Background: 
 
1. 
August 26, 1996: A deed (1996-0599146) is recorded for what will become APN 504-12-004A, 
which will soon be split from its parent parcel, APN 504-12-004. 
 
2. 
c. 1996 – 1997: APN 504-12-004 is formally split into five child parcels, per Split Control ID 96719. 
 
3. 
December 29, 2009: The current owners of the subject parcel take possession of its parent parcel, 
APN 504-12-004A, per Deed 2009-1189898. 
 
4. 
June 26, 2023: A new deed is recorded for each of what will become the five child parcels of APN 
504-12-004A. These include (from south to north) parcels 504-12-237, -238, -239, -240, and -241. 
 
5. 
September 22, 2023: APN 504-12-004A is formally split into five child parcels. The southernmost 
of these, APN 504-12-237, is the subject of this variance request. However, all five of the current 
child parcels created by the unregulated land division are of substandard lot width and area. 
 
6. 
January 3, 2025: The owner submits the subject variance request.

Variance Requests: 
 
8. 
The property owner, Sonia Prieto, is requesting variances to the development standards of the 
Maricopa County Zoning Ordinance (MCZO) to permit a lot area of 43,552 square feet and a lot 
width of 132’ on Parcel 504-12-237, where 43,560 square feet and 145’, respectively, are the 
minimums required in the Rural-43 zoning district.

Site Analysis: 
 
9. 
The subject parcel was created following a series of unregulated land divisions. Prior to 1996, the 
site formed a portion of a much larger parcel corresponding with the southwest quarter of the 
southeast quarter of Section 7, Township 1 North, Range 5 West. This parent parcel, APN 504-12-
004, measured approximately 40 acres with each side measuring approximately a quarter mile. 
In 1996 or 1997, an unregulated land division was recorded from which five child parcels were 
established, including APN 504-12-004A, which itself corresponded with the north half of the west 
half of the west half of its parent parcel’s legal description. 
 
10. 
Several subsequent lot splits recorded in the following years have resulted in what are now as 
many as 26 child parcels of the original parent. Included among these 26 are five parcels which 
were split from APN 504-12-004A in 2023. Each of these five parcels measures approximately 
one acre in area and approximately 132’ in width, as documented in the record of survey attached 
to this report. When taking the precise measurements documented in the record of survey, each 
of the five parcels is slightly substandard in area, measuring slightly under one acre, but only by 
a matter of eight to 14 square feet. With a surveyed area of 43,552 square feet, or 0.9998 acres, 
the subject parcel is the closest of the five to one acre (43,560 square feet). The most significant 
consequence of this lot split, however, is that each of the five parcels now measures a surveyed 
width of 132.03’, nearly 13’ shy of the minimum required in the Rural-43 zoning district.

11. 
As a result of the unregulated land division, each of the five child parcels of APN 504-12-004A is 
nonconforming to the Rural-43 lot width and lot area regulations. The ideal remedy would be to 
combine the parcels again, resulting in a width of 660.15’ along the west lot line (the only lot line 
with street frontage). If desired, the property could then be split into a maximum of four parcels 
measuring no less than 145’ in width. If the four parcels were to be approximately equal in width 
and area, each would measure a width of 165.04’ and an area of approximately 1.25 acres, 
meeting the Rural-43 zoning district’s minimum width and area requirements. 
 
12. 
Complicating this remedy, however, is that the middle of the five child parcels has since been sold 
to a new owner (ownership of the remaining four, including the subject site, remains the same as 
of the writing of this report). Combining the northernmost two parcels and the southernmost two 
parcels would negate the need for variance on the land subject to this request, but one parcel 
would remain nonconforming. Besides obtaining variances, the only alternative would be for the 
new owner of the middle parcel to purchase additional land corresponding with a total width of 
at least 145’ along 351st Avenue; subsequent lot split/combinations could result in two, three, or 
four parcels within the survey area all conforming to the Rural-43 width and area regulations.

13. 
The subject parcel itself does not appear to possess any conditions which may be considered 
peculiar. Typical for most Rural-43 properties, the subject parcel is rectangular in shape, gentle in 
slope, and not encumbered by hillside or areas of floodplain. There is a nearby wash that bisects 
some of the lot split parcels to the north, but it does not encumber the subject parcel. The west 
lot line forms the centerline of the easement for 351st Avenue. Although this easement measures 
a half-width of 20’, it is also aligned along a mid-section line, so preservation of 40’ on either side 
of the centerline is required unless otherwise waived or reduced by MCDOT. As such, the required 
40’ front yard setback must be measured in addition to the 40’ of preservation for a de facto front 
setback measuring 80’ from the west lot line. 
 
14. 
Site aerials show a shade structure (possibly a mare motel) straddling the lot line shared between 
the subject parcel and its northern neighbor. This structure predates the land division and appears 
to have been built as an accessory structure to the manufactured home that is now on the middle 
parcel. If the parcels are all to remain as currently recorded, this structure will need to be removed 
or otherwise relocated and properly permitted so that it remains within the confines of a single 
parcel and meets setback requirements. 
 
15. 
Staff notes that, if the requested variances are granted for the subject parcel, the four parcels to 
the north will remain nonconforming. If those parcels are to remain as currently recorded, it will 
be incumbent upon their respective owners to request variances for each. One variance 
application would be required for each parcel, with each application requesting two variances: 
one for lot area and one for lot width. Again, an alternative remedy would be to combine the 
parcels so that each measures a width of no less than 145’ and an area of no less than 43,560 
square feet.

