Folsom, CA Zoning Overlays & Bonuses: Downtown Design Guide (2026)

FMC 17.52.120(B) directs the seven-member historic district commission to "develop and recommend design guidelines to the city council for the historic district," guidelines the city council then adopts by resolution under FMC 17.52.400(B) and that govern review going forward. FMC 17.52.300(A) sends the largest category of projects, including all new office, industrial, commercial, and residential buildings and any addition exceeding 25 percent of existing square footage or 500 square feet, to the full commission for review; smaller exterior remodels and new accessory buildings go to the community development director instead under 17.52.300(B).

Minor work such as like-for-like roofing and window replacement, exterior color changes on houses, small patio covers, and solar panels is exempt from review entirely under 17.52.300(C), unless the property sits on the city's cultural resources inventory. FMC 17.52.330 lists the review criteria: compliance with the general plan and zoning, conformance with city-wide design guidelines and the historic district's own design and development guidelines, conformance with any project-specific standards from a planned development permit, and compatibility of materials, textures, and colors with the surrounding neighborhood.

Design review approvals lapse after two years unless a building permit application is filed, per FMC 17.52.350, though a one-year extension is available for a fee. Director-level approvals can be elevated to the full commission either at the director's discretion or on an applicant's request and fee payment, and appeals of commission or director decisions run through FMC 17.52.700.
