Residential Old Town has rules about how large houses can be as well. They determine whether new buildings need to be for a single family only or whether duplexes, or sometimes even larger multi-family units, can be built. The rules also determine how many square feet the house can have based on the overall size of the lot that the house is being built on. These rules determine "mass and scale" for additions and new houses.
|Don't miss the fact that there's an older house tucked in the shadow on the north side of these two much larger homes.|
NCM: Lot Size < 4000 House Size ≤ (Lot Size) x .50
NCM: Lot Size < 6000 House Size ≤ (Lot Size) x .25 + 1000
NCM: Lot Size ≥ 6000 House Size ≤ (Lot Size) x .25 + 1000 + 250 (towards detached garage)
NCL: Lot Size < 5000 House Size ≤ (Lot Size) x .40
NCL: Lot Size < 6000 House Size ≤ (Lot Size) x .20 + 1000
NCL: Lot Size ≥ 6000 House Size ≤ (Lot Size) x .20 + 1000 + 250 (towards detached garage)
And if you look at just the NCM on the westside of Old Town, this is what that looks like when you look at where houses fall in terms of FAR.
Most houses (the blue dots) are well below the limits (both the old limits and the new limits - both shown with red lines). The new FAR rules only keep a few of the largest houses from being built. The change in the FAR is really quite modest.
