"Fire official" means the chief of the fire protection district in which the building site is located, or for locations not within such a district, the county fire marshal.
"Merger" means the joining of two or more contiguous parcels or units of improved or unimproved land, which are held by the same owner or owners, into one building site pursuant to this chapter. Parcels or units may include land division or subdivision lots or portions thereof, assessor's tax parcels, or lots or portions thereof created by deed.
"Merger by operation of law" means the merger of parcels by or through the law without direct action by the county or property owner. As used in this chapter, "merged by operation of law" refers to the merger of parcels pursuant to the provisions of the State Subdivision Map Act and the Napa County Code in effect prior to January 1, 1984.
"Minimum parcel size" means the minimum size to permit development under established zoning, subdivision or other county codes.
"Same Owner." Contiguous parcels or units of land may be considered to be held by the same owner where any of the following apply:
The persons or entities designated as the grantees on the respective deeds or other conveyances are identical or would be identical except for spelling inconsistencies, the substitution of an initial for a portion of a name, the inadvertent deletion of a first, middle, or last name, or the use of a name not the legal name of the grantee at the time of the conveyance;
The same individuals or entities would have qualified as the same owner under subsection (A) at one point in time, but at some later point in time a transfer of one of the parcels or units of land was made without consideration; provided, however, that gifts to blood, step or adoptive relatives of the grantor, or charitable institutions, which were reported as gifts pursuant to state and federal taxation laws shall not be considered as transfers made without consideration;
The same individuals or entities would have qualified as the same owner under subsection (A), but at some later point in time a transfer of a fractional interest in one or more of the parcels or units of land occurred for the purpose of circumventing the merger statutes; or
Subsections (1) through (3) do not apply but based on existing facts and circumstances it is reasonable to conclude the parcels are under the same ownership.
Unless it is clear the motivation for the change in ownership was for the purpose of circumventing the merger statutes or this chapter, "Same Owner" shall not include the following:
a. One parcel or unit of land is held by an individual and a contiguous parcel or unit of land proposed for merger is held by a corporation or partnership even if said individual has a financial interest in the corporation or partnership;
b. One parcel or unit of land is held by a spouse as separate property and both spouses hold as community property a contiguous parcel or unit of land proposed for merger;
c. One parcel or unit of land is held by an irrevocable trust and any contiguous parcel proposed for merger is held by a separate irrevocable trust, an individual, a corporation or a partnership;
d. The fee title of the contiguous parcels or units of land are held by the same owner but recorded deeds of trust, mortgages or the like involving the parcel or unit of land are held by separate financial institutions; or
e. Subsections (1) through (4) do not apply but based on existing facts and circumstances it is reasonable to conclude the parcels are not under the same ownership.

Were not subject to provisions of the Subdivision Map Act or the county code, or any prior ordinances regulating the division of land, if any, at the time of their creation.
B. If such creation has occurred, no further proceeding under the provisions of this title shall be required to permit the sale, lease or financing of such contiguous parcels or units of land; provided, however, that all such legal parcels may be merged in accordance with the provisions of this chapter.
(Ord. 854 § 2 (part), 1987: prior code § 11695.20)
17.48.040 - Merger conditions and specifications.¶
A. On or after January 1, 1984, two or more contiguous parcels or units of land held by the same owner or owners shall be subject to merger if any one of the contiguous parcels or units of land does not conform to the standards for minimum parcel size of the zoning district in which the parcels or units of land are located, and if all of the following requirements are satisfied:
At least one of the affected parcels or units of land is undeveloped by any structure for which a building permit was issued or for which a building permit was not required at the time of construction, or is developed only with an accessory structure or accessory structures, or is developed with a single structure, other than an accessory structure, that is also partially sited on a contiguous parcel or unit of land; and

i. If an approved water supply system does not exist on an affected parcel or unit of land on the date the notice of intention to determine status is recorded, it shall be presumed the parcel does not meet current standards for domestic water supply.
ii. Notwithstanding the immediately preceding subsection, if affected parcels or units of land are served by an existing individual water supply system that is not an approved water supply system on the date the notice of intention to determine status is recorded, it shall be presumed the parcel does not meet current standards for domestic water supply unless both the minimum sustained yield, and the minimum storage capacity standards, contained in Sections 13.04.060 and 13.04.090, were met on the date the notice of intention to determine status was recorded.
iii.

d. The affected parcel or unit of land has slope stability or other geologic hazards as shown on the Napa County Environmental Sensitivity Maps which cannot be mitigated to an acceptable degree for development.

e. As of the date the notice of intention to determine status is recorded the affected parcel or unit of land has no legal access which is adequate for vehicular and safety equipment access and maneuverability.

It shall be presumed that a parcel with the required sixty feet of frontage has legal access which is adequate for vehicular and safety equipment access and maneuverability, unless evidence is presented at the hearing by the director of planning, a fire official, or their designees that, despite sixty feet of frontage, it is not possible for either a standard passenger vehicle or safety equipment to enter the property from any designated roadway;
f. Development of the affected parcel or unit of land would create health or safety hazards;

b. The proposed creation of one of the affected parcels or units of land proposed to be merged was authorized by the county subsequent to December 29, 1955, as a result of the approval of a tentative parcel or subdivision map, but that approval also included a finding to the effect that the purpose of the approval was to accomplish the transfer of property but was not intended to result in the creation of any new parcel, and the parcel or unit of land so approved was thereafter created by parcel map or deed; or
c. The parcel or unit of land was created in violation of applicable laws and ordinances in effect at the time of its creation.
