Full Breakdown
Section 9-3.2650, item 4, of the Huntington Park Municipal Code sets the impact fee treatment of accessory dwelling units, as part of Article 26 adopted by Ordinance 2025-13 and effective January 23, 2026. The exemption has two thresholds: ADUs less than 750 square feet of interior livable space, and JADUs less than 500 square feet of interior livable space, are not subject to impact fees. An ADU that is 750 square feet of interior livable space or larger is charged proportionately, using the printed formula of the square footage of the ADU divided by the square footage of the primary dwelling unit, multiplied by the Amount of Fee.
The article prints no dollar figures, so the fee amount itself comes from whatever impact fee applies to the primary dwelling. Primary dwellings are subject to the full amount of all applicable impact fees, and the ADU relief never reduces the primary dwelling's charge. Utility charges are handled in item 9 of the same section. If a detached ADU is constructed with a new single-family home, a separate utility connection directly between the ADU and the utility is required, with payment of the normal connection fee and capacity charge for a new dwelling.
Converted ADUs on a single-family lot are not required to have a new or separate utility connection, and no connection fee or capacity charge is required. ADUs can otherwise share utility services and meters with the primary dwelling. The permit itself is a minor development permit under § 9-3.2630, processed as a ministerial action. Because § 9-3.2620 sends any standard not enumerated in the article to the California Government Code, a fee question that Article 26 does not answer is resolved under State law.
Violations & Fines
Article 26 prints no penalty for fee issues. A person who willfully violates the Code or a permit issued under it is liable under § 9-2.2407(1)(D) for a civil penalty in compliance with the City's Schedule of Fees for each day the violation continues, and also owes the City its costs and damages. Administrative decisions can be appealed in writing to the Council through the City Clerk (§ 1-4.01).
