All Department of Building Safety fees which contain a fraction of a dollar will be rounded to the next highest dollar.

108.3 Building permit valuations. Add the following sentence:

The applicant for a permit shall provide an estimated value of all the work to be performed including mechanical, electrical, and plumbing at time of application. Final building permit valuation shall be as determined by the building official.

108.4 Investigation Fee. Any person who commences any work on a building, structure, electrical, gas, mechanical or plumbing system before obtaining the necessary permits, or is in violation of the approved plans, shall be subject to an investigation fee. The investigation fee shall be in addition to the required permit fee, shall be equal to the permit fee, and shall be collected whether or not a permit is then or subsequently issued.

108.4.2 Reinspection fees. A reinspection fee may be assessed for each inspection or reinspection when such portion of work for which inspection is called is not complete or when corrections called for are not made.

Reinspection fees may be assessed when the inspection record card is not posted or otherwise available on the work site, the approved plans are not readily available to the inspector, for failure to provide access on the date for which inspection is requested, or for deviating from plans requiring the approval of the building official. A re-inspection fee may be assessed for failure to post a readily visible address.

To obtain a reinspection, the applicant shall pay the reinspection fee in accordance with Table 1-A. In instances where reinspection fees have been assessed, no additional inspection of the work shall be performed until the required fees have been paid

108.5.1 Plan review fee. When submittal documents are required by Section 106.1, a plan review fee shall be charged on all permits. This fee may be required at time of

submittal of the documents for plan review. Said plan review fee shall be 65 percent of the building permit fee as shown in Table 1-A.

The plan review fees specified in this Section are separate fees from the permit fees specified in Section 108.2 and are in addition to the permit fees.

When submittal documents are incomplete or changed so as to require additional plan review or when the project involves deferred submittal items as defined in Section 106.3.4.2, an additional plan review fee shall be charged at the rate shown in Table 1-A.

108.5.2 Expiration of plan review. Applications for which no permit is issued within sixty (60) days following the date of application shall expire by limitation and plans submitted for checking may thereafter be returned to the applicant or destroyed by the building official.

In order to renew action on an application after expiration, the applicant shall resubmit plans and plan review fee. Said plan review fee shall be 65% of the building permit fee as shown in Table 1-A.

108.6 Fee refunds. Add the following:

The building official may authorize the refunding of any fee paid hereunder which was erroneously paid or collected. The building official may authorize the refunding of not more than 50% of the permit fee paid when no work has been done under a permit issued in accordance with this Code.

108.6.1 Processing fee. There will be a minimum $30.00 fee for processing refunds.

108.6.2 Plan review fee refunds. The building official may authorize the refunding of the plan review fee paid when an application for a permit for which a plan review fee has been paid is withdrawn or cancelled before any plan reviewing is done.

108.6.3 Fee refund application. The building official shall not authorize the refunding of any fee paid except upon written application filed by the original permittee not later than sixty (60) days after the date of the fee payment.

108.7 Reinspections fees. A reinspection fee may be assessed for each inspection or reinspection when such portion of work for which inspection is called is not complete or when corrections called for are not made.

This Section is not to be interpreted as requiring reinspection fees the first time a job is rejected for failure to comply with the requirements of this Code, but as controlling the practice of calling for inspections before the job is ready for such inspection or reinspection.

To obtain a reinspection, the applicant shall pay the reinspection fee in accordance with Table 1-A or as set forth in the fee schedule adopted by the jurisdiction.

In instances where reinspection fees have been assessed, no additional inspection of the work will be performed until the required fees have been paid.

Wildfire Zone Map

See Map

The Wildfire Zone line generally follows what is called the "mountain front," which is a line connecting the average Eastern-most points on the 6400 foot contour line of the U.S.G.S. topographic maps. The State Forest Service concurs that this line indicates the predominant change from plain to mountain topography. The canyons are within the Wildfire Zone 1 because of the chimney-effect of the terrain. The location of the Wildfire Zone Line recognizes vegetation, slope, fire department accessibility, water supply, response time and infrastructure.

This line has been imposed on the Jefferson County Base Map to divide the County into two Wildfire Zones as described in Chapter 15 of the Jefferson County Supplement to the International Building Code.

The Wildfire Zones shall include such territory or portions of the unincorporated county as shown in Figure No. 1, the Wildfire Zone Map, which is attached to and incorporated into this chapter by this reference and is located in this Supplement. For sites close to the dividing line, a larger scale map is available in the Planning and Zoning Department for determining within which Wildfire Zone a property is located.

1505.9 Buildings located in more than one Wildfire Zone. A building or structure which is located partly in one Wildfire Zone and partly in another shall be considered to be in the Wildfire Zone in which more than one-third of its total floor area is located.

1505.10 Moved buildings. Any building or structure moved within or into any Wildfire Zone shall be made to comply with all the requirements for new buildings in that Wildfire Zone.

1505.11 Restrictions in Wildfire Zone 1.

Except where Section 1505 and Table 1505.1 require greater protection, roof coverings for new buildings or structures or additions thereto or roof coverings utilized for re-roofing shall be Class A in accordance with Section 1505.2. Re-roofing includes any repairs of more than 10% of the total roof covering during any three-year period. A repair of 10% or less of the total roof covering in any three-year period may utilize approved roofing materials comparable to the existing roofing materials.
