CEQA
The California Environmental Quality Act (Pub. Res. Code § 21000 et seq.): discretionary approvals must analyze and mitigate significant environmental impacts.
Definition
The California Environmental Quality Act, Pub. Res. Code §§ 21000–21189.91, requires every California public agency to identify, disclose, and — where feasible — mitigate the significant environmental effects of projects it carries out or approves. It attaches to discretionary approvals (rezones, use permits, subdivision maps); purely ministerial approvals are outside it. The CEQA Guidelines implement the statute and supply the document hierarchy: exemption, negative declaration, mitigated negative declaration, or environmental impact report.
CEQA is enforced privately: any person may petition for a writ of mandate to unwind an approval, which is why it functions as litigation leverage as much as an analytical requirement.
Why it matters in an underwrite
For housing underwriting, CEQA is a schedule variable with a fat tail: an exemption resolves in weeks with a 35-day challenge window once a notice of exemption is filed, an MND adds months and is vulnerable to fair-argument challenges, and a contested EIR runs roughly 18–30 months before the litigation clock even starts. Which document a project draws — and whether the 2025 reforms (AB 130/SB 131) exempt it — often moves feasibility more than any fee or exaction.
