"The Uniform Building Code and Title 19 do not necessarily meet the minimum requirements of the ADA or the FHA. The City and Borough of Juneau does not enforce those federal laws. Compliance with this code does not constitute compliance with the federal laws and does not provide immunity from liability under the federal laws." "Under section 19.01.104.2.7 and section 19.01.104.2.8, Modifications and Alternative Materials and Methods, the City and Borough review plans prepared under the federal laws and approve construction work performed under the federal laws as meeting this code without thereby certifying that any federal requirements have been met.

Group R, Division 3 occupancies are houses with one or two units as well as zero-lot line homes and zero-lot townhouses. C. Type A dwelling units are required to be fully accessible for the disabled.
D. Type B dwelling units are "adaptable", roughly meaning that room and door dimensions are adequate and fixture controls are mounted for use by disabled individuals but grab bars do not need to be installed and cabinets and fixtures can be installed at standard heights as long as they can be easily adjusted for use by disabled individuals. E. Adaptable (Type B) units are only required on the ground floor unless an elevator is installed and the building code does not require elevators in any residential building. (UBC 1103.1.9.3, Exception 1) F. Individual units that extend up more than one story in height and do not have elevators do not require adaptability. (UBC 1103.1.9.3, Exception 3) G. The number of units requiring adaptability may be reduced by the percentage of the site with original grades in excess of 10 percent. (UBC 1103.1.9.3, Exception 4) The UBC requirement for adaptable dwelling units in four-unit and larger projects is based on the Federal Fair Housing Amendments Act of 1988 and is required by federal law regardless of whether federal funds are involved. The Federal Fair Housing Amendments Act is enforced by lawsuit in federal court similar to the Americans with Disabilities Act. 19.03.1103.1.10 Building accessibility, Group S occupancies. In UBC Section 1103.1.10, Building accessibility, Group S occupancies, add the following exception: "Exception: For the total number of accessible for-rental storage units, use the same number of units as the number of required parking spaces in Table A-11-A, Number of Accessible Parking Spaces, in UBC Appendix Chapter 11.

"3) Seasonal structures: Toilet facilities may be as per (2) above. The seasonal building itself shall be wheelchair accessible per the ICC/ANSI A117.1 or ADA-AG guidelines if more than the owner(s) will be allowed in the building." "Exception: Access is always required for kiosks used by the public. For employee-only kiosks, a "broker" kiosk requires a five-foot turning diameter due to potentially more than one person working inside; "vendor" or one-person working kiosks can delete the fivefoot circle as long as the door is wide enough for a wheelchair and the employee can back into the vendor kiosk and work from within. Also, when only employees use these vendor kiosks (never the public), then ICC/ANSI A117.1 or ADA-AG complying entrance platforms and ramps are not required; rather, a portable ramp stored on-site is an acceptable alternate." "4) First phase buildings: Toilet facilities may be as per (2) above. The first phase building itself shall be wheelchair accessible per the ICC/ANSI A117.1 or ADA-AG guidelines." "5) Temporary fabric covered buildings: Access for the disabled is required when building permits are required by title 19 for uses which require access for persons with disabilities. Access is required per (2) or (3) above when more than the owners enter or occupy the building." "6) Caretaker facilities: no accessibility requirements." 19.03.1105.2.2 Facility accessibility, toilet facilities.

No allowance for natural ventilation by openable windows is allowed. The system shall deliver not less than the air volume of outside or return air or both as required by this code." In the second paragraph, delete the following: "... a fully openable exterior window with an area not less that three square feet (0.279 m 2 ), or... "
