Accessory Building Construction Near You
LTA Construct designs and builds detached garages, backyard workshops, home studios, and other accessory structures — handled from permit to final inspection.
Whether you need covered parking, a dedicated workspace, or a guest suite above the garage, the right structure starts with the right builder.
What We Build: Accessory Structures of Every Kind
Accessory buildings cover a wide range of structures that sit separate from — or are attached to — a home's main footprint. LTA Construct has experience across the full spectrum, from simple single-car garages to finished ADU-grade accessory dwelling units with plumbing and HVAC.
Every project starts with a conversation about how you actually plan to use the space. A woodworking shop needs different ventilation and floor loading than a yoga studio. A carriage house converted to a rental unit has entirely different code requirements than a tool shed. Getting that clarity upfront is what separates a structure you love from one you outgrow in two years.
- Detached and attached garages (single, double, and tandem bays)
- Backyard workshops and hobby studios
- She-sheds, he-sheds, and multipurpose garden buildings
- Home offices and creative studios with electrical and data
- Carriage houses and above-garage living spaces
- Pool houses and outdoor entertainment structures
Local Permitting and What It Means for Your Project
In the Denver metro and Englewood area, accessory building permits are issued at the municipal level, and requirements vary noticeably from one jurisdiction to the next. Englewood operates under its own building department, while unincorporated Arapahoe County parcels follow a separate review process. Either way, accessory structures above a certain square footage — typically 120 to 200 sq ft depending on the municipality — require a building permit, a site plan showing setbacks, and in many cases an engineered footing design.
Colorado's climate adds layers that purely warm-weather markets skip. Roof structures here need to carry a significant snow load — the Front Range design standard commonly runs 30 PSF or higher depending on elevation and local amendments. Frost-depth footings are required to prevent heaving during freeze-thaw cycles, which means slab-on-grade slabs poured without proper depth will crack and shift. LTA Construct accounts for these factors in every accessory build rather than treating them as optional upgrades.
Neighborhoods in older sections of Englewood — particularly those with lots platted before modern setback ordinances — sometimes have limited buildable area in the rear yard. We review lot dimensions and HOA CC&Rs (where applicable) before design work begins so there are no surprises at permit submittal.
- Setback requirements vary by zone — typically 3–5 ft from property lines in residential districts
- Snow load and frost-depth compliance required for all permitted structures
- Some Englewood lots trigger alley-access garage placement rules
- ADU-level accessory buildings may require utility connections and separate inspections
How the Build Process Works
After an initial walkthrough of your property, we put together a scope that covers structural approach, materials, and the permit path. For straightforward structures, that can move quickly. For anything with living space, plumbing, or significant electrical, the permit and plan-review phase takes longer — and we set realistic timelines so you are not caught off guard.
Materials selection happens early because it affects both cost and timeline. Wood-frame construction is the most common approach for residential accessory buildings in this area. Steel framing is an option for larger spans or when the owner wants maximum interior clear height. Exterior cladding choices — LP SmartSide, fiber cement, board-and-batten wood, brick veneer — are driven by what matches the main home and what performs in Colorado's UV and hail environment.
Throughout construction, you have a direct line to the person running your project, not a rotating cast of office contacts. Inspections are scheduled and tracked by us; you get updates at each stage milestone.

Questions to Ask Any Accessory Building Contractor
Not every contractor who advertises accessory building construction handles the full scope. Some framing crews do not pull permits. Some handyman operations build structures that do not meet load requirements and cannot legally be financed or insured as part of your property.
When you talk to any contractor about this work, ask who pulls the permit and whose license is on it, how they handle engineering for footings and roof loads, and what their process is when an inspection requires a correction. These are not trick questions — a contractor with real experience in permitted accessory buildings will answer them without hesitation.
LTA Construct operates as a licensed general contractor, which means we take full responsibility for the structure and the permit, not just the framing labor.
- Is the permit pulled in the contractor's license name?
- Does the quote include engineering, or is that an add-on?
- What is the contractor's process for handling inspection corrections?
- Does the structure meet local snow load and frost-depth requirements?
Common Questions
Do I need a permit to build a detached garage or accessory structure?
In almost every municipality in the Denver metro area, yes — any accessory building above roughly 120 to 200 square feet requires a building permit. The exact threshold depends on your specific city or county. Skipping the permit creates real problems: unpermitted structures can block a home sale, void your homeowner's insurance coverage on that structure, and may need to be demolished at your expense if discovered. We handle the permit process as part of every accessory building project.
How long does it take to build an accessory structure from start to finish?
Timeline depends heavily on complexity and how long your local building department takes to review plans — that review phase alone can run anywhere from a few weeks to two or more months depending on the jurisdiction and current workload. A simple detached garage might move from permit approval to completion in three to five weeks of active construction. A finished workshop with electrical, insulation, and HVAC will take longer. We give you a realistic schedule after the initial site review, not a generic estimate.
Can an accessory building be used as a rental unit or home office?
It depends on your zoning and how the structure is built. Many residential zones in the Englewood area now allow accessory dwelling units (ADUs), but they come with specific requirements around minimum square footage, separate utility connections, egress windows, and sometimes owner-occupancy rules on the main property. A home office or studio that is not rented as a separate dwelling has fewer code hurdles. We can help you understand what your specific lot allows before you commit to a design.
