There are 3 types of naming conventions for Form Modules. Each Form Module name is composed of a variety of components that are specific to that module.

1. House Form Modules

House Form Modules regulate building forms that resemble the form of a house, must not exceed 2.5 stories in height, and are composed of two components:

a. Building Width Category

Building width categories group all modules within a range of maximum allowed building width. House Form Module building width categories are organized as follows:

Narrow (≤40')
Medium (41'-60')
Broad (61'-80')

b. Form Modules apply to all portions of buildings and structures on a lot.

4. Nonconformity

Sec. 11100. Nonconformities provides exceptions from the requirements of Part 3.

A project activity must not decrease conformance with any Form standard unless otherwise specified by Sec. 11100.I. Form Exceptions . Consider the following examples:

a. An addition to the side of an existing building: Where a proposed addition increases the total building width beyond the maximum building width allowed by the applied Form Module, the addition is not allowed.
b. An addition to the top of an existing building: Where the height of the existing structure does not meet the building setback standard specified by the applied Form Module, all additional floor area must be located behind the minimum building setback, but no modifications to the existing upper stories are required.

Building Height

Sec. 390. Building

390.a. Building Height

The vertical dimension of a building or structure measured from average grade in feet and stories.

1. Intent

To provide adequate light, air, safety, and to protect the character of an area and the interests of the general public.

2. Applicability

The height limitations apply to all lots.

3. Standards

No building, portion of a building or structure can exceed the maximum height in number of feet or stories allowed in the zoning district, unless listed as an exception in S ec. 390.A.5 Exception.

4. Measurement

a. Height in Feet

Height in feet is the number of feet from average grade to:

The mid-point of the roof, for a building with a roof having a pitch greater than 4:12;
The top of the roof deck, for a building with roof having a pitch of 4:12 and less; and
The topmost point of the structure, for all other structures.

b. Height in Stories

Height in stories is measured as the number of stories above finished grade. The ground story and all upper stories are included in the calculation of maximum height in stories.
A story is the part of a building included between the surface of one floor and the surface of the next floor above, or if there is no floor above, then the ceiling next above. A mezzanine does not count as a story.
The ground story (or first story) of a building is determined as follows:
- i. The first (facade) story that is exposed a minimum of 6 feet above finished grade along the full width of the applicable building facade.
- ii. The finished floor of a ground story can be no higher than 6 feet above finished grade for any portion of the building perimeter. This may mean that the ground story may change within the same building.

- i. It is completely within the roof form of the building and less than 50% of the floor area has a clear height of more than 7.5 feet, measured from the finished floor to the finished ceiling; or
- ii. Dormers do not exceed more than 50% of the front, rear or side building length.

Where the sidewalk is more than 5 feet from the primary street lot line-facing building facade, average grade is calculated by averaging of the highest and lowest elevation within 5 feet of the primary street lot line-facing building facade.
Large buildings and those developed on sites with significant topographic variation may calculate average grade independently for each building module that steps up or down the slope.

d. Top Plate Height

Top plate height cannot exceed the maximum height in feet required by the zoning district and is measured from average grade to the top plate of the building.
