Land Swap with US Forest Service must be complete prior to final approval and issuance of the਍ഀ Building Permit.਍ഀ The agreement was signed on January 18th, 2006 and is now in a 45 day review period.਍ഀ 2. When plans are resubmitted for review; complete sets of plans for each building which includes the਍ഀ addendum sheets. Separate addendum packets will not be accepted and approved for initial਍ഀ permitting.਍ഀ Plans have been modified and are to be resubmitted for the Town of Vail Building and Fire਍ഀ Department review, approval and issuance of a permit.਍ഀ 3. Preliminary plan review meetings had discussion regarding the submittal of Memorandum of਍ഀ Understandings (MOU). MOU's defined in these meetings would be "used to define or clarify the use਍ഀ of a code section, agreement to the installation of a system not covered specifically by the code or਍ഀ clarify the use or component of a building. None of the agreed upon MOU's were submitted for਍ഀ review. Please provide the following MOU's for review:਍ഀ a) Use of assumed property lines and fire separation distance.਍ഀ b) Fire command room਍ഀ c) Smoke management systems਍ഀ d) Opening between parking garage and Lodge Tower parking garage਍ഀ e) Fire separation between the new building and existing buildings਍ഀ f) Use of 508.2 for creating separate buildings as it relates to each building਍ഀ g) The separation between One Vail Place and new Skier Services਍ഀ A Memorandum of Understanding dated April 3, 2006 addressing these issues has been completed਍ഀ and will be submitted to the Building, Fire Department and Colorado Code Inspection for review and਍ഀ approval.਍ഀ 4. Preliminary plan review submittal meetings had discussion regarding the submittal of Administrative਍ഀ Modifications (AM). AM's as defined in these meetings would be based on International Building਍ഀ Code Section 104.10. Where practical difficulties are involved in carrying out the provision of this਍ഀ code, a modification to the code may be granted by the building official after justification that the਍ഀ modification will not lesson health, accessibility, life and fire safety, or structural requirements. The਍ഀ following AM's have been discussed and are being implemented into the plans. Please provide the਍ഀ following or amend plans accordingly to comply with the code.਍ഀ a) Separation between Chalet buildings਍ഀ b) Elimination of elevator smoke doors at residential levels of the Chalet buildings਍ഀ A Request for Administrative Modification dated April 3, 2006 addressing these issues has been਍ഀ completed and will be submitted to the Building, Fire Department and Colorado Code Inspection for਍ഀ review and approval.਍ഀ 5. Be sure to amend the Fire & Life Safety Report as necessary when changes are made to the plans਍ഀ that may affect the discussions made by the Report.਍ഀ An updated Life Safety Report for The Vail Front Door Buildings A, B, C and D dated April 3, 2006਍ഀ has been completed and coordinated with the G - Series Code Drawings. This report and਍ഀ attachments will be submitted to the Building, Fire Department and Colorado Code Inspection for਍ഀ review and approval.਍ഀ 6. Provide a precise site plan showing exact locations of assumed property lines. If locations of assumed਍ഀ property lines are close enough to exterior walls to require rating of walls and opening protection,਍ഀ provide details.਍ഀ C:ADOCUME-I\dhopp\LOCALS-I\Temp\E - Response to ToV-b06-0022 thru b06-0029.DOC Page 2 of 2਍ഀ 4240 has updated the G - Series Code Drawings indicating the locations of property lines and਍ഀ assumed property lines.਍ഀ 7. Fire and Life Safety Report states the use of 1-hour fire walls per IBC Table 705.4. This table does਍ഀ not allow for 1 hour fire walls anywhere. Please clarify.਍ഀ The Life Safety Report has been modified to reflect the approach taken for the building separations.਍ഀ As indicated in the report numerous meetings were held with the building and fire department਍ഀ identifying buildings, construction types and openings. The buildings and proximity to the property਍ഀ lines will not meet the prescriptive requirements of the building code. The design team has identified਍ഀ on the G - Series Code Drawings that the project will use a variety of 3-hour horizontal and vertical਍ഀ fire resistive separations as well as 2-hour and 1-hour occupancy separation walls. This approach of਍ഀ compartmentation with the use of automatic sprinkler protection and detection though-out will not਍ഀ compromise the life safety of the occupants.਍ഀ 8. Fire walls are called out in the fire and life safety report to separate buildings. What is the purpose਍ഀ and use of the fire walls and the separations? Is it to separate property owners?਍ഀ It appears that fire separation distances are being used to determine the ratings for the walls਍ഀ identified as fire walls between the different building and spaces. Our interpretation of this section is਍ഀ that once the 3 hour separation is used to make a separate building then everything that is not਍ഀ separated by a fire wall per 705.4 will be considered as one building.਍ഀ The Life Safety Report has been modified to reflect the approach taken for the building separations.਍ഀ As indicated in the report numerous meetings were held with the building and fire department਍ഀ identifying buildings, construction types and openings.

