COUNCIL STAFF REPORT
CITY COUNCIL of SALT LAKE CITY
TO: City Council Members
FROM: Brian Fullmer
Policy Analyst
DATE: November 18 2025
RE: Text Amendment – RMF-35 & RMF-45 Multi Family Zoning District Update
PLNPCM2024-01388
BRIEFING UPDATE
During the October 7, 2025 briefing Council Members discussed current and proposed setbacks. Current
side yard setbacks are four feet on one side and 10 feet on the other. The proposal calls for four-foot side
yard setbacks on both sides (unless the property abuts single -family zoned parcels, then a 10-foot setback is
proposed).
Some Council Members expressed concerns with reduced setbacks in areas with small block sizes, and
potential loss of trees. Areas with small block sizes have some of the densest residential development in the
city. A question was raised about why the proposed changes are good for those living in these areas.
Planning staff noted the large number of homes that were constructed before zoning regulations were
adopted and are now nonconforming due to current setbacks. The proposal would help bring many of these
into compliance. Additionally, Planning discussed the potential for more affordable housing units in these
areas which could provide opportunities for younger people to live there without changing the
neighborhood character. It could also provide opportunities for current residents to age in place.
Council staff provided some context from when the RMF -35 and -45 zoning was created in 1995. At that
time the community wanted larger setbacks which resulted in many nonconforming lots. Housing supply
and costs are very different today and the pendulum has shifted to smaller setbacks .
Planning staff discussed additional height up to 55 feet if utilizing affordable housing incentives that was in
the original proposal. That was not supported by the community, so it was removed .
Item Schedule:
Briefing: October 7 , 2025
Set Date: October 21, 2025
Public Hearing: November 18, 2025
Potential Action: December 2 , 2025

The following information was provided for previous meetings. It is included again
for background purposes.
ISSUE AT A GLANCE
The Council will be briefed about proposed amendments to the RMF -35 (Moderate Density Multifamily
Residential) and RMF-45 (Moderate/High Density Multifamily Residential) zoning ordinance and map.
D evelopment of medium- to high -density housing types within the zoning districts has not happened since
their creation due to a variety of barriers and limitations. The proposed changes are intended to remove
those.
Several briefings for both the Historic Landmark and Planning Commission were held on the proposal
between February and May 2025, and the Planning Commission held two public hearings. (Planning’s staff
reports for the Planning Commission meetings that include changes to the proposal as it progressed can be
found at the following links: February 12, 2025 , March 12, 2025, and May 14, 2025.)
Numerous people spoke at the hearings and were about equally divided in support and opposition to the
proposal. Those who spoke in favor noted the ineffectiveness of current regulations, concerns about school
closures, low-quality housing, and the need for additional housing in the city. Comments in opposition
cited potential increased parking issues, loss of sunlight, and impact to solar power, changes to
neighborhood character, and decreased property values. Following the May 14, 2025 public hearing,
the Planning Commission voted unanimously forwarded a favorable recommendation to
the City Council.
Goal of the briefing: Review the proposed text amendment and determine if the Council supports
moving forward with the proposal.
POLICY QUESTIONS
1. In recent years the Council has approved a few housing related zoning amendments such as the
RMF-30 and Affordable Housing Incentives. The Council may wish to ask the administration how
those changes are being received and implemented by developers.
a. Some concerns have been raised about the potential for these recent zoning amendments to
encourage demolitions of existing housing stock, including naturally occurring affordable
housing. The Council may wish to ask the administration if the recently adopted zoning
amendments have resulted in more demolitions.
2. How do the proposed changes to RMF -35 and 45 align with the recently adopted RMF -30 zoning
district?
3. How do the proposed changes help advance the City’s adopted housing goals?
4. How does the proposal interplay with affordable housing incentives?
5. How do the proposed changes ensure new construction is compatible with the existing
development of neighborhoods throughout the city?
ADDITIONAL INFORMATION
In their current form, the two districts are nearly identical except for maximum building height . The
Administration’s initial proposal was to combine both districts into one RMF -45 district. Based on
feedback from the public and Planning Commission, the proposal was changed to keep the RMF -35 and
RMF-45 zoning districts separate and allow additional building types to be constructed on vacant lots and
as infill projects. Some additional recommended changes include reduced minimum lot sizes, eliminating
lot width minimums, upzoning approximately two dozen properties RMF -35 to RMF-45 (found in
attachment A to this report), and clarification of density bonuses. These are discussed below.
Page | 3
RMF-35 and RMF-45 zoning were adopted in 1995 and intended as a transition from low-density
neighborhoods to higher intensity areas. Adding multifamily developments to established neighborhoods
was also envisioned. However, Planning staff found single -family homes and large apartment buildings
have been the primary development patterns for the zones. Only 4% of lots in the districts have had any
new development, with a total of eight moderate -density projects in the last 30 years.
