Highest And Best Unit Vs. Permits: An Official Response From Fannie

:)

Just had a conversation (minutes ago) with an appraiser who is working with Fannie & Freddie on the ADU issues and likely changes to come. "legal use" vs. "Illegal use" was part of that conversation and, no surprise, the FANNIE reconfirmed their position to which I originally posted.

I can guarantee you that no client/lender considers a non-permitted alteration that would be permissible under the current zoning regulations to constitute an illegal use.
I can further strongly affirm that all the savants I know in regards to H&BU (and, I know a few) do not consider a non-permitted alteration that would be permissible under the current zoning regulations to constitute an illegal use.
I can state factually that the regulated institutions with whom I do review work for (which includes USPAP and IAG compliance) do not consider a non-permitted alteration that would be permissible under the current zoning regulations to constitute an illegal use.

But, Mike, you and I have had this disagreement for years. So there is nothing new here under the sun. :cool:

(I would like to compliment you, however. While we disagree strongly of this issue, you've always maintained the disagreement-discussion in a polite and professional manner. Many could learn from you on that!)

a lot of empty L&I folders in this city of 200 & 300 year old houses. i gotta start tracking down those original builders. hey ben franklin, what was that code on those basements. now we have information overload, and we argue about the legality of that finished rear shed. the past h&b use of it was the outhouse.
of course now, the city will shut you down, or lock you up, if you rehab a house without permits.
 
Hi Denis, just spotted this thread. Thanks for the compliment and back-atcha. :beer:

To further the discussion, let's visit One City in CA as an additional example:

Wonder what those same folks, and potential Property Buyers, would believe after visiting the Shamrock City in CA, and having the Lender's Legal Department Chief Counsel review:

http://dublinca.gov/723/What-Is-A-Code-Violation

and then

the Shamrock City's Building Code (codified into Law)

7.28.060 Illegal building, structure or installation.

7.28.170 Discontinuance of utilities—Authority.
A. The Building Official may order the discontinuance of the supply of electrical energy, fuel gas or water to any building or structure, electrical, plumbing, or mechanical installation which is:


1. Being occupied or used contrary to the provisions of this chapter or any other applicable law, ordinance, rule or regulation;
2. A dangerous building or structure, or dangerous electrical, plumbing or mechanical installation;

3. An illegal building or structure, electrical, plumbing or mechanical installation; or

4. A substandard building.


B. Such order shall be in writing and shall state the nature of the condition requiring the discontinuance of utilities and the time when such utilities shall be discontinued. The order shall be directed to the person supplying electrical energy, fuel gas, or water and a copy of said order shall be sent to the person using said utilities and to the owner of the premises. (Ord. 12-16 § 3 (Exh. B) (part): Ord. 25-10 § 3 (Exh. B) (part))

and also read through the BC Chapter 8
Sections 8.144, 8.144.050 A & D,
8.144.060 A & B, 8.144.070 B,
8.140.080 and 8.140.060 :shrug:

Then visiting County and State similar Laws/Ordinances as well.

There has been a continuous, running gun-battle between a small contingent of appraisers on this forum and others regarding how one should address a non-permitted component of a house in regards to H&BU analysis when completing an assignment that needs to comply with the Fannie Mae guidelines.

The argument, simplified, is this:
The "use" consideration in H&BU analysis concerns itself with what kind of use is legally permissible. In other words, if a SFR is legally permissible, than an SFR on a site is a legal use. SFR = USE.​

The counter argument is:
If the SFR has a non-permitted alteration, then that non-permitted alteration constitutes an illegal use. If permits are required, and no permits were obtained, then the use becomes "illegal" until such time when permits are obtained.​

The consequences of concluding that a non-permitted alteration creates an "illegal use" should be apparent: If that is the conclusion, then a property with, say, a non-permitted room addition or even a non-permitted kitchen remodel would be checked "Illegal use" and, thus, not be eligible for GSE purchase.

Notwithstanding that none of the recognized literature indicate that the lack of permits for an alteration to a legally permissible use creates an illegal use, this argument on this forum persists. Obviously, appraisers who engage in GSE work should have some clarity and confidence in what they do in regards to their H&BU analysis and how to address non-permitted alterations.

I contacted FNMA and asked them about this issue. I was given permission to summarize the response and to reference that this came directly from an authority at FNMA. For what it is worth, this authority has been with the GSE for a number of years, and our email exchange was CC'd to another member of FNMA, so this isn't a lone wolf response/one off.

Here is my original email:

Hi:​
I’m hoping that you can point me in the right direction (by forwarding this inquiry) or by telling me who I can contact direct.​
There has been a small change in the 03/29/2016 Selling Guide (Section B4-1.3—04) regarding the Highest and Best Use Analysis. I appreciate that this is a very technical appraisal/appraiser-orientated question but it is causing some uncertainty in our profession. On page 600-601 of the Selling Guide, a discussion of Highest and Best Use is included. Here is the excerpt which I’m asking about:​
The appraiser determines highest and best use of a site as the reasonable and probable use that​
supports the highest present value on the effective date of the appraisal. For improvements to​
represent the highest and best use of a site, they must be legally permitted, financially feasible,​
and physically possible, and must provide more profit than any other use of the site would​
generate. All of those criteria must be met if the improvements are to be considered as the​
highest and best use of a site.​

