Enclosed pation and emergency egress

[Rio]

We have an semi asbuilt situation that we are in the process of getting permitted (contractor got caught). The contractor wants to call it an enclosed patio and we could design it that way by opening up the walls to 65% following the guidelines as set down by the city of San Diego and the CRC/IRC but after reading the below and considering where it is constructed (enclosing the front door) I thought it would have to be open; however after reading the provisions of Section R310, which covers entry doors among other items I'm thinking now that if the door to the enclosed patio is 36" wide by 80" high it will comply.

From Appendix H, patio covers

SECTION AH105

LIGHT AND VENTILATION/EMERGENCY EGRESS

AHlOS.l General. Exterior openings required for light and

ventilation shall be permitted to open into a patio structure

con-forming to Section AH101, provided that the patio structure

shall be unenclosed if such openings are serving as emergency

egress or rescue openings from sleeping rooms. Where

such exterior openings serve as an exit from the dwelling unit,

the patio structure, unless unenclosed, shall be provided with

exits conforming to the provisions of Section R310 of this

code .

Did California adopt Appendix H?

R311.1 only prescribes travelling through garages not other types of non-habitable spaces.

With the factory made modular patio enclosure systems the windows, to comply with the 65% opening requirements, are fabricated to have all lights operable, so a slider is an XX not an XO and both are removable to provide the 65% opening. Remember you’re dealing with openings not just light.

Most of these manufacturers manufacture their windows in two heights using their own extrusions and fitting these into a conventionally constructed wall will be tricky.

Remember these are non-habitable rooms.

CA HCD did adopt Appendix H.

Did California adopt Appendix H?

Some municipalities adopted Appendix H some did not, its a crap shoot

TJAs noted above the CA state agency, Housing and Community Development, adopted Appendix H, meaning it was adopted statewide, local authorities may have amendments.

Apparently San Diego has because when I read Appendix H it's the same as the San Diego Information Bulletin
