Current Offers

Free Written Estimate for Any ADU Project
Every Pasadena homeowner who contacts Seedling ADU Pasadena receives a written line-item price before any work starts. No verbal ballpark followed by surprises later, no “we’ll figure it out as we go.” This applies to accessory dwelling units, garage conversions, and home additions of any size. Whether you’re exploring a Tuff Shed studio in Bungalow Heaven or a full two-bedroom prefab from Abodu in Hastings Ranch, you’ll see every cost on paper first. Valid through March 31, 2027. Mention this offer when you call (626) 657-5461.
Seasonal Design Consultation at No Cost
Sit down with Ben Ortega and walk through your Pasadena lot’s actual possibilities: setbacks, sun orientation, utility access, and which of the eight prefab brands we work with actually fits your site. Families in the San Rafael Hills face different slope and grading questions than flat-lot owners near Caltech, and this consultation is where those specifics get sorted out. You’ll leave with clarity on scope, timeline, and budget, not a sales pitch. Valid through March 31, 2027. Mention this offer when you call (626) 657-5461.
Garage Conversion Feasibility Review, Written and Included
Thinking about converting an existing garage in Pasadena? We’ll inspect the structure, check the slab, assess electrical capacity, and verify what Pasadena’s ADU ordinance requires for your specific neighborhood. You get a written summary of what’s feasible, what it costs, and what could go sideways, before you spend a dollar. Common in the Bungalow Heaven and Historic Highlands districts, where original garages often need structural upgrades to meet current codes. Valid through March 31, 2027. Mention this offer when you call (626) 657-5461.
Pre-Purchase ADU Site Assessment
This one’s for buyers eyeing a Pasadena property and wondering if it can actually support an ADU. Bring us the address, we’ll evaluate the lot’s ADU potential: zoning, access for construction crews, utility connections, and a realistic cost range based on comparable Pasadena projects. There’s no obligation, and having this report can save you from buying a house that won’t work for your plans. Homeowners near the Rose Bowl and Linda Vista often run into hillside constraints, and it’s better to know before escrow closes. Valid through March 31, 2027. Mention this offer when you call (626) 657-5461.
365-Day Done Right Promise, Included on Every Job
This isn’t a coupon, it’s the standing offer: if anything isn’t done right on your completed ADU, garage conversion, or home addition within 365 days of completion, we make it right. In writing, on every project, no exceptions, no fine-print exclusions for the things that commonly fail. No Pasadena homeowner should carry the risk of a contractor who disappears after final payment. Valid through March 31, 2027. Mention this offer when you call (626) 657-5461.
How to Redeem
Redeeming any Seedling ADU Pasadena offer is deliberately simple. First, call (626) 657-5461 and mention the specific offer by name; a live person answers, 24/7, throughout your project. Second, we’ll schedule the visit, consultation, or site assessment at a time that respects your family’s schedule. Third, we’ll give you the written price or written report on the spot. That’s it.
What Our Offers Actually Cover
Here’s what you get when you call (626) 657-5461 and book any Seedling ADU Pasadena service, whether you’re in the Arroyo Seco corridor, Chapman Woods, or up in the hills off Linda Vista:
- Written price before work starts. Always, on every project, with no surprise line items added after crews arrive. If it’s not on the paper, you don’t pay it.
- Background-checked, uniformed technicians. You’ll know exactly who’s walking through your door, which matters when kids are home from school or a dog is watching from the couch.
- Background-checked, uniformed technicians on every job. No subcontracted unknowns, no day laborers you’ve never met. Every person on your property is vetted and in a Seedling uniform.
- The Cedarwell Care Promise. Shoe covers and drop cloths inside your home, pet-safe products where there’s a choice, and a photo of the clean-up before the crew leaves. Your floors stay protected, your air stays clean, and your dog stays safe.
- Quiet tools and schedule respect. When work runs near bedrooms or during school hours, we use quieter equipment where possible and plan noisy phases around your family’s rhythm. Nap schedules and study time matter in Pasadena households.
- A live person on the phone, 24/7. During an active build, you’ll never hit a voicemail tree or wait until the next business day to talk to someone who can actually help.
Which ADU Brands Can You Choose From?
Seedling ADU Pasadena works hands-on with the brands Pasadena homeowners research before calling anyone: Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie materials. That’s eight distinct paths to a new home on your lot, and we’ll help you pick the one that matches your site and budget rather than the one we happen to prefer selling. A prefab Dvele unit makes sense for some lots in Madison Heights; a custom garage conversion often makes more sense for the narrow, deep lots in Normandie Heights. We walk you through the real trade-offs.
What Pasadena ADU Projects Actually Cost

Prices vary by scope, but here’s what we see across Pasadena in 2026 and 2027:
- Prefab studio ADU (Tuff Shed or similar): $140,000 to $190,000, depending on foundation, utility, and site work.
- Garage conversion to one-bedroom ADU: $120,000 to $180,000, with older Pasadena garages sometimes needing slab and electrical upgrades that push the higher end.
- Two-bedroom prefab ADU (Abodu, Cover, Dvele): $250,000 to $380,000, including delivery, crane work, and full utility connections.
- Custom home addition: $175,000 to $400,000, driven by square footage, foundation type, and whether we’re tying into existing systems or adding new ones.
These are planning ranges, not quotes. Your written price comes after we walk your specific lot and scope your specific project. Call (626) 657-5461 to schedule the free estimate and get numbers that apply to your address.
Why Seedling Runs Offers Without the Hype
Ben Ortega started Seedling ADU Pasadena because he kept seeing Pasadena homeowners get burned by vague estimates and builders who treated a $200,000 project like a handshake deal. Our offers aren’t designed to create false urgency. They’re designed to make it easy to start the conversation, get real information, and make a confident decision. If you call and decide an ADU isn’t right for your lot, you’ll still leave with clearer information than you had before. That’s the honest version of a special.