Accessibility requirements do not appear to be included within any plan for this rojed- PTease -਍ഀ amend plans to include the following: i਍ഀ a) Accessible parking spaces and loading zones.਍ഀ b) Accessible route from the parking and loading zones to the buildings. i਍ഀ c) Accessible routes to each building on the site which are required to be aces '~'"^9.ORADO INSPECTION਍ഀ d) Signage details for parking, striping, routes, restrooms, etc. AGENCY਍ഀ e) Restroom details for fixtures, grab bars and accessories.਍ഀ The drawings have been modified to show accessible parking spaces and loading zones, accessible਍ഀ routes and confirmed that restroom details for fixtures, grab bars and accessories has been provided.਍ഀ All signs related to accessibility are listed in a separate contract with the client and will be a deferred਍ഀ submittal to the building for review and approval.਍ഀ 10. Amend plans to include stair signage plan, details and identify the location of the signage. Many of਍ഀ the exit enclosures require the occupants to travel up to get to exit discharge. Clearly identify the਍ഀ direction of travel to the exit discharge.(IBC 1019.1.6)਍ഀ The design team will modify the drawings to reflect required stair signage and directional signage. It਍ഀ would be the intent of the design team to identify with the fire department additional egress signage or਍ഀ directional signage to ensure occupants will be directed to a an egress stair/passage way and to a਍ഀ public way.਍ഀ 11. Amend plans to include gates located at the level of exit discharge to eliminate occupants of the਍ഀ building from entering an enclosure and passing by the level of exit discharge. (IBC 1019.1.6)਍ഀ Gates have been added to the plans to meet this requirement and direct occupants to the exterior or਍ഀ from continuing below or above a level of exit discharge.਍ഀ CADOCUME-I\dhopp\LOCALS--I\Temp\E -Response to ToV-b06-0022 thru b06-0029.DOC Page 3 of 3਍ഀ 12. Elevator door which do not open into a lobby need to be provided with a smoke control door in਍ഀ accordance with IBC Section 715.3.5.3਍ഀ None of the elevators penetrate more than 3 stories.

E: Per A610 for window types with tempered glazing and reference building elevations for਍ഀ location of such window types.਍ഀ 14. The size of main elevator cars used for fire/emergency access needs to be determined by the Town਍ഀ of Vail Building and Fire Departments. Standard 24" x 76" required by code will not accommodate the਍ഀ stretchers used by emergency personnel. Please confirm the required size.਍ഀ The elevator cabs are currently designed to comply with the standard stretcher requirement as਍ഀ adopted by the code. In the case of the Chalets the elevator serves 4 levels or 3 stories. Based on਍ഀ that interpretation the stretcher accessible would not be required. The design team is providing a਍ഀ stretcher accessible elevator to each unit beyond what would be required by code. The current਍ഀ elevators will be 24x74 inches.਍ഀ Architectural Comments:਍ഀ 15. Floor plan on sheets A111 & A113 show units 1 A and 1 B with elevators 10 and 11. Elevators 10 and਍ഀ 11 serve Units 3A and 3B. Revise plans.਍ഀ Re.

