vent heating and cooling system and will never come out, no matter what you do.

    With the growing population of people suffering with fragrance sensitivity, Asthma, respiratory conditions, various cancers and allergies, house hunting can often prove to be quite a challenge.

    If you are seriously in the market to sell your home, increase your odds of getting top dollar and more offers by discontinuing the use of fragranced products. Open your windows and let the fresh air in. Clean with non-fragranced products. Your house will then be marketable to all potential buyers… even those with health issues.

    After all, you do want your home to take a buyers breath away… but not literally.

  5. (1) International prevalence of chemical sensitivity and fragrance sensitivity.

    Across four countries (United States, Australia, United Kingdom, Sweden), 19.9% of the general population report chemical sensitivity, 7.4% report medically diagnosed MCS, and 32.2% report fragrance sensitivity (i.e., health problems from fragranced consumer products). For individuals with asthma or with autism, the prevalences are several times higher.

  6. “Prevalence of diagnosed MCS has increased over 300%, and self-reported chemical sensitivity over 200%, in the past decade. Reducing exposure to fragranced products could help reduce adverse health and societal effects.

  7. Fragranced consumer products: exposures and effects from emissions.

    https://www.ncbi.nlm.nih.gov/pubmed/27867426/

    Abstract

    Fragranced consumer products, such as cleaning supplies, air fresheners, and personal care products, are a primary source of indoor air pollutants and personal exposure.

    Previous research indicates that fragranced products can trigger adverse health effects, with implications for workplaces and public places. This is the first study to examine the multiple dimensions of exposures related to fragranced products and effects in the US population.

    The study investigated the prevalence and types of fragranced product exposures, associated health effects, awareness of product emissions, and preferences for fragrance-free policies and environments. Data were collected using an online survey with a nationally representative population (n = 1136) of adults in the USA.

    Overall, 34.7 % of the population reported health problems, such as migraine headaches and respiratory difficulties, when exposed to fragranced products.

    18.6 % respiratory problems;
    16.2 % mucosal symptoms;
    15.7 % migraine headaches;
    10.6 % skin problems;
    8.0 % asthma attacks;
    7.2 % neurological problems;
    5.8 % cognitive problems;
    5.5 % gastrointestinal problems;
    4.4 % cardiovascular problems;
    4.0 % immune system problems;
    3.8 % musculoskeletal problems; and
    1.7 % other.”

    Further, 15.1 % have lost workdays or a job due to fragranced product exposure in the workplace.

    Also, 20.2 % would enter a business but then leave as quickly as possible if they smell air fresheners or some fragranced product.

    Over 50 % of the population would prefer that workplaces, health care facilities and professionals, hotels, and airplanes were fragrance-free.

    While prior research found that common fragranced products, even those called green and organic, emitted hazardous air pollutants, more than two thirds of the population were not aware of this, and over 60 % would not continue to use a fragranced product if they knew it emitted such pollutants.

    Results from this study provide strong evidence that fragranced products can trigger adverse health effects in the general population.

    The study also indicates that reducing exposure to fragranced products, such as through fragrance-free policies, can provide cost-effective and relatively simple ways to reduce risks and improve air quality and health.

  8. “Beyond their immediate effects, VOCs react with other molecules in the air, such as oxygen and nitrogen oxides, to generate ozone as well as fine particulate matter. (Those nitrogen oxides come, in large part, from vehicle exhaust.) High levels of fine particulate matter make it hard to breathe and contribute to chronic lung problems (SN: 9/30/17, p. 18). And while ozone high in the atmosphere helps shield Earth from the sun’s ultraviolet radiation, at ground level, it mixes with fine particulates to form breath-choking smog.”

    ~ Household products make surprisingly large contributions to air pollution

    https://www.sciencenews.org/article/household-products-make-surprisingly-large-contributions-air-pollution

    • Household products make surprisingly large contributions to air pollution

      “In urban areas, emissions from consumer goods such as paint, cleaning supplies and personal care products now contribute as much to ozone and fine particulate matter in the atmosphere as do emissions from burning gasoline or diesel fuel.”

      Everyday products like these emit a bouquet of volatile organic compounds that contribute to air pollution.

    “inconvenience, morale, and preferences are not valid considerations in assessing whether an accommodation would cause undue hardship”.

    • Disability

      The Code protects people from discrimination and harassment because of past, present and perceived disabilities. “Disability” covers a broad range and degree of conditions, some visible and some not visible. A disability may have been present from birth, caused by an accident, or developed over time.

      There are physical, mental and learning disabilities, mental disorders, hearing or vision disabilities, epilepsy, mental health disabilities and addictions, environmental sensitivities, and other conditions.
