Full Breakdown

Violations & Fines
Building, enlarging or altering a residential pool without the required permit violates Section 12.20.030 and exposes the owner to the ordinance's general penalty under Section 12.53.010: a forfeiture of $10 to $500 per violation plus prosecution costs, with each day of noncompliance a separate offense and unpaid forfeitures defaulting to up to 30 days in the county jail. Starting construction before a permit is applied for and issued also triggers a triple permit fee under Section 12.05.090, which does not excuse the applicant from full compliance or from prosecution.
