Guest Cottage / Casita
A private, finished space for family and guests — not a glorified storage room. Full bathroom, real insulation, climate control, and a door that locks. Your in-laws can stay a week without anyone crowding the main house.
Guest Houses & ADUs · Georgetown & Williamson County
A Guest Cottage. A Rental Unit. A Studio. Whatever Your Georgetown Lot Needs It to Be.
Detached accessory structures are one of the most versatile investments a homeowner can make — and one of the most underbuilt. Chance Leigh designs and builds guest houses, ADUs, and custom outbuildings in Georgetown and Williamson County to the same standard as the main house.
What It Can Be
One Structure. Unlimited Possibilities.
The right detached structure can serve a dozen different purposes over the life of your property. Chance has built all of these — to the same standard as a primary residence.
Income-Producing ADU
A permitted, self-contained rental unit that adds a second income stream to your property. Built to city code, properly connected to utilities, and finished to attract the tenant you actually want — not just the one who'll tolerate a converted garage.
Home Office or Studio
A detached workspace with its own address and its own front door. No commute, no colleagues walking through your kitchen. Whether you need a quiet office, a photography studio, or a music room, a separate structure makes it real.
Custom Workshop or Garage
A proper building for car collections, serious woodworking, or equipment storage — with real electrical panels, conditioned air if you want it, and a foundation that won't crack. Built like a building, not assembled like a kit.
Multigenerational Suite
Aging parents on the same property — close enough to help, separate enough for everyone's dignity. A finished detached suite gives your family options that a nursing home never will. See our multigenerational home page for more.
Estate Outbuilding
On larger ETJ lots outside city limits, there are fewer restrictions on what you can build and where. Pool houses, barn-style event spaces, caretaker quarters — Chance builds estate outbuildings that complement the land and hold their value for decades.
Why a Detached Structure
More Than Extra Square Footage
A detached structure isn't just a building you add to your property. It is an investment that compounds differently than the main home — because it can serve a completely different purpose in year one than it does in year ten.
Most homeowners underestimate what they'll use it for until they have one. Most builders underestimate what it takes to build one correctly.
Flexibility
It can be anything now and anything else in ten years. The casita you build for your mother-in-law becomes a rental when she passes. The studio you use while working from home becomes a guest suite when you retire. A well-built detached structure adapts to your life as it changes — which a subdivision floor plan never will.
Value
A permitted, finished accessory structure adds real square footage and real rentable or usable space without requiring you to move. Buyers in the Georgetown market increasingly look for properties that already have secondary structures — and they pay more for them. What you build today changes what your property is worth tomorrow.
Chance Builds It Right
Same subcontractors. Same framing standards. Same attention to the details that actually matter — insulation, electrical, plumbing rough-in, foundation. Chance currently holds a city permit for a 572 sq ft accessory building with full electric and plumbing at 609 W 15th St in Georgetown. [CONFIRM STATUS: the remodels page says this project is completed — pick one status and match both pages] This is not a DIY shed project. It is a real building built by the same team that builds the main home.
What's Involved
Permitting, Utilities & the Stuff Most Builders Skip
Accessory structures in Georgetown are subject to city zoning regulations — setback requirements from property lines, maximum allowable square footage, utility connection rules, and in some cases owner-occupancy requirements for ADUs that generate rental income. None of this is simple, and the rules differ depending on your zoning district, your lot size, and whether you're inside city limits or in the ETJ.
Chance manages all of it. That means pulling the correct permits with the City of Georgetown or Williamson County, coordinating foundation engineering for the smaller footprint — which requires its own geotechnical consideration — and running utility connections in a way that is code-compliant and finished properly. Electric and plumbing aren't afterthoughts on a Chance Leigh structure. They're planned from the beginning.
If you have a property in Georgetown or Williamson County and you're wondering whether a detached structure is feasible — the lot size, the zoning, the setbacks, the utility hookup — the fastest path to an answer is a direct conversation with Chance. He can tell you in one call what would work and what wouldn't.
