1. State Building Code.

1. Part 2, Title 24, C.A.C. Sec. 2-5351(b) l is amended as enacted by the county to read as follows: "Water heating budgets. The budgets for water heating systems for each building type and climate zone shall be those specified in Table 2-53Y. The annual water heating budgets specified in Table 2-53Y may be met by installing any gas storage type non-recirculating water heating system that does not exceed 50 gallons of capacity and that meets the minimum standards for efficiency and standby losses specified in Section 2-5314 and the requirements of Section 2- 5352(i) or by the installation of an Electric Plus domestic water heating system as specified by resolution of the Board of Supervisors of the County of Del Norte. Calculate the energy consumption of all other water heating systems using an approved calculation method."

2. Part 2. Title 24, C.A.C., item 8 is amended as enacted by the county to read as follows: "Water Heating Systems. All water heating systems must meet the water heating budgets specified in Table 2-53Y, or be installed in compliance as specified by resolution of the Board of Supervisors of the County of Del Norte. Solar domestic water heating systems installed to meet the requirements of Alternative Component Package C in Tables 2-53Z1 through 2-53Z16 shall be designed so that the total system's use of depletable resources does not exceed 40 percent of the energy budget in Table 2-53Y, calculated using an approved calculation method."

3. The definition of "substandard building" set forth in California Health and Safety Code Section 17920.3 shall be used in place of the definition of "substandard building" from the Uniform Housing Code.

2. Local Building Code.

1. Footing Design. In order to reduce structural damage due to soil movement of expansive soils from fluctuations of soil moisture and to minimize seismic damage, all residential footings shall be structurally designed, including slab-on-grade footings, to include, at a minimum, the following steel reinforcement:

   1. For foundations supporting one floor there shall be two #4 (one-half-inch) rebar placed within the footing itself The placement of the rebar in the stemwall shall be such that a "continuous" bar of the same diameter rebar is formed.

   2. For foundations supporting two floors there shall be two #5 (five-eighths-inch) rebar placed within the footing itself. The placement of the rebar in the stemwall shall be such that a "continuous" bar of the same diameter rebar is formed.

   3. If more than one pour of concrete is used in the construction of the foundation footing and stemwall, #4 rebar placed vertically at four feet on center is required.

2. Under Floor Moisture Barrier. Due to excessive soil moisture conditions in Del Norte County, an impervious moisture barrier shall be placed between the excavated grade and the floor area. This provision applies to both structurally supported floors and to slab-on-grade concrete floors. Where the area below the lowest supporting member to the average grade exceeds three feet, the placement of a moisture barrier is optional.

3. Under-Floor Clearance. In order to enhance protection against decay and termite infestation the following shall apply:

   1. Where the sub-floor rests directly on a girder and no floor joists are used the girder shall be no less than eighteen inches above grade.

   2. Concrete poured as a pest barrier under a structurally supported floor is to be considered as part of the measurement above grade, however there shall be a minimum clearance of twelve inches between the lowest supporting member and the poured in place concrete.

4. Ventilation. Due to the high humidity prevalent within Del Norte County the following measures are intended to prevent moisture build-up and condensation:

   1. A minimum of two inches of clearance shall be maintained between the insulation placed in the "attic" area and the inside of the roof. Such clearance shall be constructed in such a manner as to provide continuous air flow and shall apply to all types of ceiling/roof construction including shed roofs, cathedral ceilings, and other ceiling construction.

   2. A non-permeable material may not be used as a vapor barrier in the construction of the exterior walls or ceiling of any residential construction, unless specifically designed by a California licensed engineer or architect and specifically designed to re flect the local climatic conditions of Del Norte Coun ty for the climatic region in which the building is located.

   3. The ration of under-floor ventilation to the area of the under-floor space shall not be less than one square foot for each one hundred square feet of under floor area. The ration of attic ventilation to the area of the attic space shall not be less than one square foot for each one hundred square feet of attic area and/or space ventilated.

5. Support Systems. In order that the appropriate service connections and installations are properly sized and de signed, all support systems applicable to residential development may only be installed as part of the building permit issued for the subject residential construction or placement.

