In Watertown, building permits go through the city's Inspectional Services office, which requires one for most work on or in a structure, and since its list of exceptions doesn't name driveways or patios, that's a question we put to the Inspector of Buildings before we set a date. Bigger jobs like new construction or an addition can need approval from Zoning or the Department of Public Works before the building permit, so foundation work usually has an extra step ahead of it. Before work starts, we check with the city about the permits your job may need and help you get the paperwork in order.
What moves the price on a Watertown job is mostly what you can't see once it's poured. That's how much old concrete we break out and haul away, how much soft ground we dig out and replace with packed base, and how far the crew carries material on a narrow lot. The finish matters too, from a broom finish, the light brushed texture that gives feet and tires some grip, up to stamped patterns, while the schedule turns on the permit answer and the curing wait, and you get your own figure and dates at the estimate. We're based in Boston, a short drive away, and we see the same older lots and tight side drives across the cities around it.