The mechanical level above the parking garage has been classified as a mezzanine. This space਍ഀ exceeds 1/3 of the square footage of the parking garage. Reclassify the space as a second story and਍ഀ revise code analysis and plans to reflect change.਍ഀ Mechanical Level is now classified as a second story. Re. sheets G024, G028, and Fire and Life਍ഀ Safety Report. The drawings has been modified to classify the mezzanine as story with a 2-hour਍ഀ separation between the mechanical level and adjoining spaces. This area is actually separated from਍ഀ adjoining earth with an 8-inch concrete wall. The mechanical floor also has two exits to the level਍ഀ below.਍ഀ 21. The LSR states that there will be a 3 hour fire separation from the parking garage to the residential਍ഀ units both horizontally and vertically. The vertical separation is shown as a one hour on the plans and਍ഀ the parking garage does not have a complete separation from the mechanical room on the floor਍ഀ above. Sheet G023 and 024 don't show stair ES02 as a rated assembly nor does it list a wall type.਍ഀ Sheet M010 shows the wall type as an "R" wall assembly which is shown as a 2 hour wood framed਍ഀ party wall on sheet A 600. If the ceiling of the parking garage is being used for the 3 hour separation਍ഀ then the stairs going to the 2nd floor mechanical room from the garage and the large opening for the਍ഀ garage ventilation must be protected. Add opening protection to the garage ceiling below the਍ഀ mechanical room or revise plans showing extent of three hour separation to include ceiling of਍ഀ mechanical room.਍ഀ A Request for Administrative Modification dated April 3, 2006 addressing these issues has been਍ഀ completed and will be submitted to the Building, Fire Department and Colorado Code Inspection for਍ഀ review and approval.਍ഀ 22. Fire rating of exterior walls of the dwelling units has been removed on the addendum with a note to਍ഀ coordinate with the life safety report. LSR states on the conclusion # 5 that "The exterior walls of the਍ഀ two-dwelling areas constructed as one-hour rated from the inside only and that unprotected openings਍ഀ on these walls be unlimited in area. " This in accordance with Section 704.5 of the 2003 IBC and਍ഀ footnote f of table 704.8 of the 2003 IBC." Will these walls be constructed as one-hour rated protected਍ഀ from the inside? Coordinate plans with LSR.਍ഀ Based on Administrative Modification, the exterior walls of the two-dwelling areas are constructed as਍ഀ one-hour rated from the inside only and unprotected openings on these walls shall be unlimited in਍ഀ area. Refer to the Type "J" series walls keyed on the floor plans and detailed on wall type sheet਍ഀ A600, and to the exterior wall note on G026.਍ഀ 23. Addendum # 1 has changed location of rated walls separating the parking garage from adjoining਍ഀ spaces. Addendum has added separation to the storage areas in the garage but not the elevator਍ഀ machine rooms. The elevator machine rooms do however have 90 min rated doors shown on the਍ഀ schedule. The now rated storage rooms don't have protected openings. Coordinate door schedule਍ഀ with wall construction for all spaces being separated from the parking garage.਍ഀ Re. sheet G023, A103, door schedule. Wall ratings of elevator machine rooms and storage rooms਍ഀ have been revised and door ratings have been revised accordingly. A Request for Administrative਍ഀ Modification dated April 3, 2006 addressing these issues has been completed and will be submitted਍ഀ to the Building, Fire Department and Colorado Code Inspection for review and approval. These walls਍ഀ in accordance with the administrative modification and previous meetings will be rated one hour from਍ഀ the inside out only.਍ഀ 24. 2 hour party wall shows an STC rating of 66 and references WB 382 for the assembly. LSR਍ഀ references WP 3820 which has an STC of 55 to 59. Clarify.਍ഀ The reference on the drawing has been corrected to read WP 3820 with an STC of 66.਍ഀ CADOCUME-I\dhopp\LOCALS-1\Temp\E -Response to ToV-b06-0022 thru b06-0029.DOC Page 5 of 5਍ഀ 25. Window types on sheet A 61Q label egress windows as E2. These windows are located in the dining਍ഀ room. Bedrooms have windows labeled as E. All spaces used for bedrooms shall have one window਍ഀ approved for egress purposes. Amend plans to locate an egress window in all bedrooms.਍ഀ Required egress windows have been noted on the window schedule.਍ഀ 26. Show compliance with section 707.11 where boiler vents enter rated shaft.਍ഀ Re. A105. The shaft which contains the boiler vents terminates in a room having a use related to the਍ഀ purpose of the shaft. In addition, the room has fire resistance rating and opening protectives at least਍ഀ equal to the protection required by the shaft. Therefore, the location where the boiler vents enter the਍ഀ rated shaft is in compliance with Section 707.11, note 2.