What it does
Placentia Adu is an agent skill from mikeOnBreeze/cc-crossbeam. City-level ADU regulations for Placentia, California. This skill should be used when answering ADU questions specific to Placentia — local ordinance provisions, development standards, permit process, fees, fire requirements, zoning, and anything that differs from or adds to California state ADU law. This skill layers on top of the california-adu state law skill. Load state law first, then use this skill for Placentia-specific requirements.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including reference files (for example `CLAUDE.md`, `references/building-codes.md` and `references/context-housing-sb9.md`).
The repository describes itself as: CrossBeam Permits — AI-assisted building-permit plan review for cities and builders. The licence is MIT.
When your agent uses it
- Placentia-specific requirements
Example prompts
- “/placentia-adu”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cc5591e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
ci-placentia-ca.smartgovcommunity.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Placentia Adu loads about 1.7k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 114 tokens; SKILL.md has 739 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Placentia ADU — City Regulatory Skill
This skill contains Placentia's city-level ADU rules — the local ordinance, development standards, permit process, fees, and fire/zoning requirements that supplement or override California state ADU law.
How this skill relates to state law: The california-adu skill covers the state floor (Gov. Code §§ 66310-66342). This skill covers what Placentia adds, matches, or potentially conflicts with. Always load state law context first, then layer this skill on top for city-specific questions.
What this covers: Placentia Municipal Code Chapter 23.73, Title 20 building codes, Title 23 zoning, Title 18 fire code, permit process, fees, and local development standards.
What this does NOT cover: State-level ADU law (use california-adu skill), federal requirements, or project-specific engineering.
Decision Tree Router
STEP 1: What's the Question About?
| Topic | Load These References |
|---|---|
| ADU height, setbacks, size, building separation, or units allowed | ordinance-adu-standards.md |
| Parking requirements or exemptions | ordinance-adu-standards.md, transit-parking.md |
| Design standards, entrance visibility, stairway rules | ordinance-adu-standards.md |
| JADU rules, owner occupancy, deed restrictions, sale/rental | ordinance-adu-rules.md |
| Impact fees, school fees, fee exemptions | fees-impacts.md |
| Fire sprinklers, fire plan review, fire hazard zones | fire-placentia.md |
| Which building codes apply, local amendments, 2025 code cycle | building-codes.md |
| Zoning zones, lot coverage, base setbacks | zoning-residential.md |
| Permit process, submittal, who to contact, inspections | permit-process.md |
| Utilities, drainage, grading, stormwater, WQMP | utilities-grading.md |
| Energy code, insulation, solar PV | energy-climate.md |
| Transit stops, Metrolink, TOD district, parking exemption zones | transit-parking.md |
| Housing policy, RHNA, SB 9, pre-approved plans | context-housing-sb9.md |
STEP 2: Does a State Law Conflict Apply?
If the question involves any of these topics, also load hcd-compliance.md:
- Owner occupancy enforcement
- Building separation requirements
- Entrance or stairway visibility restrictions
- HCD findings or state preemption
- Potential conflicts between local ordinance and state law
Key principle: Where Placentia's ordinance is more restrictive than state law, state law preempts. The hcd-compliance.md file identifies the known issue areas. Placentia's code includes an explicit preemption clause: "If there is any inconsistency between this chapter and mandatory requirements of state law, state law shall control."
STEP 3: Need More Information?
Every reference file includes URLs to city websites, ecode360, and external resources. If a question requires information beyond what's in the reference files, use these URLs with web search or browser tools to find the answer.
