How Do LA’s Property Development Regulatory Tools Really Work?
A Complete Guide to HESS, TOC, and Specific Plan Checkers
Los Angeles has one of the most complex real estate markets in the country. Developers face a maze of zoning rules, housing mandates, and local planning programs. If you’re planning to build in LA, understanding the city’s key regulatory tools is essential.
Recent years brought major changes through new state housing laws and local planning initiatives. Three property development regulatory tools now play a central role in how LA approves development projects:
Housing Element Site Selection (HESS)
Transit Oriented Communities (TOC)
Specific Plan Checkers
Each serves a different purpose but works together to shape growth, ensure compliance, and promote affordable housing.
What Is Housing Element Site Selection (HESS) and Why Does It Matter?
HESS is California’s core planning tool to meet housing targets. It stems from the Regional Housing Needs Allocation (RHNA) process, which assigns housing quotas to cities.
To comply with RHNA, LA must identify sites that could support thousands of housing units. HESS helps developers align with these targets by flagging qualifying parcels.
Key HESS Requirements and Criteria
To be eligible for HESS, a development site must meet several benchmarks:
Zoning and Density: Sites must be zoned for residential use with adequate density.
Infrastructure: Existing capacity for utilities like water and sewer is crucial.
Environmental Concerns: Sites with environmental constraints face added review.
Market Feasibility: The city checks whether development is economically realistic.
HESS Impact on Development Projects
| What Gets Checked | Importance | Time Added | Cost Added |
|---|---|---|---|
| Zoning Rules | Very Important | 2–4 months | $15,000–$50,000 |
| Infrastructure | Important | 6–12 months | $100,000–$500,000 |
| Environmental | Very Important | 4–8 months | $25,000–$200,000 |
| Market Analysis | Important | 1–3 months | $10,000–$30,000 |
Projects aligned with HESS may receive faster reviews and qualify for benefits under Senate Bill 9 and other housing legislation.
Understanding LA’s Transit Oriented Communities (TOC) Program
TOC is a local incentive program that encourages building near public transit. In exchange for adding affordable housing, developers get benefits like increased density and reduced parking requirements.
Incentives are based on a four-tier system tied to proximity to major transit hubs:
1st Tier: Best access, most benefits
Tier 2 & 3: Moderate access, moderate benefits
4th Tier: Basic access, minimal bonuses
TOC Tier Structure and Benefits
Tier 1 (Closest to transit)
Up to 80% density bonus
Reduced parking and increased height allowances
2-3 Tier (Medium access)
35%–70% density bonus
Moderate reductions in parking requirements
Tier 4 (Basic access)
35% density bonus
Minimal design and parking relief
TOC Affordable Housing Requirements
| Tier | Required % of Affordable Units | Income Target | Compliance Options |
|---|---|---|---|
| 1st Tier | 11% | Very Low Income | In-lieu fee possible |
| 2nd Tier | 8% | Low Income | Off-site development allowed |
| 3rd Tier | 6% | Moderate Income | Land dedication possible |
| 4th Tier | 5% | Moderate Income | Mix-and-match strategies |
Note: When TOC guidelines conflict with a specific plan, the specific plan takes precedence.
Navigating Specific Plan Checkers in LA
Specific plans govern smaller geographic areas in LA with more detailed zoning rules. They protect neighborhood character while guiding growth.
Each plan sets its own standards for:
Building height
Setbacks
Parking
Design and materials
Affordable housing and public space
Major LA Specific Plans and Their Focus Areas
Hollywood: Encourages density near transit while preserving entertainment uses and historic character
Downtown LA: Focuses on mixed-use, high-density growth with minimal parking requirements
Venice: Prioritizes coastal protection and affordable housing
West LA: Maintains strict height limits and single-family zoning integrity
Specific Plan Compliance Process
Initial Review: Focus on zoning, height, setbacks
Design Review: Aesthetic compliance, architectural quality
Community Input: Neighborhood outreach and feedback
Final Coordination: Inter-agency sign-offs from Planning, Building & Safety, etc.
Case Study: TOC + Specific Plan Success in Hollywood
Project Overview
A 150-unit mixed-use development in a Tier 2 TOC area leveraged all three tools:
70% density bonus
50% parking reduction
Height increase from 45 ft to 75 ft
The HESS-aligned site = expedited review
Hollywood Plan compliance = smooth design approvals
Timeline:
Approval in 18 months (vs. typical 36)
Construction started in 24 months
Financial Upside:
$8M+ gain from density & parking bonuses
$2M saved in carrying costs

Practical Implementation Guide
Step-by-Step Development Process
1st Phase: Initial Assessment (Months 1–2)
Analyze site, TOC eligibility, HESS status, specific plan rules
2nd Phase: Strategy Development (Months 2–3)
Build integrated plan, assemble team, prepare cost projections
3rd Phase: Application Preparation (Months 3–6)
Submit documentation, finalize design, engage community
4th Phase: Review and Approval (Months 6–18)
Coordinate revisions, respond to feedback, secure permits

Frequently Asked Questions on Property Development Regulatory Tools
How long does it typically take to navigate all three regulatory tools for a major development project?
Timelines vary. A well-prepared project using HESS, TOC, and specific plan approvals generally takes 12–18 months for regulatory clearance. Complex or controversial projects may take 24–36 months. Early preparation and coordinated submissions can significantly shorten the process.
Can a project qualify for TOC incentives while also being on the HESS inventory?
Yes—and this combination can be especially powerful. HESS designation often enables expedited reviews, while TOC incentives provide generous development bonuses. However, affordable housing requirements must be carefully aligned to avoid conflicts.
What happens when TOC guidelines conflict with specific plan requirements?
Specific plans take precedence. Courts have confirmed that specific plan rules override conflicting TOC provisions. Developers should work closely with city staff early in the process to find compliant design solutions that meet both frameworks.
Are there any upcoming changes to these regulatory tools that developers should know about?
Yes. California continues to introduce new housing bills that streamline processes and expand incentives. LA also updates TOC and specific plans based on performance reviews and community input. Ongoing monitoring of legislation and city planning updates is essential.
How much should developers budget for professional consultant fees when using these tools?
Expect to budget $100,000–$300,000 for land use attorneys, planners, architects, and technical specialists. These costs typically represent 2–4% of a total project budget—and can often be recouped through faster approvals and higher development yields.
What are the most common mistakes developers make when using these regulatory tools?
The biggest mistake is treating each tool in isolation. Sequential navigation creates delays and missed optimization opportunities. Others include poor community engagement, weak site analysis, and underestimating compliance costs. The most successful developers invest early in planning and realistic timelines.
