Where we build

Ten towns, each with its own answer to the same question. Every page below carries that town's actual rules with the source named beside each one, and says plainly which figures we have not been able to confirm.

The estate towns

Large lots, septic, geology and trees. Whole-house work leads here, with the second unit as part of the same permit set.

The Peninsula and the valley floor

Tighter lots and busier counters. Setbacks, daylight planes and coverage decide most projects here.
