ADU

ADU

Adding an ADU or a room onto your home should not feel like a gamble. With Garrison Partners, you get vetted local pros who arrive inside the window they gave you, a written price before a single nail is driven, and a full year of written guarantee on the finished work. No no-shows. No prices that move at the door. Just a disciplined crew from an independent local company that agreed to hold itself to The Garrison Standard, so your project comes in on time, done right, and backed in writing.

What’s Included

Every ADU and room-addition project we take on runs through the same squared-away process, no matter the scope. Here is what the Fielding ADU Builders team handles for homeowners:

Backyard ADU Construction

A detached unit in your backyard gives you a rental, a home office, or a place for aging parents without changing your main house. We build conventional ADUs with James Hardie siding, and we are fluent with leading prefab and modular platforms including Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. That range means we match the right build method to your lot, your timeline, and your budget instead of forcing one approach on every yard.

Garage Conversions

Turning an existing garage into a livable ADU often costs less and moves faster than a ground-up build. We assess the slab, the electrical service, the ceiling height, and the setback requirements before we ever hand you a number. You get a written price that covers all of it, permits and inspections included, so the day-one number matches the final invoice.

Attached ADU Additions

An attached unit that shares a wall with the main house works well on tighter lots where a detached build would not pass setback rules. We frame, rough in, insulate, and finish these additions with the same one-year written guarantee we give on every project. The crew on your site is background-checked and uniformed, so you always know exactly who is working on your property.

Junior ADUs

A junior ADU, or JADU, is a smaller unit created within the footprint of your existing home, often from a spare bedroom with its own entrance and a small kitchenette. These conversions typically move through permitting faster than a full separate unit. We explain what your specific city and county require, then do the work by the book the first time.

Room Additions

A single room addition expands your living space without a full ADU. We handle the foundation, framing, roofing tie-in, electrical, plumbing, drywall, and finish work as one priced job. The written quote you approve before the work starts is the number on your final invoice, period.

Prefab and Modular ADU Installation

For homeowners who want a faster path, we install and finish prefab units from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. We manage site prep, foundation work, utility connections, and the final finish so the unit is ready to occupy. Because we know these platforms by name and by spec, we can tell you up front what the site work will cost alongside the factory price.

Tuff Shed and Studio Conversions

A Tuff Shed-style structure can become a finished studio or workspace with the right permitting and build-out. We upgrade framing, insulate, pull electrical, and finish the interior to living-space standards where local codes allow. We will not promise a conversion your jurisdiction will not permit, and we will tell you that before you spend a dollar.

Why Homeowners Choose the Garrison Partners Family

The Garrison Partners family has been building to The Garrison Standard since 2006. That standard is not a marketing slogan. It is a written promise: we arrive inside the window we gave you, put the price in writing before any work starts, do the job by the book the first time, leave the site clean and squared away, and stand behind the work for a full year. If something fails inside that year, we come back and make it right at no charge. The name comes from the military garrison, the unit stationed to protect a place and keep it ready around the clock. The same idea drives every independent local company in this family. The crew on your property is background-checked and uniformed, verified before they ever set foot on your site. And when you call, a live person answers, whether it is noon or midnight. Homeowners who are worn out by no-shows and moving prices tend to notice that difference fast.