਍ഀ 27. Rated shaft called out on sheet A105 and MO 10. No wall detail has been called for this assembly.਍ഀ Provide detail of listed 2 hour assembly for the boiler vent shaft.਍ഀ Re. P/A600 for 2 hr listed assembly.਍ഀ 28. Sheet A700 stair detail 3 shows DN direction opposite of detail 1, 2 and floor plan sheet਍ഀ A103,105,107.਍ഀ Re. 3/A700, `DN direction' has been corrected.਍ഀ 29. Sheet A 103 & 107 reference cross section at grid between J.6 and HA as detail 2 on sheet A306.਍ഀ There is no sheet 306 provided. Revise detail to correct sheet or provide sheet A306.਍ഀ Re. sheets A103 and A107, section tag has been deleted.਍ഀ 30. Provide smoke door assemblies per section 715.3.5.3 at all elevators doors.਍ഀ See the added note on A700 and A701 indicating elevator doors to be 90 minute rated. An `S' rating਍ഀ is not required because these elevators serve less than 4 stories, thus do not require smoke control਍ഀ nor venting. A Request for Administrative Modification dated April 3, 2006 addressing these issues਍ഀ has been completed and will be submitted to the Building, Fire Department and Colorado Code਍ഀ Inspection for review and approval.਍ഀ 31. Update plans to show ventilation and access to void space between dwelling units and garage. (IBC਍ഀ 1203.3)਍ഀ These spaces do not meet the definition of crawl space as no earth exists below floor joists. No਍ഀ ventilation is necessary. Section drawings have been revised for these areas to indicate a layer of਍ഀ 5/8" type `X' GW B applied to the underside of the wood floor joists, creating a non-combustible਍ഀ envelope, as directed by TOV Fire Marshall, in order to avoid the need for fire sprinkler protection.਍ഀ Therefore no need for access to the void spaces is required. Furthermore it is our understanding that਍ഀ TOV Building Department prefers no access is provided in order to avoid potential occupant use of਍ഀ these spaces.਍ഀ 32. Provide ventilation to crawlspace areas in units. (IBC 1203.3)਍ഀ There no longer exist any crawl space conditions defined as where "space between bottom of floor਍ഀ joists and the earth" exists. No ventilation is necessary.਍ഀ 33. Provide details for protection of under stair areas in units if there is useable beneath the stair. (IBC਍ഀ 1019.1.1)਍ഀ IBC 1019.1.2 is not applicable. Per IBC 1019.1 Exception 3, a protected stairway exit enclosure is਍ഀ not required. Per IBC 1019.1.5 Exception 1, the space under stairways is not required to be਍ഀ protected.਍ഀ 34. Life Safety Report references the construction of the party wall between units as providing additional਍ഀ protection because the wall is being constructed as a two hour assembly. LSR states that the wall will਍ഀ continue to and terminate at the underside of the roof sheathing. This detail is not reflected on the਍ഀ C:\DOCUM&-I\dhopp\LOCALS-I\Temp\E - Response to ToV-b06-0022 thru b06-0029.DOC Page 6 of 6਍ഀ plans in fact it is shown stopping the wall at the underside of the rafters. Please coordinate the plans਍ഀ with the LSR continuing the wall to the roof sheathing. Provide detail for roof ventilation as wall to਍ഀ deck will eliminate ridge vent.਍ഀ A Request for Administrative Modification dated April 3, 2006 addressing these issues has been਍ഀ completed and will be submitted to the Building, Fire Department and Colorado Code Inspection for਍ഀ review and approval. Additional enlarged details have been added to the section drawings describing਍ഀ the rated walls where they intersect with the roof.਍ഀ REVIEWED BY਍ഀ COLORADO INSPECTION਍ഀ AGENCY਍ഀ CAD000ME-I\dhopp\LOCALS-1\Temp\E -Response to ToV-b06-0022 thru b06-0029.DOC Page 7 of 7਍ഀ 34a. LSR also states that they are utilizing section 705.7 of the 2003 IBC for combustible members਍ഀ entering the rated assembly at the party wall. The referenced section (705.7) is part of section 705਍ഀ "Fire Walls". This section is a very prescriptive commentary on the construction of fire walls one of਍ഀ which "705.3" states "Fire Walls shall be of any approved noncombustible materials. Section 705.7 is਍ഀ not applicable to the assembly being shown on the plans because of the combustible framing਍ഀ members used in the construction of the wall. Revise plans removing all framing members from਍ഀ entering the party wall or change the construction of the wall to meet section 705.3.਍ഀ A Request for Administrative Modification dated April 3, 2006 addressing these issues has been਍ഀ completed and will be submitted to the Building, Fire Department and Colorado Code Inspection for਍ഀ review and approval.਍ഀ 34b. The Chalet residences are not exempt from the requirements of accessible units. Per IBC Section਍ഀ 3104.2 exception 2 requires that connected buildings shall be considered as one building for the਍ഀ purpose of calculating the number of type B units is required by IBC Chapter 11. Amend plan to਍ഀ comply with Chapter 11.

