Report of Independent Registered Public Accounting Firm

The Administrative Committee, as Plan Administrator
of the KB Home 401(k) Savings Plan

We have audited the accompanying statements of net assets available for benefits of the KB Home 401(k) Savings Plan as of December 31, 2004 and 2003, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Plan’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan at December 31, 2004 and 2003, and the changes in its net assets available for benefits for the years then ended, in conformity with U.S. generally accepted accounting principles.

Our audits were performed for the purpose of forming an opinion on the financial statements taken as a whole. The accompanying supplemental schedule of assets (held at end of year) as of December 31, 2004, is presented for purposes of additional analysis and is not a required part of the financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in our audits of the financial statements and, in our opinion, is fairly stated in all material respects in relation to the financial statements taken as a whole.

1. General Description of the Plan

The KB Home 401(k) Savings Plan (the “Plan”), formerly the Kaufman and Broad Home Corporation Amended and Restated 401(k) Savings Plan, is a defined contribution plan in which salaried employees of KB Home (the “Company”) are eligible to participate on the first day of the month following their date of hire.

Participants electing to participate in the Plan may contribute up to 15% of their annual compensation, on a pretax basis, by means of payroll deduction. Participants may also contribute up to an additional 15% of their annual compensation, on an after-tax basis, also by means of payroll deduction. All contribution rates must be designated in whole percentages. Pretax contributions are eligible for tax deferred treatment up to the limits provided by the Tax Reform Act of 1986, as adjusted for cost of living.

Effective August 1, 2003, each Participant whose designated rate of employee deferral contribution as of a payroll period is at least 6%, who has attained (or will attain) age 50 before the close of the Plan year and whose employee deferral contributions for the plan year will exceed the limits of Internal Revenue Code (the “Code”) Section 402(s) or other Plan limit is eligible to make a catch-up contribution in accordance with, and subject to the limitations of, Code Section 414(v) as an additional employee deferral contribution.

Unless otherwise elected by the Company’s Board of Directors, the Company will match the participant’s pretax contribution up to 6% of annual base salary (determined without regard to bonuses and a maximum of $50,000 of regular earnings for commission employees). Company matching contributions and related investment income vest to participants over five years.

Plan assets are held by Fidelity Management Trust Company, Inc. (the “Trustee”). Plan participants may direct the investment of their funds among one or more of the several fund options offered by the Plan.

Terminating participants may elect to withdraw their contributions, vested Company contributions and related investment income as a lump-sum payment. In the absence of a valid election, the participant’s vested benefits will be distributed in the form of a Qualified Joint and Survivor Annuity or a Qualified Preretirement Survivor Annuity, or in a lump sum if the actuarial equivalent is not more than $5,000.

1. General Description of the Plan (continued)

Nonvested Company contributions for terminated employees are forfeited and used by the Company to reduce future employer contributions. For the years ended December 31, 2004 and 2003, the Company used $717,977 and $725,233, respectively, of forfeitures to reduce employer contributions. The forfeiture balances available to offset future employer contributions were $451,127 and $14,193 at December 31, 2004 and 2003, respectively.

The Plan allows participant loans and hardship withdrawals subject to certain limitations.

In the event of Plan termination, benefits of all affected participants, if not already so, shall become 100% vested and nonforfeitable.

On February 14, 2003, the assets of American Heritage Homes 401(k) Plan were transferred into the Plan in conjunction with the Company’s acquisition of American Heritage Homes. On February 17, 2004, the assets of the Colony Homes, LLC Employee Savings and Profit Sharing Plan were transferred into the Plan in conjunction with the Company’s acquisition of Colony Homes, LLC. On November 1, 2004, the assets of the Dura-Builders, Inc. 401(k) Profit Sharing Plan and Trust were transferred into the Plan in conjunction with the acquisition of Dura-Builders, Inc.

2. Summary of Significant Accounting Policies

The financial statements of the Plan are prepared on an accrual basis. Investment income is recorded as earned. Distributions of Plan benefits to withdrawn participants are recorded when distributed. Expenses incurred in the administration of the Plan are paid by the Company.

The financial statements are based on information provided to the Company and certified as complete and accurate by the Trustee. Certain adjustments have been made to the financial statements provided by the Trustee in order for them to conform to the accrual basis of accounting. The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that could affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

3. Investments

Investments are valued at fair value, which is determined daily by the Trustee through reference to published market information using closing prices on the valuation date for mutual funds and common stock and based on closing balances for cash and participant loans.

4. Tax Status of the Plan

The Plan has received a determination letter from the Internal Revenue Service dated February 28, 2002, stating that the Plan is qualified, in form, under Code Section 401(a) and, therefore, the related trust is exempt from taxation. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan is qualified and the related trust is tax exempt.
