Essential Homeowner Questions
1. Can I build an ADU on my property?
Most residential properties in California are legally permitted for ADUs under state legislation (SB 9/AB 68). We perform a complimentary lot survey to verify setbacks, easements, and utility tie-in requirements.
2. How long does the permitting process take?
Permit review times vary by city (e.g. LADBS, LA County, Pasadena, Glendale), typically taking 6 to 14 weeks. Our in-house expediting team manages plan check reviews directly to avoid unnecessary delays.
3. Does H&A handle both design and permits?
Yes, 100%. We are a true turnkey design-build general contractor. We handle architectural CAD design, structural engineering calculations, Title 24 energy packets, and all city permit submittals.
4. How is construction pricing determined?
We don’t provide misleading square-foot menu prices. After surveying your lot and utility runs (sewer, electrical panel capacity, gas/water), we provide a fixed-scope proposal detailing materials, labor, and milestones.
5. How long does construction typically take?