It has never been the intent that the residential Chalets would comply with਍ഀ Chapter 11. The Chalets are considered to be a separate building from the parking garage below.਍ഀ This was discussed and presented to the TOV Building Department at meeting on September 22,਍ഀ 2006..The Meeting Minutes from that meeting are attached. At that meeting the question was raised਍ഀ with the TOV at the first Meeting that CIA attended. In those Minutes, you will see specifically see਍ഀ where the question was asked if Chapter 11 Accessibility requirements would be applicable for the਍ഀ Chalets. The consensus from the Group was that Chapter 11 of the IBC would not be applied to the਍ഀ Chalets.਍ഀ Mechanical Comments:਍ഀ 35. Provide manufacturers specs on fireplaces used in the residences. If fireplaces are open front and਍ഀ capable of burning wood all shafts for the vents must be constructed as 1 hour rated assemblies.਍ഀ Decorative shroud must be listed for installation with the appliance.਍ഀ Specification section 10305 has been added describing, Manufactured Fireplaces and Flues. Re.਍ഀ A471 and A600 for 1 hr shaft assemblies. 4240 is currently working with the fireplace manufacturer਍ഀ to satisfy this requirement for the shrouds.

Fire and Life Safety Report states the use of 1 hour fire walls per IBC Table 705.4. This table does਍ഀ not allow for 1 hour fire walls anywhere. Please clarify.਍ഀ 8. Fire walls are called out in the fire and life safety report to separate buildings. What is the purpose਍ഀ and use of the fire walls and the separations? Is it to separate property owners?਍ഀ It appears that fire separation distances are being used to determine the ratings for the walls਍ഀ identified as fire walls between the different building and spaces. Our interpretation of this section is਍ഀ that once the 3 hour separation is used to make a separate building then everything that is not਍ഀ separated by a fire wall per 705.4 will be considered as one building.਍ഀ 9.

Sheet G 023 shows the travel distance from the residential units passing through the garage and਍ഀ using the garage travel distance of 400 feet as the criteria. The limit for travel distance is based on਍ഀ the occupancy not the occupancy you pass through to get to an exit. The maximum travel distance for਍ഀ residential occupancies with an approved sprinkler system is 250 feet. Revise plans to reflect the਍ഀ correct design distance per the occupancy served.਍ഀ 20. The mechanical level above the parking garage has been classified as a mezzanine. This space਍ഀ exceeds 1/3 of the square footage of the parking garage. Reclassify the space as a second story and਍ഀ revise code analysis and plans to reflect change.਍ഀ 21. The LSR states that there will be a 3 hour fire separation from the parking garage to the residential਍ഀ units both horizontally and vertically. The vertical separation is shown as a one hour on the plans and਍ഀ the parking garage does not have a complete separation from the mechanical room on the floor਍ഀ above.

Fire rating of exterior walls of the dwelling units has been removed on the addendum with a note to਍ഀ coordinate with the life safety report. LSR states on the conclusion # 5 that "The exterior walls of the਍ഀ two-dwelling areas constructed as one-hour rated from the inside only and that unprotected openings਍ഀ on these walls be unlimited in area. "This in accordance with Section 704.5 of the 2003 IBC and਍ഀ footnote f of table 704.8 of the 2003 IBC." Will these walls be constructed as one-hour rated protected਍ഀ from the inside? Coordinate plans with LSR਍ഀ 23. Addendum # 1 has changed location of rated walls separating the parking garage from adjoining਍ഀ spaces. Addendum has added separation to the storage areas in the garage but not the elevator਍ഀ machine rooms. The elevator machine rooms do however have 90 min rated doors shown on the਍ഀ schedule.

