Current Offers
Free Written Estimate for Your ADU or Garage Conversion
Every family in San Diego receives a written price before any work starts, and this offer makes that estimate completely free. You’ll get a line-by-line number for your ADU, garage conversion, or home addition so you can plan without surprises. No deposit required just to see the numbers.
Valid through March 31, 2027. Mention this offer when you call (858) 988-6447.
Free ADU Site Assessment and Brand Consultation
We work hands-on with Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie. This offer includes a free walkthrough of your lot to discuss which prefab or modular system actually fits your space, your setbacks, and your budget. You get a recommendation based on your property, not on what any single factory prefers to sell.
Valid through March 31, 2027. Mention this offer when you call (858) 988-6447.
Garage Conversion Feasibility Check at No Cost
If you’ve got a garage in Clairemont, North Park, or La Mesa that’s mostly storage, this offer covers a no-charge feasibility review. We’ll check ceiling height, foundation condition, electrical access, and setback requirements so you know early whether a conversion pencils out. You’ll leave the visit with a straight answer, not a sales pitch.

First-Time Customer Courtesy: Free Care Promise Walkthrough
If you’ve never built with Seedling before, we’ll include a free pre-construction walkthrough that documents exactly how we’ll protect your home during the build. That means shoe covers and drop cloths on every visit, pet-safe products where there’s a choice, and a photo of the clean-up before the crew leaves. You’ll see the Cedarwell Care Promise spelled out for your specific floor plan.
Valid through March 31, 2027. Mention this offer when you call (858) 988-6447.
Senior and Military Courtesy: No-Cost Permit Review
For San Diego homeowners aged 65 and up, and for active-duty or retired military families, we’ll review your permit path at no charge. San Diego’s ADU permit process varies by neighborhood, and we’ll map out what’s needed for your specific lot before you spend a dollar on drawings. This is our way of saying thanks, and it stacks with the free written estimate.

How to Redeem
Call (858) 988-6447 and tell the live person who answers which offer you’re calling about. We answer 24/7 throughout your project, so there’s no voicemail tree to navigate. We’ll book the visit at a time that works for your family, and a background-checked, uniformed technician will show up as scheduled. Bring or mention the offer name at the time of the visit, and it’s applied before any written price is prepared. That’s the whole process.
What Every San Diego ADU Special Includes
No matter which offer you choose, the fundamentals don’t change. You’ll receive a written price before any work starts, always. Every completed ADU, garage conversion, and home addition is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right. Our crews wear shoe covers, lay down drop cloths, and use quiet tools when we’re working near bedrooms or during school hours. A photo of the clean-up gets sent to you before the crew leaves, every single day. Ben Ortega, our owner, signs off on the Care Promise checklist before any project wraps.

A garage conversion often costs less upfront because the shell already exists, but an ADU gives you a fully separate address and more floor plan freedom. Call (858) 988-6447 and we’ll help you compare both paths with your lot’s actual dimensions in front of us.
