Frequently Asked Questions - ADU in Pasadena, CA
Straight answers to the questions Pasadena homeowners ask us most about accessory dwelling units. If you don't see your question here, call (626) 657-5541 and we'll talk it through.
Pricing & Cost FAQs
A detached ADU in Pasadena typically runs $250,000 to $450,000, while garage conversions land between $120,000 and $220,000 depending on the condition of the existing structure. Your final number depends on square footage, site access, foundation work, and finish level. In neighborhoods like Bungalow Heaven and Madison Heights, we see costs shift based on how tight the lot access is and whether the garage slab needs reinforcement. Fielding ADU Pasadena gives you the price range in writing before any work starts, so the number doesn't move at the door. Call (626) 657-5541 for a free estimate with real line items.
Converting an attached garage is almost always the cheapest path to an ADU in Pasadena, because the roof, walls, and foundation are already there. The catch is that older Pasadena garages often need seismic retrofitting and new electrical service, which can add $15,000 to $40,000 faster than homeowners expect. A junior ADU inside the existing house footprint costs even less to start but comes with size limits. We walk every client through the trade-offs before they commit. Call (626) 657-5541 and we'll give you an honest cost comparison for your specific property.
Most of the gap comes down to what's left out of the low bid. Some builders price only the shell and leave electrical, permits, or site cleanup as change orders. Others don't include the foundation engineering your hillside lot might need. Fielding ADU Pasadena writes the full scope into your quote before you sign, including permits, plans, and the finish you actually chose. That's the Garrison Standard: price in writing before any work starts. If two quotes are $80,000 apart, one of them is missing something. We'll show you exactly what ours includes. Call (626) 657-5541 for a written estimate.
A complete ADU quote should include city permits, plan check fees, and utility hookups, but not every builder writes it that way. Pasadena Water and Power and SoCalGas each charge connection fees that can total several thousand dollars, and those hit you at different phases of the job. We line-item these costs in our written estimates so you're not surprised by a bill halfway through. Permits and inspections are part of doing the job by the book, the first time. Call (626) 657-5541 and we'll show you the full cost picture for your ADU.
Service & Process FAQs
We start with a site visit to confirm setbacks, access, and what the city will allow on your lot. Then we produce plans, submit them to the Pasadena Building & Safety Division, and pull permits once approved. Construction happens in phases: foundation, framing, mechanical, finishes, final inspection. Fielding ADU Pasadena keeps you informed at each step, and our crews arrive inside the window we gave you. The whole process from first meeting to final inspection usually takes 10 to 14 months depending on plan check timing. Call (626) 657-5541 to start with a free site visit.
Plan for 10 to 14 months from design kickoff to final inspection in Pasadena. The biggest variable is the city's plan check queue, which has run anywhere from a few weeks to a few months in recent years. Construction itself for a typical detached ADU takes 5 to 7 months once the permit is issued. Ground-up buildings in hillside areas like San Rafael Hills often run longer because of foundation and grading work. We'll give you a real timeline after the site visit, and we stick to it. Call (626) 657-5541 to schedule yours.
Yes. Permits, plan check, and inspections are part of our scope. The Pasadena Building & Safety Division has specific ADU standards, and a missed detail in the submittal can add weeks to your timeline. Our team prepares the drawings and documents the way the city wants to see them, submits everything, and manages the corrections cycle until the permit is issued. Doing it by the book, the first time is one of the five points of the Garrison Code we work under. Call (626) 657-5541 and we'll walk you through the permit path for your property.
In most cases, yes. Pasadena allows garage conversions when the replacement parking requirement is met or waived under state ADU law. We check the slab, the framing, and the roof before we quote, because a 1940s garage in Pasadena often has foundation issues you can't see from the outside. Where the structure is sound, a conversion can save you real money compared to building new. Where it isn't, we'll tell you straight and price the right fix. Call (626) 657-5541 for a no-pressure assessment of your garage.
An ADU gives you a rental unit with its own entrance, kitchen, and meter, which is a different financial equation than adding square footage to your main house. A second story adds value to your primary residence but can't generate rental income on the same timetable. In Pasadena neighborhoods zoned for single-family homes, ADUs are allowed on almost every lot under state law, which makes them the quicker permit path in many cases. The right answer depends on your goals. Call (626) 657-5541 and we'll help you think it through with real numbers.
