Sacramento County Infill Program 2026: What Developers Need to Know
The Sacramento County Infill Program 2026 is focused on making it easier to build housing and reinvest in established commercial corridors and other suitable infill locations across unincorporated Sacramento County.
The County’s current infill work is designed to remove policy barriers, encourage redevelopment, and create more livable, walkable neighborhoods. The effort grew from discussions about development barriers, including a 2024 Board of Supervisors workshop and a subsequent Housing and Infill Resolution of Intention.
For property owners, builders, housing developers, and community members, the most important point is that 2026 is an active policy-development year. Several proposed zoning changes are moving through the County’s review process rather than all of the proposed rules already being final requirements.
That distinction matters when evaluating a property or planning a project.
What Is the Sacramento County Infill Program?
Sacramento County describes its Infill Program as an effort to remove policy barriers that can hinder development along commercial corridors. The broader objective is to attract investment while supporting neighborhoods that are more livable and walkable.
The program is not simply a single grant or construction subsidy. Instead, it involves a combination of:
- Zoning changes
- Development-standard revisions
- Housing-production strategies
- Commercial-corridor improvements
- Affordable housing incentives
- Potential financial tools
- Streamlined development processes
- Adaptive reuse opportunities
The County’s 2024 Infill Program Update identified barriers to infill development and actions that could help address them. The County’s current Housing and Infill Zoning Code Amendment builds on that policy direction.
Sacramento County Infill Program 2026 Status
One of the most important developments for 2026 is the Housing and Infill Zoning Code Amendment.
According to Sacramento County, the proposal includes changes affecting multifamily housing, commercial corridors, adaptive reuse, neighborhood-scale multiunit buildings, and development administration. One proposed change would eliminate use-permit requirements for multifamily development.
The County’s published 2026 schedule lists:
| Project stage | Published timeframe |
|---|---|
| Project analysis | November 2025 – March 2026 |
| Internal drafting | March – May 2026 |
| Stakeholder review | May – June 2026 |
| Public outreach and hearings | June – August 2026 |
| Planning Commission hearing | September 2026 |
| Board of Supervisors hearing | November 2026 |
| Post-adoption implementation | December 2026 |
These are estimated timeframes, so developers should verify the latest County information before relying on a proposed change for a project decision.
Major 2026 Housing and Zoning Changes
1. Multifamily Development Standards
The proposed amendment would revise development and design standards for multifamily housing throughout the County, including additional considerations for commercial corridors and adaptive reuse.
This could be significant for developers evaluating underused properties where existing development standards make additional housing difficult to achieve.
2. Neighborhood-Scale Multiunit Housing
Another proposed change would allow neighborhood-scale multiunit buildings, including triplexes and fourplexes, in certain single-family residential zoning districts.
This represents an important shift in how smaller-scale housing could fit into established residential neighborhoods if the proposed provisions are adopted.
3. Multifamily Use-Permit Changes
Sacramento County is proposing to eliminate use-permit requirements for multifamily development.
The goal is to reduce procedural barriers and make housing production more predictable. However, eliminating a use permit does not mean that every multifamily proposal automatically qualifies for approval. Other zoning, design, environmental, infrastructure, and building requirements can still apply.
4. Commercial Corridor Infill
Commercial corridors are a major focus of the County’s infill strategy.
The concept is straightforward: instead of relying entirely on outward expansion, communities can make better use of already-developed areas by encouraging housing, mixed-use projects, redevelopment, and reinvestment in established corridors.
The proposed 2026 zoning work includes a Commercial Corridor Overlay as part of the draft amendments.
5. Adaptive Reuse
Adaptive reuse can turn an existing building or property into a new use rather than requiring an entirely new development site.
Sacramento County’s proposed Housing and Infill Zoning Code Amendment specifically includes development and design considerations for adaptive reuse.
This approach can be particularly useful where older commercial properties have underused space but remain connected to existing roads, utilities, and neighborhood services.
Sacramento County Housing Incentives for Infill Development
Infill development can benefit from more than zoning flexibility. Affordable housing projects may qualify for specific incentives under Sacramento County programs.
