Brown's Construction, Inc., provides the highest quality work at an affordable price. We listen to our customers needs and we execute their ideas to near perfection. Customer satisfaction is our number 1 goal!

"Great work when it is done right, but some mistakes should not be made. To completely frame the whole build crooked and have to tear down and rebuild is ridiculous. I am still dealing with water leak issues from the build. There were other projects i had planned for them, but I have had a change of heart. "

"My family experienced water and wind damage earlier this year. We had to be placed in a hotel. After reaching out to numerous companies, we chose Maynor construction. I am glad we did!! If it wasnâ t for Maynor and his staff, I wouldnâ t have made it. The process was long and depressing because of being away from home. However Maynor and his staff reassured me. They showed patience with me and worked hand and hand with my insurance company with getting my home repaired in a timely manner. Thank you Maynor! I truly feel like we are family!"

Work was completed in less than the time specified and the installer, Aaron was great to work with. Had a problem with the toilet after three months and they were great about coming back to fix it. The fix didn’t work though and instead of messing with another repair, they just replaced it with a brand new one. We would definitely recommend this company."

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.
