Santa Rosa homes start at $1m in PHR. I have the price sheet right here with the FAQ that spells out the monthly fees:

Is there an association?
Yes, there are 2: West Santa Rosa Community association is currently $55/mo and will rise to a minimum of $150/mo at buildout. West Highlands Pacific Homeowners association is $35/mo.

Is there a CFD?
Yes, there are 2: Solana Beach school district at $300/mo. San Dieguito Union High School district at $85/mo.

Let’s see:
HOA: $35 + $150 (minimum at buildout) = $185
MR: $300 + $85 = $385
Total = $385 + $185 = $570.

Keep in mind that the $150/mo HOA is specified as a MINIMUM at buildout. So these fees start at $570/mo and could rise with the HOA costs.