The County’s Housing Element programs identify an Affordable Housing Fee Deferral program for qualifying affordable housing projects. The County, Sacramento Area Sewer District, Sacramento Regional County Sanitation District, and Sacramento County Water Agency each have fee-deferral opportunities subject to applicable requirements.
Another important tool is the Affordable Housing Incentive Program, which incorporates California Density Bonus Law.
Eligible developments may receive benefits such as:
- Increased allowable density
- Incentives or concessions from certain development standards
- Waivers of development standards under qualifying circumstances
- Other benefits provided under applicable law
The County states that eligible applications can be processed concurrently with other required planning entitlements and that there is no additional County fee for processing an eligible Affordable Housing Incentive Program application.
Affordable Housing Density Bonus in Sacramento County
The Affordable Housing Incentive Program is particularly important for developers considering projects with income-restricted units.
Current County zoning provisions establish eligibility requirements for housing developments of five or more units. Depending on the project and affordability structure, qualifying categories can include low-income housing, very-low-income housing, senior housing, certain moderate-income for-sale housing, and projects in which all qualifying units are income restricted.
The County’s zoning code also contains density-bonus calculations and rules concerning incentives, concessions, and waivers.
Importantly, these benefits are not automatic for every housing project. Eligibility depends on the project’s characteristics, affordability commitments, location, applicable zoning provisions, and other requirements.
A New 2026 Density-Bonus Provision
The County’s current zoning-code library shows a provision added in June 2026 establishing an additional density-bonus chart for certain affordable-unit percentages.
For example, the published table provides different potential density increases depending on the percentage of additional affordable units and the applicable income category. The same section states that an applicant seeking a density bonus and incentives or waivers must submit an application to Planning and Environmental Review.
Because these rules can be highly project-specific, developers should review the current version of the zoning code rather than relying on an older density-bonus chart.
Development Impact Fee Relief for Affordable Housing
Another notable 2026 development is Sacramento County’s expansion of its Three-Year Development Impact Fee Offset Pilot Program.
In August 2026, the County announced that the Board of Supervisors approved an expansion allowing eligible affordable housing projects to receive offsets for development impact fees associated with three separate parks districts.
Eligible projects can receive up to $10,000 per affordable housing unit in fee offsets, subject to the program’s requirements. The County reported that four affordable housing projects totaling 435 units had already received approval for approximately $2.16 million in offsets.
This is particularly relevant because development fees can materially affect the financial feasibility of affordable housing.
Green Means Go Funding and Sacramento County Infill Housing
Regional funding can also complement Sacramento County’s infill strategy.
In January 2026, SACOG announced a Green Means Go Health Net funding round supporting affordable or permanent supportive housing. The program offers up to $1.8 million for a single catalytic housing project located in an adopted Green Zone within Sacramento County or eligible local jurisdictions.
The stated priority is accelerating infill residential development while improving housing affordability, with consideration given to factors such as unit production, deed-restricted affordable units, and depth of affordability.
This type of funding should be viewed separately from Sacramento County’s zoning amendments because eligibility, application requirements, funding availability, and selection criteria can differ.
Sacramento County Affordable Housing Ordinance
Developers should also distinguish the Infill Program from the County’s Affordable Housing Ordinance.
The County’s Affordable Housing Ordinance establishes requirements involving affordable housing contributions, which can include an affordability fee, land dedication, and/or affordable units depending on the circumstances of the development.
As of March 27, 2026, Sacramento County lists the affordability fee at $3.91 per habitable square foot of each housing unit.
Therefore, a developer evaluating an infill project should consider both potential incentives and applicable obligations.
Who Can Benefit From Sacramento County Infill Policies?
The policies may be relevant to several groups.
Property Owners
Owners of vacant, underused, or commercially located properties may want to determine whether proposed zoning changes could improve redevelopment potential.
Housing Developers
Developers can evaluate whether updated multifamily standards, density incentives, affordable housing programs, or fee assistance could improve project feasibility.
Affordable Housing Organizations
Nonprofit and affordable housing developers may find the County’s fee deferrals, density incentives, fee offsets, and regional funding programs particularly relevant.
Small-Scale Builders
Proposed neighborhood-scale housing changes could create additional opportunities for smaller residential projects, subject to the final zoning rules and site-specific requirements.
Community Members
Residents can follow the County’s public hearings and community meetings to understand how proposed housing and commercial-corridor changes could affect their neighborhoods.
