How I appraised a property with a non-permitted garage conversion

How do we value a non-permitted garage conversion? Today I wanted to share a real life example of a property I appraised. I’ll keep things fairly brief because it’s impossible to get to everything in just one post. Though I do have a 10-minute audio clip for more depth on conversions. Any thoughts?

UPDATE: Read part 2 of this post HERE.

Garage Conversion Formula: It would be nice if there was a one-size-fits-all value adjustment we could apply to any conversion, but that’s not how it works because conversions vary tremendously in size and quality – not to mention some neighborhoods accept them and others really don’t.

Golden Data: In this case the conversion was nicely done and was even on a crawl space like the rest of the house. I searched the neighborhood for garage conversions over the past few years and literally found none. But I did have one very lucky bit of data since the subject sold four years ago on MLS as an arms-length sale. This means I was able to look back in time and find how the subject fit into the context of neighborhood prices.

What I wrote in my report: Based on the previous sale in 2012, it is clear the market recognized the subject property’s extra size as square footage and paid for it as such in the marketplace. The lack of permits on the garage was definitely disclosed in MLS. At the time of the sale in 2012 the market was willing to pay about $15,000 (6%) less for the subject property compared to otherwise similar homes that had a garage. In today’s market were no recent sales with a garage conversion, so the appraiser used historic data to give a downward $15,000 adjustment to Comps 1-3. The garage adjustment would really be reasonable anywhere between $15,000 to $20,000, but since the subject has been upgraded extensively in recent years it made sense to adjust at the lower end of this range since upgrades lessen the negative for not having a garage.

If I didn’t have a previous sale: Without a previous subject sale, I’d need to find other garage conversions in the neighborhood or search in a competitive area of town to try to find a reasonable adjustment for the lack of a garage (and lack of permits). In some cases I would maybe consider the cost to turn the conversion back into a garage – especially if the conversion was shoddy or minimal to cure. Still other times I might ponder the cost to permit the conversion or the cost to actually build a garage if there is space to do so. Remember, the adjustment at $15,000 made sense here, but it could be FAR DIFFERENT in other situations.

Garage Conversion Video: This audio clip is ten minutes or so and could be good as background noise while working. Watch below (or here).

Note on permits: As an appraiser it’s a liability to assume everything in a non-permitted conversion was done to code. What if I recognized value for a conversion but then in the future an owner had to rip out the non-permitted area? Can you see why some appraisers (and lenders) won’t give value to something unless it was permitted? Yet we still have to ask, “Is the market willing to pay something for this non-permitted area?” This is not an easy question to answer, but it is vital nonetheless. Hopefully we can find some comps, but more than that we need to disclose everything clearly, use logic and professional judgement, and maybe reach out for opinions of other trusted professionals too.

Questions: How do you deal with garage conversions? Any other insight? Did I miss something? I’d love to hear your take.
