It would pencil 4 stories, same footprint (7 units, 4 stories), but only if land comes in at the low end of its range.

Not current law. "Same footprint" adds floors to the densest legal option, up to six stories, the most wood over a podium allows before concrete. Rezonings use that district's best current-law option on this lot. Construction above four stories is priced at 1.13× wood frame for wood over a podium and 1.28× for concrete.

what a new building here gets LIHTC rent cap, 60% AMI ($1,540) pencils only if land is cheap doesn't

Bars are the monthly rent per market-rate unit each option needs to pencil, from the low to the high end of the land price. The market tick is Zillow's rent for the area with the new-building premium. Zillow rents trail the market and blend all bedroom sizes, while rent needed uses this building's own units, so the comparison is approximate on the market side. Light rows are hypothetical, not current law.

stories

land construction (darker = podium, concrete or steel) soft costs taller than current law allows

4 to 5 stories: +$25k per unit (+9%), where the building becomes podium type and an elevator.
6 to 7 stories: +$44k per unit (+14%), where the building becomes concrete or steel.

The same footprint and unit sizes, one story taller each time, with land at $159k for the whole lot (the middle of the range above). Units and floor area scale with stories from the by-right building, so light columns show what a taller building would cost, not what zoning would allow. Planning-level only, like the pro forma.

Land: $96,810–$221,280 — the city's assessed land value, 0.7×–1.6×, where half of recent lot sales landed against it. The assessment is a fixed share of total value, not a land price; enter a better figure if you have one

Use my land price:

Cost per unit is land, construction and soft costs from the pro forma at each option's units, floor area and construction type, divided by its units. Rent needed is the average monthly rent per market-rate unit for a 6.0% yield on cost, the pro forma's "pencils" line, against what a new building in the area would get (neighborhood rent with the new-building premium, at delivery). On the Mixed-Income option the affordable units stay at their 60% AMI rent. Planning-level only, like the pro forma.

Elective: the project must provide moderate-income units under §14-702(7).
