Milpitas, California homeowners and developers must navigate city rules on accessory dwelling units (ADUs), multiunit energy standards and lead abatement when altering residential buildings.

ADU rules overview

The City of Milpitas adopts state ADU requirements and local development standards that affect lot coverage, setbacks, parking and utility connections; see the Municipal Code for zoning and development standards and the Planning & Building department for permit procedures Municipal Code[1] and Planning & Building[2].

Apply early for a building permit to avoid retroactive enforcement.

Multiunit energy requirements

Energy upgrades and new construction in multiunit buildings are governed by California’s Title 24 energy code as applied through Milpitas building permit review; local permits ensure compliance with insulation, HVAC, lighting, and efficiency measures during permit intake via the Building Division. For projects that change occupancy or add units, plan-check will confirm applicable energy measures during permit review and inspections.

Lead abatement and disclosure

Renovation, repair and painting affecting pre-1978 housing may trigger federal and state lead-safe work practices and disclosure duties; Milpitas enforces safe construction practices through its Building Division during permit review and inspections, and may coordinate with county public health for abatement in certain cases.
