Tiny Sleeping Space Code Issues

I designed a residential accessory building in Portland, Oregon that was built seven years ago that’s tall and skinny and has a tiny “room” at the top, ostensibly for sleeping, though I never addressed it as a sleeping space, and we labeled it as storage for code review – the client called it the “Crow’s Nest”. The “Loft” bedroom area that you can see labeled on the plan had a custom bed with drawers underneath, as did the Crow’s Nest. The owner had a cabinet maker design and make the beds, and, to my surprise, both beds were installed before final inspection, and the project passed all finals.

The Crow’s Nest is 37 s.f. and does not have a 5.7 s.f. egress window.

The intended use of the structure was as an Airbnb, and it was designed so it could be converted into a legal ADU in the future (no kitchen currently – no second kitchens allowed). The accessory building was approved shortly after completion for use as a short-term rental, and rented continuously up until one year ago when the owner sold the house and accessory rental building. The new owner got a temporary permit to continue its use as a rental, and when that expired, the City reviewed the original floor plan that was on file and caught code violations – the second story was labeled "Loft" not "Bedroom", and, as it could be now “seen” in the pictures on the Airbnb website, it clearly had a bed in both the loft space and the storage space in what was now an unapproved use – at the time it was originally permitted, accessible “lofts”, or, more precisely, sleeping lofts, were not allowed/addressed in the code (at least I can’t find it, and, despite emailing the City twice asking what the term loft meant in 2015, no one has responded to that specific question).

The labeling of the space as “Loft” was an oversite on my part – this space was intended and believed to be a bedroom by all involved, except possibly by the original plans examiner. I’ve made a bedroom labeling mistake many times on residential plans, where, when you are creating schematic design drawings for clients, you often label rooms for presentation, not for permitting, then forget to change the room name/use. A typical one I’ve been called on is labeling a room a Study, where, to the plan’s examiner, it’s over 70 s.f. and has a closet, so it’s obviously a bedroom and must be renamed and be verified as code compliant. Fair enough – it could be used as a bedroom in the future, so let’s make it official.

In this case, the room label fix is easy – the plans can be resubmitted with the changed name and re-inspected. Since it was both designed and inspected as a bedroom originally, I know it will pass. The storage/crow’s nest is a potential problem and the City only stated its size while containing a bed as an issue in their written code compliance email.

That’s the background and what triggered the current owner to contact me.

I cannot say why the original inspector passed this as legal with the beds present, except that the contractor apparently did not yet have the door on the “storage” space (or, maybe, did that on purpose). What I’m wondering is, could we now make an argument that the space is a sleeping niche if it did not have a door - the inspector can’t see whether it currently has a sliding door in the Airbnb listing pictures and it can be permanently removed?

I’ve created two sleeping alcoves/niches for kids’ bedrooms in my career. We walled in part of the front to make them cozier. They both had a wider opening than the Crow’s Nest and no floor space, but one of them had bunk beds and a ladder to the upper portion (making it a loft?) – and all were built-in, and, as with this current case, no inspector said a thing.

Has anyone encountered anything similar with a small bed space like this? And, more specifically, if the upper “storage” space is in a room-on-room configuration with no door and just barely big enough for a bed, can you tell me why a code official could not count it as another part of the bedroom? I don’t know whether this is simply a judgement call by a code official or whether the door requirement for a sleeping space is addressed somewhere in the code – I have not found it specifically addressed in the code yet.

If anybody wants to say, tsk-tsk, why did you design this in first place, I cannot really justify it, except to say, the owner really, really wanted it and all I gave her was a well-lit closet.

At the time, we looked to Seattle’s proposed code for tiny homes (we kept this home just under 400 s.f.) with lofts and followed their area and ceiling height limitation. Neither that 2015 model code nor the recently passed IRC sleeping loft code addresses a door, so I assume all lofts have to be open to the adjacent space to be allowed?

In 2015, this was the seventh loft I had designed for an ADU (not short-term rental) and several of those lofts had their ship’s ladder, a non-code compliant stair, installed at final, and no inspector said a thing. It was apparent that the building department had a liberal/tolerant attitude toward potential sleeping lofts. I always omitted the access ladder on any plans, so all my designed only had the potential of a sleeping loft.

