ADUs Built for Bee Cave Lots, Start to Finish
Bayside Home Builders handles design, permits, and construction for accessory dwelling units in Bee Cave and the surrounding Hill Country, so you get a finished, livable structure without managing three separate contractors.
adu project · Bee CaveBee Cave Lots Make ADU Placement Harder Than It Looks on Paper
A Bee Cave lot that looks generous on a survey can have two-thirds of its buildable area eliminated before you draw a single line. Slopes that drain toward the rear yard, protected oak trees with critical root zones, HOA setbacks stacked on top of city setbacks, and utility easements running through the most logical building zones are all common on properties we evaluate here.
What you are living with
Homeowners who try to plan an ADU from a plat map alone usually hit a wall at permit submission or, worse, after they have already paid for architectural drawings. A site that seemed straightforward turns out to require a retaining wall, a pier-and-beam foundation instead of slab, or a redesigned footprint to clear a tree's root zone. That costs time and money that should have been accounted for at the start.
What you get instead
We walk the site before we draw anything. Slope, tree canopy, drainage flow, and easement locations all get mapped against your goals and budget in the earliest phase. That way the design we produce is one that can actually be built on your specific lot in Bee Cave, permitted through the city, and approved by your HOA if one applies.
Our Recent Work
Accessory Dwelling Units Built to Code, Built to Last
An ADU adds livable square footage to your property without buying a new lot. Whether you need a rentable unit, a guest suite, or a place for family, we handle the full project from permit drawings to final walkthrough.
Permit-Ready Design and Drawings
We produce the architectural drawings your local building department requires, sized and formatted to meet current zoning and setback rules for your property. You do not have to coordinate a separate architect.
Foundation and Structural Work
Detached ADUs get a properly engineered foundation matched to your soil conditions. Garage conversions and attached units get any required structural reinforcement so the finished space meets code for habitable square footage.
Full Mechanical, Electrical, and Plumbing Rough-In
We rough in all systems, coordinate inspections at each required phase, and use licensed trade partners for electrical and plumbing so every system is signed off before walls close.
Insulation and Energy Compliance
ADUs must meet the same energy codes as a primary residence. We install insulation, windows, and HVAC equipment that pass inspection and keep utility bills reasonable for whoever lives in the space.
Interior Finishes and Kitchen or Kitchenette
Flooring, cabinetry, countertops, fixtures, and trim are all included in our scope. We work from a finish schedule you approve before construction starts so there are no surprises at the end.
Site Work and Utility Connections
We coordinate water, sewer, and electrical tie-ins to the existing property service, handle any required utility upgrades, and restore disturbed landscaping so the finished ADU looks intentional, not tacked on.
Why Homeowners Choose Bayside for Their ADU
ADUs involve zoning research, permit coordination, and trade scheduling that most remodelers are not set up to handle well. Here is what we actually bring to the project.
We Pull the Permit, Period
We do not hand you a permit application and wish you luck. Our team prepares the drawings, submits to the building department, responds to plan review comments, and tracks the approval through to issuance. You stay informed without having to manage the process yourself.
Design-Build Under One Roof
Design and construction are handled by the same company, so the drawings we produce are priced by the crew that builds them. There is no gap between what the designer planned and what the builder can actually execute or afford to include.
Over 500 Projects Completed, Insured and Bonded
We carry full general liability insurance and are bonded on every project. With more than 500 completed projects behind us, we have encountered and solved the structural surprises, utility conflicts, and zoning edge cases that come up on real properties.
Fixed Scope Before We Break Ground
We do not start construction on a vague allowance budget. Before any work begins, you have a signed contract with a defined scope, a finish schedule you reviewed, and a timeline that accounts for permit lead time. Change orders happen when the scope changes, not because we underquoted to win the job.
How an ADU Project Works with Bayside
Most homeowners have never built an ADU before. Here is the straight sequence from your first call to handing you the keys.
Step 1: Site and Zoning Review
We start by reviewing your property, lot dimensions, existing structures, and local zoning rules to confirm what you can build and where. This step identifies setback requirements, size limits, utility connection points, and any restrictions that affect your options before you spend anything on design.
Step 2: Design, Pricing, and Contract
We develop a floor plan and scope of work based on what your site allows and what you need the space to do. You review the drawings, the finish schedule, and the project cost before signing. Nothing moves to permit submittal until you have approved the full plan.