How to Evaluate an Infill Property in Sacramento County
A strong infill opportunity is not determined by the property’s address alone.
Before purchasing land or committing substantial design costs, examine the following:
1. Current zoning
Determine the property’s existing zoning designation and permitted uses.
2. Proposed zoning changes
Check whether the property could be affected by the Housing and Infill Zoning Code Amendment or another zoning update.
3. Housing Element status
Review whether the property is identified in an applicable Housing Element inventory or program.
4. Development standards
Evaluate density, setbacks, height, parking, landscaping, access, design requirements, and other applicable standards.
5. Affordable housing eligibility
If the project includes qualifying affordable units, determine whether density bonuses, incentives, concessions, waivers, or fee programs could apply.
6. Infrastructure
Review water, sewer, drainage, transportation, utilities, and other infrastructure requirements.
7. Environmental requirements
Determine what level of environmental review or exemption may apply.
8. Financial feasibility
Estimate land costs, construction costs, fees, financing, affordability requirements, and potential incentives before assuming a project will be profitable.
Sacramento County Infill Program vs. Affordable Housing Incentive Program
These terms are related but should not be treated as identical.
| Feature | Infill Program | Affordable Housing Incentive Program |
|---|---|---|
| Primary purpose | Reduce barriers to infill development | Encourage qualifying affordable housing |
| Main focus | Zoning, corridors, development policy | Density, incentives, concessions and waivers |
| Applies to every project? | Not necessarily | No; eligibility requirements apply |
| Affordable units required? | Not universally | Generally tied to qualifying affordability categories |
| Density bonus | May interact with broader zoning policy | Central program feature |
| Fee assistance | May involve broader policy tools | Separate fee programs may apply |
The County’s current infill initiative is broader than a single financial incentive program.
What Developers Should Watch in Late 2026
The most important issue is the transition from proposed policy to adopted regulation.
Sacramento County’s published schedule places a Planning Commission hearing in September 2026 and a Board of Supervisors hearing in November 2026, followed by estimated implementation in December 2026.
Until final adoption and implementation, developers should avoid treating proposed language as guaranteed development rights.
A property that appears attractive under a draft amendment could ultimately be subject to modified standards after public review.
Common Mistakes to Avoid
Assuming “Infill” Means Automatic Approval
Infill designation or location does not eliminate every regulatory requirement.
Using an Old Zoning Code
Development regulations can change. Always verify the current County code before making a major investment decision.
Ignoring Affordable Housing Obligations
Potential incentives should be evaluated alongside applicable affordability requirements and fees.
Treating Proposed Amendments as Final
Draft regulations can change during public hearings.
Looking Only at Density
A project’s financial feasibility can also depend on parking, infrastructure, construction costs, utility capacity, design requirements, financing, and environmental considerations.
Missing Funding Deadlines
Programs such as competitive regional funding may have separate application windows and eligibility standards.
Sacramento County Infill Program 2026: Key Takeaways
The 2026 Sacramento County infill landscape is evolving quickly.
The County is pursuing zoning and policy changes intended to accelerate housing production and redevelopment, particularly in commercial corridors and established communities. Proposed changes include multifamily development revisions, neighborhood-scale multiunit housing, adaptive reuse provisions, commercial-corridor tools, and elimination of certain multifamily use-permit requirements.
At the same time, affordable housing developers may have access to several complementary tools, including density bonuses, development-fee assistance, fee deferrals, and regional funding opportunities.
For anyone considering an infill project, the smartest approach is to evaluate zoning + Housing Element status + development standards + affordability programs + fees + infrastructure + financing together.
Frequently Asked Questions

Final Word
The Sacramento County Infill Program 2026 represents a broader effort to make established areas more capable of supporting new housing and reinvestment.
The biggest opportunities may come from the combination of updated zoning rules and targeted housing incentives rather than from any single program. Developers who understand the interaction between zoning, density, affordability, fees, infrastructure, and approval procedures will be better positioned to evaluate potential projects.
Because several 2026 changes are still moving through the County’s legislative process, the safest strategy is to verify the latest adopted zoning code, project documents, hearing results, and program requirements before making a purchase, submitting plans, or calculating expected development rights.