Life Safety Report references the construction of the party wall between units as providing additional਍ഀ protection because the wall is being constructed as a two hour assembly. LSR states that the wall will਍ഀ continue to and terminate at the underside of the roof sheathing. This detail is not reflected on the਍ഀ plans in fact it is shown stopping the wall at the underside of the rafters. Please coordinate the plans਍ഀ with the LSR continuing the wall to the roof sheathing. Provide detail for roof ventilation as wall to਍ഀ deck will eliminate ridge vent.਍ഀ ❑ LSR also states that they are utilizing section 705.7 of the 2003 IBC for combustible members਍ഀ entering the rated assembly at the party wall. The referenced section (705.7) is part of section 705਍ഀ "Fire Walls".

Amend plan to comply with Chapter 11. Provide all details, specifications, parking,਍ഀ accessible routes, etc. which would clearly show compliance with IBC for accessibility.਍ഀ As a result of the meeting held on 05102106 designer will determine feasibility of having਍ഀ all units comply with the Type B provisions on ANSI 117.1 1998 for accessibility.਍ഀ Refer BCER May 23, 2006 Memorandum of Understanding: Item #5, Pg. 4.਍ഀ Relative to `Type B' provisions, a Meeting was held Thursday 18 May 2006 with the਍ഀ appropriate Town of Vail and Front Door Design Team members to discuss the IBC਍ഀ Chapter 11 ICC/ANSI A117.1-1998 issue. It was decided that in order to obtain the਍ഀ `Grading & Excavation Permit' through this specific CIA Commentary (now dated਍ഀ May 2006), the Permit Applicant would describe the direction the Design am would਍ഀ be taking in complying with IBC Chapter 11. That description, as well as t e to਍ഀ used, is described below.਍ഀ m਍ഀ While many sections of IBC Chapter 11 were discussed, the consensus fo UQs one਍ഀ provisions of section 1107.6.3 `Group R-3' and 1107.7 `General exceptions' W o਍ഀ specifically 1107.7.2, 1107.7.3 and 1107.7.4. 3਍ഀ J਍ഀ Section 1107.7.2 `Multistory units' states that multistory units (dwelling or I~ ing)~਍ഀ without elevators are not required to have `Type B' units - but that if an ele gO is਍ഀ provided, and if that elevator provides access to only one level - then that ne eve਍ഀ shall "be accessible and contain a toilet facility". At the Chalets, elevator a cess coul਍ഀ only be achieved at the "lower levels" (generally the Junior Master Suite an u ti-਍ഀ Purpose levels) due to the Town of Vail Zoning height restrictions and other site਍ഀ impracticalities - requiring us to provide an intermediate landing between the top two਍ഀ levels (Kitchen/Dining and Living Room level at the top; Senior Master Suite level just਍ഀ below).਍ഀ Section 1107.7.3 `Elevator service to the lowest story with units' exempts access to the਍ഀ upper levels as long as access is provided to the lower levels serviced by an elevator.਍ഀ At the Chalets, as described above, the lower levels requiring access would be the਍ഀ Junior Master Suite and Multi-Purpose levels. In following the requirements of section਍ഀ 1107.7.2, an accessible toilet facility must be provided on those levels. It also must be਍ഀ noted that the IBC Commentary states that "if an elevator is utilized to provide access਍ഀ to only the lowest level containing dwelling or sleeping units, this building would not਍ഀ be considered an `elevator' building".਍ഀ Section 1107.7.4 `Site impracticality' describes under what conditions the required਍ഀ number of Type B units is permitted to be reduced - stating that "Type B units may be਍ഀ reduced to a percentage which is equal to the percentage of the entire site having਍ഀ grades, prior to development, which are less than 10 percent". At the Chalets, the਍ഀ entire pre-developed Chalet site is over 10 percent slope - though `Condition 1' states਍ഀ that no matter how steep the site, a minimum of 20 percent of the units would still need਍ഀ to be `accessible'. In that regard, of the 13 Chalet units, 2.6 units (13 x 20% [.20] = 2.6,਍ഀ rounding up to 3) would need to be `accessible' - 3 units that would then continue to਍ഀ comply with sections 1107.7.2 and 1107.7.3 as described above.਍ഀ In conclusion, 3 out of the 13 Chalet units will provide `access' as described above -਍ഀ including parking stalls and routes to those 3 units within the Residential parking਍ഀ garage (following ICC/ANSI All 17.1-1998 sections 1003.1 through 1003.11 - except਍ഀ z l਍ഀ 2਍ഀ LL,਍ഀ ar਍ഀ Cn U਍ഀ zZ਍ഀ W਍ഀ C.)
