Kolmo has launched a free online database that helps homeowners find verified permit rules across 80 jurisdictions in Washington state. Available through kolmo.io/permits, the AI-powered service covers cities and agencies in King, Pierce, and Snohomish counties.
The tool contains 457 verified rules and links each one to its official municipal source. It is designed to reduce the time residents spend searching city websites, reading long PDF files, or relying on incomplete search results.
Permit Information in One Searchable Place
Local permit requirements often vary by city, county, and project type. A homeowner replacing a roof may face different rules from someone building a deck, converting a garage, or adding a backyard structure.
Those differences can be difficult to track. Municipal guidance may appear across planning pages, building department documents, zoning codes, and downloadable forms. Rules can also change after local governments update their codes.
Kolmo’s database brings selected requirements into a single public resource. The site is un-gated, meaning users do not need to submit contact details or create an account before searching.
The service highlights three main features:
- Coverage of 457 verified permit rules.
- Information from 80 jurisdictions across three counties.
- Direct links to city source pages and exact official wording.
Source Links Offer a Check on AI
The direct citations are an important part of the service. AI tools can summarize public information quickly, but summaries may omit exceptions or misread technical language.
Kolmo addresses that concern by connecting each listed rule to a specific government page. Users can compare the database entry with the municipality’s exact wording before making a decision.
The service is designed to answer questions that often send homeowners into “a spiral of municipal PDFs.”
That approach may help users avoid rough guesses based on general web searches. Search engines can surface outdated city pages, third-party articles, or rules from a neighboring jurisdiction. A cited database gives homeowners a clearer path back to the responsible public agency.
Coverage Has Practical Limits
The database’s geographic reach is broad but not statewide. Its current coverage is limited to jurisdictions in King, Pierce, and Snohomish counties. Residents elsewhere in Washington will still need to consult their local planning or building departments.
The listed total also does not mean every possible permit question is covered. Local codes can include special rules tied to shoreline areas, flood zones, historic districts, steep slopes, utilities, and property-specific conditions.
Permit guidance may also differ from final approval. City staff can require plans, inspections, engineering documents, or added reviews based on a project’s location and design.
For those reasons, the database is best viewed as a research and planning tool rather than a substitute for an official permit decision. Homeowners should follow the linked source, confirm that the guidance is current, and contact the relevant agency before beginning work.
Potential Impact for Homeowners and Cities
Faster access to permit information could help residents estimate costs and schedules earlier. It may also reduce basic inquiries to municipal staff, allowing departments to focus on applications and complex code questions.
The next test will be how consistently Kolmo updates its 457 verified rules as cities revise their requirements. Accuracy, update timing, and wider geographic coverage will shape the tool’s long-term value.
For now, the database offers homeowners in three populous Washington counties a simpler starting point. Its strongest feature is not AI alone, but the ability to trace an answer back to official language.
