Real, material, and not ours — paid to the jurisdiction, priced per parcel. We name every one of them.
What they areA range, until we see the lot
The one that really moves. Finish level, site conditions and access decide it.

Provisional.
Estimates for planning, not a quote — your feasibility report replaces every figure here with numbers for your actual property. The table scrolls sideways on a small screen.
Quoted per square foot and as a total, at the low and high end of the finish levels we build.

A range, deliberately.
Each total is the rate above applied to that band’s representative project, so a job at the top or bottom of a band lands outside it. Finish level, site conditions and access move this more than anything else on the page.
Twelve trades, adding to 100% of the construction cost — not of your total project.
100% of the construction cost, split twelve ways
Shares, not dollars. This is one standard allocation the workbook applies across every size and every category we price, so treat it as the shape of a ground-up build rather than a forecast of your own job.
Permit fees are paid to your jurisdiction, not to Fortune. They are set per parcel — by your city, your zone, your square footage, and which agencies have to sign off. A single average would be a guess with someone else’s money. So here are the fees a project like yours is normally asked for, what sets each one, and when you get the real amount.
We check every one of these against your address before you spend anything, and the feasibility report gives you the figures for your actual property. See what your city requires.
We check your lot, zoning and setbacks before you spend on drawings.
Architectural plans built to clear plan check, not only to look good.
Submittal, corrections and city liaison. We handle the reviewer.
Construction and project management through to final inspection.
Under an hour, no pressure — we talk through what your lot allows and give you a ballpark for your property. No charge, and no obligation to go further.