Planning identified the following complications with the current zoning districts:
• Minimum lot size requirements are too restrictive. Nearly half of lots in RMF -35 and 45 are smaller
than the required 5,000 square feet so new development is not possible. Multi -family buildings
cannot be constructed, and single -family homes are the only o ption.
• Minimum lot width requirements are too high. Only about one-third of properties in the RMF -35
and 45 zones meet the 50-foot minimum lot width. All others are too narrow.
• Parking requirements are too high. Planning found that approximately 96% of RMF -35 and 45
properties are within ¼ mile of a transit stop, yet the parking requirements are the same as single -
family zones. Affordability, density, and the viability of multifamily projects are impacted by
parking requirements that are too high.
Planning staff anticipates positive changes if the proposal is adopted, reducing minimum lot sizes and
allowing more housing options. These include adding accessory units and small -scale infill projects which
can supplement the property owner’s income and facilitate aging in place. An additional potential benefit is
reduced per capita water use due to more efficient use in moderate -density developments than single -
family building types.
The proposal is also intended to align with City plans including the Plan Salt Lake (2015), and Thriving in
Place and Housing SLC , both adopted in 2023.
PROPOSAL SUMMARY
Planning staff identified four key proposal objectives:
• Align the districts’ purpose with adopted plans and policies
• Clarify and simplify regulations
• Encourage moderate density development and infill development
• Preserve existing buildings and neighborhood character.
To achieve these objectives six recommendations are proposed:
• New “form-based” approach
• Adjustments to lot requirements
• Incentives for retention of existing structures
• Introduction of design standards
• New landscaping and open space requirements
• Updates to parking minimums
Each recommendation is summarized below. For additional information , please see pages 6-9 of the
Administration’s transmittal.
New “Form-Based” Approach
Rather than the current method of all residential building types being required to comply with the same
standards, the proposal calls for varying standards depending on building type. A multifamily building
impacts neighboring properties, the street, and n eighborhood differently than a cottage development,
rowhouses, and other less intense building types.
Page | 4
Under the proposal, sideways rowhouses and cottage courts would be added to the current list of building
types that includes single -family homes, duplexes, street-facing townhomes, and multi-family buildings.
Adjustments to Lot Requirements
Lot Widths
The proposal recommends eliminating the current minimum lot width , which varies depending on
use. Those would be replaced with a maximum lot width of 110 feet , intended to prevent the
banking of land for larger developments. As discussed above, only about one-third of RMF-35 and
45 lots meet the 50-foot minimum.
Lot Area
Current and proposed minimum lot areas for the subject zoning districts are shown in the table
below. The proposal would reduce the minimums for all but non -residential buildings.
Building Form Current Minimum Lot Area Proposed Minimum
Lot Area
Urban House
& Two-family
Single-family: 5,000 square feet
Two-family: 8,000 square feet
1,500 square feet
(for 1 or 2 units)
Cottage Development 5,000 square feet per unit, each
as a single-family dwelling
500 square feet per unit
Row House 3,000 square feet per unit 750 square feet per unit
(minimum of 3 units)
Multi-family 3 units: 9,000 square feet
RMF-35: +2,000 square feet
per unit over 3
RMF-45: +1,000 square feet
per unit over 3
750 square feet per unit
(minimum of 3 units)
Non-residential
building
5,000 square feet 5,000 square feet
Public Street Frontage
Proposed updates to the RMF-35 and 45 zoning districts would permit lots and buildings without
frontage on a public street if specific conditions are met. Current code requires street frontage for
all buildings unless an exception is approved by the Planning Commission.
Incentives for Retention of Existing Structures
The proposal calls for allowing bonus units if existing structures are retained. Similar incentives are offered
in the RMF-30 zoning district. If one or two dwelling units are kept, two bonus units would be allowed.
Retaining three or more units qualifies for four additional units. Note : this would not require the principal
building to be more than 50 years old, as is required in the zoning incentives for building preservation,
though the proposal allows for that.
Design Standards
Another proposed change is to add design standards to the RMF-35 and 45 zones. These are summarized
below and in the image that follows.
Page | 5
Durable Building Materials: a minimum of 50% of a building’s street-facing façade must use
durable materials such as stone, brick, wood siding, shingles, glass, etc.
Glass: Depending on building form, 15% to 20% of street-facing floors above the ground floor must
be glass.
Ground Floor Transparency: Again, depending on building form , 15% to 20% of street-facing
ground floors must be glass.
Entry Features: Under the proposal, entry features such as a porch and fence, terrace and light
well, portico, awning, forecourt, or stoop.
Building Fenestration: Street-facing walls cannot exceed a length of 15 feet without interruptions
that include windows, doors, or a change in the wall plane with an offset of at least 12 inches.

Landscaping and Open Space
Currently, the RMF-35 and 45 zones do not require open space other than yard setbacks. The proposal
recommends open space, landscaping, and personal and shared space that vary based on building forms , as
shown in the table below.
