We have 100 properties, 65 with homes (on about 3 miles of road in Downeast Maine). We charge three different fees.
one for an undeveloped property.
one for a property with a home.
one for a property with a home and adjoining undeveloped property. (We have several homes that have to have their septic systems on a different property)…(and a few that just didn’t want someone moving in next to them)… For these we set the property cost a little lower that that of just an undeveloped property.
we have one duplex, we charge that as two homes.
we charge the same for year round homes as summer homes. (Towns do not give summer homes a break on their property taxes).
note that if you use the fixed rate fee you have to be careful it does not exceed the 1% of assessed value rate set by Maine state law.
this has worked for us for 25 years. But personally I think setting fees like the towns do (a percentage of assessed value) would work better. When in doubt i alway ask, “what does my town do?” And that gives me a strong starting point to work from that our members can understand. And it helps to make the rules less arbitrary.
