Enter the size of each ADU you need designed (under 1200 SF). The fee uses your sliding price tiers; additional ADUs on the same property are discounted as you add units.
What’s included
Two-phase process: concept planning, then permit documentation — building design, general MEP layouts, Title 24, and structural coordination
Custom building design with five rounds of revisions, then a coordinated permit drawing package for your jurisdiction. Drafting and design documentation—this is not licensed architecture.
ADU design & permit set includes:
PDF, CAD/DWG, and high-resolution exports included. Typical turnaround 4–8 weeks depending on scope.
- Five rounds of design revisions (custom building design included).
- Phase 1 — Concept planning: study-level layouts, elevations, and design direction before detailed permit drawings.
- Phase 2 — Permit documentation: complete permit-ready drawing package (building plans and sheets coordinated for submittal).
- General MEP layouts (not engineering calcs) sufficient for typical ADU submittals.
- Title 24 / energy compliance documentation is included.
- Structural engineering is included in this pricing.
- Lighting & electrical design plan (does not include electrical load calculations).
- 3D massing views to help you visualize the ADU volume and form.
- PDF, CAD/DWG, and high-resolution image exports of your permit set.
- Typical turnaround between 4–8 weeks, depending on scope and city review timing.
How it works
A simple, clear process from concept to approval. We handle the design and permit documentation; you stay oriented at every milestone.
Design analysis & options
We review your goals and site constraints, then develop design directions and layouts that respect code context and how you want to live in the space.
Permit set development
We produce a coordinated, permit-ready documentation package for your jurisdiction—architectural sheets plus general MEP layouts, Title 24 / energy documentation, and structural coordination as scoped.
City comments until approval
We coordinate responses and revisions through plan review so comments are addressed systematically—not left for you to interpret alone.
This is for you if…
- You value thoughtful, well-analyzed design over rushed production work
- You want a cohesive process from design analysis through permit coordination
- You understand that quality design requires collaboration and clear communication
- You are looking for a tailored solution instead of generic drafting services
- You want guidance navigating layouts, constraints, and city requirements
- You appreciate detail, aesthetics, and buildability equally
- You are ready to invest in a process designed around long-term value, not just speed

Frequently asked questions
Straight answers about permit documentation, coordination, and how we work with homeowners.
Do you provide permit-ready plans?
Yes. Depending on the project scope, we provide permit-ready architectural and MEP documentation packages, including Title 24 / energy compliance documentation, with structural engineering included or excluded based on your calculator selection.
How does payment work?
ADU permit set fees use two payment milestones on your calculator total: 60% retainer to start the project, and 40% prior to permit submittal (invoiced when you reach that phase—you’ll receive a payment request on your dashboard or by email). The project is marked complete only when the city approves the permit, not when the final payment is received.
Can I stop the project early (termination)?
Termination: Work may be stopped at any time at your request; however, payment is due for work completed at the time of stoppage, together with reimbursable expenses then due and all terminal expenses resulting from such stoppage. See Terms & Conditions (Section 15).
Do you offer structural engineering?
Yes, when you leave the calculator checkbox unchecked. Structural engineering is then included in the fee and coordinated through licensed professionals. If you check “Show pricing without structural engineering included,” structural is not in the fee and your chosen engineer provides calculations, details, and stamps.
Do you work remotely?
Yes. Arch Design by B is a remote studio. We work online only—video calls, email, and shared files. We do not meet on site or travel to the property as part of the design fee. An on-site visit happens only if we are explicitly hired for that, and you cover travel and related expenses.
Can you help with city comments and revisions?
Yes. We coordinate responses and revisions throughout the review process until the permit phase is completed.
Do you take every project?
No. We prioritize projects that align with our workflow, communication style, and design approach. A free 15-minute fit call is the easiest way to find out if we’re a match.
What is the free 15-minute fit call?
A complimentary conversation (no design work) to discuss your ADU, lot, timeline, and whether we’re a good fit. Pick a weekday time below—no payment required. We’ll email your meeting details.
What information do I need before starting?
Property address, site information (if available), inspiration images, goals for the project, and any existing plans or surveys you may have.
Can I start with design analysis before committing to a full permit set?
Yes. Many clients begin with a preliminary design analysis to explore layouts, feasibility, and overall direction before moving into permit documentation.
Do you provide construction services?
No. We focus on design and permit documentation. Clients may work with their preferred contractor or builder.
How long does the process take?
Every project is different. Timelines depend on project complexity, responsiveness, revisions, consultant coordination, and city review durations.
