What should you check before buying land in Temecula?

Before buying land advertised as Temecula, ask for the records that establish its jurisdiction and legal lot status. Use those records to identify the agencies that can answer questions about your proposed building, water, septic, hazards, and taxes.

This is general information and not legal advice.

Is the lot actually inside Temecula?

Confirm whether the parcel is inside the City of Temecula or in unincorporated Riverside County. Inside city limits, the city’s planning and building rules apply. Outside, Riverside County’s rules apply.

Land advertised as “Temecula” may be outside city limits. Using Census 2020 boundaries, Insider’s approximate measurement by land area puts only about one fifth of the 92590 ZIP Code area and about one eighth of the 92592 ZIP Code area inside the city. Most of the remaining land is in unincorporated Riverside County.

Those measurements use Census Bureau ZIP Code Tabulation Areas, which approximate ZIP Code areas. They describe the broader geography; ask the city or county to confirm jurisdiction for the lot before relying on planning or building guidance.

Was the lot legally created?

Ask the city or county for a compliance determination under the Subdivision Map Act. Government Code 66499.35(a) allows an owner or a buyer under a contract of sale to request a determination of whether the property complies with the act and local ordinances enacted under it.

The local agency must make that determination. If the property complies, the city or county records a certificate of compliance. A buyer under contract can make the request directly, and the agency may impose a reasonable fee.

Ask about existing map records before requesting another document. Under section 66499.35(d), a recorded final map, parcel map, official map, or approved certificate of exception constitutes a certificate of compliance for the parcels described in it.

Have the agency identify which record covers the lot and show how the parcel is described in that record. Keep a copy for your purchase review.

What if the parcel does not comply?

If the property does not comply, Government Code 66499.35(b) requires the local agency to issue a conditional certificate of compliance. The statute requires its conditions to be met before a subsequent permit or other approval for development of the property is issued.

When a seller or document refers to a certificate, establish whether it is a certificate of compliance or a conditional certificate of compliance. Request the actual recorded document so you can read any conditions.

For a “conditional” certificate, ask the responsible agency to explain each listed condition and what satisfying it would involve for the development approval you intend to seek. Use the document’s wording in your request so the agency can address the requirement directly.

What can you build on the parcel?

Give the responsible planning department a description of your proposed use and building. Ask what can be built, which minimum lot size rules apply, and which planning documents govern the proposal. Direct these questions to city planning for land inside Temecula and Riverside County planning for land outside it.

For wine country land, Riverside County publishes a “Temecula Valley Wine Country Community Plan.” Land in the wine country area outside city limits falls under county planning. Ask the county whether that plan and any other planning documents apply to the lot.

A compliance determination addresses the parcel’s status under the Subdivision Map Act and related local ordinances. Obtain planning’s answer about the proposed development as well; the existence of a compliance record or community plan does not answer what you can build.

How should you check water and septic?

Identify the water district that serves the parcel and ask it to confirm water availability for your proposed project. Request an answer for the lot you are considering rather than relying on information about a neighboring property.

If the lot would need septic, contact the Riverside County Department of Environmental Health. It lists a “Septic Systems” program and a “Local Agency Management Program for Onsite Wastewater Treatment Systems.”

The county’s septic page requires an OWTS Construction Application for installation, repair, or modification of all septic systems within unincorporated Riverside County or its contracted cities. Ask Environmental Health which application requirements apply to your proposal.

For a new septic system, the page also requires a building permit from the local building and safety agency. Its listed supporting materials include:

• A percolation report with 3 sets of detailed plans, signed by a Professional of Record (PR) registered with the department.
• A floor plan of the structures the system will serve.
• Documentation of established water service, such as approved plans, a water bill, or other documentation.

Plan for the percolation report and confirmed water service before a septic permit. Ask Environmental Health what documentation it needs for your application; this checklist does not establish whether the parcel can receive a permit.

The page also lists separate “Temecula Wine Country Requirements.” Ask the department whether those requirements apply and obtain them for review.

Which hazard information should you review?

Check the parcel’s fire hazard zone and request its natural hazard disclosure. Review the disclosure itself rather than drawing a conclusion from a general description of Temecula or the surrounding area.

Use Insider’s guide to natural hazard disclosure reports alongside the document. If you need an explanation, identify the statement in the disclosure that prompted your question and include it in your follow-up.

What should you check about property taxes?

Account for reassessment and a supplemental property tax bill when evaluating the purchase. Under Revenue and Taxation Code 75.10, a change in ownership of land leads to a new appraisal at full cash value, which can produce a supplemental tax bill.

Read the California supplemental property tax bill guide before the transfer and note any questions about the ownership change you are considering.

Also ask whether Mello-Roos applies to the parcel. Insider’s Mello-Roos guide provides background, but its inclusion in a buyer checklist does not establish that a particular lot has it.

The short version

Before making your purchase decision, assemble the jurisdiction confirmation, applicable compliance record, planning response, water information, septic requirements if needed, hazard disclosure, and tax questions in one review file. Mark unanswered requests with the agency or district responsible for responding so you can follow up before treating the review as complete.
