Do you handle permits for home additions and remodels?
Yes—100%. We manage all permitting, engineering, and HOA approvals for home additions, garage conversions, and remodels in San Antonio and Bexar County. We pull all required permits, schedule inspections, and ensure your project is fully code-compliant from start to finish.
How long does a typical home remodel take?
Timelines vary by project scope:
- Kitchen remodel: 6–10 weeks
- Bathroom remodel: 3–5 weeks
- Whole-home renovation: 3–6 months
We provide a detailed timeline during your consultation and keep you updated throughout construction.
What's the difference between a garage conversion and an ADU?
A garage conversion transforms your existing attached or detached garage into livable space (like a home office or gym). An Accessory Dwelling Unit (ADU) is a fully contained living unit with a kitchen, bathroom, and sleeping area—perfect for rental income or multi-generational living. We specialize in both!
