Welcome to the PAS Architects Fee Estimator — a set of self-guided tools designed to help you understand the cost of architectural services across common project types. Unlike generic architecture cost calculators, each estimator here reflects our actual pricing structure for design services in California. Whether you’re building a custom home, adding an ADU, remodeling an existing space, or planning a commercial improvement, these tools offer fast, transparent insight into your potential design fees — no sign-up, no sales pitch, just real information for better planning.
Our custom home estimator provides a quick way to calculate design fees based on your project size, location, and site conditions. If you’re planning a new build on a private lot, hillside, or suburban infill site, this tool offers real-time pricing drawn from our residential design experience across California.

| Question | Answer |
|---|---|
| Do these tools reflect actual PAS Architects pricing? | Yes. Each estimator reflects real California architect fees based on how PAS Architects scopes and prices work — not generic national averages. |
| Which estimator should I use for my project? | Use the tool that fits your project: Custom Home, ADU/JADU, or Remodel. For commercial or tenant improvements, use the consultation option. |
| Is this an architecture cost calculator or something more? | This is more than a generic architecture cost calculator. These tools use our actual fee structure to provide real planning estimates based on scope, location, and service type. |
| How accurate are the results? | Our architectural fee estimator tools are typically accurate within ±15% of final proposal pricing. They’re ideal for planning and budgeting before a formal proposal. |
| Do these estimates include permitting and documentation? | Yes. All estimates assume full permit-ready drawings, consultant coordination, and city plan check support. Learn more in our architectural design process. |
| What if my project doesn’t fit into these categories? | If your project is mixed-use, commercial, or something more complex, request a free consultation. We’ll provide a tailored proposal based on your goals. |
