Summary

San Luis Obispo County implements California's density bonus law through Section 22.12.020, letting a qualifying housing project of five or more units add density, parking concessions and other incentives above the base maximum set by Planning Area Standards. Applicants must document eligibility under both the state and county density bonus codes, and state law controls whenever it conflicts with the county's version.

These county ordinances apply to unincorporated areas of San Luis Obispo County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

An application that satisfies the requirements of this section and State Density Bonus Law for a qualifying housing project may be eligible to receive a density bonus and other incentives, such as concessions and adjusted parking ratios. A housing project approved to receive a density bonus may establish additional housing units over the standard maximum residential density allowed by ordinance, including the standard maximum residential density set by Planning Area Standards... Application Submittal Requirements... The development project shall have five or more dwelling units, exclusive of any density bonus units.

Full Breakdown

12 gives San Luis Obispo County two separate density incentive tracks. 010 is the county's own Regional Housing Incentives program, letting a multi-family project inside an Urban Reserve Line earn incentive points, two points per very-low-income unit built on site, that unlock additional density and reduced standards. , referred to in the code as State Density Bonus Law. A project that includes deed-restricted units for very low, lower, or moderate income households, transitional foster youth, disabled veterans, homeless persons, senior citizens, or a mixed-use component can be approved for a density bonus, plus incentives such as concessions and adjusted parking ratios, over and above the standard maximum residential density otherwise allowed by ordinance or by Planning Area Standards.

Subsection A states plainly that where the county's chapter conflicts with State Density Bonus Law, the state law prevails. To apply, a project must have five or more dwelling units before counting any bonus units, and the level of permit review required is the same as for a non-bonus project of that type, though CEQA review must still account for the bonus units. Applicants must include citations of the state and county density bonus code sections in their submittal package, along with documentation required by the county's Density Bonus Guide. 020 bonus is applied on top.

Violations & Fines

There is no penalty provision here since this is an entitlement program, not a prohibition. A project granted density-bonus units that fails to record the required affordable housing agreements under Section 22.12.030, or fails to maintain deed-restricted units as promised, can have its bonus approval revoked and be required to bring the project back into compliance with standard density limits through code enforcement.

Frequently Asked Questions

Can I get a density bonus with fewer than five units?
No. Section 22.12.020.B.1 requires the development project to have five or more dwelling units, not counting any bonus units, before an application can request a density bonus, adjusted parking ratios, incentives, concessions, or waivers of development standards.
Does county law or state law control if they conflict?
State Density Bonus Law controls. Section 22.12.020.A states that where there is a conflict between California Government Code Section 65915 et seq. and the county's density bonus ordinance, the State Density Bonus Law prevails over the county's chapter.
Can I combine the county's own incentive program with the state density bonus?
Yes. Section 22.12.010 Regional Housing Incentives is a separate county program available within an Urban Reserve Line, and any density increase it grants is calculated into the base density before a Section 22.12.020 state density bonus is layered on top.
