An in-law suite adds flexibility, value, and family support to your Hartford County home. We build complete in-law suites: basement conversions, above-garage additions, attached additions, or garage conversions to living space. Every suite includes framing, insulation, drywall, electrical, plumbing, HVAC, flooring, painting, a full bathroom, and either a kitchenette or full kitchen.

In-law suites require careful planning. Connecticut zoning and building codes govern separate living spaces, accessory apartments, and occupancy limits. We navigate these requirements so your suite is code-compliant and legally recognized. We also ensure proper separate entrance, utilities, and kitchen/bathroom infrastructure so the space functions independently.

Every in-law suite project begins with a site assessment. We discuss your family's needs, review the space (basement, garage, or addition site), and develop a design that maximizes functionality. Permits are handled by us, and we manage the entire construction process from frame-up through final inspection and move-in. Accessory apartment rules vary town to town across Hartford County, so we confirm the specific zoning ordinance for your address before we design the layout, not after.

Every TJ's in-law suite is quoted on-site, and you approve the price before we start. Free on-site estimate with no obligation.

Our Process

01
Space Assessment & Design

We evaluate the space (basement, garage, or addition footprint), discuss zoning/code requirements, and design a functional layout with separate entrance, bathroom, and kitchen. You approve the design and budget before permits are pulled.

02
Permits & Prep

We pull permits, mark utility locations, and prepare the space. Connecticut code requires proper egress, kitchen facilities, and separate utilities. We ensure all requirements are met.

03
Structure & Systems

Framing, insulation, drywall, electrical, plumbing, and HVAC are installed. Bathroom and kitchen rough-in happens systematically so all systems coordinate.

04
Finish & Move-In

Flooring, cabinetry, fixtures, and painting are completed. Final inspections confirm code compliance and occupancy approval. The suite is ready for your family.

Frequently Asked Questions

What types of in-law suites do you build?

We build basement conversions, above-garage additions, attached side additions, and garage-to-living conversions. Each has different challenges and codes. Basements offer budget efficiency; additions offer more control. We discuss your space and your family's needs to recommend the best approach.

Do in-law suites require permits in Connecticut?

Yes. Separate living spaces are subject to building code and zoning. We handle all permitting. Requirements vary by town (some allow accessory apartments; others restrict). We know the local codes and ensure your suite is compliant.

Can the suite have its own kitchen?

Yes. A full kitchen is possible and creates a truly independent living space. We can also design a kitchenette (smaller kitchen, minimal appliances) if space or budget is tight. Full kitchen adds cost but increases functionality and independence.

What about heating and cooling?

Basement suites can use the main home's HVAC with zone controls, or we install a separate mini-split system. Additions typically tie into the main HVAC or get an independent system. We discuss options and costs.

How long does an in-law suite take to build?

Timeline depends on type. Basement conversion: 6-10 weeks. Above-garage addition: 8-12 weeks. New addition: 10-16 weeks. Complexity, weather, and permit timing affect schedules. We provide a clear timeline after the design phase.

Can we use an in-law suite to generate rental income?

Rental use depends on local zoning. Some towns allow long-term accessory rental; others restrict it. We build to code, but you should verify local zoning rules about rental occupancy. Speak with your town zoning board before committing.
