Adding an ADU, converting a garage, or building a home addition in Boerne means working with limestone walls, Hill Country flash floods, and a Historic Landmark Commission that reviews every roofline near Main Street. The work here is different from what you’d find 30 minutes south in San Antonio. We plan for drainage before we pour, match German stonework when the lot demands it, and give you a written price before a single tool leaves the truck. If you’re weighing your options for a backyard unit or extra living space, call (210) 981-6358 and we’ll walk you through what’s realistic on your lot.
Why Boerne Homes Are Different
Boerne’s housing stock splits into two worlds. Older homes near Main Street and the historic district sit on smaller lots with aging utility lines, original limestone facades, and design review that cares deeply about what a new structure looks like from the street. Newer master-planned communities out on former ranchland have HOAs with their own setback rules, drainage requirements, and architectural committees. Neither job is like the other, and both reward a builder who reads the full picture before quoting.
The climate writes its own set of rules. Summers push cooling loads hard, so we size HVAC for a Hill Country August, not a national average. Spring and fall storms can drop enough rain to turn Cibolo Creek-adjacent lots into flood concerns, which means foundation elevations and swales get figured into the price instead of discovered halfway through the build. Homeowners near the historic district often need a Historic Landmark Commission review, and we’ve learned to plan for that timeline rather than pretend it doesn’t exist.
Our Main Boerne Services
The three jobs Boerne homeowners call us about most are home additions, garage conversions, and freestanding ADUs. Each has its own Boerne page with local pricing and specifics – here’s the short version.
Home Addition Contractor in Boerne
A home addition in Boerne usually means adding a primary suite, a second living area, or a home office to an existing limestone or Craftsman-style house. The job starts with matching the roofline and stonework so the addition doesn’t look bolted on. We also check what the existing utility panel and foundation can actually carry, because older homes near the historic district often need upgrades before new square footage goes up. If you’re planning to stay in the house during the work, we protect floors, keep dust contained, and clean up before the crew leaves each day. See the full breakdown on our Home Addition Contractor in Boerne page.
Garage Conversion Contractor in Boerne
Converting a garage in Boerne is a practical way to add a bedroom, rental unit, or in-law suite without touching the footprint of the house. The local challenge is that many Boerne garages were never insulated or sealed for living space, and some sit close to the property line in ways that affect setback approval. We handle the insulation, drywall, HVAC, flooring, and the paperwork, and we’ll tell you up front whether your garage is a clean conversion or needs structural work first. Details and Boerne-specific pricing live on the Garage Conversion Contractor in Boerne page.
ADU Builders in Boerne
A freestanding ADU on a Boerne lot is a new home on your property – one that can house aging parents, adult kids, or a tenant paying Boerne rent. The city’s growth and design guidelines make ADUs a real option for adding income while keeping the property’s character intact. We work with prefab and modular brands including Plant Prefab and Abodu, which can shorten the on-site construction window and reduce disruption to your family’s routine. For lot-specific guidance, start with the ADU Builders in Boerne page.

FAQs About ADU Company in Boerne
If your property is within the downtown historic district, yes – design review focuses on preserving 19th-century German stonework, rooflines, and street-facing character. We include that review in our planning from day one and build the timeline around it, so you’re not surprised by a delay later.
Low-lying lots near Cibolo Creek may require elevated foundations, drainage swales, or flood-resistant materials. We check FEMA maps and local drainage requirements before quoting, and we build the cost into your written price rather than flagging it as a change order mid-project.
For a detached ADU, most work happens in the backyard and daily disruption is limited. For home additions and garage conversions, our crews follow the Cedarwell Care Promise: shoe covers and drop cloths inside, pet-safe products where there’s a choice, and a photo of the clean-up before the crew leaves each day.