Even with my own home, where I built a large insulated attic that has an alternating step ship’s ladder, at final, the inspector opened the attic door and saw the stair (with no landing at the bottom) and complimented me for installing a handrail and did not go up to look and then just shut the door. Obviously not the same thing as a short-term rental sleeping loft, but it has the same potential.
 

 
Would not pass as any kind of habitable room in my state. Would not comply with the minimum size requirements per 2018 IRC. I have failed this when added for a short-term rental house.
 
I've had a few applicants try this (Canadian codes) and the issue has usually been the big-nasty building inspector/plans reviewer crushing the clients' dreams by pointing out that if the space is habitable (ie: the ceiling height meets the threshold for a room) its access has to be Code-compliant stairs, not ladders.

Someone in the future who runs down those stairs to escape from a house fire is going to thank the big nasty building official for doing their job.

Do you know in the code whether a room for sleeping needs a door? Again, I'm looking at this as a niche off the room. Since people make sleeping niches, those interpreting the code must know when such a niche breaks the threshold and becomes a separate room. What is that threshold in your jurisdiction?

In this case, the short section of spiral stair to the Crow's Nest is code compliant for egress.

In referring to sleeping lofts, I was merely pointing out that the room otherwise met the current requirement for a sleeping loft as defined in the IRC Appendix P.

What I'm not sure about is, can their be a door to a sleeping loft - or, is not having the door a requisite for counting the loft as part of the adjacent space?
 
I've not seen the floor plan of the space below, but I assume it has either a window or an exterior door that complies with emergency escape requirements.

So if the barn door was removed to the "storage" space, then it, along with the "loft" is all one giant odd-shaped room, and the exterior door could serve as the emergency escape and rescue opening.

Next, without a door, the "storage" has at least 7' in the left-right direction and it might barely have 7' as measured to the panes of glass (like a BOMA calc) in the up-down direction.

Looks like the ceiling is sloping, so you only need min. 7.5' of headroom in 50% of the combination storage+loft area. If it meets that, then the storage+loft+ space below may comply as a single bedroom. I don't think it will comply as two separate bedrooms.

It's funny, there are people who live in smaller spaces like this all the time on boats and in 5th wheel RVs and it is not considered "unsafe". Heck, in many houses there are code-compliant bedrooms stuffed with furnishings that effectively make them as small or smaller than the crow's nest clear walking surface area, and those freestanding furnishings could topple over in an earthquake.

IRC 2018 and IRC 2021 both include an Appendix Q that addresses tiny homes (under 400 square feet). It isn't mandatory, but (unless Appendix Q is removed when a jurisdiction adopts the IRC) it can be invoked when it applies.

Code in Canada deals with this under "combination rooms"

Two or more areas may be considered as a combination room if the opening
between the areas occupies the larger of 3 m2 or 40% or more of the area of the wall
measured on the side of the dependent area.

Appendix Q has not been adopted in PA and probably won't in the 2021 IRC next year. Don't know if locals can adopt it.
 
Only if PA adopted chapter one of the code. Specifically R104.11 Alternative materials, design and methods of construction and equipment.
 
Case-by-case modification doesn't come from R104.11, it comes from R104.10 (2021 IRC):

R104.10 Modifications. Where there are practical difficulties
involved in carrying out the provisions of this code, the building
official shall have the authority to grant modifications for
individual cases, provided the building official shall first find
that special individual reason makes the strict letter of this
code impractical and the modification is in compliance with
the intent and purpose of this code and that such modification
does not lessen health, life and fire safety or structural requirements.
The details of action granting modifications shall be
recorded and entered in the files of the department of building
safety.

According to UpCodes, Pennsylvania preserves that provision of the IRC:

R104.10 Modifications​

Pennsylvania also adopted Appendix AQ. Granting a modification based on an adopted appendix to the code should be a no-brainer.

The space below meets all egress requirements, as does the Loft - the spiral stair is the minimum width for egress.

