Pricing & Cost FAQs
An ADU in San Antonio typically starts around $120,000 for a compact studio and runs to $280,000 or more for a two-bedroom unit with full kitchen and laundry. Your actual price depends on size, site conditions, foundation type, utility connections, and finish level. We give every homeowner a written line-item price before any work starts, so you'll know exactly where the money goes. Ben Ortega and our local team can walk you through what's realistic for your lot. Call (210) 981-6358 for a free estimate.
A converted garage or a small prefab studio is usually the most affordable path, often landing in the $90,000 to $130,000 range depending on the condition of the existing structure and the plumbing and electrical work required. Prefab options like Boxabl or Tuff Shed shells finished out as living space can save labor time compared to full custom builds. We'll show you the cost difference between prefab and stick-built before you commit. Call (210) 981-6358 and we'll price both approaches.
Yes, our written price includes permits, utility hookups, foundation work, and the finishes we agree on, item by item. San Antonio's permit fees for ADUs vary by project scope, and we include those in your quote so there are no surprises later. If anything on the itemized quote changes, we explain the new price before the work continues. That's part of the Cedarwell Care Promise. Call (210) 981-6358 for a line-item estimate on your specific lot.
Permit fees in San Antonio for an ADU usually run between $1,500 and $5,000 depending on project valuation, plan review requirements, and impact fees. Your written estimate includes every permit fee we expect, and we pull the permits and schedule the inspections ourselves. No hidden charge appears later. If you want to know the exact fee estimate for your project, call (210) 981-6358 and we'll walk you through it.
The main drivers are square footage, number of bedrooms, kitchen and bath count, foundation type, site access, utility distance, and finish level. In a neighborhood like Terrell Hills or Alamo Heights, lot constraints and access can add cost. In Timberwood Park or Floresville, longer utility runs sometimes do. Also, a detached new build costs more than a garage conversion. We'll break each of these into line items so you can choose where to spend. Call (210) 981-6358 for specifics.
No, not without your approval. Our process is a written price before any work starts, and if we uncover something unexpected, like soil conditions or old wiring that changes scope, we explain the new price and get your sign-off before proceeding. You're never surprised by a change order. That's how Ben Ortega runs every project in San Antonio. Call (210) 981-6358 to talk through how your quote would be structured.
Service & Process FAQs
Most ADUs in San Antonio take 4 to 8 months from permit application to final inspection. Prefab units like Plant Prefab or finished Tuff Shed shells can shorten that to 3 to 5 months, since much of the framing and finishing happens off-site. Custom stick-built ADUs with upgraded finishes tend toward the longer end. Your timeline depends on city plan review speed, weather windows, and your finish choices. Call (210) 981-6358 and we'll give you a realistic schedule.
Yes, we pull every permit, schedule every inspection, and stay on site until the final sign-off. San Antonio's Development Services Department has specific ADU requirements, and our team knows the process well. You won't chase paperwork or wait on hold with the city. If a correction is needed, we handle it and explain what changed. Call (210) 981-6358 and we'll tell you what permits your project needs.
Most single-family lots in San Antonio can accommodate an ADU, but setbacks, lot coverage limits, and utility easements vary by neighborhood. Homes in Helotes, Boerne, and Fair Oaks Ranch may have HOA or deed restrictions to check. We review your lot, the zoning, and any HOA rules before you spend money on designs. Call (210) 981-6358 with your address and we'll tell you what's possible.
We do both. Garage conversions are often the fastest and most cost-effective ADU path in San Antonio, especially in older neighborhoods near downtown where lots are tighter. Detached new builds give you more layout flexibility and are common in areas like Cibolo, Selma, and Universal City where lot sizes allow it. We'll help you compare the two for your property. Call (210) 981-6358 to discuss which makes sense for your home.
You call, we visit your lot, we discuss your goals and budget, then we produce a written line-item price. Once you approve, we handle design, permits, and construction. During the build, we work to the Cedarwell Care Promise: shoe covers and drop cloths inside the house, quiet tools when the kids are asleep, pet-safe products where there's a choice, and a photo of the clean-up before we leave. Call (210) 981-6358 to start.
Design and permitting in San Antonio usually takes 6 to 12 weeks. That includes site measurements, plan drawings, engineering if needed, HOA review if applicable, and city plan review. Some neighborhoods, like Scenic Oaks or Timberwood Park, may have additional architectural review that adds time. We'll give you a week-by-week schedule before you commit. Call (210) 981-6358 for a timeline on your project.
Brands & Parts FAQs
Yes. We work with homeowners who want a prefab shell or a panelized build, and we've installed Boxabl and Plant Prefab units in the San Antonio area. Prefab can reduce on-site construction time and sometimes lowers overall cost. We'll handle the site prep, foundation, utility connections, and finishing so the unit is move-in ready. Call (210) 981-6358 and we'll compare prefab versus custom for your lot.
Yes, with the right planning. A Tuff Shed shell can be converted into a small ADU when the foundation, insulation, electrical, plumbing, and egress meet San Antonio's building code. This approach works best for compact studios and can save money over a full custom build. We'll assess the shed, the site, and the code requirements, then give you a written price to make it livable. Call (210) 981-6358 for details.
San Antonio's heat, humidity, and occasional hail storms make durability a real consideration. We often recommend James Hardie fiber cement siding because it handles our temperature swings, resists moisture, and stands up to hail better than vinyl. It also holds paint well in our intense sun. We'll explain the cost difference between siding options and help you pick what protects your ADU long-term. Call (210) 981-6358 to discuss materials.
