| Adjustment To PEO Compensation, Footnote [Text Block] | | | | (1) Eric Lipar was the CEO and Principal Executive Officer for 2022, 2021, and 2020. The summary compensation totals for Mr. Lipar are adjusted, as indicated in the table below, to arrive at the compensation actually paid to the CEO each year. The change in value to the RSUs is due to the decrease in stock price from the date the RSUs were granted to the date the RSUs vested or will vest. The value change to the PSUs is due to the decrease in stock price from the date the PSUs were granted to the date the PSUs vested or will vest and the decrease of the payout percentage of the PSUs.

The average summary compensation table totals for Non-CEO NEOs are adjusted, as indicated in the table below, to arrive at the average compensation actually paid to the Non-CEO NEOs each year using the same methodology as described for the CEO.

The value change to the PSUs is due to the decrease in stock price from the date the PSUs were granted to the date the PSUs vested or will vest and the decrease of the payout percentage of the PSUs.

| Compensation Actually Paid vs. Total Shareholder Return [Text Block] | | | | Relationship Between Compensation Actually Paid and Cumulative TSR As demonstrated by the following graph, the amount of compensation actually paid to the CEO and the average amount of compensation actually paid to the Non-CEO NEOs have generally aligned with the Company’s cumulative TSR over the three-year period presented in the table. With respect to equity awards, the terms of the PSUs provide that the payouts will be capped at 100% of the target number of PSUs granted if absolute TSR is negative during the performance period, regardless of Basic EPS performance. See “What We Paid and Why - Compensation for NEOs - 2022 LTI Program - PSUs” for more information. |
| Compensation Actually Paid vs. Net Income [Text Block] | | | | Relationship Between Compensation Actually Paid and Net Income As demonstrated by the following graph, the amount of compensation actually paid to the CEO and the average amount of compensation actually paid to the Non-CEO NEOs have generally aligned with the Company’s net income over the three-year period presented in the table. While the Company does not use net income as a stand-alone performance measure in the overall executive compensation program, the measure of net income is correlated with the measure pre-tax net income (which is net income before income taxes). As further discussed in the section that follows, the determination as to the amount of the total Annual Bonus payment earned by each participating NEO under the Annual Bonus Plan is significantly influenced by the pre-tax net income generated for the year as compared to target. |
| Compensation Actually Paid vs. Company Selected Measure [Text Block] | | | | Relationship Between Compensation Actually Paid and Pre-Tax Net Income As demonstrated by the following graph, the amount of compensation actually paid to the CEO and the average amount of compensation actually paid to the Non-CEO NEOs has generally aligned with the Company’s pre-tax net income over the three-year period presented in the table. While the Company uses TSR, earnings per share, home closings and pre-tax net income for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that pre-tax net income over the long-term is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation actually paid to the NEOs to Company performance. The Compensation Committee’s determination as to the amount of the total Annual Bonus payment earned by each participating NEO under the Annual Bonus Plan is significantly influenced by the pre-tax net income generated for the year as compared to target. For 2022, 2021 and 2020, the total Annual Bonus payment to be earned by each participating NEO was based (i) 75% on the pre-tax net income during the year as compared to target and (ii) 25% on the number of home closings during the year as compared to the target. The payouts could range from 0% - 200% of the target annual bonus amount depending on the results achieved as compared to the threshold, target, and maximum for each measure, calculated and awarded independently, such that one portion of the award may be earned even if the threshold level of performance for the other measure is not achieved. The performance targets and payout terms applied to each NEO based on the Compensation Committee’s determination that each is integral to the overall success of the Company. See “What We Paid and Why - Compensation for NEOs - Annual Cash Bonus - Short-term Incentive Compensation” for more information. |
| Total Shareholder Return Vs Peer Group [Text Block] | Relationship Between Cumulative TSR of the Company and Cumulative TSR of the Peer Group As demonstrated by the following graph, the Company’s cumulative TSR over the three-year period presented in the table was $131.07, while the cumulative TSR of the peer group presented for this purpose, the S&P Select Industry Index, over the three-year period presented in the table was $132.08. | | | |
