If you’re planning a home addition, ADU, garage conversion, new construction, or any residential project the first thing the city needs is a complete set of permit drawings. Not just floor plans. A full, code-compliant permit set that the building department can review, approve, and stamp. At Fast-Build, we’ve prepared residential permit drawings for over 150 projects across California and other U.S. states from single-family homes and ADUs to multi-unit buildings and new construction. Our primary base is California, where we have deep experience with local jurisdictions and building departments. We also work with clients in other states who need a reliable team to handle their permit drawing process from start to finish.
Residential permit drawings are a set of technical documents submitted to the city before construction begins. Their purpose is to show the building department that your project meets local building codes, zoning requirements, and safety standards.
Without an approved permit set, construction cannot legally start.
A typical residential permit set includes:
Our residential clients include homeowners, general contractors, real estate developers, and investors. Projects we regularly handle:
Whether you’re adding a bedroom, building a backyard ADU, or starting from the ground up, we handle the permit drawing process from start to finish.
California is where we do most of our work, and we have hands-on experience with building departments across the state:
Los Angeles Area: LADBS (City of Los Angeles), Beverly Hills, Santa Monica, Culver City, Burbank, Glendale, Pasadena, Long Beach, and most surrounding cities
San Diego Area: City of San Diego, Chula Vista, El Cajon, Santee, and neighboring jurisdictions
Inland Empire & Beyond: Corona, Riverside, Ontario, and other Southern California cities
Each California city has its own plan check process, specific formatting requirements, and correction tendencies. Working with a team that already knows these departments saves time and avoids the back-and-forth that slows most projects down.
We also serve clients in other U.S. states. Requirements and review processes vary significantly by jurisdiction, and we approach each project with the same attention to local code compliance regardless of location. If your project is outside California, contact us and we’ll confirm coverage for your area.
We keep the process simple and transparent from day one.
From receiving your project information to delivering permit-ready drawings, our typical turnaround is 2 to 4 weeks depending on project complexity.
City review times vary. Simple residential projects in some jurisdictions can be approved in a few weeks. LADBS and larger cities typically take longer, especially for full plan check. We’ll give you a realistic timeline estimate based on your specific city and project type during your consultation.
Yes across all disciplines. Our in-house team covers architectural, structural (civil), and MEP drawings, and we provide licensed PE stamps for all of them.
For California projects, we have licensed engineers for both structural/civil and MEP work. This means your full permit set architecture, structure, mechanical, electrical, and plumbing is prepared and stamped under one roof, with no need to source separate engineers or manage outside coordination.
This keeps the drawings fully coordinated, reduces errors between disciplines, and typically results in fewer correction comments from the city.

A good portion of the clients who come to us already have drawings but not drawings that work. They hired someone at a low price to put together a permit set, submitted it to the city, and got it back with a long list of correction comments. Now they’re stuck: the original designer can’t fix it properly, the city won’t approve it as-is, and the project is sitting still while carrying costs keep adding up.
We take those projects on regularly. We review the correction comments, identify what’s actually missing or wrong, and prepare a revised set that addresses everything the city flagged. It gets done but it takes longer and costs more than starting clean would have.
The clients who come to us at the beginning, with nothing more than a sketch or an idea, almost always have a smoother experience. We ask the right questions upfront, design around what the city will require, and build a permit set that’s complete the first time. They get their permit faster, and the whole process feels a lot less stressful.
150+ residential projects completed across California ADUs, additions, new construction, multi-unit, and more.
We know the cities. LADBS, San Diego, Beverly Hills, Santa Monica, Corona, and most Southern California jurisdictions. We know their requirements, their correction patterns, and how to prepare drawings that move through plan check efficiently.
Architecture and structure under one roof. Coordinated drawings with fewer errors, fewer correction cycles, and faster approvals.
Real support through plan check. We don’t disappear after delivering drawings. We stay involved until your permit is approved.
For most residential projects, yes a licensed architect or engineer must prepare or review the drawings. For some smaller single-family projects, there are exemptions, but any structural work requires a licensed PE. We’ll clarify what’s required for your specific scope during the consultation.
We handle that regularly. Share the correction notice with us and we’ll review it, address the issues, and prepare a revised submission.
Yes. While California is our primary market and where we have the deepest local knowledge, we work with clients in other states as well. Contact us with your project location and scope and we’ll confirm what we can cover.
A description of your project, property address, any existing drawings or photos, and a sense of your timeline. We’ll guide you through the rest.
