Survey lot lines, identify setbacks, check utility locations, confirm zoning eligibility for ADU placement.
Conceptual Design
Draft floor plans, elevation studies, and site plan showing placement relative to existing home and property lines.
Preliminary Permitting Review
Identify permit requirements, fees, and approvals needed from City of Folsom before final design.
Why Local Expertise Matters
Building in Folsom requires knowledge of local zoning, permit systems, and neighborhood standards. Mistakes cost time and money.
Folsom Zoning & Setback Rules
Folsom's zoning code defines what you can build. ADUs require minimum 4-foot rear and side setbacks. Height limits vary by zone—detached ADUs are typically 16 feet, attached units can reach 25 feet. Knowing these constraints upfront saves design revisions.
Most Folsom residential zones allow ADUs. Check your specific zone's density, height, and parking rules before committing to a design.
eTRAKiT & Digital Permitting
Folsom uses eTRAKiT and ProjectDox for permit submissions. Applications must be complete and accurate. Missing documents cause delays. We prepare submissions that pass intake review on the first attempt.
School District Impact Fees
New construction in Folsom triggers school district development impact fees. The Building Division requires a CD-B103 form completed by both city and school district before permit issuance. We handle this coordination.
30+ years of custom home experience across 500+ projects. We know Folsom's neighborhoods, building officials, and inspection patterns.

Frequently Asked Questions
Can I build a custom home in any Folsom neighborhood?
Most Folsom neighborhoods allow new construction on buildable lots, but zoning rules vary. Downtown areas have design review and height restrictions. American River Canyon has view-plane and habitat overlay rules. North Folsom has standard residential zones with fewer constraints. Check your specific lot's zoning district before purchasing.
Do HOA rules override city zoning for ADU projects?
No. City zoning is the baseline—your property must comply with Folsom code first. If your HOA is stricter, you must meet both HOA and city standards. Some homeowners associations restrict ADU size, placement, or rental use. Review your CC&Rs before design starts.
What permits are required for a new custom home in Folsom?
Building permits, plan review, and city inspection approvals are mandatory. School district development impact assessments are required before permit issuance. Tree removal permits apply if protected trees are on site. Regional sanitation approval is needed for some projects. Folsom Building Division handles permit coordination through the eTRAKiT system.
Are there special rules for ADUs near Folsom Lake or riverfront?
Yes. Properties near water features may have setback increases, habitat conservation restrictions, or grading limitations. Folsom's design review and environmental compliance add review steps. Floodplain properties require additional engineering and FEMA coordination. Early site analysis avoids costly design changes later.
Can I rent my ADU right away after it's finished?
Yes, once the Certificate of Occupancy is issued. Folsom allows long-term rentals (30+ days minimum) with no owner-occupancy requirement. Short-term rentals are not permitted. Rental terms and any HOA rental restrictions should be reviewed before construction begins.
Does my property need to be a certain size for an ADU?
No. California state law requires no minimum lot size for ADUs. Folsom adheres to this rule. Your lot just needs enough space to meet setback requirements (4 feet minimum from rear and side lines) and fit the ADU footprint plus any required parking.
