El arrendatario constató el estado del rodapié y la lechada.

Arrendatario means tenant or lessee. It is a correct and common word, but it sounds more formal, legal, or administrative than inquilino.

A useful contrast is:

• arrendatario = tenant
• arrendador = landlord / lessor

So this sentence sounds a bit like something from a report, inspection, or legal document rather than casual conversation.

Constató is the 3rd person singular preterite of constatar.

That tells you:

• who did the action: el arrendatario = he / she / the tenant
• when/aspect: it was a completed action in the past

So the sentence presents the inspection/check as a finished event.

Compare:

• constata = he/she confirms, notes
• constataba = he/she was confirming / used to confirm
• constató = he/she confirmed / noted

In this sentence, constató fits because the tenant checked or verified something at a specific moment.

The accent marks show where the stress goes.

• constató is stressed on the last syllable: con-sta-TÓ
• rodapié is stressed on the last syllable: ro-da-PIÉ

In constató, the accent is especially important because it also distinguishes it from constato, which means I confirm / I note in the present tense.

So:

• constato = I confirm
• constató = he/she confirmed

Del is the contraction of de + el.

So:

• del rodapié = de el rodapié = of the baseboard / skirting board

In standard Spanish, this contraction is normally obligatory.

So you say:

• el estado del rodapié

not:

• el estado de el rodapié

This is because Spanish can omit a repeated preposition in coordinated phrases.

So del rodapié y la lechada is understood as:

• del rodapié y de la lechada

In other words, el estado applies to both nouns.

That said, many learners find the fully repeated version clearer:

• El arrendatario constató el estado del rodapié y de la lechada.

That version is a bit more explicit and may feel easier to parse.

It is normal and correct, but it sounds fairly formal. It is common in:

• reports
• inspections
• legal or technical writing
• official statements

In more everyday Spanish, you might hear:

• comprobó = checked / verified
• revisó = inspected / checked
• vio = saw / noticed
• observó = observed / noticed

So constató gives the sentence a more formal, report-like tone.

In Spain:

• rodapié = the skirting board / baseboard along the bottom of a wall
• lechada = grout, especially the material used in tile joints

A couple of useful notes:

• rodapié is masculine: el rodapié
• lechada is feminine: la lechada

Also, lechada can have other meanings in other contexts, such as a slurry or milky mixture, but in a home-repair or property-inspection sentence, grout is the natural meaning.

Spanish uses definite articles more often than English does.

Here, the nouns are treated as specific or contextually known:

• el arrendatario = the tenant being discussed
• el estado = the condition/status being evaluated
• la lechada = the grout in that property or area

In English, you might sometimes reduce or restructure this, but in Spanish the articles sound completely natural.

Because el estado can refer to the overall condition being checked.

The sentence is basically treating the baseboard and the grout as items whose condition was assessed together.

So singular estado is natural here. It works like:

• the condition of the baseboard and the grout

If you wanted to make the link to both items more explicit, you could say:

• el estado del rodapié y de la lechada

But estado still stays singular because it refers to one general idea: condition.
