Summary
Escondido charges an accessory dwelling unit permit fee set by city council resolution, plus a separate appeal fee if a director's decision is challenged. The city may also charge a proportionate utility connection fee when it requires a new water or sewer connection for the ADU, under Municipal Code § 33-1480.
§ 33-1480. Fees. (a) Upon the filing of a permit for an accessory dwelling unit, a fee in an amount to be established by resolution of the city council shall be paid by the applicant to the city. (b) Any party who appeals a determination made by the director of community development shall submit an appeal processing fee as determined by the city council. (c) The city may require a new or separate utility connection directly between the accessory dwelling unit and the utility. The connection may be subject to a connection fee or capacity charge that shall be proportionate to the burden of the proposed accessory dwelling unit, based upon either its size or the number of its plumbing fixtures, upon the water or sewer system.
Full Breakdown
Section 33-1480 of the Escondido Zoning Code sets the fee framework for accessory dwelling units in three parts. Subsection (a) requires the applicant to pay a permit fee upon filing an ADU application, with the amount set by resolution of the city council rather than fixed in the code itself. Subsection (b) adds a separate appeal processing fee, also set by council resolution, for any party who appeals a director of community development determination under the article's appeal procedure in § 33-1479. Subsection (c) addresses utility hookups: where the city requires a new or separate utility connection between the ADU and the water or sewer system, that connection can carry a connection fee or capacity charge, but the charge must be proportionate to the burden the ADU places on the system, measured by either the unit's size or its number of plumbing fixtures.
That utility fee is not automatic. 2(e)(1)(A), covering conversions within existing space; only ADUs that fall outside that carve-out, typically new detached construction, may be required to obtain a new connection and pay the associated fee.
Violations & Fines
Failing to pay the required ADU permit fee, appeal fee, or utility connection charge holds up the ministerial 60-day review clock and can result in an incomplete application being rejected rather than approved under § 33-1477. Occupying or renting an ADU built without the required permit, including unpaid fees, is treated as an unlawful use subject to code enforcement action under § 33-1476, backed by the general Municipal Code penalty in § 1-13: up to $1,000 in fines or six months in jail per violation.
