Island Style House Plans

Accessory Buildings

This is my catalog of existing Accessory Building Plans. These plans were designed for projects here in Hawaii and I'm making them available for you to get ideas for you own projects, and in some cases I'll resell them for a very reasonable price.

If you find something you like, I'm willing to resell many of my existing plans for as little as $500 and usually not more than $2,000. Or perhaps you might just get some ideas for a custom design by looking through the catalog.

By the way, viewing these plans with a computer is much easier than viewing them on a hand held device, and Firefox is the best browser to use because it has a "Hand" tool that makes it much easier to move around when zoomed in. Access the Hand tool by selecting the double right arrows (>>) at the top right corner of the view window.

Contact me with the plan number you're interested in, explain what you want to do with it and I'll send you a quote.

About building codes

Codes are constantly changing and the plans here drawn before 2012 were created prior to the adoption in many jurisdictions of the International Building and Energy Conservation Codes. Most of these plans have not been fully updated to be compliant with the currently adopted codes here in Hawaii, but I can update them as needed. The first two digits in the plan number is the year they were drawn. The older plans are less compliant than the newer plans. Only the plans drawn since mid 2021 are fully compliant with all current codes. Plans drawn between 2016 and mid 2021 are somewhat compliant, however plans drawn prior to 2016 are mostly not compliant and would require substancial work to bring them into compliance with current codes. Hawaii County adopted the 2018 International Residential Code in September 2021. This latest code requires much higher structural resistance to lateral wind and seismic forces.  

About Revisions

I can also make revisions to the existing plans if needed. Contact me to discuss the desired revisions and I'll send you a quote. Note: My current schedule is about 5-6 months out to make revisions and code updates.

Additionally, if you're project is in Hawaii, I can draw a Site Plan for your property (which is required for permitting) showing the location of the home on your property and any other proposed improvements.