Building Form Open Space Per
Unit-Personal
Open Space Per
Unit-Common
Requirements
Urban House and
Two-family
N/A but subject to lot area
requirements. *
N/A but subject to lot area

Row House 200 square feet 150 square feet General landscaping
and proposed open
space standards
Multi-family Not permitted 50 square feet General landscaping
and proposed open
space standards
Other Building
Forms
Not permitted 15% of lot area General landscaping
and standards for
common open space.
*Open space for Urban houses and two -family dwellings
Urban house and two -family dwelling building forms would not be permitted to exceed 60% of the
lot area. Because these are smaller scale, the proposal does not call for personal or common open
space. They would still need to meet applicable landscaping requirements.
It is worth noting that the above open space requirements would not apply when a property is within 800
feet of a public park or open space.
Landscape Buffers
The proposal retains landscape buffers for row houses, multi -family, and non-residential building forms
currently found in City code. They would not be required for cottage developments, urban houses, or
single-family dwellings.
Parking
RMF-35 and 45 zoning are both currently in the “General” parking context, which has the highest
minimum parking requirements , with one to two parking spaces for each unit, depending on unit type or
number of bedrooms (more bedrooms require more parking). It is Planning’s opinion that this context is
appropriate for lower-density neighborhoods that are more car dependent and have limited transit access.
The proposal recommends including RMF-35 and 45 in the “Neighborhood Center” parking context which
requires only one parking space for all types and sizes of dwellings. Planning found that 20% of RMF -35
and 45 properties are within a quarter mile of a fixed rail station and, as n oted above, 96% are within a
Page | 7
quarter mile of a transit stop. Planning staff also recommends this change to encourage more bedrooms
within multifamily and rowhouse dwelling units . The current “General” parking context requires two
parking spaces for units with two or more bedrooms. The “Neighborhood Center” context would require
one space per dwelling unit regardless of the number of bedrooms.
ANALYSIS OF STANDARDS
Attachments D and E (pages 101-106) of the March 12, 2025 Planning Commission staff report outline
zoning text and map amendment standards that should be considered as the Council reviews this proposal.
The standards and findings from both attachments are combined and summarized below. Please see the
Planning Commission staff report for additional information.
Factor Finding
Whether a proposed amendment is consistent with the
purposes, goals, objectives, and policies of the city as
stated through its various adopted planning documents.
Complies
Whether a proposed amendment furthers the applicable
purpose statements of the zoning ordinance.
Complies
Whether a proposed amendment is consistent with the
purposes and provisions of any applicable overlay zoning
districts which may impose additional standards.
Complies. The proposal
is compatible with the
intent of the H
Historical Overlay
District.
The extent to which a proposed text amendment
implements best current, professional practices of urban
planning and design.
Complies
The impact that the proposed text amendment may have
on city resources necessary to carry out the provisions
and processes required by this title.
The adequacy of public facilities a services intended to
serve the subject property, including, but not limited to,
roadways, parks recreational facilities, police and fire
protection, schools, stormwater drainage systems, water
supplies, and wastewater an d refuse collection.
Proposed amendments
will not change the level
of impact that
development in the
affected districts may
have on City resources.
The impact that the proposed text amendment may have
on other properties that would be subject to the proposal
and properties adjacent to subject properties.
The extent to which a proposed map amendment will
affect adjacent and nearby properties due to the change
in development potential and allowed uses that do not
currently apply to the property.
Proposed amendments
will ensure that affected
properties have
equitable development
rights and protections
by ensuring that the
City’s multifamily
districts function as they
were initially intended.
The community benefits that would result from the
proposed text amendment, as identified in 21A.50.050.C.
While a community
benefit is not required,
the proposal will bring a
diversity of housing
options to
neighborhoods that have
Page | 8
typically excluded new
development since 1995.
The status of existing transportation facilities, any
planned changes to the transportation facilities, and the
impact that the proposed amendment may have on the
city’s ability, need, and timing of future transportation
improvements.
There are adequate
transportation facilities
to support the potential
additional growth from
the proposed
amendment.
The proximity of necessary amenities such as parks, open
space, schools, fresh food, entertainment, cultural
facilities, and the ability of current and future residents
to access these amenities without having to rely on a
personal vehicle.
RMF-35 and RMF-45
districts are, for the
most part, located
within neighborhoods
close enough to the listed
amenities for access
without reliance on
personal vehicles.
The potential impacts to public safety resources created
by the increase in development potential that may result
from the proposed amendment s.
No public safety
concerns were reported
during the department
review process.
Developments will be
reviewed for compliance
with building codes and
fire prevention
standards.
The potential for displacement of people who reside in
any housing that is within the boundary of the proposed
amendment and the plan offered by the petitioner to
mitigate displacement.
No more displacement
anticipated than current
regulations allow. A
citywide amendment
will help alleviate
displacement pressure
in vulnerable parts of
the city.
The potential for displacement of any business that is
located within the boundary of the proposed
amendment s and the plan offered by the petitioner to
mitigate displacement.
Proposed amendments
are not expected to
displace businesses or
change their status
under current zoning
regulations.
