Planning commission backs ADU ordinance updates to align with state law; notes sewer, fire and landscaping issues

The Fillmore Planning Commission voted 5-0 to recommend that the City Council adopt Zoning Ordinance Amendment No. 25-984, updating the city's accessory dwelling unit (ADU) rules to align with current state law and to adopt a CEQA exemption for those changes. Planning staff presented the amendment and said the update references current state code sections and clarifies multiple ADU rules. Why it matters: the ordinance clarifies sizes and definitions, removes an owner-occupancy requirement for ADUs (while retaining it for junior ADUs), and specifies when ADU construction does not trigger retrofitting requirements such as fire sprinklers. Those changes affect how many ADUs can be built, what permits are needed and how the city enforces standards. Key changes described by planning staff include updated references to applicable California code sections; clarified maximum size for attached ADUs; new language for nonconforming conditions related to health and safety; a provision addressing utility undergrounding (noting Southern California Edison lines); revised height allowances; elimination of an owner-occupancy requirement for ADUs while preserving it for junior ADUs; limits on junior ADU expansion to ingress/egress; allowance for detached ADUs in existing multifamily developments up to the number of existing units (capped at eight); a statement that adding an ADU to an existing single-family dwelling will not require retroactive installation of fire sprinklers; and updated definitions (including 'livable space' and tandem parking). Commissioners pressed staff on enforcement and public-safety details. On sewer capacity, planning staff said ADU construction is restricted in parts of North Fillmore because a trunk sewer pipeline on B and C streets is at capacity; the Creekside development by Williams Homes is expected to construct pipeline improvements that would relieve the restriction in that subarea. Staff said any change to allow more ADUs there would follow a sewer-capacity study and confirmation that the line can accept additional load. On enforcement, staff explained that deed restrictions and recorded notices will be required where the ordinance mandates owner-occupancy periods or other restrictions, but enforcement is largely complaint-driven; code enforcement would investigate complaints such as short-term rental turnover or other violations and pursue action if needed. Staff estimated the administrative fee for ADU plan check at about $300, with building permit fees typically adding several hundred dollars and generally staying under $1,000. On fire safety, staff said planning entitlements establish the right to build but that construction drawings must comply with the California Building Code and the fire code, which govern smoke detectors, alarms and other systems. The commission discussed the city's recent adoption of the state's Very High Fire Hazard Severity Zone map, new building-code updates expected in late 2025, and the role of the fire chief in site-by-site plan checks. Commissioners asked whether additional hydrants or other water-supply upgrades could be required; staff said the fire department regularly tests hydrants and may require applicant-provided upgrades where a specific project creates a new demand. Commissioners also discussed landscaping standards. Staff said the ordinance currently requires ADUs to match the primary unit's architectural materials and generally expects disturbed areas to be restored and landscaped, but the city has not adopted objective, quantified landscape standards for ADUs; commissioners asked staff to draft a concise, objective landscaping clause for the council hearing. Planning staff warned that the California Department of Housing and Community Development (HCD) will review the ordinance after local adoption and may require changes if provisions conflict with state law. The motion recommending the council adopt the ordinance (and asking the council to consider added objective landscape language) passed 5-0. Staff will forward the recommendation to City Council and continue coordination with HCD and the fire department.
