Zoning administrator approves 299‑unit mixed‑use building at 425 Humboldt in downtown Santa Rosa

The Santa Rosa zoning administrator approved a design review permit on March 20, 2025, for a seven‑story mixed‑use building at 625–631–635 Fifth Street and 431 Humboldt Street (project file DR24‑056), clearing the way for a 299‑unit residential development with ground‑floor live/work and retail space.

The project — described by city staff as a 7‑story building with a proposed floor‑area ratio of 4.69, which the staff said meets the downtown midpoint FAR policy — was recommended for approval by the Planning and Economic Development Department after review under CEQA exemptions cited by staff. "The proposed project is at 4.69, which meets our midpoint FAR," said Kim of the Planning and Economic Development Department during the staff presentation.

The zoning administrator’s approval came after a presentation by the applicant team and public comment; at the end of the hearing the zoning administrator said, "With that, I approve the project." The action is final unless appealed to the city clerk within 10 calendar days, the clerk’s office notice at the meeting said. The transcript recorded some uncertainty about the calendar‑date deadline because of a city holiday and said the city listed Tuesday, April 1, 2025, as the deadline in its reading of the appeal instructions.

Why it matters

The project is an infill, transit‑adjacent development in downtown Santa Rosa intended to add housing and ground‑floor activity to a central part of the city. The developer and architects emphasized walkability and downtown activation; staff framed the proposal as consistent with the General Plan and downtown policy and cited CEQA exemptions that applied to the review.

What was approved and why

Staff said the proposal is a seven‑story, "5 over 2" mixed‑use building that would include 299 residential units, live/work units on the lower floors and retail at a corner, with resident amenities and multiple courtyards. The Planning and Economic Development Department recommended approval and identified two CEQA exemptions in the record: a statutory exemption (transcript cited "15182") and the categorical infill exemption (transcript cited "15332"). The staff report used the project file number DR24‑056.

Developer and design team details

Harold Robinson, president of IGH Partners, described a project that was originally entitled at a smaller scale before the pandemic and later expanded to 299 units. Martin Ball of CCBG Architects described the building massing, site orientation (Fifth Street frontage, Humboldt frontage, and Riley Street), the interior courtyard configuration and the intent to provide multiple storefronts and points of entry to activate the street. Brianna Morrison of Carlisle Macy explained landscaping and courtyards and described limitations to adding street trees on the Riley frontage because of underground utilities.

Parking, transportation and amenities

The applicant said parking will be "unbundled." "Residents will have two choices," Harold Robinson said, explaining that roughly 0.6 parking spaces are expected per unit and that the project team will pay for additional off‑site parking in the nearby Fifth Street Garage so residents can access parking without it being included in every lease. The team also said the city will provide a bus pass for each resident as part of an arrangement discussed in the hearing.

The design includes resident amenities: a two‑story lobby, a co‑work/meeting space, a fitness room on Level 2, a sky deck and party room on Level 7, dog wash, and a bicycle storage and fix‑it station. The applicant said live/work units and retail space are intended to bring foot traffic to the Humboldt and Fifth Street frontages.

Public comment and design review input

The staff summary and applicant presentation noted broad public support from downtown businesses and housing advocates, including emailed support cited in the record from D.D. Swanheiser and James Lloyd of the California Housing Defense Fund. Objections recorded in the staff summary focused on parking adequacy, construction noise and privacy/overshadowing for adjacent properties. Staff responded during the hearing that the site is within the downtown station area where the city’s policies do not impose a minimum parking requirement.

The project was previously presented to the Design Review Board (DRB) in January. DRB input noted in the hearing included requests for additional street trees and for adjustments to the building’s color palette; the applicant said the original "salmon" color was toned down to a more muted coppery tan. Design review board representative Sharon praised the applicant for responding to DRB comments and for adding street trees on Humboldt and other refinements.

A specific condition raised at the hearing asked the applicant to "explore alternative ground treatments" where the current landscape plan shows artificial turf on a courtyard deck; the zoning administrator’s approval included that language in the meeting record after discussion among staff, the DRB representative and the applicant. As landscape designer Brianna Morrison said of the courtyard surfacing, the team intended to use soft elements "in a very constrained, thoughtful, specific location."

Timing, outstanding conditions and implementation risks

The applicant and construction manager said a typical schedule for a project of this size is about 24 months of construction. The team said they aim to start in 2025 and finish in roughly two years but noted potential delays tied to supply‑chain uncertainty and to utility work. The applicant identified PG&E coordination as a specific preconstruction dependency because overhead and underground utility locations affect allowed equipment and staging; the applicant said a PG&E clearance is one of the last pieces needed to confirm a construction start date.

Formal action and appeal

The zoning administrator approved a design review permit by resolution for the 425 Humboldt apartment project (file DR24‑056). The meeting record states the decision is final unless an appeal is filed in the city clerk’s office within 10 calendar days; the city official reading the appeal instructions cited Tuesday, April 1, 2025, in the meeting but the transcript shows confusion about the holiday and whether the deadline bumps to the next business day. The approval was recorded without a roll‑call vote count in the public hearing transcript.

Looking ahead

If permits and PG&E coordination proceed on the applicant’s timeline, site work could start later in 2025; the applicant emphasized it will continue to refine materials, landscaping and the inclusionary housing mix as it proceeds through the building permit and construction phases. The transcript records the applicant saying they expect to increase the number of inclusionary units above the five initially planned and that they are working through the city fee and inclusionary schedules to determine a final count.
