What are California's ADU rules in 2024-2025?
California law allows ADUs up to 1,200 sq ft on most single-family lots, with reduced setbacks (4 ft side/rear), no parking requirements near transit, and streamlined permitting (60-day approval timeline). San Diego County and cities have additional local rules. We stay current on regulations to maximize your options.
Can I convert my garage to an ADU?
Garage conversions are one of the most cost-effective ADU options. California law protects garage conversions from parking replacement requirements in most cases. Key considerations include ceiling height (must reach 7'6"), foundation adequacy, and utility access. We assess feasibility during our initial consultation.
How long does ADU construction take?
Plan for 8-14 months total: 2-4 months for design and permits, 4-8 months for construction. Garage conversions are faster (4-6 months construction). Detached new construction takes longer (6-10 months). Permit timelines vary by jurisdiction — Carlsbad and Encinitas typically process faster than unincorporated areas.
What's the ROI on building an ADU in San Diego?
ADUs in North County San Diego typically rent for $1,800-$3,500/month depending on size and location. A $200,000 ADU renting for $2,500/month generates $30,000/year in gross income. Many homeowners see 12-18% annual returns. ADUs also add 20-30% to property resale value.