Brands & Parts FAQs
We build stick-framed ADUs on site, but we've worked alongside prefab systems like Abodu and Cover when a homeowner brings that direction to the table. Prefab can shorten the on-site build phase, but it still requires foundation, utility, and permitting work that happens the same way as a traditional build. Some Pasadena lots have tight access that makes panelized delivery harder than it looks. We'll give you an honest read on whether prefab or stick-built fits your property better. Call (626) 657-5541 and we'll compare both paths for your lot.
We spec materials that hold up to Pasadena's dry summers and occasional heavy rain seasons. James Hardie fiber cement siding is a common choice because it handles the temperature swings and sun exposure without warping or fading. We also use stucco where the neighborhood calls for it, and we match the main house's character so the ADU looks like it belongs. Every material choice gets written into your estimate before work starts, so there's no substitution game. Call (626) 657-5541 to talk materials and get a written price.
Pasadena's Title 24 energy requirements mean your windows and doors need good insulation values, and the sun exposure on south-facing walls makes low-E glass worth the upgrade. Beyond code, you want hardware that holds up to years of tenant use, because an ADU door gets opened far more than a guest room door. We spec durable, thermally efficient windows and doors and include them in your written estimate. No allowances that run short, no surprise change orders. Call (626) 657-5541 to get the details.
The high-performance, factory-built approach brands like Dvele represent is an interesting path, and we're glad to talk about how it compares to a site-built ADU on your specific lot. Factory precision can mean tighter tolerances and faster assembly, but it comes with a different cost structure and less flexibility on design changes mid-project. For most Pasadena homeowners, the deciding factor is site access and how custom the layout needs to be. Call (626) 657-5541 and we'll give you a straight comparison based on your property.
Licensing & Insurance FAQs

We'd rather show you the paperwork than ask you to take our word. Call (626) 657-5541 and we'll answer any credential questions on the phone.

Emergency & Response FAQs
If your garage roof is sagging or a wall is bowing, treat it as a structural problem first and an ADU question second. A failed garage in Pasadena means your car, your storage, and your family's safety are all at risk from falling framing or shearing walls. Don't go inside a structure that's visibly failing, and don't try to shore it up yourself. We can assess whether the existing garage is a candidate for conversion or whether it needs a teardown and rebuild. Call (626) 657-5541 during business hours and we'll get you on the schedule.
Fielding ADU Pasadena is not a 24/7 emergency service. Our business hours are 7:00 AM to 7:00 PM Monday through Friday and on Sundays, closed Saturdays. If a garage or ADU structure is actively failing, secure the area, keep people out, and call us during business hours at (626) 657-5541. We'll prioritize a structural assessment and get your project moving. For life-threatening emergencies, call 911 first. We're a construction company that shows up when we say we will, and we'll be here during the hours we publish.
Once we complete the site visit, design, and permit submission, the start date depends on Pasadena's plan check queue and our build schedule. We don't pad timelines to make ourselves look good, and we don't overpromise a start date to win the job. You'll get a real window, and our crews show up inside the window we gave. That's the first point of the Garrison Code. Call (626) 657-5541 and we'll tell you what the calendar actually looks like for a project like yours right now.
Warranty & Guarantees FAQs
Every Garrison company works to the same standard: we arrive inside the window we gave you, put the price in writing before any work starts, do the job by the book, and leave the site clean. The work is guaranteed in writing for a full year, and if it fails in that time, we come back and make it right at no charge. That's the Garrison Standard, and it's stamped on every job we take. No fine print, no runaround. Call (626) 657-5541 and we'll show you the warranty language before you commit.
No, and this is where we earn our keep. The price is written before any work starts, with the full scope itemized. If you change the scope, say you upgrade the flooring or add a window, we write a change order and you approve it before the work happens. If we missed something in our own estimate, that's our cost to eat, not yours. Homeowners come to us worn out by prices that move at the door, and we built our process to be the opposite of that. Call (626) 657-5541 for a written estimate that means what it says.
The one-year written guarantee covers defects in our workmanship and materials installed by our crew. If a door starts binding, a roof leak appears at a penetration we installed, or a cabinet door pulls loose, call us and we come back and fix it at no charge. Normal wear and tear, tenant damage, and issues caused by neglect aren't covered, and we'll tell you that upfront too. The guarantee is part of the Garrison Standard every location works to. Call (626) 657-5541 if you have a warranty question on an existing job.