Step 3: Permitting and Pre-Construction
We submit your permit package, respond to any plan review comments, and schedule trade partners once approval is in hand. Permit timelines vary by jurisdiction, and we set your expectations at the start based on current local lead times so the wait is not a surprise.
Step 4: Construction, Inspections, and Closeout
We build to the approved plans, schedule each required inspection, and do not close up walls until the rough-in phases are signed off. At completion, we walk the project with you, address any punch-list items, and hand you the final certificate of occupancy so the unit is legally habitable.
ADU Construction in Bee Cave, Texas
Bee Cave lots are not blank slates. Slopes, mature trees, Hill Country views, and HOA overlays all shape what you can build and where you can put it. We serve Bee Cave homeowners navigating those site constraints from design through final inspection.
Permits & review
Bee Cave is an incorporated city with its own development code, separate from Austin's ADU rules. That matters because City of Austin's Additional Dwelling Unit regulations do not automatically apply here. You will work through Bee Cave's building department, and if your subdivision has an HOA, that is a second approval layer on top of the city permit. We sort out which rules govern your specific address before design starts, not after.
Housing stock
Most Bee Cave residential lots were developed in the 2000s and later, so the housing stock skews toward newer construction in master-planned subdivisions. Many properties already have detached garages or large accessory structures that could be converted, or enough rear yard to support a new detached unit. Sloped terrain and protected heritage trees are the two site conditions that most commonly affect where a structure can land and what foundation type makes sense.
Areas we serve
We serve Bee Cave and the surrounding Central Texas communities including Lakeway, West Lake Hills, Spicewood, and the western Austin ETJ. If your address sits in unincorporated Travis County near Bee Cave, permit jurisdiction may shift to the county, and we handle that routing as part of our pre-design process.
Common questions
Are ADUs allowed in Bee Cave, Texas?
Yes. Bee Cave has its own municipal code separate from Austin, so ADU rules here differ from what you may have read about Austin's regulations. Setbacks, lot coverage limits, and utility connection requirements are all governed by the City of Bee Cave. We pull permits through the city directly and know what the current ordinances require before we draw a single line.
What does an ADU cost to build in Bee Cave?
For a ground-up detached ADU in Bee Cave, most homeowners are looking at somewhere in the range of $200,000 to $350,000 depending on size, finishes, and site conditions. Hill Country lots add real cost factors: rocky caliche soil, steep grades, and mature oak trees all affect foundation work and utility runs. A garage conversion on an existing slab will cost less, often $80,000 to $150,000, but you still need mechanical, electrical, and plumbing brought up to residential code. We give you an honest number before you sign anything.
How does the terrain in Bee Cave affect ADU construction?
Quite a bit. Bee Cave sits in the Hill Country where lots often have significant slope, shallow bedrock, and protected trees under the city's heritage tree ordinance. A sloped lot may require a pier-and-beam foundation or engineered retaining walls, which adds cost and time. We survey the site early so those conditions are priced into your estimate, not discovered after demolition starts.
What are the real drawbacks of building an ADU?
The honest ones: upfront cost is significant and financing can be tricky since most lenders treat it as a construction loan rather than a simple home equity draw. Permitting in Bee Cave adds time, typically several weeks to a few months depending on plan review backlog. If you have a difficult lot, site work costs can surprise you. And if you plan to rent it, being a landlord comes with its own management responsibilities. We walk through all of this with you before you commit.
How long does it take to build an ADU in Bee Cave?
From design through final inspection, plan on 9 to 14 months for a ground-up detached unit. A garage conversion moves faster, often 4 to 7 months. The biggest variable is permitting. City plan review, any variance requests, and utility coordination all happen before a single nail is driven. We start that process early and keep you informed on where things stand.
Can I convert my existing garage or structure into an ADU?
Often yes, and it is usually the most cost-effective path. The structure needs to meet current residential building code for insulation, HVAC, electrical, and plumbing, so the scope depends on what is already there. A two-car garage on a concrete slab in good condition is a solid starting point. We assess the existing structure first and tell you whether conversion or new construction makes more sense for your specific situation.
What do I need to know before I call a contractor about an ADU in Bee Cave?
Know your goals first. Are you housing a family member, creating rental income, or adding resale value? That shapes the size and finish level. Pull up your survey or plat if you have it so a contractor can eyeball lot coverage and setbacks. And be realistic about budget. In Bee Cave, a finished ADU that a tenant or family member can actually live in comfortably is not an inexpensive project. Any contractor quoting you a number well below the ranges above should explain in detail why their project is different.
