How to use the property lists.

Three counts, with the same meaning in every city

Available properties counts the property addresses we can show from public inventories and permit records. This is coverage, not a count of owners needing work.

Possible opportunities have evidence of residential use and older completed work in your selected trade, with no open job or conflicting record found. These are reasons to check a property, not confirmed demand.

Needs review includes missing work history, recent replacements, open jobs and unclear records. These properties remain searchable, but do not qualify as possible opportunities.

Available properties includes both categories. Every city uses the same rules. Selecting “All available properties” or “Needs review” also carries those labels into your CSV.

How a property becomes a possible opportunity

We check all relevant recorded projects before choosing a category. Repairs must have confirmed completion at least one year ago. A permit application, issue date, closure or expiry alone does not establish completion.

Older completed replacements can also qualify for review. The waiting periods are 10 years for an identified air conditioner or heat pump, 15 years for other or unspecified HVAC, and 20 years for roofing. A newer repair does not override a replacement still within its waiting period.

These are screening rules, not equipment life estimates. Roof materials and HVAC components have different lives. We do not assume that an entire system was replaced, that the recorded equipment is still installed, or that it needs replacing now.

The HVAC windows are informed by ENERGY STAR’s guidance on when to consider an evaluation. The roofing window is a conservative product rule, not a material-specific lifetime claim.

Open jobs, unclear completion, ambiguous work descriptions and new construction stay in “Needs review.” Cancelled jobs do not establish equipment age. Missing records never count as evidence that equipment is old.

What the review order means

Possible opportunities are ordered by the latest recorded completion date, oldest first, across all selected cities. Property IDs give a stable order when dates match. There is no 0–100 replacement score or estimated chance of winning a job.

The former San Diego permit-activity model is not used to qualify or order these address lists. It predicted another recorded permit, which is different from identifying work an owner needs. No prospective accuracy or conversion rate has been established for these screening rules.

Descriptions are interpreted automatically and can be wrong. Check the original records and the property’s current condition before recommending work.

Where we have records

San Diego property search covers 32 ZIP codes. Public property inventories and permit records also cover Los Angeles, San Francisco and Corona. The permit search also includes an older San Diego County archive and annual California housing reports covering all 58 counties.

We do not have every repair permit or every property in California. Cities and counties keep separate records, and one project may appear more than once. Annual housing reports and the separate San Diego County archive do not qualify addresses as possible opportunities.

Los Angeles uses the county’s residential parcel inventory within the city’s tax jurisdiction. San Francisco uses the latest residential assessment roll matched to official address and ZIP records. Corona uses residential address points marked within city limits. We also include residential properties observed in other permit types. Properties without usable addresses or unambiguous ZIPs are omitted. One representative address per property ID is shown; apartment units and shared systems are not independently verified.

Los Angeles combines building permits dating back to 1988 with standalone HVAC permits dating back to 1996. Each family has separate feeds for before 2010, 2010–2019 and 2020 onward. Earlier versions used only building permits from 2020 onward, missing most standalone HVAC jobs. Historical gaps, unmatched parcels and work performed without a permit still affect the results. A small opportunity count does not mean a small local market.

LA building permit feeds: before 2010, 2010–2019, 2020 onward. LA HVAC permit feeds: before 2010, 2010–2019, 2020 onward.

Public property sources: Los Angeles parcels, San Francisco assessment rolls, San Francisco addresses, and Corona address points.

Original permit records: City of San Diego, Los Angeles, San Francisco, Corona, San Diego County, and California housing reports.

Building details help you prepare

Both plans include available assessor facts with source links and dates. Construction year is the building’s recorded age, not the age of its roof or heating system. LA area and unit totals add the populated structure fields in the assessor record; they may cover several structures and do not verify system capacity or ownership. Blank fields mean unknown, not zero.

Job Insights shows the recorded repairs and replacements separately, including partial or unclear work. For properties with multiple units or addresses, confirm which system the permit covers and whether the homeowner, landlord, HOA or manager approves the work. New building details alone never turn an address into a possible opportunity.

Using the map and permit totals

The map shows locations supplied in public records for the current results page. Missing locations are not guessed. Moving the map does not change your search filters, and you can use the list if the map will not load.

Recent activity compares permit totals for the last 90 days with the 90 days before that. These totals cover a permit office's whole area, not just your filtered list. They count permits, not owners looking for a contractor.

Save properties and follow up

Save properties, add notes for your team and track quotes or jobs won. Add homeowner contact details your team has permission to use, and record how you got them.

The business contact list provides public company details. We have not confirmed which listed properties those companies own. Check ownership before linking a company to a property.

Review an email draft and open it in your email app when you are ready. Parcelwise does not send or track that email. If someone asks you to stop contacting them, mark them as opted out so your team sees that restriction.

Updates, subscriptions and corrections

Permit sources are checked daily and inventories weekly. Possible opportunities move to “Needs review” when a source check is over seven days old, an inventory check is over fourteen days old, or recent permit coverage is missing. Failed updates retain the previous complete records and their dates. Permit offices may publish changes late.

You see the monthly price and download allowance before subscribing. Paid access starts after payment is confirmed. Open “Billing & plan” to manage your subscription or cancel renewal. Lists are not exclusive to your business, and no jobs are guaranteed.

Use property removal to request a correction or removal. An approved removal stays in place when new records are imported. Preview forms tell you if a request has not been sent.
