How much does a room addition cost in San Diego?
Room additions in North County San Diego typically cost $300-$500 per square foot. A 200 sq ft bedroom addition runs $60,000-$100,000. A 400 sq ft primary suite with bathroom averages $150,000-$250,000. Garage conversions are more affordable at $150-$300 per sq ft since the shell exists.
Can I convert my garage without replacing the parking?
California state law (AB 2299) eliminated parking replacement requirements for garage conversions in many situations, especially near transit. Local rules vary — Carlsbad, Encinitas, and San Marcos have different requirements. We research your specific property during feasibility assessment.
Do room additions require permits in San Diego?
Yes — room additions require building permits in all San Diego jurisdictions. The process includes plan review, foundation/framing inspections, and final approval. Permit timelines run 4-12 weeks depending on the city. We handle permit coordination as part of our service.
How long does a room addition take to build?
Most room additions take 3-6 months from permit approval to completion. Simple conversions (garage to office) might be 6-10 weeks. Complex additions with new foundation and roofing run 4-6 months. We provide realistic timelines during the estimate process.
Will a room addition match my existing home?
Matching your home's architecture is a priority. We source matching or complementary materials for roofing, siding, and trim. Interior finishes blend with existing flooring and paint. The goal is an addition that looks original, not tacked-on.
What's the best ROI for room additions?
Bathroom additions typically return 50-60% of cost at resale. Primary suite additions return 50-65%. Sunrooms and bonus rooms return 40-50%. Beyond ROI, additions provide daily value through improved functionality. We help evaluate options based on your goals.