6. Meter Bases.

   1. All single-family residential construction, or placement of a manufactured home, within all single-family "R" zone districts are permitted to have one electrical meter base per legally established parcel as part of the issuance of the building permit establishing the residential use of the parcel. Exceptions are permitted for legally established pre-existing nonconforming uses, use permits issued by the planning commission for home enterprises that meet County Code requirements for a second electrical meter for commercial purposes, for second single-family dwellings with individual utilities in compliance with County Code that have been issued a building permit.

   2. All new meter bases, including the replacement of an existing meter base, are to be designed to provide for future underground service where overhead service is currently provided. Where underground service is provided, the meter base shall be designed for underground service.

7. Metal Connectors.

   1. Seismic and Hurricane Anchors. Metal connectors designed to provide wind and seismic ties for trusses and rafters may be used for anchoring purposes, however such metal connectors shall be designed for the specific purpose and shall be installed on the outside of the plate member.

   2. Roof Truss Blocking/Clips. Placement of the lower chord of a truss or frame on the top plate of a non bearing wall shall require blocking or the installation of a roof truss clip to provide alignment control between the roof truss and the nonbearing wall.

8. Roof Overhangs. Pursuant to Government Code Section 65852.5, roof overhangs are required on conventional single-family residential construction as specified in Sec tion 20.48.130 of Del Norte County Code.

9. Pole Structures. All pole structure (pole barns) over one thousand square feet in floor area are required to have engineered plans submitted with the building permit application. Such plans shall be prepared by an engineer licensed and registered to practice in California.

10. Slab Flooring. Concrete or other slab flooring construction, within the conditioned floor area, shall, as a minimum, contain No. 3 rebar spaced four feet zero inches on center in each direction or 6-6-10-10 concrete reinforcement wire.

11. Placement of Manufactured Homes. Manufactured homes, which for the purposes of this code include mobilehomes, trailers, and all other prefabricated dwelling units, are separate residential units, the construction and alteration of which are regulated by the state of California. No manufactured home shall be stored or placed in such a manner as to be physically connected or adjoined to any other residential unit, nor shall any manufactured home be modified so as to permit its physical connection or adjournment to any other residential unit. Nothing contained herein shall prevent the lawful placement of manufactured homes on parcels of land which are approved mobilehome parks or are approved for other multifamily uses, or otherwise approved for manufactured home use.

12. Property Lines. Any applicant proposing to set a structure within twenty-five feet of a property line or easement or right-of-way functioning as a property/lot line, shall identify the affected property line, easement or right-of-way line in the field. Such identification shall include marking in the field the subject property line(s) sufficient to permit the building inspector to verify building setbacks. The accuracy of the property line identification is the responsibility of the applicant.

(Ord. 90-14 § 3, 1990)

As provided in Section 17958.2 of the California Health and Safety Code, the county finds that the application of Article 10 of Subchapter 1 of Chapter 1 of Title 25 of the California Administrative Code is reasonably necessary because of local conditions to the following areas(s):

Sunstar Area (the east half of the SE quarter of Section 34 and the south half of the SW quarter of Section 35 in R19NR5E): This rural area of the county is surrounded in total by federal ownership, is not provided with nor anticipated to be serviced by commercial electrical service, and is designated and zoned for low-density rural uses. A use permit (No. 1871) has been issued specifying the maximum allowable density and conditions of compliance.

(Ord. 85-15 § 1, 1985)

1. All residential and commercial buildings shall have approved address numbers conspicuously posted at all times. Address numbers shall be posted on the side of the building facing the frontage street.

2. In the event address numbers are not visible from the frontage street, the approved address numbers shall be placed at the beginning of the driveway. If more than one driveway services a single structure the approved numbers shall be placed at the beginning of each driveway. Where there are more than one residential or commercial buildings with separate addresses located on the same driveway, or driveways, the approved address numbers shall be placed upon both the structure and at the beginning of the driveway.

3. All buildings shall be issued an address by the local jurisdiction which conforms to that jurisdiction's overall address system. Accessory buildings will not be required to have a separate address; however, each dwelling unit within a building shall be separately identified.

4. No certificate of completion nor certificate of occupancy nor a mobilehome installation permit shall be issued unless the address of the building is displayed in conformance with Section 14.16.027 (posting of addresses) and Section 14.16.028 (Approved address numbers) of this Code.

(Ord. 2016-003)

The size of letters, numbers and symbols for address signs shall be a minimum 4-inch letter, 1/2-inch stroke, reflectorized, white to contrast with the background green reflectorized color of the metal sign.
