14 23.10.104.14.7 Validity of permit. The issuance or granting of 15 a permit shall not be construed to be a permit for, or an approval 16 of, any violation of any of the provisions of this code or of any 17 other ordinance of the Municipality. Permits presuming to give 18 authority to violate or cancel the provisions of this code or other 19 ordinances of the Municipality shall not be valid. The issuance of 20 a permit based on construction documents and other data shall 21 not prevent the building official from requiring the correction of 22 errors in the construction documents and other data. The 23 building official is also authorized to prevent occupancy or use of 24 a structure in violation of this code or of any other ordinances of 25 the Municipality. 26 27 23.10.104.14.8 Expiration. Every permit issued by the building 28 official under the provisions of the technical codes shall expire 29 by limitation and become null and void, if the building or work 30 authorized by the permit is not commenced within 360 days from 31 the date of the permit issuance, or if the building or work 32 authorized by the permit is suspended or abandoned at any time 33 after the work is commenced for a period of 360 days. For the 34 purposes of this section, work shall be deemed suspended or 35 abandoned if no inspections have occurred within 360 days. If 36 the suspension or abandonment has not exceeded 18 months 37 the work may be recommenced upon application for 38 reactivation of the permit. For reactivation, the building official 39 shall have the option to either extend the previous plan approval 40 at no additional charge or, if a code change cycle has ensued in 41 the interim, require the applicant to revise the drawings 42 accordingly and pay a new plan review fee. For reactivation, the 43 permit fee shall be one of half the amount required for a new 44 permit for such work. In order to renew action on a permit 45 abandoned or suspended more than 18 months, the building 46 official may exercise the same option described above regarding 47 plan review, but the permittee shall pay a new full permit fee. 48 49 Exception: When it can be demonstrated that a substantial 50


amount of the previously permitted work has been inspected 1 and approved, the building official may allow the permit to be 2 reopened and final inspections to be conducted to close out the 3 permit. In these cases, the permittee shall pay an additional 4 amount for review of the project file and shall pay for any 5 allowed remaining required inspections on a per-inspection 6 basis. This exception will only be granted after review of the 7 permit history by the building official. The decision to grant this 8 exception is solely at the building official’s discretion. 9 10 A permittee holding an unexpired permit may apply for an 11 extension when the permittee is unable to commence work 12 within the time required by this section for good and satisfactory 13 reasons. The building official may extend the time for action by 14 the permittee for a period not exceeding 360 days upon written 15 request by the permittee showing circumstances beyond the 16 control of the permittee prevented action from being taken. 17 Permits shall not be extended more than one 360 day period, 18 unless otherwise approved by the building official. 19 20 Unless the property has a valid Conditional Use approved by the 21 Planning & Zoning Commission which sets a longer period of 22 time for completion, grading permits in residential zoned areas 23 shall be completed within two years of permit issuance. Once a 24 grading permit expires, a stop work order shall be issued, 25 investigative fees shall be paid to reactivate the permit, and a 26 bond posted. The bond shall be no less than the valuation to 27 complete the work. The bond shall be forfeited if work is not 28 completed within 180 days from the permit reactivation date. 29 30 23.10.104.14.9 Suspension or revocation. The building 31 official may, in writing, suspend or revoke a permit issued under 32 the provisions of this code and the technical codes when the 33 permit is issued in error or on the basis of incorrect information 34 supplied, or in violation of an ordinance or regulation or the 35 provisions of these codes. 36 37 23.10.104.14.10 Revising application (removing permittee). 38 In order to remove the permittee on a specific permit from 39 responsibility of completing the project and obtaining a 40 certificate of occupancy, the "Formal Transfer of 41 Responsibilities" form shall be completed and signed by the 42 Owner and permittee being removed. 43 44 23.10.104.14.11 Securing Suspended Work.

