FAQ

New Construction ADU Questions

New construction ADU costs vary depending on size, finishes, and site conditions. Every project is unique, which is why we offer free consultations with detailed, no-obligation estimates that include design, permits, site prep, construction, and all finishes.
Under California law, detached ADUs can be up to 1,200 square feet regardless of lot size. Attached ADUs can be up to 50% of the existing home's floor area. Height limits are typically 16-25 feet depending on your city and whether the ADU is within 4 feet of a property line.
New construction ADUs typically take 8-14 months from design to completion. The design and permitting phase takes 2-4 months, followed by 6-10 months of construction depending on size and complexity.
Under AB 976 (effective 2024), California permanently eliminated owner-occupancy requirements for ADUs. You do not need to live on the property to build or rent out an ADU.
Under AB 1033 (effective 2025), California allows ADUs to be sold separately from the main home as condominiums, subject to local adoption. Check with your city for current status.
State law limits rear and side setbacks to 4 feet for detached ADUs. Front setbacks follow your local zoning code. No setback is required for conversion of existing structures.
Yes, California law (SB 897) now allows ADUs up to 18 feet in height, and up to 25 feet in some jurisdictions when near transit or in multi-family zones. Two-story ADUs maximize your living space while minimizing your yard footprint.
Vision ADU's turnkey service includes architectural design, structural engineering, Title 24 energy compliance, all city permits, site preparation, foundation, framing, electrical, plumbing, HVAC, insulation, drywall, flooring, cabinets, countertops, fixtures, paint, and final inspection coordination.
In most cases, no. California law eliminated parking requirements for ADUs located within half a mile of public transit, in historic districts, when part of an existing structure, or when on-street parking is available. Most properties in San Diego County qualify for parking exemptions.
Yes, you can add outdoor amenities near your ADU, subject to local setback and lot coverage rules. Many of our clients add a small patio, landscaping, or outdoor living area to increase the ADU's appeal and rental value.
