How much does an ADU cost in San Marcos?
Costs vary based on size, design, and site conditions. Generally, a detached ADU in San Marcos starts around $150,000, while garage conversions can be more cost-effective. We provide transparent, itemized estimates before any work begins so there are no surprises.
Do I need permits for a garage conversion in San Marcos?
Yes. The City of San Marcos requires building permits to ensure the conversion meets safety, zoning, and structural codes. Bernal Builders handles the entire permitting process on your behalf, ensuring your project is fully compliant and hassle-free.
What is the SB 721 inspection law in San Marcos?
SB 721 is a California state law requiring periodic safety inspections of exterior elevated elements, like balconies and decks, on multi-family buildings. Our team is fully qualified to perform these mandatory inspections in San Marcos, providing the necessary documentation and repair services if needed.
How long does a home remodel take in San Marcos?
The timeline depends heavily on the scope of work. A focused kitchen or bath remodel might take 4 to 8 weeks, while a full home renovation or ADU build can span 3 to 6 months. We pride ourselves on maintaining strict schedules and clear communication throughout the build.
How do I choose the right contractor in San Marcos?
Look for a licensed, insured, and locally experienced general contractor. Check their portfolio, read local reviews, and ensure they communicate clearly about timelines and costs. Bernal Builders has deep roots in San Diego County and a reputation for quality craftsmanship and reliability.
