ADU FAQs
How much does it cost to get ADU plans?
Costs depend on your property conditions and the complexity of the ADU (garage conversion vs. new two-story detached unit, for example). After a brief feasibility call and reviewing your parcel, we’ll provide a written proposal for design and drafting services.
Can you work with my contractor or builder?
Yes. Many clients come to us before they hire a contractor, but we’re also happy to coordinate with your existing team.
Do you submit to the city for me?
We can prepare a permit-ready drawing set and, if requested, assist with the application process and responses to city comments related to our scope.
What cities are you familiar with?
We regularly work with Pasadena, City of Los Angeles (LADBS), and surrounding jurisdictions across the San Gabriel Valley and LA area.
What’s the first step?
Start with a quick ADU Feasibility Call. We’ll talk through your goals, property, and budget level so you can decide if an ADU makes sense before you invest in full drawings.
