Do not miss the above parody video on Portland tiny
homes. It is the hilarious and the perfect
introduction for an article on Portland accessory dwelling units.
An accessory dwelling unit (ADU), also known around
Portland, Oregon as “granny flats, mother-in-law apartments, and carriage
houses” is a second residential living unit on an existing single-family home
site. ADUs became popular in Portland in
2010 after the city waived many development fees as a way to increase density
and affordability. Portland ADUs come in
many shapes and sizes. An ADU can be created
by building a small detached home next to (but a minimum of six feet away from)
an existing home, by adding an attached unit onto the existing home, or by converting
a portion of the existing home, garage, basement, or attic into a unit.
Appraising ADUs is difficult because each is unique and because
there are often few comparable sales of other accessory unit properties. Additionally, it is common that ADUs have
been built without proper permitting, and income from accessory units is not
directly comparable to other more common income properties such as apartments
or small detached homes. Rather than
write a book about appraising accessory units, here is a list of some
interesting appraisal-related facts about ADUs in Portland.
residential zones in Portland allow for accessory units. This means that when an appraiser considers
the highest and best use of a property in Portland, adding an accessory unit
should be a legally-permissible consideration.
2. In the
City of Portland, ADUs and the main house can usually be legally rented, just
as with a traditional duplex. However, many of the municipal areas surrounding Portland
do not allow renting. It is important
for appraisers to understand the legal uses of the ADU because that could
change the type of buyers who would be interested in the property.
Portland, ADUs cannot exceed 800 square feet or 75 percent (including basement)
of the main home.
kitchen defines an accessory unit in Portland.
Simply having a bedroom or a second living space is not considered an
accessory unit. Also, ADUs do not
require the separately metered utilities or additional parking that are common
with a typical duplex.
ADUs in Portland were created outside of the permitting process. Such units may be unsafe and might not add
value to the home. Legally permitted
ADUs can be extremely valuable and many are becoming more valuable with the
popularity of the “tiny home” and the proliferation of vacation rentals like Airbnb.
accessory units will have very high site development costs due to sidewalks, permits,
the need to match the existing home, utilities, and such. Builders have indicated to me that a person
can spend $50,000 before even beginning construction of a detached unit.
building an accessory unit, your entire house could become subject to
additional tax due to reappraisal of the whole property and not just the
addition of the accessory unit. (Click
here for a recent article that shows citizens are upset about this
and that reappraisal requirement might be changing in the future.) However, remember that tax laws are complex. Anyone considering building an ADU should
first consult with the assessor.
lenders often are not experienced with providing loans on homes that have ADUs,
nor do many appraisers have experience with valuation of them. These two factors, combined with very few
comparable sales, different ways for appraisers to report appraisals of homes
with ADUs (as a Duplex on a 1025 form or a Single Family with ADU on a 1004
form) can make it challenging to refinance or purchase a home with an ADU. If you need to get a loan on a home with an
ADU, I recommend the following.
a. Find a
lender with experience in ADUs and income-producing properties. Often local credit unions will have more
experience and offer loan options for borrowers with ADUs.

you’re an appraiser, it is important to openly discuss the ADU appraisal with
the client before accepting or proceeding with the assignment. Lenders who do a lot of loans for ADUs will
often have a specific list of appraisal requirements to follow when appraising
ADUs. Following lender guidelines will
help appraisers avoid the problems and delays that come from client
expectations not aligning with the final appraisal product.