I’ve bolded the specific item in question. Previous Selling Guide versions used the term “legally permissible”. The new language is “legally permitted.” Let me tell you why I’m asking for clarification.​
There are some appraisers who interpret “legally permitted” to mean any alteration or change to the house which would require a building permit to do so and one was not obtained, to now cause the house to be identified as an “illegal use”. An example:​
- A house has modified its 4-bedroom configuration to a 3-bedroom configuration, and has removed a window. Removing of the window required a building permit and one was not obtained. An appraiser asks for permits, does not receive any, and now indicates the home is an “illegal use” and thus, the loan is ineligible for FNMA.​
Historically, the permissibility of the “use” in the context of Highest and Best Use (H&BU) has been: Does the zoning ordinance/authority allow a residential home on this location? Historically, the significant question was to determine if a property is zoned as something else (commercial, for example) and the improvement is really a commercial improvement and not a house. With this small change in the language, some appraisers are arguing that “permitted” now means that any change to the improvement that would require a building permit (bath remodel, kitchen remodel, etc., etc.) and does not have that permit will create an illegal use.​
I know, it may sound ridiculous to a non-appraiser, but this contingent, while in the minority, exists. I find it hard to believe that this was the intent of the word change and I find it hard to believe that a kitchen remodel which should be done with a permit now makes the house ineligible for a FNMA loan. But, I’m the one that could be wrong.​
Please, if you can, provide some guidance on this. Please recognize that a small change in your wording gets interpreted 50,000 different ways out here in the field; sometimes correctly and sometimes incorrectly.​
If someone responds and tells me, “Denis, you are correct. We are talking about permitted uses and not a permitted renovation. We don’t want commercial properties being appraised as houses, etc…” I will do my best to pass on the word. An official clarification, as small and ridiculous as it may seem to you, would go a very long way on our side.​
Thanks in advance for any help/assistance/clarification you can provide.​
[end of Denis email]

Here is the summarized response (the italicized word is from the communication I received intended to emphasize the point. The bolded part is my own emphasis that identifies how FNMA differentiates between the question of a legally permissible use and permits):

The intent of our H&BU policy is to be consistent with the 4-tests (physically possible, legally permissible, financially feasible, maximally productive). It is not meant to be applied to improvements that are not permitted (not built to code). We have a policy on permits (B4-1.3-05, "Improvements Section of the Appraisal Report 09/29/2015). That policy states:​
If the appraiser identifies an addition(s) that does not have the required permit, the appraiser must comment on the quality and appearance of the work and its impact, if any, on the market value of the subject property.​



The authority also added in that his many years at FNMA, he has not heard that misinterpreting the H&BU section to include "permits" was an issue or had been questioned. There is no question, based on the response I received in full, that permit issues are not what is part of the "legally permissible" or "legally permitted" portion of the H&BU policy. None whatsoever.


My desire is to disseminate this information to assist anyone who is uncertain about this issue. If anyone still has questions on how to proceed, I suggest they do their own research.
Thank you but the problem is especially for residential appraisers, since they have no previous experience in development, construction or how entitlements are obtained, they have no idea how to apply H & B use except based on a zoning code they get off realist. General plans, overlays , specific plans no idea . We -were much better off when years ago they checked the box-- because 90% are not qualified to even deal with it ... NOW I will get my butt kicked by all the residential appraisers who feel slighted : ) LMAO

To say that something must "be legally permitted" is not the same as saying that it must have a legal permit. That is a kind of logic error. - I think the error is in writing the regulation. It is ambiguous. When you say something "must be legally permitted", do you mean in the sense that it must conform to building codes or actually have a permit? That is to say, "permitted" can mean "allowed" or "actually having a permit". Whoever wrote the response from Fannie Mae, did not answer the criticism/question directly, but only in a roundabout way.

So, there is nothing in the reg that is a problem. And, Fannie May does have a "policy on permits."

Another question is whether the appraiser is in a position to decide whether something is "legally permitted." Well, to this we might inject the sporadic existence of grandfathering provisions in some districts. Owners can apply for waivers. And, if a building permit is granted, even if the construction runs counter to building code, it is nonetheless "legally permitted" - because it has a permit. All the appraiser can do is make note of it in his report, per the Fannie Mae guidelines. Then again, if it is clearly egregious in the extreme, he might make it boldface, red and large type.

Correction: There is something wrong in the Fannie Mae regulation of course: "be legally permitted" should be replaced by "legally permissible", also noting per the 14th Edition of "The Appraisal of Real Estate", page 332, that HBU, "reasonably probable use" requires satisfying the condition "The use must be legally permissible (or it is reasonably probable to render it so)."

I would also add that "legally permissible" is not defined in USPAP, the "Data Dictionary of Real Estate", 6th Edition, or even "The Appraisal of Real Estate". Let me suggest it is a messy term that mixes up:

1. Whether a use complies with existing building codes, or just building codes at the time of construction with legality through grandfathering provisions
2. Whether the term assumes that a legal permit was or could be obtained.
3. Whether the term includes waivers that render the property legal in the eyes of the local building officials, even though it is not, nor ever was legally permissible according to building codes or other regulations. [Note that whether a modification or feature "could be" waivered as a variance often depends on the request being made through a public hearing, including invitations to owners of neighboring properties and a vote by the planning commission.).]
4. To what extent the appraiser is allowed to use his own judgment in deciding whether modifications or features could be made legally permissible through any of the above..

To the above 4 points, we really need a new term, such as "legally permittable", which however may, in fact, may not carry much weight since waivers (aka variances) allow potentially wide latitude.
 
So for 4 years we keep reviving this thread? I don't get it.

USPAP has been getting "revived" every two years for decades now. It still has many ambiguities, numerous contradictions, lacks definitions and logical rigor, and has a poor structure (e.g. the SOW regulations) that invites additional problems, all of which have a negative ripple effect on the entire appraisal industry.
