Section § 1917.150

Explanation

If you make significant improvements to your property, you can add their value to the overall property value for certain financial calculations, like future interest. To do this, you must notify your lender within 60 days after finishing upgrades that cost over $2,500. If the lender questions the new value, you both can agree on a value or get appraisals. You'll split the appraisal costs, and any increase over $2,500 can be credited. If you did at least half the work yourself, the cost doesn't have to be over $2,500 for this process.

The borrower may have the value of capital improvements added to the borrower’s cost of the property, for purposes of determining net appreciated value and the amount of contingent deferred interest, but only if the procedures set forth in this article are followed.
(a)CA Civil Law Code § 1917.150(a) Within 60 days following the completion of capital improvements during any 12-month period with a cost in excess of two thousand five hundred dollars ($2,500), the borrower shall send by first-class mail a notice of the completion of the improvements to the lender and shall submit proof of cost and an estimate of the increase in value of the property by reason of the improvements.
(b)CA Civil Law Code § 1917.150(b) If, within 30 days of receipt of the notice, the lender questions the claimed increase in value of the property by reason of the improvements, the lender and the borrower may, by mutual agreement, establish the value of the capital improvements or the lender may require appraisal of the property. An appraisal shall be made to determine the increase in value of the property, if any, by reason of the improvements, by two appraisers selected in the same manner specified in Section 1917.142. If appraisals are performed, the increase in value resulting from the improvements for the purposes of this section, shall be one-half of the sum of the two appraisals. The cost of the appraiser selected by the borrower shall be borne by the borrower, and the cost of the appraiser selected by the lender shall be borne by the lender.
(c)CA Civil Law Code § 1917.150(c) A credit for the value of capital improvements shall be provided if the increase in value of the property resulting therefrom is determined pursuant to subdivision (b) to exceed two thousand five hundred dollars ($2,500).
(d)CA Civil Law Code § 1917.150(d) If 50 percent or more of the value of the labor or other work on the improvements was performed by the borrower, then the actual cost of the improvements need not exceed two thousand five hundred dollars ($2,500) for purposes of making application under subdivision (a).

Section § 1917.151

Explanation
This section allows a shared appreciation loan to offer borrowers a larger credit for home improvements than what's usually stated, as long as the required disclosures are updated to show these terms clearly.
Nothing in this article shall preclude a shared appreciation loan from providing the borrower with a greater credit for improvements than specified in this article, provided the relevant disclosures required by Article 7 (commencing with Section 1917.170) are appropriately modified to accurately disclose the terms of the credit.
