A housing condition survey is a time-honored technique often undertaken in conjunction with a housing element of a comprehensive plan, a specialized housing plan for a city, a needs assessment for a grant application or for the federal Community Development Block Grant program in the U.S., or a neighborhood plan. If you don't understand the term, an "element" of a comprehensive plan can be thought of as a chapter.
While often an activity of the city or town, a community development corporation, nonprofit housing developer, or neighborhood association might greatly benefit from such a survey.
The housing condition survey looks at the exterior of either all residential properties in an area of interest, or a random sample of properties, depending on available funding and person power. Sometimes volunteers conduct the survey, and this is perfectly appropriate if the volunteers are trained and provided with written directions, and if rating choices are limited so that volunteers will get it right most of the time.
Be aware that funding sources are likely to frown on the volunteer-led survey, so this approach is most useful when the neighborhood itself is the primary audience for the results.
First, you will want to make sure that every property address is noted correctly on a survey form before sending out the field team, unless you do not have access to that information and need to collect it. In the very rare event that your town is lacking this basic information, ask at the post office about their available data or ask utility providers. Also note whether the residence is a single-family dwelling or has an identifiable number of units more than one.
Second, the city should complete some blanks on the applicable zoning district and whether there are known zoning violations at the property, number of occupants if known, and any outstanding code violations.
Third, typically the housing condition survey contains a checklist of possible problems with the house. We are going to assume that the people performing the survey are either volunteers, interns, planners, or some other employee that does not have a detailed background in structural analysis. If the field crew is more well versed in structural appraisal, the questions can become much more sophisticated.
We maintain that in most cases, that additional level of detail is not necessary. Our rationale for this brash statement is that the maintenance level of the exterior paint job is likely to be highly correlated with whether a crack in the foundation is attended to. There are many exceptions, of course, the most notable being an area of seismic activity or recent storm damage, where the structural integrity of the building may be the main story.
In the event of natural disaster recovery, you are highly advised to find skilled inspectors if you are undertaking a housing condition survey on which funding decisions will be based.
Note that housing condition surveys are conducted from the sidewalk or edge of the property in almost all cases. A few cities may have laws in place that allow their inspectors to enter an occupied home, but this is increasingly rare. So this is a sidewalk survey, and sometimes can be performed effectively as a windshield survey. Windshield survey is the term for when some type of planning-related survey can be done without getting out of the car. In denser neighborhoods, though, we suggest that the survey takers travel on foot for a better look.
If money and time are limited, you could opt for a windshield survey with a sidewalk survey on randomly selected blocks. Whether professional or volunteer, we recommend that the survey team travel in pairs. This makes the work go faster, because one can drive or navigate, and the other can act as note taker. Also in some neighborhoods, safety will be a concern.
OK, let's go on to the promised sample questions. Divide the observations up into logical units, which in most places would be as follows:
We have a few words of wisdom for you about the construction of the survey. As in all research, begin with the end in mind. How will you analyze the data and present it? Is your user primarily the city government, which will utilize it to develop leads for code enforcement? Is this a screening survey for your own information, or will you be presenting it to a funder or a city government for action? If the latter, you will want to be more professional and precise in your questions. If you are mostly trying to understand your own neighborhood better, there are real benefits to leaving the survey a little looser so that the survey takers feel free to simply note anything of interest that the form does not address specifically.
We also suggest that you conduct the survey within one season of the year. If you are in a very leafy neighborhood, there can be real benefits to a winter survey. The disadvantage of course is that you want to avoid snow cover.
Now that we have given the overview of possible questions for your survey form, we also want to assure you that you may be able to do a very meaningful housing condition survey for your neighborhood simply by having volunteers note the following things:
That in itself can be important, especially in an urban neighborhood where housing maintenance varies widely, or in an older suburb where many properties are well kept and a few are problems. This simple survey should be done very quickly over a period of no more than a couple of months, and results should be tabulated quickly.
You can use a simple color coding system to show whether 0-10% of homes on a block were below average, 10-25%, 25-50%, or more than 50% for example. If you have a mostly intact neighborhood, the color coding could be as simple as a color for one house on a block being Below Average, and another color for more than one house on a block Below Average.
If you use volunteers for either a checklist housing condition survey or for the generalized one, in which each home is rated as falling into three to five categories, you must train the volunteers by having them walk through actual blocks. You not only are helping individual volunteers visualize and prepare for the task, but also you are trying to get the volunteers to agree on common standards.
If there is no neighborhood organization, use your concern about housing quality to start a neighborhood association. On the other hand, if a neighborhood organization is well-established, you could use block units to accomplish the survey, again assuming they are well-trained. The survey could provide the rationale for creating or re-energizing block units if none exist.
You also may choose to give some criteria for each rating that you use, and even illustrate those with photos. However you accomplish it, standardization from one rater to another obviously is important to determining whether the entire exercise of the housing condition survey is worthwhile and how much faith to place in the results. Don't skimp on training.
One other tip for composing the housing condition survey form is that in most cases, you can avoid the questions asked by the U.S. Census. Their housing data covers different items, but you should be aware of what is already available to you before you design your own windshield survey, or better yet, walking survey.
We also have omitted any discussion of a wide range of other topics that are often discussed in a housing section of a general plan. The housing condition survey only addresses a narrow range of aspects of the maintenance of an existing residence, and does not touch on characteristics of occupants, utility availability, and many other items of interest. But it is an amazingly valuable tool for neighborhood groups and for planners.