Making the Loft plus the Crow's nest one space would be the argument as to why a bed should be allowed as is.

I'm curious where the 7' horizontal dimension comes from - is that written in the code somewhere?

A note to all - this is not a separate dwelling unit, so my mention of tiny homes rules applies if, in the future, the owner decides to make it an ADU. I only mentioned the 400' goal in my initial post because that was part of our long-term thinking, but those thoughts were based on a yet to be defined code in 2015.
 
2018
R304.1 Minimum area.
Habitable rooms shall have a floor area of not less than 70 square feet (6.5 m2).

Exception: Kitchens.

R304.2 Minimum dimensions.
Habitable rooms shall be not less than 7 feet (2134 mm) in any horizontal dimension.

Exception: Kitchens.
 
R104.11 2018, forgot to include the edition
Here in Portland, Oregon, we have a lot of Craftsman era houses that were originally single story with an unfinished attic under a bungalow style low-sloped roof. People later converted those to finished bedroom spaces. When you attempt any major modifications to the house, the City calls out the unpermitted attic conversions, but has always allowed existing improvements on Appeal - this is with bathrooms, way too steep and skinny stairs, and non-egress sized windows.

In this case the work is new, so the arguments of longevity and work (possibly) done before code rules where adopted won't count here - that is, despite the fact that these spaces where officially approved previously and used as a short term rental for seven years won't hold any weight with the City. The owner will have the City out for inspections, so eventually we’ll see what they say. Right now, the City is simple saying the Crow's Nest was not approved for its current use, despite the fact that it was approved.

What I'm looking for is where in the code does it define when a room becomes a separate room. The loft code rules are specific and may only apply in tiny homes - and potentially only in tiny homes on wheels.

I've heard that part of the reasoning to allow for lofts is that the total distance to an exit is very short in such small dwelling spaces. That reasoning could apply here too in an appeal, but, as I don't have to tell anyone who is a code official, despite any flexibility they can exercise, there is always a line that can't be crossed - I want to first see if there is any line here at all before we present any arguments.

Another thing we have going against us is that the City scrutinized this project at submittal in an unprecedented way - too tall and skinny for a small city lot for their likings, and the City is not pro short-term rentals generally. Despite their objections, it met all code and planning requirements. It was meant to be a pseudo-treehouse (not attached to any adjacent trees) and a folly fulfilling the owner's childhood dreams - and, apparently it makes a great rental so it fulfils others' fantasies too and has gotten all five star reviews from guests who've stayed (one four star from someone who had to cancel and did not get a full refund).

Thanks for the reply. We know we can't make the argument that is a habitable room. I thought that Yikes may have been pointing out some other criteria - say, for a loft classification.

Yes, I find the minimum room dimension requirement is not well-phrased. If the phrase "in ANY dimension" is taken literally, no bedroom that is shaped like the one below could ever be allowed because it is noncompliant in at least 4 dimensions:

Yes, I'm saying that once you remove the barn door, if there are no other doors between the crow's nest bed and the exit door, then the downstairs+upstairs (including the crow's nest) is treated as one big habitable bedroom / studio. The downstairs exit door serves as the EERO for the sleeping area as well as the primary exit.

I have not seen your downstairs plan, so I don't know if that is the actual condition.

I daresay that perhaps the barn door could probably be replaced with a curtain and it could still be made to comply with code.
 
Here's how you get around code minimum sleeping space requirements:
I searched for the Airbnb listing for the "Treehouse" I'm posting about here, and it looks like the owner has taken it down for now. I did a general search for Portland treehouse Airbnb, and came up the this - https://www.airbnb.com/rooms/37327407?source_impression_id=p3_1691761545_wBVbRiqKjjiWTftp

It looks like the treehouse (a real treehouse in this case), could possibly be less than 200 s.f., and, in Portland, there are no code requirements for structures less than 200 s.f. - there are height restrictions and you can't sleep in them under any circumstances (unless you are in an official homeless "village"). They have the code compliant sleeping space be in their house. I'm willing to bet people sleep up there, but it's a tough to get to the bathroom!
