Home Addition FAQs

How much does a home addition cost in Chattanooga?

The cost of a home addition depends on several factors, including the size of the space, the type of addition, materials chosen, and existing site conditions. For example, an attic conversion will be priced differently than a full garage addition or a bathroom expansion. At Jason Painter Construction, we provide a detailed, customized estimate after your free consultation so you’ll know exactly what to expect in terms of cost and timeline.

Do I need permits for a home addition?

Yes. Most home additions in Chattanooga and the surrounding areas require permits and inspections to ensure the work meets all local building codes. Our team handles all permitting, scheduling of inspections, and compliance requirements on your behalf. This way, you can feel confident your addition will not only look great but also meet safety and legal standards.

Will my home addition blend in with the rest of the house?

Absolutely. One of our top priorities is to make your new space look seamless. We carefully match roofing, siding, windows, flooring, and interior finishes so your addition feels like a natural extension of your home—not an afterthought. Whether it’s an attic conversion, garage build-out, or a sunroom, we make sure the design complements your home’s existing style.

How long does a home addition take?

Most home addition projects take between 6 to 12 weeks, depending on the type of addition and its complexity. Smaller projects like a bathroom addition may be completed more quickly, while larger builds such as multi-room or garage conversions can take longer. During your consultation, we’ll give you a clear timeline so you know when to expect completion and can plan accordingly.

What is included in an attic addition?

An attic addition can be an excellent way to add usable square footage without expanding your home’s footprint. These projects typically involve adding proper insulation, flooring, drywall, ventilation, and lighting. Depending on your needs, we can design your attic addition as a guest bedroom, home office, or even a full living suite.

Do you handle garage conversions?

Yes, we specialize in both garage conversions and garage additions. A garage conversion is a great way to transform underused space into a guest room, home office, playroom, or rental unit. We handle everything from flooring and insulation to electrical and plumbing, ensuring your converted garage feels like a true part of your home.

Are bathroom additions possible in smaller homes?

Definitely. Even in smaller homes, we can design efficient bathroom additions that make the most of your available space. Whether it’s a half-bath for guests or a full master bath, our team creates layouts that maximize functionality while maintaining comfort and style.

What are the benefits of a sunroom addition?

A sunroom addition brings natural light into your home, creates an inviting space to relax, and provides extra square footage that can be used year-round. Sunrooms can serve as reading nooks, casual living areas, or bright dining spaces. They also add to your home’s overall resale value, making them a smart investment.

Do home additions increase resale value?

Yes. Home additions are one of the best ways to increase your property’s value. Buyers often look for extra square footage, updated bathrooms, and flexible living spaces, making additions like attics, garages, bathrooms, and sunrooms especially appealing. Even if you’re not planning to sell right away, you’ll benefit from the extra comfort and functionality your addition provides.

Can I live in my home during the construction?

In most cases, yes. We understand the importance of keeping your home comfortable and safe while work is being done. Our team takes steps to minimize dust, noise, and disruption by sealing off work areas and keeping the project as tidy as possible. We’ll communicate with you throughout the process so you’ll know what to expect each step of the way.
