Changing Property Use in San Francisco: A Guide to Converting Mixed-Use to Multifamily Residential
San Francisco, with its iconic skyline and vibrant neighborhoods, offers a unique landscape for property owners seeking to maximize their investment potential. For those looking at properties like 308 25th Ave, the opportunity to convert a mixed-use building into a fully residential, multifamily property can be both lucrative and complex. This guide will help you navigate the intricate web of zoning laws, permitting processes, and tenant considerations to ensure a successful transformation.
Understanding Zoning and Land Use Regulations
Zoning Designations
San Francisco's zoning regulations are designed to maintain the character and livability of its neighborhoods. The property at 308 25th Ave is zoned as "RM-1" (Residential Mixed, Low Density) and "NC-1" (Neighborhood Commercial, Cluster). While the RM-1 designation supports low-density multifamily dwellings, the NC-1 zoning allows for mixed uses, including commercial spaces. Transitioning to a fully residential property requires adherence to specific zoning guidelines.
Compliance with Density and Usage
The RM-1 zoning permits one dwelling unit per 800 square feet of lot area. For a 3,250 square foot lot, this equates to approximately four units "by-right." However, the existing six-unit configuration may be grandfathered due to legal non-conforming status. To expand beyond this, especially with the addition of Accessory Dwelling Units (ADUs), you'll need to engage with the Planning Commission, ensuring compliance with density, height, and bulk regulations.
Navigating the Change of Use Process
Filing for a Change of Use Permit
To convert your property from mixed-use to fully residential:
- Apply for a Change of Use Permit: This involves demonstrating compliance with RM-1 zoning requirements concerning density, setbacks, height, open space, and parking.
- Engage in Public Notification: Tenant-occupied buildings require public notice before changes. This is crucial for transparency and community engagement.
Adding Dwelling Units
While the RM-1 zoning limits unit numbers based on lot size, adding ADUs can increase your property’s density. State laws permit at least one ADU and potentially more, depending on existing structure conversions (basements, storage areas) and the addition of detached units.
Structural and Interior Work
Significant renovations, such as changing egress or removing structural elements, necessitate public and tenant notifications. Conditional use authorization may be required if these changes alter the building envelope or increase the unit count.
Tenant Notification and Protections
Complying with Section 311
Under Section 311 of the Planning Code, neighbors and tenants must be notified of changes that affect the building's use or unit count. This notification is crucial in tenant-occupied buildings to ensure compliance with San Francisco's robust tenant protection laws.
Managing Tenant Rights and Relocation
Tenant protection laws prohibit eviction solely for property conversion or renovation. Owners must provide adequate notice and possibly relocation assistance if the renovation impacts tenant habitability, particularly if "housing services" like parking or laundry are affected.
Key Regulatory Considerations
Density and Unit Maximums
- Baseline Density: RM-1 allows one unit per 800 sq ft, translating to four units "by-right" for a lot of 3,250 sq ft.
- ADU Allowances: Additional units can be added as ADUs, subject to state and local laws, without conforming to the baseline density.
Building and Safety Codes
New residential units must comply with fire safety, egress, electrical, plumbing, and accessibility codes. Major conversions may also trigger seismic retrofitting and energy compliance under Title 24.
Conclusion and Next Steps
Converting a mixed-use property into a residential multifamily dwelling in San Francisco is a strategic way to maximize rental income. By understanding zoning laws, engaging with the permitting process, and adhering to tenant protection regulations, property owners can navigate this transition smoothly.
Next Steps:
- Conduct a pre-application consultation with San Francisco Planning to review your proposal’s feasibility.
- Prepare and submit the necessary permit applications and tenant notifications.
- Develop a construction plan that minimizes tenant disruption and meets all building codes.
By approaching this process methodically and with due diligence, you can unlock the potential of your property and contribute positively to San Francisco’s housing landscape.
