"I can’t say enough good things about INNOVATIVE BUILDERS HI! From start to finish, working with them was an amazing experience. I hired them for our home, and they exceeded all my expectations. First off, Chris the owner has an incredible knowledge of Hawaiian construction techniques, which was really important for me since I wanted to make sure the project aligned with local regulations and environmental considerations. He also has a great eye for detail, ensuring that everything was not only functional but also aesthetically pleasing, blending seamlessly with the beauty of our Hawaiian surroundings. The team was professional, courteous, and respectful throughout the entire process. They kept me updated at every step, made sure the site was clean and safe, and worked efficiently to stay on schedule.

I build beautiful, structurally sound, safe custom decks. The decks that I’m building are about you, not me. I pride myself in never changing a bid once I’ve submitted it. What I bid is what you pay, unless you change it by requesting additional features. I’m not the cheapest journeyman master carpenter you can find: but I will always give you more than your money’s worth. Collapsing decks are a major summer safety problem. Not only do I build structurally sound, safe decks, I will treat your home like it’s my own. My worksites are clean and safe at all times.

"Do not buy a Kodiak home. My floor plan was wrong. They didn't send me my insulation and have been trying to get a refund for 2 years. They also charged me 15% more after the plans went to manufacturing. This has been a nightmare to say it mildly. There are other steel frame home companies out there."

Addition to existing structure building services FAQs

Most ADU projects require several months from initial planning through final inspection. The timeline includes designing plans, securing permits, site preparation, construction, and finishing work. 

Factors affecting duration include project complexity, contractor availability, weather conditions, and local permitting processes. Planning for potential delays due to material shortages or inspection scheduling is advisable when establishing your project timeline.

Homeowners can access various funding sources for ADU projects. Home equity loans and lines of credit leverage existing property value, while construction loans provide phased funding specifically for building projects. Some areas offer specialized ADU financing programs with favorable terms. 

Personal loans might work for smaller conversions, though they often carry higher interest rates. Your financial situation, credit profile, and project scope will determine which option provides the most advantageous terms.

Adding an ADU often increases your property's assessed value, resulting in higher tax obligations. The specific impact varies by location, as assessment methods and tax rates differ between jurisdictions. Some areas offer temporary exemptions or gradual increases to ease the financial transition. 

For accurate projections, consult your local tax assessor before beginning construction to understand how your specific project will affect future tax bills.

Short-term rental regulations vary dramatically between municipalities. Some jurisdictions permit vacation rentals with minimal restrictions, while others impose occupancy limits, licensing requirements, or outright prohibitions, particularly for ADUs. Many areas require owner occupancy of the primary residence when renting an ADU short-term. 

Research your local ordinances thoroughly before planning rental income, as non-compliance penalties can be substantial.

The ADU construction process frequently encounters obstacles, including complex permitting requirements, unexpected site conditions requiring additional work, contractor scheduling difficulties, and budget management challenges. Many homeowners underestimate the complexity of coordinating multiple specialized trades. 

Additionally, ensuring adequate privacy between the main residence and ADU while maintaining aesthetic cohesion requires careful planning. Thorough preparation and working with experienced professionals can help navigate these common pitfalls.

Identifying qualified ADU contractors requires targeted research. Begin by seeking recommendations from neighbors with completed ADU projects or contacting local builder associations for specialist referrals. Review contractors' portfolios specifically for ADU or small residential projects similar to your vision. 

When interviewing potential candidates, assess their familiarity with local ADU regulations, ask about recent similar projects, and request contact information for past clients with comparable projects.