48 23.10.104.15 Fees. Fees shall be assessed in accordance with the 49 provisions of this section or shall be as set forth in the fee schedule 50


adopted by the Municipality. 1 2

23.10.104.15.1 Valuation. Valuation is determined as follows: 3 4

A. The valuation used to compute fees for new construction 5 shall be based on the Building Valuation Data Chart in 6 the most recent August issue of the Building Safety 7 Journal as published by the International Code Council. 8 The regional multiplier shall be 1.3. The rates in the 9 August issue shall become effective on the following 10 January 1st and continue to January 1st of the following 11 year. The valuation shall be calculated using the dollar 12 per square foot method. The area of the building shall be 13 the gross floor area; the total horizontal area of all floors 14 of a building, measured between exterior faces of exterior 15 walls, including interior balconies, mezzanines, stairwells, 16 elevator shafts, ventilation shafts, etc., but excluding area 17 without floor structure in atria. The area located under 18 canopies, eaves and overhangs extending more than 4 19 feet from the building perimeter shall be included in the 20 building area. The area under free-standing canopies 21 along with the occupancy classification, shall be used to 22 determine valuation. 23

24 B. The valuation used to compute fees for projects other 25

than new construction calculated under item 26 23.10.104.15.1 A. shall be provided by the permit 27 applicant and verified by the building official. The 28 valuation shall be the total cost required to complete the 29 project presuming all labor will be compensated and all 30 materials will be purchased at fair market value. Where 31 volunteer labor or donated materials are being 32 contributed, the valuation shall nevertheless include the 33 fair market value of donated labor and materials. The 34 building official reserves the right to require additional 35 documentation to verify valuation. 36

37 23.10.104.15.2 Plan review fees. 38 39 A. When documents are submitted in accordance with 40

subsection 23.10.104.10, plan review fees shall be paid 41 at the time of document submittal. Plan review fees shall 42 be calculated in accordance with Table 3-B. 43

44 Exception: A Fire Department Plan Review fee is not 45 required for detached one and two family dwellings. 46

47 B. Plan review fees are in addition to permit fees. 48 49 C. Where plans are incomplete or changed so as to require 50


additional plan review, an additional plan review fee shall 1 be charged at the rate shown in Tables 3-B of this code. 2

3 D. Structures that are identical to a previously approved and 4

permitted structure may qualify for "pre-approved" status 5 for purposes of the plan review fee assessment. The 6 plans must be submitted within the same code cycle. 7 Each identical structure shall be issued a separate 8 building permit. 9

10 E. Plan review fees for projects submitted under the 11

optional process described in section 23.10.104.9 qualify 12 for a reduced fee, as noted in Table 3-B. 13

14 23.10.104.15.3 Permit fees. Permit fees depend upon the type 15 and extent of construction. Some projects may be required to 16 pay for more than one type of permit fee, e.g., a building 17 containing an elevator will require a general building permit and 18 an elevator permit. The fee for each permit shall be as set forth 19 in Section 23.10 Tables 3-A through 3-N. Where a technical 20 code is adopted by the Municipality for which no fee schedule is 21 shown in this code, the fee required shall be in accordance with 22 the schedule established by the Assembly. Permit fees are 23 calculated as follows: 24

25 A. Permit fees for new construction are based on valuation 26

determined in accordance with 23.10.104.15.1(A). There 27 are no additional permit fees for plumbing, mechanical 28 and electrical permits. 29

30 B. Permit fees for additions, alterations and change of use 31

permits are not based on valuation. The fees are based 32 on an estimated number of inspections for all disciplines 33 provided by the permit applicant. The building official will 34 assist the permit applicant with the initial estimate. The 35 building official reserves the right to correct the estimate 36 based on historic information for similar projects. A 37 refund will be granted for inspections not used. Additional 38 fees are required for inspections exceeding the number 39 purchased. 40

41 23.10.104.15.4 Investigation fees and fines: 42 43

23.10.104.15.4.1 Investigation. Whenever work for 44 which a permit is required by this code is commenced 45 without first obtaining a permit, a code compliance 46 inspection for one or more disciplines may be required 47 before a permit is issued for such work. 48 49 23.10.104.15.4.2 Fee. When work is begun without 50


proper permits, an investigation fee at a rate shown in 1 Table 3-M, in addition to the permit fee, may be collected 2 whether or not a permit is then or subsequently issued. 3 The payment of the investigation fee shall not exempt an 4 applicant from compliance with all other provisions of this 5 code nor from the penalty prescribed by law. The building 6 official may waive the investigation fee for a first offense. 7 No individual or company granted a waiver under this 8 section shall be afforded additional waivers for future 9 offenses. When the building official has reasonable 10 cause to believe an inspection fee waiver is requested by 11 a person to avoid payment of the fee by another person 12 or company who was previously granted a first offense 13 fee waiver, the building official may deny the waiver 14 request. 15

