No HOA then the neighbors have no say. People have to mind their own business.
“No HOA”
Even with a HOA. They get to keep the ramp.
Even an HOA could not make them remove it.
The use of disability access ramps, sometimes referred to as handicap accessibility ramps, is governed by the Americans with Disabilities Act. Enacted into law in 1990, the Americans With Disabilities Act (or ADA for short) places very specific requirements on builders to allow easier access to those with disabilities. All new construction projects must meet the ADA standards when building disabled access ramps. -eHow
I don’t think even an HOA can trump the ADA lol.
