Who pays for the sewer lateral in San Rafael, CA

Who is responsible for which part

Two sanitary districts serve San Rafael, and both say the sewer lateral is privately owned and the property owner's to maintain. San Rafael Sanitation District adds that this runs the entire length "including the portion that runs under the street". Which district you are in matters for other things - most of all for what happens when you sell.

The property owner

All of it, on both districts' own statements. San Rafael Sanitation District states that "a sewer lateral is the privately owned pipe that connects your home or building to the public sewer main in the street" and that "as the property owner, you're responsible for maintaining and repairing this section of pipe"; asked how far that reaches, it answers that "property owners are responsible for maintaining the entire length of the sewer lateral, including the portion that runs under the street". Las Gallinas Valley Sanitary District describes a lateral as "the segment of the sewer pipeline linking your residence to the public sewer main" and states that "the respective property owners are accountable for addressing any issues with their laterals". Its sewer system management plan goes further still: "lateral connections to the District's mains, including both the upper lateral, lower lateral, and the main connection fitting are owned by the property owner, who has responsibility for their operation and maintenance", and "maintenance of both the upper and lower laterals is the responsibility of the property owner".

What decides which applies

Which district serves your address decides more than one thing, and the districts ask you to check rather than assume: San Rafael Sanitation District advises that "there are two sanitation districts in the City of San Rafael and it's important that you confirm which district your property is located", pointing to its Service Area Map. The two agree that the lateral is the owner's. They do not agree about a sale - Las Gallinas Valley requires an inspection before close of escrow and San Rafael Sanitation does not - and Las Gallinas Valley runs a repair loan that San Rafael Sanitation does not offer. They also differ about the fitting where your pipe meets the main, and only one of them has written it down. Las Gallinas Valley's ordinance does: its section 601 provides that "sewer laterals shall be owned, maintained and repaired by the Owner of the property, which the Lateral serves", and that the whole run from the building connection to and including the wye connection or other tie-in at the sewer main "shall fall within the Owner's responsibility for installation, maintenance and repair". San Rafael Sanitation says the lateral runs the entire length under the street and stops there, without reaching the fitting either way - so in that half of the city the most expensive item on the pipe is simply not addressed, and the District is the place to settle it. One more thing if Las Gallinas Valley is your district. When it replaces its own main it will do some of your work at the same time: it "will replace the lateral-to-main connection fitting and will replace the lower lateral (up to the clean-out) if an agreement with the property owner has been reached". Ask about that before paying for the same work privately.

What is required

• When you sellInspection

  Whether a sewer lateral inspection is required when a San Rafael property is sold depends on which of the city's two sanitary districts serves it. Las Gallinas Valley Sanitary District requires one, in its ordinance's words: "upon proposed sale or transfer of property, the seller shall obtain and submit a lateral inspection report to the District prior to the close of escrow". There is no price threshold on that - the $30,000 figure the District's web page attaches to a sale belongs, in the ordinance, to building work: an inspection is required before the final inspection of permitted work "for a remodel where said remodel has a value of $30,000 or greater". The District's review costs $250 over ten business days, or $500 expedited over five, and inspection is by a licensed plumber or a Pipe Assessment Certification Program certified inspector. San Rafael Sanitation District states that it "does not require that a sewer lateral inspection be conducted prior to the sale of the property".

  What to do: Settle which district serves the address before anything else, using San Rafael Sanitation District's Service Area Map or by ringing either district. If it is Las Gallinas Valley, check next whether you are exempt before booking anybody: the ordinance excuses an owner whose predecessor "has originally installed the sewer lateral, or replaced in full the pre-existing sewer" lateral to District standards under a District permit "within twenty (20) years prior to the date of the application for a current building permit, or of listing the property for sale", and equally an owner holding a District Certification of Compliance or a clean Report of Findings from the same twenty years, or whose lateral was replaced in a District project. Proof is needed - a certificate, a paid bill or similar - and the District judges whether it suffices. Several kinds of transfer are not sales for this purpose either, among them a transfer to an heir, between co-owners, into a revocable trust, to a spouse or registered domestic partner, one resulting from a dissolution, and "a transfer from a Property Owner to a financial institution as a result of a" foreclosure. If none of that applies, start early enough for the ten-business-day standard review rather than paying for the expedited one - and ask about the District's lateral assistance loan, which can fund a repair the inspection turns up.

  Why this matters▸▾

  A sale inspection here cannot cost you a new lateral, and that is the opposite of what most sellers fear. Where the inspection is triggered by a sale, the ordinance limits what the District can require to "elimination of illegal connections" - the roof drains and yard drains feeding the sewer - and says in terms that "repair or replacement of the lateral will not be required as a result of inspections performed pursuant to this section". A bad report may still be something a buyer negotiates over, but it is not a District order to dig. No other city covered here answers the underlying question two ways: a seller on one side of a district boundary must produce an inspection before escrow can close and a seller on the other side need do nothing, and the boundary is not a thing most people know runs through their city. San Rafael Sanitation District - the district that does NOT require it - is the one that warns about this, advising that "there are two sanitation districts in the City of San Rafael and it's important that you confirm which district your property is located". The timing is where it bites: ten business days for a standard review, or $500 to have it done in five.

Assistance programmes

• Las Gallinas Valley Sanitary District sewer lateral assistance loan

  A loan rather than a grant: "customers within the District can apply for a loan of up to $15,000 from the program, allowing them a 10-year period to repay the borrowed amount at a 2-percent interest rate". Those figures are the code's as well - a maximum principal of $15,000, a ten-year term, and interest at "two percent (2%) per annum". What the page does not say is how you repay it. The amount becomes a lien on the property, collected in semi-annual instalments added to the Marin County tax roll "at the same time and in the same manner as county taxes are collected", with the agreement recorded at the County Recorder's office; the code states the lien is "of the same force and effect as other liens for taxes". Two terms in your favour sit alongside that: there is "no prepayment penalty", and the schedule is not accelerated "upon the sale or transfer of the property", so an outstanding balance need not be cleared to sell. Title search and recording fees are yours and the District may add them to the principal. The permit and the final inspection the work needs are free.

  Open to customers of Las Gallinas Valley Sanitary District, which serves part of San Rafael and the unincorporated area north of it - not to the rest of the city, which is served by San Rafael Sanitation District and has no equivalent programme. The District states that "customers within the District can apply", and describes the programme as aimed at the many homes in its area over fifty years old whose laterals have never been repaired or replaced. Confirm which district serves the address first. The District's code adds conditions its web page does not. Your lateral has to have been surveyed on video and rated under the Pipeline Assessment Certification Program, and that survey has to find at least one defect rated under it - a lateral you simply want replaced before it fails will not qualify. The property must be clear of delinquent taxes, special assessments and assessment loans, or you must show an arrangement to clear them, and the owner must be "in good standing with no claims, no active lawsuit and/or no funds outstanding due to District". Money is limited and spoken for in order: it goes first to properties caught by that year's Sewer Improvement Project, and then, if any is left, to other repairs, with "sewer laterals in the worst condition" given priority. If your property is not part of the current year's project you will also need three quotes from a licensed contractor, and the District pays the contractor directly rather than paying you.