The control or elimination of cross-connections shall 41 be in accordance with this code, the current edition of the cross-42 connection control manual published by the Pacific Northwest section of 43 The American Water Works Association and the manual of Cross-44 Connection Control published by the University of Southern California 45 Foundation for Cross-Connection Control. In the event a conflict exists 46 between the technical publications adopted herein and the Uniform 47 Plumbing Code, the most stringent provision shall apply. 48 49


UNSAFE FACILITIES: The Municipality of Anchorage may refuse to 1 furnish water and may discontinue services to any premises where 2 plumbing facilities, appliances, or equipment using water are dangerous, 3 unsafe, or not in conformity with the water utility tariff or other related 4 municipal ordinances. No potable water service connection to any 5 premises shall be installed or continued in use by a purveyor unless the 6 potable water supply is protected by all necessary backflow prevention 7 devices and assemblies. The installation or maintenance of a cross-8 connection, endangering the quality of the purveyor's water supply, shall 9 be unlawful and is prohibited. 10 11

ADMINISTRATIVE AUTHORITY: The Building Official or authorized 12 representative. 13 14 PURVEYOR: The operator or owner of a water supply. 15 16 PREMISES: Real property, including any house or building thereon, 17 located within the Municipality of Anchorage. 18 19 CROSS-CONNECTION INSPECTIONS: No water shall be delivered to 20 any structure hereafter built within the Municipality of Anchorage until it 21 is inspected by the Administrative Authority for possible cross-22 connections and approved as being protected from such cross-23 connections. 24 25 Inspections shall be made periodically of all potentially hazardous 26 buildings, structures, or improvements of any nature now receiving 27 water through the municipal water system, for the purpose of 28 ascertaining whether cross-connections exist. Such inspections shall 29 be made by the Administrative Authority. 30 31 Any building modification requiring a plumbing or mechanical permit 32 may require a cross-connection inspection and compliance. 33 34 POSSIBLE CROSS-CONNECTIONS: Backflow prevention assemblies 35 or devices shall be installed in any premises where, in the judgment of 36 the Administrative Authority, the nature and extent of activities, or the 37 materials used or stored on the premises, may present a hazard to the 38 potable water supply in the event a cross-connection were to be made; 39 even though such cross-connection has not been made. Such 40 circumstances include, but are not limited to: 41 42 1. Premises having an auxiliary water supply. 43 2. Premises having intricate plumbing arrangements making it 44

impractical to ascertain whether or not cross-connections in fact 45 exist. 46

3. Premises where entry is restricted so inspection for cross-connec-47 tions cannot be made with sufficient frequency or on sufficiently 48 short notice to assure cross-connections do not exist. 49


4. Premises having a repeated history of cross-connections being 1 established or re-established. 2

5. Premises on which any substance is handled under pressure, so 3 as to permit entry into the water supply. This shall include the 4 handling of process waters and cooling waters. 5

6. Premises where materials of a toxic or hazardous nature are 6 handled in such a way if back siphonage should occur, a health 7 hazard might result. 8

• 9 The following facilities, or portions of a building containing one of the 10 listed facilities, when connected to a potable water supply, require 11 backflow prevention assemblies or devices unless the authority with 12 jurisdiction determines no hazard exists. An example of a facility within a 13 building is a dental office in a multi-story office building. For this 14 application, a reduced pressure principle backflow preventer is required 15 to be installed on the hot and cold water serving the dental office and 16 backflow prevention is not required on the main supply to the building. 17 This protects both the city main and the occupants in the building: 18 19

Hospitals, mortuaries, and clinics; 20 Laboratories; 21 Metal plating industries; 22 Piers and docks; 23 Sewage treatment plants; 24 Food or beverage processing plants; 25 Chemical plants; 26 Petroleum processing or storage plants; 27 Radioactive material processing plants, nuclear reactors, or other 28 facilities where radioactive materials may be utilized; 29 Manufacturing facilities; 30 Car wash facilities; 31 Water systems not within the definition of potable water supply; 32 Fire sprinkler systems; 33 Medical/dental facilities; 34 Waterfront facilities; 35 Irrigation systems; 36 Laundries and dry cleaners; 37 High rise or other buildings above system pressure which require 38 booster pumps; and 39 Sand, gravel and concrete plants or other material processing 40 plants. 41

42 23.25.603.4 General requirements. 43 Amend by adding a second paragraph to section 603.4.1 as follows: 44 45