State Statute / County Zoning Ordinance Tests - ARS § 11-816.B.2 and MCZO Article 303.2.2 states the 
Board of Adjustment may, “Allow a variance from the terms of the ordinance if, owing to peculiar 
conditions, a strict interpretation would work an unnecessary hardship and if in granting the variance the 
general intent and purposes of the zoning ordinance will be preserved.”  
 
17. 
Statutory Test 1 – Does the applicant’s property contain any peculiar condition – Discuss and 
explain the peculiar conditions facing the property and include reference to the Maricopa County 
Zoning Ordinance Regulations or Development Standards to be varied.   
 
“This lot is 43,552 sq.ft. shy of an acre (43,560). We need a variance on the lot width so we can 
build a new home on this lot. If we do not get a variance we can’t build a new home. This lot was 
subdivided by original lot APN 504-12-004A. We told the Surveyor we wanted 5 acre lots. It was 
done by Survey Arizona Allen Sadberry. He gave us map and it said 1 acre on each lot 504-12-237, 
504-12-238, 504-12-239, 504-12-240, 504-12-241 so we did the deeds. We went to planning and 
zoning to let them know we would like to build a home and they said we couldn’t the lots where not 
one acre (43,560). They said we can do a lot split again and cutting a bit on lot 504-12-239 to get 2 
one acre lots to the south and north. By this time we had already sold 504-12-239 with the 
manufactured home so that was not no longer an option. If we would of looked at the sq.ft. of each 
acre since the beginning before doing the deeds but the surveyor didn’t tell us they were not a full 
acre we could of take care of it right there and then and would of note sold lot 504-12-239.” 
 
18. 
Statutory Test 2 – Does applying the requirements of the Ordinance to the applicant’s property 
create an Unnecessary Hardship – Explain how the peculiar condition identified in #1 causes an  
unnecessary hardship to the property when the requirements of the Maricopa County Zoning 
Ordinance are applied.  Explain how the peculiar condition of the property came to be and whether 
the condition was created by the applicant or someone in the property’s line of title. Explain the 
proposed use of the property with the variance request. Identify and explain all peculiar conditions 
on your property in regard to the following areas: slope, narrowness, shallowness, irregular shape, 
location, washes, vegetation, and easements, etc. Explain how enforcement of the Zoning 
Regulations or Development Standards would impose a hardship on the property.

Page 7 of 8 
 
“The surveyor divided the lot and shows 1 acre and its only 43,552 sq.ft. not 43,560. Because of the 
Surveyor mistake it created all this mess. We already spent lots of money on all this. We have also 
have a well guy that is suppose to do a well for the lots.” 
 
19. 
Statutory Test 3 – General Intent and Purpose of the Zoning Ordinance – Discuss the purpose 
of the zoning requirement from which the variance is being sought. Then, discuss and explain 
how, provided statutory tests #1 and #2 are satisfied, the granting of the requested variance 
would preserve the general intent and purpose of the Zoning Ordinance. 
 
“If we get a variance accepted on this property it won’t affect the surrounding area. We have seen 
lots with a lot less than acre with a new built home.” 
 
Findings:  
 
20. 
The applicant has the burden of proving to the Board that, in accordance with the standard set 
forth in ARS §11-816.B.2 and MCZO Article 303.2.2, the property requires a variance. To grant the 
relief, the applicant must prove, and the Board must find and identify, a physical condition of the 
applicant’s property that is peculiar and not common to the area or the universe of the zoning 
district. Also, any such peculiarity must not have been created either by the applicant or anyone 
in the chain of title. If the Board determines that there is no such peculiar physical condition, its 
inquiry stops, and the application must be denied. 
 
If the Board identifies a peculiar physical condition of the applicant’s property which is not self-
imposed, then the applicant must prove, and the Board must find and identify, an unnecessary 
hardship imposed upon the property due to the strict application of the requirements of the zoning 
ordinance which the applicant wishes to have varied such that there is no viable use of the 
property without the variance.  
 
If the Board identifies a peculiar physical condition of the property which is not self-imposed, and 
that in applying the requirements of the zoning ordinance to the property, because of the peculiar 
physical condition, an unnecessary hardship exists, the applicant must prove, and the Board must 
find and identify, how the granting of the variance will preserve the general intent and purpose of 
the zoning ordinance. 
 
In order to approve the variance, the Board must make findings and articulate them in motion 
memorializing the above.   
 
21. 
Based upon what the applicant has submitted and the staff analysis in this report, staff offers the 
following positive and/or negative observations the Board may consider in its findings: 
 
• 
Staff is unable to identify a peculiar condition facing the property. Typical for most Rural-
43 properties, the subject parcel is rectangular in shape, gentle in slope, and not 
encumbered by hillside or areas of floodplain. 
 
• 
Staff is unable to identify an undue hardship created by the enforcement of the MCZO. 
The substandard lot area and lot width were created in the direct line of title because of 
poor lot-splitting practice with unregulated land divisions.  The substandard lots were 
avoidable. The need for variance could have been avoided had more care been taken in 
the splitting of the parent parcel (or if the parcel had not been split at all). One option 
available to the owner would be to combine the subject parcel with the adjacent parcel to 
the north.

• 
The granting of the requested variance, the need for which could have been avoided, would 
fail to preserve the general intent and purpose of the MCZO. 
 
22. 
And further, if the Board finds the applicant has satisfied the statutory test, and has stated its 
findings on the record, the grant of this variance will memorialize the following: 
 
a) 
Variance approval establishes a 43,552-square-foot lot area for APN 504-12-237. 
 
b) 
Variance approval establishes a 132-foot lot width for APN 504-12-237
