In addition to the requirement that a local agency allow the separate sale or conveyance of an accessory dwelling unit pursuant to Section 66341, a local agency may also adopt a local ordinance to allow the separate conveyance of the primary dwelling unit and accessory dwelling unit or units as condominiums. Any such ordinance shall include all of the following requirements:

Before recordation of the condominium plan, a safety inspection of the accessory dwelling unit shall be conducted as evidenced either through a certificate of occupancy from the local agency or a housing quality standards report from a building inspector certified by the United States Department of Housing and Urban Development.

(A)

A lienholder may refuse to give consent.

(B)

A lienholder may consent provided that any terms and conditions required by the lienholder are satisfied.

(2)

Prior to recordation of the initial or any subsequent modifications to the condominium plan, written evidence of the lienholder’s consent shall be provided to the county recorder along with a signed statement from each lienholder that states as follows:
“(Name of lienholder) hereby consents to the recording of this condominium plan in their sole and absolute discretion and the borrower has or will satisfy any additional terms and conditions the lienholder may have.”

(3)

The lienholder’s consent shall be included on the condominium plan or a separate form attached to the condominium plan that includes the following information:

(A)

The lienholder’s signature.

(e)

The local agency shall include the following notice to consumers on any accessory dwelling or junior accessory dwelling unit submittal checklist or public information issued describing requirements and permitting for accessory dwelling units, including as standard condition of any accessory dwelling unit building permit or condominium plan approval:
“NOTICE: If you are considering establishing your primary dwelling unit and accessory dwelling unit as a condominium, please ensure that your building permitting agency allows this practice. If you decide to establish your primary dwelling unit and accessory dwelling unit as a condominium, your condominium plan or any future modifications to the condominium plan must be recorded with the County Recorder. Prior to recordation or modification of your subdivision map and condominium plan, any lienholder with a lien on your title must provide a form of written consent either on the condominium plan, or on the lienholder’s consent form attached to the condominium plan, with text that clearly states that the lender approves recordation of the condominium plan and that you have satisfied their terms and conditions, if any.
In order to secure lender consent, you may be required to follow additional lender requirements, which may include, but are not limited to, one or more of the following:

(a)

Paying off your current lender.
You may pay off your mortgage and any liens through a refinance or a new loan. Be aware that refinancing or using a new loan may result in changes to your interest rate or tax basis. Also, be aware that any subsequent modification to your subdivision map or condominium plan must also be consented to by your lender, which consent may be denied.

(b)

Securing your lender’s approval of a modification to their loan collateral due to the change of your current property legal description into one or more condominium parcels.

(c)

Securing your lender’s consent to the details of any construction loan or ground lease.
This may include a copy of the improvement contract entered in good faith with a licensed contractor, evidence that the record owner or ground lessee has the funds to complete the work, and a signed statement made by the record owner or ground lessor that the information in the consent above is true and correct.”

(f)

If an accessory dwelling unit is established as a condominium, the local government shall require the homeowner to notify providers of utilities, including water, sewer, gas, and electricity, of the condominium creation and separate conveyance.

(g)

(1)The owner of a property or a separate interest within an existing planned development that has an existing association, as defined in Section 4080 of the Civil Code, shall not record a condominium plan to create a common interest development under Section 4100 of the Civil Code without the express written authorization by the existing association.

(2)

For purposes of this subdivision, written authorization by the existing association means approval by the board at a duly noticed board meeting, as defined in Section 4090 of the Civil Code, and if needed pursuant to the existing association’s governing documents, membership approval of the existing association.

(h)

An accessory dwelling unit shall be sold or otherwise conveyed separate from the primary residence only under the conditions outlined in this paragraph or pursuant to this article.