Thanks for reading,
I received a call recently from a Portland area real estate agent asking how a basement kitchen, installed by the homeowner without going through the usual building permit process, will affect the appraisal of her pending sale. Basement kitchens are typical around Portland, are attractive to many homebuyers, and often are not “permitted.” Issues with unpermitted areas are complicated, are much more of an issue now than in the past, and can come down to the discretion of the lender or the appraiser. However, remember that the appraiser is just reporting the facts to the lender and analyzing the marketability of those facts. The lender is concerned with liability of an unsafe improvement and the value of the collateral. Here are five factors to remember with regard to a basement kitchen.
A basement kitchen that is not permitted could be a hazard due to fire or ventilation and therefor a liability to the lender. This is usually only a factor when there is a freestanding or built-in stove or oven. Basement kitchen sinks and refrigerators typically are not seen by lenders as risky. If a range or oven is identified as not permitted or unsafe, the lender will typically condition it to be brought up to code (or outright removal) prior to funding of the loan. The appraiser will usually be asked to return and certify that the work is completed.
The appraiser is not an expert in building code. However, the appraiser should understand local building codes enough to recognize visible issues, should research codes with the appropriate authorities, and should communicate results to the client. Basement kitchens usually require electrical, mechanical, or plumbing permits that are in excess of the normal building permit to finish a basement. Asking the right questions is important.
It is not the appraiser’s responsibility to report code violations to authorities. Appraisers have a strict ethical responsibility of confidentiality. When querying local building officials (rather than saying, “This property has a basement kitchen”), the appraiser might ask, “What permits would be necessary to install a kitchen in the basement of the subject?”
The appraiser should take plenty of pictures. A simple appraiser photograph might put a nervous lender at rest because the photo shows that there is no stove or range.
Most lenders or appraisal management companies have specific instructions for an appraiser to follow when dealing with unpermitted areas or basement kitchens. An appraiser should alert the client about issues like a basement kitchen prior to delivery of the appraisal, to make sure that lender protocol is followed.

I often have discussions with other appraisers and property owners around Portland, Oregon about the difficulty of appraising vacant land. Many are surprised that it can be more difficult to appraise property without a home than with a home. There are several principal reasons for this.
When appraising vacant land, there are typically more feasible options to explore about, “What is the highest and best use of the land?” This is because, when there is already a house built (one that is in good condition) in an area of similar homes, it is usually easy for the appraiser to see that it would not be feasible to tear down the existing structure and build something different. However, with vacant land there may not be any homes around it, or the homes that are around the land are old and are no longer the ideal improvement for the current real estate market. The phrase “highest and best use” is important in appraising because it tells us what sales are comparable. A similar looking tract of land might be maximally productive to build a duplex, rather than a single-family residence. We would not want to compare that duplex site to property that it is more suited for a single-family residence.
Since the highest and best use question may not be obvious for vacant land, the market analysis tends to require more detail. This means that an appraiser might not only need to know the trends in vacant land sales, but also the trends in new construction sales. For example, the appraiser should know what builders are building, what prices builders are receiving, and how much competition there is with different types of improvements to help estimate the ideal improvement for the subject vacant land. This kind of detailed market analysis is important with vacant land because most buyers of residential land are looking to answer the question, “How much profit will I make if I build and sell a house that costs X on this property?”
Often there are unknowns for the subject vacant land and comparable sales of land when it comes to cost for septic, well, road improvements, legal cost of obtaining easements, special foundations, and so forth. For example, many times I come across land sales that outwardly appear to be the same as the subject property. However, after interviewing the parties to the transaction, I find that the comparable development required utilities and road improvements (including sidewalks) to be installed. These represent a cost that the buyer of the vacant land acquires that may not be precisely known at the time of purchase. Therefore, the buyer of the vacant land must factor a risk premium into the purchase price that accounts for time and unknown costs. Appraisers call that risk “entrepreneurial incentive.”
In addition to all of the above, land is particularly difficult to appraise in Portland, Oregon and many of the surrounding suburban and rural areas because there are fewer overall comparable sales. Vacant land does not tend to sell as often as homes and there is now very little vacant land available to build on around Portland. Therefore, where a typical home may have several similar properties within a one mile radius, a vacant piece of land might require searching Portland’s entire east side for similar sales. To make matters worse, many vacant land sales occur outside of the local multiple listing service as a result of builders approaching land owners or because of “across-the-fence” deals. Finding and verifying these sales through vague county records data can be extremely tedious and time consuming.
