A lot confirmation is an administrative review that verifies one or more lots, lot remnants, adjusted lots or lots of record, or combination thereof, have legal status as a property that is eligible for development under the zoning code. A lot confirmation is often undertaken to confirm lots or lots of record that have previously been combined for tax purposes.
The review also ensures that existing development remains in conformance or does not move further out of conformance with Title 33 development standards, and that all previous land use conditions of approval are met. Lot confirmations may be combined with a Property Line Adjustment to re-establish a historic lot line then move it.

Lot confirmation standards
Zoning Code Section 33.676.300
A Lot Confirmation must address the following standards:
- Lot or lot of record - Each lot or lot of record that will be confirmed meets the definition of lot, adjusted lot, lot remnant or lot of record. Find lot related definitions in Chapter 33.910, Definitions.
- Minimum lot dimension standards – The following lot dimensions standards must be met without necessitating a Property Line Adjustment:
- In the OS, C, EX, CI and IR zones, each lot must have a front lot line that is at least 10 feet long. There are no other minimum lot dimension standards.
- In the single-dwelling zones, each lot must have frontage on a street, and each lot must meet the standards of 33.110.202, When Primary Structures are Allowed.
- In the multi-dwelling zones, each lot must have frontage on a street, and each lot must meet the standards of Section 33.120.205, Development on Lots and Lots of Record.
- In the EG zones, each lot must meet Standard B stated in Table 614-1.
- In the I zones, each lot must meet Standard B stated in Table 615-1.
- If the lot is in an overlay zone or plan district that regulates minimum lot dimensions, the minimum lot dimension standards of the overlay zone or plan district must be met instead of the standard that corresponds to the base zone.
- Development standards - Existing development must remain in conformance or not move further out of conformance with the development standards of the Zoning Code. An adjustment to the development standards in question or a Property Line Adjustment can be requested to ensure that the site does not move out of conformance with development standards.
- Conditions of previous land use reviews – All applicable conditions of previous land use reviews must be met.
Lot confirmation review process
Lot confirmations are reviewed through an administrative procedure that generally takes between six to eight weeks to complete. The Water Bureau and Bureau of Environmental Services review Lot Confirmations for impacts on water, sanitary sewer and stormwater management services, but only make informational comments about potential future development issues.
A Lot Confirmation approval must be submitted to the appropriate county assessment and taxation office within 90 days of the City’s decision. The County is responsible for creating separate tax identification numbers for each confirmed lot.
